Amaç: Sistemik tek doz Methotrexate (MTX) verilmesinin over folikül rezervi üzerine etkisinin araştırılması.Materyal ve Metot: Çalışmada toplam 20 adet Wistar Albino cinsi kullanıldı. Düzenli sikluslara sahip olduğu tespit edilen ratlar rastgele iki gruba ayrıldı. Grup I (n=10)de : İntra musküler (IM) olarak tek doz halinde 50mg/m2 MTX, Grup II (n=10)de IM olarak tek doz halinde aynı hacimde serum fizyolojik (SF) uygulandı. Son MTX dozundan sonra bir hafta süreyle tüm ratlara günlük smear takipleri yapılarak siklus düzensizlikleri olup olmadıkları araştırıldı. Tedavi sonrası üçüncü haftanın sonunda ratlar servikal dislokasyon ile sakrifiye edildi ve bilateral overleri çıkarıldı. Çıkarılan overlerden hazırlanan hemotoksilen-eozin ile boyanmış preparatlarda primordial, primer, sekonder, tersiyer folikül, korpus luteum sayıldı ve folikül rezervi hesaplandı. Fibrozis varlığı ve histiyosit infiltrasyonu araştırıldı.Bulgular: Gruplar arası karşılaştırmalarda tek doz MTX verilen grupta primer, sekonder folikül sayılarında azalma, atretik folikül, fibrozis ve histiyosit skorlarında artışlar olduğu tespit edildi. Fark anlamlı bulunmadı (p>0.05). Tedavi sonrası smear takiplerinde MTX verilen ratların bir tanesinde estrus fazı görülmedi (p>0.05). Korpus luteum ve folikül kisti MTX grubunda azalmış olarak bulundu (p>0.05).Sonuç: MTXın over folikül rezervlerinde azalmalara neden olması menapoz yaşında etkili olabilir. İnsanlardaki etkilerinin belirlenebilmesi için daha ileri düzeyde çalışmalara ihtiyaç vardır., Objective: To investigate the effects of systemic single-dose methotrexate (MTX) administration on ovarian follicle reserve. Materials and Methods: The study included a total of 20 rats of Wistar Albino species. The rats that had regular cycles were randomly allocated to two groups. Group I (n=10) was administered single-dose intramuscular (im) 50 mg/m2 MTX, while Group II (n=10) received single-dose serum physiologic at the same volume. After administration of the last MTX dose, daily smear follow-ups of all rats were made for one week and these were examined for cycle irregularities. At the end of the third week after treatment, rats were sacrified and bilateral ovaries were taken out. Primordial, primary, secondary, tertiary follicle and corpus luteum were counted in the preparations of ovarian samples stained with hematoxylin eosine. Presence of fibrosis and histiocyte infiltration was examined. Results: Inter-group comparison showed that there was a decrease in primary, secondary follicle counts and a increase atretic follicle counts, fibrosis and histiocyte infiltration scores in the group that was administered single-dose MTX. The differences were insignificant (p>0.05). It was seen in the post-treatment smear follow-ups that one rat that was given MTX did not have estrus phase (p>0.05). No difference was found between groups in terms of corpus luteum and follicle cyst (p>0.05). Conclusion: The reductions by MTX in ovarian follicle reserves may affect menopause age. Further studies are needed to determine its effects on humans.

