Research Abstract

To investigate the change and role of inducible nitric oxide synthase (iNOS) and neuronal nitric oxide synthase (nNOS) on decreasing intestinal apoptosis of refeeding after fasting in rats and to define whether the recovery of the intestinal mucosa atrophy by refeeding is associated with the levels of nitric oxide synthases (NOSs) in the jejunum. These results suggest that nNOS-involved control might be present in the regulation of iNOS activity and its-mediated apoptosis in fasting and refeeding.
