输血对抗原表露功能及白细胞介素-2生成水平的影响

作者将0.2ml新鲜的同种异体鼠C57BL/6血输入C3H/HEJ鼠体内,然后分别在1、3、7天处死。另一组C3H/HEJ鼠连续3天被输入0.2ml/天同样上述异体鼠血,7天后处死。然后用D10.G4.1 T辅助细胞克隆测定其腹膜巨噬细胞对抗原的表露功能(antigen presentation function)。用白细胞介素(IL-2)依赖的HT-2细胞系测定刀豆素A刺激的脾细胞上清液中IL-2的活性,即脾细胞产生IL-2的功能。从     

IL-2水平与头颈癌预后的关系

125名头颈癌在手术和/或放疗前,取周围血液进行了淋巴细胞亚群及其体外免疫功能的测定。患者随访4年,结果有49人复发。复发者治疗前的淋巴细胞生成白细胞介素-2(IL-2)的水平(1.51±0.2)明显高于无复发者(1.15±0.2)和正常人(1.06±0.3)。对丝裂素的反应也有增加的倾向。若根据 IL-2水平高低分析28个月左右达一稳定水平的存活率,发现 IL-2水平高(≥1.0)的患者为28％,IL-2水平     

阿米洛利可防止两性霉素B引起的低血钾

霉菌感染是中性白细胞减少患者的重要死因,两性霉素B治疗有效,但有引起严重低血钾的副作用,甚至大量补钾也难于纠正。阿米洛利(amiloride,亦名氨氯吡脒)是保钾利尿剂,能增加尿钠和碳酸氢盐的排泄,并抑制远端结肠对钠的吸收。20名因不同血液病引起中性白细胞减少的患者,随机分成两组。

受微波高频辐射人员外周血5—羟色胺含量的变化

The relationship between 5-HT contents in peripheral blood and power density among workers exposed to microwave or high frequency radiation in the workshops were studied. At the same time, systems and disorder of central nervous system and cardiovascular system were examined. The results of study showed that the average 5-HT content in whole blood for high frequency radiation exposure group was lower than that of the control, but without statistical significance. Value for the microwave exposure group was significantly lower than that of the control (P less than 0.01). The 5-HT content of mechanical maintainers exposed to microwave of high frequency radiation were all lower than the contents of their corresponding control groups (P less than 0.01). But for the mechanic operators as compared with their corresponding control, no significant difference was found (P greater than 0.05). The power density exposed by the maintainers of both tested groups were all higher than that of the operators. The 5-HT contents in the whole blood were inversely proportional to the power density of microwave and high frequency groups. The incidence of neurasthenic syndrome, unsymmetric skin temperature in both limbs and hypotension was higher in the microwave and high frequency radiation groups than that in the control group. The incidence of bradycardia and some abnormal items of electrocardiograph in the microwave group was obviously greater than that in high frequency group, which may be related to different frequency exposed for these two exposure groups. Whether it is related to the contents of 5-HT needs further investigation.
