[Bordetella pertussis infections in the district of Bielsko and the city Bielsko-Biala].

Introduction: In the recent years there has been an increase in the incidence of infectious diseases that may be caused by the lack of guardians' consent to carry out immunization among children. In Poland in 2012 there was an increase in the incidence of pertussis 180% higher than in 2011. Occurring symptoms of pertussis can occur with varying intensity depending on the patient's age, his general health and the number of taken doses of vaccination against pertussis.

[Analysis of possible interaction between lead and calcium in gallstones from active and passive smoking and no smoking women].

The problem of interaction between lead and calcium in gallstones from active and passive smoking and no smoking women living in southern Poland is presented in the work. The subject of the research were gallstones, gained intraoperatively from 93 women (24 active smoking, 18 passive smoking, 51 no smoking women). The content of lead and calcium was determined using atomic emission spectroscopy with inductive couple plasma (ICP-AES).

[Application of PCA (Principal Components Analysis) for the estimation of smoking effect on the occurrence of trace elements in women's gallstones].

The PCA (Principal Components Analysis) was used to estimation of the role of smoking in the changes of elements contents in gallstones. The concentration of given elements were determined by ICP-AES method. It was stated that smoking regardless of sex, influence on the occurrence of elements in hydroxyapatites of gallstones, in particular it concerns changes of As, Pb, Zn, Se, Ti contents.
