title: Innervation and cholinesterase activity in the skin of albino and desert rats.
abstract: The distribution of nerves and cholinesterase activity in the skin of the desert and albino rats has been studied using both histological and histochemical techniques. In the desert rat, the skin was richly innervated. Specific cholinesterase was concentrated in the nervous network of the dermis and around the hair follicles, in the nerve bundles of the dermis, in perivascular nerves, in fine intra-epithelial nerves and in sensory end organs in the junctional area between the dermis and epidermis. In the albino rat, specific cholinesterase was concentrated in the sebaceous glands. The positive cholinesterase activity that was seen in the desert rat in intra-epithelial nerves, and in dermal and hair follicle networks could not be demonstrated.
