Glomus faciale tumors: A report of 3 cases and literature review.

Our objectives in reporting this case series are to familiarize readers with the rare occurrence of paragangliomas originating along the facial nerve and to provide a literature review. We describe 3 such cases that occurred at our tertiary care academic medical center. Two women and 1 man presented with a tumor adjacent to the vertical segment of the facial nerve.

WIN-55,212-2 and SR-141716A alter nicotine-induced changes in locomotor activity, but do not alter nicotine-evoked [3H]dopamine release.

Nicotine, the main psychoactive ingredient in tobacco, plays a key role in the development of cigarette smoking addiction. The endocannabinoid system has been demonstrated to have an important role in the motivational and reinforcing effects of drugs. The present study used behavioral and neurochemical techniques to study the interaction of cannabinoid receptors and nicotine pharmacology.

Studies of antibodies in the sera of patients who have made red cell autoantibodies.

Background: In patients in whom autoantibodies of broad specificity (panagglutinins) are present in the serum, adsorption studies are often necessary to identify alloantibodies that are simultaneously present.

Study Design And Methods: Samples from 138 patients in whom the direct antiglobulin test was positive and antibody was present in the serum were studied. When antibody identification studies before or after initial adsorption suggested the presence of an alloantibody, additional alloadsorptions were performed.
