On day 18 of pregnancy, conceptuses were surgically removed in order that rabbits would be left with seven, five, three, or one conceptus. During pregnancy, blood concentrations of relaxin were determined by radioimmunoassay. There was no difference between relaxin concentrations in rabbits carrying one versus seven conceptuses. The results indicate that conceptus number does not influence the blood concentration of relaxin in the rabbit.
在妊娠第18天，通过手术取出胚胎，以使兔子分别保留7个、5个、3个或1个胚胎。在整个孕期，采用放射免疫分析法测定松弛素的血药浓度。携带1个胚胎的兔子与携带7个胚胎的兔子的松弛素浓度没有差异。结果表明，胚胎数量不影响兔子体内松弛素的血药浓度。
