## Abstract Meiotic maturation was induced in __Xenopus laevis__ oocytes when the external Ca^++^ or Mg^++^ion concentration was raised above 5 mM in the presence of the ionophore. Ionophoreβdivalent cationβinduced maturation appears to be due to the stimulation of the oocyte itself. Cytoplasm of r
Ion transport across phospholipid vesicles was studied by 7 Li and 23 Na-NMR using an aqueous anionic paramagnetic shift reagent, dysprosium nitrilotriacetate [Dy(NTA) 2 ] 3Γ , mediated by ionophores, lasalocid A and A23187. The intra-and extracellular 7 Li and 23 Na-NMR signals were well separated
