..., the mediobasal hypothalamus (MBH) and/or pituitary was excised from normally cycling female rats and perifused in an in vitro sequential double chamber perifusion system. Administration of 10 –7 M histamine caused significant release (90–170% increase, p < 0.05) of LH from the pituitary in sequence...

...Claude E. Boujon; Gilberto E. Bestetti; Marianne J. Reymond; Giovanni L. Rossi We have developed a model for combined morphological and functional in vitro studies of the isolated mediobasal hypothalamus (MBH) by considering two prerequisites: (1) the tissue must be well preserved, free...

...-pull perfusion technique to characterize and compare in vivo LHRH output from the mediobasal hypothalamus of ovariectomized middle-aged and young females during a steroid-induced LH surge. Twelve-minute perfusates were collected for a period of 6 h from middle-aged and young animals outfitted with push...

...Marco Gambacciani; Samuel S.C. Yen; Dennis D. Rasmussen The effects of oxytocin (OT) on gonadotropin-releasing hormone (GnRH) release from the adult male rat mediobasal hypothalamus and median eminence were studied in an in vitro incubation system. OT induced a dose-related (10 –13 to 10 –9 M...

...Hubertus Jarry; Monika Sprenger; Wolfgang Wuttke Push-pull cannulae were implanted into the mediobasal hypothalamus of ovariectomized (ovx) rats. After recovery animals were treated with estradiolbenzoate (E 2 B) or oil and they were perfused 3 days later. Only the E 2 B-treated animals which...

...Marco Gambacciani; Samuel S.C. Yen; Dennis D. Rasmussen The effects of corticotropin-releasing factor (CRF) on GnRH release from the adult male rat mediobasal hypothalamus (MBH) and median eminence (ME) were studied in an in vitro incubation system. CRF induced a dose-related inhibition of GnRH...

..., which couple 5-HT 1A receptors to their effector enzymes, in two subregions of the hypothalamus. The levels of Gα z protein were reduced in the mediobasal hypothalamus (containing the ventromedial and arcuate nuclei), which mainly expresses estrogen receptor-α, but not in the paraventricular...

... capillaries where GnRH is released into the portal blood. This system of GnRH neurons has been termed the septo-preoptico-tuberoinfundibular pathway [ 1, 2, 3 ]. Because the GnRH pathway courses across the mediobasal hypothalamus and throughout the arcuate nucleus (ARC), it is possible that GnRH modulates...
