Effects of norepinephine, calcium, and rate of discharge on 42K movements in canine cardiac Purkinje fibers.
We studied the effect of norepinephrine, calcium concentration, and rate of discharge in the presence of different [Ca2+]0 on radioactive potassium movements in cardiac Purkinje fibers. The following results were obtained: (1) norepinephrine increases potassium uptake in quiescent fibers and in fibers driven at constant rate, but more in the latter; (2) norepinephrine also increases potassium u...
متن کاملANTICONVULSANT THERAPY-INDUCED ALTERATIONS IN CALCIUM HOMEOSTASIS
35 epileptic patients, aged 10 to 58 years (mean 23), who were taking anticonvulsant drugs were studied. The patients exhibited a 34% reduction in serum calcium levels, a 41 % increase in serum alkaline phosphatase activity and a slight but insignificant decrease in serum phosphate, compared to untreated controls. These changes appear to be related to the anticonvulsant drug taken, in the ...
متن کاملDepolarization-stimulated 42K+ efflux in rat aorta is calcium- and cellular volume-dependent.
The purpose of this study was to investigate the factors controlling membrane permeability to potassium of smooth muscle cells from rat aorta stimulated by depolarization. The increase 42K+ efflux (change in the rate constant) induced by depolarization (application of high concentrations of potassium chloride) was inhibited significantly by the calcium antagonists diltiazem and nisoldipine. Par...

15 صفحه اولThe pace Maker of the Cardiac Ganglion of Limulus .polyphemus
The ganglion on the dorsal surface of the heart of Limulus polyphemus originates the impulses which cause the contractions of the cardiac muscle (1). In large specimens the portion of the dorsal nerve cord which contains the ganglion cells may be 10 or even 12 cm. in length and one naturally wonders where in the extent of this long structure the impulse actually arises. Does it arise in a speci...
