Experimental Animals: A total number of 40 adult male
albino rats weighing 150 -170 g were used in this study.
They were kept in the animal house for one week for
proper acclimatization before starting the experiment
under the same controlled laboratory conditions of
illumination (12 h light/12 h darkness), temperature
20-25 °C and ventilation. They were housed in stainless
steel cages, maintained on standard rodent diet [21] and
water ad libitum throughout the experimental period.
