Dracaena Arborea Leaf Extract: A Phytotherapeutic Option for Ameliorating Oxidative Stress-Mediated Endocrine and Testicular Disorders in Alloxan-Induced Diabetic Rats

Objective: To explore and exploit these anti-diabetic properties of the leaf extracts of Dracaena arborea by investigating its therapeutic effects on blood glucose regulation, testicular and endocrine disorders in alloxan (ALX)-induced type-1 diabetic rats. Methods: Rats were divided into four groups of five animals each in a completely randomized trial and treated. ALX and then Dracaena arborea extracts (DAE) at 100 mg/kg and 300 mg/kg/ day were administered to both normal (Group A) and diabetic rats (Groups C and D) and none to the diabetic control group (Group B) for a period of 8 weeks. The serum level of glucose, follicle stimulating hormone, luteinizing hormone and free testosterone were estimated for all treated and control groups. Oxidative stress parameters such as superoxide dismutase, glutathione peroxidase, glutathione reductase, catalase, and malondialdehyde were also estimated from testicular cells of control, untreated diabetic and DAE-treated diabetic rats. Results: We observed a significant (P < 0.05) decrease in the serum glucose level as well as a drug-induced dose-dependent reduction in testosterone, follicle stimulating hormone and luteinizing hormone in the rats following type-1 diabetic conditions induction by ALX. There was a significant dose dependent response (P < 0.05) to treatment between the DAE-treated diabetic groups. Furthermore, a significant decrease (P < 0.05) in oxidative stress parameters was observed in testicular cells of diabetic rats post-treatment. Conclusions: These findings suggest that DAE is a potential beneficial phytotherapeutic agent that may be used in ameliorating hyperglycemic, endocrine and reproductive disorders in type-1 diabetic men.
