Vulnerability study of myelinated and unmyelinated nerve fibers in acute ocular hypertension in rabbit
In the current study, it was aimed to evaluate the changes in myelinated and unmyelinated nerve fibers in retinal ischemia‑reperfusion injuries caused by acute ocular hypertension and to determine the sequence of these changes. Adult healthy New Zealand white rabbits were randomized to the hemodynamic group [n=12; used to determine the optimal intraocular pressure (IOP) for the subsequent exper...
متن کاملDifferential contribution of sodium channel subtypes to action potential generation in unmyelinated human C-type nerve fibers.
BACKGROUND Multiple voltage-dependent sodium channels (Na(v)) contribute to action potentials and excitability of primary nociceptive neurons. The aim of the current study was to characterize subtypes of Na(v) that contribute to action potential generation in peripheral unmyelinated human C-type nerve fibers. METHODS Registration of C-fiber compound action potentials and determination of memb...
متن کاملAortic depressor nerve unmyelinated fibers in spontaneously hypertensive rats.
The objective of the present study was to compare the morphology of the unmyelinated fibers in the aortic depressor nerves (ADN) of spontaneously hypertensive rats (SHR) and Wistar-Kyoto rats (WKY). In anesthetized rats, the ADN was identified by its spontaneous activity synchronous with the arterial pulses. Thin sections of the proximal and distal segments of the ADN were analyzed by electron ...
متن کاملMorphological differentiation of nerve fibers: central, peripheral, myelinated and unmyelinated.
We have developed a new technique for the morphological differentiation of various nerve fibers which is especially suitable for the morphometric study of nerve fibers of the human nervous system with the help of an image-analyzer. The knowledge from findings by this technique, which is based on several study methods, may be of importance in promoting further neuromorphologic studies and in pro...
متن کاملMechanisms of Action of Lidocaine and Quinidine on Action Potential Duration in Rabbit Cardiac Purkinje Fibers
The effects of lidocaine and quinidine on rabbit cardiac Purkinje fibers were compared at 37 °C, using action potential and voltage clamp measurements. At therapeutic concentrations (5 /ig/ml), lidocaine shortened the duration of the action potential while quinidine lengthened it. When membrane potential was held constant between —40 and —50 mV by the application of the two-microelectrode volta...
