Bovine,in vitro maturation,maturation time - Abstract
Primer oocytes (n=157) collected from ovaries of slaughtered cows were matured at 39°C with 95-100% humidity and under a gas mixture of 5% O 2 , 5% CO 2 and 90% N 2 for 22 (n=52), 24 (n=52) and 26 (n=53) hours. Modified Parker's Medium (MPM) supplemented with FSH and 20% ECS was used as maturation medium. At the end of these periods all oocytes were fixated in ethanol:acetic acid in the ratio of 3:1 for 24 hours and stained by %2 aceto-orcein to evaluate the maturational criteria. At the 22, 24 and 26-hours maturation groups, 23(%44.2), 27 (%51.9) and 30 (%56.6) oocytes reached the metaphase I and II stages, respectively. The difference among the groups was not important statistically (p>0.05).

Primer oocytes (n=520) collected from ovaries of slaughtered cows were divided into 3 groups, and matured at 39ºC with 95-100% humidity and under a gas mixture of 5% O 2 , 5% CO 2 and 90% N 2 for 22, 24 and 26 hours. Modified Parker's Medium (MPM) supplemented with FSH and 20% ECS was used as maturation medium. At the end of these periods, oocytes (22 h.=122, 24 h.=143 and 26 h.=255) were taken into Tyrode-lactate medium supplemented with BSA, heparin and PHE, and frozen-thawed bull semen was add after swim-up procedure (10µl@400.000 spermatozoa/30-35 oocytes). Oocytes matured in 3 groups were kept with spermatozoa for 14, 16, 18, 20, 22 and 24 hours. At the end of these time periods all oocytes were fixed, stained and examined by phase-contrast microscope. In total 42 (72.4%), 38 (69.1%) and 100 (84.7%) oocytes relating to the maturation groups, male and female pronuclei were synchronised. Difference between the 26 h. group and the other groups was highly significant (c 2 , p

Mouse,embryo,medium,BSA,protein - Abstract
Various BSA (bovine serum albumin) levels and media effects on development of 2-cell stage mouse embryos in in vitro culture were investigated in this 2 stage study. In the first stage, 1400 2-celled mouse embryos were cultured in 2 various BSA-bearing culture media for 96 h and directly observed microscopically. In the second stage, 1024 2-celled mouse embryos cultured for the same period and cell numbers (nuclei of cells) were determined by staining techniques. Embryos were cultured in both stages in M 16 and Whitten's media containing 0 (control), 0.3, 1, 3, 9, 18 and 36 mg/ml of BSA. The highest blastocyst rate was 94.57% ± 7.43, observed in 3 mg/ml BSA-containing Whitten's medium group (P < 0.05). The highest hatching + hatched blastocyst rates were obtained in the same group with 67.70% ± 25.22. The highest nucleus number in the M 16 medium was in the 1 mg/ml BSA group (95.45 ± 9.61). In the M16 medium group, the 3 mg/ml BSA group showed the highest development rate in the first stage of the study; however, the nucleus numbers in this group (81.37 ± 18.31), were significantly lower than the nucleus numbers of the 1 mg/ml BSA group (P < 0.05). It was concluded that the optimal benefit to in vitro culture of 2-cell mouse embryos could be maintained when BSA was used as a protein source at 1 mg/ml and 3 mg/ml doses, and that M16 or Whitten's media could be used successfully as a culture medium. Developmental evaluations of in vitro cultured mouse embryos could be confusing when only the native route was employed, and a staining technique could give more reliable results.

The types and rates of acrosome and other (head, mid-piece and tail) abnormal spermatozoon types were determined by the Spermac® staining technique. Semen from 5 stray tom cats under the same management conditions was used. Semen collection was performed under general anesthesia by electro-ejaculator once a week for 5 weeks. After ejaculation the semen was diluted by 100 µl of 0.9% NaCl solution and stained with Spermac® stain for morphological evaluation. The morphological criteria were acrosome, other (head, mid-piece and tail) and total morphological defect rates, and were 9.20 ± 2.55%, 9.20 ± 3.49% and 18.40 ± 4.79%, respectively. It was concluded at the end of the study that the Spermac® staining technique could provide a detailed observation of cat spermatozoa, especially the acrosomal region, and could be employed in the determination of acrosomal defects.

