The introduction of 25 mg of a new protein antigen into the diets of mice produced transient increases in PVP clearance which reached a maximum 60 hr after the change of diet and had disappeared by 4 days. At the same time the immune responsiveness to unrelated antigens given parenterally was also raised transiently, reaching a peak 5 days following the change and disappearing by 7 days. In contrast the responsiveness to the fed antigen was diminished.
给小鼠饮食中添加25毫克一种新的蛋白质抗原,会使聚乙烯吡咯烷酮(PVP)清除率出现短暂升高,在饮食改变后60小时达到峰值,并在4天后消失。与此同时,对通过非肠道途径给予的无关抗原的免疫反应性也会短暂提高,在饮食改变后5天达到峰值,并在7天后消失。相比之下,对喂食抗原的反应性则降低。
