The behaviour of the parasites under the influence of low temperatures was examined; they died in winter conditions, at the mean maximal temperature of -6,7°C and mean minimal one of -13,7° C.

The paper presents findings related to fighting the fire hazard at the “Pokój” mine on the example of longwall 424 in stratum 504. Until 17 April 2010, gas samples taken for analysis did not display any symptoms of an increase in the fire hazard, and the maximum Graham’s indicator was G=0.0007. In the morning of 18 April 2010, the carbon oxide sensor built into the longwall’s outlet, and the measurements taken in the longwall workings showed an increased concentration of carbon oxide, pointing to a very rapid increase in the fire hazard. In view of the above, the longwall was dammed and inerting of the area was commenced. The example of longwall 424 shows that the alteration dynamics of the fire hazard status in the area of an active longwall may be quite high. The lack of any symptoms pointing to the increase in the spontaneous fire hazard within a period of several months does not alter the fact that within just a few hours, the situation may change completely. Therefore, the elimination process of the fire hazard should be based on a continuous and comprehensive monitoring system which should include: a system of CO detectors, accurate chromatographic analyses for the whole area, use of inspection wells to adjacent and overlying workings, inspections and measurements conducted in the area by ventilation inspectors. In the case of longwall 424 in stratum 504, the capacity for rapid damming and inerting of the longwall’s area enabled the completion of the longwall’s excavation.

Artykuł przedstawia problemy i doświadczenia z prognozowaniem, wykrywaniem oraz zwalczaniem rozwoju pożaru endogenicznego w kopalni węgla kamiennego. Omówiono sposób prowadzenia rzeczywistej profilaktyki przeciwpożarowej w czasie eksploatacji ściany wydobywczej.

"Zanil" (3,3', 5,5', 6-pentachloro-2,2'-dihydroxy benzanilide) of I.C.I. production is known to be one of the most safe and effective drugs in the treatment of fascioliasis (2, 3, 1, 4). The aim of the studies undertaken was to examine the usefulness of ’’Zanil” in the control of fluke infection in Poland.

Hexachlorophen given per os in the aqueous solution in the dosis of 1,7g/100 kg of body weight, in spite of its effectiveness (about 70%) does not lend itself - in authors' opinion - for massive practical use on account of its considerable toxicity and cumbersome application (prior starvation, diet during the therapy, risk of overdosage). Bilevon M-Bayer (Bilevon 9015-Bayer) in the dosis of 0.4 g/100 kg of body weight administered by oral route in aqueous solution is highly effective (75%) and devoid of any appreciable toxic side effect on the treated animals; it may be used without strict diet and is also allowed in the pregnancy.

The experimental treatment of cows, suffering from fasciolosis, with intramuscular injections of CCl₄ in the mixture with paraffin or rape-seed oil (1 : 1) proved to be ineffective for the therapy of the disease in the province veterinary practice (painfulness, occurrence of pathologic changes in the muscles, etc.).

In view of the negligible efficacy, produced side effects and the necessity to keep a special diet during the administration, the above given drugs can not be regarded as those of choice.

The aim these investigations was to test the therapeutic effectiveness and safety of CoribanR applied in lambs infected experimentally with Fasciola hepatica. Post-mortem examinations showed high effectiveness of this drug, mainly in young forms of F. hepatica beginning from the third day of invasion. Hematological and biological examinations carried out during the experiment indirectly confirmed, not only the high effectiveness of CoribanR, but also, evidence that there were no side effects in the animals that were treated.
