形态发生

In comparing the floral morphogenesis with that of other genera with T-type chromosomes in the family, we considered that Coptis contains some primitive characters. The results are consistent with molecular systematic studies showing Coptis as one of the basal groups of Ranunculaceae.

通过与其它具T-型染色体类群在花形态发生上的比较，认为黄连属表现出了某些原始的性状，这一结果与分子系统学研究认为黄连属为毛茛科的基部类群的结论一致。

These uncontaminated explants showed that morphogenetic potential were 70%-75% and each responding explant had 1.2-1.4 shoots formation on MS medium supplemented with 2 mg/L NAA and 16 mg/L BA. Moreover, adding antibiotics (100 mg/L Rifampicin and 100 mg/L Gentamycin) to solidify MS contained 3% galactose were tested, results showed the lowest contamination rates were 20% and 1.0-1.2 shoots were regenerated per responding explant. The antibiotic treatments with 100 mg/L Rifampicin and 100 mg/L Gentamycin could reduce internal contaminants, while the addition of antibiotics into medium in vitro culture led to phototoxic phenomena of axillary explants, morphogenetic potential lost and the growth of regenerant was also inhibited.

以100 mg/L Rifampicin+100 mg/L Gentamycin或100 mg/L Rifampicin+100 mg/L Gentamycin+150 mg/L Streptomycin组合浓度处理者，具有显著降低污染率的效果分别为60%及50%；克服内生菌污染而建立初代无菌培养之腋芽培植体，则以100 mg/L Rifampicin或以100 mg/L Rifampicin+100 mg/L Gentamycin处理者，芽体再生率最高70%-75%，惟平均每一腋芽培植体芽体增殖数仅1.2-1.4个；另在醣种类及浓度与抗生素试验，显示100 mg/L Rifampicin+100 mg/L Gentamycin之抗生素浓度组合添加至含3g/L半乳糖的培养基，显著降低污染率至20%；但未污染之培植体，形态发生潜能低至40%以内，可反应生长之培植体芽体形成数也仅达1-1.2个之间，再生芽体之生长也显现抑制现象。

The results showed that the cells deformed severely, the surface of bacteria became rough and rumply, and the cytomembrane was ruptured after treated by antimicrobial peptide from intestine of grass carp.

结果显示，经过抗菌肽处理后的细菌形态发生变化，菌体严重变形，表面变得粗糙，出现皱褶，胞膜破裂。

Half-ring sulcated external fixator was used for the fixation.

专利号：CN01256565。方法：山羊24只，随机分为单纯异种脱蛋白骨组、自体骨组及异种脱蛋白骨＋重组人骨形态发生蛋白组，在每只山羊右侧胫骨中下段截除胫骨总长度20%形成节段性骨缺损，按分组情况植入不同材料，采用半环槽式外固定器固定。

Result Compared with the control group,the femur BMD and biomechanical properties in the model group markedly decreased (P＜0.05);the tissue microstructure of the proximal tibiae showed obvious pathological changes of osteoporosis.

结果 模型组与正常组比较，股骨骨密度降低(P＜0.05)，胫骨上段骨组织形态发生典型骨质疏松改变，股骨生物力学性能降低(P＜0.05)。

ABSTRACT: Objective In order to investigate the treatment of bone defect repairing by recombinant adenovirus transudation the hBMP7 gene, the vector of hPMP7 recombinant Ad was constructed.

目的 为了研究人骨形态发生蛋白7(hBMP7)导入骨缺损模型中的治疗作用，构建重组腺病毒载体。

This paper was mainly working on the biochemical changes (water, carbohydrate, lipid, fatty acid, protein, amino acid) during embryonic development of Cherax quadricarinatus. At the same time, we especially worked on the yolk protein-vitellin in two aspects: 1. Isolation, purification and characterization of vitellin from the ovary of female Cherax quadricarinatus.

本文对红螯螯虾胚胎发育过程中的主要生化物质(水分、碳水化合物、脂类、脂肪酸、蛋白质、氨基酸)进行了测定，特别是对胚胎发育过程中主要的营养物质——卵黄磷蛋白的结构和含量变化做了细致的研究，同时讨论了这些物质的变化与红螯螯虾胚胎发育形态发生的相关性。

In the early stage of its development, once induced by the morphogen,transcription factors such as SHH, WNT and BMP, are specifically expressed in neuronalcells to trigger the downstream effects, and determine the cell fate finally.

在神经系统发育的早期，在SHH，WNT，BMP等形态发生因子的调控下，神经细胞内的转录因子特异性表达，并启动一系列的转录事件，最终决定神经细胞分化方向。
