Core Tip
Core tip: We investigated the role of the nitric oxide (NO) pathway in the pathogenesis of acute hepatic failure (AHF). The precise pathomechanism of AHF is poorly understood. In our study, most liver function parameters improved both before and after the induction of liver damage following inhibition of the NO pathway. Prophylactic administration of the inhibitor was more effective in improving liver function parameters. On the other hand, stimulation of the NO pathway after liver damage, regardless of the donor dose used, also improved most liver function parameters. Therefore, the NO pathway significantly influences the development of experimental galactosamine-induced AHF.
