Values are given as means ± S.D from six rats in each group.

   Values not sharing a common superscript vertically differ significantly at P<0.05 (DMRT).

x- One unit of SOD is defined as the enzyme concentration which gives 50% inhibition of NBT reduction in one minute.

y- One unit of CAT is defined as the mmole of hydrogen peroxide consumed per minute.

z- One unit of GPx is defined as the mg of glutathione consumed per minute.
