摘要
以雄性小鼠为实验对象,采用递增强度游泳训练模型,对小鼠灌服玄参多糖溶液,四周后测定力竭运动时间,及血糖、肌糖原、肝糖原、血乳酸等生化指标。结果表明,服用玄参多糖能提高肌糖原和肝糖原含量,减少力竭运动后血乳酸的堆积,维持血糖恒定,延长小鼠力竭时间,说明玄参多糖能够缓解机体运动性疲劳的产生。
Figwort root, the dried root of Scrophularia ningpoensis Hemsl, is a traditional Chinese medicinal material, which has been widely used for clinical purposes due to its functions of cooling blood, nourishing Yin, purging pathogenic fire and detoxicating. This study aimed at making clear whether the polysaccharide from figwort root has antifatigue effect. A total of 90 Ktmming male mice were randomly divided into five groups: sedentary control group of 10 mice, swimming control group of 20 mice orally administered with normal saline, and three swimming model groups of 20 mice each orally administered with high, medium and low doses of the polysaccharide from figwort root, respectively. After 30 rain weight-loaded swimming training every day for three weeks, the exhaustive swimming time of mice was measure and the blood sugar, muscle glycogen, liver glycogen and blood lactic acid were assayed. Obvious increases in the contents of muscle glycogen and liver glycogen were observed in medium and low-dose polysaccharide-administered swimming model mice in comparison with swimming control group, accompanied with sharp reduction of accumulation of the blood lactic acid and marked prolongation of the exhaustive swimming time, but the blood sugar remained constant. This study showed that the polysaccharide from figwort root has a certain antifatigue effect.