8.0ZET. Çalışma iki aşamada gerçekleştirildi. Birinci aşama farelerde süperovulasyon, embriyoların kazanılması ve kazanılan embriyoların değişik miktarlarda BSA içeren farklı kültür medyumlarında 96 saat süreyle kültürlerini ve bu süreç içerisinde direkt mikroskobik bakı (natif muayene) ile embriyonik gelişimsel kontrollerini kapsamaktadır. İkinci aşama ise, aynı şekilde kazanılan embriyoların yine aynı şartlar altında 96 saat süreyle kültürü ve in vitro kültürün her 24 saatinde bir olmak üzere hücre çekirdeklerinin boyanarak, embriyonik hücre sayılarının tespiti yöntemiyle embriyonik gelişim kontrollerinin yapılışını içermektedir. Çalışmanın birinci aşamasında, embriyo eldesi amacıyla 94 dişi farenin plak gösteren 72 tanesi ve bunların tohumlanması içinde 20 adet erkek fare kullanıldı. Süperovulasyon, 5 I.U PMSG enjeksiyonunu müteakip 48 saat sonra yine 5 I.U. hCG enjeksiyonu ile gerçekleştirildi. Yapılan ovidukt yıkamalarında fare başına ortalama 18.16 ± 8.65 adet iki blastomerli embriyo, 1.26 ± 0.96 adet döllenmemiş oosit ve 0.39 ± 0.70 adet dejenere embriyo düştüğü tespit edildi. Çalışmanın ikinci aşamasında ise, embriyo eldesi amacıyla 75 farenin plak gösteren 50 tanesi kullanıldı. Senkronizasyon aynı yöntemle yapılırken bu gruptaki farelerden elde edilen iki blastomerli embriyoların fare başına ortalaması, 20.20 ± 4.06, döllenmemiş oosit ortalaması 2.54 ± 1.61 ve dejenere embriyo ortalaması da 1.57 ± 1.09 olarak bulundu. Birinci aşamada elde edilen iki blastomerli embriyolar, M 16 ve Whitten's medyumlarının sırasıyla 0 (kontrol), 0.3, 1, 3 9, 18 ve 36 mg/ml BSA İçeren gruplarında ve aynı koşullar altında (% 5 C02, % 5 02, % 90 N2'li gaz ortamı ve % 100'e yakın rutubetin sağlandığı 37°C'lik inkübatör ortamı) 96 saat süreyle kültüre edildiler. Embriyoların gelişimsel kontrolleri in vitro kültür periyodunun her 24 saatinde bir kere olmak üzere natif yöntemle yapıldı. M 16 medyumunun 0 (Kontrol), 0.3, 1, 3, 9, 18 ve 36 mg/ml miktarlarında BSA içeren gruplarında kültüre edilen embriyoların gelişim oranları arasında, in vitro kültürün ilk 24 saati itibarıyla istatistiksel açıdan herhangi bir fark bulunmadı (p>0.05). Kültür periyodunun 48 saatlik döneminde ise en yüksek gelişim düzeyi % 100.00 ± 0.00 ile 3 mg/ml BSA içeren grupta meydana geldi. Bu değer ile 0.3,1 ve 9 mg/ml BSA içeren gruplardaki değerler arasında istatistiksel anlamda herhangi bir fark saptanmadı (p>0.05). Buna karşın, bu değer ile BSA' nın bulunmadığı (0 mg/ml) ve yoğun olarak bulunduğu (18 ve.36 mg/ml) gruplardaki değerler arasındaki farkların istatistiksel açıdan önem taşıdığı saptandı (p0.05), buna karşın diğer gruplarla ise arasındaki farkların önem taşıdığı saptandı (P0.05). In vitro kültürün 48 saatlik döneminde ise en yüksek gelişim oranı % 96.52 ± 6.70 ile yine 3 mg/ml BSA grubunda saptandı. Yapılan istatistiksel değerlendirmede bu değer ile 0,0.3 ve 1 mg/ml BSA gruplarında bulunan değerler arasındaki farkların önem taşımadığı gözlenirken (p>0.05), bu değer ile BSA'nın yoğunlaştığı (9, 18 ve 36 mg/ml) gruplarındaki değerler arasındaki farkların 3 mg/ml BSA grubu lehine olmak üzere önem taşıdığı saptandı (p0.05). Buna karşın bu değer ile BSA'nın bulunmadığı (0 mg/ml) ve yoğun olarak bulunduğu (9, 18 ve 36 mg/ml) gruplarda bulunan değerlerle arasındaki farkların, 3 mg/ml BSA grubu lehine olmak üzere önem taşıdığı belirlendi (p0t?6^ M4? - ve - Whrtten^ medyumlarının her ikisinde de en yüksek hatching + hatched blastosist toplam oranlarının sırasıyla % 44.34 ± 25.94 ve % 67.70 ± 25.22 ile 3 mg/ml BSA içeren gruplarında gerçekleştiği görüldü. Yapılan istatistiksel değerlendirmede bu iki değer arasında, Whitten's medyum grubu lehine bulunan 23.36'lık farkın önem taşımadığı belirlendi (p>0.05). ikinci aşamada ise; iki blastomerli fare embriyoları yine aynı medyumların aynı miktarlarda BSA içeren gruplarında 96 saat süreyle kültüre alındılar. Bu aşamada, embriyoların gelişimsel kontrollerinin daha sağlıklı bir şekilde yapılmasına yönelik olarak, in vitro kültür periyodunun her 24 saatlik döneminde bir olmak üzere (ilk 24 saat hariç) embriyolar hücre çekirdek boyası ile boyanarak embriyonik hücre sayıları tespit edildi. 74M 16 medyumunun24 ve 48 saatlik kültür periyotlarında en yüksek embriyonik hücre sayısı ortalamaları sırasıyla 9.6 ± 3.2 ve 43.65 ± 9.65 ile 1 mg/ml grubunda gözlenirken, bu değer ile diğer tüm gruplarda bulunan değerler arasında istatistiksel açıdan önemli oranlarda farklılıklar gözlendi (p0.05). Buna karşın diğer tüm BSA gruplarında saptanan ortalama değerler, 3 mg/ml BSA grubundaki bu değerlerin oldukça altında gerçekleşti (p>0.05). Gerek M16 ve gerekse Whitten's medyumlarında, BSA miktarlarının sıfıra doğru azalması ve 36 mg/ml'ye doğru artması durumlarında embriyonik hücre sayısı ortalamalarında önemli oranlarda düşüşler gözlendi. Farklı medyumların aynı miktarlarda BSA içeren gruplarının birbirleriyle yapılan karşılaştırmalarında hiçbir BSA miktarı ve hiçbir saat açısından gruplar arasında istatistiksel anlamda önemli farklara rastlanmadı (p>0.05). Sonuç olarak, iki hücreli fare embriyolarının in vitro kültüründe protein kaynağı olarak BSA'nın olumlu katkılar yapabildiği ve kültür medyumu olarak gerek M16 ve gerekse de Whitten's medyumlarının rahatlıkla kullanılabileceği görüldü. Ancak in vitro kültür periyodu sonunda optimal sonucu elde etmek için; M16 medyumu kullanılacaksa 1 75mg/ml, Whitten's medyumu kullanılacaksa 3 mg/ml BSA yoğunluklarının tercih edilmesi gerektiği ortaya çıktı. Ayrıca embriyoların in vitro kültür ortamındaki gelişimlerinin sadece natif yolla yapılmasının yanıltıcı sonuçlar verebileceği, bunun yanında araştırmada kullandığımız hücre çekirdeklerinin boyanmasına dayalı yöntemin daha sağlıklı sonuçlar verebileceği kanısına varıldı. 76 9.SUMMARY EFFECT OF VARIOUS BSA LEVELS ON DEVELOPMENT OF MOUSE EMBRYOS IN IN VITRO CULTURE The study was performed in two stages. In the first stage, mice were superovulated, embryos were recovered, cultured in different culture media containing various levels of BSA for 96 hours and the control of embryonic developments by direct microscopic observation were done. In the second stage the culture of the embryos under same conditions for 96 hours and control of embryonic development at every 24 hour during the in vitro culture period by nuclear staining were performed. Out of 94 female mice. 72 with vaginal plug and 20 male mice for matings were used. Superovulation was achieved by 5 i.u. PMSG injection and 5 i.u. hCG injection 48 hours after that. 18.16 ± 8.65 two blastomere embryos, 1.26 ± 0.96 non fertilized oocyte and 0.39 ± 0.70 degenerated embryo per female were recovered by oviduct flushings. In the second stage of the study 50 plug bearing female out of 75 were used for embryo collection. By the same superovulation method 20.20 ± 4.06 two blastomere embryos, 2.54 ± 1.61 non fertilized oocytes and 1.57 ± 1.09 degenerated embryos Per female were recovered in this group. The two blastomer embryos collected in the first group were cultured for 96 hours in M 16 and Whitten's media containing 0 (control), 0.3, 1, 3, 9, 18 and 36 mg/ml BSA respectively under same conditions (at 37 ° C incubator under air containing 5% C02, 5% 02, 90% N2 and rearly 100% humidity). Developmental stages of embryos were observed at every 24 hour during in vitro culture period by neat observation technique. No statistical differences was observed among the M 16 medium groups containing 0 (control), 0.3, 1, 3, 9, 18 and 36 mg/ml BSA at the first 24 hours (p> 0.05). Highest development (100 ± 0.00 %) was observed in 3 mg/ml BSA containing group at 48. hour. No statistical difference was observed between these results and the groups (p> 0.05). Although there were important statistical differences (p< 0.05) between these results and the results of the groups containing lowest (0 mg/ml) and highest (18 and 36 mg/ml) BSA levels. Highest development rates at 72. and 96. hours of the in vitro culture period were 88.01 ± 16.06 % and 84.74 ± 17.61 % in 3 mg/ml BSA containing group. The difference between these values and the values of 1 and 9 mg/ml BSA containing groups was insignificant (p> 0.05), and between the values of other groups was significant (p 0.05). Highest development rate at the 48 hour of in vitro culture was 96.52 ± 6.70 % in 3 mg/ml BSA group. No important statistical difference was observed between this value and the values of 0. 0.3 and 1 mg/ml BSA containing groups (p> 0.05). Whilst the difference between this value and the values of the groups containing higher levels of BSA (9, 18 and 36 mg/ml) was important (p0.05). The difference between this result and and the results of the group without BSA (0 mg/ml) arid the groups with higher BSA (9, 18 and 36 mg/ml) were statistically important in favor of 3 mg/ml BSA group (p0.05). Highest total hatching + hatched blastocyst rates in both M 16 and Whitten's media were 44.34 ± 25.94 % and 67.70 ± 25.22 % respectively in 3 mg/ml BSA containing groups. Statistical evaluations showed that 23.36 difference in favor of Whitten's medium was not significant (p>0.05). In the second stage of the study, two blastomere mouse embryos were cultured for 96 hours in groups containing same amounts of BSA.At this stage, in order to control the developments embryos were stained with nucleus stains and nuclei were counted every 24 hours during in the in vitro culture period (except the first 24 hour). The highest embryonic cell numbers of M 16 medium at 24 and 48 hours culture period were 9.6 ±3.2 and 43.65 ± 9.65 respectively in 1 mg/ml BSA containing group, and these values were superior statistically to the values of all other groups (p0.05). However mean values of all BSA groups, were lower than this value of 3 mg/ml BSA group (p>0.05). Important decreases were observed in embryonic cell counts with the decrease of BSA amount in both M 16 and Whitten's media towards 0 and also with increase to 36 mg/ml. In comparison of the different media containing similar BSA amount no important statistical difference was seen among all BSA groups and all time periods (p>0.05). In conclusion, it was observed that BSA is a good protein resource and could be added to M16 and Whitten's media in in vitro culture of two cell mouse embryos. It is suggested to add 1 mg/ml BSA to M 16 and 3 mg/ml BSA to Whitten's media in order to get optimal results from in vitro culture also the observation of developmental stages of the embryos in in vitro culture can be achieved more accurately by nuclei staining procedures instead of using neat observation method only. 79 85

