Transmembrane potentials in the rat myometrium during pregnancy

Autor: Theodore C. West, Jorge F. Landa, John B. Thiersch

Publikováno v: American Journal of Physiology-Legacy Content. 196:901-904

Isolated segments of the uteri of pregnant and nonpregnant Long-Evans rats were studied by the microelectrode technique of intracellular recordings. Both action and resting membrane potentials were recorded in the following states: nonpregnant; 12, 1

Effects of potassium on frog skeletal muscle in a chloride-deficient medium

Autor: Jorge F. Landa, Gertrude Falk

Publikováno v: American Journal of Physiology-Legacy Content. 198:1225-1231

Muscle fibers give prolonged action potentials with a characteristic plateau in a medium in which chloride has been replaced by anions which do not carry charge across the membrane. Repolarization is aperiodic or oscillatory with negative damping. Du

Relationships between contraction and membrane electrical activity in the isolated uterus of the pregnant rat

Autor: Jorge F. Landa, Theodore C. West, John B. Thiersch

Publikováno v: American Journal of Physiology-Legacy Content. 196:905-909

Isolated uterine segments from 21-day pregnant rats of the Long-Evans strain were studied by the microelectrode technique in conjunction with force of contraction measurements. Dual recording from large segments showed gross discoordination in onset,

Prolonged response of skeletal muscle in the absence of penetrating anions

Autor: Gertrude Falk, Jorge F. Landa

Publikováno v: The American journal of physiology. 198

Replacement of Ringer's chloride by a variety of nonpenetrating anions results in prolonged electrical and mechanical responses of muscle to stimulation. The ‘negative after-potential’ is characterized by a slowly increasing secondary depolarizat
