W。 A。 Rocca博士和同伴在1月15日的《神经病学》杂志上写道，很多动物研究表明雌激素在黑质纹状体通路的神经保护作用与降低帕金森病的风险有关联，但是来自临床和流行病学研究的证据还没得出结论。

Animal researchers milk mother seals as part of their study.

动物研究牛奶的母亲海豹的一部分，他们的研究。

BPH is a common disease in old people, it often causes bladder outlet obstruction and destrusor instability. It is reported that the morbidity, rate of detrusor instability secondary to BPH is from 52% to 80%. There are many hypotheses concerning detrusor instability, The study of detrusor denervational hypersensitivity and changes of detrusor ultra-structure are intensively popular at present. But most of the research work were only limited in animals. In order to gain the insight into its mechanism, we Carried out a series of studies on detrusor instability secondary to BPH obstruction in men.

BPH是老年人常见疾病，常导致膀胱出口梗阻和逼尿肌不稳定，有报道BPH梗阻性逼尿肌不稳定的发生率为52-80％，引起逼尿肌不稳定原因很多，其中逼尿肌去神经超敏和超微结构的变化是目前研究的热点，但大多限于动物实验，鉴于此，我们对BPH梗阻性逼尿肌不稳定进行了初步的研究，拟探讨其发生机制。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.
