متن کاملA method for urine collection in infants.
A simple, inexpensive, non-invasive method for urine collection was used in 28 consecutive infants for periods of 48 hours (n = 10) and 72 hours (n = 18). The incidence of urine collector detachment was low on the first and second days (< 4%) and increased significantly on the third day (28%). Volume of urine leaked was < 4% of the total volume collected daily. This method is applicable to both...
متن کاملDetermination of nitrite and nitrate in stored urine.
To the Editor: Nitric oxide (NOz) plays an important role both in maintaining normal homeostasis and in the pathogenesis of various disorders (1). NOz has a short biological half-life and is rapidly converted into its stable metabolites, nitrite and nitrate (1, 2). In plasma, nitrite is rapidly oxidized to nitrate (2). Determination of nitrite and nitrate (NOx) in body fluids like plasma and ur...
