分生组织的

During embryonic development, many animals form a number of temporary structures along their anterior-posterior axis-somites. Cells in somites differentiate into sclerotome, which gives rise to vertebral column, dermatome, which gives rise to dermis, and myotome, which gives rise to skeletal muscle.

脊椎动物在胚胎发育的过程中沿身体前后轴形成一定数目的暂时性结构－体节，随着胚胎的继续发育每个体节分化成为生骨区、生皮区和生肌区，继而生成各种组织。

Using GSA-〓 lectin histochemistry, the first appearance of microglia occurred at E13, usually stained as scattered amoeboid cells. From then on, the number of microglia increased steadily, reached a peak at postnatal day 7 (P7), and then reduced gradually to adult level. Generally the morphological form of microglia undergoes transformation from early rounded or ameboid to adult resting ramified as they differentiate during development.

使用凝集素GSA-〓亲和组织化学染色，本实验最早观察到小胶质细胞在胚胎13天（E13），为散在分布的圆形或阿米巴样细胞，随后细胞数量逐渐增多；总体而言小胶质细胞的形态遵循着由圆形或阿米巴样逐渐转向纤细分枝状的演变规律，不同阶段细胞形态各有其特点，在不同区域也存在差异；小胶质细胞的数量在生后第七天（P7）达到高峰，其后开始逐步降低直至成年。

And it has been found that in the roots of these vegetables there were aboundant sclerenchymatous cells between the vessels of secondary xylem.

文中对水萝卜、芥菜等根的增粗提出看法，认为不是简单的次生木质部特别发达，而是次生木质部的大型薄壁细胞中散生着成群的小型形成层状细胞，由它们分化成维管组织。

Part 1 Effect of different AAPs at the duodenum on the metabolism and utilization of the amino acids in PDV tissues and in liver and on the concentrations of plasma hormones in IMWC goats In Exp. 1, six wethers of IMWC goats (21-23kg) with the same father, fitted with permanent cannulas at the proximal duodenum, and with femoral artery, mesenteric, portal and hepatic venous catheters were used to study on the metabolism and utilization of the amino acids in PDV tissues and liver of IMWC goats fed diets with different dietary AAPs at the duodenum. In Exp. 2, nine wethers of IMWC goats (21-23kg, 1. 5 years old) with the same father were used to study on the effect of different AAPs at the duodenum on the concentrations of plasma hormones and other biochemical indexes.

试验共分两部分：第一部分：不同氨基酸模式对绒山羊PDV组织、肝脏氨基酸代谢和血液激素水平影响的研究试验1 选用6只体重21～23kg，产绒量约400g，处于生绒旺盛期的1.5周岁内蒙古白绒山羊半同胞羯羊，研究不同小肠可吸收氨基酸模式对绒山羊PDV组织氨基酸代谢的影响；试验2选用9只绒山羊，研究不同小肠可吸收氨基酸模式对绒山羊血液激素等生化指标的影响。
