چکیده انگلیسی
Frog skin structure and physiology differs between skin regions, however little is known about how these differences affect transdermal absorption of chemicals. Further, no information is available regarding how the relative lipophilicity of a chemical influences its transdermal pharmacokinetics in frog skin. This study investigated the in vitro percutaneous absorption of three model chemicals - benzoic acid, caffeine, and ibuprofen - through dorsal and ventral skin of the tree frog Litoria caerulea. Flux was significantly higher through the ventral skin for all chemicals. Relative lipophilicity affected flux differently in different skin regions. These differences are likely due to significantly thicker dorsal skin increasing absorption path length, and also possibly owing to lipoid secretions on the dorsum providing an additional diffusional barrier. This knowledge can advise risk mitigation of xenobiotics in agricultural and industrial settings, and also guide selection of chemicals and doses when considering transdermal drug therapy in captive frogs.
