Toxicosis produced by nitrates and related compounds is a problem in man and in domestic animals. The most prominent effect of nitrate and nitrite is the conversion of hemoglobin to methemoglobin. Nitrate must be reduced to nitrite before excessive -methemoglobinemia occurs. Nitrites are therefore several times more toxic than nitrates. -· Pharmacologically, KN03 had been used as a diuretic, an...
The content of nitrates and nitrites in agricultural products has been assessed as an indicator of the quality of the products and has important health influences 1. Changes in patterns of agricultural practice, food processing and industrialization have impacted accumulation of nitrates/nitrites in the environment. Intensive farming practice has resulted in an increasing use of nitrogen-based ...
BACKGROUND Dietary intake of nitrates, nitrites, and nitrosamines can increase the endogenous formation of N-nitroso compounds in the stomach. Results from animal studies suggest that these compounds might be teratogenic. We examined the relationship between maternal dietary intake of nitrates, nitrites (including plant and animal sources as separate groups), and nitrosamines and several types ...
Aim. To assess laboratory markers of hemodynamic status in patients with moderate to severe COVID-19. Materials and Methods. Here we examined 15 COVID-19 16 critically ill patients. The control group consisted 20 healthy volunteers. levels endothelin-1, brain natriuretic peptide (BNP), N-terminal pro-brain (NT-proBNP) were measured by enzyme-linked immunosorbent assay. amounts nitrites (NO 2 ) ...
