采用聚丙烯酰铵凝胶电泳 (PAGE)对西藏山溪鲵 14种组织的乳酸脱氢酶(LDH)同工酶谱系进行了研究 .酶谱带在各种组织中均表现为 5带型 ,14种组织器官的LDH同工酶可分为三种类型 :第一种为LDH1 及H亚基占优势的 ,包括心肌、生殖腺 ;第二种为H基与M亚基含量近乎相等的 ,包括皮肤、脾、肾等 ;第三种为LDH5 及M亚基占优势 ,包括小肠、胃、肝、肺、肌肉、血清、眼、脑等 .并将对西藏山溪鲵组织LDH同工酶种的特异性及组织特异性成因进行了初步讨论“,”The pattems of LDH isozymes of Batrachuperus tibetanus were investigated in 14 different adult tissue skin, small intestine, stomach, liver, ovary, splech, lung, spermary by means of polyacry lamid gel electrophoresis. The patterns of LDH ioszymes of all adult tissue showed a 5 band type and divided into three types. The first, relative content of LDH 1 and H_subunit is high in tissue of heart and gential gland; second, the elative content of H_subunit and M_subunit is nearly equivalence in tissue of skin, spleen and kideny: the third, the relative content of LDH 5 band and M_subunit is high in other tissue. The paper also discussed the specificity of LDH isozymes of Batrachuperus tibetanus .
