Intraperitoneal injections of recombinant human granulocyte-macrophage colony stimulating factor (rh-GMCSF, 50 micrograms/kg-1 daily) or interleukin-3 (rh-IL3, 50 micrograms kg-1 daily) for two days, induced an increase in the percentage of bone marrow and pulmonary airway eosinophils in the guinea-pig. In addition, rh-IL3-treated animals exhibited an increase (21%) in blood neutrophils. Exposure of guinea-pigs to an aerosol of platelet activating factor (PAF) gives rise to a selective pulmonary eosinophil accumulation, maximal at 48 h. The eosinophilic response to PAF was significantly enhanced in rh-GMCSF-treated guinea-pigs but was suppressed in rh-IL3-treated animals.
腹腔注射重组人粒细胞巨噬细胞集落刺激因子(rh-GMCSF,每日50微克/千克)或白细胞介素-3(rh-IL3,每日50微克/千克),连续两天,可使豚鼠骨髓和肺气道嗜酸性粒细胞百分比增加。此外,经rh-IL3处理的动物血液中性粒细胞增加(21%)。豚鼠暴露于血小板活化因子(PAF)气雾剂中会导致选择性肺嗜酸性粒细胞积聚,在48小时时达到最大值。在经rh-GMCSF处理的豚鼠中,对PAF的嗜酸性粒细胞反应显著增强,但在经rh-IL3处理的动物中受到抑制。
