The Effect Of Trifolium Pratense On Spermatogenesis And Its Acute Toxicity (Ld_{50}) In Mice, Tülay Bakirel, Oya Keleş, H. Hakan Bozkurt, Kemal Ak
Turkish Journal of Veterinary & Animal Sciences
Trifolium pratense contains phytoestrogens and thus it has estrogenic activity. Estrogen has an important role in the development of the reproductive system and the maintanence of its function, and for this reason the effect of Trifolium pratense on sperm parameters and spermatogenesis was examined. Furthermore, its acute toxicity was established. In this study, the motility and morphology of epididymal spermatozoa taken from animals fed diets contains 20% and 40% Trifolium pratense, were affected. Statistically insignificant differences in the diameter of the seminiferous tubule and the number of primary spermatocytes between the control and experimental groups were observed. Intraperitoneal LD_{50} was …

The Effects Of Lead On The Small Intestinal Motility Of Guinea Pigs, Mehmet İri̇adam, Vedat Sağmanligi̇l
Turkish Journal of Veterinary & Animal Sciences
In this study, 18 adult guinea pigs, weighing 300-450 g, were divided into three equal groups, and their small intestinal segments (proximal and distal ileum) were removed and kept in vitro in an isolated organ bath in order to record the responses mainly produced by lead and acetylcholine. For the tissues of the first group, the noncumulative concentration-response curves of lead obtained were compared by applications at concentrations ranging from 3x10^{-8} M to 3x10^{-5} M alone, in the presence of verapamil (3x10^{-5} M) and in Ca^{++} free solution. In the second group, the responses to lead at the same concentrations …

Turkish Journal of Veterinary & Animal Sciences
The effects of different nitrite doses (100, 150 and 200 ppm NaNO_2) and starter culture (Lactobacillus plantarum + Staphylococcus carnosus) on Escherichia coli 0157:H7 were investigated in this study. Sucuk batter was inoculated with Escherichia coli 0157:H7 (10^6 /g). The count of Escherichia coli 0157:H7 in sucuk samples was determined periodically during ripening/storage by a quantitative method. Lactic acid bacteria (LAB), Enterobacteriaceae counts, pH, nitrite and salt content were also recorded. The number of E. coli 0157:H7, which was 10^6 kob/g in sucuk batter, decreased during the ripening/storage period at a rate of 0.5 log cycles on the 3^{rd }day, …

Leishmania Infantum In A Dog: Case Report, Remzi̇ Gönül, Seçki̇n Serdar Arun, Tamer Dodurka, Erol Handemi̇r
Turkish Journal of Veterinary & Animal Sciences
Leishmaniasis is a worldwide, parasitic disease found in the Mediteranean area, Africa, Asia and Central and South America that affects mainly dogs, humans, and rodents. Dogs are the domestic reservoirs of the visceral form so that early detection of canine infections including complex clinical features may be important in the control of lehismaniasis. In this article we compared the clinical and laboratory results of leishmaniasis, which was diagnosed immunologically and histologically in a dog.

Turkish Journal of Veterinary & Animal Sciences
This study was carried out on isobrown chicks fed from one day old on a diet containing 1% hot red pepper. Lenfoid infiltration and hyperemic areas in the parenchym, and hypertrophy in most of the glomeruli were observed. A thickening and adhesion of parietal and visceral sheets was observed in the glomeruli of some of the experimental groups. The average glomerulus diameter of the experimental groups was much more than that of the control groups, and these differences were thought to be statistically significant.

Effects Of Progesterone And Testosterone On The Hyaluronidase Activities And Sperm Characteristics In Sheep, Sadetti̇n Tanyildizi, Tanzer Bozkurt
Effects Of Progesterone And Testosterone On The Hyaluronidase Activities And Sperm Characteristics In Sheep, Sadetti̇n Tanyildizi, Tanzer Bozkurt
Turkish Journal of Veterinary & Animal Sciences
The aim of this study was to determine the effects of progesterone and testosterone hormones on the hyaluronidase activities of serum and semen and on sperm characteristics in sheep. Thirty healthy Akkaraman sheep were used. The progesterone and testosterone were injected intramuscularly at the rate of 0.5 mg/kg and 5 mg/kg, respectively. Then the blood and semen samples were obtained from the sheep at 1, 2, 4, 24, 48, 72 and 168 h. The serum hyaluronidase activities of ewes and rams in progesterone and testosterone groups increased significantly (p < 0.01, p < 0.001) when compared with the control groups at all times. Additionally, there were significant (p < 0.001) increases in the levels of semen hyaluronidase activity in the progesterone group except at 4 h. Furthermore, semen hyaluronidase activities in the testosterone group were detected to decrease significantly (p < 0.01) in comparison with the control rams except at 4 h. The use of progesterone and testosterone caused a significant (p < 0.05, p < 0.01) increase in spermatozoa motility, respectively. However, sperm concentrations were determined to decrease significantly (p < 0.01, p < 0.001) in both groups. Although the values for semen volume decreased significantly (p < 0.05, p < 0.01) in the progesterone group, the same values were observed to increase significantly (p < 0.01) in the testosterone group except at 48 h when compared with the control groups. The results of this study showed that there were no significant correlations between semen hyaluronidase activities and sperm characteristics. In conclusion, the use of both hormones did not have any deleterious effects on hyaluronidase activities but for the semen samples in the testosterone groups. However, progesterone and testosterone hormones cause harmful effects on the fertilization ability of rams due to decreased sperm concentration values.
Thymic Nurse Cells Determined In Situ At The Light And Electron Microscopic Level, F. Fi̇gen Kaymaz, Atti̇la Dağdevi̇ren
Thymic Nurse Cells Determined In Situ At The Light And Electron Microscopic Level, F. Fi̇gen Kaymaz, Atti̇la Dağdevi̇ren
Turkish Journal of Veterinary & Animal Sciences
Thymic nurse cells are isolated thymic epithelial/thymocyte complexes described in vitro. Their in vivo existence is controversial. We examined rat thymi in order to distinguish thymic nurse cells in vivo using the zinc iodide-osmium tetroxide (ZIO) fixation/staining technique. There were mainly two types of strongly ZIO reactive cells in the thymic cortex: macrophages and small clusters of thymic epithelial cells. The latter group was composed of thymic epithelial cells and intact thymocytes forming complexes. Thus we suggest that these structures are in situ equivalents of thymic nurse cells.

Turkish Journal of Veterinary & Animal Sciences
Two and five specimens of the blackfin sorcerer, Nettastoma melanurum, were trawled on 25 and 30 April 2001 respectively at Samandağ, Hatay (36º10'N, 35º20'E; 36º05'N, 35º40'E) at about 80-200 m depth. It is recorded for the first time from the eastern Mediterranean coast of Turkey. Thus, a new species and family have been added to the fish fauna in Turkish seas.
