[Preliminary observation on effect of electroacupuncture on myocardial metabolism in fasting dogs]

It was observed in the study that effect of electroacupuncture (EA) on energy and oxygen metabolism of myocardium in fasting dogs. 28 healthy mongrel dogs were divided into control and electroacupuncture (EA) group randomly. All the dogs were used in the experiment after fast of 7 days, and during the fasting the dogs were fed with water. The result shows that before EA, the quantity of myocardial uptake of free fatty acid (FFA) and glucose and myocardial consumption of oxygen in control group have not marked difference from that in EA group respectively (P greater than 0.05). Myocardia uptake of FFA in EA group was obviously decreased than that in control group after EA on Pishu and Zhongwan points (P less than 0.05) and myocardial uptake of glucose in EA group was enhanced in comparison with that in control group (P less than 0.05). After removing needles, myocardial uptake of FFA was reduced in contrast to that before EA in EA group with statistical significance (P less than 0.05). Myocardial consumption of oxygen showed a depressing tendency after EA in EA group. but after removing needles, the data of myocardial consumption of oxygen had no difference from that before EA in EA group (P greater than 0.05) and there was not different too in comparison of all the corresponding data between the EA and control group separately. The results shows that the state of myocardial metabolism in fasting dogs could be improved by EA such as myocardial uptake of glucose was enhanced and myocardial uptake of FFA was reduced.(ABSTRACT TRUNCATED AT 250 WORDS)
