[The growth of axons in the periphery after a decrease in the quantity of nerve cells in sympathetic ganglia].
The amount of cells in stellate ganglia of rat was decreased by chemical sympathectomy to 30% of the normal amount. At the age of two months sympathectomized rats have no pressor reflexes to asphyxia and femoral nerve stimulation. These responses are restored at the age of four months. The electron-microscopic and fluorescence-microscopic data show that the growth of axons in the remaining adrenergic neurons of sympathectomized animals takes place at the age between two and four months.
