    Abstract:
    OBJECTIVE: To study the effects of notoginseng, gingko leaf and rhodiola on cardiac functions and the serum inflammatory factors interleukin-6,interleukin-10, and TNF-α of rats with hypoxia deacclimatization, to explore the mechanism of hypoxia detoxification. METHODS: Forty SD rats were randomly divided into notoginseng group(n=10), gingko leaf group(n=10), rhodiola group(n=10) and high altitude control group(n=10) after fed in a hypobaric hypoxia chamber(simulated altitude of 5 000 m) for 3 month, while 10 rats fed at normal pressure and oxygen environment for 3 month were used as the plain control group. Rats in notoginseng group, gingko leaf group and rhodiola group were treated with notoginseng, gingko leaf tablets or rhodiola suspension through intragastric administration (200 mg/kg,twice a day, for 10 days). After the rats got intraperitoneal anesthesia with 10% urethane, 5 min pulmonary artery pressure curve were traced continuously while pulmonary artery pressure (PAP). Left and right ventricular systolic pressure (VSP) and ventricular diastolic pressure (VEDP), the hemodynamic parameters were detected through a multi-channel physiological recorder. Serum tumor necrosis factor-α(TNF-α), interleukin-6 (IL-6), interleukin-10 (IL-10), superoxide dismutase (SOD) and malondialdehyde (MDA) were measured. RESULTS: Right ventricular systolic pressure (RVSP), right ventricular end-diastolic pressure (RVEDP), mean pulmonary artery pressure (mPAP), left vent-ricular systolic pressure (LVSP), left ventricular end-diastolic pressure (LVEDP),IL-6,and IL-10 were higher in notoginseng group, gingko leafgroup, rhodiola group and high altitude control group than those in plain control group(P＜0.05 or P＜0.01). The contents of MDA and TNF-α were higher while the level of SOD was lower in rhodiola group and high altitude control group than those in plain control group(P＜0.01). The contents of MDA and TNF-α were lower while the level of SOD was higher in notoginseng group, gingko leaf group and rhodiola group than those in high altitude control group(P＜0.01). The levels of RV,RVHI,RVSP,RVEDP,LVSP,LVEDP,IL-10 and TNF-α were statistically changed in notoginseng group than those in gingko leaf group and rhodiola group(P＜0.05orP＜0.01). CONCLUSION: Notoginseng, gingkoleaf and rhodiola can enhance antioxidant capacity of body and improve ventricular functions and Notoginseng, gingko leaf and rhodiola can effectively enhance the functions of ventricular and hypoxia tolerance and inhibit the expressions of inflammatory factors in rats during the hypoxia deacclimatization.
