The long-term administration of nitric oxide synthesis inhibitors induces arterial hypertension accompanied by left ventricular hypertrophy and myocardial ischemic lesions. Because the enhancement of sympathetic drive has been implicated in these phenomena, the current study was performed to determine the potency of β-adrenoceptor agonists and musc...

Blood pressure and blood volume are closely regulated by the interrelated actions of the sympathetic nervous system (SNS) and the renin-angiotensin-aldosterone system (RAAS). Reflex vasoconstriction caused by parallel SNS and RAAS activation is modulated by two interactive negative feedback systems called baroreflex. The aortic-carotid baroreflex s...
The present study was performed to determine the effects of central administration of leptin on food intake and sympathetic nervous system activity in a nonrodent species, the rhesus monkey. Peripheral administration of leptin at doses (1 and 3 microg/kg, s.c.) that produced increments of circulating leptin concentrations within a physiological ran...

Pheochromocytoma is a catecholamine-producing tumor of the sympathetic nervous system. Signs and symptoms are generally related to catecholamine excess; these include hypertension, sweating, palpitatione, headaches, and anxiety attacks. Abdominal imaging and 24-h urine collection for catecholamines are usually be sufficient for diagnosis. Catechola...

We report a 3-year, 5-month-old boy with an adrenocortical carcinoma. These tumours are rare and highly malignant in childhood. In most cases they are functional, secreting adrenocortical hormones. In this case there was a misleading coexistence with a second abdominal neoplasm, which was a ganglioneuroma; this is a rare benign tumour arising from ...
Over the last few years, neurologists have been showing increasing interest in the study of the sympathetic skin response (SSR). In the present report we describe a simple method that permitted us to determine a wide variation of SSR in response to different stimuli such as respiration, deglutition, blinking, skeletal movements, biting, auditory or...
