疟原虫染色的血片标本,常因着色不佳或保存过久褪色,需要重新再染。半个世纪以来,许多寄生虫学工作者不断地改进与研究,但是重染的结果仍很不理想。1985—1990年,我们对此工作进行研究,先后进行共1219次试验,终于获得满意的结果。现报道如下: 材料与方法 1.去掉油迹、污垢及残留的染色痕迹将褪色和着色不佳的陈旧疟原虫染色标本,置于装有二甲苯的染色缸内浸泡10分钟,更换酒精二甲苯(100％酒精与二甲苯各半混合均匀)5分钟,再更换 Plasmodium stained blood film specimens, often due to poor color or save too long fade, you need to re-dyed. For more than half a century, many parasitological workers have been constantly improving and researching, but the results of heavy dyeing are still far from satisfactory. From 1985 to 1990, we conducted a study of this work and conducted a total of 1,219 trials in succession, finally obtaining satisfactory results. Are reported as follows: Materials and methods 1. Remove the traces of traces of oil, dirt and stains will be faded and poorly colored old Plasmodium stained specimens, placed in a dye tank with xylene soaked 10 minutes, replace the alcohol xylene (100% alcohol and xylene half mixed evenly) for 5 minutes, and then replaced
