Studies on removal of phenol from polluted water by water hyacinths ( eichhornia crassipes)& ⅱ. experiments on the tissue, cell and homogenate level 凤眼莲净化含酚污水的研究&Ⅱ.组织、细胞和匀浆水平的试验
The experiment of mice proved that the flavonoids can enhance the activity of superoxide dismutase ( SOD) in red blood cell and reduce the lipoperoxide ( LPO) level in liver homogenate and had a good anti-oxidation function and enhancing the immune ability. 小鼠实验结果证实,石崖茶类黄酮能显著的提高超氧化物岐化酶(SOD)活力和降低肝匀浆中过氧化脂质(LPO)含量,有明显的体内抗氧化及增强机体免疫功能的作用。
Tumor tissue was frozen twice at-60 ℃ and homogenized by Potter homogenizer. Cell membrane in homogenate was layered and purified by discontinuous Ficoll-gradient centrifugation. 肿瘤组织在&60℃连续冻融两次后,用Potter匀浆器匀浆粉碎,进行Ficoll不连续梯度离心,得纯度较高的细胞膜。
The primary study of bdellovibrio's multiplication by using cell homogenate 蛭弧菌在细胞匀浆中增殖的初步研究
Methods Applying cell homogenate, the crude mitochondrias were prepared. Using MDA colorimetry, the content of MDA, the production of lipid peroxide of the rat liver's mitochondria was determined. 方法采用细胞匀浆丙二醛(MDA)比色法(体外法)测定大鼠肝脏粗线粒体脂质过氧化作用产物MDA的含量。
The results showed that the MDA level in supernate of culture media and cell homogenate increased significantly ( P < 0.01) when the cell was cultured under hypoxic environment, and added various concentrations of tetramethylpyrazine could prevent this phenomenon. 结果显示:血管内皮细胞在缺氧环境中,上清液和细胞匀浆中MDA含量明显增加(P<0.001),加入不同浓度川芎嗪后均可阻止上述现象的发生。
