摘要
目的探索建立化疗后导致小鼠卵巢功能损伤模型的方法。方法以C57BL/6雌性小鼠为研究对象,以75 mg/kg的剂量一次性腹腔注射环磷酰胺,观察小鼠一般情况、动情周期、血清雌激素(雌二醇)水平以及卵巢组织的形态学改变、各级卵泡数变化、抗苗勒管激素分泌情况和组织纤维化程度。以未注射环磷酰胺小鼠作为对照。结果与对照组比较,环磷酰胺注射小鼠血清雌二醇水平降低,卵巢组织抗苗勒管激素分泌减少,卵巢组织间质增生、纤维化明显,各级卵泡数目减少。结论 75 mg/kg的剂量一次性腹腔注射环磷酰胺后可引起小鼠明显的卵巢功能损伤,小鼠生殖内分泌和卵巢组织学的变化与临床上化疗导致卵巢功能损伤患者的情况相似。该方法简便易行、造模时间短、成功率高、死亡率低,是建立化疗导致卵巢功能损伤动物模型的较好方法。
Objective To establish the mouse model of chemotherapy-induced ovarian failure. MethodsFemale C57BL/6 mice were intraperitoneally injected with cyclophosphamide at the dose of 75 mg/kg.The general conditions,estrous cycles,serum estrogen(estradiol) levels,morphology of ovarian tissues,changes of numbers of follicles,secretion of anti-Mullerian hormone and tissue fibrosis of mice were observed.Mice without cyclophosphamide injection were served as controls. ResultsCompared with controls,the serum estrogen level and secretion of anti-Mullerian hormone of ovarian tissues decreased,there were significant stromal hyperplasia and fibrosis in ovarian tissues,and the number of follicles reduced in mice injected with cyclophosphamide. ConclusionIntraperitoneal injection of 75 mg/kg cyclophosphamide may cause obvious ovarian failure,and the changes in reproductive endocrine and ovarian histopathology are similar to those of chemotherapy-induced ovarian failure in female patients in clinics.It can be used to establish the animal model of chemotherapy-induced ovarian failure due to its simplicity,feasibility,high success rate and low mortality.