64 9. ÖZET: Çalışmada canlı materyal olarak, saf ırk, damızlık, 2 yaşlı 5 adet (Alman Kurt, Buldog, Chow chow, Sibirya Husky, New Foundland) erkek köpek kullanıldı. Araştırma süresince, parmak maniplasyonları tekniği uygulanarak haftada iki kez olmak üzere toplam 50 ejakülat alındı. Hacim, motilite, yoğunluk, canlı spermatozoa, pH ve morfolojik muayenelerden oluşan spermatolojik özellikler saptandı. Alınan sperma 2 eşit hacime ayrılarak %1 glikoz, %10 yumurta sarılı yağsız sütlü sulandırıcı ve %1.78 sitrik asit, %1.25 fruktoz'lu Tris (%3.2) sulandırıcısı ile oda ısısında 1:1 oranında sulandırıldı. 2 saatte 5°C'ye soğutulan süt ve Tris sulandırıcıları ile sulandırılmış spermalar yine iki eşit hacime ayrıldılar. Finalde, Tris sulandırıcısı %4 - %7 gliserollü ve sütlü sulandırıcı %4 - %7 gliserollü olacak şekilde gliserolizasyon işlemi uygulanarak 4 grup oluşturuldu. Beş farklı ırk köpeğe ait spermaların motilite ve anormal spermatozoa oranları her aşamada değerlendirildi. Sperma oda ısısında sulandırıldıktan sonra ve 5°C'ye soğutulduktan sonra yapılan incelemelerde sulandırıcılar arasında önemli bir fark saptanmadı. Gliserolizasyon sonrası en yüksek motilite %79.80±6.14 ile %4 gliserollü Tris sulandırıcısında bulunurken, en düşük motilite %59.70±9.65 ile %7 gliserollü süt sulandırıcısında elde edildi (n=50). En yüksek akrozomal ve toplam morfolojik bozukluklar, %7 gliserollü süt ve Tris sulandırıcılarında saptandı. 2 saatlik ekilibrasyon sonrasında da belirtilen spermatolojik özellikler aynı doğrultuda elde edildi. 0.2 mi pelletlerde dondurma ve eritme sonrası ise en yüksek motilite %68.36±1 1.71 ile %4 gliserollü sütlü sulandırıcıda elde edildi (p

