Erythrocyte and microcirculatory functions during artificial circulation

Erythrocyte morphology, their aggregation ability and microcirculatory pattern in the mesentery of the small intestine have been studied stepwise on 12 dogs under artificial blood circulation. It has been shown that erythrocyte lesions followed by pathological aggregation play an important role in the pathogenesis of microcirculatory failure. Prolonged artificial circulation provokes structural reorganization in erythrocytes, thus affecting both blood rheology and gas exchange.     

Genetic analysis of mutations affecting the synthesis of somatic O-antigen of Vibrio cholerae

The mutations oagM and oagR affecting the synthesis of somatic O-antigen have been localized on the chromosome of Vibrio cholerae El Jor and classic biotypes by conjugational crosses between different donor and recipient strains. The mutations are localized in the vicinity of the arg marker in both classic and El Tor biotypes of Vibrio cholerae.     

Tolerance to standard and non-ionic contrast media in patients with ischemic heart disease and stable angina pectoris during coronary angiography]

Angiography of the coronary arteries with iohexol was carried out in 45 coronary patients with stable angina pectoris and that with diatrizoate in another group of 45 similar patients. Iohexol was tolerated better that diatrizoate. Physiological and hemodynamic side effects of iohexol were less marked than those of diatrizoate.
