Environmental exposure of small children to polycyclic aromatic hydrocarbons.

Objectives: The aim of the study was to assess the intake (by various routes of exposure) of polycyclic aromatic hydrocarbons (PAH) by children living in a Czech city, and its effect on excretion of 1-hydroxypyrene (1-OHP) in summer and winter periods.

Methods: Four groups of children (3-6 years old) were chosen: (1) two groups from a kindergarten situated in the city center with a higher traffic density ("polluted" area); (2) two groups from a kindergarten situated in a green zone of the same city ("non-polluted" area). Food consumption was recorded in all children and PAH intake from foodstuffs was estimated.

Assessment of multipathway exposure of small children to PAH.

The aim of study was to assess the uptake of polycyclic aromatic hydrocarbons (PAH) by children living in a city and its effect on 1-hydroxypyrene (1-OHP) excretion. Two groups of children (n=11 and 13; 3-6 years old) were chosen: (1) a group from a kindergarten situated near a road with a high traffic density ('polluted' area); (2) a group from a kindergarten situated in a green zone ('non polluted' area). Food consumption was recorded in all children and PAH uptake from foodstuffs was estimated.

[Levels of CK MB mass in patients with acute myocardial infarct treatedwith fibrinolysis. Comparison with levels of CK, CKMB, CKMB mass and troponin T in the diagnosis of coronary ischemia].

In a group of 26 patients with AIM the CKMB value was raised above the discrimination level already on admission--on average 2.7 +/- 1.4 hours after development of ischaemic pain--in 46% patients.

Long-term monitoring of the immune reactivity of stainless steel welders.

The immune reactivity of stainless steel welders (n = 22-53) was evaluated in a three year's study. The results (phagocytic activity, cellular and humoral immunity) were statistically compared with those in control group of non-exposed persons from the same plant (n = 14-23) and with long-term laboratory reference values (LRV) (n = 14-311). In welders several changes were found when compared to the LRV: in humoral response there were higher prealbumin, lysozyme, circulating immune complexes and lower IgG.

[Systematic Long-term Screening of Scolioses.].

The authors implemented in a defined region for a period of 14 years screening of scolioses in children, primary screening using Adams' test and secondary screening using a scoliometer. They selected as criterion for detection 5 degrees of asymmetry of the back, corresponding to 17 degrees according to Cobb on X-ray pictures. In three growth stages a total of 603 children with scoliosis were detected, incl.
