[The histochemical evidence of the cholinesterase in the integument by means of the copper ferro cyanide methode (author's transl)].

With the aid of the Ferrocyanidmethod from KARNOVSKI und ROOTS ChE-positiv structures in the skin of various laboratory animals and of man were located. Specific cholinesterase is found in verves, around apocrine sweat glands and around eccrine sweat glands of some species. In the stratum basale of the epidermis from the rat you can demonstrate a high concentration of acetylcholinesterase. Unspecific cholinesterase is detectable in nerves, in the blood vessels, in the lumen of apocrine sweat glands and sebaceous glands.
