The objective of this study was to determine the contribution of renal nerves to the enhanced afferent arteriolar reactivity observed in angiotensin II (Ang II)-induced hypertension. Uninephrectomized Sprague-Dawley rats were divided into four groups: sham rats, renal-denervated rats, Ang II-infused (at 40 ng/min for 13 days) rats, and Ang(More)
Radio-frequency and anodal electrolytic lesions of the paraventricular nucleus (PVN) were found to produce equal and dramatic increases in body weight in female rats. Neither of the groups with lesions had significantly elevated plasma insulin levels during a period of food restriction, but individual values varied greatly. Both groups displayed marked(More)
The drug Ecstasy (3,4-methylenedioxymethamphetamine (MDMA)) is one of several hallucinogenic amphetamine derivatives reported to be serotonergic neurotoxins. The following is a description of a new high-pressure liquid chromatographic (HPLC) analytical method for the analysis of MDMA, 3,4-methylenedioxyamphetamine (MDA) and(More)
Ketorolac is a nonsteroidal anti-inflammatory drug (NSAID) that is indicated for the short-term management of moderately severe, acute pain, that causes analgesia equivalent to that caused by morphine. It has been shown experimentally that the analgesia produced by ketorolac in mice can be diminished by pretreatment with naloxone. This observation suggests(More)
Female rats were subjected to radio-frequency or anodal electrolytic lesions of the ventromedial hypothalamus (VMH) when 28 days old. Blood samples for determination of basal plasma insulin and glucose levels were taken on postoperative day 30 (Experiment 1) and on day 10 (Experiment 2). Body weight and daily food intake of rats with either type of lesion(More)
