Aim: The aim of this study is to see the development of balance ability with easy-to- apply training programs prepared for female basketball players competing in amateur leagues. Material and Method: In this study, 12 active players of Giresun University Women's Basketball team, who fought in ENTL in the 2018-2019 season, who did not have neurological disease, vestibular visual discomfort or serious lower limb disability in the last 6 months were included. Balance training has been prepared for the players for 12 weeks. Before starting the exercise program specially prepared for the players and at the end of every 4 weeks, static balance abilities, flamingo balance test and dynamic balance abilities were taken and recorded both dominant and non-dominant side measurements with star balance test. Results: After the exercises and measurements, it is seen that the static balance ability and dynamic balance ability showed improvement compared to the previous measurement. When the results are examined, it is seen that p value is approximately 0,000 in all athletes. This value, which is below the significance level we selected (p = 0.05), clearly shows that each measurement value of the athletes has improved compared to the previous one. Conclusion: It is observed that static and dynamic balance abilities can be developed with easy-to-apply balance training prepared for female athletes.

WOS: 000425136100006, The effects of chronic morphine administration on the rat cerebellum and silver stained nucleolus organizer regions in Purkinje cells were investigated by means of histological, histochemical and histometrical techniques. Thirty-two young (30-32 days of age) Wistar rats (equal numbers of both genders) were randomly divided into 2 groups, as control and morphine-treated, each having equal numbers of both genders, a total of 16 animals. The control animals were injected subcutaneously with 1mL/kg physiological saline, and the morphine-treated rats received 5 mg/kg morphine hydrochloride subcutaneously at daily intervals for 30 days. The thickness of the molecular and granular layers of the cerebellum, the diameters of the nuclei and nucleoli of cerebellar Purkinje neurones, and the number and size of the silver staining nucleolus organizer regions of the Purkinje cell nuclei were determined histomorphometrically. The morphine administration caused slight histological changes in the cerebellum. The molecular layer thickness of the cerebellum was significantly (P

Duplication of the vas deferens is a rare congenital anomaly, and it can be complete or partial. It is usually discovered as an incidental finding during elective operations stich as a vasectomy, herniorrhaphy or varicocelectomy. During the educational dissection of a 72-year-old cadaver, a complete vas deferens duplication was observed on the left. If a vas deferens duplication is not appropriately diagnosed, it can result in surgical complications or an unsuccessful vasectomy. Screening for renal agenesis should be performed in patients with duplication of the vas deferens.

La arteria carotida externa (ACE) es la principal arteria de la cabeza y de la region del cuello. La bifurcacion carotidea (BC) es uno de los lugares donde las placas ateroscleroticas son mas frecuentes. El procedimiento quirurgico para tratar estas placas que causan el accidente vascular cerebral (AVC) es la endarterectomia carotidea. En este procedimiento quirurgico, el conocimiento de los cursos anatomicos y variaciones de la arteria carotida aumenta el rendimiento de la cirugia. El objetivo de nuestro estudio fue presentar el trayecto, localizacion y variacion de la ACE y sus ramas. El estudio se realizo mediante angiografia multidetector por tomografia computarizada de la ACE de 50 hombres y 50 mujeres, totalizando 200 ACE (100 derechas y 100 izquierdas). Se evaluaron el diametro interior de la arteria carotida comun (ACC) y la ACE. Se determino la ubicacion de la BC y se midio la distancia vertical hasta el gonion. Se observo que la arteria tiroidea superior (ATS) se origino desde la ACC, la BC y la ACA. Las distancias verticales entre la BC, y las arterias tiroidea superior, lingual (AL), facial (AF) y occipital (AO) fueron medidas. La ACE y sus ramas se registraron. Creemos que la evaluacion morfometrica de la ACE puede comprender grupos de control de las enfermedades relacionadas con el diametro de los vasos, y estos datos pueden ser utilizados como referencia clinica y quirurgica. El conocimiento de los detalles anatomicos y variaciones es de vital importancia para evitar complicaciones imprevisibles en la cirugia.

