The selected calluses exhibited higher I50 and higher relative amount of growth in the presence of ethionine. 该愈伤组织在含乙硫氨酸的培养基上表现出较高的半抑制剂量和相对生长量。
The membrane surface was damaged.CONCLUSION: Ethionine and tetracycline can lead to the hepat... 结论:乙硫氨酸和四环素均可不同程度地导致肝细胞的脂肪变性。
Methods:Feeding mice on ethionine and high fat diet induced the model of fatty liver, the contents of TC and TG were measured after pestling the hepatic tissue into pulp. 方法:采用乙硫氨酸及高脂饲料造成脂肪肝模型。取肝组织匀浆,测其TC、TG。
These results suggest that the presence of ethionine might have caused the alteration of more than one enzyme in the biosynthesis of amino acids in the selected calluses. 说明在所筛选愈伤组织中存在一个以上与氨基酸合成相关的酶发生改变。
METHOD: The hepatocyte was cultured in vitro and given two damage factors,ethionine and tetracycline and then observed by the scanning electron microscope. 方法:体外培养肝细胞,给予2种药物损伤因子(乙硫氨酸和四环素),以扫描电镜观察为指标,考察模型组的变化。
A Selenium-enriched yeast strain L-11-7-2 was obtained from Saccharomyces cerevisiae L-11 as starting strains by DES mutagenesis and screening on plate containing Na2SeO3 and ethionine. 以酿酒酵母Saccharomyces cerevisiaeL-11为出发菌株;通过DES多次诱变;Na2SeO3和乙硫氨酸抗性平板选择;得到一株高硒和高蛋氨酸含量的菌株L-11-7-2;其蛋氨酸含量达到1.;37%25;是L-11的169%25。
