Studies on Major and Trace Element Content in Human Tissues

Abstract

This paper reports the results of analysis of human tissue samples collected from Bombay (India). Data on elemental content in twenty tissues/organs collected from twenty cases of instantaneous accidental death of normal adults are presented.The samples were analysed for Na, K, Rb, Ca, Mg,Fe, Mn, Cr, Cu, Zn,Pb, Te andP. All the elements except P were determined by the technique of atomic absorption spectrophotometry. Estimation of P was carried out by the "Molybdenum Blue" method. The statistical treatment of the data obtained is given and the results so obtained are compared with those of ICRP.

The Effects of Phenytoin on Serum and Organ Concentrations of Zinc and Copper in Cat

“…The cause of the fatty degeneration observed in the present study is unknown. However, the cat has normally low Cu concentrations in the liver compared to humans (Soman et al, 1970) and may be sensitive to an increased accumulation of Cu. Fatty degeneration and Cu accumulation have been found in patients with Wilson's disease during early childhood (Goldfischer and Sternlieb, 1968).…”

Factors influencing breast elasticity measured by the ultrasound Shear Wave elastography – preliminary results

“…Their proportions, connective tissue content, size, shape also vary over the time in the same woman (e.g. during the menstrual cycle) and between women [1,3,4]. There are many studies indicating that the increase in breast density as measured e.g.…”

Lead content of neuromuscular tissue in amyotrophic lateral sclerosis: case report and other considerations

“…Similar analysis of the standardmaterials used to fix the specimens failed to show detectable quantities of lead and therefore established that the lead was associated with the tissue. These data show that in this case the lead levels in nerve, muscle, and spinal cord were comparable in magnitude to those found in similar tissues many years ago in a particular case of lead paralysis (Herter, 1895 Lead in ALS and control groups A lead content (,ug/g dry weight) of 17-7 and 21-2 in heart and skeletal muscle, respectively, is much higher than the recently reported values of 0-26-0-30 in either muscle for a large series of necropsies not involving ALS or known exposure to lead (Barry and Mossman, 1970;Soman et al, 1970). This observation combined with the need for more data on the lead content of spinal cord and nerve tissue suggested measurements by emission spectrography of the lead present in nerve, cervical segment of spinal cord, and skeletal muscle tissue in two series-one involving ALS (ALS group), and another not involving either ALS or known lead exposure (control group).…”
