Sığırların normal doğum ve güç doğumunda eritrosit arginaz aktivitesi ve plazma nitrik oksit düzeylerinin karşılaştırılması

This study was aimed to investigate erythrocyte arginase activity and plasma nitric oxide (NO)levels in dystocia and normal calving of cows and compare these parameters. The study materialconsisted of 16 cows, 3 8 years old, brought for parturition at term to the Clinic of Obstetrics andGynecology at F ı rat University. Blood samples of cows normally calving and dystocia were takeninto blood collecting tubes with heparin from the jugular vein in the first half hour after delivery andcentrifuged at 3000 rpm for 10 minutes. Plasma NO levels and erythrocyte arginase activities weremeasured. The erythrocyte arginase activity in cows normally calving was significantly increasedcompared to that in cows with dystocia (P
