The mouse model of hepatic veno-occlusive disease.

With the application of hematopoietic stem cell transplantation, Subacute or acute increase in the incidence of hepatic veno-occlusive disease (HVOD) becomes more common and it can lead to fatal complications. This article characterizes a mouse model of HVOD induced by monocrotaline. After gavage with monocrotaline was performed on BALB/c mice, On the 3rd, 4th, 6th, 8th and 10th days, mice were anesthetized, blood was collected and the liver was removed. Liver slices were processed by HE stain, Masson's trichrome stain or immunohistochemical stain. From days 3 through 4, histopathology and cytokine changes were determined as severe, early HVOD. From days 6 through 8, the changes were considered to represent late HVOD. On the 10th day, the above changes showed that late HVOD gradually improved.
