针刺可以降低体温已经动物实验和临床实践证明,但其作用机理未完全清楚。本工作以家兔视前区——下丘脑前部(PO—AH)温度感受神经元自发放电为指标,观察电针对其放电活动的影响。探讨针刺对体温调节中枢的调整作用。 家兔18只,雌雄不拘,体重1.7—2.3kg,以氨基甲酸乙酯(Ig/kg)静脉麻醉。手术后,兔头固定于立体定向仪上,按Sawayer图谱,将玻璃微电极插入PO—AH(A_(1—3)或L_(1—1.5),H_(+1—3mm)范围内)。用自制的软塑料袋,包裹兔躯干和四
Acupuncture can reduce body temperature has been animal experiments and clinical practice proved, but its mechanism of action is not fully understood. In this study, spontaneous electrical discharges from the preoptic area of the rabbit - the frontal hypothalamic (PO-AH) neurons were used as indexes to observe the effect of electroacupuncture on their discharge activities. Probe into the adjustment effect of acupuncture on the body temperature regulation center. 18 rabbits, male and female, weighing 1.7-2.3kg, intravenous anesthesia with urethane (Ig / kg). After the operation, the rabbit head was fixed on the stereotaxic instrument and the glass microelectrode was inserted into PO-AH (A_ (1-3) or L_ (1-1.5), H_ (+ 1-3 mm)) according to Sawayer’s mapping. Use homemade soft plastic bags, wrapped rabbit torso and four
