[Stereologic method of determining the volumetric density of the arterial bed of the myocardium in histologic sections].
The volumetric density of the intramyocardial arteries proved to be equal to the sum of their volumetric densities obtained by the planimetric measurements on three interperpendicular histological sections. To avoid systematic errors only the vessels in which the ratio of the short (D) and long (L) diameters of the sections was not below (see article) greater than or equal to 0.707 should be subjected to planimetry. Examples of estimation of the volumetric density of human intramyocardial arteries are given. The volumetric density of the intramyocardial arteries was not equal in different parts of the myocardium.
