Protective role of Scoparia dulcis plant extract on brain antioxidant status and lipidperoxidation in STZ diabetic male Wistar rats

Table 3 Changes in activities of catalase and superoxide dismutase in brain of normal and experimental rats

Groups	Catalase (Units^A/mg protein)	Superoxide dismutase (Units^B/mg protein)
Normal	3.12 ± 0.29^a	7.75 ± 0.38^a
Normal + SPEt (200 mg/kg)	4.00 ± 0.20^b	7.05 ± 0.28^a
Diabetic control	0.86 ± 0.05^c	5.17 ± 0.30^b
Diabetic + SPEt (200 mg/kg)	2.75 ± 0.20^d	7.32 ± 0.46^c
Diabetic + Glibenclamide (600 μg/kg)	1.98 ± 0.11^e	6.32 ± 0.30^d

Values are given as mean ± SD for 6 rats in each group.
Values not sharing a common superscript letter differ significantly at p < 0.05 (DMRT).
Duncan procedure, Range for the level 2.95, 3.09, 3.20, 3.22.
A – μmole of H₂O₂ consumed/minute.
B – One unit of activity was taken as the enzyme reaction, which gave 50% inhibition of NBT reduction in one minute.
