RESUMEN
A total of 55 cases of advanced schistosomiasis patients combined with Ⅲ-grade hepatic fibrosis and ascites were randomized into a splenectomy group and non-splenectomy group. The peripheral vein blood phlebotomized from these patients were detected for leucocytes, hematids, thrombocytes, acidophils, glutamic-pyruvic transaminase,alkaline phosphatase,albumin, total bilirubin,three-type precollagen, fore-type collagen, hyaluronic acid, IgG, IgA, C_3, C_4 and the sub-group of lymphocytes such as CD3、CD4、 CD8 、CD56 + 16. There were no significant difference on hepatic function and the level of hepatic fibrosis between the groups above metioned. It could be found that leucocytes, thrombocytes, IgG, IgA, CD56 + 16 increased while CD3, CD4, and albumin decreased in the splenectomy group. In conclusion, leucocytes and thrombocytes increase after splenectomy, cytoimmunity declines and humoral immunity enhances.
