[Effects of ultra-dispersed piezoceramics Pb powders on staff's health status]. / Vliianie ul'tradispersnykh poroshkov p'ezokeramiki na sostoianie zdorov'ia personala.

The ultradispersed piezoceramic powder containing lead oxides, zirconium, titanium, bismuth, cadmium, manganese, strontium, and chromium was tested for its effect on the health status of the staff serving pilot industrial units producing the powder. There was a significant increase in the incidence of digestive disease, a tendency for respiratory and osteomuscular diseases to increase. It is concluded that it is necessary to use individual means of the protection and prophylaxis of the observed diseases.

Morphological characteristics of peripheral blood erythrocytes in rats subjected to chronic inhalation of ultradispersed piezoelectric ceramic powder.

In albino rats subjected to chronic inhalation of ultradispersed piezoceramic powder, scanning electron microscopy revealed changes in membrane surface of peripheral blood erythrocytes manifested as decreased number of diskocytes and increased number of transitional, prehemolytic, and degenerating forms. These parameters returned to normal 1 month after termination of inhalations.

[Correction of energy metabolism disorders in rat liver in tetrachloromethane poisoning using sapropel lipids]. / Korrektsiia narushenii énergeticheskogo metabolizma pecheni krys pri otravlenii tetrakhlormetanom s pomoshch'iu lipidov sapropelia.

Energy metabolism was studied in poisoned rat liver tissue after application of sapropel lipid extracts and its fractions. Total extract and its polar fraction affected distinctly the energy metabolism and ultrastructure of hepatocytes. The restoring influence of sapropel lipids appears to occur due to both their chemical composition and adaptogenic effect on intracellular reparation.

[The correction of disorders in the exocrine function of the liver by using sapropel lipids in tetrachloromethane poisoning (experimental research)]. / Korrektsiia narushenii vneshnesekretornoi funktsii pecheni s pomoshch'iu lipidov sapropelia pri otravlenii tetrakhlormetanom (éksperimental'noe issledovanie).

Reparative and bioregulatory properties of total lipids extracted from sapropel were studied in experimental chemical toxic hepatitis. The extract exhibited a combined antioxidant and bioregulatory effect on hepatic lesions. This finding permitted the total lipid sapropel extract to be suggested as a bioactive corrector of chemical hepatic intoxication.

[Comparative evaluation of the biological activity of the lipid fractions of silt mud]. / Sravnitel'naia otsenka biologicheskoi aktivnosti lipidnykh fraktsii ilovoi griazi.

The biological activity of polar and non-polar lipid fractions obtained from silt mud has been studied. It has been shown in rats with experimental exudative peritonitis that phonophoresis of the polar fraction has pronounced anti-inflammatory, stimulant and resolving effects. The non-polar hexane-soluble fraction has been found to be biologically inactive despite the presence of carotene.
