人工养殖不同年龄史氏鲟的血液生化指标

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

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(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。

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 yea-rold 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 1 - 4 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 Mg^2＋.
