Characterization of melanin-concentrating hormone in chum salmon pituitaries.
Many lower vertebrates exhibit colour change in response to the background. A dual hormonal control of colour change by two antagonistic pituitary melanophorotropic hormones was first postulated in amphibia by Hogben and Slome. It is well established that the melanotropins alpha- and beta-MSH are responsible for pigment dispersion in the integumentary melanophore of lower vertebrates and that these molecules are derived from a common precursor protein, proopiocortin, by specific processing within the intermediate lobe. No evidence has been found for an antagonistic hormone in amphibia, although the existence of such a molecule in the pituitary gland of teleost fishes has long been recognized and was termed the melanophore-concentrating hormone by Enami. Early attempts to separate the two hormones proved unsuccessful. Recently, Baker and Ball re-invoked the dual hormone concept, and it has been suggested that a melanin-concentrating hormone (MCH) is synthesized in the hypothalamus of teleosts and stored and released by the neurohyphophysis. We have now isolated a novel peptide from the pituitary of the salmon (Oncorhynchus keta) possessing an antagonistic function to MSH, and we describe here its chemical and biological characteristics.

Antidiuretic hormone in acute asthma in children: effects of medication on serum levels and clinical course.
This study of seventeen patients presenting to the emergency room with acute severe asthma determined levels of antidiuretic hormone in serum as well as serum electrolytes and arterial blood gases serially. There was a progressive increase in plasma ADH concentration with severe asthma and ADH levels were substantially higher in those patients with PaCO2's higher than 45 Torr. Patients treated with intravenous aminophylline had a fall in ADH levels while those treated with injectable epinephrine showed an elevation of these levels. As the asthma improved, ADH levels decreased in all patients. In this series of children, sick for not more than 24 hours, serum sodium levels were normal. However, children who have been ill for longer periods than this or who are on prolonged intravenous fluid therapy need close monitoring of serum electrolyte concentrations.
