对山东滨县苏家村民323名,包括男158人,女165人,年令自2至71岁,进行了采用醋钠醛固定法调查肠原虫的尝试。结果查见溶组织内阿米巴感染70人,占受检人数的21.7％;感染其他非致病性阿米巴者:哈门氏内阿米巴93人(28.8);结肠内阿米巴104人(32.2％);布氏嗜碘阿米巴47人(14.6％);微小内蜓阿米巴118人(36.5％)。另有兰氏贾第鞭毛虫22人(7.1％)。关于溶组织内阿米巴的感染率在我国以梁宰(1936)调查抚顺矿工的30.0％为最高。但当时系将哈门氏内阿米巴混同于溶组织内阿米巴一并统计的。故此,应与我们两者合计的50.5％相互比较。如此对比,则该农村之溶组织内阿米巴感染率可能远较前者为高。本次调查之粪便材料,经醋酸钠醛固定液保存后,是在迟延五个月后进行镜检的。标本大都仍可保留可资鉴别的形态结构。从固定效果衡量仍是令人满意的,不失为面向广大农村开展肠原虫调查的良好方法之一。
A total of 323 villagers, including 158 males and 165 females, aged from 2 to 71 years were enrolled in the village of Sujia, Bin County, Shandong Province. Attempts were made to investigate Enterobius spp. The results showed that 70 cases of Entamoeba histolytica infection, accounting for 21.7% of the number of subjects; infected with other non-pathogenic amoeba were: 93 (28.8) Enterobacter amoebau; 104 (32.2%), 47 (14.6%) were buteoadhabdine amoebae, and 118 (36.5%) were small investegium. In addition, there were 22 Giardia lamblia (7.1%). Infection rate of Entamoeba histolytica in our country to Liang Zai (1936) survey of 30.0% of Fushun miners for the highest. However, the Department of Amoeba hamones will be mixed with Entamoeba histolytica statistics. Therefore, 50.5% of our total should be compared with each other. In this comparison, the rate of Entamoeba histolytica infection in rural areas may be much higher than the former. The stool material of this investigation, after preservation by sodium acetate aldehyde fixative, was examined microscopically after a delay of five months. Most specimens can still retain identifiable morphological structure. It is still satisfactory to measure the effect of fixation, which is one of the good methods to carry on intestinal protozoan survey in the vast rural area.
