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.
