Evaluation of the effect of cold atmospheric plasma on oxygenases' activities for application in water treatment technologies.

Plasma-based technologies take an increasing place in the new conceptions of wastewater management as a promising tool for the treatment of persistent organic pollutants with low biodegradability. Plasma major advantage is the synergy of diverse active components with high oxidative action and additional benefits as disinfection of treated water. But the bactericidal effect of plasma can influence the treatment effectiveness when this technology is used in combination with biological methods for the removal of pollutants.

[The connective tissue changes in patients with acute poisonings by organophosphate pesticides].

The changes in the derma, selected as a representative of highly organized connective tissue, were studied by 8 types of staining and histochemical reactions in 896 biopsies of macroscopically unchanged skin from the gluteal region of 56 patients with acute phospho-organic pesticide intoxication between the 2d and 15th day after the intoxication. 272 biopsies from 17 healthy persons and the literature data, describing the normal structure of the skin, served as controls. Nonspecific changes affecting mainly the elastic and collagen components, in some cases parallel to the severity of the intoxication, were found.

Alterations in macroscopically intact skin of children with juvenile rheumatoid arthritis.

Punch biopsies of macroscopic-intact skin were performed on 75 children with rheumatoid arthritis, aged 4--14 years. There was no significant correlation between the morphologic alterations and the sex and age of the children or the duration of the disease, but there was a positive relationship with the degree of activity of the rheumatoid process. It appears that punch biopsy of the skin in children with juvenile rheumatoid arthritis can facilitate determination of alterations of the connective tissue if the data obtained are regularly correlated with clinical and laboratory findings.
