Isolation of calcium current and its sensitivity to monovalent cations in dialysed ventricular cells of guinea-pig.
Matsuda H, Noma A. Matsuda H, et al. J Physiol. 1984 Dec;357:553-73. doi: 10.1113/jphysiol.1984.sp015517. J Physiol. 1984. PMID: 6096535 Free PMC article.
The ion selectivity of the Ca2+ channels in single ventricular cells of guinea-pig was studied using a 'giga-ohm seal' patch electrode for voltage clamp and internal dialysis. ...This current persisted in the presence of 20 mM-intracellular TEA Cl and 5 mM-extracell …

The ionic requirements for the initiation of action potentials in insect muscle fibers.
Washio H. Washio H. J Gen Physiol. 1972 Feb;59(2):121-34. doi: 10.1085/jgp.59.2.121. J Gen Physiol. 1972. PMID: 5058471 Free PMC article.
The value of the space constant lambda was 1.6 mm and the calculated value of R(m) was about 1750 ohm cm(2). Action potentials could be elicited when the bathing fluid contained more than 2-5 mM Ba or Sr. Similar responses were seen with 2 mM Ca in the presence of tetraeth …

Action potentials and net membrane currents of isolated smooth muscle cells (urinary bladder of the guinea-pig).
Klöckner U, Isenberg G. Klöckner U, et al. Pflugers Arch. 1985 Dec;405(4):329-39. doi: 10.1007/BF00595685. Pflugers Arch. 1985. PMID: 2417191
With a single electrode voltage clamp we measured a capacitance of 50 +/- 5 pF per cell, an input resistance of 200 +/- 25 kOhm X cm2 and a series resistance of 44 +/- 4 Ohm X cm2. The cells had resting potentials of -52 +/- 2 mV. They did not beat spontaneously but respon …

Low resistance pathways between myocardial cells.
Weingart R, Imanaga I, Weidmann S. Weingart R, et al. Recent Adv Stud Cardiac Struct Metab. 1975;5:227-32. Recent Adv Stud Cardiac Struct Metab. 1975. PMID: 1188157
The permeabilities of the nexal membranes were 7.68-10(-3), 1.27-10(-3), and 1.4-10(-6) cm/sec for 42K, 14C-TEA, and PY. These values are 9,600, 21,000, and 220 times more than the corresponding ones for the surface membrane. The disc resistance for potassium, the main int …
