碳素纤维系化学纤维,包括聚丙烯腈纤维和水合纤维素。实验动物系475只雄性大鼠,分为3组:第1组一次气管内注入含50mg聚丙烯腈纤维尘1ml生理盐水混悬液;第2组一次气管内注入含50mg水合纤维素尘1ml生理盐水混悬液;第3组一次气管内注入1ml生理盐水,为对照组。
Carbon fiber based chemical fibers include polyacrylonitrile fibers and hydrated cellulose. Experimental animals 475 male rats were divided into 3 groups: group 1 once intratracheal injection of 50mg polyacrylonitrile fiber dust 1ml saline suspension; the second group of a tracheal injection of 50mg hydrated cellulose dust 1ml of physiology Saline suspension; group 3 intratracheal instillation 1ml saline, as the control group.
