Correlations between the pharmacokinetics and dynamics of pharmacological effects of bromantane

It is shown that there is a mathematical correlation between an integral characteristic of activity of the organism (the capacity for work), electrophysiological indexes of functioning of the brain structures, and the concentration of a novel derivative of 2-aminoadamantane, bromantane, in the brain. The nature of the correlation between integral characteristics of the organism studied on different levels is found to change depending on the time elapsed from the administration of the preparation and on its concentration in the blood or target tissue.

Determination of subpopulations of T- and B-lymphocytes in human blood using an immunofluorescence method

The immunofluorescent technique for assaying T- and B-lymphocyte subpopulations, using monoclonal (OCT3, OCT4, OCT8) and monospecific antibodies is described. The results of immunocompetent cell determinations in normal subjects and in patients are presented. A conclusion is made that use of universal immunofluorescent method for assays of the lymphocyte subpopulations widens the possibilities of diagnosis of immunodeficiency states.     

The effect of naloxone on the preoperative gastric volume and pH

The effect of 4 mg oral naloxone on preoperative gastric volume and pH of gastric aspirate was studied in a double-blind, randomized study. Twenty patients received 10 ml of naloxone (4 mg) mixed with 10 ml of orange juice, and 20 patients received 10 ml of isotonic saline mixed with 10 ml of orange juice, 2 h before surgery. Gastric content was obtained immediately after intubation of the trachea. No significant difference in gastric volume and pH of gastric aspirate was found between the two groups. It is concluded that naloxone does not affect gastric emptying and gastric acid secretion to a degree great enough to protect against aspiration of gastric contents into the lungs.     

The late examination results in children with pylorospasm and dyskinesia of the proximal sections of the small intestine]

The article analyses the late-term results of examination of 46 children with neurogenous dyskinesias of the gastrointestinal tract which were recognised in infancy for the first time. The author believes that the functional, motor-evacuation, and sphincter disorders of the proximal parts of the digestive tube lead to the development of organic noninfectious diseases of the gastroduodenal system.
