It can be associated with overproduction of acute-phase protein in chronic inflammation. Amyloid deposition is rare in rats but is a common age-related change in some mouse strains that presumably have a genetic predisposition. Amyloid in the liver is considered secondary amyloidosis and is seen within sinusoids and blood vessel walls. Histochemical (e.g., Congo red) and immunohistochemical stains are useful for definitive diagnosis. ## 英文原文 · Recommendation Amyloid should be diagnosed and given a severity grade whenever present. ## 配图 - https://www.labsmart.cn/ntp-atlas-images/ntp_0334.jpg - https://www.labsmart.cn/ntp-atlas-images/ntp_0335.jpg 整理:北京天融慧通科技有限责任公司(LabSmart)| https://www.labsmart.cn