Vascular structures are in greater danger during lumbar surgery. The purpose of this study is to describe the morphology of the inferior vena cava (IVC) related to the lumbar vertebra and aortic bifurcation (AB) and assessing the role of demographic values in these relations to decrease the risk of complications in the surgical interventions. The study was performed on Multidetector Computed Tomography (MDCT) images of 100 male and 100 female cases with an age range from 50 to 84 years. The morphometric values of the IVC obtained from the coronal, sagittal and the axial reformatted images were measured and compared with the demographic values. The distance from the IVC to the 1st lumbar vertebra (L1) and 2nd lumbar vertebra (L2) were measured as (26.5 mm and 18.1 mm) in males and (21.1 mm and 14.2 mm) in females with a high level of significance between genders; the distance from the IVC to the iliocaval confluence (IC), 3rd lumbar vertebra (L3) and 4rd lumbar vertebra (L4) were measured as (6.5 mm, 10.5 mm and 6.9 mm) in males and (4.9 mm, 9.1 mm and 5.5 mm) in females with significance between genders. The level of the IC was detected 46 % of males, 39 % of females at the level of lower third of L4. The vertical distance between the IC and the AB was measured and negative correlation between genders based on age was detected. Demographic values are important to consider the relationship of the IVC, the lumbar vertebra and the AB. The IVC was located further from the lumbar vertebra in males compared to females. Age increase played role in the approaching of the AB and the IC to each other in both gender and the IC to the promontory level in males.

Objective It was aimed to research the morphometric development of the nasal cavity with dissection and radiological scanning methods and to detect anatomical variations. Design Retrospective study. Setting Departments of Anatomy and Radiology, Meram Medical Faculty, Selcuk University. Patients Dissection stage was performed on 80 spontaneously aborted fetuses (40 males and 40 females) (63 second trimesters and 17 third trimesters) between 13 and 40 weeks of gestation. Radiological scanning stage was carried out on 40 spontaneously aborted fetuses (19 males and 21 females) (12 second trimesters and 28 third trimesters) with multi-detector computed tomography. Methodology One hundred and sixty nasal cavities and related structures were examined by means of bilateral dissection. Reference images were obtained in the axial plane with 3-mm collimation using multi-detector computed tomography (MDCT; Sensation 64, Siemens, Erlangen, Germany). These reference images were sent to the workstation (Leonardo, Siemens, Germany) and three-dimensional (axial, sagittal, and coronal) reformatted images with 1 mm thickness were obtained via multiplanar imaging method. Results In the dissected fetuses 16 suprema nasal conchae were determined. Six (15%) NSDs (four towards the left and two towards the right) were detected on radiological sections. The angle between the virtual line from sphenoidal sinus ostium through limen nasi and the horizontal plane was 32.72 ± 3.3° on average. Conclusion It was thought that some anatomic variations (e.g. suprema nasal concha, nasal septum deviation) occur in the fetal period; however, other certain differences (e.g. Onodi, Haller, and Agger nasi cells, concha bullosa) might be with effects of environmental factors (trauma and chronic infections) in postnatal period.

The course and branches of the musculocutaneous nerve (MCN) were dissected in 140 human fetal arms. The MCN entered the superior, middle, and inferior part of coracobrachialis in 43%, 37%, and 17% of arms, respectively, and the remaining 3% did not pierce coracobrachialis. The motor branches to biceps were classified as follows: Type 1 (83.6%): a single branch that bifurcated to supply the two heads of biceps; Type 2 (14.3%): two separate branches each innervating one head of biceps; Type 3 (2.1%): a single branch that bifurcated to supply each head of biceps plus an additional branch that innervated the distal part of biceps. The motor branches to brachialis were classified as follows: Type 1 (93.6%): a single branch to brachialis; Type 2 (6.4%): a single branch that bifurcated into two branches both supplying brachialis. Communications between the MCN and the median nerve (MN) were observed in 10% of specimens, of which three types (A, B, C) could be identified depending on their origin and union. In the most frequently observed type (B, 50% of cases) the communicating branch arose from the proximal part of the MCN and joined the MN in the middle or distal part of arm. The data presented here will be of use to surgeons, especially pediatric surgeons who undertake surgical procedures in the axilla and arm.

