针刺调节膀胱功能

治疗膀胱疾患

疗效好

方法简便

在国内得到广泛的运用和开展

而且也乐为国外医生所采用

但是对于针刺调整膀胱功能的机理研究资料不多

尤其是涉及到针刺对高位排尿中枢活动的影响报道甚少。有人从临床方面观察到针刺一些穴位可调整膀胱原有的紧张性

Using methods of the electrostimulation

transection and electrolytic destruction of brain and microelectrode exploration

frequency of unit discharge and intravesicular pressure were recorded to evaluate regulation mechanism of acupuncture on pons micturation centre and related function of urinary bladder.All experments were performed in 32 male rabbits in awake

immobilized and artificially respiratory state. 1.Rabbit's vesicomotr area was located in the dorsolateral RF of rostral pons.Simultaneous electrostimulating pons and needling“Ci liao;acupoint might elevate the bladder pressure to a higher level than they were separatly stimulated.But

during bilateral lesion of the above-mentioned area in pons the effect of acupuncture wa reduced to about half of its original value. 2.Cell discharges responding exclusivelly to bladder distension as well as acupuncture were recorded in the micturation centre of pons by microele- ctrode(38 units)

33 units being exciting

and 5 units inhibiting.Most of them changed their discharge tate immediately following needling“Ci liao; acupoint

then

bladder pressure elevated after a latent period of 1.5-2 sec. When unit activity was inhibited by thiopental(i.v.)

the effect of acupu- ncture disappeared.The effect of acupuncture recovered with appearance of unit activity. The results suggested that needling might modulate bladder function prov- ided the high centre is intact

that pons played an important role in the process of acupuncture.It is supposed that effect of acupuncture regulating bladder function was due to afferent input modulating excitation level of mcturation centre in pons

and in turn

affecting the bladder function as well.
