Oxygen consumption of the thoracic aorta of normal and hypercholesteremic rats.

چکیده
ACCORDING to Christie and Dahl 1 the abdominal portion of the rat aorta shows a significantly lower respiration than its thoracic segment. The divergence increases with, aging. Briggs, Chernick and Chaikoff,in an earlier study, did not detect this phenomenon. The first authors suggest that the preferential sites of development of atherosclerotic lesions might show a lower rate of respiration. This suggestion prompted a study of the oxygen uptake of aortic tissue under conditions favorable for the development of atheromatosis.

متن کاملDissimilarity in Oxygen Consumption between the Thoracic and Abdominal Aorta in Rats
Measurement of oxygen uptake by thoracic and abdominal segments of rat aorta showed significantly lower rates in the abdominal than in the thoracic aorta of adult animals. The evidence suggests that as a rat ages the respiratory rate of abdominal aorta falls more sharply than that of the thoracic segment. This result may provide an explanation for the relatively high incidence of atherosclerosi...

The purpose of this study was to determine if any changes occurred in the basal and stimulated rates of oxygen consumption and lactate production of thoracic aortas from spontaneously hypertensive rats (SHR) and renal and deoxycorticosterone acetate (DOCA)-salt hypertensive rats, and, if so, whether these changes were similar in these three models of hypertension. Rings of thoracic aorta were p...
