“…However, the two groups had no difference in regard to cardiopulmonary bypass items, surgical variables, or anesthetic parameters; this indicated that the underlying clinical situations for the study were largely identical in the two groups. Magnesium may 'modulate cellular inflammation' while 'suppressing the inflammatory role of inflammatory cells and cytokines' (34, 35) through the 'activation of N-methyl-d-aspartate (NMDA) receptors', 'phosphoinositide 3-kinase/Akt pathway' and suppression of inflammatory neuromediators through the activation of 'neuro-endocrinological pathways' as the main mechanisms; since, magnesium is a natural antagonist of calcium ion (3-6, 30, 35-37, 42). The inflammatory response after CBP is one of the most significant side effects of this surgical intervention, and a number of compensatory mechanisms and approaches have been proposed, though many remain equivocal (1, 2, 10, 12, 27, 45-49).…”
