Effect of Glucose Deprivation on Post-Tetanic Enhancement of Evoked Aferdischarge on Postganglionic Sympathetic Nerve of the Rat Superior Cervical Ganglion in Vitro

缺糖對大白鼠上頸神經節強直電刺激後的後期放電之影響

摘要


用六甲松銨處理之離體大白鼠上頸神經節,發現由強直電刺激後自節後之神經所引發的強直電刺激後的後期放電之促進作用,可保持三十分鐘之久。長時期的缺糖處理會使這強直電刺激後的後期放電之促進作用消失。倘若在六十五分鐘缺糖處理後再以葡萄糖處理,這促進作用仍可發生。本實驗之結果表示,由電刺激所產生之節前乙醯胆鹼分泌量與強直電刺激後之後期放電之促進作用有關。

The post-tetanic enhancement of evoked afterdischarge elicited from the postganglionic nerve of isolated rat superior cervical ganglion in the presence of hexamethonium was shown to last for at least 30 min. Continuous glucose deprivation eliminated the post-tetanic enhancement; however, the latter phenomenon could occur if glucose was replaced after the 65-minuteglucose-free incubation. The result suggests that the post-tetanic enhancement process might be associated with the preganglionic acetylcholine content available for the stimulus-induced release.
