To evaluate the significance of Beryllium-Activated Active Rosette test(BeEa)in the diagnosis and differential diagnosis of chronic pulmonary beryllium disease, the authors studied the beryllium workers of two beryllium plants with BeEa. The lymphocytes of peripheral blood from the patients with chronic pulmonary beryllium disease and the beryllium workers with pulmonary lesions, incubated with beryllium sulphate in vitro at 37℃ for 2 hours, showed a significantly increased percenthge of active rosette forming...

To evaluate the significance of Beryllium-Activated Active Rosette test(BeEa)in the diagnosis and differential diagnosis of chronic pulmonary beryllium disease, the authors studied the beryllium workers of two beryllium plants with BeEa. The lymphocytes of peripheral blood from the patients with chronic pulmonary beryllium disease and the beryllium workers with pulmonary lesions, incubated with beryllium sulphate in vitro at 37℃ for 2 hours, showed a significantly increased percenthge of active rosette forming cells. The optimal concentration of beryllium added was 0.75 μg/ml, the optimal incubation period being 2 hours. The results from Plant A showed that the rosette forming cells were increased by 23.3% (e. g. active rate)in the patients with chronic pulmonary beryllium disease and 18.9% in the beryllium workers with pulmonary lesions. However, there was no increase in those beryllium workers without pulmonary lesions and non-exposed controls. The criteria for BeEa were as follows:activation rate of 19% or more was interpreted as posit- ive, activation rate between 14% and 18% weakly positive, and that below 14% negative. In the light of the above criteria, four of the five patients were grouped as of positive reaction. Out of the 38 beryllium workers with pulmonary lesions 20 were grouped as of positive and 7 weakly positive, whereas the 29 beryllium workers without pulmonary changes, 34 non-exposed controls and 25 patients with silicosis or silicotuberculosis were all negative. The results from Plant B (16 beryllium workers with pulmonary lesions) were similar to those from Plant A. These results suggested that BeEa test be used as one of the indices of the auxiliary and differential diagnosis of chronic pulmonary beryllium disease.

慢性铍肺病人和有肺部病变的铍作业工人的淋巴细胞在体外经铍刺激后,可使活性玫瑰花形成率增高。加入铍浓度以0.75微克/毫升最好,孵育时间以37℃2小时为佳。甲厂慢性铍肺病人的平均激活率为23.3%;有肺部病变的铍作业工人组为18.9%;无肺部改变的铍作业工人组和非铍作业对照组无增高现象。将BeEa结果以阳性(激活率≥19%)、可疑阳性(激活率为14~18%)和阴性(激活率<14%)来表示,则5名慢性链肺病人有4名阳性;38名有肺部病变的敛作业工人中有20名阳性和7名可疑阳性;而无肺部病变的铍作业工人29人,非铍作业正常人34人和矽肺、矽肺结核病人25人,全部阴性。乙厂16名有肺部病变的铍作业工人的试验结果与甲厂相似。结果表明,BeEa试验可作为慢性铍肺的辅助诊断和鉴别诊断指标之一。

The Baiyunebo Mine is a mixed mine which contains iron, rare earth, fluorite and a litte thorium (0.04%). An investigation of cell-mediated immunity of 212 male workers exposed to thorium containing dust at Baiyunebo Mine was carried out. The results revealed that the average values of lymphocytes of peripheral blood in exposed workers were significantly higher and the percentage of E rosette formation were lower than that in the control workers (p<0.05 and 0.001 respectively). The T-lymphocytes count based...

It suggested that higher sensibility among the workers under PHA stimulation would be resulted from the thorium exposure.

本文对215名接触含钍粉尘的工人进行了细胞免疫学调查,发现外周血淋巴细胞数显著地高于对照纽,而E玫瑰花环形成率虽低于对照组,但T淋巴细胞绝对数并不低。两次不同剂量(10、40μg)的PHA皮试亦显示反应增强。结果提示,暴露于含钍粉尘可能对PHA刺激的敏感性增高。

本文观察了油菜蜂花粉及其丙酮提取物对正常和由于免疫抑制剂环磷酰胺、荷瘤及抗淋巴细胞血清所致免疫低下小鼠的免疫增强作用。结果表明,蜂花粉及其丙酮提取物对正常幼年和成年小鼠能提高血清抗SRBC抗体的含量(HC_(50))和增加脾脏空斑形成细胞(PFC)。蜂花粉丙酮提取物对环磷酰胺、荷瘤及抗淋巴细胞血清等所致免疫低下小鼠的血清抗SRBC抗体、定量脾细胞体外分泌抗SRBC抗体(QHS)、脾脏空斑形成细胞(PFC)和特异玫瑰花形成细胞(SRFC)减少均有明显对抗作用。上述结果提示,油菜蜂花粉及其丙酮提取物有免疫增强作用,丙酮提取物可能是该花粉所含一种增强兔疫作用的活性物质。
