Keywords: 5-aminolevulinic acid, Aminolevulinic acid, Bioelectrical impedance, Diagnostic efficiency, Electrical measurement, Fluorescence mapping, Impedance measurement, Polarization coefficients

Abstract: We studied gender differences in gastric tumor in rats using original model of gastric adenocarcinoma and photodiagnostics with delta-aminolevulinic acid, and impedance measurements of the stomach, liver and red blood cells in rats of both genders. Highly heterogeneous gastric adenocarcinoma in rats of both genders was induced by means of a prolonged exposure to social and chemical stresses. Exogenous fluorescence mapping using 5-aminolevulinic acid / protoporphyrin IX was performed on the developed tumors, and the suspicious areas were investigated and compared with the surrounding intact tissues by electrical bio-impedancemetry techniques. The histological data revealed significant gender differences in as the number of male rats with neoplasia was higher by a factor of 1.5. Exogenous fluorescence maps were detected in gastric cancerous areas, but no gender correlation was observed. Significant gender differences were revealed when bioelectrical impedance..
