Effect of vitamin "A" on free radical cascade in pregnancy induced hypertension

The role of vitamin A therapy in pregnancy induced hypertension (P.I.H.) on free radical cascade was studied in P.I.H. patients of third trimester. It was found that vitamin A therapy causes statistically significant decrease in lipid peroxidation. However it has no effect on superoxide dismutase and catalase. This indicates that vitamin A acts as chain breaking antioxidant. The present study opens a future prospective of giving vitamin A for the prophylaxis of P.I.H.
