Besides depressing the patient's immune system, it may generate many parallel undesirable effects like blocking the production of the natural hormone of adrenal cortex, or steroid called cortisol, which may be the cause of a malfunctioning of the adrenal gland, causing hypofunction or hyperfunction of the gland.

Later in contemplation of an immune response, Burnet added, "The failure of antibody production against autologous cells demands the postulation of an active ability of the reticulo-endothelial cells to recognize 'self' patterns from 'non-self' patterns in organic material taken into their substance" ( 3 ).

In this way, cortisol and catecholamines work synergistically to promote the breakdown of muscle glycogen into glucose for use in the muscle tissue. (wikipedia.org)

The Salimetrics cortisol assay kit has also been formatted to minimize cross reactivity for related steroids. (salimetrics.com)
