The implementation of factor analysis for the evaluation of selected blood parameter changes induced by hyperbaric exposure.

This paper discusses the application of factor analysis when used to compare selected blood parameter (a three-parameter smear, hematocrit, C3c, C4, IgG, IgA, IgM, CRP, fibrinogen and the level of factor XII) properties, just before, and after exposure to pressure changes, and 24-hours after the completion of decompression. To-date the most popular method of statistical analysis was based only on investigation of the significance of the separated individual parameters. This factor analysis that has not been applied previously in the analysis of such problems, enabled the neutral hierarchic evaluation of the significant parameter changes within their chosen range, and mutual relationships. It seems that the application of this method is purposeful and it can be an objective tool for evaluating the significance of changes in blood constituency induced by pressure.

[A proposal of the use of selected medical databases and net services as an element of the early epidemiological recognition]. / Propozycja wykorzystania wybranych medycznych baz danych i serwisów sieciowych jako elementu wczesnego rozpoznania epidemiologicznego.

In the paper the actual system of collection and distribution of epidemiological data as well as the threats of national and society security, resulting from delayed reaction to bioterroristic attack are described. Furthermore, the authors' opinion on importance of rapid collection and instant distribution of medical data, potentially useful during the early epidemiological recognition, including the practical use of selected medical databases and net services is presented.

Changes of selected morphotic parameters and blood plasma proteins in blood of divers after a single short-time operational heliox exposure.

In the Polish Navy, deep-water dives, performed for the needs of the maritime industry, are conducted using our own national technology and trimix as a breathing medium. In this paper are presented the results obtained during a short-time deep-water diving test using the principles of US Navy technology, combined with the use of diving equipment type AF-2 and heliox-type breathing mixture in the open circuit. In the performed examinations changes in clinical parameters were assessed viz.: blood morphology, hematocrit level, concentration of C3c, C4, IgG, IgA, IgM, CRP, concentration of fibrinogen and factor XII level, obtained 30 minutes prior to commencement, immediately after completion, and 24 hours after termination of the exposure. The results thus generated were subjected to a preliminary analysis by the description of trends observed. It was revealed that the diving technology employed did not generate substantial changes in the examined parameters of blood in divers, and the increase of neutrophils, blood platelets and fibrinogen concentration in the blood plasma immediately after diving is of temporary character, being a typical reaction observed during diving.