We aimed to evaluate whether bypass of the external carotid artery (ECA) to the middle cerebral artery (MCA) can be established by a short saphenous vein graft in order to increase the anastomosis patency. The method was performed to ten adult cadaver sides. We described a modified technique for bypass of the ECA to the M2 segment of MCA. The diameters of the vessels and graft length were measured by using an electronic micrometer. The mean diameter of the superior, middle, and inferior trunks of the MCA with trifurcation were 1.7 +/- 0.15, 2.2 +/- 0.25, and 2.0 +/- 0.2 mm, respectively, whereas the mean diameter of the superior and inferior trunks of the MCA with bifurcation were 2.1 +/- 0.2 and 2.3 +/- 0.3 mm, respectively. The mean diameter of the ECA was 3.75 +/- 0.4 mm. The mean length of the saphenous vein graft was 71.5 +/- 3.9 mm. The high-flow ECA to proximal MCA bypass using a short venous graft can supply enough blood flow to establish cerebral revascularization with a straighter route.

Conclusions. Our results support the proposition that bypass between the external carotid artery (ECA) and proximal posterior cerebral artery (PCA) can be achieved by using a short saphenous venous graft. The diameters of the ECA and vein graft may provide an increased blood flow with a straighter course. This technique may be helpful for management of patients with vertebrobasilar insufficiency or those requiring a high volume blood flow to the posterior circulation. Objectives. We aimed to describe a modified technique using a short saphenous vein graft for bypass between the ECA and the PCA in order to use a small length of graft material and increase the patency of the anastomosis. Materials and methods. Ten sides of five cadavers were dissected bilaterally. After a frontotemporal craniotomy and zygomatic arch osteotomy, the middle cranial fossa was exposed. A hole located approximately 2/3 cm posterolateral to the foramen rotundum was created extradurally. The sylvian fissure and the interpedincular and ambient cisterns were opened. The proximal P2 segment of the PCA was identified. The ECA was found through a cervical incision. A short interposition saphenous vein graft was conducted to pass just behind the ramus mandible to the infratemporal fossa. The bypass between the ECA and P2 segment of the PCA was performed by using a short saphenous vein graft. The diameters of the ECA, P2 segment of PCA and both ends of the saphenous vein graft and its length were measured using an electronic micrometer. Results. The mean cross-clamping time of the PCA was 10.49 /1.8 min. The mean diameters of the P2 segment of the PCA and ECA were 2.29 /0.15 mm and 3.839 /0.28 mm, respectively. The mean length of the saphenous vein graft was 88.89 /3.8 mm.

Variations in the position of the bifurcation of the common carotid artery (CCA) and the origin or branching pattern of the external carotid artery (ECA) are well known and documented. In this study, the bifurcation levels of the CCA and origin variations of the branches of the ECA have been extensively investigated in human fetuses. Bilaterally, 40 carotid bifurcations and 40 ECA and their branches have been examined. A latex solution, which had been diluted with water at a ratio of 25% and colored with red India ink, was injected into the aortic arch. Fetuses were kept at room temperature for 24 h before the ECA and its branches were dissected under the microsurgery microscope. Cases of variation were determined and photographed. The bifurcation level of the CCA was determined to be 55% at the C3 level, 35% at the C4 level, 10% at the C5 level on the right side and 60% at the C3 level, 40% at the C4 level on left side. The distribution of the ECA trunks was determined as follows: A linguofacial trunk was present in 20% of the cases, a thyrolingual trunk in 2.5%, a thyrolinguofacial trunk in 2.5% and an occipitoauricular trunk in 12.5%. Beyond this the ascending pharyngeal artery (APA) was observed in one fetus to originate from the internal carotid artery (ICA). Knowledge of variations in the origin and course of the ECA and its branches is of great importance in surgery and radiological examinations.

