METHOD FOR DIAGNOSING THE CASES OF HEPATIC PATHOLOGIES

FIELD: medicine. ^ SUBSTANCE: method involves studying blood serum, processing obtained data and setting disease diagnosis. The study is carried out by preparing dried blood serum sample as suspension in Vaseline oil and doing the infrared spectroscopy analysis in the bandwidth of 120-1000 cm-1 and determining absorption strip peak heights having maximum at 1180; 1165; 1160; 1150; 1130; 1070; 1025 cm-1 and then calculating the following two ratio groups, the first of which is ratio of peak height with maximum at 1165 cm-1 to 1150 cm-1; 1160 cm-1 to 1130 cm-1; 1070 cm-1; 1025 cm-1. The second group has ratio peak having maximum at 1165 cm-1 to 1160 cm-1; 1180 cm-1 to 1130 cm-1; 1065 cm-1; 1070 cm-1. The obtained three-dimensional distribution of the first group is projected to frontal plane for calculating two-dimensional coordinates and comparing to flat reference diagnostic images of hepatic pathologies and to a normal reference diagnostic image represented as flat polygons which boundaries are given by the following values. The norm is represented by X(-2.3;2.0;4.0;4.0) and Y(1.6;0.8;0.8;1.6), respectively. Oncology is represented by X(1.7;1.7;0.0;0.0) and Y(1.9;1.25; 1.25;1.9). Hepatites are represented by X(1.9;2.2;1.8;1.4 and 1.9;1.8;4.0) and Y(1.9;1.9; 0.5;0.5 and 08;0.5;0.8). Cirrhosis is represented by X(1.9;2.6;1.4) and Y(1.6;0.8;0.4). Diseases are differentiated by interpreting point position within particular area. Three-dimensional distribution of the second group is projected to frontal plane and compared to diagnosis images of pathology and norm. Coordinate values of the second group are as follows: norm - X(1.8;2.9;2.5;1.5), Y(2.7;2.0;1.2;1.6); oncological cases - X(0.27;0.67;0.63), Y(0.27;0.67;0.3); hepatitis - X(1.5;2.5;2.4;1.2), Y(1.6;1.2;0.2;0.9); cirrhosis - X(1.1;0.9;0.9). Final diagnosis of pathology is set when particular data values belong to the corresponding pathology zone in both cases. ^ EFFECT: high accuracy of diagnosis.
