  • Title: High-fat diet enhances the accumulation of hexachlorobenzene (HCB) by pregnant rats during continuous exposure to HCB.
    Author: Nakashima Y, Ikegami S.
    Journal: J Agric Food Chem; 2003 Mar 12; 51(6):1628-33. PubMed ID: 12617596.
    Abstract:
    To investigate the influence of a high-fat diet on HCB distribution and accumulation, pregnant rats in study 1 were fed a high-fat or control diet containing HCB, and, in study 2, pregnant rats were given a single HCB dose by intragastric gavage and HCB-free high-fat or control diet. In study 1, the high-fat diet group had higher HCB concentrations in fat tissues and liver than did the controls. In study 2, although the total amounts of HCB in the fat tissue and liver were greater in the high-fat diet group than in the controls, no significant differences in HCB concentration were observed between the two groups. The high-fat diet group also showed more fecal excretion of HCB. Therefore, HCB accumulation in rats fed a high-fat diet was enhanced more by continuous exposure to HCB than by administration of a single dose.
