[Comparative analysis of calcium accumulation in tissues of the brain and the liver in alimentary hypercholesteremia].

Some mechanisms of changing calcium content in brain and liver at alimentary hypercholesteremia were studied. Dynamics of calcium accumulation in tissues of the organs under exploration has proved its contribution to an adaptive reaction of the organism at alimentary stress and reflected peculiarities of its different stages. Similar and simultaneous dynamic changes in calcium accumulation in both organs (liver and brain) seem to be induced by stereotypical pathogenic mechanisms.

[State of the hepatobiliary system and intestines in elderly patients with concurrent digestive pathology].

Common aspects have been revealed of structural and functional disorders of the biliary tract and intestine in elderly patients with digestive pathology. We recommend that lipotropic drugs, choleretics, cholekinetics, antioxidants and eubiotics be used in the treatment of the above patients.

[Characteristics of the autonomic nervous system tests during group psychotherapy of patients with opioid dependence at the stage of induction of remission].

The time-course of changes in vegetative tests was studied in 47 men suffering from stage II opium dependence. The patients' age ranged from 18 to 28 years, with the dependence standing amounting to 1-10 years. Use was made of cardiointervalography to define the vegetative tone, as well as of the vagal and adrenaline tests to explore vegetative responsiveness.

[Structural and regenerative features of the mucosa of the upper portions of the digestive tract in chronic gastritis and peptic ulcer].

For the elucidation of the morphological features of the mucous membrane of the upper parts of the alimentary tract and its capacity for regeneration in chronic gastritis and peptic ulcer 212 patients were examined and among them in 81 gastroesophageal reflux was established. Histological, morphometric, and autoradiographic studies showed morphological changes in the mucous membrane of the esophagus, stomach and duodenum to differ in frequency and pattern in patients with chronic gastritis and peptic ulcer. The presence of the accompanying gastroesophageal reflux in the patients examined caused pathological changes in the esophageal mucosa which were more marked in duodenal ulcer.
