Radioprotective effect of leaves extract of Rosemarinus officinalis (ROE) has been studied against 6 Gy gamma-radiations in the liver of Swiss albino mice at various post-irradiation intervals between 12 h and 30 days. In control animals (without ROE treated irradiated), an elevation in glycogen, protein, acid and alkaline contents was found till day 5th, but thereafter decreased at successive intervals without returning to normal. Cholesterol level was found to be lower than normal till 10th day, then increased up to 20th day but later declined without restoring normal level. A similar trend of variation in these biochemical parameters was observed in experimental group (ROE pretreated irradiated) also but to a lower extent. ROE significantly delayed and inhibited the rise in these biochemical parameters. Almost normal values of such constituents were regained by day 30th in experimental animals; whereas in control animals, normal values were not ever attained. In control animals, there was an elevation in lipid peroxidation (LPx) and a decrease in glutathione (GSH) in blood and liver; whereas in experimental group, decline in LPx accompanied by an increase in GSH concentration was observed.
