In this paper, the pharmacokinetic parametersof Zinc L-lysinate and Zinc Gluconate in rabbits arestudied by using the atomic absorption spectropho-tometry method. The results show that the serumconcentration-time curves of Zinc L-lysinate andZinc Gluconate in rabbit fit to one-compatmentmodel and a two-compartment model, respective-ly, The main pharmacokinetic parameters of ZincL-lysinate are: t_(1/2) (ke) 1. 01 h, T (p) 1. 08 h, andCI/F (s) 39. 63 1/kg. h; of Zinc Gluconate are: t_(1/2)(?) 9. 49h, T (p) 1. 3h, and Cl (s) 13. 14 1/kg. h.

AIM:To explore the mechanism of PX-12 induced apoptosis of hepatocellular carcinoma cells.METHODS:Human hepatoma cell line Huh7 was se-lected as the main research object.After the cells were treated with thioredoxin inhibitor PX-12,the cell viability was detected by CCK8 method,the cell mi-gration ability was detected by cell scratch test,the cell proliferation ability was detected by cell prolif-eration kit,the levels of intracellular reactive oxygen species and apoptosis were detected by flow cy-tometry,and the expression of apoptosis-related proteins were detected by Western blot.RESULTS:Compared with the control group,the cell viability,migration ability and proliferation ability of PX-12 treatment group were significantly decreased(P＜0.05),and the level of intracellular reactive oxygen species was increased(P＜0.05)in a concentration-dependent manner.Apoptosis inhibitor Z-VAD-FMK and antioxidant NAC could restore the cell viability,and NAC could reduce the accumulation of intracel-lular reactive oxygen species induced by PX-12 and restore the apoptosis induced by PX-12(P＜0.05).CONCLUSION:PX-12 induces apoptosis of hepato-cellular carcinoma cells through oxidative stress.
