摘要:

为了评价FGM发酵黄芪液的安全性，本实验用FGM菌发酵黄芪液及其发酵菌株FGM菌悬液经口灌胃进行小鼠急性毒性试验，试验分为FGM活菌组(FGM)、FGM发酵液组(FAL)、阴性对照组(NG)，分别连续灌胃3 d，每天2次，7 d后处死小鼠，解剖观察。结果显示，试验各组小鼠无中毒反应和死亡。依据小鼠一般体征评价，各组试验小鼠精神状态良好，食欲正常，可判定为Ⅰ级。解剖小鼠后，脏器未发现病变；FGM组、FAL组与阴性对照组相比，小鼠体重，脏器指数、血液指标无显著性差异(P＞0.05)；对主要脏器病理组织切片显微观察，各组小鼠无明显的病理变化。研究表明，FGM菌株及其发酵黄芪液饲喂小鼠，无毒副作用和不良反应。

Abstract:

In order to evaluate the safety of the fermented Astragalus liquid by FGM strain, The mice were divided into 3 groups which include FGM group (FC)，the fermented Astragalus liquid group (FAL) and negative control group (NC), were administrated orally with Astragalus fermentation, FGM stain and normal saline. The mice were sacrificed after 7 days of continuous gavages for anatomical observation. The results showed the mice in all groups didn’t have any toxic reaction and death. According to the standard of general health appearance score of mice, the mental state and appetite of tested mice was normal, and the health level of tested mice was judged asⅠlevel. There were no obvious pathological changes for anatomic observation on mice, and no significant difference in body weight, viscera index and blood index between FAL, FC and NC (P＞0.05). The histological sections of the main organs were observed microscopically without obvious pathological changes. The test showed that the fermented Astragalus liquid and its fermentation strains don’t have no side effects and adverse reactions on mice as feed additive.
