Objective: To investigate anti-oxidative protective effects and potential anti-apoptosis mechanisms of He Ying An Xin-Formula (HYAX-F).
Method: VSMC were incubated by H2O2 (200 μmol/L) for 2 h as oxidative stress control group, same dosage of H2O2 was administered 2 h after treatment with HYAX-F (100 g/mL, 50 g/mL, 25 g/mL) as therapeutic group and incubated for another 24 h, cell supernant content of GSH and MDA were measured. Sub-cutaneous injection in back with D-galactose (125 mg/kg) to establish ageing rat model. Control group: D-galactose 125 mg/kg, therapeutic groups: HYAX-F 500 mg/kg+D-galactose 125 mg/kg, HYAX-F 250 mg/kg+D-galactose 125 mg/kg, HYAX-F 125 mg/kg+D-galactose 125 mg/kg, normal group and young group. The RT-PCR technique was used to measure the expression of relevant genes, such as tumor necrosis factor- alpha (TNF-α) and B-cell lymphoma-2(Bcl-2) in the tissues of brain and liver.
Results: Compared with the control group, HYAX-F can significantly enhance the content of GSH (P<0.05) and decrease the content of MDA (P<0.01). Also HYAX-F can significantly decrease TNF-α expression and increase Bcl- 2 expression in rats brain and liver tissues (P<0.05, P<0.01).
Conclusion: HYAX-F has greatly protective effects on anti-oxidative of rat VSMC and anti-apoptosis of ageing rats.
