[Protein fractions in workers exposed to organic solvents].

Industrial workers exposed to organic solvents were subject to examinations consisting in the assessment of the composition of serum proteins. The analysis revealed frequent shifts in protein fraction pattern. It was noted that the increased concentrations of organic solvents metabolites in urine have been usually accompanied by the increased gamma-globulins levels with a simultaneous decrease in albumin fraction and plasmatic index.

[Evaluation of the usefulness of enzyme tests for the diagnosis of the effects of various organic solvents in the conditions of occupational exposure].

The aim of the study was to evaluate the suitability of enzymatic tests for estimating the effects of organic solvents upon the organisms of daily exposed workers. The analysis was undertaken in 572 workers exposed to such solvents as toluene, xylene, cresols and benzine. Periodical examination was carried out for the purposes of the study. The level of excreting organic solvents' metabolites in urine and serum enzymes' activity were determined. Also, the activity of alanine and aspartate aminotransferases and of plasmatic cholinesterase was determined. The results of the study support the necessity of applying the enzymatic tests as a basic method of evaluating the toxic activity of organic solvents.

[Superoxide dismutase activity of erythrocytes and their osmotic fragility].

Blood samples were obtained from 15 diabetic patients (type I) and 10 healthy subjects. Erythrocyte superoxide dismutase activity, Heinz bodies and osmotic fragility were determined. Our results suggest that decreased activity of erythrocyte SOD predisposes to denaturation of haemoglobin (Heinz bodies) and haemolysis (increased osmotic fragility).

[Factors influencing fluorine absorption and excretion in people and animals].

Factors that make fluorine absorption and excretion easy or difficult from organisms of people and animals have been analysed. Fluorine is easily absorbed in presence of alimentary fat from soluble dust, from water environment, especially from an acid one. Compounds of calcium, magnesium, aluminium, microelements and various high protein diet make fluorine absorption difficult. Compounds that easily absorb fluorine, namely compounds of calcium, magnesium, aluminium, boron, phosphorus and vitamin C as well as climatic conditions (increasing perspiration) make fluorine excretion from organisms easy. Fluorine excretion is made difficult in the period of intensified mineralization and lactation processes. The age of the person is also important.

Interaction of sodium, lithium, caesium, and potassium ions with ascorbyl radicals.

The influence of the concentration of sodium, lithium, caesium, and potassium ions as well as of the ionic strength of the solutions used on the dismutation rate of ascorbyl radicals has been investigated. While the dismutation rate was not influenced by Li+, it decreased, however, with increasing concentrations of the other ions investigated. The largest effect was obtained with Na+. This change in dismutation rate indicates a stabilizing effect on ascorbyl radical by these ions.
