Effect of varying concentrations of sodium on isolated mammalian heart.

It has been found that reducing the NaCl concentration down to 0.4% produces a marked and sustained increase in the force of contraction, without any change in rate or rhythm. Further reduction, oelow 0.4%, gives a biphasic response-initial stimulation followed by marked inhibition and cardiac arrest. Irregularities appear and there is a conspicous rise in tone. A heart which has ceased to beat...

Sodium, Potassium, and Chloride Fluxes

In isolated bundles of external intercostal muscle from normal goats and goats with hereditary myotonia the following were determined: concentrations and unidirectional fluxes of Na+, K+, and C-, extracellular volume, water content, fiber geometry, and core-conductor constants. No significant difference between the two groups of preparations was found with respect to distribution of fiber size,...

Sodium Fluxes in Desheathed Frog Sciatic Nerve

Desheathed frog (R. pipiens) sciatic nerves were soaked in solutions that contained ouabain or NaN(3), in K-free solutions, or in K- and Ca-free solutions. Then, the nerves were allowed to recover in standard Ringer's solution. At various times during the soaking periods, some nerves were analyzed for Na and K, and estimates were made of the influx and efflux of Na(22). While a nerve was soakin...

Sodium Fluxes in Internally Dialyzed Squid Axons

The effects which alterations in the concentrations of internal sodium and high energy phosphate compounds had on the sodium influx and efflux of internally dialyzed squid axons were examined. Nine naturally occurring high energy phosphate compounds were ineffective in supporting significant sodium extrusion. These compounds were: AcP, PEP, G-3-P, ADP, AMP, GTP, CTP, PA, and UTP.(1) the compoun...

Sodium pertechnetate (Na99mTcO4) biodistribution in mice exposed to cigarette smoke

BACKGROUND: The biological effects of cigarette smoke are not fully known. To improve our understanding of the action of various chemical agents, we investigated the biodistribution of sodium pertechnetate (Na99mTcO4) in mice exposed to cigarette smoke. METHODS: Fifteen BALB/c male mice were exposed to the smoke of nine whole commercial cigarettes per day, 3 times/day, for up to 10 days to whol...
