Antinociceptive action of hemopressin in experimental hyperalgesia.

abstract：:Ghrelin is a peptide that has protective effects on many tissues of the body. It has anti-inflammatory and anti-oxidant effects. Acetaminophen, a commonly used analgesic-antipyretic drug, has hepatotoxic side effects. The aim of this study was to evaluate the protective role of ghrelin in liver toxicity due to acetami...
