Blood pressure was measured in the north and in the south of the People's Republic of China in 1002 men and 1006 women. The 24-hour urinary excretion of sodium, potassium, calcium, magnesium, and creatinine was measured, and the relationship between urinary cations and blood pressure was studied. Blood pressure and 24-hour sodium excretion were higher in northern China than in southern China. W...

This paper reviews the effects of lead (Pb), cadmium (Cd), and arsenic (As) on the mitrochondrion with emphasis on alteration of mitochondrial heme biosynthetic pathway. The information was used to examine results of a Pb x Cd x As interaction study which employed urinary porphyrin excretion patterns as one assessment criterion. Data from the study showed that dietary Pb produced increased uri...

Case Report The patient was a girl of 24 who had worked for six months in a factory " throwing " coils. This process consisted of calibrating coils containing mercury for use as pressure gauges. On an average, two or three coils a day burst during testing, so that the work bench was usually contaminated with metallic mercury. Despite warnings about the danger of ingesting mercury, she ate sweet...

BACKGROUND We studied urinary nitrate and cGMP excretion rates, indices of systemic NO formation, and plasma concentrations of L-arginine and the endogenous NO synthase inhibitor asymmetrical dimethylarginine (ADMA) and its inactive stereoisomer, symmetrical dimethylarginine, in 77 patients with peripheral arterial occlusive disease (PAOD) in Fontaine stages IIb through IV and in 47 young and 3...

OBJECTIVE To determine fluoride excretion under various conditions of fluoride intake and to estimate the fractional urinary excretion of fluoride in individual children participating in a school milk fluoridation scheme. DESIGN In the first part of the study, individual urine samples were collected from each of eight 4 to 5-year-old children for a continuous period of 55 h. For each child (n...

Using transgenic models and in vitro assays, this study examined the effect of Mg 2+ on regulating urinary excretion Ca via activation -sensing receptor-claudin 14 (CLDN14) pathway. The suggests that CLDN14 is unlikely to play a significant role compensatory response hypermagnesemia.

The possibility that hyperlipidemia and an increase of mononuclear cells in the glomeruli could participate in the pathogenesis of minimal change glomerulopathy was evaluated in puromycin aminonucleoside (PAN) nephrosis in rats. Significant increases in intraglomerular CD4-, IL-2-receptor (R)- and ED-1-positive cells were found in PAN rats. Urinary protein excretion and mononuclear cells in the...

Workers at a printing plant exposed to low concentrations of toluene (43-401 mg/m3, median 155 mg/m3) had increased urinary D-glucaric acid (3.55-5.12 mmol/mol creatinine) excretion at the end of the shift compared with controls (2.45-3.35 mmol/mol creatinine). No increase was found after the summer holiday (1.92-2.89 mmol/mol creatinine) but excretion had increased two weeks later (4.05-5.55 m...

Savage, M. O., Wilkinson, A. R., Baum, J. D., Roberton, N. R. C. (1975). Archives of Disease in Childhood, 50, 709. Frusemide in respiratory distress syndrome. The effect of frusemide on urinary volume, urinary sodium excretion, and urinary calcium excretion in 7 premature infants with severe respiratory distress syndrome (RDS) has been studied. The results are compared with similar measurement...
