近年来,恩加米兰地区曼氏血吸虫感染病例剧增,因此从1985年4月开始实行地区范围的控制措施。随着这个措施的执行,对该地区的学龄儿童进行了曼氏血吸虫感染度与肝脾肿大之间关系的研究。在年龄为6～19岁的373名学生中收集了367份粪便标本,采用Kato玻璃纸粪便厚涂片法进行检查,其中达到实验要求的有354份。计数粪便中的血吸虫卵,以每克粪便所含的卵数(epg)表示。此外,对317名学生进行临床检查,用锁骨中线肋缘下(MCL)及剑突
In recent years, the incidence of Schistosoma mansoni infections in the Ngamran area has soared, starting from April 1985 onwards with district-wide control measures. With the implementation of this measure, the study on the relationship between the infection rate of S. mansoni and hepatosplenomegaly in school-age children in this area was conducted. A total of 367 stool specimens were collected from 373 students aged 6 to 19 years using a smear thick smear of Kato cellophane, of which 354 were required to meet the experimental requirements. Count the schistosome eggs in the stool, expressed as the number of eggs per gram of stool (epg). In addition, 317 students were clinically examined with the midline claw margin (MCL) and the xiphoid process