Sağlıklı embryoların (toplam 24 adet) gelişim devreleri ise, 3 kompakt morula, 5 blastosist, 2 geç blastosist, 14 adet expanded blastosist dağılı mındaydı.61 PMSG'nin 75, 150 ve 200 iü. dozlarında verildiği gruplarda elde edilen f ertili zasyon oranları sırasıyla %97.97, %97.06 ve %83.61 olarak saptandı. HMG'nin tek enjeksiyonla verildiği grupta f ertil izasyon oranı %91.83 iken, 3 enjeksiyonla verildiği grupta %75.00 oldu. C.C. uygulamasında ise f ertili zasyon oranları, 100 ve 150 mg. C.C. uygulamalarında sırası ile %66.67 ve %16.67 oldu. Aynı oran kontrol grubunda ise %93.94 olarak saptandı. Tavşan embryolarının expanded blastosist gelişim devresi, 96 saatlik embryoların bulunması gereken süreye denk kabul edildiği için, bu devredeki embryoların toplam sağlıklı embryolar içindeki oranı hesaplandı ve bu oran 75, 150 ve 200 iö. PMSG gruplarında sırası ile %66.93, %15.38 ve %16.67 iken, 3 enjeksiyonla HMG verilen grupta %32.43, tek enjeksiyonla HMG verilen grupta ise %69.54 olarak saptandı. Aynı gelişim devresindeki embryoların dağılım oranları 100 mg. C.C. grubunda %62.50, 150 mg. C.C. grubunda 0 ve kontrol grubunda ise %58.33 oldu. Elde edilen veriler ovaryumlardaki toplam oluşum, kazanılan sağlıklı embryo sayıları ve expanded blastosi st ler in oranı açısından incelendiğinde, uygulama grupları arasında tek enjeksiyonla 75 iü. HMG verilen grubun üstün olduğu saptandı. Üvulasyon oranı açısından ise 3 enjeksiyonla HMG verilen grubun daha üstün olduğu belirlendi. Fertil izasyon oranı yönünden sonuçlar incelendiğinde, tek enjeksiyonla HMG uygulanan grupta elde edilen verilerin, kontrol grubuna yakın olduğu, 75 ve 150 iü. PMSG verilen grupların sonuçlarından ise daha düşük olduğu görüldü. Bu verilerin ışığında HMG'nin tek enjeksiyonla uygulanan 75 iü.lik dozu, planlanan embryo transfer çalışmalarında en iyi sonuç veren süperovulatör ajan düşüncesi ile kullanıldı ve bu preparatın gebelik oranı üzerine olan etkisi araştırıldı. Bu62 maksat ile HMG uygulama grubunda 5 verici 10 alıcı, kontrol amacıyla da 5 verici 5 alıcı olmak üzere toplam 25 tavşanın embryo transfer çalışmalarında kullanılması planlandı. Uygulama grubundaki 5 verici tavşandan çiftleşmeden 96 saat sonra uygulanan uterus yıkaması ile elde edilen 65 embryonun (hayvan başına ortalama 13.0+_e403) değerlendirilmesi sonucu, 1 tanesinin dejenere olduğuna karar verildi. Toplam 64 sağlıklı embryonun ? alıcı tavşana transferinden hiçbir gebelik elde edilemedi. Kontrol grubunda ise 5 verici tavşandan kazanılan 27 adet embryonun (hayvan başına ortalama 5.4_+2.29) incelenmesi ile 1 tanesinin dejenere olduğu görüldü. Sağlıklı olan toplam 26 embryonun 3 alıcı tavşana transferinden bir gebelik elde edildi. 63 7. SUMMARY In order- to select the most suitable superovulator agent in rabbits, different doses of PMSG, HMG and C.C. were investigated on seven treatment groups, and a control group. Each of every 8 ovulation groups contained ten female rabbits and 8 male rabbits were used for matings. Choosing the most effective superovulator agent, 25 female rabbits were kept to evaluate the effect of this agent on pregnancy rates. 75, 150 and 200 iü. doses of PMSG were treated combined with HCG by single enjection, and 96 hours apart, ovarial findings were observed by laparatomy and all uteri were flushed. In the 75 iü. PMSG treatment group, total ovarial findings (follicle + corpus luteum) were 36.6+7,99, Out of these, 7.4+2.28 were unovulated follicles, 29.2+5,71 were corpora lutaa. The ovulation rate for this group was 79.78%. These values for the 150 iü. PMSG group were 41.1+J.Q.39 total findings, 13.5+_3.4g follicles, 27.0 + 5.90 corpora lutea, and the rate of ovulation was 66.67%. The values of the 200 iü. PMSG group were 32.4+_9,4i total findings, 9.2+_2.51 follicles and 23.2+5.80 corpora lutaa, and the rate of ovulation was 71.60%. In the group at which 75 iü. HMG was used by single injection, the mean values were ati follows, 51.3+_g.95 total findings, 8.5+_3,65 unovulated follicles, 42.8 + 6.30 corpora lutea and the rate of ovulation was 83.43%. In the group at which HMG was treated by 3 injections there were 51.1+_n,85 total findings, 4.4+_i,6i follicles, 4S.7+J.0.24 corpora lutea and the rate of ovulation was 91.39%. In the group at which 100 mg. C.C. was used by oral route, there were 11.6+_2,51 total findings, out of these 6.0+.1.15 were64 follicles, 5.6+^,45 wsr9 corpora lutea and the ovulation rata was 48.28%. At 150 mg. C.C. treated group, these values were 12.6+^.43 total findings, 7.7+.1.54 unovulated follicles, 4.9+0.89 corpora lutea, and the ovulation rate was 38.89%. In the control group which was treated only by 100 iü. HCG to stimulate ovulation, there were lU.bu.54 total findings. Out of these 3. 1+^.78 were unovulated follicles. 7.4+.0.76 were corpora lutea and ovulation rate was 70.48%. At the 75 iü. PMSG group, avarage 19.7+_s,07 cell3 were recovered per animal by uterus flushings. Out of those cells 7.77+_4,35 were ova and degenerated embryos. The total number of healthy embryos was 127. Out of those embryos 1 was compact morula, 17 blastocysts, 24 late blastocysts and 85 were expanded blastocysts. In the 150 iü. PMSG treated group, avarage 3.4+_j,,75 total findings were noted per animal. Out of those findings 2.1+_i,62 were ova and dejenerated embryos and 1.3+_o.73 were healthy embryos. Number of healthy embryos was 13, and 2 were compact morula, 7 were blastocysts, 2 late blastocysts and 2 were expanded blastocysts. In the 200 iü. PMSG treated group, avarage 6.1+^.17 cells were recovered per animal. Out of those findings 5.5+_i,75 were ova and dejenerated embryos and Û.S-M3.42 were healthy embryos. Out of the total 6 healthy embryos, 1 was compact morula, 1 was blastocyst, 3 were late blastocysts and 1 was expanded blastocyst. In the HMG single injection group, avarage 2Û.8+_5,63 cells were recovered. Out of these cells 5.7+_i,73 were ova and dejenerated embryos, and 15.1+_6.24 were healthy embryos. Total number of the healthy embryos was 151 and their developmental stages were as follows, 6 were compact morula, 18 were blastocysts, 22 were late blastocysts and 105 were expanded65 blastocysts. In the group which is treated by 3 injections of HMG, avarage 22.8+^.go cells were recovered* Out of these cells 11.7+^2*63 were ova and dejenerated embryos, and 11.1+.6.23 were healthy embryos. Total number of healthy embryos was 111 and their developmental stages were as follows, 1 compact morula, 57 blastocysts, 17 late blastocysts and 36 expanded blastocysts. In the least cell recovered C.C. group, from the 100 mg. C.C. treated does avarage 1.2+_o«55 cells were recovered. Out of those cells 0.4+_o*04 were ova, 0*8 + 0. 51 were healthy embryos. Total number of healthy embryos were 8 and their developmental stages were as follows, 2 blastocysts, 1 late blastocyst and 5 were expanded blastocysts. In the 150 mg. C.C. group avarage 0.6+_o*25 celİ3 recovered and all of those cells were ova and dejenerated embryos. In the control group avarage 3.3+_i,05 cells were recovered. 0.9+_o.54 of those cells were ova and dejenerated embryos and 2.4+_i,08 were healthy embryos* Total number of healthy embryos was 24. Developmental stages of those embryos were 3 compact morula, 5 blastocysts, 2 late blastocysts and 14 expanded blastocysts. In the groups treated with 75, 150 and 200 iü. doses of PMSG, rates of fertilization were 97.97%, 97.06% and 83.61% respectively. In the HMG single injection group, rate of fertilization was 9î.83% and in HMG 3 injections group it was 75.00%. In C.C. treated groups, rates of fertilization were as follows. In 100 mg. C.C. group 66.67% and in 150 mg. C.C. group 16.67%. In the control group, rate of fertilization was 93.94%. Since expanded blastocyst stage of rabbit embryos is considered equal to the developmental stages of 96 hours embryos, the rate of this stage embryos were calculated over the total66 healthy embryos and these rates for 75, 150 and 200 iti. PMSG groups were 66.93%, 15.38% and 16.67% respectively. This rate «as 32.43% for 3 injections HMG group and 69.54% for single injection HMG group. Rates of the embryos at same developmental stages were 62.50% for 100 mg. C.C. group, 0% for 150 mg. C.C. group and 58.33% for control group. Among the results of experiments, when total findings, recovered healthy embryos and rate of expanded blastocysts were considered 75 iü. HMG single injection group found supperior to others. When fertilization rates were compared HMG single injection groups results found to be close to the results of the control group and lower than the results of 75 and 150 iü. PMSG groups. Considering these results, single injection of 75 iü. HMG was used for superovulation in the embryo transfer investigations and its effect on pregnancy rates was examined. For this purpose, for HMG treatment 5 donor and 10 recipient rabbits and for control group 5 donor and 5 recipient rabbits were used. In the treatment group, 96 hours after mating, 65 embryos recovered by uterus flushings of 5 donor rabbits( avarage 13.0+_5,Q3 per animal). 1 embryo was dejenerated and other 64 embryos were transferred to 7 recipients. No pregnancy was obtained. In the control group, total 27 embryos recovered from 5 donor rabbits (avarage 5. 4+3*29 per animal), 1 of the embryos was dejenerated. Other 26 healthy embryos were transferred to 3 recipient rabbits and one pregnancy obtained. 82

