Abstract:
Placement of paper strips impregnated with a suspension of diethylstilbestrol (DES) in soybean oil into the cage of a pregnant Levant vole (Microtus guentheri [D. & A.]) causes disruption of pregnancy in almost all cases, provided the DES concentration is at least 0.062 mg/cm2 and the total area of the strips is at least 100 cm2. When the total strip area is 50 cm2 or the DES concentration is 0.031 mg/cm2, the activity of the strips is markedly reduced. © 1982, Springer Science + Business Media B.V.. All rights reserved.
