ABSTRACT
@#Objective To study the anti-fatigue effect of Cynomorium songaricum flavone(CSF)on old rats.Methods50 old male Wistar rats were randomly divided into the control group(no swimming,no drugs),single swimming group(swimming,given saline by gavage),and three swimming plus CSF groups(swimming,given CSF 20 g/kg weight,10 g/kg weight and 5 g/kg weight respectively),total five groups with 10 animals in each group.Animals swam with free swimming in endless cycles water 30 minutes once every day for 10 days.The level of monoamine oxidase(MAO) and glutathione peroxidase(GSH-px) in blood of animals were examined by MAO kit,GSH-px kit and ultraviolet spectrophotometer at 11th day.ResultsCompared with single swimming group,the body weights of swimming plus CSF groups increased significantly by 12.9%,80.6% and 200% respectively(P<0.01);swimming times before sinking increased by 19.4%,29% and 48.4%;sinking times of each rat(time/10 min) decreased by 17.8%,43.2% and 72.9%;total swimming times increased by 2.8%,7% and 29.6% respectively(P<0.01);MAO decreased by 60%,69.8% and 80.5%,GSH-px increased by 465.3%,563.8% and 635% respectively(P<0.01).ConclusionCSF shows anti-oxidative and anti-fatigue properties and can be given as prophylactic/therapeutic supplements for increasing antioxidant enzyme activities and preventing lipid peroxidation during strenuous exercise.

ABSTRACT
Aim To study the inhibitory effect of Maoeryan vegetable acid on human SGC-7901 strain cells and the mechamism of it. Methods The inhibitory effects of Maoeryan vegetable acid on human SGC-7901 strain cells were determined by flow cytometry, methods of MTT and trypan-blue.Results Maoeryan vegetable acid at a does of 10.0, 1.0 and 0.1 mg?L -1 was given to human SGC-7901 strain cells for 48 h,respectively, and the inhibitory rate of human SGC-7901 strain cells was 82.9%,42.7% and 24.6%,respectively;cellular growth inhibitory rate was 76.4%,56.9% and 42.6%, respectively;as well as apoptosis rate was 26.8%,22.5% and 15.6%, respectively. Conclusion The Maoeryan vegetable acid has significant inhibitory effect on human SGC-7901 strain cells and the inhibitory effect increases with the increase of concentration and time.
