Detection of the complex of chromatin DNase-tRNA by gel filtration

By gel filtration on Sephadex G-100, the formation of the complex of chromatin DNase-tRNA has been detected. The complex is reactivated after RNase treatment. The molecular weight of the enzyme-inhibitory complex is estimated to be 85,000.     

Therapeutic effect of the transfusion of UV-irradiated donor plasma in mechanical jaundice

The method of intravenous administration of UV-irradiated donor plasma to patients with jaundice of different genesis has been tested in the experiments on rats and used clinically in 20 patients. Biochemical and morphological studies have shown that such treatment causes stable improvement in the liver functional state.     

Changes in nerve structure on one side of the body following section of the inferior alveolar and sciatic nerves on the opposite side of the body in dogs]

The author describes changes of the lower alveolar and ischiadic nerves on the non-operated side after cutting such nerves on the opposite side of dogs, as well as changes in the organs innervated by them. The observed dystrophic changes in the nerve fibres on the non-operated side turn into more severe and non-reversible changes due to abnormal stimulation. Changes of masticatory organs appearing after cutting the lower alveolar nerve have bilateral manifestations being more pronounced on the same side especially in the case of a simultaneous dissection of the lower alveolar artery. These investigations contribute to possible interpretation of cases of symmetrical caries, development of dento-maxillary deformations on both sides.     

Effect of the limbic cortex on regional lymph and blood flow in dogs]

Electrical stimulation of the anterior limbic area of the cortex in dogs resulted in increase of the lymph flow from the intestinal lymph duct, in enlargement of the mesenteric lymph nodes, in a fall of arterial pressure in the cranial mesenteric artery, and in decrease of the blood-stream from the homonymous vein and in the tone of the mesenteric veins. Constriction of the mesenteric veins and increase in the intestinal lymph-stream are considered to be a compensatory reaction to restore the arterial pressure to the initial level.     

Effect of acid metabolites on the osteoinductive activity of the bone matrix

The osteoinductive activity of bone matrix demineralized in acid metabolites of glycolysis and Krebs cycle have been studied in rats. The highest osteoinductive effect was reached during the demineralization in oxaloacetic acid, the lowest one--in the malic acid. The regulatory role of glycolysis metabolites and Krebs Cycle in posttraumatic osteogenesis is under discussion.