SUMMARY The effects of low post- thaw temperatures on bull semen frozen in.25 ml. French straws were studied in the paper. Each ejaculates from five bulls regularly used twice a week for collection were diluted with Laciphos 478 extender and frozen in the straws. The study in which various thawing temperatures and times selected was carried out in three steps and used 450 straws from five bulls. In the first step, in order to arrange the optimum thawing procedure frozen straws were thawed in four different groups selected as 37°C/30 seconds, 20°C/45 seconds, 15 C/60 seconds and 5 C/90 seconds. In each thawing group, 200 straws from 40 for each bull were used. The motility values were found as 57. IX, 42.3%, 36.8% and 29.2%, the rate of abnormal acrosome were 3.2%, 11.0%, 17.7* and 31.4%, and total spermatozoa damaged morphologically are 6.9%, 18.0%, 26.6% and 40.6% respectively. The best thawing procedure for frozen bull semen packaged in.25 straws was found at 37 C/30 seconds thaw. In second step, low post- thaw temperatures in 4 different categories as 25°C, 15°C, 10°C and 5°C for 5 minutes were applied the straws thawed at 37°C/30 seconds. 200 straws from 40 for each bull were used. Percentage motilities were %38.6, %34.8, %28.9 and %26.7, the rate of abnormal acrosome were 9.7%, 13.8%, 16.8% and 21.2% and rate of total damaged spermatozoa were %17.3, %21.6, %25.2 and %30.5-95- respectively. In according to decrease in motility and increase in number of spermatozoa damaged morphogically semen values were the worst at the group for 5 C/5' post-thaw. In the last step, the post- thaw temperature for straws thawed optimally (at 37 C for 30 seconds) and applied low post- thaw temperature group at 5 C for 5 minutes in which is most effected negatively was increased to 37 C for 30 seconds as last temperature applications. 50 straws from each bull were used. In this step, While the percentage motility in 37 C/30` thaw were «57.1 the value were decreased to %26.7 by thawing at 5 C/5' and as the temperature were risen to 37 C for 30`, motility was increased by X40.3.

