摘要: 摘要:目的 测定不同周龄MIJ、HFJ近交系大鼠血液生化指标,观察其特征表现,为进一步研究提供基础参考数据。方法 取4、8、12周龄不同性别(含MIJ雄性不育大鼠)MIJ、HFJ大鼠,每组20只,测定其谷丙转氨酶(ALT)、谷草转氨酶(AST)、碱性磷酸酶(ALP)、总蛋白(TP)、血清白蛋白(ALB)、血清球蛋白(GLO)、谷酰转肽酶(GGT)、肌酐(CRE)、血清尿素氮(BUN)、血糖(GLU)、尿酸(UA)、甘油三酯(TG)、总胆固醇(TC)、高密度脂蛋白胆固醇(HDLC)、低密度脂蛋白胆固醇(LDLC)指标,计算得出AST/ALT,A/G。结果 HFJ、MIJ两个近交系雌性大鼠比较:碱性磷酸酶(ALP)、低密度脂蛋白胆固醇(LDLC)指标在4、8、12周龄三个组均差异极显著(P<0.01);HFJ雄大鼠与MIJ雄性正常大鼠比较:低密度脂蛋白胆固醇(LDLC)指标在4、8、12周龄三个组均差异极显著(P<0.01);HFJ雄大鼠与MIJ雄不育大鼠比较:血糖(GLU)指标在4、8、12周龄三个组均差异极显著(P<0.01),低密度脂蛋白胆固醇(LDLC)指标仅在12周龄差异极显著(P<0.01);HFJ近交系雌雄大鼠比较:HFJ雄性大鼠的ALP指标测定值在三个时间点始终高于HFJ雌性大鼠且差异有显著性(P<0.01)。结论 MIJ、HFJ大鼠血液生化指标因动物品种品系、年龄、性别等不同而有不同的表现。MIJ雄性不育大鼠的血液生化指标未表现明显缺陷。这些血液生化指标数据对其进一步研究及应用等具有重要参考意义。

Abstract: Abstract: Objective The purpose of this study was to determine blood biochemical parameters of HFJ and MIJ rats in different weeks, observe their characteristics of performance, and provide a basic reference data for further research in MIJ and HFJ rats. Method Blood samples were collected from 4, 8, 12 weeks MIJ and HFJ rats (including MIJ male sterility rats) of different gender, 20 in each group. The biochemical parameters were determined including glutamic-pyruvic transaminase (ALT), aspartate aminotransferase (AST), alkaline phosphate (ALP), total protein (TP), serum albumin (ALB), serum globulin (GLO), glutamyl transferase (GGT), cretonnes (CRE), serum urea nitrogen (BUN), blood sugar (GLU), uric acid (UA), triglyceride (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDLC) and low density lipoprotein cholesterol (LDLC). Calculated the AST/ALT, A/G. Result Comparison of biochemical parameters in female rats of HFJ and MIJ showed: alkaline phosphate (ALP) low-density lipoprotein cholesterol (LDLC) indicators at 4,8,12 weeks of the three groups were extremely significant difference(P<0.01); HFJ male rats and MIJ males were compared in normal rats: low density lipoprotein cholesterol (LDLC) indexes were significantly different in the three groups of 4, 8 and 12 weeks (P<0.01). HFJ male rats compared with MIJ male infertility in rats: blood glucose (GLU) indicators at 4, 8, 12 weeks of three groups were extremely significant difference (P<0.01), low density lipoprotein cholesterol (LDLC) index in just 12 weeks of age difference was significant (P<0.01); The ALP index of HFJ male rats was consistently higher than HFJ female rats at three time points and the difference was significant (P<0.01). Conclusion Blood biochemical parameters of MIJ and HFJ rats were different because of the difference of species and strains of animals, age and gender. Blood biochemical parameters of MIJ male sterility rats did not show obvious defects. These blood biochemical parameters data have important reference significance for the further research and application in MIJ and HFJ rants.
