Abstract The effects of magnesium on the tension of isolated canine coronary arterial strips were studied. In the solution containing K+ of 20 mEq·l −1, Ca2+ of 4 mEq·l −1, and Na+ of 127 mEq·l −1, the tension was 811 ± 111 mg with Mg2+ of 1 mEq·l −1, 494 ± 135 mg with Mg2+ of 10 mEq·l −1, 272 ± 126 mg with Mg2+ of 20 mEq·l −1, −52 ± 63 mg with Mg2+ of 30 mEq·l −1, −69 ± 80 mg with Mg2+ of 40 mEq·l −1. In the solution containing K+ of 20 mEq·l −1, Na+ of 12 mEq·l −1 and Ca2+ of 0 mEq·l −1, the tension was 102 ± 22 mg with Mg2+ of 1 mEq·l −1, 3 ± 35 mg with Mg2+ of 10 mEq·l −1, −49 ± 33 mg with Mg2+ of 20 mEq·l −1, −59 ± 49 mg with Mg2+ of 30 mEq·l −1, −65 ± 54 mg with Mg2+ of 40 mEq·l −1. The data demonstrated that Mg2+ above 30 mEq·l −1 inhibited the increase in tension caused by Ca2+ and Mg2+ above 20 mEq·l −1 inhibited the increase in tension caused by low Na+ concentration.
