MELANOCYTE-STIMULATING HORMONE AND PARKINSONISM

The Lancet, 1973
Abstract Circulating b-melanocyte-stimulating-hormone (β-M.S.H.) levels were found to be increased in parkinsonism, especially when the disease was bilateral. This explains the seborrhœa of parkinsonism. The defect in M.S.H. secretion is likely to be part of a widespread neuroendocrine abnormality in parkinsonism.

Behavioral effects of melanocyte stimulating hormone

Neuroscience & Biobehavioral Reviews, 1980
Abstract Consideration of the isolation, structure, localization, and biological actions of melanocyte stimulating hormone are followed by a review of its behavioral effects. Evidence pertaining to various hypotheses offered in explanation of these behavioral effects is examined and evaluated.

α-Melanocyte-stimulating hormone and behavior

Neuroscience & Biobehavioral Reviews, 1982
Melanocyte-stimulating hormone (MSH) has putative adaptive significance in all forms of species where it is present. In mammals the polypeptide chain influences learning, memory and attention. Chemically MSH shares the first 13 (alpha-MSH) or the first 18 or 22 (beta-MSH) amino acids with adrenocorticotropic hormone (ACTH), even though the mechanisms ...

Natriuretic Properties of Melanocyte-Stimulating Hormones

Journal of Cardiovascular Pharmacology, 1993
Proopiomelanocortin (POMC) is a protein that contains the amino acid sequences of numerous peptide hormones, including the melanocyte-stimulating hormones (MSH). MSH peptides of alpha, beta, and gamma primary structure are present in plasma, and all exhibit natriuretic activity.

Melanocyte-Stimulating Hormone and Adrenocorticotrophic Hormone

New England Journal of Medicine, 1964
HYPERPIGMENTATION in patients with adrenocortical insufficiency or some kinds of pituitary tumors is produced by increased release from the pituitary gland of peptide hormones that cause melanocytes to darken.1 2 3 These peptides are the melanocyte-stimulating hormones (alpha and beta MSH) and adrenocorticotrophin (ACTH). The background of this subject

α-Melanocyte-Stimulating Hormone

JAMA, 1991
"Black Skin or White? Science Offers a Choice" was the premature headline for an article written in 1980. 1 Even in 1991, science has not provided individuals with the ability to lighten, darken, or modify the hue of their skin. Tanning by exposure to sunlight or to artificial sources of ultraviolet radiation darkens skin but is considered dangerous ...

α MELANOCYTE STIMULATING HORMONE INDUCES GONADOTROPIN RELEASE

The Journal of Clinical Endocrinology & Metabolism, 1981
The present study demonstrates that synthetic alpha-MSH given as a 2.5 mg intravenous bolus induces an unequivocal rise in LH and FSH in male subjects but not in female subjects during the low estrogen phase of the cycle.

Neuropharmacological tests with α-melanocyte stimulating hormone

Life Sciences, 1976
Abstract The pituitary peptide hormone α-MSH was found to potentiate the behavioral effects of DOPA but not serotonin. It slightly reduced footshock-induced fighting and decreased audiogenic seizures in susceptible mice, but was inactive in reducing the tremors induced by oxotremorine.

Melanocyte Stimulating Hormone

1994
A 13 amino acid peptide (M.Wt. 1665 Da) comprising the N-terminal sequence of ACTH, from which it is derived in the intermediate lobe of the pituitary.

The Melanocyte-Stimulating Hormones

1962
Publisher Summary From a research standpoint the subject of hormonal control of pigmentation is only forty-six years old. It began when two biologists, P. E. Smith and B. M. Allen independently and at the same time, found that removing the pituitary glands of tadpoles and frogs produced marked lightening in the color of their skin.
