The influence of water extracts from different organic dusts on the number of free lung cells was studied in short-term exposure experiments. A large increase in the number of leukocytes was found 24 hours after exposure to extracts from cotton and hay. The number of macrophages was not affected. The increase was greater when the dusts were incubated at 37 C and 100% relative humidity prior to the preparation of the extract. This procedure caused an increase in the number of bacteria. When different bacterial species were studied endotoxin-producing strains were found to cause the largest effect.
在短期暴露实验中，研究了不同有机粉尘的水提取物对肺内游离细胞数量的影响。暴露于棉花和干草提取物24小时后，发现白细胞数量大幅增加。巨噬细胞数量未受影响。在制备提取物之前，将粉尘在37℃和100%相对湿度下孵育时，这种增加更为明显。此过程导致细菌数量增加。在研究不同细菌种类时，发现产内毒素菌株的影响最大。
