3小时童虫在含病兔血清、补体和中性粒细胞的培养系统(ISCN)中培养48小时后,约60％的童虫体表有中性粒细胞附着,其中50.8％的童虫已死亡,含病兔血清不含补体(ISCN)、含正常小鼠血清及补体(NSCN)或含正常血清不含补体(NSN)的培养系统中,中性粒细胞粘附童虫体表较少,童虫的死亡率亦低。24小时童虫在ISCN中培养48小时后,中性粒细胞对童虫的附着及童虫死亡率均逊于3小时童虫。在ISCN中,中性粒细胞对72小时童虫几不附着。以中性粒细胞介导的杀死3小时童虫的作用依赖于抗体的存在,但不完全依赖于补体。
About 3 hours later, after about 48 hours of incubation in the serum-containing rabbit serum, complement and neutrophil culture system (ISCN), about 60% of the schistosomiasis has neutrophil attachment, of which 50.8% In the culture system of dead, diseased rabbit serum containing ISCN, normal mouse serum and complement (NSCN) or normal serum containing no complement (NSN), neutrophil adhesion was less , The mortality rate of squirrels is also low. Neutrophil attachment to juvenile worms and sibling mortality after 24 hours of incubation at 24 hours in the ISCN were both less than those of the 3-hour siblings. Neutrophils do not attach to 72-hour-old schistosomiasis in ISCN. Neutrophil-mediated killing of 3-year-old squirrels depends on the presence of antibodies, but not on complement.