Bu çalışmada ovaryan hiperstimülasyon sendromu (OHSS) oluşturulan ratlarda, OHSS patofizyolojisinde TRPM2 iyon kanalları ve CHRM1 aktiviteleri araştırılmıştır.Çalışmada 14 adet, 22 günlük immatür dişi Wistar Albino cinsiratın rastgele seçilen 7'sine 10 IU FSH dört gün subkutan ve beşinci gün 30 IU human koryonik gonadotropin verilerek ovaryan hiperstimülasyon oluşturuldu.. Grup 1 (n=7) 27 günlük normal, Grup 2 (n=7) 27 günlük OHSS oluşturulan grup olarak ratlar ikiye bölündü.Daha sonra tüm grupların overleri ve kan örnekleri alınıp ratlar sakrifiye edildi.Serumda VEGF, IL1, IL6, IL10, TNFα ve MDA düzeyleri,dokudaTRPM2 ve CHRM1 aktiviteleri ölçüldü.IL1 ve IL6 düzeyleri, iki grupta da benzer olup istatistiksel olarak herhangi bir farklılık izlenmedi (p>0,05). Kontrol grubu ile kıyaslandığında, OHSS grubunda IL10 (p=0,038), TNFα (p=0,007), VEGF (p=0,0017), MDA (p=0,004) düzeyleri artmış izlendi.Kontrol grubu ile kıyaslandığında, OHSS grubu over dokusunda CHRM1 (p=0.001) ve TRPM2 (p=0.001) aktiviteleri artmış izlendi.Sonuç olarak, OHSS'de çok farklı mediyatörler ve sistemler patolojiden sorumludur. TRPM2 iyon kanalları ve CHRM1 aktivitesindeki artışlar OHSS patofizyolojisine farklı bir bakış açısı oluşturmaktadır. THE ACTIVITIES OF TRPM2 ION CHANNEL AND CHRM1 IN OVARIAN HYPERSTIMULATION SYNDROME (OHSS)In this study, TRPM2 ion channels and CHRM1 activities were investigated in the pathophysiology of ovarian hyperstimulation syndrome (OHSS). 22 days old 14 immature female Wistar albino rats divided into 2 groups randomly. 25 of them received 10 IU FSH for four days subcutenously and 30 IU human chorionic gonodotropin at fifth day for augmenting ovarian hyperstimulation. Group 1 (n = 7) normal for 27 days old, Group 2 (n = 7) rats were divided into two groups as 27 days old OHSS. Ovaries and blood samples were taken from all groups and rats were sacrificed. TRPM2 and CHRM1 activity in tissues and VEGF, IL1, IL6, IL10, TNFα , MDA levels in blood were measured.IL1 and IL6 levels were similar in two groups and no statistically significant difference was observed (p>0,05).When compared with the Control group, IL10 (p=0,038), TNFα (p=0,007), VEGF (p=0,0017) and MDA (p=0,004) levels were increased in the OHSS group.When compared with the Control group, CHRM1 (p=0,001) and TRPM2(p=0,001) levels were increased in the OHSS group's ovarian tissue.As a result, many different mediators and systems are responsible for pathology of OHSS. Increases in TRPM2 ion channels and CHRM1 activity provide a different perspective on the pathophysiology of OHSS. 72

Over transplantasyonunda çözülmemiş en önemli konulardan birisi iskemi re-perfüzyon hasarının önlenmesidir.Bu nedenle, serbest radikal üretimini azaltmak üzere antioksidanlar uygulanması over naklinden sonra iskemi ve reperfüzyon hasarının sonuçlarına karşı önemli bir ilaç hedefi olarak kabul edilebilir.Bu çalışmada over transplantasyonunda N-asetilsistein ve benfotiamin kullanılarak transplantasyon sonrası oluşacak hasara karşı benfotiamin ve N-asetilsistein etkileri araştırıldı.N-asetil sistein doğal bir aminoasit olan L- Sisteinin N-asetillenmiş türüdür. Asetil sistein mukolitik bir ajan ve sistein proglutatyan yapısında olan serbest radikal tutucu endojen bir antioksidandır. Oksidatif streste glutatyon havuzunu bir glutatyan prekürsörü olarak besler, glutatyon redoks siklusu, endoteli korumada iyi bir defans sistemi sağlar. Benfotiamin Vitamin B1'in yağda çözünen halidir. Benfotiaminin reaktif oksijen türleri üzerinde baskılayıcı olduğu bazı çalışmalarda gösterilmiştir. Çalışmada, 28 adet 12-14 haftalık Wistar albino cinsi dişi sıçanlar kullanıldı. Deney hayvanları 4 gruba ayrıldı. . Grup I: Kontrol grubu olarak kullanıldı Grup II: Transplantasyon grubu olarak kullanıldı Grup III: Transplantasyon grubuna transplantasyonda 1 gün once ve sonrasında 3 hafta boyunca 75 mg/kg/gün benfotiamin oral gavaj yoluyla uygulandı Grup IV: Transplantasyon grubuna transplantasyondan 1 gün once ve sonrasında 7 gün boyunca 150 mg/kg/gün N-asetilsistein intraperitoneal uygulandı.Deney süresi sonunda tüm gruplardaki sıçanlar anestezi altında dekapite edildi. Dekapitasyonun ardından sıçanların over dokuları hızla çıkarılıp uygun fiksatiflerle tespit edilip ardından histolojik takip serilerinden geçirilip parafin bloklara gömüldü. Parafin bloklardan alınan doku