愈疡散的药效学研究

目的:研究愈疡散(獐芽菜、象皮、白及等)抗实验性胃溃疡的作用.方法:采用乙酸烧灼型溃疡模型、应激性溃疡模型、乙醇致胃粘膜损伤模型、幽门结扎型胃溃疡模型观察愈疡散对各型溃疡及胃液量、胃液酸度、胃蛋白酶活性的影响.结果:与空白组相比,愈疡散可抑制溃疡的形成,降低大鼠胃溃疡指数,促进溃疡的愈合,抑制胃液分泌,降低胃液酸度,有降低胃蛋白酶活性的趋势.结论:实验结果与该药临床用于治疗胃溃疡的功效相吻合.

Pharmacodynamics study of Yuyang Powder

AIM: To study the action of Yuyang Powder(Herba Swertiae, Corium Elephantis, Rhizoma Bletillae, etc.) on the experimental gastric ulcer. METHODS: The rat gastric ulcer models were induced by burned acetic acid, irritabillity stimulus, ethanol injure gastric mucosa and pyloric ligation, respectively. The ulcer was obsered and the content of gastric juice, gastric acidity and pepsin were measured. RESULTS: Yuyang Powder could significantly reduce the areas of ulcers, restrain gastric ulcer, promote gastric ulcer heal, reduce gastric juice volume, restrain gastric secretion (in pyloric ligation). CONCLUSION: Yuyang Powder has the preventive and therapeutic in gastric ulcer.
