Erythromycin Enhances Regulatory T-Cell Responses in a Rat Model of Smoke-Induced Lung Inflammation
Figure 2
Treatment with erythromycin reduces the numbers of inflammatory infiltrates in the lungs of rats. BALF samples were collected from individual rats and the cells were stained with May-Grünwald-Giemsa. The numbers of total inflammatory infiltrates, macrophages, lymphocytes, and neutrophils were analyzed, according to their morphological characters. Data are expressed as mean numbers of individual samples and mean values (lines) for each group (). Group N: rats exposed to regular air without any special treatment; Group C: rats exposed to regular air and were treated with erythromycin; Group S: rats exposed to smoking air and were treated with saline; Group E: rats exposed to smoking air and were treated with erythromycin daily for nine weeks beginning at the forth weeks smoking. *.
