泄殖腔

These two indicated that the ever-decreasing distance between URS and cloacal membrane resulted from change of cloaca configuration.

他们认为尿直肠隔与泄殖腔膜距离的进行性减小是泄殖腔构型变化的结果。

Occurrence of ARM relates to the abnormal cloaca configuration and the failure of fusion of URS with the cloacal membrane.

肛门直肠畸形发生与泄殖腔构型异常以及尿直肠隔未与泄殖腔膜融合等因素有关。

The change of cloaca configuration is related to the differentiation of rectum and bladder; however, it is inappropriate to emphasize this change too much while completely deny the role URS plays.

虽然泄殖腔构型的变化也参与了直肠与膀胱分离的过程，但过份强调泄殖腔构型的变化而完全忽视甚至否定尿直肠隔对泄殖腔的分化作用是不恰当的。

Cloaca configuration changes, URS descends and fuses with eloacal membrane. Through this process, rectum separates from bladder.

泄殖腔构型的变化以及尿直肠隔下降并与泄殖腔膜融合使直肠与膀胱分离。

If the URS does not merge with the cloacal membrane, then the cloaca cannot be differentiated into rectum and bladder.

尿直肠隔是否与泄殖腔膜融合决定泄殖腔是否能够完全分化成直肠和膀胱两部分。

Normal rat embryos and embryos with ARM from gestational days 12.5 to 20 were sectioned serially and sagittally and stained with HE to observe development of cloaca and anorectum continually and contrastively.

胎龄12.5天-20天的正常及泄殖腔发育畸形的胎鼠正中矢状面连续切片，HE染色，连续动态对比观察泄殖腔及肛门直肠的发育过程。

Embryonic development: During normal cloaca development process in rats, before gestational days 15, the urorectal septum developed and clearly demarcated the boundaries of the future rectum dorsally and urogenital sinus ventrally.

结果 ①胚胎发育：泄殖腔发育过程中，胎龄15天前的正常鼠胚，尿直肠隔将泄殖腔分为腹侧的尿生殖窦和背侧的直肠两部分，二者共同相通于泄殖腔管。

Then cloacal membrane is divided into urogenital membrane and anal membrane, until the eighth week, anal membrane ruptures to give rise to anus.

随着胚胎发育，尿直肠隔不断下降与泄殖腔膜的距离越来越小，逐渐与泄殖腔膜融合，同时泄殖腔膜也被分为前后两部分，前者为尿生殖膜，后者为肛膜。第8周时，肛膜破裂，肛门形成。

By dynamic observation of ARM occurrence in ETU treated rats, we found ARM related to the following factors:① Cloacal membrane was too short.② Cloaca configuration was abnormal.③ The tail groove did not form.④ Fusion of URS with cloacal membrane failed.

我们动态观察了ETU诱导的大鼠肛门直肠畸形的发生过程，发现肛门直肠畸形发生与下列因素有关：①泄殖腔膜过短；②泄殖腔构型异常；③没有尾沟形成；④尿直肠隔未与泄殖腔膜融合。

Normal rat embryos and embryos with ARM from gestational days 12.5to 20were sectioned serially and sagittally and stained with HE to observe development of cloaca and anorectum continually and contrastively.

Means the parent directory, so this command means to execute "toolchain.sh," which is in the current directory.

代表父目录，所以这个命令就是执行当前目录下的"toolchain.sh"。

Yes,In fact,I'm on our city ream.

是的。事实上我是我们市队的。
