title: [The role of mastocytes in the development of the adrenergic innervation of the iris].
abstract: During the development of the primary adrenerg-plexus in the rat iris presence of mastocytes showing intensive fluorescence can be observed using the method of Falck. After the formation of the primary plexus this phenomenon disappears. By electron microscopy in the early period of the postnatal life authors demonstrated the presence of mastocytes closely related to developing neurofibrils and Schwann-cells. In these mastocytes signs of degranulation were to be observed. On the base of the latter finding one can assume, that substances deliberated from the granules may play a part in the regulation of the development of innervation.
