6、ucts. Genistin shows a dose-dependent superoxidescavenging effect and exhibits major effect at 200 M, corresponding in activity to 0.08 U/mg protein superoxidedismutase (SOD). Results demonstrate that Genistin exhibits a significantly (P0.01) and a dose-dependent inhibitoryeffect on the human cancer

7、 cell examined, and at higher concentration (100 M), the cell viability is 59%. Genistin alsoinduces a significant and dose-dependent increase in ROS formation when compare with the untreated control1.体内研究 Myocardial infarct is markedly diminished by pretreatment with Genistin, particularly at the h

After 1 h ofreperfusion, preconditioning with Genistin at dosages of 20 to 60 mg/kg significantly attenuats the release of lactate dehydrogenase (LDH), creatine kinase (CK) in a dose-dependent manner compare with the I/R group. Results showthat the level of malondialdehyde (MDA) is decreas

Pretreatment with Genistin (20, 40 and 60 mg/kg) also prevents the expression of P2X7, p-IB, andp-NF-B p65 compa
