  • USES OF VERBASCOSIDE IN TREATMENT OF DIABETIC-ASSOCIATED KDINEY INJURY AND DIABETIC-ASSOCIATED LIVER INJURY
    Publication number: 20210161929
    Abstract: 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-?1 and its signal transduction protein Smad3 and Smad4 and ?-SMA in kidney tissues. Meanwhile, verbascoside may improve liver injuries caused by high glucose, and inhibit HK-2 proliferation and EMT formation.
