本文采用皮下注射外源性OT方法，观察了各种不同剂量的OT对小鼠胚胎早期妊娠的影响。结果显示：各种不同剂量的OT对小鼠胚胎早期妊娠有明显和极明显的抑制作用：对未妊娠小鼠血清中E_2和P含量测定的结果表明：E_2的浓度呈双相反应，OT低浓度时抑制其分泌，高浓度时促进其分泌。各种不同剂理的OT对P的分泌均呈抑制效应。提示OT对小鼠胚胎早期妊娠的抑制作用可能与它破坏了体内内分泌微环境有关。
In this paper, subcutaneous injection of exogenous OT method observed a variety of different doses of OT on the impact of early pregnancy in mouse embryos. The results showed that various doses of OT had obvious and obvious inhibitory effect on the early pregnancy of mouse embryos: The results of the determination of E_2 and P in the serum of non-pregnant mice showed that the concentration of E_2 was biphasic, the OT was low Concentration inhibition of its secretion, promote its secretion at high concentrations. A variety of different OT agents on the secretion of P were inhibited. Tip OT on mouse embryo early pregnancy inhibition may be related to its destruction of the endocrine microenvironment.
