将日本血吸虫虫卵经尾静脉注入正常小鼠,观察沉积在肺血管床形成的虫卵肉芽肿内淋巴细胞的动态变化。结果表明,注卵后第一天即见淋巴细胞浸润,随后,淋巴细胞均数及其所占反应细胞总数的构成比逐渐增加。酯酶染色结果表明,注卵后10天内酯酶染色阳性细胞高于阴性细胞数,第10天后发生逆转;至第35天时更为明显。 The Schistosoma japonicum eggs were injected into normal mice through the tail vein to observe the dynamic changes of lymphocytes in the egg granuloma formed on the pulmonary vascular bed. The results showed that lymphocytes infiltrated on the first day after injection, and then the composition ratio of the average number of lymphocytes and the total number of reactive cells increased gradually. Esterase staining results showed that esterase-positive cells were higher than negative cells within 10 days after ovulation, and reversed after the first 10 days; it was even more evident on the 35th day.
