Figure 1. The average animal body weight gain in each group. G-6-PD enzyme activity was significantly reduced in the animals that were treated with dexamethasone. It was observed that rats treated with 12 mg/kg/ body weight of dexamethasone demonstrated higher significant reduced G-6-PD enzyme activities relative to the control and rats treated with 10 mg/kg and 7 mg/ kg/body weight of dexamethasone as shown in Figure 2.
