[Increase in ovarian K+ levels in impuberal rats treated with gonadotropins: characteristics of the phenomenon].
In Pregnant Mare Serum Gonadotrophin (PMSG) primed rat ovaries, the K+ level and 42K uptake were increased (+14% and +47% respectively). This phenomena was observed only for target organs (ovaries and testis) and was detectable 30 minutes after PMSG injection. The K+ level augmentation was still demonstrated when the macromolecules biosynthesis were blocked by actinomycin. In hypophysectomised rat, LH or FSH had the same effect as PMSG on K+ level.
