BACKGROUND: The effects of Vit C on liver and renal function and the tissues oxidative damage was investigated in hypothyroid rats.
MATERIALS AND METHODS: The pregnant rats were divided into 5 groups (n=6): (1) Control; (2) Propylthiouracil (PTU; 0.005%), (3-5) PTU plus 10, 100 or 500 mg/kg b.w. Vit C. The drugs were added to the drinking water of the dams and their pups during lactation period and then continued for the offspring through theﬁrst 8 weeks of their life. Finally, 7 male offspring from each group were randomly selected.
RESULTS: Thyroxine, protein and albumin concentrations in the serum and thiol content and superoxide dismutase (SOD) and catalase (CAT) activities in renal and liver tissues of hypothyroid group was lower (all P<0.001) while, aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALK-P), creatinine and blood urea nitrogen (BUN) concentrations in the serum and malondialdehyde (MDA) in the liver and renal tissues were higher than the control (all P<0.001). All doses of Vit C increased thyroxine, protein and albumin and thiol content in in renal and liver tissues while, decreased AST, ALT and ALK-P concentration and MDA in liver and renal tissues compared to PTU group (P<0.05-P<0.001). Creatinine, BUN and SOD and CAT were improved by both 100 and 500 mg/kg of Vit C in the renal (P<0.05-P<0.001) and by 100 mg/kg in the liver (P<0.05-P<0.001).
CONCLUSION: Vit C improved liver and renal function of hypothyroid rats which might be due to its protective effects against tissues oxidative damage.
