本工作用小白鼠进行急性实验,以炭末胶液在小肠内推进距离为指标,研究了泥炭腐植酸钠对胃肠推进运动的影响。实验结果表明: 1.对照组小鼠腹腔注射生理盐水,胃肠内炭末胶液在20分钟的推进距离为小肠全长的69.4％。腹腔注射泥炭腐植酸钠30分钟后,再向胃内灌入炭末胶液,20分钟后的推进距离显著减少,表明泥炭腐植酸钠对胃肠推进运动有抑制作用。在一定剂量范围内(0.5～20毫克/公斤),这一抑制作用与泥炭腐植酸钠的剂量有依赖关系。阀剂量为0.5毫克/公
In this study, mice were used for acute experiments, and the distance of the charcoal glue in the small intestine was used as an index to study the effect of sodium sphagnum humic acid on gastrointestinal propulsion. The experimental results showed that: 1. The mice in the control group received intraperitoneal injection of saline, and the advancing distance of the intragastric carbon emulsion at 20 minutes was 69.4% of the total length of the small intestine. After 30 minutes of intraperitoneal injection of peat humic acid sodium, carbon paste was poured into the stomach. The distance of advancement after 20 minutes was significantly reduced, indicating that peat humic acid sodium has inhibitory effects on gastrointestinal propulsion. Within a range of doses (0.5 to 20 mg/kg), this inhibition is dependent on the dose of peat humic acid sodium. Valve dose is 0.5 mg/metric
