摘要: 通过黄曲霉毒素B1(aflatoxin B1,AFB1)诱导大鼠肝细胞凋亡的定量数据,从而构建AFB1诱导大鼠肝细胞凋亡率的剂量效应模型。通过拟合模型获取决定系数和进一步的数学检验表明,Gamma模型(R2=0.996 4,赤池信息量准则=37.40,贝叶斯信息准则=17.19)优于其他模型。建议选用Gamma模型作为大鼠急性暴露于AFB1后肝细胞凋亡率的最优剂量效应模型,用于AFB1风险评估框架中的危害特征描述。

Abstract: This study aimed to construct a dose-response model of aflatoxin B1 (AFB1)-induced apoptosis rate in rat hepatocytes by using quantitative data. The coefficients of determination (R2) and further mathematical tests showed that the Gamma model (R2 = 0.996 4, Akaike information criterion = 37.40, and Bayesian information criterion = 17.19) was superior to other models. Hence, the Gamma model was recommended as the optimal dose-response model for apoptosis rate in rat hepatocytes after acute exposure to AFB1 for hazard characterization in the framework of AFB1 risk assessment.

Key words: aflatoxin B1; hepatocyte apoptosis; risk assessment; dose-response model
