In our study, we investigated the role of heme-oxigenase synthase (HO), which produce endogenous vascular protective carbon monoxide, in the development of sexual dimorphism in rats. We found that HO synthase enzyme activity, and the expression its HO-1 and HO-2 isoenzyme were increased in female rat aorta and left heart ventricle compared to males. Moreover...
