Interestingly, retinol, 13-cis-retinoic acid and retinyl-acetate, the retinoids that proved capable of Pgp and ABCG2 inhibition, increased the DPH fluorescence anisotropy val- ues significantly in the case of all tested cell lines, while the other retinoids investigated had no significant effect (...
To understand how retinoids that are stored as retinyl esters (REs) within the lung are utilized in response to an inflammatory stimulus during ALI, we first analyzed concentrations of the two predominant retinoid species present in the lung, retinyl esters (RE) and all-trans-retinol (ROH), at...
The yolks and the embryos contained all-trans-retinol, 3,4-didehydroretinol and retinyl esters. There was no significant difference in the total retinoid content in the yolks of 11-day incubated eggs among hens fed for 7 weeks diets containing 0.5鈥 6.6 mg PCB/kg diet. However, the ...
Five animals re- ceived daily retinol supplementation (5 mg/kg, Aquasol A delivered by intramuscular injection), and five received vehicle injections alone. Gesta- tional control animals included premature baboons delivered at 140 d (5). At the time of killing by intravenous infusion of excess ...

Pharmacokinetically, the major difference between isotretinoin and etretinate is the much longer elimination half-life (120 days) of etretinate following long term administration. Recently, however, blood concentration versus time curves from day 1 to day 180 of etretinate therapy have been fitted...
