[Morphogenetic features of reparative regeneration of acetate gastric ulcer under chronic exposure to pesticide--copper sulphate].

Using morphologic, histochemical, histoenzymatic methods, the authors studied morphogenesis of acetate gastric ulcer in 40 rats subjected to chronic enteral intake of copper-containing pesticide-- copper sulphate. Structural and metabolic basis for perverted regeneration of mucosa near the ulcer under continuous enteral exposure to toxic factor, dose dependence in chronization of acute gastric ulcer were established for the first time.

[Morphogenesis of acetate-induced gastric ulcer upon chronic exposure to the pesticide hexachlorocyclohexane].

Morphological, histochemical, and histoenzymatic studies were employed to study the morphogenetic features of acetate-induced gastric ulcer in 40 rats during chronic enteral administration of the organic chlorine pesticide hexachlorocyclohexane. The authors first established the structural and metabolic bases of mucosal regeneration defects in the region of an ulcer upon chronic enteral exposure to the toxic agent and the dose dependence of the chronic nature of acute gastric ulcer.

[Expert system of choosing lower limb (thigh) prosthesis and diagnosis of the quality of prosthetics (II)].

The authors review an expert system (ES) of diagnosing the prosthetics quality, elucidate problems of the ES functioning within the framework of the general ES. Special attention is paid to the description of the knowledge and datum surface, to the algorithms of direct and reverse illegible logical data output in taking decisions as to defects of the patient's prosthesis in accordance with the signs observable. The work of the ES is demonstrated with special reference to concrete cases.

[An expert system for choosing prostheses for the lower extremities (hip) and assessing the quality of the prosthesis. I].

The authors describe the structure, characteristic features and experience gained with the employment of an expert system for the choice of hip prostheses (in cases of unilateral amputation) and assessment of the prosthetics quality. Word the requirements for hardware and software, present functional subsystems corresponding to certain interrelated stages of prosthetics. A variant has been devised of an appropriate training expert system with a profound representation of intelligence in an object area.
