Coronary 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...

دراین پروژه به بررسی مدل سازی خشک کردن مواد غذایی با استفاده از هوای خشک در خشک کن آزمایشگاهی نوع سینی دار پرداخته شده است. برای آنالیز انتقال رطوبت در طی خشک شدن به طریق جابجایی، یک مدل لایه نازک برای انتقال رطوبت، مبتنی بر معادله نفوذ فیک در نظر گفته شده است که شامل انتقال همزمان جرم و انرژی بین فاز جامد و گاز می باشد. پروفایل دما و رطوبت برای سه نوع ماده غذایی شامل سیب زمینی، سیب و موز در طی...
15 صفحه اولInfluence of norepinephrine and digitalis on myocardial oxygen consumption in the newborn lamb.
The relationships between cardiac performance and oxygen usage were explored in 19 newborn lambs (5 hours to 8 days old), and the influence of inotropic stimulation was studied. A preparation was developed to measure coronary sinus flow and myocardial oxygen consumption (MVo2) under controlled hemodynamic conditions. Using a gelatin injection technique, we determined that more than 905? of the ...
متن کاملMyocardial buffering capacity and high-energy phosphate utilization during hypothermic circulatory arrest and recovery in the newborn lamb in vivo.
UNLABELLED The purpose of this study was to measure myocardial buffering capacity and adenosine triphosphate utilization rates in the newborn animal in vivo during hypothermic circulatory arrest and recovery. METHODS These studies were performed with 31P magnetic resonance spectroscopic techniques, which supplied a 12- to 16-second time resolution, to monitor intracellular pH and phosphocreat...
