Abstract
The present work was carried out on 50 male albino rats ranging in weight between 200–250 g. The rats were housed individually in isolated animal cages, under controlled environmental conditions, 12/12 h light/dark cycle, at room temperature (23 ± 2°C), with free access to standard rat chow and drinking water. The animals were acclimatized for 2 weeks, and then randomly divided into 5 groups; each contained 10 rats.
