摘要
目的探讨冬虫夏草对肌梭传入放电的影响。方法用蟾蜍缝匠肌制备单一肌梭标本以空气隔绝法记录单一肌梭的传入放电,观察冬虫夏草水提液对肌梭传入放电的影响。结果应用50mg/L、100mg/L、200mg/L冬虫夏草水提液后,肌梭的传入放电分别由(0.85±0.12)Hz、(0.87±0.12)Hz、(0.84±0.10)Hz增加至(10.52±2.48)Hz、(20.79±3.03)Hz、(29.25±4.08)Hz。结论冬虫夏草水提液可以使肌梭的传入放电频率明显增加,且呈剂量依赖关系。
This paper discusses the effect of cordycepin on afferent discharge of muscle spindle. The afferent discharge of isolated toad muscle spindle is recorded using air resistance technique. The effect of eordycepin on discharge rate of muscle spindle is observed. The result shows that after administration of 50mg/L, 100mg/L and 200mg/L cordycepin,the spontaneous discharge of muscle spindle increases from （0. 85±0, 12）Hz, （0.87±0. 12）Hz and （0. 84±0. 10）Hz to （10. 52±2. 48）Hz,（20.79±3. 03）Hz and （29.25±4. 08）Hz respectively, It concludes that Cordycepin can significantly increase the afferent discharge rate of muscle spindle ,and with the relation of dosage dependent.
