Alteration in alkaline phosphatase activity of duodenal tissue following vestibulo-cerebellar modulation

Effect of electrolytic lesion in vestibulo-cerebellar area of male Wistar rats was investigated on duodenal alkaline phosphatase (AP) activity. Histomorphological observations of brain indicated, that extensive lesion restricted to the wide area of nodule including ventral uvula, resulted in significant fall of AP activity at the mucosal brush border within 20 days. A comparative behavioural study in experimental and control groups by openfield test indicated that, sympathoexcitation resulting from vestibulo-cerebellar lesion may contribute to significant alteration of AP activity in duodenum of rats.
