[Cytomorphometric diagnosis of dysplasias during dyshormonal and hyperplastic processes in the mammary gland].

A hundred and twenty-nine cytograms of benign tumors of the breast with different degrees of its dysplasia were morphometrically analyzed, by using a "MECOS-Ts" set for digital microscopy. The informative differentially diagnostic morphometric signs of nuclei were identified in mild, moderate, and severe epithelial dysplasias of the breast. The derived quantitative decision rules may reduce the error of a differential diagnosis of severe dysplasia by 2-3.5 times, as compared with a visual microscopy-based diagnosis.

[Automated procedures for microscopic analyses of blood smears: medical testing a MECOS-Ts2 complex].

The paper presents the results of medical tests of a group of computer-aided procedures for microscopic analysis by means of a MECOS-Ts2 complex (ZAO "MECOS", Russia), which have been conducted at the Republican Children's Clinical Hospital, the Research Institute of Emergency Pediatric Surgery and Traumatology, and Moscow City Clinical Hospital No. 23. Computer-aided procedures for calculating the differential count and for analyzing the morphology of red blood cells were tested on blood smears from a total of 443 patients and donors, computer-aided calculation of the count of reticulocytes was tested on 318 smears. The tests were carried out under the US standard NCCLS-H20A. Manual microscopy (443 smears) and flow blood analysis on a Coulter GEN*S (125 smears) were used as reference methods. The quality of collection of samples and laboriousness were additionally assessed. The certified MECOS-Ts2 subsystems were additionally used as reference tools. The tests indicated the advantage of computer-aided MECOS-Tsl2 complex microscopy over manual microscopy.

[Automated cytophotomorphometric tests of blood smears in general clinical studies and population screening].

Automation of routine operations of photomorphometry of blood smears realized in the MEKOS-C cytoanalyzer helped create a new level of using a set of cytological tests, such as assessment of the leukocyte and erythrocyte formulae and of the histogram of hemoglobin distribution in red cells, estimation of leukocyte subtypes, assessment of the characteristics of the nucleolar system and the nucleoli-forming sites. Automated complex analysis of an increase in the measured characteristics of red and white blood cells impossible in common microscopy and flow cytoanalyzers appreciably improves the sensitivity and accuracy of tests and extends the range of their application. Low cost of analysis of a blood smear permits the use of MEKOS-C not only in clinical studies, but even in overall prophylactic screenings of the population.

[Analysis of erythrocytes in the MEKOS-C system].

Quantitative cytofluorimetric analysis of red cells by the MEKOS-C device provides complete information about peripheral blood erythrocytes, which cannot be obtained by other methods and equipment. An analysis is cheap and sensitive, this recommending it for practical hematology, toxicology, and narcology. The MEKOS-C device permits the preclinical diagnosis of a number of diseases and monitoring their treatment. The device is cheap and available for therapeutic and diagnostic institutions of all levels.

[A comparative morphometric analysis of cytograms of invasive ductal and invasive lobular breast cancer].

The most informative for differential diagnosis parameters (surface and nucleus polarization) were determined on the basis of morphometric analysis of 42 cytograms of invasive duct cancer (IDC) and 39 cytograms of invasive lobular breast cancer (ILC) using the computer analyzer MEKOC-C. Combination of these two parameters allowed the authors to elaborate a decisive rule for differential diagnosis of these two cancers (the mistake is reduced to 8.6%). The analysis of 8 informative morphometric nuclear parameters has shown that in ILC the nuclei are more monomorphic, less in square and perimeter, nucleoli are less numerous than in IDC. The study gives objective criteria for preoperative differential cytological diagnosis between IDC and ILC.

[An automated microscopy system MECOS-Ts2 and its trial use for blood and bone-marrow smear analysis].

Disadvantages of conventional procedures for testing of medical automated microscopy systems are considered. A testing procedure based on step-by-step testing of the system units is suggested. The procedure makes use of remote data analysis through communication lines. The structure of MECOS-Ts2 automated microscopy system and the procedure for its testing are considered.

[Automated MECOS-Ts2 microscopy complex in pathologoanatomic practice].

Computer-aided and information systems of a MECOS-Ts2 microscopy complex designed to transmit a representative image of a specimen along communication lines are considered. The above systems allow the use of the complex: 1) in on-line and off-line modes to provide tele-medical services (cytology, histology, etc.); moreover, the requirements for channel traffic may be decreased over and over again as compared to the routine on-line videomicroscopy mode; 2) for telemedical tests of specialized local automatic procedures of microscopical analysis (analysis of smears of blood and bone-marrow smears, parasitological analysis, etc.); 3) for collection of a representative electronic archive of the "virtual" specimens of rare nosological entities, which have been obtained in different medical institutions, w hich will provide valid statistical assessments of diagnostic decisions; 4) for remote accompaniment of MECOS-Ts2 complexes by the manufacture (update of versions, training, quality control of sample preparation, collection of commission statistics); 5) for training and certification of remote laboratory staff. The functions considered cannot be implemented in analyzers of other types, in flow analyzers, in particular.
