Özet:

 

Arginase (L-arginine amidino hydrolase E.C. 3.5.3.1) is an enzyme catalyzing the last stage of the Krebs-Henseleit cycle  and, thus, converting arginine into urea and ornithine. Arginase also plays a part in protein and polyamine synthesis and is affected  by hormones in terms of metabolic status.  In the present study, erythrocyte, saliva, and serum arginase activity together with serum urea and estrogen levels were examined  in Akkaraman and Ivesi sheep in pregnancy and postpartum. Comparisons were then made between the species. In pregnancy the  urea level in saliva increased. However, the urea level in serum decreased. No clear difference was observed in the level of urea in  the erythrocytes of pregnant sheep. In pregnancy, it was observed that the estrogen hormone level increased, but erythrocyte  arginase activity did not change. The saliva arginase level increased in both species. When the species were compared, it was found  that, both in pregnancy and postpartum, erythrocyte and saliva arginase activity in Akkaraman and Ivesi sheep had significantly  increased, but the urea level in the saliva and estrogen level decreased. However, no change was found in the urea level of serum  and erythrocyte in either species. In pregnancy, the increase in saliva arginase activity was probably caused by hormone actions.  However, the erythrocyte arginase activity did not increase. This observation supports the hypothesis that arginase is synthesized by  two different genes.
