Modulations in Anti-Oxidant Activities of Selected Gastro-Intestinal Tissues in Alloxan-Induced, Silymarin Treated Diabetic Wistar Rats
Open Journal of Gastroenterology
Diabetes mellitus (DM) is reportedly the commonest metabolic disorder with multi organ involvement. By inducing DM (with Alloxan) in Wistar rats, current study investigated the changes in antioxidant activities of selected gastrointestinal (GI) tissues [stomach, duodenum, pancreas and liver], upon treatment with Silymarin and/or Vitamin C. One hundred and twenty five (125) adult male wistar rats of between 130 to 180 grams were procured for the study. Five units of one control and four
... l and four experimental units were designated with twenty five (25) rats per group (n = 25); Unit 1: Control rats, Unit 2 were DM induced, Silymarin untreated rats, and Units 3, 4 and 5 were DM induced, vitamin C, Silymarin and Vitamin C + Silymarin treated respectively. Following four (4) weeks of administration of test substance(s), rats were euthanized and blood samples obtained for biochemical and antioxidant assay on aforementioned GI tissues. One way analysis of variance (ANOVA) and Students t-test at p < 0.05 were set to be statistically significant on analysis of obtained data. First, study found DM to have caused a statistically significant decrease in body weight prior to sacrifice. Catalase (CAT), superoxide dismutase (SOD) and malonaldehyde (MDA) levels were also seen to significant increase (p < 0.05) at comparison of extract treated unit to control. Study also observed a significant change in pancreatic, liver, and duodenal anti-oxidant marker levels with Vitamin C, Silymarin and Vitamin C + Silymarin co-administrations to diabetic rats. It can therefore be said, that DM caused a destructive alteration pancreatic histo-architecture with improved functional capabilities in wistar rats at administration of Silymarin and vitamin C. Thus, Silymarin posed antioxidant potentials, with ameliorated pancreatic dysfunctions.
