Implication

These rat tissue effects remain hypothesis-generating; leaves open whether Na/K-ATPase modulation alters human muscle or hepatic electrophysiology.

Structured PICO

Do ouabain and diphenylhydantoin alter transmembrane resting potentials, ionic gradients, and cell pH in rat muscle and liver in vivo?

P
Population
Rat muscle and liver in vivo
I
Intervention
Ouabain and diphenylhydantoin (DPH)
O
Outcome
Transmembrane resting potentials (RP), ionic gradients, and cell pHsurrogate

Ouabain and DPH alter transmembrane resting potentials and ionic gradients in rat muscle and liver, supporting a loose coupling between active H+ and Na+-K+ transport.
