چکیده

Apomorphine hydrochloride is used to treat refractory motor fluctuations in advanced Parkinson’s disease. Delivery by infusion is associated with the formation of hard subcutaneous nodules, which may be painful, limit available infusion sites, and interfere with absorption of the drug. Diagnostic ultrasound was used to image affected tissue in 12 people experiencing apomorphine nodule formations. It revealed significant departures from normality in dermal and subcutaneous tissue, including a variety of nodule appearances, dermal thickening and diffuse changes consistent with inflammatory reactions. Sonographic appearances differed markedly between individuals, but no clear correlation between severity of tissue changes, patient demographics and apomorphine dose was observed. Diagnostic ultrasound may be useful as a non-invasive method of assessing subcutaneous nodule formation, to measure changes in affected tissue over time and after treatment.

Dopaminergic control of male sex behavior in rats: effects of an intracerebrally-infused agonist.

Systemically-administered dopaminergic drugs have been found to facilitate sexual behavior of men and male rats. The present experiments investigated the localization within the brain of dopaminergic effects on copulation of male rats. Apomorphine, a dopamine agonist, was microinfused into the medial preoptic area, caudate-putamen, nucleus accumbens, lateral septum and lateral ventricle. The lo...

Repeated administration of the dopaminergic agonist apomorphine: development of apomorphine aggressiveness and changes in the interaction between dopamine D(2) receptors and G-proteins.

The repeated administration of dopamine receptor agonists produces a progressive increase in the acute behavioral effects of these drugs, known as behavioral sensitization. These includes the development of impulsive aggressive behavior after repeated small doses of apomorphine. The aim of this investigation was to study the behavioral specificity of the apomorphine-induced aggressiveness model...
