[Method of modelling acute transient coronary insufficiency in rats]

A special plastic lamina placed on the myocardium is suggested to protect the coronary artery and heart from gross mechanical injuries during simulation of acute transitory coronary insufficiency. The author describes a procedure for lamina manufacture and application. Squashing of the artery is accomplished by its close pressing to the inferior surface of the lamina while tightening ligature knots. The myocardium and the artery are injured insignificantly which is accounted for by the fact that all the most traumatic manipulations, such as tightening and loosening of the thread knots and cutting of ligature are performed on the protective lamina rather than on the myocardium or artery wall.