kesitlerine Masson-Trikrom boyası yapılarak gruplar arası histopatolojik farklılıklar incelendi. Ayrıca bu kesitlere TUNEL tekniği uygulanarak apoptotik hücreler tespit edildi. Ayrıca dokularda Toplam Antioksidan Durum (TAS)-Toplam Oksidan Durum (TOS) aktivitesine bakılacağından dokular çalışma gününe kadar -80 °C'de saklandı. Over dokusunda kontrol grubu ile kıyaslandığında transplantasyon yapılan grupta apopitotik hücreler, fibrozis, oksidatif hasar, inflamatuar hücre düzeyinde belirgin artış izlendi, transplantasyon yapılan grupla kıyaslandığında ise benfotiamin ve NAC verilen gruplarda bu değişikliklerde anlamlı bir azalma izlendi. Over rezervi açısından kontrol grubu ile kıyaslandığında tüm gruplarda primordial folikül sayısı azalmıştı tedavi grupları arasında anlamlı fark yoktu, sekonder, primer folikül, corpus luteum açısından gruplar arasında fark yoktu. Sonuç olarak; Transplantasyon, over dokusunda iskemi-reperfüzyona bağlı oksidatif hasar sonucu apopitozis, nekroz, fibrozisde artışa neden oldu. Benfotiamin ve NAC bu hasarı azaltmada eşit derecede ve etkili bulundu.Anahtar kelimeler: Over transplantasyonu, N-asetilsistein, Benfotiamin One of the most important unresolved issues in the ovary transplantation is prevention of ischemia reperfusion injury. Therefore, application of antioxidants to reduce free radical generation after ovarian transplant can be regarded as an important drug target against the consequences of ischemia and reperfusion injury. In this study, using N-acetylcysteine and benfotiamine over tranplantation effect of N-acetylcysteine and benfotiamine were investigated against injury induced by transplantation.N-acetylcysteine, is a N-acetylated species of natural amino acid L-cysteine. Acetylcysteine is a mucolytic agent and endogenous antioxidants, free radical scavengers the structure of sisteinproglutaty. As a glutathione precursor feeds glutathione pool during oxidative stress, glutathione redox cycle, provides a good defense system in the endothelium protection. Benfotiamine is a fat-soluble form of Vitamin B1. Benfotiamine as inhibitor on reactive oxygen species it has been shown in some studies.In the study, total number of 28 Wistar Albino 12-14 week old female rats used and were divided into 4 groups. Group I was used as the control group. Group II was used as the transplant group. Group III 1 day before and after the transplantation for 3 weeks was administered by oral gavage 75 mg / kg / day benfotiamine. Grup IV 1 day before and after the transplantation for 7 days 150 mg/kg/day N-acetylcysteine was administered intraperitoneally.The all group rats were decapitated under anesthesia at the end of the experimental period. After decapitation ovarian tissues of the rats removed quickly, then detected by appropriate fixative passed through the histologic follow-up series and embedded in parafin wax. The tissue sections from paraffin blocks Masson trichrome stain by applying analyzed histopathological differences between the groups. In addion to apoptotic cells were detected by applying the TUNEL technique in this section. Also with the aim look at the total antioxidant status (TAS) -Total oxidant status (TOS) activities in tissues, tissues were stored at -80 ° C until the working day. When compared with the control group in the transplant group was observed apoptotic cells in ovarian tissue, fibrosis, oxidative damage, a significant increase in levels of inflammatory cells. When benfotiamine and NAC-treated group compared with transplantation group, observed by a significant decrease at these changings. In terms of ovarian reserve in all groups compared with the control group, the number of primordial follicles was reduced but no significant difference between treatment groups. There was no difference between groups in terms secondary and primary follicles, corpus luteum.As a result; the ovarian transplantation caused increased apoptosis, necrosis, fibrosis as a result of oxidative damage caused by ischemia-reperfusion. Benfotiamine and NAC applications were found equally and effectively reduce this damage. Keywords: N-acetylcysteine, Benfothiamin, Ovarian transplantation 76

- Abstract
