We investigated the effects of the antimycotic agent amphotericin B (AmB) on the phagocytic activity of the isolated perfused rat liver. At a concentration of 5 microM, the drug markedly reduced the clearance of latex beads by the liver as compared to control preparations. Scanning electron microscopy observations showed that latex beads were attached only to Kupffer cells. A liver scan performed infusing 99Tc-colloidal albumin showed that AmB depressed the uptake of the colloid in all hepatic lobes, with no focal defects. Both in control and AmB experiments no trypan blue uptake occurred. The pretreatment of the perfused liver with the calcium antagonist nifedipine prevented the decrease in phagocytosis induced by AmB. In addition, AmB had no effect on livers perfused with a Ca2(+)-free medium. A decrease in the phagocytic capacity of the perfused liver was also observed after the administration of the Ca2(+)-ionophore A23187. The observations suggest that AmB may exert an intrinsic toxicity on the Kupffer cells, which is, at least in part, responsible for the decrease in phagocytosis induced by the drug. This effect may be of relevance to clinical situations and deserves careful consideration.
