By imitating different concentration of Cd2+ Cu2+ Cr3+ Cr6+and Zn2+polluted water environment,we mainly studied their toxic effects on aquatic piants by means of measurement of physiologicai indexes and electron microscopy observation as well as the relieving to Cu2+ injury of antioxidase enzyme system in Lemna minor L. and Vallisneria asiatica Miki in this paper by throwing Ce.the experimental results showed that Cd2+ Cu2+ Cr3+ Cr6+ and Zn2+ might injure photosynthetic systems, protective enzyme system, substance metabolism systems and cell ultrastructure of the plant.

本文通过模拟不同浓度梯度的重金属Cd~(2+)、Cu~(2+)、Cr~(3+)、Cr~(6+)和Zn~(2+)污染环境，利用生理生化测定、扫描电镜、透射电镜、气相色谱及激光共聚焦等实验手段，研究了四种金属离子对不同生态型的水生植物的毒害影响，初步探索了Ce对浮萍Cu害的缓解效应和La、Zn及其交互作用对浮萍活性氧清除系统影响。

Bamboo first crystallizes then lignifies during bamboo shoot growth and basically forms crystal structure in one month. 1-year-old bamboo culm ends growth and its height,thickness, volume almost change little, but culm tissue is small and tender and there is more water and less substance in it. Bamboo crystal proportion keeps invariable during this period.2-year-old bamboo culm begin to lignify,its cellulose proportion debases and its crystal proportion decreases. Bamboo lignin debases, crystal proportion changes a little in the end of this period.Many-old-year bamboo culm crystal proportion is almost invariable. Freaky bamboo cell wall crystal region's thickness is less than normal bamboo's. Bamboo cross section crystal area and the ratio of long axis to short axis are less than normal bamboo's,and roundness,irregular index, the fiber cap density per unit area increase more than normal bamboo's.

竹笋生长阶段是先结晶后木素化的过程，一个月内细胞壁结晶组织基本形成；2）一年生竹材的植株秆茎生长结束，秆茎的高度、粗度和体积变化不大，但秆茎的组织幼嫩，含水量高，干物质少，竹材结晶度基本不变；3）二年生竹材的植株开始木质化，纤维素比例降低，结晶度减少，到后期竹子木质化降低，竹材结晶度变化不大；4）多年生竹材的结晶度没有太大的变化，结晶度大小处于波动状态；5）畸形竹材纤维帽细胞壁结晶区的厚度比正常竹小，其横截面结晶区的面积、纤维帽长轴与短轴比有所减少，而圆形度、异型指数有所加大，单位面积纤维帽的密度增大。

Recombinant human Mullerian inhibiting substance suppresses the growth of MISIIR-positive ovarian cancer cells by inducing apoptosis and cell cycle arrest. We predict that rhMIS might be a new target to treat human ovarian malignancies.

重组人苗勒抑制物可以抑制MISIIR蛋白表达的卵巢癌细胞增殖、诱导其凋亡、阻滞细胞周期，这有望成为治疗卵巢癌的一个新靶点。

2Myocardial ultrastructure was normal in the control group,myoneme arranged disordered,the structure of typical sarcomere disappeared, mitochondrium intumesced,interstitial substance fiber hyperplasy,capillary vessel endothelial cell swelled in DG group.Myocardial ultrastructure improved slightly in rats of SM and LM groups. 3NF-κB p65 and COX-2 had a small quantity to present in the myocardium tissue of control group,while the quantity increased obviously in the diabetic group.The level of it in the group of treatment was significant lower than that in the diabetic group.There was significant difference between the two groups. Conclusion Metformin can protect against the heart injury in diabetic.

结果 1与对照组比较，DG组体重明显减轻，血糖、心脏质量指数、INS、TG、T-CH及FFA明显升高(P＜0.01)；应用 MT治疗后体重无明显增加，INS有所下降，心脏质量指数、血糖、TG及FFA明显降低(P＜0.01)；DG组心肌组织MDA明显升高，SOD明显降低(P＜0.01)，MT治疗后上述指标明显改善；2超微结构观察单纯糖尿病组肌丝结构明显紊乱，典型肌小节结构消失，线粒体肿胀、间质纤维增生，微血管内皮细胞肿胀等表现，而SM及LM组可见组织结构有所改善；3对照组心肌NF-κB p65及COX-2只有少量表达，单纯糖尿病组表达量明显增多(P＜0.01)，MT治疗后表达量明显减少(P＜0.01)。

It is mainly used for adjuvant treatment of high blood pressure; the most common use of rutaceae is treatment of allergies, which can slow down the speed that the mast cell releases histamine, while histamine is right the chemical substance causing general allergic reaction.

主要用於高血压辅助治疗；芸香素的最常见用途是治疗过敏，它可减缓肥大细胞释放组织胺的速度，而组织胺正是引起一般过敏反应的化学物质。

according to the mechanism of bitter formation, the bitter taste masking technology is classified into different sorts from different taches that disturb the bitterness formation, include adding the taste correcting substance to confuse the cerebral taste; staving or preventing the drug releasing in mouth and segregating the contact between drug and taste buds; anesthetizing the taste cell to enhance the threshold of bitter taking; preventing bitter taste receptor combining with bitter blocker, cutting off the signal transduction pathways etc.summerize the methods of taste masking technology,besides,describe the method's advantages and disadvantages, and the technology of preparation.provide academic direction for the reasonable use of bitterness taste masking.

依据苦味形成机理，从干扰苦味形成的不同环节将中药苦味掩味技术分为添加矫味剂，混淆大脑味觉掩盖药物苦味；延缓或阻止药物在口腔释放，隔离药物和味蕾的接触；麻痹味觉细胞，提高苦味感受阈值；阻止苦味受体与苦味剂的结合，切断信号传导掩盖苦味等4类，综述掩盖中药苦味的方法，并简述各方法的优缺点和制备技术，为合理应用苦味掩味技术提供理论指导。
