title: Functional impairment of intact rat liver cells due to biological aldehydes.
abstract: The addition of lipid peroxidation end-products, 4-hydroxynonenal (HNE) or hexanal (HEX) to the incubation medium of rat hepatocytes caused significant decrease of cell cytochrome P-450 content and inactivation of total cell glucose-6-phosphatase. Both the tested aldehydes exerted a marked inhibition of triglyceride secretion by liver cells. The reported results on intact cells furtherly support a possible damaging effect of aldehydes in pathological conditions in which a stimulation of lipid peroxidation occurs.
