Résumé
Because of its unique advantages , zebrafish has been more and more widely used in drug screening and safety assessment , environmental protection , developmental biology and other fields . But the standardization of environments, feed, and water environment of zebrafish are prominent problems and weakness which hindered their application .This paper probes into the standardization of environment and feed of zebrafish in Zhejiang , in order to promote its standardization construction .
Résumé
A method for determinations of germanium in garlic was developed by means of acid digestion and extraction under reflux. It obriated not only the volatile loss of Ge but also the loss of volatile Allicin in the Allium sativum, with usual distillation methods. At the same time the sensitivity was remarkably increased under coprecipitation with ferric hydroxide and extraction operation. A good linear relation was obtained in the range of 0-2.0?g Ge. The average recovery of Ge is 90.9%, coefficient of variation is 4.0%, and detection limit in the Allium sativum is 0.14?g. The method is suitable for determination of Ge in other biological samples as well.
