[The specific features of regenerative processes of hip and shin fractures in patients with superinvasion opisthorchiasis].

Opisthorchis superinvasion retains the natural manifestations of reparative regeneration of skeletal tissues, but activates proliferation stages and increases the promoter manifestations of histogenesis. Irrespective of a surgical option, the rate of infestation, and the place of residence, reparative regeneration of shaft fractures of the shin and hip occurs significantly more rapidly in patients with superinvasion opisthorchiasis than in those without the latter. In superinvasion opisthorchiasis, bone is restituted by early callus formation and accelerated regenerate mineralization.

[Change in systemic hemodynamics after acute administration of diazepam binding inhibitor (DBI) and after autoimmunization against DBI].

Endogenous peptide DBI inhibits the activity of HABA-ergic system and that is why can be a factor of arterial hypertension development. We investigated DBI influence on cardiac index (CI), arterial pressure (AP) and heart rate (HR) in rats. I.

[Increase of seizure threshold and resistance to stress in rats after immunization against fragment of diazepam-binding inhibitor].

White rats were immunized against fragment of diazepam-binding inhibitor octadecaneuropeptide (ODN) with conjugate ODN bovine serum albumin. This rats have reduced reactions of fear and anxiety in stress model of "open field" and in conflict Vogel test; their pain sensitivity ("tail flick" test) was lowered. The number and intensity of generalized seizure reactions after injection of pentylenetetrazole were decreased.

[Effects of piracetam on pain sensitivity and levels of beta-endorphin in blood and cAMP in the cerebral cortex of rats].

It has been shown, that piracetam by i.p. injection (10, 100, 400 mg/kg) or by consumption with drinking water 10, 100, 1000 mg/kg/day during 12 days delays extinction of conditioned reflex of passive avoidance and dose-dependence elevates exploratory activity in "open field", pain sensitivity threshold reduces to 70-75%.
