Bioimpidance analysis is a possible method of diagnostics of tumors and intact tissues. The purpose of the study To investigate biophysical characteristics of RS-1 tumor and surrounding tissues. Materials and methods An experimental investigation was performed on 10 Wistar rats with transplanted RS-1 tumor (signetring cell carcinoma). Invasive bioimpedancemetry was produced by a device “BIM-II” for measuring the electrical impedance of biological tissues (Patent of Russian Federation № 2366360). After bioimpedancemetry histological examination was performed. Results and their discussion Differences between impedance of tumor and intact tissue (p&lt;0,05) were revealed. Histological examination confirmed that the transplanted tumor was the signet-ring cell carcinoma (RS-1). There were not found any malignant cells in tissues surrounding the tumor during histological examination. Conclusion An algorithm based on bioimpedance analysis for the verification of the tumor and intact tissue was developed</p></abstract><trans-abstract xml:lang="ru"><p>Актуальность Важным этапом хирургического лечения злокачественных опухолей является их удаление в пределах нор- мальных тканей. Возможным методом диагностики опухоли от интактных тканей является биоимпедансометрия. Цель исследования Провести оценку биофизических параметров опухолевой ткани РС-1 относительно окружающих тка- ней. Материалы и методы Исследование проведено на 10 крысах линии Вистар массой 180-220 г, которым в ходе экспери- мента прививали опухоль РС-1 (перстневидно-клеточный рак). Инвазивную биоимпедансометрию опухоли и прилегающих тканей проводили с помощью аппарата BIM-II, разработанного в ООО «Центр трансфера инновационных технологий», г. Смоленск. Во всех зонах, где измеряли электрический импеданс, проводилось гистологическое исследование на предмет наличия опухолевых клеток. Результаты и их обсуждение Выявлено, что значения биоимпедансометрии опухоли отличались (p&lt;0,05) от показателей импеданса нормальной ткани. Морфологический анализ подтвердил, что перевитая опухоль являлась перстневидно-кле- точным раком (РС-1). При гистологическом исследовании окружающих опухоль тканей опухолевых клеток обнаружено не было. Выводы На основе биоимпедансного анализа разработана методика верификации опухоли от интактных тканей.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Experiment</kwd><kwd>tumor</kwd><kwd>intact tissue</kwd><kwd>bioimpedance analysis.</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>эксперимент</kwd><kwd>опухоль</kwd><kwd>интактная ткань</kwd><kwd>биоимпедансный анализ.</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>1.
