The Binational Arsenic Exposure Survey (BAsES) was designed to evaluate probable arsenic exposures in selected areas of southern Arizona and northern Mexico, two regions with known elevated levels of arsenic in groundwater reserves. This paper describes the methodology of BAsES and the relationship between estimated arsenic intake from beverages and arsenic output in urine. Households from eigh...

The present work was undertaken in an attempt to throw more light on the metabolism of vitamin B in the newborn infant, and, in particular, by means of balance experiments, to seek evidence of the biosynthesis of B vitamins in the intestinal tract during the first week after birth. The investigations were confined to aneurin, riboflavin, and nicotinic acid and its metabolites. Very little work ...

Purpose: To investigate the effect of Flueggea leucopyrus Wild aqueous extract (FLAE) on the urinary output of rats. Method: Three different doses of FLAE (500, 1000 and 1500 mgkg), furosemide (13 mg kg as diuretic reference) and distilled water (as control) were orally administered to healthy adult hydrated rats. Cumulative urine output was monitored hourly over 6 h. Selected urinary parameter...

OBJECTIVE To simultaneously model plasma dilution and urinary output in female volunteers. METHODS Ten healthy female non-pregnant volunteers, aged 21-39 years (mean 29), with a bodyweight of 58-67 kg (mean 62.5 kg) participated. No oral fluid or food was allowed between midnight and completion of the experiment. The protocol included an infusion of acetated Ringer's solution, 25 ml/kg over 3...

Lower urinary tract symptoms (LUTS) are quite common in aging males and these affect the quality of life an individual. Among various etiologies LUTS, benign hyperplasia (BPH) has a high prevalence. The term Mutraghata stands for low urine output due to obstruction passage urine. Mutraghata, disease Mutravaha Srotas (urinary system) described Ayurveda, closely resembles with prostatic modern me...

Proximal renal tubular function was studied in 522 consecutive patients entered into the Medical Research Council's fourth myelomatosis trial. Assessment was made at presentation after a 48 h period of hydration but before administration of chemotherapy. The most common abnormalities in the urine other than light chain proteinuria were raised concentrations of the low molecular weight proteins ...

Amin A. Nanji, Division of Clinical Chemistry, Vancouver General Hospital, Vancouver V5Z1M9 (Canada) Dear Sir, Analytical and biologic variations in serum and urinary creatinine may account for up to 33% variability in creatinine clearance calculations [1]. We wish to report on the marked variability of creatinine clearance in patients receiving total parenteral nutrition (TPN). 18 of 93 patien...
