Values are expressed as Mean ± S.D. Values are taken as a mean of five individuals experiments.

Values not sharing a common superscript letter differ significantly (DMRT).

Units:

Superoxide dismutase- Units/mg of protein.

Catalase- (μ moles of H₂O₂ utilized /min/mg/protein.

Glutathione-S-transferase- μmoles of CDNB-Conjugate formed/mg of protein.

Glutathione peroxidase- μg of GSH/mg of protein.

^a Control group.
