1. Vitamin C (Ascorbic acid) protects from neuropathy caused by cisplatin, through enhanced heat shock protein-70 and reduced oxidant effect
SUMMARY OBJECTIVE: We aimed to determine whether vitamin C has a protective effect on cisplatin-induced neuropathy in rats. METHODS: In total, 24 rats were included in the study of which 8 rats (no drug administered) were categorized as the control group. The remaining 16 rats were given a total dose of 20 mg/kg cisplatin to induce neuropathy. These drug-a

2. Effects of Lippia sidoides essential oil, thymol, p-cymene, myrcene and caryophyllene on rat sciatic nerve excitability
Lippia sidoides Cham is a typical herb species of Northeast Brazil with widespread use in folk medicine. The major constituents of the essential oil of L. sidoides (EOLs) are thymol, p-cymene, myrcene, and caryophyllene. Several studies have shown that the EOLs and its constituents have pharmacological effects, including antibacterial, anti-inflammatory, ant

3. Tibial and fibular nerves evaluation using intraoperative electromyography in rats
ABSTRACT PURPOSE: To evaluate a new model of intraoperative electromyographic (EMG) assessment of the tibial and fibular nerves, and its respectives motor units in rats. METHODS: Eight Wistar rats underwent intraoperative EMG on both hind limbs at two different moments: week 0 and week 12. Supramaximal electrical stimulation applied on sciatic nerve, and

4. Limb immobilization alters functional electrophysiological parameters of sciatic nerve
Immobilization, used in clinical practice to treat traumatologic problems, causes changes in muscle, but it is not known whether changes also occur in nerves. We investigated the effects of immobilization on excitability and compound action potential (CAP) and the ultrastructure of the rat sciatic nerve. Fourteen days after immobilization of the right leg of

5. Análise dos parâmetros eletrofisiológicos do nervo ciático e gânglio da raiz dorsal decorrentes de um período de imobilização da pata traseira direita de ratos diabéticos. / Analysis of the electrophysiological parameters of the sciatic nerve and dorsal root ganglia derived from a standstill of the right hind paw of diabetic rats.
Diariamente, milhares de pessoas passam por limitações físicas provisórias decorrentes da imobilização de alguma parte de seu corpo, podendo resultar numa alteração de sua função orgânica normal. Entretanto, esta situação poderá agravar-se quando o paciente for diabético, devido a alterações metabólicas e do sistema nervoso motor e sensitiv

6. Estudo das alterações eletrofisiológicas produzidas pelo estragol sobre os axônios do nervo ciático e os neurossomas do gânglio da raiz dorsal de ratos / Study of electrophysiological changes produced by estragole on the sciatic nerve axons and the neurossomas the dorsal root ganglion of rats
Estragol (EST) é usado como aromatizante na indústria de alimentos e cosméticos. Este é um constituinte natural de vários óleos essenciais de muitas plantas do Nordeste do Brasil. Ele apresenta muitas ações biológicas como: anestésica, hipotérmica, antimicrobiana, miorrelaxante e antiespasmódica. Neste estudo, nós verificamos o efeito do estrago

7. Efeito da castração sobre o potencial de ação composto do nervo ciático de ratas. / Effect of castration on the compound action potential of the sciatic nerve of rats.
O estrogênio e a progesterona são os principais hormônios sexuais ovarianos. Esses hormônios são responsáveis por diversas atividades biológicas. Neste estudo, nós verificamos os efeitos do estrogênio e da progesterona no PAC dos nervos ciáticos de ratas no grupo de ratas com ligadura ciática (RL), ratas ooforectomizadas (RO) e ratas ooforectomiza

8. Effects of estragole on the compound action potential of the rat sciatic nerve
Estragole, a relatively nontoxic terpenoid ether, is an important constituent of many essential oils with widespread applications in folk medicine and aromatherapy and known to have potent local anesthetic activity. We investigated the effects of estragole on the compound action potential (CAP) of the rat sciatic nerve. The experiments were carried out on sc

9. Effects of terpineol on the compound action potential of the rat sciatic nerve
Terpineol, a volatile terpenoid alcohol of low toxicity, is widely used in the perfumery industry. It is an important chemical constituent of the essential oil of many plants with widespread applications in folk medicine and in aromatherapy. The effects of terpineol on the compound action potential (CAP) of rat sciatic nerve were studied. Terpineol induced a

10. Regulation of rat nerve blood flow: role of epineurial alpha-receptors.
1. Transperineurial arterioles connect the extrinsic (epineurial) and the intrinsic (endoneurial) microvasculatures. Our goal was to determine whether the extrinsic system regulated nerve blood flow locally and whether subperineurial and centrifascicular endoneurial nerve blood flows were regulated differentially. 2. The local application of noradrenaline re

11. Ischemic and reperfusion injury of rat peripheral nerve.
A rat model of severe nerve ischemia was used to study the effects of ischemia and reperfusion on nerve conduction, blood flow, and the integrity of the blood-nerve barrier. Conduction failure was consistently found in the sciatic-tibial nerve during 1- and 3-hr ischemic periods. Recovery of the compound muscle action potential was prompt and complete upon r

12. Sequence of demyelination-remyelination in Guillain-Barré disease.
A detailed investigation of nerve conduction was made in a patient with Guillain-Barré disease. Conduction velocity and configuration of the compound action potential in distal (median), intermediate (tibial) and central (sciatic) nerve segments were studied serially as the patient weakened and then recovered. Demyelination was found to follow a centripetal
