The article considers a study of morphological features of neurons in thoracic spinal ganglion in 10-, 20-, 30-, 60- and 90-day-old rats under chemical deafferentation and desympathisation. In capsaicin-treated and guanethidin-treated animals, the growth and section area of neurons has been oppressed and decreased, as well as neurons differentiation intensity has been reduced for all animal classes. Thus in desympathised rats the effect of guanethidin on аfferent neurons is expressed in the greater degree, than in deafferentated rats under capsaicin influence.