We investigated the origin, localizations and anatomic variations of the renal artery (RA) in human fetuses with the aim of determining the distribution of these variations according to lateralization and gender. In total, 90 fetuses of spontaneous abortion (45 males, 45 females) with no congenital malformations were included to the study. The abdominal aorta and its branches were dissected after latex solution colored with red ink had been injected into the vessels from the thoracic aorta. In all, 180 RA dissections were performed bilaterally in 90 cases and the anatomic variations were photographed. Right and left RAs were found to originate from the following levels according to the columna vertebralis, respectively: 3.8% and 1.9% lower T12, 67.3% and 25.0% upper L1, 9.6% and 28.8% mid L1, 15.3% and 40.3 lower L1, 3.8% and 3.8% upper 1/3 part of L2 vertebra. The right RA originated from the lateral part and anterolateral wall of the abdominal aorta in 73.0% and 26.9% of cases while the lateral and anterolateral wall origin percentages of left RA were 90.3% and 9.6%, respectively. The origin site of the right RA from the abdominal aorta was superior to, at the same level with, and inferior to that of the left RA in 53.8%, 34.6% and 11.5% of the cases, respectively. There were no variations in 75% of the cases whereas the remaining 25% had several variation patterns. The presented morphological results are as follows: A single hilar artery in 75% of the cases, double hilar arteries in 11.1%, an inferior polar artery in 10.5%, and a superior polar artery in 3.3% of specimens studied. Anatomical variations were observed more frequently among male fetuses and on the right side. Knowledge of RA variations is important for surgeons in performing many procedures and may help to avoid clinical complications, especially, during radiological examination and/or surgical approaches in the abdominal region.

Lumbar arteries are in series with the posterior intercostal arteries. The aim of this study has been to investigate the morphometric data on the abdominal aorta of the human fetus and define different types of origin variations of the lumbar artery. Initially, the latex solution colored with red ink was injected into the thoracic aorta. The abdominal aorta and its branches were dissected and examined bilaterally in 120 fetuses (ranging between 16 and 32 post-menstrual weeks) and the anatomic variations recorded. Fourteen fetuses with variations were studied and photographed. The origins and morphologic variations of the lumbar arteries were defined and classified. The morphological relationship of the lumbar arteries to the abdominal aorta and the length and width (diameter) of the vessels were investigated by performing measurements using a digital calliper (mm). The frequency and the types of the different variations determined in the present study have been listed. Abdominal aortic branches and Lumbar artery aneurysms are rare lesions with potentially life-threatening consequences and they are difficult to access anatomically and formidable to manage operatively. During the performance of conventional or open surgical replacement of an abdominal aortic aneurysm with prosthetic grafts, the surgeon needs precise knowledge of the anatomy of the abdominal aortic branches and immediate retroperitoneal structures. The variations on the lumbar arteries may have clinical importance. When this region is under diagnostic and/or surgical investigation using computed tomography scan or diagnostic angiography, the possibility of these variations should be take into consideration to avoid complications.

Background: Nasal bone aplasia and hypoplasia have been reported on fetuses with aneuploidy. Trisomy 21 is one of the most common chromosomal abnormality detected in new-borns. The purpose of our study is to obtain data of some face parameters in Turkish fetal population and to contribute creation of reference ranges that may be used for prenatal diagnosis.Methods: This study was performed in 66 spontaneously aborted fetuses (47 second trimester and 19 third trimester) (28 male and 38 female) with no detectable external pathology or anomalies. Measurements were designed as nasal bone length (NBL), nose length (NL), nose width (NW), nostril width (NsW), intraocular distance (IOD), innercanthal distance (ICD), outercanthal distance (OCD), orbital diameter (OD), biparietal diameter (BPD).Results: In comparison between genders, ICD and BPD averages were found significantly higher in male fetuses than female fetuses (P

The use of a saphenous vein graft for bypass of the maxillary artery (MA) to the supraclinoid internal carotid artery (ICA) in internal carotid occlusions is investigated. Five adult cadaver sides were used. Dissection required zygomatic arch osteotomy and a pterional craniotomy with extensive removal of the floor of the middle cranial fossa. The MA was found easily medial to infratemporal crest. The clinoidal segment of the ICA was exposed with the removal of the anterior clinoid process intradurally. The bypass graft was 4 to 5 cm long and was sutured end-to-end to the MA and end-to-side to the supraclinoid ICA. When high blood flow is needed in cases with ICA occlusion, such a bypass may be an alternative to superficial temporal (STA)-to-middle cerebral artery (MCA) bypass as well as to common carotid-to-MCA or-ICA bypass, which needs a long vein graft. This type of bypass will provide the opportunity to clip the ICA proximal to the origin of ophthalmic artery, which may inhibit distal embolization.

