[Detection of Determinants of Functional Aortic Regurgitation in Patients With Ascending Aorta Aneurism by Transesophagea1 Echocardioscopy].

We used transesophageal echocardioscopy for the study of effects of linear parameters of the aortic root and characteristics of its subvalvular space (area of subvalvular space of the aortic root during diastole and aortic cusps coaptation height) on severity of aortic regurgitation in patients with aneurism of ascending aorta and anatomically unchanged aortic valve (AV), i.e. so-called functional aortic regurgitation (FAR). We found that appearance of FAR was associated with coefficient of disproportion sinotubular ridge/fibrous annulus of AV > 1.67, aortic cusps coaptation height > 0.47 cm and area of subvalvular space of the aortic root >0.49 cm2. Respective values > 2.23, > 1.07 cm, 0.49 cm2 evidenced for the presence of pronounced FAR.

[Evaluation of a patient cytochemical status using nonparametric statistical methods].

The paper shows limitations of the traditional indices used to evaluate a patient's chemical status and describes methods for assessment of its uniformity, by using nonparametric chi 2 test, identifying patient subgroups, and comparing a few groups. A new procedure is proposed to present cytochemical findings.

[Absolute and relative errors of individual determination of cytochemical indices in clinical practice].

The study assesses absolute and relative errors in the calculation of cytochemical indices in a precise patient. At present, the semiquantitative index (the mean cytochemical coefficient (MCC) after G. Astaldi and L. Verg) is widely used to evaluate the cytochemical activity of leukocytes. At the same time other indices, such as differentiating cytochemical coefficient (DCC) after I. G. Bondarenko, occasionally find application. Analysis of the results of simulation of an array containing 500 leukograms has demonstrated that the individual relative detection error for MCC ranges from 13 to 21% and that for DCC 20 to 51%. The results of the study enable an adequate estimation of the ways of expressing the cytochemical findings, which are proposed by different authors.

Effect of sodium hypochlorite and UV irradiation of the blood on fluid and electrolyte balance, metabolism of lipids and proteins, and state of cell plasma membranes during experimental bile peritonitis.

We compared the normalizing effects of various methods of hemocorrection on homeostasis in animals with bile peritonitis. Combined treatment with hypochlorite and UV irradiation produced a potent membrane-stabilizing effect and increased adaptability of erythropoiesis.

Water-electrolyte balance, lipid and protein metabolism, and state of cell plasma membranes during experimental bile peritonitis.

The development of experimental bile peritonitis was accompanied by a variety of homeostatic changes. The disease is characterized by a specific clinical and laboratory syndrome.

The outfit of an automated workplace of the biochemical practitioner at the clinical diagnosis laboratory of an emergency hospital is described in the paper. The advantages and disadvantages are analyzed and potentialities of improving the basic outfit are defined.

[Use of multi-dimensional statistic analysis for integral evaluation of treatment quality in patients with suppurative-inflammatory diseases of maxillofacial region]. / Primenenie mnogomernogo statisticheskogo analiza dlia integral'noi otsenki kachestva lecheniia bol'nykh s gnoino-vospalitel'nymi zabolevaniiami cheliustno-litsevoi oblasti.

Possibilities of modern methods of maths statistics for comparative evaluation of efficacy of different methods of treatment of patients with suppurative-inflammatory diseases of maxillo-facial region were analyzed and an integral index of treatment efficacy was suggested. Application of the integral index of treatment efficacy showed that intravenous injection of sodium hypochlorite and autohemotherapy with oxidized blood led to the closest apposition of cluster center of these patients to the cluster center of healthy persons. It testifies to greater efficacy of such treatment of the disease in comparison to the other methods.

[End point and kinetics. Pluses and minuses]. / Konechnaia tochka i kinetika. Pliusy i minusy.

There are results of laboratory quality control in determination of transminase activity by two methods--by end point and by kinetic method. Based on the performed dispersion analysis, a conclusion was made that despite the correspondence of both methods to the order # 45 of RF Ministry of Health, the determination of ALT and AST activity by end point does not register the moderately pronounced increase in the level of these enzymes. This point makes it impossible to use the data obtained in the analysis of transminase activity by end point to verify and monitor syndrome of endogenous intoxication.

[Diagnostic significance of evaluating erythrocyte membrane permeability as an intoxication syndrome criterion]. / Diagnosticheskaia tsennost' otsenki pronitsaemosti membran éritrotsitov v kachestve kriteriia intoksikatsionnogo sindroma.

Twenty-five patients with pyoinflammatory maxillofacial diseases treated in an inpatient setting in the Regional Dentistry Clinic of Krasnodar and 8 healthy volunteers were examined. After opening and draining of the purulent focus the patients were divided into 2 groups. Group 1 consisted of 21 patients treated by intravenous 0.04% sodium hypochlorite (SHC) and intravenous infusions of SHC-oxidized autoblood for 2-3 days. Group 2 (6 pts) was treated by intravenous infusions of SHC-oxidized autoblood for 6 days. The criteria of intoxication were erythrocyte resistance tests in hypotonic sodium chloride and at different concentrations of urea in isotonic medium. A new method for evaluating erythrogram deviations from reference values is proposed, which helps adequately assess the severity of intoxication.
