一、肺癌细胞免疫学研究 1.细胞免疫机能:肺癌与其它肿瘤一样,当肿瘤增大超过某一限度后机体的细胞免疫机能就要低落。但在肿瘤的早期、发展过程中直到治愈后的一个时期,细胞免疫却始终存在。下面分述肺癌患者免疫机能的检查方法及对其结果的评价。藤田昌史及妹尾纪具等分别对52名和81名肺癌患者在治疗前作淋巴细胞转化试验,并对比化疗、放疗前后的变化,结果表明肺癌患者淋巴细胞转化率低于健康人,并随病情进展有下降的倾向。似说明可用于鉴别胸部X线出现异常阴影的其他疾患。吉田宪基等对比了肺癌与肺结核的淋巴细胞转化率,前者在早期即低落,而后者不见低落。另外,在培养正常人淋巴细胞时,加入肺癌患者的血清可见明显抑
First, lung cancer cell immunology 1. Cellular immune function: lung cancer and other tumors, when the tumor increases beyond a certain limit, the body’s cellular immune function will decline. However, cellular immunity is always present during the early stages of tumor development and during the period after the cure. The examination methods for the immune function of lung cancer patients and the evaluation of their results are described below. Fujita Masaaki and Mei Meiji et al. performed a lymphocyte transformation test on 52 patients and 81 lung cancer patients before treatment, and compared the changes before and after chemotherapy and radiotherapy. The results showed that the lymphocyte transformation rate of lung cancer patients was lower than that of healthy people and progressed with the disease. The tendency to decline. Illustrates other disorders that can be used to identify abnormal shadows on the chest X-ray. Yoshida Kenji et al. compared lymphocyte transformation rates between lung cancer and tuberculosis, the former being low early and the latter not being low. In addition, when culturing normal human lymphocytes, the serum of patients with lung cancer was significantly inhibited
