[Activity of gastric mucosal NO synthase in duodenal ulcer]. / Aktivnost' NO-sintazy slizistoi obolochki zheludka pri iazvennoi bolezni dvenadtsatiperstnoi kishki.

The paper covers the results of 32 endoscopic studies. The D. E. Korzhevsky procedure was used to determine the activity of NADP.H diaphorase, a NO-synthase marker, in gastric mucosal biopsy specimens from patients with acute and scarring peptic ulcer. A high activity of NO synthase was found in patients with acute ulcer and its inhibition was ascertained in those with scarring ulcer. The findings lead to the conclusion that NO-dependent mechanisms are involved in the pathogenesis of an ulcerative process.

Basing upon the histochemical study of SDG and NO-synthase activity in 68 biopsies taken from patients with duodenal ulcer the connection between the clinical specificity and the activity of the disease the SDG activity decreases, while that of NO-synthase increases. At the phase of cicatrization the opposite process is going on. The authors connect the phenomena under investigation with the vasodilatory and protective abilities of the nitrogen oxide.

[Nonspecific lung disease morbidity among the sailors of the Black Sea maritime steamship company]. / O zabolevaemosti nespetsificheskimi bolezniami legkikh moriakov Chernomorskogo morskogo parokhodstva.

The authors present an analysis of the general morbidity among sailors. It was established that the leading place is occupied by diseases of the respiratory organs. It is proposed to include in the system of medical choice of sailors examination of the external respiration and immune status.
