Histoenzymological study of selected dehydrogenase enzymes in Pneumocystis carinii.
Mazer, M A, Kovacs, J A, Swan, J C, Parrillo, J E, Masur, H
The metabolic activity of Pneumocystis carinii cysts was studied histochemically by a tetrazolium dye technique to assess substrate-specific dehydrogenase activity. Lactate dehydrogenase, succinate...
Gill, V J, Evans, G, Stock, F, Parrillo, J E, Masur, H, Kovacs, J A
A combination of three monoclonal antibodies, two prepared against human and one against rat Pneumocystis carinii, was used in an indirect fluorescent-antibody stain (IFA) to diagnose P. carinii in...
Natanson, C, Danner, R L, Elin, R J, Hosseini, J M, Peart, K W, Banks, S M, ...
Using different types of bacteria and a canine model simulating human septic shock, we investigated the role of endotoxin in cardiovascular dysfunction and mortality. Either Escherichia coli (a...
Bacterial lipopolysaccharides prime human neutrophils for enhanced production of leukotriene B4.
Doerfler, M E, Danner, R L, Shelhamer, J H, Parrillo, J E
Neutrophils can be "primed" for an enhanced respiratory burst by lipopolysaccharide (LPS) in concentrations measurable in patients with septic shock. Leukotriene B4 (LTB4) is the primary eicosanoid...
Natanson, C, Fink, M P, Ballantyne, H K, MacVittie, T J, Conklin, J J, Parrillo, J E
A canine sepsis model that simulates the human cardiovascular response to septic shock was produced in 10 conscious unsedated dogs by implanting an Escherichia coli-infected clot into the peritoneum,...
Parrillo, J E, Burch, C, Shelhamer, J H, Parker, M M, Natanson, C, Schuette, W
We have previously described a subpopulation of patients with septic shock who had a reversible depression of radionuclide-determined left ventricular ejection fraction (EF). To investigate the...
Inhibition of endotoxin-induced priming of human neutrophils by lipid X and 3-Aza-lipid X.
Danner, R L, Joiner, K A, Parrillo, J E
Lipid X, a precursor of lipid A (the toxic moiety of endotoxin), has been shown to protect animals from the lethal effects of endotoxin challenge. We investigated the mechanism of action of lipid X...
