The experimental findings showed that hydrocortisone effect on metabolism of hexosamine-containing biopolymers of the stomach was dose-dependent. When administered in a small dose (0.2 mg/kg body weight) it increased the activity of biosynthesis of hexosamines, which are necessary for the formation of hexosamine-containing biopolymers, and also increased the total content in the gastric wall of biopolymers, glycosaminoglycans and glycoproteins soluble in perchloric acid. Administration of a large dose of the hormone (50 mg/kg) produced opposite changes in the studied tissue. In patients with peptic ulcer of the stomach and duodenum, exacerbation of which occurred against the background of stress-induced hypercorticosteroidemia, there was observed a decrease of glycosaminoglycan content in the gastric juice and mucosa. A decrease of hexosamine content in glycoproteins was noted.
实验结果表明,氢化可的松对胃中含己糖胺生物聚合物代谢的影响呈剂量依赖性。当以小剂量(0.2毫克/千克体重)给药时,它会增加己糖胺生物合成的活性,而己糖胺是形成含己糖胺生物聚合物所必需的,同时也会增加胃壁中可溶于高氯酸的生物聚合物、糖胺聚糖和糖蛋白的总含量。给予大剂量的激素(50毫克/千克)会使研究组织产生相反的变化。在胃和十二指肠消化性溃疡患者中,在应激诱导的高皮质醇血症背景下病情加重,观察到胃液和黏膜中糖胺聚糖含量降低。还注意到糖蛋白中己糖胺含量减少。
