我们用大白鼠180只,随机分为6组每组30只,编为1—6号。1号组为健康对照,不染毒。2—6号组大白鼠以NO_2250—450ppm 浓度呼吸道染毒4小时。2号组染毒后的病理改变符合终末细支气管炎。实验证明,用NO_2染毒复制成动物毛细支气管炎模型,是比较简便可靠的方法。3—6号组大白鼠染毒后,分四组进行治疗实验研究。治疗72小时期间观察反应,72小时后活杀,对比各组之病理改变。实验证明,临床表现及病理形态之改善都以维生素K_1治疗组为最佳。表现在终末细支气管炎症轻,支气管痉挛者少,毛细血管周围炎,间质
We use 180 rats, were randomly divided into 6 groups of 30 each, compiled No. 1-6. Group 1 as a healthy control, not infected. Rats in Groups 2-6 were exposed to NO 2 2250-450 ppm for 4 hours in the respiratory tract. The pathological changes in group 2 were consistent with terminal bronchiolitis. Experiments show that the use of NO 2 replication into animal bronchiolitis model is relatively simple and reliable method. Rats in groups 3-6 were exposed to four groups for experimental treatment. The reaction was observed during 72 hours of treatment, and killed after 72 hours. The pathological changes of each group were compared. Experiments show that the improvement of clinical manifestations and pathological morphology are the best vitamin K_1 treatment group. Manifested in the terminal bronchiolitis mild, bronchospasm less, peribulbarritis, interstitial
