An attempt was made to formulate reference ranges of elemental concentrations for 15 trace elements in selected human tissues and body fluids. A set of samples consisting of whole blood, blood serum, urine, milk, liver and hair were chosen and considered for 15 elements of biological significance:...

Based on data from 3 series of experiments with rats given drinking water of hardness 0.5, 4.0 or 7.0 mEq/litre with arsenic 0.292, 0.0584 or 0.01168 mg/kg diet daily for 30 days maximum safe concentration of As was estimated as 0.01 and 0.05 mg/litre for drinking water with hardness less than or...

Reference intervals for normal concentrations in blood of thiamin, riboflavin, vitamins E, D, and A, β-carotene, and folic acid were estimated from a selected sample of people attending a health centre or being examined in occupational health services in France. This reference sample consisted of...

Population data are presented for up to 30 elements in urine, scalp hair, air filters and faeces, and up to 44 amino acids and intermediary metabolites in urine. The multi-element data are derived almost exclusively via a vacuum inductively coupled argon emission spectrograph. Increases and...

Anthropometric indices are presented for representative samples of elderly people in South Wales, based on over 1500 subjects seen during community surveys. Body mass index declined with age after 70 years in both men and women. Estimates of fat and muscle volume based on upper arm measurements...

Evaluation of blood pressure in children should include allowances for increases associated with age, height and weight, and guidelines for those factors are becoming available. Still to be determined is the degree of increase associated with sexual maturity.

For 6 months 6 groups of 10 rats were given drinking water with hardness 0.463, 3.97 or 7.28 mEq/litre and silicon 1, 12.5 or 25 mg/litre. Results indicated that for drinking water with hardness 2.5 to 7 mEq/litre maximum permissible Si content is 12.5 mg/litre. For water with hardness less than...

Descriptive analysis of foods involves the communication of sensory concepts which are defined using standard stimuli. The concept created by a single NaCl standard stimulus was measured as a set of probabilities. It was not the same for each judge. Disagreement between judges can thus be caused by ...

Mean serum transferrin concentration was 2.15 g/litre in 34 newborn infants. The value increased to about 3.10 by 10 months then decreased to 3.0 g/litre at 24 months and 2.80 g/litre at 48 months old. Mean transferrin concentration of 139 children 4 to 18 years old was 3.15 g/litre. Reasons for...

Serum ferritin concentrations in 64 healthy women ranged from 4 to 152 ng/ml and from 18 to 284 ng/ml in 32 healthy men. Of 58 patients with iron-deficiency anaemia 54 had serum ferritin concentrations less than 18 ng/ml, serum ferritin was above the upper normal limit in 8 people with...
