近年来的综述指出,锰的化合物能够促使人和实验动物的呼吸道疾病加重。有人统计接触锰尘的矿工,肺炎发病率为2.6%,而非矿工对照人群则仅0.07%,并报导吸入锰尘可引起人和兔的肺炎。本文报导了小鼠吸人二氧化锰(MnO_2)气溶胶后,在空气中传播肺炎杆菌或流感病毒诱发感染,观察小鼠肺组织内锰尘的含量、死亡率、平均存活时间和肺部损害程度。实验用雄性小鼠。气溶胶二氧化锰的纯度为 Recent reviews suggest that manganese compounds can contribute to the increase of respiratory diseases in humans and laboratory animals. Some people who contact with manganese dust miners, the incidence of pneumonia was 2.6%, compared with only 0.07% of the non-mining control population, and reported that inhalation of manganese dust can cause pneumonia in humans and rabbits. In this paper, mice were inoculated with aerosols of manganese dioxide (MnO 2) aerosol and then propagated pneumonia or influenza virus in air to induce infection. The content of manganese dust, mortality, mean survival time and lung damage in mice lung tissues were observed degree. Experimental male mice. Aerosol manganese dioxide purity
