本文用受体放射自显影、组织化学和电生理学方法，观察了切断后根和辣椒素处理后大鼠脊髓后角内乙酸胆碱受体（AChR）和阿片受体的变化及其与乙酸胆碱酯酶（AChE）和P物质（SP）的关系。结果发现：1．脊髓后角内有ACh敏感神经元：微电泳ACh（IM，ZnA）可使后角痛敏神经元（15个
In this study, we observed the changes of acetylcholine receptor (AChR) and opioid receptors in the dorsal horn of spinal cord of rats after root and capsaicin treatment by means of autoradiography, histochemistry and electrophysiology. Relationship between alkaline esterase (AChE) and substance P (SP). The results showed that: 1. ACh sensitive neurons in the dorsal horn of the spinal cord: ACh (IM, ZnA) microencapsulated acral neurons (15
