The work has been aimed at an analysis of accidents at work occurring throughout 1981-1982 at the Belchatów Industrial District. The most common causes of accidents at work have been direct factors resulting mainly from workers' inadvertence or recklessness, improper performance of occupational tasks, lack of appropriate tools, and settlement of private affairs at work. The incidence of accidents at work might be reduced by compliance with safety-and-hygiene-of-work rules, better supervision, work organization and efficient working tools.

The work is a continuation of studies of accidents at work at the Belchatów Industrial District. Analysed have been indirect factors causing accidents at work. Those factors were found to cause accidents much more often than the direct ones. They are particularly significant for young workers. The season, month, day of month, consecutive working hour and climate did not significantly affect the frequency of accidents.

Health effects of accidents at work at the Belchatów Industrial District have been investigated. Most injuries due to accidents have been bruises, wounds and bone fractures of upper and lower limbs. Much less frequent, as compared to other industrial plants, are injuries of head, chest and abdomen. The causes of those injuries have been discussed. In addition, the activities of occupational health services have been analysed.

Effect of Venoruton on the factor XIII activity in rat plasma.

The effect of Venoruton [O-(beta-hydroxyethyl)-rutoside] on the activity of factor XIII in rat plasma was studied in vivo. The drug was administered to the animals intragastrically 6 times a week during 90 days in doses of 5 mg/100 g body weight. An about twofold increase in factor XIII activity beginning after several days of treatment and lasting for several weeks was observed. Then an attenuation of factor XIII activity down to the control level took place in spite of systematic Venoruton administration. Spectrofluorimetric determinations of factor XIII activity were confirmed by thromboelastrographic studies.
