摘要
大鼠喂以5%酪蛋白饲料造成蛋白质营养不良,与喂以20%酪蛋白饲料大鼠比较,观察了血浆蛋白水平,外周血T淋巴细胞亚群及转化反应的动态变化。实验结果表明,血浆前白蛋白、T淋已细胞CD_4亚群及T淋巴细胞转化反应对蛋白质营养不良较为敏感,5%蛋白水平饲料喂养三天后就显著下降,T淋巴细胞转化反应早期下降后尚有反弹现象;改喂20%蛋白水平饲料一周后,血浆蛋白均恢复至正常水平,T淋巴细胞CD_4亚群及转化反应恢复缓慢。
hanges of plasma prealbumin,transferrin and albumin levels, periphe-ral T lymphocyte CD4,CD8 subsets and biastogenesis stimulated by Con A investigated in rats were fed on 5%and 20% casein diets.Plasma preal-bumin,T lymphocyte CD4 subset and blastogenesis were very sensitive to protein malnutrition,They were decreased significant after the rats fed on 5%casein diet for 3 days. However,the T lympbocyte blastogenesis exhibited a remarkabl e rebound shortly after its decline and decreased again thereaf-ter. All plasma proteins returned to normal after the diet had been changed to 20%casein for one week,but the T lymphocyte CD4 subset and blasto一genesis did not restored completely.
