[Chemical anabiosis by aldehydes and protection of organs and tissues from ischemic damage].

The article is devoted to the medical biological problem that is the impact of endogenic aldehyde (methylenglucol) on tissue structures with the purpose of defending them from ischemic damage by reverse reduction of intensity of metabolic reactions, which is conditioned by reverse inhibition of the oxidation processes phosphorylation connected with reduction of losses and adenosine 5-triphosphate forming. It is ascertained that until methylenglucol in the ischemic tissue of concrete organ hasn't reduced to a certain critical level there is still an opportunity to reanimate this organ.

[Reparative osteogenesis in bone fractures under the experimental and clinical influence of exposure in the early trauma period to a UHF electrical field].

A 4-mm fracture-induced radius defect in rabbits was exposed to UHF electric field (40, 68 MHz, 20 W). The exposure promoted reparative osteogenesis though consolidation of the fragments followed the pattern of periosteal osteogenesis. Clinical data agreed with the above experimental findings.

[The essence of osteoid osteomas and osteoblastomas].

178 cases of osteoid osteomas and osteoblastomas collected during 35 years were studied morphologically and roentgenologically (angiography--28 cases). Clear-cut differences between these two lesions were revealed. The differences concerned: 1) the character of the border with the surrounding bone tissue; 2) the morphology of bone structures being chaotic in the osteoblastoma; 3) intensity of proliferation in the osteogenic tissue; 4) differences in the angiographic data.

[Destructive and reparative processes after UHF and cryo-effect on bone regeneration in dogs].

The experiment was carried out on the lower jaw of mongrel dogs. It included 36 observations on the basis of the morphological method. The aim is to study the effectiveness of the effect of cold and the combination of the UHF radiation on the proliferative reaction of cells of the lower jaw.
