Does aqueous leaf extract of Ocimum gratissimum potentiate activities of plasma and hepatic antioxidant enzymes in rats?
Data of the study suggest that the oral administration of the aqueous extract of O. gratissimum may impair naturally generated oxidant/toxicant activity and thereby enhance specific activities of hepatic antioxidant enzymes in rats.
More detailed exposure assessment of indoor air pollution due to the use of smoky coal and subsequent linkage on an individual level to ongoing epidemiological studies should provide more insight in the etiology of lung cancer in this region.
