We measured transpulmonary indicator dilution curves of 51Cr-erythrocytes, 125I-albumin, 14C-urea, and 3H-water before and six and 24 hours after operation in seven patients undergoing aortocoronary bypass (ACB) and eight patients undergoing mitral valve replacement (MVR). We calculated cardiac output (CO), extravascular lung water (EVLW), the difference between 125I-albumin and 51Cr-erythrocyt...

STARZECKI, B., AND D. F. J. HALMAGYI. Absorption of inhaled water in experimental Fulmonary edema and embolism. Am. J. Physiol. 201(s) : 762-764. 1961. -The effect of pulmonary edema and pulmonary embolism on the rate of absorption of standard amounts of inhaled fluids was investigated in rats. Relative lung weight ( = lung weight in per cent of body wt.) was used as an index of the fluid conte...

A single intratracheal injection of bleomycin in rats induced, 4 days later, a considerable accumulation of hyaluronan (hyaluronate, hyaluronic acid) in the lung tissue. This connective tissue reaction was quantified biochemically by analysing hyaluronan (HA) in bronchoalveolar lavage fluid (BAL) and lung tissue extracts. The molecular weight of the HA recovered during lavage was 0.2-0.3 X 10(6...

BACKGROUND Studies using transthoracic thermodilution have demonstrated increased extravascular lung water (EVLW) measurements attributed to progression of edema and flooding during sepsis and acute lung injury. The authors hypothesized that redistribution of pulmonary blood flow can cause increased apparent EVLW secondary to increased perfusion of thermally silent tissue, not increased lung ed...

We previously showed that pacing-induced heart failure in dogs results in an enhancement of pulmonary vascular reactivity. In the present study we hypothesized that enhanced matrix deposition and structural remodeling of lung resistance microvessels would underlie these functional changes. Using biochemical measures, we found no difference in the normalized lung content of hyaluronan, uronic ac...

Abstract Funding Acknowledgements Type of funding sources: Foundation. Main source(s): Swedish Heart-Lung Foundation, Stockholm, Sweden. Introduction Severe primary mitral valve regurgitation (MR) is associated with significant hemodynamic changes in the cardio-pulmonary system, eventually resulting lung congestion. The gold standard for assessing volume and fraction (RegVol; RegFraction), seve...

We determined the degree of pulmonary edema at various times postembolization in mechanically ventilated dogs in which pulmonary emboli were induced with 0.7 g/kg glass beads (100 ion in diameter). All dogs received '"I-fibrinogen prior to embolization. The extravascular lung water contents -were determined at 1 or 2 hours postembolization. The increases in pulmonary arterial pressure (Pp.) and...

To see whether antihistamines could prevent and reverse histamine-induced pulmonary edema and increased lung vascular permeability, we compared the effects of a 4-h intravenous infusion of 4 mug/kg per min histamine phosphate on pulmonary hemodynamics, lung lymph flow, lymph and plasma protein content, arterial blood gases, hematocrit, and lung water with the effects of an identical histamine i...

Background: Accurate dose calculations in small beamlets and lung material have been a great challenge for most of treatment planning systems (TPS).  In the current study, the dose calculation accuracy of TiGRT TPS was evaluated for small beamlets in water and lung phantom by comparison to Monte Carlo (MC) calculations. Materials and Methods: The head of Siemens Oncor-impression linac...

in this research, some of the echo-physiological characteristics of pistachio trees were studied to understand crop response to drought stress and determine the best irrigation interval. this experiment was carried out in an orchard with a sandy loam textured soil and a commercial cultivar of pistachio named ouhadi grafted on pistacia vera l. rootstock for three years. the irrigation system sel...
