Results Microscopically, different degrees of hepatocytic degenerative changes and hyperplasic fibrous tissue and typical false lobule formation could be seen. Timm's staining result showed uneven distributed black granular deposits in the hepatocytes. No specific PAS staining was observed. Utrastructurally, the mitochondria were increased in volume and dramatically different in shape. The number of lysomes were increased.

结果 光镜下肝细胞表现为不同程度的退行性变，胶原纤维增生以及典型假小叶形成；Timm's染色阳性，发现不均匀分布黑色颗粒或团块样物质沉积；PAS染色则普遍缺乏特异性染色；超微结构显示线粒体形态多样，体积增大，溶酶体增多，粗面内质网管腔扩张，附着核糖体的脱颗粒，以及胞质水肿，质膜溶解。

While the keratinocytes adhered well on the surface of silicone membrane with pseudopodia formation after 1 week under scanning electron microscope, and the cells kept normal morphological and proliferative properties 2 weeks later.

种植于生物硅膜上的表皮细胞，1周时扫描电镜下见表皮细胞在生物硅膜表面贴附较好，有伪足形成，提示细胞生长良好；2周时光镜下见生物硅膜上的表皮细胞形态仍正常，增殖良好。

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。

As an example, sweet potato is characterized with fleshy tuberous roots for nutrient storage. Factors directing the induction of early tuberization have been investigated for a long time in sweet potato.

块根膨大过程中的营养元素需求、形态变化、内在植物激素消长等方面，长久以来已被广泛研究，但是其基因调控机理至今仍不明确；为此，本研究欲著眼於分子层面来探究甘薯的块根形成机制。

Morphology of the EPCs was observed, and the growth curve of the EPCs was investigated. Surface antigens of the EPCs were analyzed by the flow-cytometer. The capability of intaking the acetylated low-density lipoprotein of the EPCs was detected using fluoresencent chemical method. The vasoformative capability and genetic stability of EPCs were cultured in matrigel, and examined by karyotype analysis.
