上面介绍的管理模式，在早先的研究证明优于商业缓释微丸生产生理血清浓度17β-雌二醇注射。而缓释微丸生产非常高，长期的血药浓度峰值，注射导致极端情况下，每天的激素的波动，需要反复的动物4-6压力处理。选择适当的管理模式的重要性，强调了最近的研究表明，虽然低剂量的17β-雌二醇的管理方案（如在目前的文章中提出的技术）防止脑缺血8-10，17β-雌二醇浓度由生产?...

雌激素是女性性激素的影响格外广泛的家庭。当大鼠和小鼠使用雌激素的研究，它们通常以消融迅速骑车激素生产，更换外源性17β-雌二醇去势。有，然而，缺乏有关激素应如何管理，以获取生理血清浓度的共识。这是至关重要的，因为17β-雌二醇的水平/管理方法深刻地影响实验结果1-3。我们有一系列特点17β-雌二醇管理的不同模式的研究，发现皮下硅胶胶囊和每口螺母，奶油花生酱均优于市售缓释微丸（创新研究由美国公司生产）在生产生理血清浓度的17β-雌二醇4-6每日注射。当中高级坚果冰淇淋的方法，以前一直使用丁丙诺啡管理7，antages是，当雌激素的管理使用，它类似于口服激素替代疗法和非侵入性。皮下硅胶胶囊是方便和生产最稳定的血药浓度。这部影片的文章包含了卵巢切除术的一步一步的示范和17β-雌二醇激素替代硅橡胶胶囊和口服花生酱在大鼠和小鼠，其次是行政程序的重要方面进行讨论。