- Abstract
Background: Oxidative stress results from an imbalance between the induction of reactive oxygen species and the ability of cells to metabolize them. Numerous markers can be used to assess the level of oxidative stress. Thiol-disulfide homeostasis (TDH) and ischemia-modified albumin (IMA) are some of them. The aim of this study is to investigate the role of TDH and IMA, which are indicators of oxidative stress, in older patients with osteosarcopenia (OS)., Methods: The study was conducted cross-sectionally in a geriatrics outpatient clinic. Patients who applied to the outpatient clinic for three months were included in the study. Patients with acute infection, delirium, malignancy, severe liver, heart or kidney dysfunction and who did not give their consent for the study were excluded from the study. The study was conducted with 136 patients. Sarcopenia was diagnosed according to muscle ultrasonography (USG) and handgrip strength (HGS) results. Osteopenia/osteoporosis was diagnosed according to bone mineral densitometry (BMD) results. The combination of osteopenia/osteoporosis and sarcopenia was accepted as OS., Results: Native thiol, total thiol value and nativethiol /totalthiol*100 values were significantly lower in the group with OS (respectively; value = 265 ± 53.8 standard deviation (SD) μmol/L, p = ≤ 0.001; value = 295.33 ± 55.77 SD μmol/L, p = 0.001; value = 90.06 (2.8) interquartile ranges (IQR), p = 0.033). Disulfide/native thiol*100 and disulfide/total thiol*100 values were significantly higher in the group with OS (respectively; value = 5.5 (1.7) IQR, p = 0.033; value = 4.97 (1.4) IQR, p = 0.034)., Conclusion: In our study, the role of oxidative stress in OS was demonstrated by using TDH as an oxidative stress parameter., (© 2024.

- Abstract
Aim: To evaluate relationship between frailty and oxidative stress through thiol/disulfide homeostasis parameters [Native thiol (NT), total thiol (TT), and disulfide levels (D), disulfide-native thiol (D/NT), disulfide-total thiol (D/TT), native thiol-total thiol (NT/TT) ratios, and ischemia-modified albumin levels (IMA)]., Materials and Methods: In total, 139 community-dwelling older adults were included. The frailty status, defined by the FRIED frailty index (FFI) and Clinical Frailty Scale (CFS), and comprehensive geriatric assessment results compared with thiol/disulfide homeostasis parameters and ischemia-modified albumin levels., Results: NT and TT levels were significantly lower in the frail group (respectively; p = 0.014, p = 0.020). The FFI scores were correlated with the levels of NT, TT, D/NT, D/TT, and NT/TT (respectively; r = - 0.25, r = - 0.24, r = 0.17, r = 0.17, r = - 0.17). The significant correlation could not be retained with the CFS scores. In ROC analysis, the AUC for NT was calculated as 0.639 in diagnosing frailty according to the FFI (95% CI 0.542-0.737), AUC was 0.638 for TT (95% CI 0.540-0.735), and AUC was 0.610 for NT/TT (95% CI 0.511-0.780). The AUC was calculated as 0.610 for both D/NT and D/TT in diagnosing physical frailty (95% CI 0.511-0.708)., Conclusion: Thiol/disulfide homeostasis parameters can be a potential biomarker in diagnosing physical frailty. However, further studies are needed for diagnosing frailty defined with cumulative deficit models., (© 2024. The Author(s), under exclusive licence to European Geriatric Medicine Society.)

Background: The aim of this study is to validate the Turkish version of the 5-minute cognitive test (FCT) in a geriatric population., Materials and Method: In total, 61 participants aged ≥65 years with normal cognitive functions, mild cognitive impairment (MCI), and early stage dementia were included. The FCT was compared to the standardised Mini Mental State Examination (MMSE) and the Qmci-TR (quick mild cognitive impairment) test., Results: Test reliability for the FCT was strong (Cronbach's α = 0.747). We demonstrated a strong correlation of FCT scores with MMSE and Qmci-TR scores (respectively, r = 0.730, P < 0.001, r = 0.723, P < 0.001). The fact that the scores obtained in the dementia group were significantly lower also showed that the test can be used reliably in the differentiation of MCI and early dementia (P < 0.001)., Conclusions: The FCT is a brief, reliable, and valid cognitive screening test for screening dementia at early stages in a Turkish geriatric population., (© 2023 Japanese Psychogeriatric Society.)

- Abstract
Background and Purpose:
Atrial fibrillation diagnosed after stroke (AFDAS) is a new term used for AF resulting from autonomic dysregulation. It is associated with a lower stroke recurrence compared to patients with known AF before a stroke (KAF). The aim of the study was to explore the characteristics and mortality rates in AFDAS patients.
., Methods:134 ischemic stroke patients (66.1±14.2 years old, n=73 male) were consecutively included in the study. While patients who had known AF with anticoagulant therapy were grouped as KAF, patients with newly documented AF rhythm (either by daily ECG or ambulatory ECG monitoring) were classified as AFDAS. All patients were followed for 1 year to obtain all-cause mortality, cardiac mortality, and neurogenic mortality.
., Results:Of the 134 stroke patients, AF was detected newly in 38 patients and grouped as AFDAS. KAF patients had higher CHA2DS2VASc scores, hs-CRP and NT-proBNP levels, and more insular cortex involvement than the SR group. During the one-year follow-up, 35 stroke patients died. The mortality rate was significantly higher in patients with KAF (12/22; 54.5%) while the mortality rates were similar between AFDAS patients (11/38; 28.9%) and patients with sinus rhythm (SR) (12/74; 16.2%). KAF was an independent predictor when adjusted by age, sex, CHA2DS2VASc and NIHSS scores, and insular cortex involvement. While AFDAS had increased the mortality risk compared to SR, the difference was not significant in univariable and multivariable models.
., Conclusion:AFDAS patients have similar CHA2DS2VASc scores and mortality rates to patients with SR, which implies that AFDAS might be a relatively benign form of AF.

- Abstract
Background: Frailty, is a geriatric syndrome that reduces the resistance to stress situations caused by activities of daily living and increases morbidity and mortality. We hypothesized that a decrease in orexigenic peptides or an increase in anorexigenic peptides might be associated with frailty. We aimed to investigate the relationship between frailty and six appetite-related peptides: ghrelin, neuropeptide Y (NPY), agouti-related peptide (AgRP), cocaine-amphetamine-associated peptide (CART), peptide YY, and alpha MSH (α-MSH)., Methods: This cross-sectional study was conducted on 85 older adults who visited the outpatient clinic. All patients underwent comprehensive geriatric assessment. Frailty status was assessed using the Fried frailty index. Plasma levels of six appetite-related peptides were studied., Results: The mean age was 73.7 ± 5.4 years, 27 (31.8%) of the patients were male, and 32 of the patients (37.6%) were frail. While plasma levels of ghrelin, NPY and AgRP were significantly lower in frail patients, CART and α-MSH levels were higher compared to non-frail patients (p < .05 for all). Peptide YY was found to be higher in the frail group, however, the difference did not reach statistical significance (p = .052). In multivariate logistic regression analysis, the ghrelin, AgRP, CART, and α-MSH levels were independent predictors of frailty. Moreover, a weak correlation was found between all peptides(except NPY) and handgrip strength and Lawton-Brody score., Conclusion: Ghrelin, AgRP, CART, and α-MSH levels were found to be independent predictors of frailty. Our results suggest that appetite-related peptides might be playing roles in the pathogenesis of frailty. Further larger prospective studies are needed to test this hypothesis.

- Abstract
Purpose: Aging impacts muscle strength and elasticity, which in turn influence dynamic balance, walking speed, and physical performance. We aimed to evaluate the relationship between the elasticity of leg muscles and incidence of falls in older adults., Methods: We conducted a prospective cohort analysis with outpatients from a geriatric clinic. Any history of falls in the past year was recorded. Timed up and go test, muscle thickness, and handgrip strength tests were performed. Elasticities of the gastrocnemius medialis (GM) and rectus femoris (RF) muscles were evaluated using shear wave elastography. Patients self-recorded their falls, and additional phone calls were made to them each month for 6 months., Results: The median age of the patients (n = 55) was 72 years (66-86); and 72% were women. The GM showed significantly lower elasticity in patients with history of falls in the past year than in those without it (8.08 kPa [3.90-16.17] vs. 9.70 kPa [4.99-20.95]; p = 0.028). A similar negative correlation between GM and fall incidence was noted among those with additional falls during the follow-up period (6.96 kPa [3.90-12.41] vs. 9.13 kPa [4.99-20.95]; p = 0.019). GM elasticity was significantly correlated with the timed up and go test score (r = - 0.612, p < 0.001), handgrip strength (r = 0.384, p = 0.015), and muscle thickness (r = 0.232, p = 0.049). No such associations were observed for the RF muscles., Conclusion: GM muscle elasticity is associated with alterations in muscle structure that may lead to falls in older adults. Therefore, muscle elasticity may be a fall predictor in older adults., (© 2023. The Author(s), under exclusive licence to European Geriatric Medicine Society.)

