Estrogen modulation of mu-opioid receptor-stimulated [35S]-GTP-gamma-S binding in female rat brain visualized by in vitro autoradiography.

abstract：:Changes in antidiuretic substance (i.e., vasopressin) release from the cut pituitary stalk and the intact pituitary gland were observed during electrical stimulation of amygdala medial nucleus. Electrical pulses of 4 or 36 cycles per second (cps) were used and in both cases the same energy (about 2.160 nanowatt second...
