Improvement in nutrient handling in STZ induced diabetic rats treated with Ocimum gratissimum

Abstract

Objective:Alteration in digestive and absorptive enzymatic activities has been reported in diabetes mellitus (DM), but not with Ocimum gratissimum (OG) treatment. This study was, therefore, designed to indirectly assess the effect of DM and treatment with OG on nutrient digestion and absorption, through estimation of their fecal excretion.Materials and Methods:Animals were randomly assigned into three groups of six per group for control, DM and diabetic mellitus treated (DMT). Diabetes was induced by single intraperitoneal injection of 65 mg/kg streptozotocin in the test groups. OG was administered to the DMT group at dose of 1500 mg/kg once daily for 28 days. Fecal glucose, protein and cholesterol were determined.Results:Fecal glucose was significantly (P < 0.001) lower in the DM group compared to the control and DMT groups, with the DMT groups significantly (P < 0.001) lower than the control. Fecal protein was significantly (P < 0.001) lower in the DM group than the control whereas it was significantly lower in the DMT groups than the DM. Fecal cholesterol was significantly (P < 0.001) higher in the DM than the DMT and control groups with DMT significantly (P < 0.01) higher than the control.Conclusion:This result indicates the propensity of OG to reverse impairment of nutrient digestion and absorption in DM.
