An attempt was made to correlate the physiological or the dimethylbenz(a)anthracene (DMBA)-enhanced serum prolactin (PRL) surge, which occurs in the afternoon of proestrus in female Sprague-Dawley (SD) rats, with physiological or pathological changes in two biochemical estimates of the tuberoinfundibular dopaminergic (TIDA) neuron activity. Dopamine (DA)(More)
The distribution of the messenger RNA (mRNA) coding for neprilysin (EC has been studied by in situ hybridization in the adult rat brain. A markedly heterogenous distribution among various brain regions was found. A strong signal was observed in the glomerular layer of the olfactory bulb, the olfactory tubercle, the caudate putamen, the habenular,(More)
This paper further substantiates the physiological role of beta-endorphin (beta-END) in the control of the cyclic LH secretion and provides new data on the interactions between 17 beta-estradiol (17 beta-E2) and beta-END at both the hypothalamic and pituitary levels. At the hypothalamic level, during the estrous cycle in rats, beta-END concentrations were(More)
