旋毛虫各隔离种嗜酸性粒细胞变化的研究

Change of Eosinophile Cells in Pigs Infected with Trichinella Isolates

旋毛虫各隔离种感染猪后 ,其血液中嗜酸性粒细胞显著增多 ,而其它各类细胞无明显变化 ,嗜酸性粒细胞于感染后 7d开始升高 ,1 6d左右达最高峰 ,以后呈逐渐下降趋势 ;猪旋毛虫和旋毛形线虫 (T .spiralis)的嗜酸性粒细胞数量始终高于犬旋毛虫和本地毛形线虫 (T .nativa)。嗜酸性粒细胞增多可作为早期诊断旋毛虫病的重要临床指标之一。

The eosinophile cells increased in their numbers significantly in the pigs infected with Trichinella isolates,however,there was no change in other kind of blood cells.The number of the eosinophile cells started to increase on the day of 7 after infection and reached a peak level on the day 16 postinfection,when it fell gradually there after.However,it was still higher compared with that in the control group.Swine isolate and T spiralis were different from dog isolate and T.nativa on eosinophilosis,the number of the eosinophile cells of swine isolate and T spiralis were higher than that of dog isolate and T.nativa all along.The eosinophilosis can be an indication for the early diagnosis of Tichinellosis.dely in China were studied.The results indicated that compositions of most HMW GS in China wheats are the same as that abroad.But some special HMW GS(SHMW GS)were also found in China wheats.The frequency and characteristics of all of these HMW GS(or combination types)were probed.
