Purpose: Histochemical and immunohistochemical changes were observed in hepatocytes to study the developing and recovery processes of halothane-induced hepatic injury from 0 to 7 days after halothane exposure.

Methods: A total of 330 7-week-old male Sprague-Dawley rats, with or without phenobarbital preteatment, were exposed to halothane in 100%, 21%, 10% oxygen or oxygen alone for 2 h.

Results: In the phenobarbital group, degenerated hepatocytes were observed immediately after exposure to 10% oxygen, both with and without halothane: glycogen and ribosomal ribonucleic acid (rRNA) disappeared immediately and 6 h after exposure, respectively, and necrosis developed in zones 3 to 2 at 6 h after exposure.

Differential, histochemical and immunohistochemical changes were observed in hepatocytes from immediately to 7 days after isoflurane or sevoflurane exposure (at H 0 to on Day 7) to study the process of development and recovery in anesthetic-induced hepatic injury. A total of 570 7-week-old male Sprague-Dawley rats with or without phenobarbital treatment were exposed to isoflurane or sevoflurane in 100%, 21%, or 10% oxygen, or to 10% oxygen alone for 2h. In phenobarbital-treated rats, hepatocytes both with and without anesthetic exposure markedly changed in 10% oxygen at H 0.
