[The effect of pregnant mare's serum on the level of K+ ions in the immature rat ovary]. / Action d'une gonadotrophine sérique sur la teneur en ions K+ de l'ovaire de ratte impubère

Pregnant Mare Serum Gonadotrophin enhanced potassium level in immature rat ovaries in comparison with controls, three hours after intravenous injection. In vivo 42K uptake was also 36% higher (p less than or equal to 0,01) in PMSG primed rat ovaries. This response was specific to the ovary. Experiments are carried out to determine correlation between K+ level and macromolecule biosynthesis.
