Sweat Evaporimeter Measurement

"1. The forearm will be cleaned with distilled water. Mineral oil will be applied to the surface of the skin after each injection.~2. intracutaneous injection of 0.2 ml of atropine~3. Stimulation and inhibition of sweating in an adjoining test area. Assessment of sweat secretion with an evaporimeter for 10 minutes after:~ 1. Intracutaneous injection of 0.1 ml carbachol for stimulation of the cholinergic sweat secretion.~ 2. intracutaneous injection of 0.2 ml atropine to Inhibit cholinergic sweat secretion~ 3. intracutaneous injection of 0.2 ml beta-cocktail (atropine isoproterenol and aminophylline) for stimulation of beta-adrenergic sweat secretion .~The procedure would take about 45 minutes."
