Drugs that inhibit prostaglandin (PG) biosynthesis improve hemodynamics and survival in experimental endotoxic and septic shock. The therapeutic utility of these agents in the management of septic patients may be limited, however, by their tendency to decrease renal blood flow (RBF) in animals and humans stressed by experimental manipulations or disease(More)
Acute, overwhelming sepsis or endotoxemia in experimental animals is associated with increased circulating levels of thromboxane (Tx)B2 (stable metabolite of TxA2) and 6-keto PGF1 alpha (stable metabolite of prostacyclin). The purpose of the present investigation was to determine the plasma prostanoid response to sepsis using an animal paradigm in which the(More)
Although some data suggest that macrophages in the reticuloendothelial system (RES) are important sources of thromboxane A2 (TxA2) and prostacyclin (PGI2) during endotoxic shock, we are unaware of data documenting the ability of hepatic macrophages (Kupffer cells) to release either TxA2 or PGI2 when exposed to lipopolysaccharide (endotoxin, LPS). In this(More)
