【摘要】 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。更多还原

【Abstract】 Germ cells of testes,ovaries and seminal receptacles of Paragonimus west-ermani of Suifenhe and Paragonimus pulmonalis of Kuandian were prepared byair drying method and observed with phase contrast microscope.A large numberof spermatozoa were observed in the seminal receptacle of P.westermani ofSuifenhe,but no spermatozoon were observed in that of P.pulmonalis of Kuandian.Spermatogenesis in P.westermani of Suifenhe was normal andmeiotic figures was observed.The chromosome number n=11,2n=22 in P.pulmonalis of Kuandian almost all of spermatogenesis might stop at the 32cells stage and neither meiosis nor spermateleosis was observed.The chromo-some number,3n=33.更多还原
