عنوان انگلیسی The effect of citric acid and citrate on protoplasmic droplet of bovine epididymal sperms
چکیده انگلیسی مقاله For evaluation of citric acid and citrate effects on bovine epididymal protoplasmic droplets, fifty bovine testes were collected in the October 2007 till June 2008 from Urmia slaughterhouse and transported to the laboratory in a cool container filled with 5 °C ice pack. Caudal epididymis was incised and sperm cells were put into Petri dishes containing hams f10 media with 10% fetal calf serum (FCS), which were kept in 37 °C, CO2 incubator. Then sperm cells were counted and 50-milion per mL concentration was prepared. After this stage, three dilutions of citric acid (0.1, 0.2, 0.3 N) and one dilution of citrate (1N), based on normal osmolarity and normal pH were added to a micro tube containing 25 milion per mL sperm. Then one-step eosin-nigrosin staining in 30-60-120-240-360 minutes was performed and slides were evaluated with 1000-x phase contrast microscope and 200 sperm cells per slide were counted. The results revealed significant difference between blank and citric acid 0.3 N. The proportion of protoplasmic droplet in group consisting of 0.3 N acid citric in 120-240-360 minutes, was significantly lower than that of blank (P < 0.05). There was no significant difference between citrate – blank and citric acid 0.1N-blank groups, but after 240 minutes significant difference was observed between blank & citric acid 0.2 N (P < 0.05). In conclusions citric acid based on dilution and time duration can reduce the proportion of bovine epididymal sperm cytoplasmic droplets.
