文献上曾报告,谷氨酸可使腹腔巨噬细胞对石英粉尘损伤作用的抵抗力明显升高;本文叙述了谷氨酸对肺泡巨噬细胞抵抗石英粉尘损伤能力的影响。实验用动物为体重160～200g的雄性大鼠,共分4组:第Ⅰ组不吸入石英粉尘,饮用普通水,第Ⅱ组不吸入石英粉尘,饮用由NaHCO_3中和的1.5%谷氨酸液(以上二组自然吸入周围大气中固有的粉尘);第Ⅲ组
It has been reported in the literature that glutamate significantly increases the resistance of peritoneal macrophages to the damaging effect of quartz dust. This article describes the effect of glutamate on the resistance of alveolar macrophages against quartz dust damage. The experimental animals were male rats weighing 160 ~ 200g and were divided into 4 groups: group Ⅰ did not inhale quartz dust, drinking ordinary water, group Ⅱ did not inhale quartz dust, drinking 1.5% glutamic acid solution neutralized by NaHCO 3 (The above two groups naturally inhale the dust inherent in the surrounding atmosphere); Group III
