采用噻唑蓝（ＭＴＴ）比色法~［１］研究了鹭鸶咯口服液对小鼠淋巴细胞的活化作用。结果表明，在一定药物浓度范围内，８％（４８ｍｇ／ｋｇ）、１６％（９６ｍｇ／ｋｇ）、到３２％（１９２ｍｇ／ｋｇ）三个药物浓度或剂量，在体内外对小鼠淋巴细胞活化作用均显著，亦无毒性。从而提示临床上使用该药物时，应考虑其对免疫功能的激活作用及间接抗菌作用，适量提高其药物浓度，增强其药物疗效，以达到充分发挥其药物作用。 MTT colorimetric method[1] was used to study the activation of lymphocytes in mice by the oral solution of harringtonine. The results showed that within a certain range of drug concentrations, 8% (48 mg/kg), 16% (96 mg/kg), and 32% (192 mg/kg) of three drug concentrations or doses activate lymphocytes in mice in vitro and in vivo. The effects are significant and non-toxic. This suggests that when using the drug clinically, it should consider its activation and indirect antibacterial effect on immune function, increase its drug concentration, and enhance its drug efficacy, so as to fully exert its drug effect.
