Aortic Rupture, Body Weight, and Blood Pressure in the Turkey as Influenced by Strain, Dietary Fat, Beta-aminopropionitrile Fumarate, and Diethylstilbestrol

“…DES depressed blood pressure, in confirmation of previous findings of Krista et al (1965) and Simpson and Harms (1965). Other treatments had no effect on blood pressure.…”

“…High energy rations have been implicated as a contributing factor. The advent of these diets and the presence of atherosclerotic plaques at the rupture sites (Carnaghan, 1955;Gibson and de Gruchy, 1955) raise the question of the role of blood lipids in the etiology of this malady, but Krista et al (1965) found that added dietary animal fat and cholesterol did not alter the incidence of aortic rupture.…”

“…Subcutaneous implantation of DES increases the incidence of aortic rupture (Krista et al, 1965;Simpson and Harms, 1965) with a concomitant rise in blood lipids (Simpson et al, 1964). Ball (1964) and Kurtz (1966) noted an increase in lipid deposition at plaque sites and Kurtz (1969) observed plaques with ulcerations in birds receiving DES.…”

Characterization of Rupture of Abdominal Artery Aneurysm in Dairy Cattle

“…In pigs and turkeys, defects in lysyl oxidase secondary to copper deficiency result in decreased and abnormal layering of elastin, resulting in subsequent arterial rupture. 3,4,11 The elastin within the vessels in cattle with Marfan syndrome is similarly abnormal, resulting in vascular rupture. 8 In humans with abdominal artery rupture, direct damage to the vessel wall or damage secondary to deposition of antigen-antibody complexes can result in fragmentation and break down of elastin.…”

Influence of Diethylstilbestrol on the Turkey With Special Reference to Histological Changes in the Aorta

“…DES implantations have been reported by Krista et al (1961Krista et al ( , 1965, Beall et al (1963), and to increase the incidence of aortic rupture in turkeys. Krista et al (1965) and reported a concomitant decrease in blood pressure with an increase in aortic rupture.…”
