Chemical Sympathectomy Increases Sensitivity to Ocular HSV‐1 Infection

Thoracoscopic sympathectomy increases efferent cardiac vagal activity and baroreceptor sensitivity.

OBJECTIVES Thoracoscopic sympathectomy at levels T2 or T2-T3 is a treatment for focal hyperhidrosis and facial blushing. These levels of the sympathetic trunk innervate the heart, and consequently, the procedure is reported to change the heart rate variability due to changes in efferent cardiac autonomic activity. Our objective was to investigate the effects of thoracoscopic sympathectomy on gl...

Chemical Ocular Burns - Preamble

Chemical sympathectomy alters the development of hypertension in miniature swine.

To determine if the neurotoxin 6-hydroxydopamine could be used to chemically sympathectomize neonatal miniature swine, eight newborn swine were treated with 6-hydroxydopamine beginning on the first day after birth and continuing at regular intervals for the next 6 months. Six littermates served as controls and received vehicle injections. A significant reduction in the pressor response to intra...

Chemical lumbar sympathectomy in patients with severe lower limb ischaemia.

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...

Chemical sympathectomy of the cat with 6-hydroxydopamine.

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...
