目的观察不同浓度盐酸羟甲唑啉对体外培养的人钩突黏膜纤毛细胞纤毛运动的影响。方法采用组织块培养法,观察在加有羟乙基哌嗪乙磺酸[4-(2-hydroxyethyl)-1-piperazineethanesulfonic acid,HEPES]的Hank平衡盐溶液(Hank balanced salt solution,HBSS)、0.25、0.50、1.00和2.00g/L的盐酸羟甲唑啉作用下,体外培养人鼻腔纤毛细胞的纤毛摆动频率(ciliary beat frequency,CBF),并进行配对分析。结果①CBF在HBSS中20min内无显著性变化(F=0.098,P=1.00);②0.25g/L盐酸羟甲唑啉组在20min内与加药前CBF无明显变化,差异无统计学意义(F=0.124,P=1.00);③0.50g/L盐酸羟甲唑啉组与1.00g/L盐酸羟甲唑啉组类似,CBF轻微升高,并在1~2min内达到高峰,保持3~4min后,CBF开始缓慢下降,在测量最后达到最低值,但0.50g/L盐酸羟甲唑啉组与加药前相比,差异无统计学意义(F=2.94,P=0.05);1.00g/L盐酸羟唑啉组较加药前CBF降低,加药16min后,差异有统计学意义(F=3.78,P=0.00);④2.00g/L盐酸羟甲唑啉组CBF在最初3min保持稳定,然后持续下降,差异有统计学意义(F=5.69,P=0.00);⑤各组在加药后的最大增加值,差异无统计学意义(F=0.85,P=0.50);加药后的最大下降值在1.00和2.00g/L的CBF明显降低,差异有统计学意义(F=23.74,P=0.00)。结论0.25~2.00g/L的盐酸羟甲唑啉对体外培养的人鼻腔纤毛细胞的纤毛运动存在一定浓度依赖性的抑制作用,且随着药物浓度的增加,抑制作用逐渐增强;0.50g/L盐酸羟甲唑啉可能更适用于临床应用。
