Figure 2. Histopathological alterations involving liver tissues. (A, B) Representative images of HE-stained liver tissues of the NC group; (C, D) Representative images of HE-stained liver tissues of the CIH group. NC group had normal hepatic architecture; CIH group showed some liver cells were slightly edematous with unclear borders. A few hepatocyte nuclei were slightly enlarged. Some cells were in sheets, and the demarcation of the hepatic cord was unclear. All images H&E with original magnification of 200X. NC, normal control; CIH, chronic intermittent hypoxia.
