Effects of Orally Administered Human Epidermal Growth Factor on Natural and Delayed Healing of Acetic Acid-Induced Gastric Ulcers in Rats

抄録

We examined the effects of orally administered human epidermal growth factor (hEGF) on healing of acetic acid-induced gastric ulcers in rats. hEGF, given twice daily at 30 and 100 μg/kg for 2 weeks or at 100 μg/kg for 4 weeks to rats with ulcers, had no effect on natural healing or the gastric secretion, delayed one caused by indomethacin. Oral hEGF had no effect on basal histamine-stimulated gastric secretion, and stomach weight. These results indicate that oral hEGF has no biological activity on the pathophysiology of the stomach.
