[Frequency of Helicobacter pylori infection depending on morphological changes in gastric mucosa in patients over 65 years of age]

In older patients involution processes are observed. Frequency of H. pylori infection has been related of histopathological changes of gastric mucosa in patients over 65 yrs old. In 73% of analyzed patients gastritis atrophica has been documented.

[Neutrophil elastase activity in patients with ulcerative colitis]

In order to find an objective marker of disease intensity, neutrophil elastase activity was determined in patients with ulcerative colitis. The study included 41 patients with ulcerative colitis who were divided into two groups depending on tge stage of the disease on the basis of the activity index according to Maier et al. The obtained results of studies were compared a group of 18 healthy persons. The values of neutrophil elastase activity in the patients and in the control group were subjected to statistical analysis. It was found that neutrophil elastase activity in the patients with high degree of disease intensity was lower than that in the patients with low degree of disease intensity and in healthy subjects. The obtained differences were statistically significant. From the results of the study the conclusion was drawn that the neutrophil elastase activity may be an indicator of ulcerative colitis activity.

[Ulcerative colitis and pregnancy]

On the basis of literature and on the grounds of their own experience the authors presented their opinions on the coexistence of colitis ulcerosa (c.u.) and pregnancy. It was stressed that colitis ulcerosa does not decrease fertility in women whereas the taking of salazosulfapyridine diminishes fertility in men. Pregnancy should be planned during the remission period. Successive pregnancies in the same patient with coexistent c.u. should be taken individually. Classic pharmacotherapy end endoscopic diagnostics are not contraindicated in pregnancy. Past operation (e.g. partial or total colectomy) do not decrease chances of giving birth to a child. There is no evidence that artificial abortion exerts a favourable influence on the course of colitis ulcerosa. Cesarean section should be performed of obstetrical indications only. In addition, the authors emphasize the necessity of a strict monitoring of c.u. in the first trimester of pregnancy and during puerperium, as well as of a rigorous gynecological supervision in the third trimester of pregnancy.

Effect of a single dosis of 96% ethanol on rat gastric mucosa. Part II. Histoenzymological studies

The histoenzymological studies of ATPase and SDH enzymes in rats' gastric mucosa after a single 90 s administration of 96% ethanol proved considerable changes in the enzymes activity in course of injury and subsequent regeneration of mucosa.
