我们曾观察了不同剂量~(60)Co γ射线对人蛔虫卵发育和感染力的影响。蛔虫卵的来源,一是受染者的粪便,二是从尸检时所得蛔虫子宫分离出来的虫卵,将后者分为两份,其中一份虫卵用安替佛明脱去蛋白膜。用~(60)Co μ射线照射单细胞期虫卵或感染性虫卵。照射条件:距离40公分,剂量率每分钟100伦,总剂量5～120千伦。照射后培养于30℃。每隔3～7日 We have observed the effects of different doses of ~ (60) Co γ-rays on the development and infectivity of human Ascaris eggs. The source of roundworm eggs, one is the infected feces, the second is from the autopsy worm isolated from the womb uterus, the latter is divided into two, one of the eggs with antipyrine take off the protein membrane. Single-stage or inoculated eggs were irradiated with ~ (60) Co μ-rays. Irradiation conditions: a distance of 40 cm, a dose rate of 100 lun per minute, a total dose of 5 to 120 thousand Lun. After irradiation, incubate at 30 ° C. Every 3 to 7 days
