六脉穴埋线对藏系绵羊心肌电位、瘤胃肌电位及瘤胃张力的影响

Effect of catgut embedding in the Liumai acupuncture point on myocardial potential,myoelectric potential and tension in the rumen of Tibet sheep

为调整西藏反刍动物的生理功能,干预高原环境对动物的不利影响,提高牛羊对饲草的高效利用。试验通过六脉穴位埋线,对试验羊只埋线前后进行心电图、胃肠电及胃内张力等进行描记,结果发现六脉穴埋线具有促进藏系绵羊血液循环和缓解心肌过载负荷,调节心电轴右偏达40°的作用;通过对瘤胃肌电图分析,埋线后VPP和RA明显降低,瘤胃内张力降低1/3。结果表明,六脉穴埋线具有缓解右心室肥大,降低瘤胃张力,改善藏系绵羊的胃肠和心血管功能,保障饲草在瘤胃中充分的消化时间。

One of the purposes for the improvement of forages efficient utilization in rumens was to adjust the physiological function of ruminant in Tibet, and to improve the disadvantage influences under the altitude environment. The electrocardiography, rumen electromyography and tension in the rumen were drawn the before and after catgut embedding in the liumai acupuncture point to the Tibet sheep. The result showed that catgut embedding in the Jiumai acupuncture point could promoted the blood circulation, alleviated the overload of myocardial and remedied the right deviation of heart electrical axis up to 40°. The VPP and RA of rumen were significantly lower and the tension of rumen decreased 1/3 after catgut embedding. The result indicated that it could relaxed the right ventricular hypertrophy, reduced the tension of rumen,improved the function of gastroin- testinal tract and blood circulation,ensured sufficient time to digest the forage in rumen.
