Arterial-venous magnesium gradients in hypovolemic shock: an indication of the irreversible state

Arterial-venous magnesium differences were examined in mongrel dogs stressed with reversible and lethal hypovolemia. Increases in serum Mg with hemorrhage have long been known to occur in both humans and animals, yet, increased blood Mg levels have not been viewed as an indicator of the irreversible shock state. The magnesium gradient was shown to be a good indicator of cell destruction which is consistent with lethal shock.

Cardiac tamponade

Cardiac tamponade is an insidious and often fatal complication which can occur on any service, in many diseases, and at any age. The increasing pressure within the pericardium prevents ventricular filling and depresses cardiac output, coronary and systemic perfusion, and venous return. Compensatory mechanisms may protect the patient for some time, but prompt diagnosis and rapid decompression are usually required and must be followed by meticulous evaluation and treatment of the underlying disease.

Mineral element correlation with adenohypophyseal-adrenal cortex function and stress

A statistical correlationl was made between adrenocorticotropin (ACTH) and four elements in rats under control, stress, and stress-recovery conditions. Blood serum zinc showed a strong positive correlation with the rise in ACTH during stress and its decline in stress recovery. Serum calcium, copper, and magnesium demonstrated little correlation with ACTH changes. The strong ACTH-zinc correlation points to an as yet undefined interaction between ACTH and zinc
