The establish a threshold dose, an acute experiment was carried out by 30 min. radiation of the rabbit's shaved head with all ranges of infrared, 200 W/m2, 350 W/m2 and 500 W/m2 intensities. Irradiation was prolonged up to 2 hrs. Having established the threshold dose, a chronic (5 months') experiment was carried out, irradiating 9 rabbits' skin (in 3(More)
In order to determine biological aggressiveness of settled dusts (mechanical, crumbled) and dusts collected using the gravimetric method, experimental studies were carried out, including: 1) evaluation of the physicochemical parameters (size of dust particles, content of silica, metals and other chemical compounds), 2) evaluation of the haemolytic activity,(More)
Based on the data collected by the Provincial Regional Administration Unit for Control of Epidemics and Hygiene in Katowice, dust concentration at the MAKOSZOWY Coking Plant in Zabrze at 18 work-places exceeded the TLV's. The purpose of this study was to determine changes within the respiratory systems of experimental animals exposed to intratracheal(More)
In order to evaluate biological effects of Austrian and Italian talc, pulmonary and hemolytic tests as well as pathomorphological examinations were performed. 120 Wistar rats divided into 5 groups were given intratracheally 50 mg of the examined talc dust suspended in 0.5 ml of 0.9 NaCl. The control group received one 0.5 ml dose of NaCl. The observation(More)
Experimental investigation was conducted in order to evaluate the impact of the Rokafenol N-8 detergent upon the development and course of experimental pneumoconiosis caused by mine dusts. albino rats were used for the experiment. Methodological assumptions were elaborated based on the analogy with the conditions observed at the workplaces, where means of(More)
Experiments aimed at testing the toxicity of the detergent (Rokafenol N-8) and determination of the biological effect of the detergent and mine dust with respect to histopathological changes in some internal organs were performed on albino rats and rabbits. The acute toxicity testing was based on determination of the medial lethal dose (LD50) after(More)
Comparative studies on the impact of the detergents Emulkop and Rokafenol N-8 upon the development and course of experimental pneumoconiosis caused by mine dusts were carried out. Albino rats and rabbits were used for the experiment. Methodological assumptions were based on the analogy with the conditions observed at the workplaces where some means of dust(More)
The studies aimed at determining the changes in respiratory system of animals after intratracheal administration of settled dusts sampled from seams 116 and 188 in Janina colliery and seams 314 and 317 in Victoria colliery. For comparison, dusts sampled gravimetrically from a/m seams in Janina and Victoria collieries were intratracheally administered to(More)
