The effects of 6 weeks of VLHE administration (250 and 500 mg kg⁻¹) on the antioxidant enzyme activities in the livers of normal and streptozotocin-induced diabetic rats^a.

Parameter	Group
	Healthy control	Diabetic control	VLHE (250 mg kg−1)	VLHE (500 mg kg−1)
GPx	19.79 ± 0.60	10.44 ± 1.06*	18.18 ± 1.02**	18.24 ± 1.60**
SOD	17.09 ± 0.78	11.80 ± 0.75*	16.54 ± 0.47**	16.93 ± 0.43**

^aResults are expressed as mean ± SE (n = 5); * means in diabetic and healthy control groups are significantly different from each other (P < 0.01); ** means in diabetic + VLHE (250 and 500 mg kg⁻¹) and diabetic groups are significantly different from each other (P < 0.05).
