In Vitro Effects Of Melatonin On Hyaluronidase Activity And Sperm Motility In Bull Semen, Sadetti̇n Tanyildizi, Tanzer Bozkurt, Osman Çi̇ftçi̇, Fati̇h Saki̇n

Turkish Journal of Veterinary & Animal Sciences

The effects of melatonin on hyaluronidase activity of semen and spermatozoa motility of Holstein bulls were investigation in vitro. Semen samples were divided into 5 equal parts and incubated (v/v) with melatonin at the doses of 0.5, 1, 2 and 4 mM for 60 min. Percentages of spermatozoa motility, morphological abnormality and hyaluronidase activity of semen were determined at 5, 10, 15, 20, 30 and 60 min during incubation. Results show that melatonin caused a significant (P < 0.001) decrease in the spermatozoa motility, while causing a significant increase in the hyaluronidase activities of the semen. However, there was no significant difference in the percentages of abnormal spermatozoa when compared with control samples. Doses of 0.5, 1, 2 and 4 mM of melatonin in bull semen decreased the percentage of spermatozoa motility in a time- and dose-dependent manner. The mean percentages of abnormal spermatozoa were not affected by melatonin treatment. However, it caused an increased hyaluronidase activity of bull semen. In conclusion, the existence of melatonin in bull semen has a significant effect on fertilization ability by affecting spermatozoa motility and hyaluronidase activity.

Turkish Journal of Veterinary & Animal Sciences

The aim of this study was to investigate fasciolosis in a group of eosinophilic and non-eosinophilic cattle in eastern Turkey. All the cattle were examined for antibodies against F. hepatica by modified indirect excretory/secretory enzyme-linked immunosorbent assay (ES-ELISA). Of the 1200 cattle tested, 164 (13.6%) were found to be eosinophilic by absolute eosinophil counts. Out of the 164 eosinophilic cattle, 121 (73.7%) were found to be positive for fasciolosis by indirect ES-ELISA, while the rate was only 35% among the non-eosinophilic group (P < 0.001). Our data indicate that parasitic infections should be considered an important cause of eosinophilia, particularly in fasciolosis, and the indirect ES-ELISA is useful as a screening test to examine anti-F. hepatica antibodies for the diagnosis of fasciolosis in cattle.

Turkish Journal of Veterinary & Animal Sciences

We investigated the effect of ATP-MgCl_2 on myocardial hemodynamics and ultrastructure. In the in vitro study, left ventricular systolic and diastolic pressures and dp/dt values were significantly high in the ATP-MgCl_2 group beginning from 0.5 h of the reperfusion period. In the ATP-MgCl_2 group, at the end of the third hour, systolic and diastolic pressure values were 80.0 ± 6.2 and 75.2 ± 7.2 mmHg, while in the control group they were 18.4 ± 7.7 and 7.5 ± 6.8 mmHg (P < 0.05). In the ultrastructural analysis, myofibrillary damage was observed in both groups, but the mitochondrial pathologic changes were clearer in the control group. The electron microscopic score was 0.40 ± 0.061 in the ATP-MgCl_2 group and 1.2 ± 0.039 in the control group (P < 0.001). The hemodynamic and ultrastructural parameters of the specimens investigated in this study revealed that the usage of ATP-MgCl_2 may be beneficial in coping with ischemia-reperfusion damage. In the near future, with the help of more comprehensive studies, ATP-MgCl_2 is expected to be used routinely because of its potential benefits.

Glutathione reductase (GR) is important in maintaining high levels of reduced glutathione in cells. The enzyme is inhibited by some drugs used in antimicrobial chemotherapy. The effects of some antibiotics on GR activity were investigated in this study. At first, the enzyme, having a specific activity of 88.28 EU/mg proteins, was purified 1636-fold with a yield of 35%. Purity of the enzyme was checked by means of sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE). Activity of the enzyme was determined spectrophotometrically at 340 nm and in vitro effects of ofloxacin, levofloxacin, cefazolin, and cefepime were determined. The antibiotics used in …
