1. Alterations in vascular reactivity were assessed in isolated artificially perfused kidneys from stroke-prone spontaneously hypertensive (spSH) rats at different stages of hypertension and after neonatal sympathectomy with 6-hydroxydopamine (6-OHDA). 2. During the pre-hypertensive stage, and the early and chronic stages of hypertension, the responses to noradrenaline, vasopressin, serotonin a...
BACKGROUND Facial hyperhidrosis is a disease that may lead patients to serious emotional disturbances. Video-assisted thoracic sympathectomy provides excellent resolution of facial hyperhidrosis, but is associated with certain complications. The most frequent and important complication is compensatory hyperhidrosis. Especially in patients who have undergone resection of the second thoracic gang...
We evaluated the endothelial function of patients with Buerger disease using peripheral arterial tonometry test, and examined the factors that are significantly correlated with the endothelial dysfunction in these patients. We performed the peripheral arterial tonometry test in 22 patients with Buerger disease. We recorded the patients' characteristics, including ankle brachial pressure index a...
UNLABELLED In certain patients with neuropathic pain, the pain is dependent on activity in the sympathetic nervous system. To investigate whether the spared nerve injury model (SNI) produced by injury to the tibial and common peroneal nerves and leaving the sural nerve intact is a model for sympathetically maintained pain, we measured the effects of surgical sympathectomy on the resulting mecha...
CGRP and substance P (SP) are produced in dorsal root ganglia (DRG) sensory neurons and modulate vascular tone. Sympathetic and sensory nerves compete for NGF, a potent stimulator of CGRP and SP, and it has been suggested that sympathetic hyperinnervation in spontaneously hypertensive rats may reduce the availability of NGF to sensory nerves, thus reducing CGRP and SP. The purpose of this study...
OBJECT Video-assisted thoracoscopic sympathectomy is a safe, effective, and minimally invasive procedure for primary hyperhidrosis. This study aims to evaluate long-term results and patients' quality of life and investigate potential variables responsible for compensatory sweating after one-stage bilateral single-port thoracoscopic sympathectomy. METHODS Between 2005 and 2011, 260 consecutive...
Data from 90 lumbar sympathectomies were reviewed to assess the role of a distal thigh/arm Doppler systolic index (DTAI) and of external magnetic flowmeter (MCBF) measurements for predicting patient outcome following lumbar sympathectomy. The presenting symptoms included impending gangrene, gangrene, rest pain, nonhealing ulcers, and disabling claudication. Of the 90 cases, clinical improvement...
The contribution of the sympathetic innervation to the postnatal development of cardiac contractility remains unclear. In this study, the postnatal maturation of cardiac contractility was compared in control rats and rats after chemical sympathectomy. The chemical sympathectomy was induced by administration of 6-hydroxydopamine to newborn rats. At days 20, 40 and 60 of postnatal life, the contr...
OBJECTIVE To compare two surgical techniques (denervation levels) for sympathectomy using video-assisted thoracoscopy to treat palmar hyperhidrosis in the long-term. METHODS From May 2003 to June 2006, 60 patients with palmar hyperhidrosis were prospectively randomized for video-assisted thoracoscopic sympathectomy at the T2 or T3 ganglion level. They were followed for a mean of 20 months and...
The hepatoportal region is important for glucose sensing; however, the relationship between the hepatoportal glucose-sensing system and the postprandial rapid phase of the insulin response has been unclear. We examined whether a rapid-phase insulin response to low amounts of intraportal glucose infusion would occur, compared that with the response to intrajugular glucose infusion in conscious r...
