ABSTRACT
The sampling of study included 172 patients with ischemic heart disease: 146 with acute coronary syndrome, including myocardial infarction (88 patients) and unstable stenocardia (58 patients); 26 patients with stable stenocardia functional class II-III. At the 1-3 day of hospitalization blood was taken of cubital vein. The mixed unstimulated saliva was selected. In both of them conte of calcium, sodium and potassium was tested (mmol/l). Under acute coronary syndrome, in blood content of calcium was 2. sodium--139.6 and potassium--4.5 i.e. the content was lower than in case of stable stenocardia (2.4; 139.8; 4.7 correspondingl In saliva under acute coronary syndrome higher content of calcium (1.05) and potassium (34.66) and lower content of sodiu (25.42) was established in comparison with stable stenocardia (0.81; 33.7; 28.08 correspondingly). The distribution coefficien (blood/saliva) of calcium, sodium and potassium were higher under myocardium infarction than under unstable stenocardia at uncomplicated course of acute coronary syndrome.

The situation of stress affects various organs and systems that results in development of functional disorders and/or somatic diseases. As a result, different noninvasive, including salivary, techniques of diagnostic of stress conditions are in the process of development. The dynamics of acoustic indicator of saliva is studied during the period of passing the exams. The relationship of indicator with levels of potassium, sodium, glucose and protein of saliva was analyzed. The sampling consisted of 102 students of 5 and 6 academic years of medical university. To detect the acoustic indicator of saliva acoustic analyzer AKBa-01- "BIOM" was applied. The level of potassium and sodium in saliva was detected using method of flame photometry. The level of glucose in saliva was detected by glucose oxydase technique using analyzer "EXAN-G". The protein in saliva was detected by biuretic technique. The correlation between acoustic indicator of saliva and analyzed indicators of saliva was established.

A new method is suggested for determining the concentration of whole protein and the distribution of protein fractions in blood serum by means of an ultrasound device. The acoustic method is based on measuring the proliferation rate and absorption of the ultrasound signal in the examined serum. The findings of the method were compared with those obtained by routine tools in examining both blood sera of patients and controls. A high correlation factor was registered for the biuret method in the determination of the concentration of whole protein (R = 0.95; p < 0.05). It was demonstrated as possible to use the discussed method as a screening tool in evaluating the distribution of protein fractions. The examination findings are generated by the instrument as in the electrophoretic examination. The method is simple in use. No reagents are needed.

Reactive anxiety of patients was evaluated at clinical stages of orthodontic treatment with polymeric crowns. Antistress therapy essentially decreased the number of patients with high reactive anxiety. Measures to control fear are obligatory before tooth preparation and impression making. At the rest stages it is hardly necessary to focus the dentist's and patient's attention at these measures.

An original design of a microdenture insert is suggested, as are methods of preparing it to restore the frontal teeth after an injury not involving the pulp. The insert consists of two elements permitting disposition of the parapulpar pins at an almost right angle, providing a reliable fixation of the insert on the tooth. Clinical follow-up of 25 patients with 27 inserts for up to 3 years demonstrated the efficacy of such treatment.

The electric characteristics were lowered or absent in 87 patients wearing removable metal-based dentures. The explanation is as follows: in patients with plastic plate dentures and permanent metal prostheses in the oral cavity the electric charges pass between the prostheses via the saliva and oral tissues; in patients with metal-based plate dentures the charges pass along the metal basis, which fact is due to high electric conductivity of metal. Therefore in patients with plastic removable dentures the electric charges have a more detrimental effect on the oral tissues.
