EFFECT OF MAGNESIUM DEFICIENCY ON THE REGENERATION OF MAST CELLS AFTER TREATMENT WITH 48/80 IN RATS

Abstract
The decrease in subcutaneous mast cell population observed in rats on a magnesium-deficient diet has been confirmed. Pretreatment with histamine liberator compound 48/80 accentuates the decrease in mast cell counts. This condition was apparently the result of defective regeneration. The decrease in the number of subcutaneous mast cells was accompanied by a parallel reduction of histamine as appreciated by the guinea pig ileum assay. The peripheral vasodilation, which is an early sign of magnesium deficiency, did not appear in rats pretreated with 48/80.
