Double Sucrose-Gap Method Applied to Single Muscle Fiber of Xenopus laevis
Passive electrical properties (internal conductance, membrane conductance, low frequency capacity, and high frequency capacity obtained from the foot of the action potential) of normal and glycerol-treated muscle of Xenopus were determined with the intracellular microelectrode technique. The results show that the electrical properties of Xenopus muscle are essentially the same as those of frog ...
متن کاملLimitations of the double sucrose gap voltage clamp technique in tension-voltage determinations on frog atrial muscle.
The purpose of this study was to evaluate the limitations of the double sucrose gap voltage clamp technique in the determination of tension-voltage relationships for frog atrial muscle. Tension-voltage relationships were determined under two conditions. In one case we determined both the tension response and slow inward current associated with an apparent step depolarization (step-clamp) as a f...
متن کاملDo two intravenous iron sucrose preparations have the same efficacy?
BACKGROUND Intravenous (i.v.) iron sucrose similar (ISS) preparations are available but clinical comparisons with the originator iron sucrose (IS) are lacking. METHODS The impact of switching from IS to ISS on anaemia and iron parameters was assessed in a sequential observational study comparing two periods of 27 weeks each in 75 stable haemodialysis (HD) patients receiving i.v. iron weekly a...
متن کاملMembrane Potentials of the Lobster Giant Axon Obtained by Use of the Sucrose-Gap Technique
A method similar to the sucrose-gap technique introduced be Stäpfli is described for measuring membrane potential and current in singly lobster giant axons (diameter about 100 micra). The isotonic sucrose solution used to perfuse the gaps raises the external leakage resistance so that the recorded potential is only about 5 per cent less than the actual membrane potential. However, the resting p...
متن کاملStudy on detection methods for sucrose
Sucrose is a disaccharide, composed of monosaccharides glucose and fructose with the molecular formula of C12H22O11. It has been known that sucrose is a natural product extracted from sugar beet or sugarcane and it plays a vital role in human nutrition and health. Sucrose has also been widely used as a raw material. In addition, sucrose permeability has been suggested as a simple and non-invasi...
