摘 要:目的:观察蜂胶对慢性阻塞性肺疾病患者(chronicobstructivepulmonarydisease,COPD)肺泡肺泡巨噬细胞(alveolarmacrophage,AM)游离钙浓度及其生成的白细胞介素8(IL-8)、一氧化氮的影响。方法:采用支气管肺泡灌洗、细胞培养和荧光指示剂方法,测定AM内钙浓度其生成的IL-8和NO。结果:COPD组患者AM内钙浓度犤(68.26±7.24)nmol/L犦,IL-8犤(29.11±9.78)ng/L犦,一氧化氮犤(27.61±8.64)μg/L犦均高于对照组犤(60.61±6.26)nmol/L,(15.42±6.78)ng/L,(13.99±7.40)μg/L犦(t=11.38~36.42,P<0.01)。脂多糖刺激以后,胞内游离钙浓度、IL-8和一氧化氮均较刺激前增高(t=12.65~32.58,P<0.01)。先加蜂胶孵育AM再加入脂多糖,胞浆内游离钙浓度、IL-8和一氧化氮较仅加脂多糖时减少(t=14.72~25.02,P<0.01)。结论:蜂胶可抑制脂多糖引起的犤Ca2+犦i增加,对脂多糖刺激的IL-8和一氧化氮升高也有抑制作用;可调节AM激活,抑制IL-8、一氧化氮分泌。AIM:To observe the effects of propolis on cytosolic free calcium in alveolar macrophages(AM) and on interleukin-8(IL-8) and Nitrogen monoxide(NO) secretion of them in patients with chronic obstructive pulmonary disease(COPD). METHODS:With the technique of bronchoalveolar lavage,cell culture and the fluorescent indicator, the effect of concentration of free calcium and IL-8,NO of AM were estimated. RESULTS:The concentration of calcium[(68.26±7.24) nmol/L],IL-8[(29.11±9.78) ng/L]and NO[(27.61±8.64) μg/L] increased significantly in COPD,as compared with the control group,in which the ncentration of calcium was(60.61±6.26)nmol/L,IL-8 was (15.42 ±6.78) ng/L and NO was(13.99±7.40) μg/L (t=11.38-36.42,P< 0.01).The concentration of calcium,IL-8 and NO increased after stimulation with lipopolysaccharide(LPS)(t=12.65 to 32.58,P< 0.01). LPS was added after ncubation with propolis,and the concentration of calcium,IL-8and NO decreased than that adding LPS only(t=14.72 to 25.02,P< 0.01). CONCLUSION:Propolis not only restrains calcium caused by lipopolysaccharide,downregulates alveolar macrophages activation but also decreases the elevation of the IL-8 and NO.
