Improved contractile performance of right ventricle in response to increased RV afterload in newborn lamb.

Pulmonary hypertension results in an increased afterload for the right ventricle (RV). To determine the effects of this increased afterload on RV contractile performance, we examined RV performance before and during 4 h of partial balloon occlusion of the pulmonary artery and again after releasing the occlusion in nine newborn lambs. RV contractile performance was quantified by indexes derived ...

Mathematical modeling of respiratory system mechanics in the newborn lamb.

In this paper, a mathematical model of the respiratory mechanics is used to reproduce experimental signal waveforms acquired from three newborn lambs. As the main challenge is to determine specific lamb parameters, a sensitivity analysis has been realized to find the most influent parameters, which are identified using an evolutionary algorithm. Results show a close match between experimental a...

Influences of hypercapnia on cardiac function in the newborn lamb.

There is an abundance of evidence which suggests that hypercapnia impairs the performance of isolated heart-lung preparations, and that this is primarily consequent to diminished contractility of the myocardium.'7 Patterson' showed that the cardiac depressant effect of CO2 could be prevented largely by the addition of epinephrine. In intact adult dogs acidosis produced by CO2 retention causes s...

The Ultrastructure of Taste Buds in the Newborn Lamb

Tichy F.: The ultrastructure of Taste Buds in the Newborn Lamb. Acta vet. Brno, 61, 1992: 83-91. The ultrastructure of taste buds on circumvallate papillae collected from the tongues of three lambs on the day of birth was studied. Of special concern were the composition of the bud from dark, light and receptor cells, formation of the taste pore and the presence and nature of contacts of intrage...

Response to Ischemia and Infusion of Alkali

A B S T R A C T Myocardial cell pH has been measured with 5,5-dimethyl-2,4-oxazolidinedione (DMO) in intact anesthetized dogs by a transient indicator dilution technique. Bolus injections of labeled DMO, vascular, extracellular, and water indicators were made into the anterior descending coronary artery, and blood samples were collected from the great cardiac vein. The steadystate distribution ...
