异常发育

Five fetuses were diagnosed with female pseudohermaphroditism (21-hydroxylase deficiency in 3 and urorectal septum malformation sequence in 2). Four fetuses were diagnosed with male pseudohermaphroditism (1 with steroid sulfatase deficiency, 1 with presumed camptomelic dysplasia, and 2 undetermined).

在这16个胎儿中有5个被诊断为女性假两性畸形（其中3个有21-羟化酶分泌不足，2个有尿道直肠隔畸形），4个被诊断为男性假两性畸形（其中1个有类固醇硫酸酯酶分泌不足，1个推测可能为弯肢性发育异常，另外2个原因未定），5个有染色体异常，2个有性逆转，核型为（46，XX+SRY）。

The aberrant epigenetic reprogramme is an important cause for abnormal development of nuclear transfer embryos.

表观重编程异常是核移植胚胎发育异常的重要原因。

Arterial compliance may be affected by the retarded uterus growth through lowering the accumulation of elastin scleroprotein in the aorta wall, and the reduced arterial compliance perhaps causes adult's hypertension in the babies with low birth weight.

Martyn认为，可能的机制是，在宫内发育阶段，营养不良等因素影响了动脉壁弹力蛋白的发育异常，降低了动脉顺应性降低，从而导致了低出生体重儿童进入成年期后容易发生高血压。

Result: in three categories and ten examples of congenital malformation fetus, the morphological and histological structures of colon in syndactyly and sxtrodactyly fetus have no obvious abnormity; the colon's structure shows abnormity in omphalo-thoracopagus twins; the colon's structure was insufficient development in anencephaly fetus.

结果：三类10例先天性畸形胎儿中，并缺指畸形胎儿结肠的形态学及组织学结构无明显异常；胸腹联体胎儿结肠结构异常；无脑儿结肠组织结构发育不全。

Microcephaly, occipital meningocele, dysplastic ears, optic atrophy, vertebral abnormalities, limb problems including radiohumeral synostosis, subluxation of one hip, joint contractures, and focal femoral hypoplasia.

小头畸形，枕部脑脊髓膜膨出，耳发育不良，视神经萎缩，脊椎异常，四肢问题包括：桡肱骨结合、一侧髋关节脱位、关节挛缩和灶性股骨发育不良。

It is deduced that the abnormal development of tapetum and the abnormal distribution of Ca(superscript 2+) are related to the pollen abortion.

推测绒毡层细胞结构发育的异常和Ca(上标 2+)的异常分布可能与花粉的败育有关。

The results showed that the cell wall organization during anther development failed to divide into inner-wall, middle and tapetum normally, and not to provide material, energy and information transfer for the development of pollen mother cells, resulting in the occurrence of abnormal pollen mother cells separatist period; thus which could not form a normal pollen grains which led to abortion.

结果表明，不育花药壁组织在发育过程中，没有分化形成正常的内壁、中层及绒毡层，不能为花粉母细胞的发育提供物质、能量和信息的传递，造成花粉母细胞在减数分裂期发生异常，不能形成正常的四分体，因而未能形成正常的花粉粒而导致败育。

These results suggest that ethanol be the major factor in dysfunction of brain development whereas acetaldehyde plays critical roles in other organ teratogenesis.

上述结果提示FAS中的脑发育异常是乙醇独立作用的结果，乙醛则引起FAS中的辅助畸形。关键词醇，乙乙醛胚胎发育胎儿酒精综合征联合作用

Chromosomal abnormalities were identified in two anencephalic fetuses. One was trisomy 21, another was mosaic of diploid and tetraploid.

1。组织病理学和超微病理发现，NTDs胎儿在脑和脊髓以及重要脏器如肝、肾等发育有异常，主要表现在发育滞后和某些成分的缺如。

The development of Peiai 64S and IR36 did not differ up to microsporocyte formation stage; but since meiosis stage, male reproductive cells of Peiai 64S underwent several structural changes and ultimately terminated by early bicellular stage.

结果表明，小孢子母细胞减数分裂之前，培矮64S与IR36的发育过程基本相似。但从减数分裂开始，培矮64S的雄性性细胞出现一些异常变化，并最终发育至二胞花粉早期败育。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
