[Surgical treatment of aortic arch malformations in infants under cardiopulmonary bypass].

Aim: To evaluate long-term results and the causes of complications in congenital obstructive pathology of the aortic arch.

Material And Methods: Retrospective study enrolled 62 patients aged 55 ± 14 days who underwent aortic arch surgery under cardiopulmonary bypass. It was compared two methods of aortic archplasty: use of xenopericardial material in group 1 and Rajasinghe's autoplastic method in group 2.

[The manifestation of synergy during simultaneous thermochemical action on yeast cells].

In order to obtain new fundamental knowledge, patterns of manifestation of synergy have been studied after simultaneous combined action of hyperthermia (47.5-60 degrees C) with anti-tumor agents (cyclophosphamide, cisplatin) on the survival of yeast cells. To calculate the efficiency of the synergistic interaction, the dependence of cell survival on the duration of exposure at separate and simultaneous action of chemical agents and hyperthermia was used.

[The study of opportunity of aqueous humor filtration increase after nondestructive laser exposure of sclera in the site of pars plana projection (experimental study)].

Increase of scleral water permeability due to formation of porous structure after exposure of pulsed periodic radiation of erbium-glass optical fiber laser with wave length 1,56 pm was demonstrated in experimental study of cadaver human eyes in vitro and eyes of experimental animals (rabbits) in vivo. Simultaneous complex laser exposure of pars plana and ciliary processes results in summation of morphological changes that provide decrease of aqueous humor secretion, uveal drainage and extension of suprachoroid space. A base for new noninvasive technology of nondestructive laser exposure in glaucoma treatment is established.
