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...
متن کاملMathematical 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...
متن کاملCoronary flow and myocardial oxygen metabolism in the newborn lamb.
Analysis of factors which may influence oxygen metabolism of the heart has received much attention since the early part of this century (1). Quantitative measurements of coronary blood flow and myocardial oxygen consumption (MVO,) have been accumulated from both human and animal studies (2, 3). These studies were uniformily concerned with adults, however, and virtually no information is availab...
متن کاملAutonomic influences on cardiac function in the newborn lamb.
The influences of reflexly induced changes of sympathetic outflow to the heart on left ventricle contractility, heart rate, and systemic vascular resistance were studied in 26 technically successful experiments with newborn lambs ranging in age from 1 to 11 days. Reduction of brachiocephalic artery perfusion pressure was associated with a large increase of heart rate and of systemic vascular re...
متن کاملInfluences 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...
