    Abstract:
    Estradiol conjugated to bovine serum albumin at position 6(E-6-BSA) released oxytocin (OT) from homogenates of the medial preoptic area and medial hypothalamus (MPOA-MH) within minutes of its superfusion. Using a superfusion system in which synaptosome-containing homogenates were layered onto acrodiscs maintained at 37 degrees C, we have found that E-6-BSA (100 ng/microliters) superfusions significantly elevated OT release within minutes. In contrast, superfusion of the same concentration of BSA or progesterone-3-BSA (P-3-BSA) had no effect on OT release. While superfusing homogenates with augmented levels of K+ had no effect on OT release itself, superfusing E-6-BSA with these concentrations of K+ consistently increased OT release. This is the first demonstration that E-6-BSA increases OT release in a nucleus-free medium.
