[The effect of electroacupuncture on the function of the partially denervated bladder in rabbits].
Experiments were done with male rabbits (2.5-3.0 Kg). The postganglionic fibers from bilateral pelvica ganglia to the bladder were excised partially and resulted in reversible retention urine. The pressure-volume curve of bladder and volume of residual urine was measured at the third day, sixth day, thirteenth day, twentieth day and twenty-seventh day after the operation of denervation and compared with preoperation respectively. The rabbits were divided into two groups at random. In electroacupuncture group, immediately after the operation of denervation, the intradermal needles were implanted in derma of bilateral "Subcortex" auriculopoint. Before each measurement electroacupuncture at these points and bilateral "Shenshu" (somatic point) was given for 10 minutes. In control group, the operation of denervation was undergone as well but did not be implanted the needle and given electroacupuncture. The results showed that, before the operation a smooth or slowly uniform rising wave appeared on the pressure-volume curve of bladder and only a peak repeated on this background at an instant every injecting water. But after the operation, due to losing of control of parasympathetic nerve partially the pressure-volume curve of bladder appeared ascending step wave evidently after every injecting water. The bladder volume and the residual urine increased evidently. The differences between before and after the operation were statistically significant (P < 0.05). It showed that, after denervating partially the adaptation of the rabbits' bladder was decreased. But on the third day and the sixth day after operation the residual urine decreased more evident in electroacupuncture group than in control group (P < 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)
