Sublethal effects of textile dye stuff effluent on selected oxidative enzymes and tissue respiration of Cyprinus carpio (Linn.).

Toxic effects of sublethal concentration of dye stuff effluent on succinic dehydrogenase (SDH) and lactic dehydrogenase (LDH) activities and tissue respiration were studied in C. carpio. While the sublethal exposure significantly reduced SDH activity and tissue respiration, LDH activity increased in gill, brain, liver, muscle and kidney. The maximum inhibition of SDH activity (74%) was recorded in gill and the minimum (38%) in liver. The percentage reduction of oxygen consumption in the tested tissues was in the order of gill greater than brain greater than liver greater than muscle greater than kidney. The muscle showed the highest level (96%) of increase in LDH activity whereas the kidney cells showed the minimum increase. Exposure to sublethal concentration suppressed the aerobic respiration and triggered the anaerobic respiration.

[Unusual wound morphology after textile penetration by the automatic rifle (StG) 58. A case report].

Technical characteristics of the used fire-arm and ammunition, the firing range and the shot through garments of the victim are essential factors, that exercise an influence on the appearance of gunshot injuries. An exemplary case-report shall emphasize the importance of these factors. It deals with a suicidal double-shot fired from an automatic rifle by a young soldier. The wounds were localized in the left chest region and the adjacent skin was blackened by soot in a remarkable geometrical pattern, although an ammunition with a smokeless charge has been used. By means of comparative shots we have good reasons to suppose this phenomenon to be caused by rests of gun powder and pressure of the explosion gas leaved in the barrel after the first shot. The second projectile pushed out this explosion gas to the skin that had been uncovered in a star-shaped way by the first shot.

[Textile intolerance in atopic eczema--a controlled clinical study].

In patients suffering from atopic dermatitis (AD), we often find intolerance reactions against wool, whereas irritation by synthetic fibers is still a matter of discussion. In a randomized clinical study on 55 patients with AD and 31 healthy controls, we investigated the irritative capacity of poncho-like shirts made of 4 different materials (A: cotton; B, C, D: synthetics of different fiber structure). The intensity of itching or discomfort due to repeated wearing of these shirts was evaluated by means of a point system (max.comfort = 10 points, max. discomfort = 1 point). Our study clearly showed that the irritative capacity of synthetic shirts is significantly higher in patients with AD, while cotton shirts were best tolerated. We also observed significant difference regarding the surface structure and diameter of the synthetic fibers under investigation.

[The importance of work conditions in the textile industry to worker absenteeism].

A study was performed in the "Belgrade Wool Co." as a retrospective epidemiological investigation, for a three-year period (1985-1987), on a sample of 134 blue-collar female workers. The following statistically significant facts were established: in favourable working conditions (sewing department) the older workers (above the age of 35 years) were absent from work because of illness longer than the younger workers; the number of the younger workers (age 35 years or under) with sick absences increased as working conditions worsened (wool-mills compared to sewing departments). Respiratory diseases made the most frequent cause of absence from work. Harder working conditions influenced the morbidity structure as cause of absenteeism resulting in the rise of prevalence of mental disorders among the younger workers, and of locomotor and circulatory diseases among the older ones. The younger workers showed a rising trend in the severity and frequency of injuries as causes of absence from work, which correlated with the degree of deterioration of working conditions. Finally, under extremely hard working conditions (wool-mills) the rate of occupationally induced injuries among the younger workers was as much as three times higher than among the older ones, and the duration of sick absences was longer.

Mutagenic and genotoxic activity of chosen dyes and surface active compounds used in the textile industry.

This study was designed to investigate the mutagenic and genotoxic properties of ten dyes and four surface active compounds using Salmonella/microsome assay and the micronucleus test. Five of the investigated dyes (Acid Blue 7, Acid Green 16, Direct Black 19:1, Basic Red 22, Basic Orange 28) possessed mutagenic activity with regard to test strains of Salmonella. In addition, all of them increased the frequency of micronucleated polychromatic erythrocytes in the bone marrow of mice. Three other compounds (Acid Blue 62, Direct Yellow 12, Direct Red 81), which were not mutagenic in the Salmonella/microsome assay, were genotoxic in the micronucleus test. The other two dyes (Reactive Blue 13, Acid Red 213), as well as tested surface active compounds, did not exert mutagenic and genotoxic effects, and therefore, it is most probable that they do not have carcinogenic properties. Besides, it was noted that Acid Blue 62, Direct Black 19:1, Direct Red 81 and Basic Orange 28 cause a significant decrease in the ratio polychromatic to normochromatic erythrocytes in the bone marrow of mice, which means that, at the doses used in the experiment, they are toxic to the erythrocyte series cells of bone marrow. The other compounds under consideration have no such effect.

[Evaluation of somatic development, physical fitness and motor skills of girls from the Textile Technical College in Lódź (I)].

Thirty-five girls from a technical college (TC) and forty-five from a grammar school (GS) (a control group) were included in a long-term examination. Somatic traits have been investigated for 4 years, while aerobic capacity and motor efficiency have been studied for 3 years. The preliminary selection was noticed in girls--candidates to technical college and grammar school. These two groups of girls differed in respect of social factors and somatic predisposition. At the beginning of the examination the girls from the technical college revealed a considerably lower motor efficiency as compared to those from the GS. After 3 or 4 years of learning traits of the body length were still weaker in the girls from the technical college. However, they had a more massive skeleton, stronger trunk muscles and stronger hands. In addition, these girls were characterized by a remarkable improvement of general physical efficiency, particularly endurance, speed and nimbleness. In the final stage of the study in all girls from both TC and GS aged 18 lower aerobic capacity in comparison with data from the previous year was found, which could results from inefficient physical activity during the educational process. This fact may be especially unfavourable for the girls from TC as far as their future profession is concerned.
