OBJECTIVE
Nitric oxide (NO) induced tissue damage has been implicated in the pathogenesis of several diseases. Although recurrent/chronic tonsillitis and hypertrophy are still the most frequent surgical procedures carried out on children in order to cure these pathologies, etiopathogenetic
Alkaline phosphodiesterase I activity is demonstrable in lysates of mouse resident peritoneal macrophages (1.43 mU/mg), endotoxin-stimulated macrophages (1.36 mU/mg), and thioglycollate-stimulated macrophages (3.91 mU/mg), as well as in the lysates of several mouse cell lines. The enzyme showed
Intact rabbit neutrophils were found to express phospholipase A2 activity against [14C]oleate-labeled autoclaved Escherichia coli. Cells obtained 12-14 h rather than 4 h after intraperitoneal injection of glycogen had approximately threefold higher activity. The higher activity was due neither to
Many idiosyncratic non-steroidal anti-inflammatory drugs (NSAIDs) cause GI, liver and bone marrow toxicity in some patients which results in GI bleeding/ulceration/fulminant hepatic failure/hepatitis or agranulocytosis/aplastic anemia. The toxic mechanisms proposed have been reviewed. Evidence is
The effect of tartrazine on prostaglandin production was evaluated in several in vitro systems in order to elucidate the interrelationship between aspirin-sensitive asthma and tartrazine. Unlike the nonsteroidal anti-inflammatory drugs, tartrazine did not inhibit cyclooxygenase activity in sheep
