Lymphatic microvessels in the myocardium: artifact or objective reality?

Most of the current information on the lymphatic flow bed of the heart was obtained by the method of interstitial injection of various dyes, including the masses of Gerot. Low information content and numerous artifacts do not allow us to consider the data obtained by this method on lymphatic microvessels of myocardium reliable. The purpose of the work is to confirm or refute the data on the presence of lymphatic microvessels in the myocardium, using various methods for their detection. The vessels of the microvascular flow bed of the myocardium of intact experimental animals, rats (n = 7), cats (n = 3), rabbits (n = 3) was detected by the methods of Grant and Ranvier-Goyer in modification II. Markov. As a control, a universal method for the impregnation of argyrophilic structures was used. The data obtained give unambiguously reason to believe that there are no lymphatic microvessels in the myocardium of mammals.
