过去的研究证明谷氨酸能提高噬尘细胞对粉尘损伤作用的抵抗力,本文使用细胞化学的方法对这一问题进行研究,并同时与P_(204)(Polyvinylpyridineoxide)做比较。各组大鼠腹腔均注入100 mg石英粉尘。第Ⅰ组动物于实验前3天和实验过程中饮用1.5％谷氨酸生理盐水溶液,并将含50 mg谷氨酸的生理盐水溶液与粉尘同时注入腹腔;第Ⅱ组只饮用纯生理盐水;第Ⅲ组与粉尘同时腹腔注入分子量80,000的P_(204) 10mg,24小
Previous studies have shown that glutamic acid can improve the resistance of dust-dust cells to dust damage. In this paper, cytochemistry was used to study this problem and compared with P (204) (Polyvinylpyridineoxide). Each group of rats were injected with 100 mg of quartz dust in the abdominal cavity. Animals in Group I were given 1.5% glutamate saline solution three days before the experiment and during the experiment, and physiological saline solution containing 50 mg of glutamic acid was injected into abdominal cavity simultaneously with dust. Group II only received pure saline; The third group was injected intraperitoneally with P_ (204) 10mg, 24 hours of 80,000
