title: [Hyperplasia of the adrenergic nerve fibers of the vessels and myocardium in rats with spontaneous hypertension].
abstract: Adrenergic innervation of the myocardium vessels was morphometrically studied in 4-, 8-, 12- and 20-week-old spontaneously hypertensive rats (SHR). The increase of cardiac adrenergic nerves was found in the early period of persistent hypertension (in 12-week-old SHR). In the vessels this increase was more pronounced and started earlier, at prehypertensive stage (in 4-week-old SHR). The data obtained confirm the hyperplasia of the terminal part of the sympathetic nervous system, this reflecting the increased sympathetic influence on cardiovascular system in hypertension.
