摘要: 目的 测定长爪沙鼠糖尿病模型近交系培育群体的遗传生化位点标记和生物学特性的基础数据。方法 采用Beckman全自动生化分析仪(CX5)和日本光电全自动血细胞分析仪(MEK-7222K)对17项血液生化和22项血液生理指标进行测定;醋酸纤维板电泳法检测26个生化位点标记;选择F20代种鼠,按照近交系动物生产方式进行繁育,统计分析胎间隔、初生数、离乳数,生长曲线等。结果 血液生理和生化指标之间比较ALP、HDL-C、CRE指标差异极显著(P<0.01);MCV、MCH、EOS、GLU、TG、LDH指标差异显著(P<0.05);遗传生化位点标记呈现单一性;初生体质量为2.68~3.38 g,离乳成活率为68.31%,胎间隔时间比较长。3~6周龄体质量增长较快。结论 研究结果为其品系鉴定和生物医学应用提供重要参考资料。

Abstract: Objective The basic data of genetic biochemical markers and biological characteristics of the breeding population of the inbred strain of Mongolian gerbil diabetes model. Method Using Beckman automatic biochemical analyzer (CX5) and Japan photoelectric automatic blood cell analyzer (MEK-7222 K) of 17 blood biochemical and 22 blood physiological indexes were determined; detection method of electrophoresis acetate fiber 26 biochemical marker; F20 rat, inbred animal production in accordance with the way of breeding, analysis of fetal the interval, number, weaning number statistics, growth curve. Result The result of the blood physiological and biochemical comparison between ALP, HDL-C and CRE index were significant differences (P<0.01); the difference of MCV, MCH, EOS, GLU, TG, LDH were significantly (P<0.05); a single genetic biochemical marker; birth weight is 2.68—3.38 g, the survival rate of weaning 68.31%, fetal long time. The quality of the 3—6 week old body weight increased rapidly. Conclusion The result of the study provide important reference materials for the identification of their lines and the application of biomedical applications.
