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 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.
