Part Two: The effect of fruit extract on CRL-2606 production of PGE2 Effect of anthocyanin rich fruit extracts on endothelial cells'PGE2 production Epidemical experiment shows that phenolics in fruits and vegetables may prevent the occurrence of chronicle cardiovascular heart disease. To investigate the activity of fruit extracts on artery blood vessel cells, we chose CRL-2606 cell line, a normal iliac artery endothelia cells. Using indomethacin as control, we investigate the effect of blueberry extracts, blackcurrant extracts, chokeberry extracts, cyanidin3-glucoside, and malvidin3-glucoside on the PGE2 production of CRL-2606 cells.

第二部分水果提取物对人体细胞系CRL-2606产生PGE2的影响水果提取物对血管内皮细胞释放PGE2的影响流行病学调查表明，蔬菜水果中的多酚类物质具有预防慢性心血管疾病的作用，为研究水果提取物对血管细胞的作用，我们选择回肠动脉内皮细胞CRL-2606细胞系作为研究对象，以indomethacin为对照，研究了blueberry，blackcurrant，chokeberry提取物及cyanidin3-glucoside，和malvidin3-glucoside对血管内皮细胞释放PGE2的影响。

METHODS Retinal cells were cultured in commixture and retinal ganglion cells in pu-rification,to observe the state of ganglion cells and its axon.RESULTS Retinal ganglion cells that cultured in commix-ture grew very well.

The ultrastructural changes during the development of sieve element companion cell complex (SE/CC complex) in Populus deltoides were investigated using electronic microscopy. The result showed that SE and CC tome from the same secondary phloem mother cell. The development of sieve element went through three stages, i. e. immature, mature, and degenerate stage. In immature stages the sieve element presented radial expansion, cell wall thickening, and production of sieve plastid and P-protein. The cytoplasma selectivly autolysed in mature stage. At the same time, karyoplasm was dispersed, and nuclear envelope was not clear, or karyoplasm was disorgnized, and nuclear envelope was clear. The karyopalsm finally turned into P-protein. In degenerate stage, the cytoplasm completely disappeared, and the function was lost.

利用电镜技术研究美洲黑杨次生韧皮部筛管和伴胞发育过程中细胞超微结构的动态变化，观察到筛管和伴胞由同一个次生韧皮部衍生细胞分裂分化形成筛管约发育历经未成熟期、成熟期和衰退期的变化未成熟期筛管分子表现为细胞的径向扩展、壁的增厚、筛管质体和P-蛋白质的产生；成熟期筛管分子细胞组分发生选择性自溶，细胞核核质弥散状，核膜不清晰，或核膜清晰而核物质降解，最后细胞核完全解体转化为P-蛋白质类的物质；衰退期筛管分子细胞质完全解体消失，失去功能。

The students read texts to obtain the microscope-related concepts which included the following: making water mount specimen to be observed by depending on the correct steps, the image of object shown on compound microscope was enlarged directly by the specimen; some differences of structure were found both plant cell and animal's cell, animal's cell does not have cell walls and chloroplasts, it unable to photosynthesis; small living beings of water, consumers, will eat little small living beings.

学生由阅读文章而获得的细胞相关概念主要有：能依正确的步骤，制作一个水埋法标本片进行观察，在复式显微镜下观察到的影像和实物是左右相反、上下颠倒的，植物细胞和动物细胞的形态及构造有些差异，动物细胞不具细胞壁、叶绿体，无法行光合作用，有些水中的微小生物会摄食更小的微小生物，是消费者。
