本文研究了NO_2急性暴露对由绵羊红血球引起的小鼠初次体液抗体应答的影响。作者用BALB/C小鼠,6—9周龄,急性暴露5ppm、20ppm和40ppm的NO_2各12小时后,只有40ppm组动物有死亡,死亡率为7.8％(38只死亡3只)。20ppm、5ppm组动物均无死亡。40ppm暴露1、2天后,体重明显下降,4天后恢复到原 This article studies the effects of acute exposure to NO 2 on the initial humoral antibody response in mice induced by red blood cells in sheep. The authors reported that only 40 ppm of the animals died with a mortality rate of 7.8% (three of 38) after 12 hours of 6- and 9-week-old BALB / C mice, acute exposure of 5 ppm, 20 ppm and 40 ppm NO2. 20ppm, 5ppm group of animals did not die. After 1, 2 days of 40ppm exposure, the body weight decreased obviously and recovered to the original after 4 days
