excision or interruption of some portion of the sympathetic nervous pathway. The operation produces temporary vasodilation leading to improved nutrition of the part supplied by the vessel. It is done in cases of partial arterial obstruction with resultant trophic changes distally.

chemical sympathectomy the interruption of the transmission of impulses through a sympathetic nerve by chemical agents.

Previous studies also showed that chemical sympathectomy with 6-OHDA can delay reepithelialization in cutaneous wounds [12, 14].

[14] demonstrated that chemical sympathectomy led to reduced MC migration during cutaneous wound healing in rats.

Sympathetic Denervation Accelerates Wound Contraction but Inhibits Reepithelialization and Pericyte Proliferation in Diabetic Mice

(2001) demonstrated that chemical sympathectomy with 6-OHDA improves survival in mice infected with Listeria monocytogenes, with augmented production of IFN-g, IL-1b, IL-2, IL-4 and IL-6; conversely, noradrenaline inhibited their secretion, but no change was observed in IL-4.

After 7 days of inoculation, rats developed yellowish abscesses with well-delimited borders (arrow) (a); reduction of abscesses size (arrow) was observed when trophozoites inoculated rats were treated with vehicle (b); however, chemical sympathectomy with 6-OHDA induces size diminution of the abscess (arrow) (c).

A significant decrease on macrophages after chemical sympathectomy was observed.