La escapula tiene tres margenes y tres angulos, y se encuentra en la region posterolateral del torax. Una de las estructuras anatomicas de la escapula es la incisura supraescapular situada medial a la base del proceso coracoides. La incisura supraescapular puede tener diferentes formas y profundidad. Esta rodeada por el ligamento escapular transverso, un ligamento corto y fuerte. Con esta estructura, crea un pasaje osteofibroso por el cual pasa el nervio supraescapular. Se ha reportado que esta estructura osteofibrosa se puede osificar completa o parcialmente. Todas las lesiones de los nervios ocurren en su trayecto como resultado de la exposicion a compresion, tension y flexion, lo que se denomina neuropatia por atrapamiento. El nervio supraescapular puede estar expuesto a compresion al pasar por la incisura supraescapular, generando neuropatia por atrapamiento. Su etiologia puede ser por traumatismo directo, microtraumatismo repetitivo y lesiones compresivas progresivas. Una incisura supraescapular de forma oval puede ser un factor predisponente para la neuropatia por atrapamiento. En un estudio retrospectivo realizado en la Universidad Necmettin Erbakan, Facultad de Medicina de Meram, Departamento de archivo de Radiologia, se observo la imagen de un varon de 68 anos con variacion en la incisura supraescapular derecha, la cual se transformo en un foramen por un puente oseo. Los diametros del foramen fueron 5,27 mm transversales y 6,48 mm verticales. Creemos que el conocimiento detallado de la incisura supraescapular es necesario en el diagnostico y posible curso de dolor del hombro, debido al atrapamiento del nervio supraescapular en la incisura y la posible paralisis nerviosa, dando una guia a los clinicos en las practicas quirurgicas.

WOS: 000300031600011, PubMed: 22274973, AIM: The topography of the superficial peroneal nerve (SPN) and its terminal branches were studied, with the aim of providing further anatomical details for leg and foot in the Turkish newborn fetuses. MATERIAL and METHODS: Limbs from twenty newborn cadavers were dissected. The course of the SPN on the leg and its terminal branches on the foot were investigated. RESULTS: The SPN was lateral (75%), anterior (15%), or branched in both areas (10%) of the cases. The SPN in the dorsum of the feet branched further into medial dorsal cutaneous nerve (MDCn) and intermediate dorsal cutaneous nerve (IDCn). In 82.5% of the cases the MDCn and the IDCn split into three and two branches, respectively. In 10% of the cases, the MDCn gave off three, and the IDCn one terminal branches. In 7.5% of the cases, the MDCn had three while the IDCn had two branches that communicated with the lateral dorsal cutaneous nerve. CONCLUSION: The course of SPN on the anterolateral surface of the leg and its terminal branches on the dorsal surface of the foot were quite different. This unusual variant location will enable the surgeon to find and preserve the SPN and its terminal branches.

WOS: 000283274500049, Variations of vessels and nerves in the left neck side, of 65 year old male cadaver, during the routine dissections, were detected. It was observed that the linguofacial trunk originated from external carotid artery and that the ascending pharyngeal artery originated from the occipital artery. It was determined that after the laryngeopharyngeales rami originated from the superior cervical ganglion, the branch wound around the origin of the superior thyroid artery. As an additional variation, the internal jugular vein divided. The cervical ansa and the inferior belly of the omohyoid muscle passed through the parts of the vein. We think that these type of variation can entail important difficulties during radiologic and surgical procedures of the neck region. To know these anatomical variations, is important for the anatomist and surgeons.

