Abstract
Antioxidant treatment with alpha-tocopherol did not affect the level of the "inflammatory cytokines" in Mg-deficient animals, although it diminished the extent of the myocardial lesions. In another group of Mg-deficient animals chloroquine treatment diminished significantly the levels of circulating cytokines (interleukin-1, interleukin-6, and tumor necrosis factor-alpha) and also resulted in a major decrease in myocardial lesions. These results raise the question of the role of these inflammatory cytokines in the formation of lesions in Mg-deficient myocardium. Because these cytokines are able to stimulate free radical production in various cell types, we postulate that Mg deficiency involves free radical mechanisms that can be amplified by inflammatory cytokines; whether these cytokines initiate lesion formation is unclear. Although our data do not confirm either possibility, we submit that these results implicate a role for the inflammatory cytokines in the cardiac pathology of Mg deficiency.
