已知粘膜免疫球蛋白A（IgA）的生成主要依靠胆囊收缩素（CCK）的释放，且明显受到糖皮质激素的抑制。作者进行实验以观察经糖皮质激素处理后鼠的粘膜IgA系统对CCK的反应。取雌性Fisher鼠分成三组：（1）对照组，给0．9％氯化钠皮下注射，实验期前禁食4小时；（2）Dex组．给地塞
It is known that the production of mucosal immunoglobulin A (IgA) is mainly dependent on the release of cholecystokinin (CCK) and is markedly inhibited by glucocorticoids. The authors conducted experiments to observe the response of the mucosal IgA system to CCK in mice treated with glucocorticoid. Female Fisher rats were divided into three groups: (1) control group, subcutaneous injection of 0.9% sodium chloride, fasting for 4 hours before the experimental period; (2) Dex group.
