    Description / Table of Contents: Zusammenfassung Bei alten Schweinen einer großen Zuchtherde wurden mehr oder weniger fortgeschrittene atherosklerotische Veränderungen an Aorta, Herzkranz-, Gehirn-und anderen Arterien festgestellt. Zehn Mutterschweine im Alter von 12–14 Jahren aus dieser Zuchtherde wurden in Einzelbuchten abgesondert. Fünf Tiere wurden mit den üblichen Küchenabfällen gefüttert. Die anderen fünf erhielten zur Abfallnahrung zusätzlich Trockeneigelb in einer Menge von mindestens 35% der gesamten Kalorienaufnahme. Nach einer Versuchsdauer von 12 bis 14 Monaten war die Atherosklerose an Aorta und extramuralen Herzkranzarterien bei den mit Eigelb gefütterten Schweinen bedeutend weniger fortgeschritten als bei den Kontrolltieren. Die Veränderungen an den intramuralen Koronar- und an den Gehirnarterien erschienen bei beiden Gruppen ungefähr gleich. Es wird vorgeschlagen, daß frühere Experimente, nach welchen Eigelbverfütterung Atherosklerose bei wachsenden Schweinen stark beschleunigt, nach anderen Faktoren, die möglicherweise zu diesen Ergebnissen beitrugen, neu überprüft werden.
    Notes: Summary Ten older female swine (12–14 years) from the breeding herd that had been a consistent source of animals with more or less advanced atherosclerosis of aortas, extramural coronary, cerebral arteries and other sites were separated to individual pens. Five were continued on the customary garbage ration, and the remainder fed the garbage ration, supplemented by dried egg-yolk in amounts that would supply at least 35 persent of caloric intake. Egg-yolk feeding for 10 to 14 months was associated with significantly less aortic and extramural coronary atherosclerosis. Intramural coronary and cerebral atherosclerosis was not measurably different in the two groups. We suggest that earlier experiments that have found the progress of atherosclerosis in growing animals to be accelerated by egg-yolk feeding should be reexamined for other factors that could have contributed to this result.

    Description / Table of Contents: Zusammenfassung Bei 223 Herzen adulter Menschen wurden stenosierende atherosklerotische Veränderungen an extra- und intramuralen Arterien quantitativ ausgewertet. Zwischen beiden Arteriensystemen besteht eine positive Korrelation hinsichtlich Grad der stenosierenden Atherosklerose. Einzelne Herzen mit nur geringgradiger Stenose extramuraler Arterien wiesen jedoch eine hochgradige Stenose intramuraler Arterien und gleichzeitig Mikroinfarkte auf. Solche Befunde können Symptome einer ischämischen Herzkrankheit beim Fehlen nachweisbarer extramuraler Coronarstenosen erklären. Stenosierende Veränderungen an extraund intramuralen Coronararterien haben eine gemeinsame Pathogenese und entwickeln sich durch Reorientierung, Proliferation und Migration von pleomorphen glatten Muskelzellen der Arterienwand, kombiniert mit vermehrter Bildung von Mucopolysacchariden, elastischen und kollagenen Fasern. Diese Genese entspricht derjenigen der stenosierenden Coronarsklerose beim Schwein und anderen Species.
    Notes: Summary Atherosclerotic stenosis of the extramural coronary arteries was quantitated for a series of 223 hearts of adults and found to correlate positively with values for stenosis of the intramural coronary arteries of that series. However, minor grades of extramural coronary stenosis may be associated with advanced stenosis of the intramural coronary arteries and myocardial microinfarction, which may explain symptoms of ischemic heart disease in the absence of demonstrable extramural coronary stenosis. Stenosing lesions of extramural and intramural coronary arteries apparently involve the same process, and develop through reorientation, proliferation and migration of pleomorphic smooth muscle cells of the arterial wall, combined with increased formation of mucopolysaccharides, and elastic and collagen fibers. The process corresponds to that by which coronary arterial stenosis appears to develop in swine and other animals.

    Notes: The hepatic lobules of the family Suidae are unusually large, completely surrounded by fibrous tissue, and supplied by relatively large branches of the hepatic artery. The interlobular septa carry small branches of the artery, vein and bile ducts of the adjacent portal tracts and may be regarded as attenuated extensions of the portal tracts. The hepatic lobules of Tayassuidae and Hippopotamidae lack these distinctive features.
