[The healing of a large intestine anastomosis].

Three types of colonic anastomosis were experimentally studied on 19 mongrel dogs. Best results were obtained when using precise three-row sutures with the restoration of the intestinal mucosa which was confirmed by histological investigation of the zone of colonic anastomosis. Clinical observations during operation on the colon in 58 patients when using the two-row and precise sutures are in keeping with experimental findings and show advantages of the precision anastomosis.

[Cardiovascular effects of digoxin in acute myocardial ischemia].

A study was made of the effect of digoxin on the systemic hemodynamics and collateral circulation in acute occlusion of the dog left coronary artery. Digoxin (0.01 mg/kg) made the collateral blood inflow to the ischemic zone increase intensely and for a long time, raised the cardiac output due to an increase in the stroke volume, lowered the total peripheral vascular resistance in the presence of high heart contractility and work.
