Newly occurring stenocardia: the clinical picture, diagnosis, treatment and prognosis

The article analyses the results of treatment of 77 patients with primarily emerged stenocardia. Three variants of clinical course of illness were distinguished: primarily emerged stenocardia at the state of exertion, primarily emerged progressive stenocardia at the state of exertion, primarily emerged stenocardia at rest state. As for primarily emerged stenocardia at the state of exertion, the changes at the final part of QRS complex were disclosed in 56% of patients, and abnormalities in the mobility of the left ventricle walls in 32%. The contractive function of left ventricle was unchanged. The myocardial infarction developed in 8% of patients in the course of one month, and in 4% in the course of one year. Stenocardia attacks disappeared in 16% of patients. As for primarily emerged progressive stenocardia, the ECG changes were marked in 74% of cases. The whole sphygmic fraction in 65% of patients was 55% lower. The myocardial infarction developed in 12% of patients in the course of one month and in 10.7% in more remote period. 52% of patients with the primarily emerged stenocardia at rest had ECG changes. In ECG daily monitoring 33% of patients had characteristic changes of coronary artery spasm. Myocardial infarction occurred in 8% of patients in the course of the first year. Stenocardia attacks disappeared in 25% of patients.     

Glycine and alanine synthesis enzymes in the tissues of the silkworm during its development

The activity of enzymes of glycine and alanine synthesis (glutamate-pyruvate aminotransferase, aspartate-beta-decarboxylase, threonine aldolase, serine hydroxymethyltransferase, alanine-glyoxylate aminotransferase, aspartate aminotransferase) is studied in haemolymph, fat body, fibroin and sericine divisions of silk gland of silkworm Bombyx mori at terminal period of larva development. Alanine-glyoxylate aminotransferase activity in fibroin division of silk gland (34,6 mu mole of glycine/mg of protein/min-10(-3)), alanine aminotransferase--in sericine division (36,0 mu mole of alanine/mg of protein/min-10(-3)) aspartate aminotransferase 27,3 mu mole of glutamic acid/mg of protein/min-10(-3)) and alanine aminotransferase (35,8 mu mole of alanine/mg of protein/min-10(-3)) on fat body. The ratio of alanine-glyoxylate aminotransferase/glutamate-pyruvate aminotransferase activities in posterior division of silk gland is near to glycine/alanine ratio in silk fibroin. The character of the enzymes activity in silkworm tissues correlates with the silk formation rate.     

Influence of the Design Features of a Magnetron Sputtering Deposition System on the Electrical and Optical Properties of Indium—Tin Oxide Films

Semiconductors - The influence of the relative position of a magnetron and substrate on the electrical and optical properties of a forming indium–tin oxide (ITO) layer is shown. The reasons...     

Effect of preliminary chronic low-dose gamma-irradiation on the compensatory potentialities of the hematopoietic system

Rat experiments indicate that chronic gamma-preirradiation in a dose of 90.0 rads (dose rate 3.0 rad/day) inhibits development of adaptive reactions of hematopoietic system throughout resistance of general adaptation syndrome in emotional stress.
