由于日本血吸虫寄生在人体的肠系膜静脉中,所产的虫卵仅有少数能通过肠壁排出体外,诊断比较困难。常用的沉淀浓集和孵化方法,其效率虽比直接塗片法高了很多倍,但一次的检出率仍然不够理想,只能检出60%左右的患者,有些患者需要反复检查7次以上才能确定诊断。因此,寻求新的高效的检查方法有很大的实用意义。张奎等(1962)报导用比重1.40的硫酸锌溶液漂浮检查血吸虫卵,其效果可接近常用的沉淀结合孵化法。我们在张氏等报导的基础上,对漂浮法检查血吸虫卵的效果作了一些观察,以期能推广应用于部队。现将观察结果报告如下。(一)漂浮检查的方法。张氏等(1962)介绍的方法有二:1.离心漂浮法:粪便加水搅匀,经80孔铜筛过滤,置于500毫升尖底量杯中沉淀冲洗二次,然后把约0.5-1毫升的沉渣吸入华氏管中,加水9毫
As Schistosoma japonicum parasites in the human mesenteric vein, the eggs produced by only a small number of excreted through the intestinal wall, the diagnosis is more difficult. Commonly used precipitation concentration and incubation methods, although its efficiency than the direct smear method many times higher, but once the detection rate is still not ideal, only about 60% of patients were detected, and some patients need to repeatedly check more than 7 times To determine the diagnosis. Therefore, it is of great practical significance to seek new and effective inspection methods. Zhang Kui et al. (1962) reported that floating schistosome eggs with a zinc sulfate solution with a specific gravity of 1.40 could be used to achieve the effect of the commonly used precipitation-bound incubation method. Based on the reports of Zhang et al, we made some observations on the effect of flotation on schistosomiasis eggs in order to promote their application to the army. The observations are reported below. (A) Floating inspection method. Zhang et al (1962) describes the method has two: 1. Centrifugal floating method: Add water and stir well, filtered through a 80 hole copper sieve, placed in a 500 ml sharp end of the cup sediment washed twice, and then about 0.5-1 ml The inhalation of sediment Fahrenheit tube, add water 9 milliliters