- Abstract
Objectives: Osteosarcopenic obesity (OSO; also known as adiposity) is the combination of three critical conditions. This study aimed to define OSO using muscle ultrasonography (US), and examine the relationship between OSO and frailty compared with its constituent components., Methods: A total of160 geriatric patients with a body mass index of ≥30 were enrolled in the study. We obtained US measurements of the rectus femoris thickness and cross-sectional area (RFCSA). OSO was defined as the combination of low muscle function (defined by handgrip strength <27 kg in men and <16 kg in women), low muscle mass (RFCSA ≤5.22 cm
2 ), and the clinical diagnosis of osteoporosis. The modified Fried Frailty Index and Clinical Frailty Scale were used to identify frailty., Results: The median age of participants was 72 y, and 83% (n = 137) were female. Patients were divided into four categories: Obese (n = 72; 43.6%), osteoporotic obese (n = 44; 26.7%), sarcopenic obese (n = 19; 11.5%), and osteosarcopenic obese (n = 25; 15.2%). In the subgroup analysis, the prevalence of frailty was significantly higher in the OSO group than in the other groups on both frailty scales (P < 0.05). The regression analysis showed that OSO significantly increased frailty status when adjusted for confounders detailed in Table 1 (Fried Frailty Index: odds ratio: 5.10; 95% confidence interval, 1.669-15.132; P = 0.004; Clinical Frailty Scale: odds ratio: 3.765; 95% confidence interval, 1.236-11.465; P = 0.020)., Conclusions: US-defined OSO is strongly associated with frailty in older adults according to the first study to define OSO using RFCSA measures., (Copyright © 2022 Elsevier Inc.

- Abstract
Background: Malnutrition is a problem that greatly affects patients with hematological malignancy (HM) throughout the course of illness. Intensity of the malignancy treatment, inadequate energy intake, complex procedures such as hematopoietic stem cell transplantation, and treatment side effects are contributing factors for malnutrition in HM patients. The aim of this study was to compare the accuracy of the modified Nutrition Risk in Critically Ill (mNUTRIC) score and Nutrition Risk Screening 2002 (NRS-2002) in predicting hospital and long-term mortality of HM patients in the intensive care unit (ICU) and to identify effects of malnutrition on ICU mortality., Methods: This prospective observational cohort study was conducted in a university teaching hospital tertiary ICU service. During the study period, 112 HM patients who were >18 years old were admitted to the ICU. We excluded the patients who were discharged or died within 24 h from the statistical analysis. The patients were followed for 3 years after discharge for long-term mortality., Results: Twenty-nine patients died within 24 h of admission and were excluded from the study; therefore, statistical analysis was done for 81 patients. Logistic regression analysis demonstrated that high malnutrition risk, according to the NRS-2002 score, was associated with greater odds of ICU mortality (P = 0.002, odds ratio = 19.16)., Conclusion: In this study, we showed that NRS-2002 is superior to mNUTRIC score in predicting ICU mortality in patients with HMs. mNUTRIC score and NRS-2002 were not superior to each other in predicting long-term mortality., (© 2021 American Society for Parenteral and Enteral Nutrition.)

- Abstract
Objectives: This study aimed to provide data about the role of muscle ultrasound (US) to predict sarcopenia., Methods: A total of 313 geriatric outpatients (age ≥65 y) were enrolled in the study. After a comprehensive geriatric assessment, anthropometric measurement and handgrip strength (HGS) data were obtained and a bioelectrical impedance analysis was performed. Sarcopenia was diagnosed using HGS and bioelectrical impedance analysis data. Gastrocnemius medialis (GC), rectus femoris (RF), and rectus abdominis (RA) muscle thickness as well as the RF cross-sectional area (CSA) were measured with US. The role of muscle US to predict sarcopenia was defined with a receiver operating characteristics analysis., Results: The prevalence of probable and confirmed sarcopenia were 43.8% (n = 137) and 13.4% (n = 42), respectively. All muscle US parameters had positive correlations with both HGS and the fat-free mass index. There were inverse correlations between all muscle US parameters and the five-item sarcopenia questionnaire. The RF CSA had stronger correlations with the five-item sarcopenia questionnaire, HGS, and the fat-free mass index than others. The values of GC, RF, and RA muscle thickness and the RF CSA to predict sarcopenia for women/men were 13.9/13.8 mm (area under the curve [AUC]: 0.817/0.707 mm), 13/15.5 mm (AUC: 0.760/0.736 mm), 4.3/5.2 cm
2 (AUC: 0.766/0.773 cm2 ), and 6.6/7.0 mm (AUC: 0.740/0.688 mm), respectively., Conclusions: GC, RF, and RA muscle thickness and the RF CSA all may predict sarcopenia accurately in geriatric outpatients., (Copyright © 2022 Elsevier Inc. All rights reserved.)- Published

- Abstract
Background: Insomnia is associated with depression, cognitive impairment, hypertension, myocardial infarction, stroke, metabolic syndrome and prostate cancer in the elderly. The aim of this study is to investigate the relationship between severity of insomnia and falls., Methods: This cross-sectional study was conducted in a single geriatric outpatient clinic at a university teaching hospital. Patients with active infection, who could not complete insomnia severity index (ISI) test because of cognitive impairment and who could not perform handgrip strength and timed up and go (TUG) tests were excluded from the study., Results: A total of 215 patients were included in this study. Logistic regression analysis showed that there is significant relationship between poorer TUG performance, mild insomnia, moderate insomnia, severe insomnia and falls in the elderly (odds ratio (OR) = 1.04, CI: 1.00-1.09, P = 0.041, OR = 2.43, CI: 1.22-4.85, P = 0.011, OR = 3.84, CI:1.35-10.94, P = 0.012, OR = 5.81, CI:1.00-33.72, P = 0.050)., Conclusions: In this study we showed that there is a relationship between the severity of insomnia and falls., (© 2021 Japanese Psychogeriatric Society.)
