我们采用噻唑蓝（ＭＴＴ）比色法和小鼠腹腔巨噬细胞吞噬鸡红细胞实验观察了鹭鸶咯口服液对小鼠巨噬细胞的活化作用和吞噬功能的影响。结果表明，在８％（ｇ／１００ｍｌ）和１６％两个药物浓度，该药物对小鼠巨噬细胞均无毒性，且刺激其大量增生。对于巨噬细胞活性的影响，在体内外作用均显著。在８％、１６％、３２％三个药物浓度上，该药物对提高巨噬细胞吞噬功能均有显著作用。 We use thiazolyl tetrazolium (MTT) colorimetric method and mouse peritoneal macrophages phagocytosis of chicken erythrocytes observed Egrettia oral liquid on mouse macrophage activation and phagocytosis. The results showed that at both drug concentrations of 8% (g / 100ml) and 16%, the drug was non-toxic to mouse macrophages and stimulated its proliferation. The effect on macrophage activity was significant both in vitro and in vivo. At 8%, 16%, 32% of the three drug concentrations, the drug has a significant effect on the phagocytosis of macrophages.
