用相差显微镜及空气干燥法对黑龙江省绥芬河和辽宁省宽甸卫氏并殖吸虫的生殖细胞进行了活体及核型观察。结果表明,前者受精囊内有大量精子,精子发生、发育过程正常,有减数分裂象。染色体数为2n=22,n=11,属于卫氏并殖吸虫。后者精子发生停留在32个精细胞期,无减数分裂象,无成熟精子,染色体数为3n=33,属于肺生并殖吸虫。 The germ cells of Paragonimus westermani in Suifenhe, Heilongjiang Province and Paragonimus westermani were observed in vivo and karyotype by phase-contrast microscopy and air-drying method. The results show that the former has a large number of sperm in the seminal vesicle, spermatogenesis, the development process is normal, with meiosis. Chromosome number 2n = 22, n = 11, belongs to Paragonimus westermani. The latter sperm occurred in 32 sperm cells, without meiosis, immature sperm, chromosome number 3n = 33, belonging to pulmonary Paragonimus.
