While occasional mitoses can be seen in a normal liver, finding more than one or two mitoses per 10 high-power fields is not typical for adult rodents. In this example, the high frequency of mitosis ( Figure 1 , arrows) is a repair response following hepatocyte loss secondary to treatment with a hepatotoxicant. ## 英文原文 · Recommendation An increased frequency of mitosis is unusual; it should be documented whenever present and given a qualitative severity grade. ## 配图 - https://www.labsmart.cn/ntp-atlas-images/ntp_0354.jpg 整理:北京天融慧通科技有限责任公司(LabSmart)| https://www.labsmart.cn
