Pharmacological studies on retinoic acid in Wistar and in atrichos rats

Retinoic acid produces some changes in the skin which could be interpreted as a mechanism of action: release of acid hydrolases and phosphatases, inflammatory reactions, increase in lipid synthesis and transport as an energy dependent phenomenon, increase in the lipid flux perhaps as a lipoprotein complex, since there is a rise in nucleic acid synthesis. Stimulation of bone remodeling is observed only when high dosage of retinoic acid is given orally.
