متن کاملEvaluation of nitric oxide level in prepartum heifer mastitis
This study was carried out for detection of nitric oxide (NO) levels in healthy (Group 1, n:78) and infected (Group 2, n:63) quarters of pregnant heifers. The mean nitric oxide (NO) concentrations were calculated of about 15,58 ± 2,21 μM/ml and 42,69 ± 6,03 μM/ml for Group 1 and Group 2, respectively. A significant difference was found between two groups, statistically (p<0,001). The mean NO co...