We aimed to investigate the effects of weak extremely low frequency electromagnetic fields (ELF-EMFs) on the nucleus size, the silver staining nucleolar organizer regions (AgNORs), the frequency of micro nucleated peripheral blood lymphocytes (MPBLs) and the micro nucleated polychromatic erythrocytes (MPCEs).One hundred and twenty Swiss albino mice were equally divided into 6 groups. The study groups were exposed to 1, 2, 3, 4 and 5 microT 50 Hz-EMFs for 40 days. Micronucleus number (MN) per PBL was determined..ELF-EMF exposure caused a nonlinear decline of nucleus area. A sharp drop occurred in AgNOR area of 1 microT group, and following it gained an insignificantly higher level than that of the control group. The field did not change mean AgNOR numbers per nucleus of the groups. Relative AgNOR area had the highest level in 1 microT-exposure group, and the level was quite similar to that of the 5 microT-exposure group. The remaining groups had significantly lower values quite similar to that of the control level. The field exposure at any intensity did not affect significantly the frequency of either MPBLs or MPCEs. The number of MN per PBL in the 4 and 5 microT-exposure groups were significantly higher than those of the lower intensity exposure groups. The males in 4 microT-exposure group displayed the highest MN number per PBL, whereas values changed in a nonlinear manner.The results of the present study suggest that/=5 microT intensities of 50 Hz EMFs did not cause genotoxic effect on the mouse.

To determine the effects of very weak, extremely low frequency (50 Hz) electromagnetic field (ELF-EMF) on the relative spleen weight, lymphoid organ histology, peripheral blood leukocyte and alpha-naphthyl acetate esterase positive (ANAE- positive) lymphocyte percentages of the mouse.The study was carried out in Scientific Research and Application Center of Selcuk University, Konya, Turkey in 2005. A total of 120 Swiss albino mice were divided into 6 groups (20 in each group). The experimental animals were exposed to 1, 2, 3, 4 and 5 microT flux intensities (rms) of EMF at 50 Hz for 40 days.In the exposure groups with 20 animals, the body weight (BW) increased gradually in higher field intensities and reached at peak level in the 4 microT, and then slightly decreased. The relative spleen weight (% of the BW) was not affected. The ELF-EMF treatment did not cause any significant change in lymphocyte, monocyte and ANAE-positive lymphocyte ratios, whereas percentages of neutrophils and basophiles changed non-linearly. Any change in the lymphoid organ histology, which is attributable to the field effect, was not observed in the exposure groups.Extremely low frequency-EMF exposure with the flux intensities between 1-5 microT for 40 days did not cause any effect on the relative spleen weight, lymphoid organ histology, leukocyte and ANAE-positive lymphocyte percentages of the mouse.

To investigate the morphologic structures and developmental anomalies of the thyroid gland in human fetuses.This study performed in the Department of Anatomy, Meram Faculty of Medicine between February and April in 2002. Fetuses were obtained from the Gynecology Department of the Meram Faculty of Medicine, Selcuk University, and Dr. Faruk Sukan Maternity Hospital (Konya, Turkey). Sixty spontaneously aborted fetuses (30 boys and 30 girls) between the ages of 13.5th and 32.5th weeks, which had no detectable anomalies, were evaluated. The gland was dissected under the microscope. The location of the gland was determined according to the tracheal ring levels and laryngeal cartilage levels. The length, width and thickness of both lobes and isthmus of the gland were measured and then, the developmental anomalies were noted. The obtained data were statistically analyzed by Least Squares in variant analysis.Although there was no significant difference regarding to the gender for all parameters except in width of the right lobe (p0.05), difference in the length and width of lobes and the length of isthmus between trimesters was significant (p0.05). All measured parameters were increasing with advancing gestational age. The pyramidal lobe was observed in 18.3% of the cases.Normal dimensions and developmental anomalies of the fetal thyroid, which was shown in this study, may provide useful information for the prenatal diagnosis and in-utero treatment of thyroid dysfunctions.

