ABSTRACT
Exercise fatigue is a physiological phenomenon not only for athletes, but also for astronauts. It is vital for athletes with hard training and astronauts with the heavy exercises for the mission in manned space flight to know how to solve the exercise fatigue. This article reviewed current commonly used TCM protective measures against fatigue.
ABSTRACT
Objective To investigate effects of Taikong Yangxin Prescription on left ventricular pump and contract function in rat after tail suspension.Methods Twenty four male Sprague-Dawley(SD)rats were randomly and divided into three groups:(A)normal control group,(B)tail-suspension group and(C)Chinese herb compound group(taking Taikong Yangxin Prescription and tail suspension).The left ventricular functions in rats were examined by echocardiography separately after 7 d and 28 d tail-suspension.Results After 28 d of tail-suspension,as compared with the tail-suspension group,LVDD in Chinese herb compound group increased significantly(P
ABSTRACT
Object To study the effects of active fraction L.F04 from the ground part of Lycopus lucidus Turcz. var. hirtus Reg. on platelet aggregation and thrombosis formation and investigate its mechanisms of promoting blood circulation and removing blood stasis. Methods The effects of L.F04 on platelet aggregation induced by ADP in vivo, thrombosis of artery vein side road and thrombus formed in rotary loop in vitro were examined, the rat model of blood stasis made by injecting high molecular weight dextran (HMWD) was used. Results L.F04 0.408 and 0.204 g/kg evidently inhibited the ADP induced increase of platelet maximum aggregation rate in vivo in HMWD model, with a concentration dependent manner. Compared with the control group, the thrombus weight in rat model of blood stasis was increased significantly and the length of thrombus was shown an increasing trendency. L.F04 0.408 and 0.204 g/kg both shown the anti thrombosis effect. L.F04 0.408 g/kg showed better effects of lessening the thrombus dry weight and wet weight. Both L.F04 0.408 and 0.204 g/kg could inhibit the thrombosis of artery vein side road, the inhibition rates are separately 27.41% and 27.14%. Conclusion L. lucidus var. hirtus F04 could significantly inhibit platelet aggregation and thrombosis formation.
