the animals in the first group (control) were fed with a standard rodent diet containing 6.4 mgB/kg, and
the animals in the experimental group were fed with a standard rodent diet added with a supra-
nutritional amount of boric acid and borax (100mgB/kg) throughout the experimental period of 28
days. The B compounds decreased malondialdehyde (MDA), DNA damage, the protein carbonyl content
(PCO) level in blood,and glutathione (GSH) concentration in the liver, Cu–Zn superoxide dismutase
(SOD), andcatalase (CAT) activity in the kidney.The B compounds increased GSH concentration in
blood and the vitamin C level in plasma.Consequently,our results demonstrate that B supplementation
(100 mg/kg) in diet decreases LPO, and enhances the antioxidant defense mechanism and vitamin
status.There are no differences in oxidant/antioxidant balance and biochemical parameters except for
serum vitamin A and liver GSH concentration,between the boron compounds used in this study
