Endothelial Ectoenzyme Assays Estimate Perfused Capillary Surface Area in the Dog Lung
Autor: Scott A. Barman, I. C. Ehrhart, John D. Catravas, W. F. Hofman, Stylianos E. Orfanos
Publikováno v: Microvascular Research. 54:145-155
Whether the pulmonary vascular bed accommodates flow-induced increases in blood volume mainly through recruitment of previously unperfused capillaries or distension of already perfused vessels remains controversial. The modified first order reaction

Effect of high blood flow on pulmonary vascular permeability to protein
Autor: W. F. Hofman, Stylianos E. Orfanos, I. C. Ehrhart, John D. Catravas, Laryssa McCloud
Publikováno v: Journal of Applied Physiology. 76:2342-2347
The elevated cardiac output associated with exercise increases lung lymph flow and may increase extravascular lung water. However, it is not known if extremely elevated cardiac output alters pulmonary vascular permeability. The hematocrit-protein met

Segmental vascular pressures in lung embolism
Autor: W. F. Hofman, I. C. Ehrhart
Publikováno v: Journal of Applied Physiology. 74:2502-2508
Average microvascular filtration pressure and vascular permeability measures were obtained in 100-microns glass bead-embolized dog lung lobes randomly assigned to groups in which isolated perfusion was designed to produce weight gain (edema groups) o

Relationship of fluid filtration to lung vascular pressure during edema
Autor: I. C. Ehrhart, W. F. Hofman
Publikováno v: Journal of Applied Physiology. 70:202-209
Effect of edema on the relationship between rate of fluid filtration and vascular pressure was studied in ventilated isolated dog lung lobes blood-perfused at constant flow. Constant rate of lobe weight gain (S), representing transvascular fluid flux

Pulmonary vascular reactivity and permeability to alveolar hypoxia in the dog
Autor: I. C. Ehrhart, W. F. Hofman
Publikováno v: Journal of Applied Physiology. 69:1828-1835
Hemodynamics and vascular permeability were studied during acute alveolar hypoxia in isolated canine lung lobes perfused at constant flow with autogenous blood. Hypoxia was induced in the presence (COI + Hypox, n = 6) or absence (Hypox, n = 6) of cyc

Vascular recruitment increases evidence of lung injury
Autor: W. F. Hofman, John D. Catravas, Laryssa McCloud, Dale W. Sickles, Stylianos E. Orfanos, I. C. Ehrhart
Publikováno v: Critical care medicine. 27(1)
Objective: Changes in pulmonary blood flow rate can alter the size of the perfused pulmonary capillary surface area. We tested the hypothesis that full recruitment of the pulmonary vascular bed may decrease evidence of lung injury by recruiting less

Methylene blue restores vasodilation to bradykinin after inhibition of nitric oxide production in the isolated dog lung
Autor: I. C. Ehrhart, W. F. Hofman, Jozsef Endrédi, Michael B. Shapiro
Publikováno v: Journal of vascular research. 33(4)
Methylene blue (MB) is a widely used putative inhibitor of nitric oxide (NO)-dependent responses, particularly in cell culture and vascular ring studies. MB is postulated to diminish vasodilation to NO either by preventing activation of guanylate cyc

Effect of aspirin on vascular tone and reactivity to vasoactive amines in the dog lung
Autor: W F, Hofman, J, Fravel, I C, Ehrhart
Publikováno v: Research communications in chemical pathology and pharmacology. 78(1)
The effect of increasing blood levels of aspirin on pulmonary hemodynamics and pressor response to vasoactive amines was examined in the isolated canine lung lobe, blood perfused at constant flow. At steady state lobar vascular resistance (LVR), lobe
