我们从 1992年初采用巴氏法保存钩虫卵 ,并同时采用两种不同方法保存两种虫卵以作比较。厚壳虫卵用中华分枝睾吸虫卵 ,薄壳虫卵用钩虫卵。迄今已观察 8年余 ,镜下见中华分枝睾吸虫卵及钩虫卵仍然如同新鲜标本 ,不但外形没有变化 ,内部构造的卵细胞、四核期卵与桑椹期卵仍然清晰 We used the pasteurization method to keep hookworm eggs from the beginning of 1992 and used two different methods to save the two eggs for comparison. Thick-shell eggs with Chinese branch testis eggs, thin-shelled eggs with hookworm eggs. So far, it has been observed for more than eight years. Microscopically, the Chinese testis and testis remain as fresh specimens, not only the appearance is unchanged, but the internal structure of eggs, tetranucleus eggs and mulberry eggs are still clear
