Plasma ACTH and melanocyte-stimulating hormone in nail pigmentation.
occur with some anticancer agents such as cyclophosphamide (Shah et al., 1975), 5-FU and nitrogen mustard (Moore and Meiselbaugh, 1975), and also with exposure to x-rays (Sutton, 1952; Inalshingh, 1972). Priestman and James (1975) reported 3 cases in which nail changes were possibly due to doxorubicin. They speculated that this drug has a selective hormone-suppressive action which might allow a...
متن کاملRole of the kidney in regulating plasma immunoreactive beta-melanocyte-stimulating hormone.
An analysis of the factors that influence the increase in plasma immunoreactive beta-melanocyte-stimulating hormone (beta-MSH) concentration in chronic renal failure showed that: (a) the increase correlated with the increase in serum creatinine concentrations; (b) beta-MSH was not cleared from the plasma by haemodialysis; (c) beta-MSH concentrations increased with length of time on dialysis and...
متن کاملMelanocyte stimulating hormone and melanin concentration hormone may be structurally and evolutionarily related.
Two melanotropic peptides, melanin concentration hormone (MCH) and alpha-melanocyte stimulating hormone (alpha-MSH), exert opposing actions on melanosome (melanin granule) movements within teleost pigment cells, melanocytes (melanophores). MCH stimulates melanosome aggregation to the cell center whereas alpha-MSH stimulates pigment organelle dispersion out into the dendritic processes of the me...
متن کاملY2-Melanocyte-Stimulating Hormone
Peptides of the pro-opiocortin class produce pronounced cardiovascular and natriuretic actions. We have investigated the acute cardiovascular effects of one of the most potent members of this class, y2-melanocyte stimulating hormone (y2-MSH), in rats. Pressor actions of y2MSH administered systemicaMy were eliminated by ganglionic blockade with chlorisondamine. Peripheral cholinergic blockade fa...
متن کاملMelanin concentrating hormone (MCH): structure-function aspects of its melanocyte stimulating hormone-like (MSH-like) activity.
Melanin concentrating hormone (MCH) is a heptadecapeptide, Asp-Thr-Met-Arg-Cys-Met-Val-Gly-Arg-Val-Tyr-Arg-Pro-Cys-Trp-Glu-Val, synthesized in the brain and secreted from the pars nervosa of teleost fish. This hormone stimulates melanosome (melanin granule) aggregation within integumental melanocytes of fishes but, in contrast, stimulates melanosome dispersion within tetrapod (frog and lizard) ...
