[The efficacy of human NGF dipeptide mimetic on the streptozotocin-induced model of diabetes in rats].

The effect of a new dimeric dipeptide mimetic GK-2 of the loop-4 human NGF (hexamethylendiamide-bis-N-monosuccinyl-glycil-L-lysine) was investigated for the first time on the dynamics of hyperglycemia and body weight loss caused in Wistar rats by streptozotocin (45 mg/kg i.p.) Prophylactic (2 weeks before streptozotocin) daily administration combined with therapeutic (4 weeks after STZ) administration of GK-2 (0.

[Application of miniinvasive surgical plasty in the patients with umbilical hernia].

The investigation is devoted to improvement of surgical plasty in umbilical hernia. There were studied up the results of operations using classical and proposed miniinasive methods. New methods consisted of constricting suturing of umbilical ring in the hernial aperture diameter less than 2 cm and from 2 to 5 cm, using mini-accesses, establishment of the net implant, fixed with the sutures behind posterior sheets of rectal abdominal muscles.

[In vivo study of the pharmacokinetic interaction of afobazole and losartan (cytochrome CYP2C9 substrate)].

The influence of afobazole on isoenzyme CYP2C9 production in rats was studied using losartan as the marker drug. Single dose of losartan was administered orally without afobazole in a dose of 30 mg/kg and in the same single (30 mg/kg) on the background of 3- and 4-day administration of afobazole in a dose of 5, 25, 75, 100, and 125 mg/kg. At 5 mg/kg (effective dose for anxiolytic effect), afobazole did not cause any induction/inhibition effect on CYP2C9 isoenzyme.

[Neuroprotective effects of a dipeptide mimetic on the GK-2 nerve growth factor in model of permanent common carotid artery occlusion in rats].

The behavioral and biochemical effects of a new dipeptide mimetic of the GK-2 nerve growth factor (NGF) have been studied on a model of chronic cerebral ischemia induced by permanent common carotid artery occlusion in rats. It is established that subchronic intraperitoneal injections of GK-2 (0.5 mg/kg) 4 h after surgery, followed by seven more injections made every 24 h, fully prevent the death of operated animals and reduces the development of habitation deficit (open-field test) and decrease in exploratory activity (novel object examination) two weeks after surgery, as well as fully restores the viability of cerebral cortex cells and decreases the hyperexpression of HSP70 in cerebral cortex.

[The search of small molecules with antipsychotic activity on the background of neurotensin].

Tridecapeptide neurotensin (NT) is known to exert the neuroleptic-like effects in case of its intracerebral administration. The group of systemically active dipeptides , acylprolyltyrosines, was constructed on the background of NT. Methyl ester of N-caproyl-L-prolyl-L-tyrosine (Dilept) was chosen for further development.
