title: [Certain pathogenetic mechanisms of development of atherosclerosis in dogs, induced without the use of cholesterol].
abstract: Chronic investigations (up to 3 years) conducted in dogs have evidenced that periodic disturbances of vascular permeability produced by using dicoumarin with a long-term blocking of the thyroid function greatly aggravate pathological manifestations induced by the action of 6-methylthiouracil. They result in the development in the animals of endogenous hypercholesterinemia, elevated content in the blood of beta-lipoproteins and in a periodic rise of the arterial pressure. These changes were particularly spectacular at the final stage of the experiment in animals with marked manifestations of atherosclerosis and were accompanied by reduced stand-by potentialities of the adrenal gland, disruption of metabolic processes in the myocardium along with the slowed down resorption of NaI131 from the heart muscle. The sensitivity of the heart to adrenalin was down too.
