The hepatic steatosis was graded according to following criteria, Grade I: increased echogenecity of liver with visible periportal
and diaphragmatic echogenecity; Grade II: increased liver echogenecity with imperceptible periportal
echogenecity without obscuration of diaphragm; Grade III: increased echogenecity of liver with imper-ceptible periportal
echogenecity and obscuration of diaphragm.
The liver acinus: The liver in diabetic rats had more extensive hypertrophy hepatocytes in the periportal
Immunopositivity was more intense in degenerating and remaining hepatocytes, most often encompassing periportal
cord segments and terminal plates (Figure 2, panel D).
Grade I: Increased hepatic echogenicity with visible periportal
and diaphragmatic echogenicity.
One of the stages in the liver failures described is periportal
fibrosis, which was most likely present in our patient (as suggested by the intraoperative findings of the macroscopically altered liver specimen).
D-GaIN caused panlobular focal necrosis and periportal
inflammation, which was accompanied by an inflammatory infiltrate of predominantly polymorph nuclear cells with a few lymphocytes and swollen macrophages (Robert et al.
Heterogeneous appearance of the liver, periportal
involvement, diffuse low signal intensity of spleen on T2-weighted MRI, and thickened bowel wall may be helpful imaging findings when accompanied by presence or history of chronic inflammatory disease and clinical suspicion for amyloidosis.

Histologically, the liver biopsy reveals a chronic necroinflammatory disorder characterized by nonspecific findings such as portal mononuclear cell infiltrate, periportal
lesion (sometimes referred to as piecemeal necrosis or interface hepatitis), bile duct changes, destructive, and non destructive cholangitis and ductopenia present in 25% of patients, plasma cell infiltrate and liver fibrosis.
8 313 Canalicular cholestasis with ductular proliferation, periportal
bridging fibrosis (10m) 3 * 268 1.
The other lesions also observed in these livers were periportal
fibrosis, bile duct hyperplasia, and lymphocyte infiltrates, although with mild intensity.
Histological studies by Prera and Sousa23 indicated hepatic parenchymal vacuolization and periportal
changes after 10 days of 0.
