[Acid production and factors of its regulation in patients with different results of ulcer surgical treatment].

Features of regulation of gastric acid production in 82 patients with favorable and unfavorable results of duodenal ulcers (DU) surgical treatment were studied. Current radioimmunoassays were used for assessment of hormonal and acid production function of operated stomach. It is demonstrated that an increase in gastrointestinal and pancreatic hormones secretion in postvagotomic syndromes depends on postoperative disorders degree and terms after gastric surgery that may be regarded as hyperactivity of regulatory systems.

[Experimental study of photodynamic effect on bacterial wound microflora].

Staphylococcus aureus, S. epidermidis, Pseudomonas aeruginosa, Escherichia coli, Proteus mirabilis cultures have been isolated from wound secretions and identified.
