microsomes 中文意思是什麼

microsomes 解釋
（微粒體）：與核糖體結合的碎片狀內質網。

  1. Preliminary data indicate that steviol may be activated to a mutagenic metabloite by human liver microsomes

    初步數據顯示，甜菊醇可能經人體的肝臟微粒體活化成引致基因突變的代謝物。
  2. While some data suggest that epoxidation may be involved in the metabolic activation of steviol, other data indicate that the active metabolite is not an epoxide. preliminary data indicate that steviol may be activated to a mutagenic metabloite by human liver microsomes

    有些數據指出，甜菊醇在代謝活化的過程中，可能牽涉環氧化作用，但其他數據顯示，甜菊醇的活性代謝物並不是環氧化物。
  3. Now transgenic cell lines that express the protein encoded by ugt gene were broadly used instead of liver microsomes. the enzyme expressed in cell lines helps to realize the function of a specific gene and will provide direct information related to the isozyme interested

    『為解決上述問題，國際上人們己經廣泛採用建立各種ugt轉基因細胞系的方式試驗，在明確基因構成的倩況下直接獲得由特定基因所表達的ugt同工酶， fi什對性地研究該酶對藥物的代謝作用。
  4. Knowledge of distribution and regulation of ugts remains limited. liver microsomes is a frequently used enzyme source in in vitro study of glucuronidation, but it has the following deficient respects : 1. liver microsome is a mixture of various enzymes, and therefore the results from microsome cannot represent the function of a individual isozyme

    關于ugts的組織分佈和調節這方面的知識還不多，過去常採用肝微粒體進行研究，但有以下缺陷： u ）肝微粒體是多種藥酶沮合的復雜體系，因而實驗結果難以區分是一種同工醇的作用
  5. Ip3 - ip3 receptor ( ip3r ) interaction mediates the release of ca2 + from the endoplasmic reticulum in response to many different extracellular stimulus. for higher plants, however, though it is now generally accepted that ip3 participates in signal transduction in many important cellular processes, only limited evidence is available for the presence and properties of the ip3r - like protein so far. here, using the immunological methods with an antibody raised against a mammalian inositol 1, 4, 5 - triphophate receptor ( type 1 ), we found that, 1 ) the antibody across - reacted the proteins with about 200kd in microsomes from oryza sativa and about 200kd from arabidopsis thaliana respectively

    本實驗用sds - page電泳和免疫印跡的方法，用哺乳動物大鼠三磷酸肌醇受體的多肽做抗體對類三磷酸肌醇受體蛋白鑒定，結果表明：抗體與水稻和擬南芥微粒體蛋白分子量大約為200kd的蛋白交叉反應，同時還發現在水稻微粒體蛋白62kd和擬南芥微粒體蛋白45kd處有交叉反應的蛋白條帶存在，表明在植物中有類三磷酸肌醇受體蛋白的存在；用免疫膠體金方法，發現類三磷酸肌醇受體蛋白主要分佈於液泡膜和細胞質膜上。
  6. Additionally, protein bands were found in the range of 62 kd in microsomes from oryza sativa and 45 kd from arabidopsis thaliana -, 2 ) the ipar - like protein was mainly localized in the vacuolar membrane ( tonoplast ) and plasma membrane in the leaf and root tip of arabidopsis thaliana for confirming the biological role of the ip3r - like protein, we investigated the effects of methyl viologen ( stimulating ip3 produce ) and heparin ( a competitive inhibitor of inositol 1, 4, 5 - triphophate in animal ) on stomatal movement by epidermal strip bioassay. when the epidermal strips of arabidopsis thaliana were treated with methyl viologen, it stimulates the stomatal closure

    擬南芥表皮條用甲基紫精處理，可以引起氣孔的關閉，當處理90分鐘的時候，氣孔的相對開度由100降到58 ，統計學分析氣孔開度的變化有顯著差異；甲基紫精引起氣孔關閉的作用可以被肝素部分抑制，當甲基紫精和肝素同時處理90分鐘的時候，氣孔的相對開度由100降到92 ，統計學分析氣孔開度的變化沒有顯著差異，說明氣孔的相對開度基本上沒有變化。
