We investigated the in vivo effects of 1,25-dihydroxyvitamin D3, and serum calcium and inorganic phosphorus concentrations on productions of leukotriene B4 and 5-hydroxyeicosatetraenoic acid by glycogen stimulated peritoneal neutrophils of the rat. Neutrophils were incubated with ionophore A23187 for 5 min and the incubation medium was subjected to a reverse-phase high performance liquid chromatography for quantitation. Productions of these lipoxygenase metabolites by neutrophils from vitamin D depleted rats were decreased compared to the vitamin D sufficient levels. This difference was not observed when arachidonic acid was added to the incubation medium. When serum calcium concentrations of rats were altered by dietary calcium levels but 1,25-dihydroxyvitamin D3 was administered to those rats, the difference in serum calcium concentration did not show any effect on the production of leukotriene B4. In contrast, neutrophils from 1,25-dihydroxyvitamin D3 sufficient but phosphorus deficient rats still demonstrated decreased leukotriene B4 production. This reduction was corrected by exogenous arachidonic acid. The data suggest that 1,25-dihydroxyvitamin D3 or cellular calcium translocation mediated by the hormone, and serum inorganic phosphorus independent of 1,25-dihydroxyvitamin D3 affect arachidonic acid release, thus productions of leukotriene B4 and 5-hydroxyeicosatetraenoic acid.
