The histoenzymatic characteristics of regenerating myofibers of rat masseter muscle following injection of 1% lidocaine, as well as morphometric and histochemical characteristics of the typical myofibers, were investigated. Myoblasts appeared initially by day 1 among numerous macrophages within the
The alterations due to the long-term degeneration and regeneration of the rabbit facial nerve were investigated. The facial nerve was blocked with conventional lidocaine and bupivacaine solutions. The rabbits were sacrificed and facial nerves were removed 2, 4, 6 and 8 weeks after the administration
OBJECTIVE
The neurotoxicity of lidocaine is not fully understood, and the primary lesion of lidocaine-induced spinal neurotoxicity has not been defined. Here we examine the effects of various concentrations of intrathecally administered lidocaine.
METHODS
Forty-seven Wistar rats received 20%, 10%,
The effect of lidocaine-HCl on muscle spindles in the masseter muscle of developing mice was investigated. Repeated injections of mice with anesthetic in the short term decreased the diameters of primary endings, intrafusal muscle fibers and outer capsules in the equatorial regions of muscle
BACKGROUND
Due to its potential beneficial effects, intra- and postoperative application of intravenous lidocaine has become increasingly accepted over the last couple of years, e.g. in patients undergoing laparoscopic surgical procedures. Based on its beneficial properties, lidocaine was introduced
Analgesic discoblock is widely used for the diagnosis or treatment of discogenic low back pain by injecting local anesthetics. The purpose of this study was to investigate the deleterious effects of local anesthetics on degenerated rabbit intervertebral disks (IVDs) using an organotypic culture
BACKGROUND
Analgesic discography (discoblock) can be used to diagnose or treat discogenic low back pain by injecting a small amount of local anesthetics. However, recent in vitro studies have revealed cytotoxic effects of local anesthetics on intervertebral disc (IVD) cells. Here we aimed to
BACKGROUND
Neutrophils play a crucial role in the pathogenesis of acid-induced acute lung injury. Lidocaine inhibits the function of neutrophils. This study aimed to determine whether lidocaine attenuates acute lung injury induced by hydrochloric acid (HCl) instillation.
METHODS
In study 1, rabbits
The cardioprotective effects of a new antiarrhythmic drug, TYB-3823 [1-(2,6-dimethylphenyl)-dimethylaminoguanidine hydrochloride] were examined in the working hearts of rats and compared with those of lidocaine. Before ischemia, TYB-3823 at 5 x 10(-5) M produced a slight negative inotropic effect,
Lidocaine is a common local anesthetic and antiarrhythmic drug that acts via the local anesthetic effect of blocking voltage-gated sodium channels in peripheral neurons. To evaluate lidocaine as a therapeutic agent, we investigated optimal concentrations and effects of intravesical Prior studies in dogs with normal hearts have demonstrated that lidocaine increases but procainamide does not change the energy required for successful defibrillation. Because many postinfarct patients receiving implantable cardioverter defibrillator devices require adjunctive antiarrhythmic
BACKGROUND
Neuropathic pain, is caused by damage or disease affecting the somatosensory nervous system, leads to deterioration of the quality of life of patients. Most commonly, this deterioration is due to the inefficacy of treatment or to the adverse effects of systemic treatment. Pharmacotherapy
BACKGROUND
The efficacy of antiarrhythmic drugs in terminating sustained monomorphic ventricular tachycardia (SMVT) was assessed in a retrospective manner to provide a basis for recommending their use.
RESULTS
The 90 patients were included in this study to evaluate the efficacy to terminate SMVT
Intravenous injection of amiodarone, a class III anti-arrhythmic is widely used for persistent refractory arrhythmias. We present a case report suggesting the efficacy of amiodarone in refractory ventricular fibrillation (Vf) during weaning from cardiopulmonary bypass (CPB). A 66-year-old woman with
Radiation-induced neuropathic pain is a rare but devastating complication following cancer treatment. It is often progressive, refractory to conservative treatment, and sometimes irreversible. The exact mechanism of radiation-induced neuropathic pain is unknown, but it is associated with perineural
