摘  要:
6头装有瘤胃瘘、十二指肠体外吻合瘘的山羊,颈静脉灌注0.25,0.5,和1.0mol/L丙酸钠和1.0mol/L乙酸钠溶液(pH均为7.4)。记录灌注前后瘤胃运动频率和收缩幅度的变化,部分实验定时采取颈静脉血样,测定血糖浓度。 结果3种浓度的丙酸钠溶液和1.0 mol/L乙酸钠溶液对瘤胃运动频率、收缩幅度均呈抑制效应,抑制的程度随浓度增高而加强,丙酸钠的抑制作用大于乙酸钠,均以灌注结束后的第一个5分钟为最明显。上述抑制作用可在20~40分钟后逐渐恢复,灌注1.0mol/L丙酸钠时,山羊血糖浓度升高,而灌注乙酸钠则无变化。

摘  要:
Six goats filled with ruminal cannual and duodenal reentrant fistula were used. Sodium of propionate or acetate were injeted via a polyethlene catheter inserted into the jugular vein. After infusion the frequencies and amplitudes of ruminal contraction varied with the amount of the infusion dose (propionate 0.25 mol/L, 0.5 mol/L, 1.0 mol/L and acetate 1.0mol/L 50.0 ml pH7.4). During the first five rain. the frequencies of ruminal contraction were reduced to 69%, 25%, 5% and 79%, and the amplitude decreased to 47%, 31%0 6% and 48%, respectively. But these changes would be resumed to normal in 20 to 40 min. The concentrations of plasma glucose of two animals infused with 1.0 mol/L sodium propionate were increased by 109% and 68%, respectively, at 15 min. after infusion but not changed with 1.0 mol/L acetate used.