Background/aim: Ovarian hyperstimulation syndrome (OHSS) is a complication of ovarian stimulation with increased vascular endothelial growth factor (VEGF) and vascular permeability in the ovarian tissue. Transient receptor potential melastatin 2 (TRPM2) is known to be associated with angiogenesis and vascular permeability. In this experimental study, we aimed to investigate the activity of TRPM2 in the development of OHSS., Materials and Methods: Fourteen immature female rats were divided into two groups. Group 1 was the control group, and Group 2 was the OHSS group that was exposed to 10 IU of subcutaneous application of FSH for four days and 30 IU of human chorionic gonadotropin (hCG) on the 5th day. At the end of the experiment, the ovaries were removed. The right ovarian tissues were stored in 10% formol for histopathological and immunohistochemical examination. The left ovarian tissues were stored at –80 °C for biochemical examinations. VEGF, tumor necrosis factor-alpha (TNF‐α) and malondialdehyde (MDA) levels were measured in the ovarian tissue. Congestion, edema, apoptosis and TRPM2 immunoreactivity were evaluated., Results: There was a significant increase in ovarian weight in the OHSS group compared to the control group. There was a significant increase in congestion, edema, apoptosis and TRPM2 immunoreactivity in the OHSS group. A significant increase in tissue levels of VEGF, TNF‐α and MDA was also found in the OHSS group compared to the control group., Conclusion: As a result of our experiment, it was found that increased TRPM2 immunoreactivity on hyperstimulated rat ovary may be the reason or result of edema and congestion. Further studies are needed to discuss our results., Competing Interests: The authors declare that they have no conflicts of interest., (This work is licensed under a Creative Commons Attribution 4.0 International License.)

Background/aim: The purpose of this study was toinvestigate the effects of 10% povidone–iodine (PI) sclerotherapyon ovarian cyst diameter through an experimental study., Materials and Methods: To be able to create ovarian cysts, right unilateral salpingectomy was performed on 20 Wistar albino rats. One month after the operation, the abdomens of all rats were reopened. Sixteen rats with macroscopic ovarian cysts were divided randomly into 2 groups consisting of 8 rats. Group 1 (G1): the cyst content was only aspirated. Group 2 (G2): the ovarian cyst was aspirated and then the cystic cavity was irrigated with PI. Abdomens of all rats were closed and 1 month later they were reopened. Tissues of the right ovaries of the rats were embedded in paraffin blocks for histopathological examination. Follicle count, fibrosis, and congestion were evaluated under a light microscope., Results: For G1, there was no difference in cyst diameters before and after aspiration. In G2, a decrease was observed in cyst diameter. There was no difference in ovarian reserve between the 2 groups. When compared with G1, an increase in fibrosis and congestion was determined in G2., Conclusion: Sclerotherapyinto the ovarian cyst for a 5-min period using 10% PI reduces cyst diameter without any change in ovarian reserve., (This work is licensed under a Creative Commons Attribution 4.0 International License)

- Abstract
Background/aim: This study compared TRPM2 and TRPM7 ion channel gene expression and immunohistochemical staining in endometrial hyperplasia and endometrium adenocarcinoma., Materials and Methods: Sections were taken from paraffin blocks of 120 patients who were divided into 6 groups as follows: G1 (n = 20), proliferative endometrium (PE); G2 (n = 20), EH without atypia; G3 (n = 20), EH with atypia; G4 (n = 20), stage 1A, grade 1 EC; G5 (n = 20), stage 1A, grade 2 EC; and G6 (n = 20), stage 1A, grade 3 EC. TRPM2 and TRPM7 genes were analyzed with qRT-PCR in paraffin-embedded tissue samples. Under light microscopy, TRPM2 and TRPM7 immunostaining scores of the samples taken from polylysine slides were evaluated., Results: Compared to G1, TRPM2 mRNA gene expression was significantly downregulated in G3 and G5. TRPM2 immunoreactivity scores were similar in all groups. TRPM7 mRNA gene expression was significantly downregulated in G2, G3, and G6 when compared to G1. TRPM7 immunoreactivity scores were similar in G1, G2, and G3, but significantly decreased in G4, G5, and G6, Conclusion: Reduction in TRPM7 ion channel activity may be a progression marker for endometrial hyperplasia regardless of the atypical criteria.
