Summary

卵巢切除术和硅胶胶囊和口服花生酱,随后更换17β-雌二醇表明,在大鼠和小鼠。

Abstract

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。

Protocol

1。去势通过背路线麻醉动物,例如1.5%异氟醚诱导的(4%),氧/氧化亚氮混合30%/ 70%。将动物俯卧在直肠温度计连接到一个加热板。重要的是有一层薄薄的动物和板块之间的隔离,温度计反馈系统的体温保持在37±0.5°C。申请保护眼睛凝胶和管理5毫克Rimadyl的/公斤体重生理盐水稀释皮下注射动物的脖子上缓解术后疼痛的侧面。 剃一个4 * 4厘米(3×3厘米)对小鼠面积cephally从髂骨?…

Discussion

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?…
