[Changes in the degree of oxygenation of gastric mucosa before and after the operation of creating a small stomach in patients with the extreme degree of alimentary-constitutional obesity].

The authors examined 131 patients with alimentary-constitutional obesity of Degrees III-IV before and after operation for "small stomach" formation. All patients underwent pre- and post-operative endoscopy of the esophagus, stomach and duodenum. The level of gastric mucosa oxygenation was measured in 50 patients before and in various periods after surgery.

[Possibilities of laser-endoscopic spectrum analysis in laryngology].

This paper discusses the potential application of a laser-endoscopic spectral analyzer in fibrolaryngoscopy for early detection of neoplasms (luminescence combined with spectrophotometry) as well as for examination of the laryngeal mucosa by measuring oxygenation and blood flow in microcirculation with the aid of spectrophotometry. The results of examinations of 35 patients have shown that the laser-endoscopic spectral analyzer can be used to perform premorphological rapid tests in cancer diagnosis and to assess the efficacy of therapeutic methods.
