人工养殖不同年龄史氏鲟的血液生化指标

测定了1～5龄5个年龄组的人工养殖史氏鲟血液的总蛋白、血脂、血糖、血清酶和无机离子等共22项血液生化指标。结果显示，1龄史氏鲟总蛋白（TP）、白蛋白（ALB）和球蛋白（GLB）含量最低，与2～5龄组有显著性差异。5龄史氏鲟GLB最高，且与1～4龄组有显著性差异。1～4龄白蛋白／球蛋白比值（A/G）间无差异，5龄组A/G值显著降低，并与1～4龄组差异显著。随着年龄的增长，胆固醇（CHOL）和高密度脂蛋白胆固醇（HDLC）逐渐升高，与年龄呈正线性相关且相关性显著（P<0.05），5龄HDL-C与1～4龄有显著性差异。所有年龄组中甘油三脂（TRIG）无显著性差异。1～4龄组血糖（G）无显著性差异，5龄组G含量显著降低。尿素氮（BUN）与年龄呈显著负线性相关（〖WTBX〗R=-0.3627），但相关性不显著（P=0.0815>0.05）。CREA与年龄呈正线性相关（R=0.4154, P=0.0389）。1～4龄总胆红素（T-BIL）无显著性差异，5龄最高。1～4龄组碱性磷酸酶（ALP）、谷草转氨酶（AST）、谷丙转氨酶（ALT）无显著性差异，5龄组显著升高，与1～4龄组差异极显著（P<0.01）。所有年龄组的乳酸脱氢酶（LDH）和淀粉酶（AMY）无显著性差异。1龄组钠离子（Na+）最低，并与2～5龄组有显著性差异，2～5龄组中的Na+无显著性差异。各年龄组中钾（K+）、氯（Cl-）、镁（Mg2+）无显著性差异

Haematological biochemical norm of different age groups of cultured Amur sturgeon (Acipenser schrenckii)

Twenty-two items of blood biochemistry of 1-5 year-old groups of cultured Acipenser schrenckii were investigated.The results showed that the values of total protein(TP),albumin(ALB),and globulin(GLB) of 1 year-old group were the lowest,and significantly different from those of 2-5 year-old groups.5 year-old group showed the highest value of GLB, which was significantly different from those of 1-4 year-old groups.There was no significantly difference of the values of ALB/GLB(A/G) among 1-4 year-old groups;however,those values were significantly higher than that of 5 year-old group.The values of cholesterin(CHOL) and high density lipoprotein cholesterin (HDL-C) increased with the increase of age,and indicated positive linear dependence(P<0.05),but the value of HDL-C of 5 year-old group was significantly different from that of 1-4 year-old groups.Among all groups,there was no significant difference of the value of TRIG.There was no significant difference of the value of blood glucose(G) of 1-4 year-old groups,and this value of 5 year-old group was the lowest.BUN and age showed remarkable negative linear dependence(R=-0.3627),but the relativity was not significant(P=0.0815>0.05).CREA and age also showed negative linear dependence(R=0.4154,P=0.0389).There was no significantly difference of the values of alkaline phosphatase(ALP),aspartate aminotransferase(AST) and alanine aminotransferase(ALT) among the groups of 14 year-old,and those values of 5 year-old group were the highest and significantly different from those of 1-4 year-old groups.There was no significant difference of the values of lactate dehydrogenase(LDH) and amylase(AMY) among all groups.Na+ value of 1 year-old group was the lowest and significantly different from that of 2-5 year-old groups;however there was no significant difference of Na+ value among 2-5 year-old groups.Among all groups,there was no significant difference of the values of K+,Cl-and Mg2+.
