猴头菇对小鼠抗疲劳作用的实验研究

分别以猴头菇干粉（猴头菇Ⅰ组）和猴头菇浸出液（猴头菇Ⅱ组）饲喂小鼠，观察猴头菇对小鼠血清乳酸脱氢酶（ＬＤＨ）活力、血乳酸、血清尿素氮（ＢＵＮ）、肝糖原、肌糖原含量及运动耐力的影响。结果表明：实验６０ｄ后，猴头菇Ⅰ、Ⅱ组ＬＤＨ活力、肝糖原及肌糖原含量明显高于对照组（Ｐ＜０．０５或Ｐ＜０．０１）；运动后血乳酸的水平和ＢＵＮ的增量明显低于对照组（Ｐ＜０．０５或Ｐ＜０．０１）；运动后血乳酸消除速率显著高于对照组（Ｐ＜０．０５）；在运动耐力测定时在水中淹死的时间比对照组长得多（Ｐ＜０．０５）。提示：猴头菇具有明显的增强运动能力和解除疲劳的作用。

EFFECT OF HEOCEHOG HYDNUM ON THE DELAY OF FATIGUE IN MICE

Two groups of mice were fed with either hedgehog hydnum powder or extract forsixty days. For the assay of fatigue, the activity of serum lactute dehydeogenase, theserum urea nitrogen content, blood lactic acid, hepatic and muscular glycogen, and thephysical stamina of the mice were determined. The activity of serum lactute dehydrogenase and the hepatic and muscular glycogen content in the experimental mice were evidently higher than that in the control mice (P<0. 05 or P<0.01 ). After exercise, theincrease in blood lactic acid and serum urea nitrogen in the experimental mice was significantly lower than that in the control mice (P<0. 05 or P<0.01 ), but the rate of elimination of blood lactic acid in the experimental mice was significantly higher thanthat in the control mice (P<0. 05). In the physical stamina swimming, the experimental mice drowned after a longer Period of time than the control mice (P<0. 05). In conclusion hedgehog hydnum had a significant effect on raising physical stamina and delaying fatgue in mice.
