摘要: 目的 研究维甲酸(retinoic acid RA)诱导建立昆明小鼠腭裂模型的适宜给药时间和剂量.方法 将明确孕期的60只昆明小鼠随机分为4组(A、B、C、D),每组15只.在妊娠(gestation day,GD)10 d时对A、B、C组小鼠分别管饲维甲酸20 mg/kg、50 mg/kg和80 mg/kg,D组管饲玉米油0.20 mL,所有小鼠均任其妊娠足日生产,记录各组孕鼠死亡率、死胎率及活胎鼠中腭裂发生率.采用SPSS 16.0软件包,用x2检验分析各组间差异.结果 B组活胎鼠中腭裂发生率为93.59%,C组活胎鼠中腭裂发生率为20.00%,二者比较差异有统计学意义(P <0.007);C组孕鼠死亡率及死胎率分别为40.00%和76.19%,均明显高于B组,差异有统计学意义(P <0.007);A组与D组中孕鼠未出现死亡,所产胎鼠无死胎亦无腭裂发生.结论 给予GD 10d昆明小鼠管饲50 mg/kg维甲酸是建立腭裂模型的合适方法.

Abstract: Abstract:Objective To study when and how much to dose KM mice while creating the cleft palate model induced by RA ( retinoic acid) . Method Divide randomly sixty KM mice which have been identified in pregnancy into four groups (A,B,C,and D),there were fifteen ones in each group. The mice of group A,B,C were tube-fed RA( retinoic acid) with 20 mg / kg、50 mg / kg and 80 mg / kg respectively at the time of GD10( gestation day 10), while the ones of group D tube-fed with 0. 20 mL corn oil at the same time. All the mice were allowed to reproduce naturally and then record the mortality of pregnant mice,stillbirth rate and incidence of cleft palate in the live fetuses. Data were compared between groups with χ2 test using SPSS16. 0 software package. Result The incidence of live fetuses with cleft palate in group B was 93. 59%,in group C which was 20. 00%,there was significant difference in the two groups (P < 0. 007),but the stillbirth rate and mortality of pregnant mice in group C were 40% and 76. 19%,which were higher than those in group B,the differences were statistically significant ( P < 0. 007) . In addition,the pregnant mice in remaining group A and D were without the occurrence of death and the fetal mice of these groups neither appear stillbirth nor cleft palate deformity. Conclusion Tube-feeding the KM mice with RA 50 mg / kg at GD 10 is an appropriate method of setting up cleft palate model
