| 2. | Critical phases are the embryonic period ( first part of the pregnancy ) and the first 24 hour after birth 母猪繁殖周期中几个关键的时期包括胚胎期(妊娠初期) ,分娩后24小时。 |
| 3. | These are normal term infant kidneys . note the fetal lobulations and the smooth cortical surfaces with some attached adipose tissue 正常足月儿肾脏,可见胚胎期肾小叶;光滑的皮质表面有脂肪组织。 |
| 4. | In the overlap part of the right side of two main faults , the left - lateral strike - slip movement of them in quaternary has formed the embryonic rhombochasm 在两条主要左行走滑断裂的右侧叠覆区,两条主断裂第四纪的左行走滑运动产生一个胚胎期的菱形断陷。 |
| 5. | Stem ce11 factor is a multipotent cytokine which is found in recent years , fol1owing research in vitro and in vivo found that scf and its receptors have familiar regu1ation function in mature brain with in embryo and developing period 干细胞因子是近年来发现的一种多功能细胞因子。近年来研究发现,干细胞因子( stemcellfactor , scf )及其受体对胚胎期及成年后神经系统生长发育起调控作用,但其作用机制尚不明了。 |
| 6. | The digestive tract of animal was not only the important digestive organ but also the biggest endocrine organ which , with a great number of endocrine cells , played an important role in eating , digestion and other physiological activities , and might have regulation effect on the development and differentiation of digestive system of animals 胃肠道不仅是动物体内重要的消化器官,也是动物体内最大的内分泌器官,含有多种内分泌细胞,它们在动物摄食、消化及各种生理活动中具有重要功能,同时可能对胚胎期消化道系统的分化发育起调节作用。 |
| 7. | Marie - therese . loones , sandra m . have investigated the developmental expression of heat shock proteins in the nervous system of the unstressed mouse embryo . the results suggested the biological importance of hsps in neuronal differentiation and migration , as well as in cell signaling , protein transport Marie - therese . loones , sandram . dsouza分别研究了热休克蛋白在小鼠胚胎期和出生后的神经系统发育过程中的分布情况,推测hsps在神经发育过程中可能与神经细胞的分化、迁移以及神经细胞内的信号转导和蛋白质的运输有关。 |
| 8. | In addition , the stomach contained glu - ir cellsn gas - ir cells and vip - ir cells , and the duodenum contained glu - ir cells and gas - ir cells . different endocrine cells varied from one to another in the distribution pattern , the stage of appearance and the number . no glu - ir cell , gas - ir cell or vip - ir cell was found in the oesophagus and no vip - ir cell in the duodenum 另外,胚胎期扬子鳄消化道内分泌细胞的种类和分布与成体有差异,胚胎期消化道检出胰高血糖素、胰多肽和p物质免疫阳性细胞,而成体未检出;胚胎期消化道中胃泌素、血管活性肠肽,生长抑素免疫阳性细胞分布与成体消化道不同。 |
| 9. | The first period is the embryonic period ( from around the usa was found to the middle of the 1960s ) , the second period is the initial period ( from the middle of the 1960s to the end of the 1980s ) , and the third is the flourishing period ( from the end of the 1980s to this day ) 笔者将美国择校制度的发展历程分为三个阶段,即美国择校制度的胚胎期(建国前后至1960年代中期) 、美国择校制度的初步形成期( 1960年代中期至1980年代末期)和美国择校制度的蓬勃发展期( 1980年代末至今) 。 |
| 10. | The ratio of ( s + g2 ) / ( g2 + m + s ) and pi value of mc - 3t3 - el cells increased in the condition of 1um / l e2 . the effects of e2 on igfbp - 6 and igf - 2 gene expressions were suppressed by tcdd and ra . the binding of ere at higfbp - 6 5 " - utr ( dna sequence : aactctgacc , + 94 to + 103 ) was enhanced by tcdd 第三部分igfbp一6基因5 ’一utr中ere的鉴定及功能分析目的:骨骼组织起源于胚胎期中胚层,维持正常的胚胎期骨骼发育需要多种生长因子、细胞因子和激素的参与,其中雌激素可通过多种途径作用子中胚层内间 |
