1977年10月我们对省八机局高原机械厂肺吸虫病流行情况进行了调查,现将结果报告如下。对象及方法一、调查对象:以该厂职工及家属中吃蟹者为调查对象,不包括未吃蟹者。二、调查方法 (一)肺吸虫病皮肤试验。肺吸虫抗原由四川省寄生虫病研究所和四川医学院寄生虫病教研室供给,用1:2000肺吸虫成虫抗原作皮内试验,注入0.03毫升(丘疹直径为4毫米),注射后15分钟观察反应。皮肤试验阳性反应的标准:丘疹的平均直径小于13毫米,为阴性反应,丘疹大于13毫米为阳性反应。丘疹13—21毫米,红晕小于25毫米(+);丘疹13—21毫米,红晕大于35毫米(++);丘疹在21毫米以上,红晕小于50毫米(+++);丘疹在21毫米以上,红晕大于50毫米(++++)。
In October 1977, we conducted a survey on the prevalence of paragonimiasis in the Plateau Machinery Plant of the Provincial Bureau of Eight, and the results are reported as follows. Subjects and methods First, the survey: Crab workers in the factory workers and their families as the survey, did not include crabs who did not eat. Second, the survey method (a) Paragonimiasis skin test. Paragonimus antigen was supplied by the Parasitic Diseases Institute of Sichuan Province and the Parasitic Diseases Unit of Sichuan Medical College. An intradermal test with 1: 2000 paragonimiasis adult antigen was used to inject 0.03 ml (4 mm in diameter) of the papules and observed 15 minutes after injection reaction. Skin test positive reaction standard: the average diameter of the papules is less than 13 mm, a negative reaction, papules greater than 13 mm for the positive reaction. Papules 13-21 mm, flush less than 25 mm (+); papules 13-21 mm, flush greater than 35 mm (++); papules 21 mm above, flush less than 50 mm (+++); papules above 21 mm , Flush more than 50 mm (++++).
