Solid pieces of fetal locus coeruleus (LC) or superior cervical ganglion (SCG) were placed into a fimbria-fornix lesion cavity in 6-hydroxydopamine-treated, noradrenaline (NA)-denervated rats. Six to 8 months later, all animals were subjected to electrical kindling stimulations in the hippocampus
1. The ganglion blocking agents, chlorisondamine, pentamethonium, mecamylamine, decamethonium and hexamethonium all block nicotine extensor convulsions when administered intraventricularly in mice. Tetraethylammonium was inactive.2. For the intraventricular route, there is a relationship between
Recent years have witnessed a marked improvement in the safety and accuracy of nerve blocks with the help of ultrasound and other visualization technologies. This study reports a challenging case of a severe complication during the ultrasound-guided stellate ganglion Stellate ganglion block is a selective sympathetic block that affects the ipsilateral head, neck, upper extremity and upper part of the thorax. Convulsions are a recognized complication of intra-arterial injection during stellate ganglion block. As central nervous system toxicity depends ultimately
Two case reports illustrate that low doses of local anaesthetics such as bupivacaine 2.5 mg and a mixture of bupivacaine 1.25 mg and lidocaine 5 mg can induce grand mal seizures if injected into the vertebral artery during stellate ganglion block. The effect of the dose of local anaesthetic agent
The results of EEG investigations after Spiller-Frazier's operation for trigeminal neuralgia in 112 patients are reported. Follow-up EEGs were recorded within 1-8 years after surgery; two to three follow-up tracings were available in 53 patients. Two distinct phases of EEG alterations were noted: 1)
OBJECTIVE
Autonomic consequences of seizures are common, but can be severe. We sought to define changes in autonomic activity from limbic cortical seizures and their impact on the heart.
METHODS
We studied kainic acid (KA)-induced seizures in urethane-anesthetized rats using peripheral nerve, blood
Changes in arterial pressure (AP) and venous tone were studied in Krushinskiĭ-Molodkina (KM) rats genetically predisposed to audiogenic seizure, during the audio stress and 20 min after it. The venous tone was estimated by the mean circulatory filling pressure (MCFP) during a short arrest of
We describe the case of a patient who, during the percutaneous thermocoagulation of the petrous ganglion of Andersch, suffered a serious vagal response resulting in cardiac arrest, collapse, and generalized convulsions. Notwithstanding such major symptoms, the postoperative examination revealed no
The expression of the constitutive transcription factors activating transcription factor-2 (ATF-2), serum response factor (SRF) and cAMP/Ca response element binding factor (CREB), and the phosphorylation of SRF and CREB were studied in the untreated adult rat nervous system and following seizure
