中华鳖肝组织炎性细胞的浸润及其结构

Infiltration and structure of inflammatory cell in the hepatic tissue of Trionyx sinensis

用组织化学和显微及亚显微生物技术，研究了患非寄生性肝病中华鳖（Ｔｒｉｏｎｙｘｓｉｎｅｎｓｉｓ）的外周血、肝静脉血血相变化和浸润肝组织炎性细胞的亚显微结构及其细胞免疫病理反应。结果表明，中华鳖的炎性细胞趋化性强、浸润面广。其剧烈的非特异性细胞免疫反应表现为：嗜中性粒细胞数量多、个体大、结构变化复杂，并在非特异性细胞免疫反应中发挥重要作用，其次是淋巴细胞、Ｋｕｆｅｒ细胞；肝组织中被激活的白细胞在结构和数量上发生显著变化，并在浸润肝组织后聚集、吞噬、消化，发生强烈的细胞免疫反应。红细胞发生渗出性病理反应。

With histochemical method, microscopy and ultrastructure biotechnology, the hemogram changes of peripheral blood and hepatic vein blood in shelled turtle with nonparasitical hepatosis were studied. Meanwhile, the ultractructure of the infiltrated inflammatery cells in hapatic tissue and their cellular immunopathological reaction were observed. The result shows that inflammattory cells can be aroused fast, their chemotaxis are strong and their infitration scope are wide. All these reflect that the cytoimmunity level of shelled turtle is much higher. Among the cells neutrophilie grainy cells are in a large quantity, and their cell structure changes greatly. They play a more important role than lymphocyte and Kuffer cells do in nonspecific immunoreaction. Aroused granulocyte in hepatic tissue and those nonaroused in blood changes obviously in quantity and structure. The cytoimmunological reaction is strong, such as being aroused, emigrating, infitrating, gathering, englobing, digesting. Red-cell has immunopathologic reaction.
