[Study of the granule-containing cells of the arteries of the base of the brain of vertebrates and humans].
Ultrastructure of chromaffin, mast and pigment cells has been studied in Liza soiuy, Rana temporaria, Testudo horsfieldi, guinea pig, cat, as well as in human fetuses at the age of 7-28 weeks of intrauterine development. Correlative connections of the vegetative neural fibres and mast cells have been revealed by means of Falck's method in guinea pigs, given noradrenaline, rausedil and histamine, and in Testudo horsfieldi, given acetylcholine. The chromaffin cells differ from the mast and pigment cells by extremely small granules. In Liza soiuy and in Rana temporaria the granule-containing cells present in all arterial membranes. It contributes to direct regulatory influence on various elements of the vascular wall. In other animals and in man these cells are situated mainly in adventitia and affect smooth arterial myocytes. The vegetative neural transmitters and the granule-containing cells make a single for regulating system.
