Accelerated postnatal head growth follows preterm birth 早产儿出生后头围的加速增长
Conclusion Both IGF ⅰ, ⅱ may play an important role in the regulation of catch up growth and the decrease of IGF ⅰ, ⅱ levels may be the internal factors contributing to the absence of postnatal catch up growth in IUGR rats. 结论IGF-、是追赶生长的重要调节因子,其水平的降低可能是IUGR鼠生后缺乏追赶生长的内在原因之一。
Preliminary studies on the reproduction and postnatal growth of Microtus fortis fortis were carried out under laboratory feeding conditions. 在实验室饲养条件下,对东方田鼠指名亚种繁殖特性和幼仔生长发育进行了初步观察。
Reproduction and Postnatal Growth of Microtus fortis fortis under Artificial Feeding Conditions 人工饲养条件下东方田鼠指名亚种繁殖特性及其幼仔的生长发育
14 of the 19 chiropteran families lack data on postnatal growth, and < 3% of known bat species have been investigated regarding their growth and development. Eighty percent of studies on postnatal growth are restricted to the family Vespertilionidae, particularly bats of the temperate zone. 翼手目的19科中有14科缺少出生后生长发育的数据,在已知蝙蝠种类中,对生长发育进行过研究的不超过3%,并且80%的研究局限于蝙蝠科,尤其是温带蝙蝠。
Vascular endothelial progenitor cells ( EPCs) participate not only embryonic vasculogenesis but also postnatal vascular repair, generation and growth of tumour. 血管内皮祖细胞不仅参与胚胎期血管的生成,而且也参与出生后血管的修复、再生及肿瘤的生长等过程。
Study of postnatal growth and Mother-infant communication of bats is one of the major fields in bats study. 因此,对蝙蝠个体发育和母婴交流的研究一直是国内外蝙蝠研究的重点和热点。
IUGR piglet partly realized compensation growth during postnatal 1 week, and the compensation growth increased with age. IUGR仔猪的小肠组织生长在出生后1周内能部分实现补偿,而且补偿生长的实现是随着日龄增加逐步完全的。
Studies on subsequent postnatal growth and on mother-infant communication of bats are important for understanding the aspects of their life history and for understanding a wide range of ecological, behavioral, and developmental patterns. 研究蝙蝠出生后生长和母婴交流行为有利于理解其生活史,同时对其生态学、行为学和发育模式非常重要。
Study on Factors Related to Early Postnatal Ossature Growth of SGA Rat SGA大鼠生后早期骨骼发育相关因素研究
It was shown that CS_2 could result in a significant decrease in the postnatal growth of F_1 rats. 结果表明,CS2可使F1代出生后生长发育明显减慢。
Hence, it is suggested that some of the upper nutrient arteries of the fetus may degenerate and disappear gradually after birth, and the others may change their direction from downward to upward during the period of postnatal growth due to a functional transition. 作者推测胚胎时期的上滋养动脉可能有一部分在生后退化、消失,而另一部分可能在生后发生了方向的转变,由下行而转为上行。

Silver-Russell syndrome ( RSS) is a group of genetically heterogeneous disorders that principally involved intrauterine growth retardation accompanied by postnatal growth deficiency and short stature. Silver-Russell综合征是一组遗传异质性的疾病,主要临床表现为胎儿严重的宫内生长发育迟缓及出生后生长发育迟缓和矮身材。
The patients were selected based on the following criteria: ① MR with two or more of the following conditions: dysmorphic features, prenatal growth retardation, postnatal growth abnormalities, a suggestive family history; 研究对象入选标准:1MR伴以下条件2项或以上:头面部异常特征,手足、生殖器或内脏器官先天异常发现,宫内生长发育迟缓史,生后异常生长发育,阳性家族史;
The hypophyses of postnatal male Wistar rats, first day, 1, 2, 3 weeks, 1 and 3 months after birth, were studied by immunohistochemical staining to ascertain the time of origin, development and differentiation of the growth hormone ( GH) cells. 用免疫组织化学方法对出生后1天,1、2、3周,1及3月的Wistar种大白鼠脑垂体远侧部的促生长激素(GH)细胞的发育分化进行了观察。
