BACKGROUND The possible contribution of endothelin-1, a potent endothelium-derived vasoconstrictor peptide, to neurohumoral compensation for hemodynamic stress was examined in nine normal volunteers and six patients with severe congestive heart failu

We studied the interaction of endothelin and endothelium-derived relaxing factor (EDRF) in human saphenous veins and internal mammary arteries using isolated ring preparations. Endothelin was a more potent constrictor of human internal mammary arteri

As reported earlier, d-amphetamine (0.25–1.0 mg/kg) produced a dose-dependent depression of play fighting as indexed by the frequency of pins and the total duration of play fighting. Amphetamine reduced both the frequency of play bouts and the dura

According to the opioid hypothesis of social attachment opiate receptor blockade should increase the need for social contact. Yet naloxone reduces play fighting [11], a major form of social interaction in young rats. This observation might be reconci

To determine the influence on play fighting of inputs to the brain that arise in or course through the olfactory bulbs juvenile male and female rats were bilaterally bulbectomized at 23 or 24 days of age. The frequency of play fighting and play initi

The effects of medial preoptic area (MPOA), anterior hypothalamic (AH) and ventromedial hypothalamic (VMH) lesions on play fighting were studied in juvenile rats that were housed and observed in heterosexual groups of 6–8 animals. Overall males eng

Moderate doses of amphetamine and methylphenidate profoundly depress play fighting in juvenile rats. To test the idea that this behavioral effect was dependent on the release of catecholamines (CAs) we administered haloperidol (0.05–0.8 mg/kg), chl
