Effects of aqueous extract of Eucalyptus globulus on lipid peroxidation and selected enzymes of rat liver
The effects of repeated administration of varying concentrations of the aqueous extract of Eucalyptus globulus leaves on some biochemical parameters of rat liver were studied. Twenty four albino rats (Rattus norvegicus) with a mean weight of 148.35 g were divided into four groups (A - D) of 6 rats each. Rats in group A served as control and were administered 1 ml of distilled water while those of the...
