Local sympathetic denervation by surgical sympathectomy is used in the treatment of lower limb ulcers and ischemia, but the restoration of cutaneous sympathetic nerve functions is less clear. This study aims to explore the recovery of cutaneous sympathetic functions after bilateral L2-4 sympathectomy. The skin temperature of the left feet, using a point monitoring thermometer, increased intraop...

Over a 13 year period, 544 chemical lumbar sympathetic blocks with phenol in 489 patients were performed by the author with the aid of X-ray image intensification. There was objective and subjective improvement in the signs and symptoms of limb ischaemia in 72%, judged by relief of rest pain, improvement in skin blood flow or healing of ischaemic ulcers. Of patients treated in the years 1990-19...

The aim of the present study is to investigate the mechanisms of suppression of splenic natural killer (NK) cytotoxicity caused by cold stress, using 6-hydroxydopamine (6-OHDA) as chemical sympathectomy. The NK activity was measured by (51)chromium release assay. Central sympathectomy with intracerebroventricular (i.c.v.) injection of 6-OHDA reduced significantly the elevation of plasma cortico...

Background and Objective: Sleep deprivation (SD) is caused by a host of reasons and has numerous consequences on cardiac system. In this study, we aimed to assess the preconditioning effects of acute SD on ischemia (IS)-induced ventricular arrhythmias in isolated rat hearts. Materials and Methods: Male Wistar rats randomly were placed into the four groups: IS-group, acute SD group, control grou...

OBJECTIVES To investigate the role of primary afferents, sympathetic postganglionic efferents and descending systems on the central control of peripheral inflammation. METHODS Acute inflammation was induced by intra-articular injection of kaolin and carrageenan into the knee joint cavity of the rat. Before the induction of the arthritis, a unilateral dorsal rhizotomy, a chemical (phentolamine...

Sympathetic nervous system (SNS)-mediated peripheral vasoconstriction plays a key role in initial maintenance of blood pressure during rapid-onset asphyxia in the mammalian fetus, but it is attenuated after the first few minutes. It is unclear whether the SNS response is sustained during the brief, but frequently repeated, episodes of asphyxia characteristic of labor. In the present study, 14 f...

HAEUSLER, G., W. HAEFELY AND H. THOENEN: Chemical sympathectomy of the cat with 6-hydroxydopamine. J. Pharmacol. Exp. Then. 170: 50-61, 1969. Cats were given 6-hydroxydopamine (6-Oll-DA; 2,4,5-trihydnoxyphenethylamine) i.v. according to a schedule which had previously been found to produce a selective and almost complete destruction of peripheral adnenergic nerve terminals. After varying interv...

AIMS To determine whether there were temporal or seasonal patterns in the occurrence of chemical incidents reported to the West Midlands Chemical Incident Surveillance System, UK. METHODS A retrospective analysis of reports maintained on a computerised database was carried out for information received from January 1997 to December 2001. RESULTS Annual numbers of events increased significant...
