[Laparoscopic-assisted method of surgical treatment of perforated gastric and duodenal ulcer].

Conversion (laparoscopic-assisted) method of surgical treatment of perforated gastric and duodenal ulcer was used at 103 patients. This method combines minilaparotomy with videolaparoscopy. Mean duration of surgery was 53 min, mean hospital stay - 6 bed-days.

[Ethologic study of the sequelae of prenatal exposure to psychotropic agents].

The consequences of the use of pharmacological agents during pregnancy and delivery can manifest themselves not only in the form of morphological deformities of the fetus but also in the behavioral disturbances at the later age. The experiments on laboratory animals open wide possibilities for detecting the psychotropic agents with a potential ability of disturbing the offspring behavior. These properties were demonstrated for narcotic analgesics, ethanol, some tranquillizers and other drugs.

[Effect of opiate receptor agonists and antagonists on maternal aggression in rats].

The behavioral effects of opiate agonists and antagonists were studied on the female aggression model. Mu-agonist buprenorphine more selectively decreased maternal aggression than kappa-agonist tifluadom. Kappa-agonists (bremazocine, tifluadom) increased passive defence in lactating female rats.
