| Popis: | Goats were divided into three groups and given infusions of live Escherichia coli bacteria. Group I received no treatment, group II was treated with indomethacin (a cyclooxygenase inhibitor), and group III with dazoxiben (a thromboxane synthase inhibitor). Double indicator-dilution extravascular lung water (EVLW) in group I was significantly different from the treated groups. There was an early increase in EVLW in group I and group III but not in group II animals. At 6 h EVLW's in group I, group II, and group III were 100, 45, and 30% above base line, respectively. Lymph flow (QL) and lymph-to-plasma protein ratio (L/P) was not statistically different between groups. Estimated total fluid filtration [QL + d(EVLW)/dt] in group I and III was markedly elevated between 0 and 1.5-2 h after E. coli infusion. Cardiac output (QT) decreased to 40% of base line in group I, and it decreased slightly in group II because of the indomethacin but did not decrease after E. coli. QT decreased in group III but recovered more rapidly than group I. Mean pulmonary arterial pressure increased more rapidly in group I and reached a higher peak than either treated group. At 6 h these groups had similar pulmonary arterial and pulmonary arterial wedge pressures. We conclude that 1) indomethacin but not dazoxiben blocks the early increase in total fluid filtration after bacterial infusion, 2) dazoxiben does not prevent the increased endothelial permeability resulting from infusion of live bacteria, and 3) indomethacin may somewhat ameliorate the endothelial permeability change.(ABSTRACT TRUNCATED AT 250 WORDS) |
