OBSERVATIONS ON THE CHANGES OF PLASMA PH AND KALIUM CONTENT AND THE EFFECT OF ACUPUNCTURE ON THEM IN THE RATS WITH HEMORRHAGIC SHOCK

In the present work, the changes of pH and the kalium content of blood and the effects of acupuncturing "Renzhong" on these changes were observed in rats with hemorrhagic shock. The experimental rats were randomly divided into three groups: surgical control group, shocked control group, shocked acupancture group. The blood pH was significantly decreased at maintaining shock for one hour (n = 30), P<0.01; there was no change in surgical control group (n = 15), pH decreased continually with the shock time, (n = 14). But pH tended to going up again after acupuncturing "Renzhong" for 15 min (n = 16). The content of blood kalium was increased at maintainually shock for one hour (n = 26). The content of blood kalium was significantly increased whith the prolonging shocked time (n = 12) or acupuncturing "Renzhong" (n = 14), P<0.05. But there was no clear change in surgical group (n = 15). The results suggested that the acidosis condition was slightly rectified by acupuncture via modulating the respiratory function and reducing the acidic metabolites in blood of the rat with hemorrhagic shock. But the hyperkalemia produced by shock was hardly rectified by acupuncture.
