Electron microscopic and histochemical investigations of the atretic oocyte of Perca fluviatilis L. (Teleostei).

abstract：:By means of a preembedding immuno-electron-microscopic technique, a large number of nerve endings containing a substance related to human growth hormone-releasing factor (hGRF) have been demonstrated in the paraventricular nucleus of the guinea pig. They made synaptic contacts primarily with dendritic shafts: 80% of t...
