天然杀伤细胞(NK)是免疫监视肿瘤细胞生长和抵抗微生物感染的最重要的淋巴样细胞。吸烟者和石棉工人常伴有许多的免疫系统异常。作者推测这些状态也能影响NK活性,因此有必要研究不吸烟者、吸烟者和石棉工人外周血的NK活性。本文研究的对象是由70名成人所组成:24名不吸烟者为对照组(男17名,女7名)、10名吸烟者(男6名、女4名)和33名石棉工人为实验组。不吸烟的对照组和吸烟组都是不接触石棉的健康志愿者。全部研究对象都没有使用免疫抑制剂或肿瘤性疾患等。
Natural killer cells (NKs) are the most important lymphoid cells that immunize tumor cells and monitor microbial resistance to infection. Smokers and asbestos workers often have many abnormal immune systems. The authors speculate that these conditions can also affect NK activity, so it is necessary to study NK activity in the peripheral blood of non-smokers, smokers and asbestos workers. The object of this study is composed of 70 adults: 24 non-smokers as control group (17 males and 7 females), 10 smokers (6 males and 4 females) and 33 asbestos workers group. Non-smoking controls and smoking groups were all healthy volunteers who were not exposed to asbestos. All the subjects did not use immunosuppressive agents or neoplastic diseases.
