摘要: Disclosed are a deer-derived specific peptide and a detection method therefor; by screening through a large number of experiments, a ratio of relative contents of two deer-derived peptides is determined, and a graph is drawn by using a proportion of a deer antler gelatin in a mixed gelatin as an abscissa and using a value of Apeptide 1/Apeptide 2 as an ordinate; the proportion of the deer antler gelatin is linear with Apeptide 1/Apeptide 2 as a standard curve equation to distinguish a deer hide gelatin from the deer antler gelatin; the method can be used for distinguishing the deer antler gelatin from the deer hide gelatin, and controlling the quality; a defect in the prior art that the deer antler gelatin and the deer hide gelatin are difficult to distinguish in appearance, and are also difficult to distinguish by using a specific peptide fragment, is solved.

摘要: Disclosed is an application of verbascoside in the preparation of drugs for preventing and treating type II diabetic nephropathy. The protective effect of verbascoside on type II diabetic nephropathy and the action mechanism thereof are also included in the invention. The results show that verbascoside may improve liver injuries caused by high glucose, and reduce levels of serum creatinine, urea nitrogen, microalbuminuria and blood lipid (total cholesterol and triglyceride), fasting blood sugar and serum insulin in spontaneous diabetic db/db mice, and significantly reduce expressions of TGF-β1 and its signal transduction protein Smad3 and Smad4 and α-SMA in kidney tissues. Meanwhile, verbascoside may improve liver injuries caused by high glucose, and inhibit HK-2 proliferation and EMT formation. In conclusion, verbascoside induces significant protection on type II diabetic nephropathy, and its action mechanism is to protect kidney by regulating oxidative stress response, inhibiting TGF-β/smad signal pathways and improving renal fibrosis.
