Catecholamine (CA)
A catecholamine (abbreviated CA) is a monoamine neurotransmitter, an organic compound that has a catechol (benzene with two hydroxyl side groups next to each other) and a side-chain amine. Fitzgerald, P. A. (2011). “Chapter
Sound-induced convulsions in the hamster associated with magnesium deficiency (1947)
Exposure of 16 hamsters maintained on an Mg deficient diet, 10 animals placed on a control diet immediately after a first convulsive attack, 10 Mg-deficient animals given Mg supplements after each induced convulsion, and 12 control animals maintained on adequate purified diet, to sound tests, indica
Magnesium Deficiency Causes a Reversible, Metabolic, Diastolic Cardiomyopathy (2021)
Background Dietary Mg intake is associated with a decreased risk of developing heart failure, whereas low circulating Mg level is associated with increased cardiovascular mortality. We investigated whether Mg deficiency alone could cause cardiomyopathy. Methods and Results C57BL/6J mice were fed wit
The hyperventilation syndrome: a neurosis or a manifestation of magnesium imbalance? (1985)
It has been proven with clinical, psychological and electromyographic tests that the hyperventilation (HV) syndrome cannot be separated from so-called genuine tetany. Tetanic patients with and without HV are characterized by a significant hypocalcemia; but a significant hypomagnesemia is exclusively
Latent tetany and anxiety, marginal magnesium deficit, and normocalcemia (1975)
The identification of marginal magnesium deficit, such as we have detected in a patient with anxiety, depression, and psychomatic complaints, is a difficult diagnostic problem. Electromyography of a limb, rendered acutely ischemic either just before or after hyperventilation, can elicit latent tetan
Hypomagnesemic tetany of ruminants (1988)
Hypomagnesemic tetany of ruminants is a noninfectious metabolic disorder that occurs in a wide range of nutritional and management conditions. This article considers its etiology and pathogenesis, clinical signs, clinical pathology and lesions, diagnosis, clinical management, prevention, and control
The magnesium-deficiency tetany syndrome in man (1960)
Magnesium is second only to potassium in abundance as an intracellular cation. The whole body of a human adult contains nearly 25 gm. The numerous important biochemical reactions dependent upon the presence of this metal have been discussed elsewhere. Magnesium is an essential nutrient for animals
Studies on the nutritional basis of abnormal behavior in albino rats; the effect of pyridoxine deficiency upon sound-induced magnesium tetany (1945)
After a magnesium deficient diet for 5 to 8 days, young rats showed vasodilatation, hyperirritability, and latent tetany. Brief exposures to the sound of a resonated buzzer elicited severe tonic-clonic convulsions. When such a diet was continued for 10 to 23 days, sensitivity increased with death re
