[Electron microscopic mesenchymal response in chronic viral hepatitis].

Background/aims: This study was designed to clarify the fine structures of the hepatocytes and mesenchymal tissues in chronic hepatitis according to severity.

Method: For the purpose of elucidating the ultrastructural characteristics of mesenchymal tissues, liver biopsy specimens were studied by light and electron microscopy in 20 patients with chronic hepatitis.

Results: 1) Hepatocytes in mesenchymal tissues were thought to be in the stage of regenerated or degenerated process.
