Immune components were investigated in peripheral blood and in spleen and head kidney of autotriploid Salmo trutta f. lacustris, Salvelinus fontinalis, and Salvelinus umbla, and of allotriploid hybrids of S. trutta f. lacustris x Onchorynchus mykiss and S. fontinalis x O. mykiss in comparison to their diploid parents. In peripheral blood the number of lymphocytes was reduced in all investigated autotriploids and in the allotriploid S. trutta f. lacustris x O.mykiss, and the numbers of thrombocytes in autotriploid S. trutta f. lacustris and in both allotriploids. Alternative pathway of complement activity and immunoglobulin concentration were significantly decreased in all investigated auto- and allotriploids, lysozyme activity in autotriploid S. fontinalis and in both allotriploids. In the spleen of the 3 autotriploids the number of erythrocytes was increased, while the number of lymphoid precursor cells was decreased. In their head kidney the erythrocytes numbers were decreased and the numbers of erythropoietic precursor cells and the melanomacrophage centers were increased. Contrary, cytology of spleen and head kidney of the two allotriploid hybrids was similar to diploid controls. Caspase 1, caspase 6, lysozyme, and acid phosphatase activity and immunoglobulin concentration of spleen and head kidney showed specific changes which were related to cytological results. These data indicate alterations in immune system and in lymphoid organs of auto- and allotriploid Salmonidae.

二倍体与自身及异源三倍体鲑科血液、脾脏和头肾免疫成分的差异

研究了外周血和自三倍体鲑鱼的脾脏和头肾中的免疫成分。lacustrisSalvelinus fontinalisSalvelinus umbla,以及S. trutta f.的异源三倍体杂交种。lacustris x Onchorynchus mykiss 和 S. fontinalis x O. mykiss与其二倍体亲本的比较。在外周血中,所有研究的同源三倍体和异源三倍体S. trutta f.中淋巴细胞的数量都减少了lacustris x O.mykiss,以及同源三倍体S. trutta f.中血小板的数量。湖泊并且在两个异源三倍体中。在所有研究的自身和异源三倍体中,补体活性和免疫球蛋白浓度的替代途径显着降低,同种三倍体S. fontinalis 中的溶菌酶活性显着降低并且在两个异源三倍体中。在3个同源三倍体的脾脏中,红细胞数量增加,而淋巴样前体细胞数量减少。在他们的头部肾脏中,红细胞数量减少,红细胞生成前体细胞和黑色素巨噬细胞中心的数量增加。相反,两个异源三倍体杂种的脾脏和头肾的细胞学与二倍体对照相似。Caspase 1、caspase 6、溶菌酶、酸性磷酸酶活性和脾、头肾免疫球蛋白浓度均出现与细胞学结果相关的特异性变化。这些数据表明自身和异源三倍体鲑科的免疫系统和淋巴器官发生了改变。
