    Notes: Summary A new polypeptide hormone candidate regulating vascular smooth muscle function was extracted from porcine atrial tissue. The purification steps were followed by a bioassay. The hormonally active substance has been analyzed and found to be a small polypeptide exhibiting a molecular weight of about 7500 and is named “cardiodilatin” (CDD). Further chemical data on this new hormone will be published elsewhere. A partial amino acid sequence of cardiodilatin is offered and shows that among the well known hormones or neuropeptides, none exhibit a homologue partial sequence.

    Description / Table of Contents: Résumé L'utilisation systématique de recuits, contrôlés par des examens radiocristallographiques à températures variables, a permis de faire disparaître les équilibres métastables qui se manifestent entre les hydroxydes de lithium et de sodium. Trois composés sont identifiés avec certitude: 2 LiOH · NaOH, LiOH · NaOH et LiOH · 2 NaOH. Le composé équimolaire est dimorphe, la variété haute température étant de symétrie cubique.
    Abstract: Zusammenfassung Die systematische Anwendung von Prozessen der Wärmebehandlung, welche durch radiokristallographische Untersuchungen bei verschiedenen Temperaturen kontrolliert wurde, ermöglicht den Abbruch der zwischen dem Lithium- und Natriumhydroxid bestehenden metastabilen Gleichgewichte. Drei Verbindungen konnten mit Sicherheit charakterisiert werden: 2 LiOH · NaOH, LiOH · NaOH und LiOH · 2 NaOH. Die äquimolare Verbindung ist dimorph, wobei die bei höherer Temperatur stabile Art eine kubische Symmetrie besitzt.
    Notes: Abstract The systematic use of annealing operations controlled by radiocrystallographic examinations at various temperatures permits the elimination of metastable equilibria which occur between lithium and sodium hydroxydes. Three compounds have been characterized with certainty 2 LiOH · NaOH, LiOH · NaOH and LiOH · 2 NaOH. The equimolar compound presents in two crystalline forms: the high-temperature variety crystallizes in the cubic system.

    The auricular myocardiocytes of the heart constitute an endocrine organ characterization of a porcine cardiac peptide hormone, cardiodilatin-126 (1984)

    Notes: Summary A peptide hormone was extracted from the porcine right atrium following a bioassay for differential vaso-relaxant effects on smooth muscle strips from aorta and renal and inferior mesenteric arteries. The isolation procedure included several steps of gel-permeation and ion-exchange chromatography, and high performance liquid chromatography. During the isolation procedure, other peptides of smaller molecular weight were also found, which, in relation to cardiodilatin-126 (CDD-126), are shorter at their N-terminal. Among these, CDD-88 has also been isolated and characterizied, and has been established as a prominent member of the cardiac hormone family. The N-terminal and C-terminal segments of the 126 amino acid-containing molecule were synthesized and used to raise region-specific antibodies. The natural peptide was then localized within myoendocrine cells of the right atrium where specific atrial granules are located. Renal effects of cardiodilation were studied in conscious dogs and showed strong diuretic and natriuretic activities. According to our functional studies, cardiodilatin-126 and cardiodilatin-88 possess qualities of a significant hormone family regarding the regulation of extracellular fluid volume and blood pressure.
