染尘大鼠和未染尘大鼠肺泡巨噬细胞数量有明显的差别,前者平均值为169.2×10~6(26只大鼠),后者平均值为38.1×10~6(33只大鼠),两者差异非常显著(t=5.82)。不同染尘时间肺泡巨噬细胞数量的动态变化:染尘后16、33、67、90和130天分别为57.8、163.9、102.9、175.1和347.4×10~6个,与未染尘大鼠相比均有显著差异。将染尘动物按肺湿重分为<4g、4～5g、>5g组,每组动物肺泡巨噬细胞均值各为58.6(6只
The number of alveolar macrophages in dyed rats and non-dyed rats were significantly different with the mean of 169.2 × 10 ~ 6 (26 rats) in the former and 38.1 × 10 ~ 6 in the latter (33 large Mouse), the difference between the two is very significant (t = 5.82). The dynamic changes of the number of alveolar macrophages at different dying time were 57.8, 163.9, 102.9, 175.1 and 347.4 × 10 ~ 6 at 16, 33, 67, 90, Than the significant difference. The animals were divided into <4g, 4 ~ 5g,> 5g groups according to lung wet weight. The average value of alveolar macrophages in each group was 58.6 (6
