【摘要】 本文观察52例健康老年人外周血淋巴细胞酸性非特异性酯酶(ANAE)反应类型,并与中年组(44例),青年组(58例)作比较。实验结果:老年组ANAE总阳性率(68.5±7.7％)显著低于青年组(76.0±4.1％),P<0.01。在ANAE反应类型中,圆点状颗粒型:老年组(54.5±7.1％)低于中、青年组(59.9±4.1％、65.0±3.7％),P值均<0.01;散在颗粒型:老年组(11.8±3.5％)高于中、青年组(8.6±2.2％,8.3±1.7％),P值均<0.01。更多还原

【Abstract】 ANAE total positive rate and the positive rate of different reactive patterns in peripheral blood lymphocytes of 52 aged persons in good health were determined with ANAE technique and compared with those in 44 middle-aged persons and 58 young subjects. The results showed that ANAE total positive rate significantly decreased in aged people when compared with the young subjects(p<0.01 ). Dot-like granular patterns in aged people were markedly lower than those of middle-aged persons and young subjects. The scattered granular patterns in aged people significantly increased as compared with those in control group. It indicated that peripheral blood Tμ cells in aged people decreased and Tγ cells increased. It was suggested that the decreased dot-like granular patterns were chiefly those with 4 granulae and over, whereas the increased scattered granular patterns appeared as diffuse reactive patterns. It was thought that this classified method was found to be better in exhibiting various changes of lymphocytes ANAE reactive patterns in aged poeple.更多还原
