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

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

Groups Catalase (UnitsA/mg protein) Superoxide dismutase (UnitsB/mg protein)
Normal 3.12 ± 0.29a 7.75 ± 0.38a
Normal + SPEt (200 mg/kg) 4.00 ± 0.20b 7.05 ± 0.28a
Diabetic control 0.86 ± 0.05c 5.17 ± 0.30b
Diabetic + SPEt (200 mg/kg) 2.75 ± 0.20d 7.32 ± 0.46c
Diabetic + Glibenclamide (600 μg/kg) 1.98 ± 0.11e 6.32 ± 0.30d
  1. Values are given as mean ± SD for 6 rats in each group.
  2. Values not sharing a common superscript letter differ significantly at p < 0.05 (DMRT).
  3. Duncan procedure, Range for the level 2.95, 3.09, 3.20, 3.22.
  4. A – μmole of H2O2 consumed/minute.
  5. B – One unit of activity was taken as the enzyme reaction, which gave 50% inhibition of NBT reduction in one minute.
