Do cocaine and SKF-82958 potentiate brain stimulation reward in Swiss-Webster mice?
Cocaine and SKF-82958 each potentiate the rewarding effects of lateral hypothalamic brain stimulation in Swiss-Webster mice, implying that these drugs have rewarding effects of their own. The reward-facilitating effects of low doses of cocaine and SKF-82958 are additive (or synergistic). These data suggest that SKF-82958 may decrease cocaine-seeking behavior by mechanisms related to reward rather than aversion.
Local corticosteroid injection of the retrocalcaneal bursa may help the symptoms of retrocalcanear bursitis, but pose a risk of Achilles tendon rupture. This risk-benefit has to be taken into account when corticosteroid injections are prescribed to professional and high-level athletes.
