[Evaluation of antimutagenic properties of powdered malt and polymalt extracts with the use of micronucleus test].

There were performed studies of the occurrence of cells with pathologies in the buccal epithelium of volunteers who consume drinks based on mixtures ofpowdered malt and polymalt extracts of buckwheat, peas, corn and barley. There was shown their impact on the stability of the genetic material of examined cases. There was established activation of apoptosis, which leads to the elimination of cells with cytogenetic deteriorations. Poliymalt extracts possess protective properties, contribute to the suppression ofprocesses offormation of cells with genetic disorders (micronuclei (from 4.38 ± 0.67 %%, up to 2.53 ± 0.39 %% after intake), protrusions (from 1,98 ± 0,42 %%, up 0,85 ± 0,25 %% after intake), incisures (from 3.34 ± 0.44 %%, up 2.17 ± 0.35 %% after intake), two cores (from 1.63 ± 0.26 %%, up 0.65 ± 0.21 %% after intake) and rid the body of aberrant cells, as evidenced by the increase in the number of cells with karyolysis (up to 5.98 ± 0,91 %%, up 9.55 ± 1.74 %% after intake), karyopyknosis (from 10.71 ± 0.90 %%, up to 11.97 ± 0.85 %% after intake) and perinuclear vacuoles (from 9.24 ± 1.63 %%, up to 12.94 ± 2.57 %% after intake). In women, anti-mutagenic effects ofpolymalt extracts are more pronounced than in men. Antimutagenic effects of extracts can be explained by the properties of contained in them B vitamins and sulfur-containing amino acids (cysteine and methionine).

[IMPLEMENTATION OF MEASURES FOR OCCUPATIONAL HYGIENE AT ENTERPRISES OF BREWING INDUSTRY].

In the paper there are considered the legal basics of the occupational hygiene of brewing production: acts, bylaws and normative legal acts. There are characterized types of supervision and control (state, departmental, public) implementing the abidance of the sanitary legislation at the enterprises of the brewing industry. There are presented sanitary and hygienic requirements to the enterprises of the brewing industry. There are designated measures of occupational hygiene of brewing production: a sink, cleaning--removal of various pollutions, and also disinfection--process of the decline in quantity of microorganisms to safe level. There are considered some characteristics of pollutions which are subject to removal at various stages ofproduction of beer and stages of sanitary processing of brewing systems according to chemical properties of substances.

[Mistakes and complications appearing during treatment of chronic pulpitis of the deciduos teeth in children].

On the basis of clinical data dentists' mistakes and complication appearing in treatment of chronic pulpitis of the deciduous teeth in children in private dental clinics were investigated. Causes of their occurrence were revealed and ways of their prophylaxis were suggested.

[Plasma levels of biogenic amines in patients with various forms of the alcohol abstinence syndrome]. / Soderzhanie biogennykh aminov v plazme krovi u bol'nykh s razlichnymi formami alkogol'nogo abstinentnogo sindroma.

Norepinephrine (NE), dopamine (DA) and serotonin (5-HT) blood plasma levels were measured in 40 alcoholic patients (2nd stage) during overt manifestations of the alcohol abstinence syndrome (AAS). Twenty-five healthy individuals served as controls. The patients were divided into four groups according to the structure of their AAS-related psychopathology and the progress of the disease. In the fast-progressive group with autonomic disorders prevalent in the AAS structure, the excitability, NE and DA levels were elevated. In the group with prevalent asthenic-neurotic and affective disorders, the 5-HT levels were lower than controls. The group with fast-progressive course of the disease and schizoaffective disorders had both the 5-HT and NE levels lowered. The authors discuss the possible impact of the results on perfectioning of the differential AAS therapies.
