Comparative Efficacy of Combined Formulation of Andrographis Paniculata, Lagerstroemia Speciosa and Tribulus Terrestris with Glimepiride on Renal and Pancreatic Injury in Alloxan Induced Type-1 Diabetic Mice

Many medicinal plants are becoming increasingly popular for the treatment of various ailments, including diabetes, all around the world. This study was designed to elucidate the comparative efficacy of Tribulus terrestris, Andrographis paniculata, and Lagerstroemia speciosa on glucose intolerance, lipid profile, renal and pancreatic injury in alloxan induced type-1 diabetic mice. In this study, four-week-old male Swiss Albino mice were divided into six groups of five each. To assess toxicity, Group-X was given saline water, while Group-Y was given a combination herbal formulation at a high dose (1 g/kg bwt). No adverse effect of combined formula on body weight and blood glucose was observed in normal healthy mice. The other four groups were labeled as Group-A, healthy normal mice; Group-B, Diabetic mice; Group-C, Diabetic mice treated with Andrographis paniculata, Tribulus terristris @ 200 mg/kg and Lagerstroemia speciosa @ 0.5ml/animal; and Group-D, Diabetic mice treated with Amaryl®@ 800 g/kg bwt. The combined formulation improved body weight loss significantly (P<0.001) compared to diabetic control group after 8 weeks of treatment. Combined formulation and Amaryl® decreased non-significantly total cholesterol, plasma triglyceride and plasma creatinine level compared to diabetic control. However, HDL and LDL levels remained unchanged by the treatment. Consistent with these findings, histopathological evaluation revealed that combined formulation partially improved renal glomerular sclerosis and hypertrophy, tubular damage and pancreatic β-cells damage reflected its renal and pancreatic damage curative property. The obtained results suggest that combined use of Andrographis paniculata, Tribulus terrestris and Lagerstroemia speciosa as antidiabetic herbal formulation, synergizing its therapeutic value in treating hyperglycemia and diabetes related complications mainly renal and pancreatic injury.
