We detected that EGF mRNA was expressed sflungly lii the oocyte, and is also found hi gmnulosa cells, the cell fium smaller foflicular expressed stronger than fium bigger one. In the corpus hemonbaglcwn corpus luteurn, lean type and pseudocorpus-luteum, EGF rnRNA was detected,, no distinct difference can be seen in them. The EGF mRNA expressed strongly in fimbria end, ampulla and isthmus of oviduct, in the big follicular stage, ovulation stage, pregnancy stage and spurius pregnancy stage, we can not see any distinct change in them, but hi the medium follicuar stage,it is weaker.

结果发现：猪卵母细胞中EGF的mRNA强烈表达，且小卵泡卵母细胞→中卵泡卵母细胞→大卵泡卵母细胞中，EGF的mRNA表达量有逐渐减少的趋势；猪卵泡的颗粒细胞中有EGF的mRNA表达，小卵泡颗粒细胞→中卵泡颗粒细胞→大卵泡颗粒细胞中，EGF的mRNA表达也有逐渐减少的趋势；猪卵巢中的红体、黄体、白体和假黄体中都有EGF的mRNA表达，看不出几部分的表达量有明显的强弱变化；猪输卵管伞部、壶腹部和峡部，都有EGF的mRNA表达，在大卵泡期，排卵期，孕期和假孕期都强烈表达，各期间看不出明显的强弱变化，中卵泡期表达较弱；猪子宫中EGF的mRNA在大卵泡期，排卵期，孕期和假孕期都强烈表达，看不出表达量的明显变化，而小卵泡期表达量明显减弱。

There is only 1 case report of a pars interarticularis defect in an infant who also had other spinal abnormalities; thus, isthmic spondylolisthesis does not seem to be a congenital disorder.

只有一例峡部不连的婴儿患者的报道，而且该患者同时有其他的脊柱畸形。因此峡性脊椎前移似乎不是一种先天性的障碍。

He quoted Schultz's study in which he examined 400 primate skeletons without finding any cases of spondylolisthesis, as evidence that bipedal posture is a factor that contributes to this condition.3 The idea that repetitive stress increases an individual's risk of isthmic spondylolisthesis is also supported by studies that show an increased risk of pars defects in athletes who participate in sports involving hyperextension, such as gymnastics,4 diving, wrestling, and weight-lifting.5

他引用了Schultz的研究，他检查了400个灵长类的骨骼，没有一例脊椎前移，这个发现成了双足站立姿势是导致这种疾病的因素的证据。3运动员，尤其是从事需要过伸腰部的运动，如体操4、跳水、摔跤和举重5的运动员发生峡部不连的风险增加，这也支持了反复应力增加了发生峡性脊椎前移风险的观点。

Mechanical loading of cadaveric vertebrae in a manner which mimics forces on an upright spine has been shown to cause pars interarticularis fractures.14 Bipedal posture in combination with additive stress on the lumbar spine due to repetitive flexion and extension appears to have a major role in the development of isthmic spondylolisthesis.

在尸体椎体上模拟对垂直脊柱的机械负荷可以造成峡部的骨折。14双足站立姿势加上反复屈伸对腰椎产生的应力，这似乎是造成峡性脊椎前移最主要的原因。

The results indicate that the reproductive organs of adu-lt female Wanxi White Geese consisted of the ovarium and tuba uterina,Left ovariumand tuba uterina developed normally,but the right one had degenerated.There werefive parts in tuba uterina:the infundibulum part,albumen secreting part,isthmus pa-rt,utera part,a...

结果表明成年皖西白鹅母鹅的生殖器官包括卵巢和输卵管两部分，仅左侧发育正常，右侧早已退化，卵巢大小随鹅的年龄和季节有很大变化；输卵管分为漏斗部、蛋白分泌部、峡部、子宫部和阴道部五个部分。

The aim of this study was to investigate the expression of mPGES-2 protein in mouse oviduct during the early pregnancy, pseudopregnancy, and estrous cycle by immunohistochemistry and Western blot. The regulation of mPGES-2 protein in mouse oviducts was also studied under delayed implantation, steroid hormonal treatments and oviductal ligation.

本实验主要利用早期妊娠、假孕、输卵管结扎、发情周期、激素调节以及延迟着床等实验模型，结合免疫组织化学和Western blot 的实验方法，详细研究了mPGES-2 蛋白在小鼠输卵管中的表达与调节。mPGES-2 蛋白主要定位于不同时期的伞部和壶腹部的上皮纤毛细胞中，在伞部和壶腹部肌层以及峡部和宫管连接处的上皮和肌层中未检测到mPGES-2 蛋白的表达。

Clinically occult carcinoma ranging in size from 1 to 13mm was initially detected in 11 of 102 women (5 in tubal fimbriae only, 1 in tubal isthmus only, 2 in fimbriae and ovary, and 3 in ovary only).

首次诊断发现102例中有11例隐藏着1至13mm大小的隐匿性癌（5例只位于输卵管伞部，1例只位于输卵管峡部，2例位于输卵管伞部和卵巢，另3例只位于卵巢）。

Failure to seal the isthmus will lead to eventual failure. The recognition and treatment of the canal isthmus may be one factor that will reduce the failure rate of surgical endodontics.

在根尖手术中，根尖切除后使得原本与外界不通连的峡部暴露，对于峡部预备及充填的不足往往会导致手术的失败。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
