Tykal等提出肌瘤组织与无改变的子宫肌层相比,雌三醇量是增加的。所以寻求一种能降低子宫肌层对雌激素已升高的敏感性,促使甾体性激素代谢正常化因而对子宫肌瘤有治疗作用的药物是十分正确的。Herschberg等在实验和临床观察的基础上提出乙种胡罗卜素有降低雌激素对子宫和乳腺的作用。 Tykal et al. Proposed that the amount of estriol is increased in fibroid tissue compared to the unmodified myometrium. Therefore, to find a can reduce the myometrium has increased the sensitivity of estrogen to promote the normalization of steroid hormone metabolism and therefore have a therapeutic effect on uterine fibroids drugs are very correct. Based on experimental and clinical observations, Herschberg et al. Proposed that beta-carotene may reduce the effect of estrogen on the uterus and breast.
