Bleomycin (BLM) is a useful anticancer agent sometimes associated with a diffuse pulmonary inflammation and fibrosis. Using an intratracheal model of BLM-induced pulmonary damage, we have further inves tigated alveolar macrophage (AM) activation following intratracheal BLM. From rats that had been treated with either a single, fibrogenic, intratracheal dose of BLM (BLM-AM) or a comparable volum...

Sir,?I would be grateful for any of your readers' comments on the following hypothesis concerning the use of methylene blue in the treatment of cholera, the argument for its use being as follows : (1) The cholera vibrio on culture produces nitrites. (2) In the human gut the cholera vibrio probably produces nitrites from nitrogenous bowel content. (3) Absorption of nitrites would occur, having b...

conclusions nitrosamine was formed with conventional potato baking methods with the most nitrosamine formation found on the surface fried samples. nitrites amount in baked potatoes decreased. generally, the amount of nitrosamine in baked potato samples was lower than acceptable limits. results fried samples that were measured by the gas chromatography method had the highest average levels of ni...

The presence of nitrates and nitrites in food is associated with an increased risk of gastrointestinal cancer and, in infants, methemoglobinemia. Despite the physiologic roles for nitrate and nitrite in vascular and immune function, consideration of food sources of nitrates and nitrites as healthful dietary components has received little attention. Approximately 80% of dietary nitrates are deri...
