[Type UUKM-4d carbonic carbon and porous titanium in plastic repair of bone defects: experimental studies].

The experimental laboratory of the Saint Petersburg Research Institute of Pharmacology studied the potentialities of replacing bony defects and cavities by type UUKM-4d high-porous carbonic carbon. It was found that in orthotopic implantation, the more intensively bony osseous tissue was grown into the pores of an implant made of carbonic carbon, the more prolonged a postsurgical interval was; just at month 1 after orthotopic implantation, carbonic carbon implant was tightly fixed in the bony bed. Porous titanium is also fixed in the osseous defect without producing negative reactions of a patient's osseous tissue.

[The effect of intravascular helium-neon laser blood irradiation on the state of the compensatory processes in the acute period of hemorrhagic shock and after resuscitation].

The effect of low-intensity intravascular laser blood irradiation on morphofunctional characteristics of erythrocytes and circulation parameters has been studied experimentally on 22 adult inbred anesthetized dogs of both sexes 9 to 23 kg of weight during a 2-hour hemorrhagic shock and in the first hours after resuscitation. It has been established that the use of intravascular laser blood irradiation during 45 min of hemorrhagic shock stabilizes erythrocyte membranes and improves myocardial function. Hyperdynamic and hyperperfusion syndromes were significantly more pronounced in the postresuscitation period in animals treated by intravascular laser blood irradiation than in the control.
