在我国流行的两种丝虫(班氏丝虫和马来丝虫),其微丝蚴在人体末稍血液中,均有昼伏夜出的周期性现象,因此对微丝蚴的检出,需在夜晚进行,这对病人和工作人员带来很多不便之处,尤其是大规模的普遍调查,往往受时间限制,每天不能检查更多的居民,为此我们这次在丝虫病研究试点区内,在进行丝虫病流行病学调查的同时,选择部分病例,进行马来微丝蚴周期性出现的一些观察,企图从中找出规律,改变检查时间,有利于今后大规模开展丝虫防治调查工作。今将这次观察的项目和结果综述如下:
Two kinds of filarial epidemic in our country (Bancroftian filariasis and Malay filariasis), the microfilariae in the human body at the end of the blood, have a nocturnal and periodic phenomenon, so the detection of microfilariae , Which needs to be carried out at night. This brings a lot of inconvenience to patients and staff. In particular, large-scale universal surveys are often time-limited and can not inspect more residents every day. Therefore, In the pilot area, during the epidemiological investigation of filariasis, some cases were selected to make some observations on the periodic appearance of microfilariae in order to find out the regularity and change the inspection time, which is beneficial to the large-scale development of silk Pest control survey. The items and results of this observation are summarized as follows:
