Zhen Qi Hypoglycemic Capsules (ZQHC) is a traditional Chinese herbal medicine containing medical activities by ougi (Astragalus membranaceus) and ousei (Polygonatum rhizome). Although ZQHC has been traditionally utilized as an anti-diabetic medicine in China, there is no evidence. Therefore, this study investigated the beneficial effects of ZQHC against diabetes using streptozotocin (STZ)-induced diabetic rats by biochemical and morphological methods. Eight-week old male Fisher strain rats were intraperitoneally injected with STZ (50 mg/kg of B...

Diabetes is a complex metabolic disease that exposes patients to the deleterious effects of hyperglycemia on various organs. Achievement of normoglycemia with exogenous insulin treatment requires the use of high doses of hormone, which increases the risk of life-threatening hypoglycemic episodes. We developed a gene therapy approach to control diabetic hyperglycemia based on co-expression of the insulin and glucokinase genes in skeletal muscle. Previous studies proved the feasibility of gene delivery to large diabetic animals with adeno-associated viral (AAV) vectors...
