Core Tip

Core tip: This review systematically appraises the evidence for the key components of the hypothesis of environmental xenobiotic exposure leading to induction of the cytochrome P450 (CYP) system in the pancreatic acinar cell and in turn compromising the free radical quenching pathway in chronic pancreatitis. The central components of the hypothesis of xenobiotic-induced, micronutrient-deficient oxidative-stress mediated cell injury in chronic pancreatitis: xenobiotic exposure causing CYP induction, acinar CYP induction and hepatocyte mediated CYP by-products causing acinar injury by bile reflux do not withstand objective scrutiny.