WOS: 000237956600007, PubMed: 16880900, We evaluated the use of a bypass between the middle meningeal artery (MMA) and P2 segment of the posterior cerebral artery (PCA) as an alternative to an external carotid artery (ECA-to-PCA) anastomosis. Five adult cadaveric heads (10 sides) were used. After a temporal craniotomy and zygomatic arch osteotomy were performed, the dura of the floor of the middle cranial fossa was separated and elevated. The MMA was dissected away from the dura until the foramen spinosum was reached. Intradurally, the carotid and sylvian cisterns were opened. After the temporal lobe was retracted, the interpeduncular and ambient cisterns were opened and the P2 segment of the PCA was exposed. The MMA trunk was transsected just before the bifurcation of its anterior and posterior branches where it passes inside the dura and over the foramen spinosum. It was anastomosed end to side with the P2 segment of the PCA. The mean caliber of the MMA trunk before its bifurcation was 2.1 +/- 0.25 mm, and the mean caliber of the P2 was 2.2 +/- 0.2 mm. The mean length of the MMA used to perform the bypass was 32 +/- 4.1 mm, and the mean length of the MMA trunk was 39.5 +/- 4.4 mm. This bypass procedure is simpler to perform than an ECA-to-P2 revascularization using long grafts. The caliber and length of the MMA trunk are suitable to provide sufficient blood flow. Furthermore, the course of the bypass is straight.

Summary The hepatic, splenic and left gastric arteries are considered as the “main classic branches” of the coeliac trunk. During the routine dissections in the laboratory of the Anatomy Department in a 62-year-old male cadaver, a rare variation, a coeliacomesenteric trunk was observed. This trunk gave rise to the left gastric, the common hepatic, the splenic, the left gastro-epiploic, the right and left inferior phrenic arteries. The developmental and clinical significance of this anomalous vessel is discussed.

In this study we aimed to investigate the normal developmental pattern of the human fetal heart in second and third trimester, and to evaluate the correlation of the values with the gestational age (GA).Seventy spontaneously aborted human fetuses with no external malformations were investigated and 11 parameters from each were assessed. The relationship of these parameters with the GA was evaluated by linear regression and correlation analyses using statistical methods. In addition, the values were compared to the gender and sides of the heart using Student t-test. This study was performed at the Department of Anatomy, Meram Medical Faculty, Selcuk University, Konya, Turkey, during the period from 2000 to 2004.There was a statistically significant linear relationship between the heart wall thicknesses, the development of the valves of the heart and GA. The mean values of the right side of the heart were found to be higher than those of the left side, and differences were statistically significant (p0.05). Although, most of the parameters were found to be higher in females, only 2 of them were statistically significant. All parameters of the cardiac valves measured were significantly higher in the second trimester. There was no difference regarding the correlation ratio of the trimesters between the pulmonary valve diameter and GA. The measurement of the cardiac valves did not show any differences regarding the gender.This study presents the normal values of the development of the fetal heart in second and third trimester that may provide useful background information for clinical approaches.

Testicular arterial anatomy has been well studied because of its importance in testicular physiology, as well as testicular and renal surgery. In contrast to classical anatomical descriptions, it may originate from the suprarenal or lumbar arteries or a high-positioned origin, course behind the inferior vena cava or be doubled or arise from an inferior polar renal artery. Different developmental patterns as variations in relation to origin, course and number of the renal and gonadal arteries have been reported and discussed. This study was performed on 90 spontaneously aborted fetuses obtained from two different hospitals in Konya. The study was carried out on the testicular or ovarian arteries of fetuses fixed by immersion in 10% formalin. In all, 180 gonadal arteries were studied and 16 of them were found to have variations in their origin (8.8%). The variations of the gonadal artery origins could be classified into four types. The gonadal artery variations were more commonly found in male than the female fetuses and on the right side rather than the left. In the present study, it is clear that these variations are important not only from the developmental point of view or research interest, but they also may explain some pathological conditions. Knowledge of these variations may help to avoid the clinical complications especially during radiological examinations and/or surgical approaches in this region.

