粪便用10%福马林固定后,经铜筛及尼龙绢筛去渣集卵,继之用氢氧化钠消化并自然沉淀可使血吸虫卵的检获率提高,且虫卵外形正常结构清晰。与改良醛醚浓集法及甘油玻纸透明法对比,均较后二者优越。 After the stool was fixed with 10% of Fmalin, the eggs were screened through a copper sieve and a nylon sieve to collect the eggs, followed by digestion with sodium hydroxide and natural precipitation to improve the seizure rate of the eggs of the schistosomes, and the normal structure of the eggs was clear. Compared with the modified aldehyde ether concentration method and the transparent method of glycerol glass, both were superior to the latter two.
