The cellular mechanism of action of the cannabimimetic drugs is examined using cultured cells. In membranes from N18TG2 neuroblastoma cells and the neuroblastoma X glioma hybrid cells, NG108-15, the psychoactive cannabinoid drugs and their nantradol analogs could inhibit adenylate cyclase activity. This response was not observed in either the soluble(More)
The push-pull cannula was used to examine the release of endogenous norepinephrine (NE) from the paraventricular hypothalamic nucleus (PVH) of unanesthetized freely moving 7- to 10- and 12- to 14-wk-old Sprague-Dawley (SD), Wistar-Kyoto (WKY), and spontaneously hypertensive (SHR) rats. Basal NE release, K+ (56 mM) stimulation-induced NE release, and NE(More)
Previous studies from this laboratory demonstrated that there was enhanced basal and evoked (K+ depolarization) overflow of endogenous norepinephrine (NE) into the perfusate of a push-pull cannula placed in the paraventricular nucleus of the hypothalamus (PVH) of conscious freely moving spontaneously hypertensive rat (SHR) compared with Wistar-Kyoto (WKY)(More)
The relationship between age and central noradrenergic neuronal activity of the paraventricular hypothalamic nucleus (PVH) was examined in 7- to 10-, 12- to 14-, and 30- to 36-wk-old Sprague-Dawley (SD), Wistar-Kyoto (WKY), and spontaneously hypertensive rats (SHR). As an index of noradrenergic activity, endogenous norepinephrine (NE) overflow was assessed(More)
The arachidonic acid metabolites are recognized as important biochemical mediators of inflammation in a wide variety of disease processes. Also the ability to change prostaglandin formation by inhibition of prostaglandin synthetase activity with aspirin and other nonsteroidal anti-inflammatory agents is important in the treatment of many diseases with an(More)
