摘要:

为掌握哲罗鱼、白点鲑和美洲红点鲑血液学原始数据,测定了哲罗鱼、白点鲑和美洲红点鲑血液生理、生化指标,以及在5.75 /S,9.6 /S、11.5 /S、23.0 /S、46.0 /S、115.0 /S、230.0 /S 7个切变率(γ)全血粘度和230 /S切变率血浆粘度;将3种鱼在不同切变率下的全血黏度拟合成逆函数回归曲线,其全血质量分数都呈典型幂函数变化,其曲线回归方程分别为:哲罗鱼y=12.328 x-0.135 3,R2=0.9917;白点鲑y=7.894 2x-0.104 6,R2=0.9979;y=7.505 9x-0.106 2,R2=0.9931。统计分析表明:3种鱼Fb值呈显著性差异P﹤0.05;Tp差异不显著(P>0.05),但存在大小关系:白点鲑>美洲红点鲑>哲罗鱼;红细胞聚集性指数(A1、A2)相互之间差异不显著(P>0.05),白点鲑与美洲红点鲑之间红细胞刚性系数差异不显著(P>0.05),均与哲罗鱼呈显著性差异(P<0.05)。

Abstract:

Blood physiological-biochemical indices in Hucho taimen, Salvelinus leucomaenis and Salvelinus fontinalis were determined . The whole blood viscosity was determined at seven shear rates of 5.75 /S,9.60 /S,11.50 /S,23.0 /S,46.0 /S,115.0 /S,230.0 /S while plasma was at the shear rate of 230 /S. Regression curve of inverse function was built by the result of the whole blood viscosity at different shear rates. It showed that the whole blood viscosity had a typical power function change and the curvilinear regression equation was that Hucho taimen y = 12.328 x-0.1353,R2=0.9917;Salvelinus leucomaenis y = 7.894 2x-0.104 6,R2 = 0.997 9;y = 7.505 9x-0.106 2,R2 = 0.993 1. The statistical analysis showed the 3 fishes had significant difference in the value of Fb P﹤0.05, but not in that of Tp(P>0.05). The relationship of the Tp value in different fishes was Salvelinus leucomaenis > Salvelinus fontinalis > Hucho taimen. There was no obvious difference in the index of erythrocyte aggregation (A1、A2)of the 3 species of fish(P>0.05) so as the rigidity coefficient of erythrocyte between Salvelinus leucomaenis and Salvelinus fontinalis. But they all had significant difference from the rigidity coefficient of erythrocyte of Hucho taimen.
