Pharmacological responsiveness of sweat glands in anxious patients and healthy volunteers
S Maple, CM Bradshaw and E Szabadi
The responsiveness of eccrine sweat glands to local intradermal injections
of carbachol and phenylephrine was studied in six male and six female
healthy volunteers and six female patients suffering from anxiety neurosis,
using a plastic paint impression method. Carbachol evoked consistently
greater responses than phenylephrine. The response to carbachol attained a
peak approximately two minutes after injection, whereas the response to
phenylephrine attained a peak within fifteen seconds of the injection.
Males showed greater responsiveness to both drugs than females, this being
reflected in significantly higher maxima of the dose-response curves for
the males. The anxious females showed a higher level of spontaneous sweat
gland activity and greater responsiveness to both drugs (reflected in
higher maxima of the dose- response curves) than the normal females.
