Abstract

Permeation of metal Cs+ ions from water solutions across the intact, stripped and splitted skin of 5- or 9-day old rat was studiedin vitro using vertical diffusion cells. The results showed that the stratum corneum (horny layer) of this new animal skin model represents the principal pentration barrier. The relative importance of the percutaneous absorption of Cs+ ions through transepidermal and transfolicular routes has been assessed comparing the penetration across skin without hairs and skin just haired. The results have shown that the shunt diffusion along hair follicles can be of preponderant value.
