Intracellular free sodium and potassium, post-carbachol hyperpolarization, and extracellular potassium-undershoot in rat sympathetic neurones [PDF]
, 1983 Double-barrelled ion-sensitive microelectrodes were used to record the free intracellular Na+- and K+-concentrations ([Na+]i, [K+]i) and to determine their relation to changes in membrane potential and extracellular K+ ([K+]e) in rat sympathetic ganglia.

Changes in intracellular ion activities induced by adrenaline in human and rat skeletal muscle [PDF]
, 1988 To study the stimulating effect of adrenaline (ADR) on active Na+/K+ transport we used double-barrelled ion-sensitive micro-electrodes to measure the activities of extracellular K+ (aKe) and intracellular Na+ (aNai) in isolated preparations of rat soleus

Sodium chloride transport of normal and dietary enlarged rat cecum in vitro [PDF]
, 1998 Sodium chloride transport across isolated cecum mucosa was investigated in normal rats and rats with adaptive cecum growth induced by dietary polyethylene glycol (PEG). The normal cecum absorbed CI in excess of Na with a small short-circuit current (Isc).

Hypertension, 2016 In this brief article, we summarize recent reports about endogenous ouabain (EO), a cardiotonic steroid hormone. This includes analysis of mammalian EO, the discovery of EO isomers, regulation of intracellular signaling by EO, and the roles of EO in hypertension, pregnancy, and heart and kidney diseases.

Ouabain enhances ADPKD cell apoptosis via the intrinsic pathway
Frontiers in Physiology, 2016 Progression of autosomal dominant polycystic kidney disease (ADPKD) is highly influenced by factors circulating in blood. We have shown that the hormone ouabain enhances several characteristics of the ADPKD cystic phenotype, including the rate of cell ...

Mechanism of NaCl transport-stimulated prostaglandin formation in MDCK cells [PDF]
, 1987 Recently we have found that stimulation of NaCl transport in high-resistance MDCK cells enhances their prostaglandin formation. In the present study, we investigated the mechanisms by which prostaglandin formation could be linked to the ion transport in ...

Stabilisation of Na,K-ATPase structure by the cardiotonic steroid ouabain [PDF]
, 2013 Cardiotonic steroids such as ouabain bind with high affinity to the membrane-bound cation-transporting P-type Na,K-ATPase, leading to complete inhibition of the enzyme.

THE EFFECT OF LITHIUM ON THE INOTROPIC EFFECT OF OUABAIN AND MANIFESTATION OF ARRHYTHMIA IN GUINEA-PIG ATRIA [PDF]
Acta Medica Iranica, 1995 rli....xposure ofthe guinea-pig whole a/ria to lithium (1 and 5 mM) produced a reduction ofinotropic response to ouubain. The inhibitory effect oflithium (1 m"f) was slight, whereas lithium (5 mM) significantly reduced tlze response oj the preparations ...

Frontiers in Physiology, 2020 The cardiotonic steroids (CTS), such as ouabain and marinobufagenin, are thought to be adrenocortical hormones secreted during exercise and the stress response. The catalytic α-subunit of Na,K-ATPase (NKA) is a CTS receptor, whose largest pool is located
