手十二井穴刺络放血及电针对家兔脑血流图影响的中枢神经递质机理探讨

本实验采用家兔脑室注射受体阻断剂方法，观察电针及手十二井穴刺络放血对家兔脑血流图的影响，以探讨中枢神经递质及受体在其中所起的作用。结果表明：肾上腺素能神经β受体在针刺影响脑血管的效应中起重要作用，而井穴刺终放血效应受到中枢神经M受体及肾上腺素能神经α受体的双重影响，可能是二者协调作用的结果。

A Study on Central Neurotransmitter Mechanism of the Effect of Puncturing the Superficial Blood Vessel of the Twelve Jing Points of Forepaws and Electroacupuncture on the Rheoencephalogram in Rabbits

This study used a method of injecting receptor blocking agants into ventricles of rabbit's brain to observe the effect of electroacupuncture and blood-letting puncturing at the twelve jing points of forepaws on rabbit's rheoencephalogram and to discuss the effect of central neurotransmitters and receptors in this process. The results were as follows: Adrenergic nerve β-receptor has great effect on the action of the central blood vessel when needling, while puncturing the surperficial blood vessel at the twelve jing point of forepaws to cause bleeding can be effected by central nerve m-receptor and adrenergic α-receptor, the effect may be caused by the two's cooperation.
