Effect of dietary magnesium on Ascaris suum infections of mice.
Low amounts of dietary magnesium affected the inflammatory tissue response in nonimmunized mice differently than in immunized mice. Eosinophil numbers and LPL activity in lung tissue following infection with A. suum larvae were altered by the level of magnesium in the diets of mice. Average or higher dietary levels of magnesium resulted in decreased numbers of lung larvae indicating an overall protective effect. Increases in eosinophil numbers or LPL activity were not directly related to the numbers of larvae/lungs. Larvae/livers, eosinophil numbers, and LPL activity were affected by the types of magnesium diets that mice received. Nonimmunized mice had differences in larvae/liver (at 2 days and 7 days pi) and LPL activity (at 2 days pi). Immunized mice had varying findings at 2 days pi but a direct relationship between dietary magnesium and numbers of larvae, numbers of eosinophils, and liver LPL activity at 7 days pi.
