Antioxidant effect of royal jelly on immune status of hyperglycemic rats

Context: Diabetes mellitus and its increasing effect on endocrine functionality have been widely observed. Aims: The present study aims at investigating the histopathological changes of splenic cells in diabetic rats. Subjects and Methods: The experiment was conducted on adult male albino rats. They were categorized into four groups: Group I (negative control; fed with standard basal diet [SBD]), Group II (positive control; fed with SBD), Group III (fed on SBD + dose of 50 mg/kg of body weight royal jelly [RJ]) and Group IV were given orally RJ 100 mg/kg of b.wt. The food intake ratio and body weight gain were monitored on a weekly basis. The blood sample and organ tissue samples were collected at the end of feeding and biochemical and immunological analysis was performed for determining the blood glucose level and immune status of the investigated rats. Superoxide dismutase activity was also determined. Results: The results showed increased antioxidant enzymes and lowered glucose levels in diabetic rats fed with RJ. Conclusion: Histopathology tissues indicated moderate to extreme cellular transformations upon treated rats. The histopathological variations in treated rat cells were found to be evident. For this reason, there is likelihood that RJ may have an effect on splenic tissue repair in diabetic rats.
