Comparison of serum biochemistry between specific pathogen-free and coventional aged Wistar rats

目的 探讨普通级、SPF级老龄Wistar大鼠血清生化值的差异。方法 用Coulter-JT全自动生化检测仪检测血清生化值。结果 在老年SPF级Wistar大鼠的雌性与雄性之间,谷丙酶、总蛋白、碱性磷酸酶、总胆固醇、甘油三酯、尿素氮、肌酐、铁、磷、血糖、尿酸、低密度脂蛋白差异非常显著(P<0.01),白蛋白、乳酸脱氢酶、载脂蛋白B差异显著(P<0.05)。老年SPF级雄性Wistar大鼠与老年普通级雄性Wistar大鼠间的总蛋白、白蛋白、白球比、总胆固醇、甘油三酯、血糖、载脂蛋白Al、载脂蛋白B、尿酸、高密度脂蛋白、低密度脂蛋白、谷草酶差异非常显著(P<0.01),谷丙酶、铁、镁差异显著(P<0.05)。老年SPF级雌性Wistar大鼠与普通级雌性Wistar大鼠间的谷丙酶、总蛋白、白蛋白、白球比、碱性磷酸酶、甘油三酯、尿素氮、肌酐、铁、载脂蛋白Al、载脂蛋白B、高密度脂蛋白、低密度脂蛋白、胆汁酸差异非常显著(P<0.01),镁含量差异显著(P<0.05)。结论 微生物学等级因素对Wistar大鼠的血清生化值有影响。

Objective To investigate the differences in serum biochemistry between specific pathogen-flee (SPF) and conventional aged Wistar rats. Methods Coulter-JT Analyzer was used to measure the values of serum biochemistry in the two grades of rats. Results The serum levels of alanine aminotransferase (ALT), total protein (TP), alkaline phosphatase (ALP), total cholesterol (TC), triglyceride (TG), blood urea nitrogen (BUN), creatinine, Fe, P, glucose, uric acid (UA), and low density lipoprotein (LDL) were very significantly different between male and female Wistar rats of either conventional or SPF grade (P<0.01), which also had significant difference in albumin, lactate dehydrogenase (LDH) and apolipoprotein B (ApoB) (P<0.05). Between male aged Wistar rats of the two grades, the differences of TP, albumin, albumin/globulin (A/G) ratio, TC, TG, blood glucose, ApoA1, ApoB, UA, high-density lipoprotein (HDL), LDL, and glutamic oxalacetic transaminase (GOT) were very significant (P<0.01), with also significant differences in ALT, Fe, Mg (P<0.05). Between the female rats of the two grades, the serum levels of ALT, TP, albumin, A/G ratio, ALP, TG, BUN, creatinine, Fe, ApoA1, APOB, HDL, LDL, and bile acids were very significantly different (P<0.01), and Mg was significantly different (P<0.05). Conclusion Different microbiological profiles affect serum biochemistry of aged Wistar rats.
