采用流式细胞仪测定T细胞亚群和脾脏B淋巴细胞电泳对应用活化剂HYP协同“425”制剂的日本血吸虫感染的BALB/c小鼠进行细胞和体液免疫机能测定,并与单一用“425”制剂和感染对照动物进行比较。实验结果表明,HYP协同“425”制剂应用后2wk,相当于感染后6wk,CD4+/CD8+淋巴细胞亚群的比值为6.82,显著高于后两组的1.87和1.79,脾脏中B淋巴细胞总频率达75%,高于单一用“425”制剂和感染对照组的62.5%和64.5%,特异性抗体水平(OD均值)为0.55±0.11,分别高于后两组的0.35±0.03和0.37±0.07。应用后3~4wk,相当于感染后7~8wk,CD4+/CD8+比值为1.98~3.47,后两组则分别为1.32~1.59和1.48~1.70,B淋巴细胞数3组均相近,但前组抗体水平(OD均值)的升高率(82.22%~91.18%)仍高于后两组。由此提示,活化剂HYP协同“425”制剂诱导出的抗日本血吸虫虫卵肉芽肿的免疫效应,显著减弱血吸虫虫卵肉芽肿病变是与增强其细胞和体液免疫功能密切相关,具有明显的理论意义,且为进一步探索抗肉芽肿病变提供了重要依据
Flow Cytometry T cell subsets and splenic B lymphocyte electrophoresis BALB / c mice infected with Schistosoma japonicum using activator HYP in combination with “425” were tested for cellular and humoral immune function and compared with single “425 ”The formulation and infection control animals were compared. The results showed that the ratio of CD4 + / CD8 + lymphocyte subsets of HYP in combination with “425” 2wk, equivalent to 6wk after infection, was 6.82, significantly higher than that of the latter two groups (1.87 and 1.79) The overall frequency of B lymphocytes was 75%, higher than 62.5% and 64.5% of the single “425” formulation and the infected control group, and the specific antibody level (OD mean) was 0.55 ± 0.11, Respectively higher than the latter two groups of 0.35 ± 0.03 and 0.37 ± 0.07. After 3 to 4 weeks of application, it was equivalent to 7 to 8 weeks after infection, with a ratio of CD4 + / CD8 + 1.98 to 3.47, while the latter two groups were 1.32 to 1.59 and 1.48 to 1.70, respectively The number of lymphocytes in three groups was similar, but the increase rate of antibody level (OD) in the former group was still higher than the latter two groups (82.22% ~ 91.18%). It is suggested that the activation of HYP in combination with the “425” preparation induced immunity against Schistosoma japonicum egg granuloma, significantly attenuated Schistosoma japonicum egg granulomatous lesions are closely related to enhance their cellular and humoral immune function, with obvious theory Significance, and provide an important basis for further exploration of anti-granuloma lesions