Background: Proximal ulnar-nerve lesions have an unfavorable prognosis. The goal of the present study was to evaluate the feasibility of selective restoration of motor function of the ulnar nerve by the transfer of the anterior interosseous nerve or one of its branches to the motor branch of the ulnar nerve. Methods: Ten cadaveric arms were used in the present study. The ulnar nerve and its motor and sensory branches as well as the anterior interosseous nerve and its branches were dissected. The widths of the motor branch of the ulnar nerve and the anterior interosseous nerve and its motor branches as well as the relevant distances from the points of divergence were measured. The axons were counted, and the distances from the end of the main anterior interosseous nerve, its motor branches, and the motor branch of the ulnar nerve to the level of the dorsal sensory branch of the ulnar nerve were measured. Results: Our results indicate that the length, width, and number of axons of the branch of the anterior interosseous nerve to the pronator quadratus make it suitable for transfer to the motor branch of the ulnar nerve. The use of the main anterior interosseous nerve or its motor branches to the flexor pollicis longus and the flexor digitorum profundus is less feasible because of the need to graft a long segment and the longer distance from the level of transfer to the motor end points. Conclusions: The findings of the present study confirm the feasibility of motor-nerve transfer for reconstruction after an injury of the ulnar nerve. Nerve-grafting would be needed for injuries distal to the level of the dorsal sensory branch of the ulnar nerve.

The spinal cord is situated within the vertebral canal by the third month of intrauterine life. The spinal cord possesses two symmetrical enlargements, which constitute the segments of the plexuses: the cervical enlargement for the brachial plexus and the lumbosacral enlargement for the lumbar and sacral plexus. In our study, we aimed to investigate the relationship between the termination level of the lumbosacral enlargement (TLLE) and that of the conus medullaris (TLCM) during the period of fetal development and adulthood. We used a total of 75 cases: 25 fetuses (male: 16, female: 9) whose crown-rump length ranged between 90-190 mm, 25 premature and full-term neonates (male: 17, female: 8) whose post-menstrual ages ranged between 33-55 weeks, and 25 adults (male: 12, female: 13) aged between 22-72 years. The dissection technique for fetuses, ultrasonography for premature and full-term newborns, and magnetic resonance imaging (MRI) for adults were used to determine lumbosacral enlargement and TLCM. The differences between the TLCM and the termination level of the largest part of the transverse diameter of the lumbosacral enlargement were investigated. The differences between the TLLE and TLCM were found in different ratios from the period of fetal development to adulthood. Therefore, during medical treatment and surgical procedures this should be taken into account to avoid complications.

The morphologic structure of the conus medullaris and filum terminale was investigated by dissection in 123 human fetuses, obtained from Selcuk University, Faculty of Medicine and Maternity hospital of Konya between 1992–1995. In 78 fetuses, the conus medullaris and filum terminale had a normal morphologic aspect, whereas there was a slight depression or groove formation in the closure region of the caudal neuropore in 45 fetuses. In 15 fetuses, important malformations of the cranium and vertebral column were observed. The morphologic aspects of the conus medullaris in 30 fetuses were abnormal in shape and position, among them 24 fetuses had an abnormal filum terminale (grooved, depressed, thickened or duplicated) whereas it was normal in 6. Deficiency of closure of the caudal neuropore was considered to have a negative effect on the fetal development of the filum terminale.

WOS: 000306941100002, PubMed: 22794512, Background: The objective of the present study was to examine the effects of zinc supplementation on the oxidant damage in lung and liver tissues in rats exposed to a 50-Hz frequency magnetic field for 5 minutes every other day over a period of 6 months. Methods: The study included 24 adult male Sprague-Dawley rats, which were divided into the three groups in equal numbers: Group 1, the control group (G1); Group 2, the group exposed to an electromagnetic field (G2); and Group 3, the group, which was exposed to an EMF and supplemented with zinc (G3). At the end of the 6-month procedures, the animals were decapitated to collect lung and liver tissue samples, in which MDA was analyzed using the "TBARS method (nmol/g/protein)", GSH by the "biuret method (mg/g/protein)" and zinc levels by atomic emission (mu g/dl). Results: MDA levels in lung and liver tissues in G2 were higher than those in G1 and G3, and the levels in G3 were higher than those in G1 (p
