title: [Action of 13-cis-retinoic acid and aromatic retinoid on several cutaneous parameters in hyperseborrheic rats].
abstract: Castrated rats submitted to androgenic stimulation present hyperseborrhea with an increase in foamy cells associated with an increase in cutaneous lipids and a change in the number of epidermal cell layers. 13-cis-retinoic acid and aromatic retinoid (Ro 10-9359) were given orally during 17 days (10 mg/kg) to castrated rats which had received a testosterone implant. Cyproterone acetate was chosen as the antiandrogenic drug; it was given at doses of 10 mg/kg i.m. once every other day. As opposed to cyproterone acetate, the two substances studied had no effect on the seminal vesicle and ventral prostate. 13-cis-retinoic acid and retinoic aromatic acid increased the total number of epidermal layers: In the case of 13-cis-retinoic acid, the increase involves especially the nonnucleated cell layers, whereas with retinoid aromatic acid it involves the nucleated cell layer. The number of sebaceous glands is not changed by either products, on the other hand, the number of foamy cells is considerably decreased and the weight of cutaneous lipids is decreased as well.
