lactic acid/seizures

Cerebrospinal fluid (CSF) and serum lactic acid levels were prospectively assayed in 42 children less than 5 years old with febrile convulsions who were divided into two groups for analytical purposes, irrespective of aetiology of pyrexia. One group (24 children) had brief febrile seizures and the

Cerebrospinal fluid/serum lactic acid was prospectively assayed in 42 patients with febrile convulsions. Patients were divided into two groups for analytical purposes. Those with brief febrile seizures (30 patients) and the remaining 12 patients had prolonged febrile seizures. CSF and serum lactic

Fluoroacetic and fluorocitric acid toxicity is often characterized by seizures, however the mechanism of this activity is unknown. Intrathecal (i.t.) injection of fluorocitrate in mice resulted in seizures after an average latency of 15 s, while intracerebroventricular (i.c.v.) injection produced

BACKGROUND Traumatic brain injury is a major cause of morbidity and mortality worldwide, and has been reported to be one of the risk factors for epileptic seizures. Abnormal blood lactate (LAC) and base deficit (BD) reflects hypoperfusion and could be used as metabolic markers to predict the

Previous studies have shown that physiological stimulation of brain activity increases anaerobic glucose consumption, both in humans and in experimental animals. To investigate this phenomenon further, we measured extracellular lactate levels within different rat brain regions, using microdialysis.

Seven patients admitted to hospital during or immediately after status epilepticus or recurrent episodes of grand-mal seizures had very high concentrations of uric acid in their blood at a time when the blood-urea was normal in five of them. The blood-lactic-acid was high in the five patients in

A 4-month-old girl developed convulsion in the neonatal period, which was focal motor seizures in the initial stage and later became spasm and tonic spasm. And the girl also had psychomotor retardation and recurrent pulmonary infection. Electroencephalography showed hypsarrhythmia, normal results

Analysis of cerebrospinal fluid lactic acid levels in 62 patients suspected of having meningitis was performed. Lactic acid was measured enzymatically using lactic acid dehydrogenase with the liberation of NADH. In a control (no meningitis) group, 46 children had a mean cerebrospinal fluid lactic

Mitochondrial encephalomyopathy with lactic acid and stroke-like episodes (MELAS) is a multisystem mitochondrial disorder that typically presents in childhood. We describe the follow-up of a patient who was diagnosed with late-onset MELAS at the age of 49. Her clinical course includes sensorineural

Despite the widespread use of isoniazid, suicidal ingestion is rare. Two patients are presented who ingested 5 gm and 12 gm respectively, both having seizures within two hours and severe metabolic adisosis. They were treated successfully with intravenous administration of diazepam and bicarbonate,

We report three children, each of whom seemed to have a primary mitochondrial disorder at presentation but was eventually diagnosed with an extramitochondrial inherited metabolic disease. The first patient presented at 6 months with developmental delay. Magnetic resonance imaging showed an abnormal

The DuPont ACA lactic acid procedure was evaluated for use on cerebrospinal fluid (CSF). The method was linear to at least 13.9 mmol per L, day-to-day precision ranged from 3 to 9 percent (CV), and recovery of lactate added to cerebrospinal fluid averaged 104 percent. The method correlated closely

Studies have shown that glycolysis increases during seizures, and that the glycolytic metabolite lactic acid can be used as an energy source. However, how lactic acid provides energy for seizures and how it can participate in the termination of seizures remains unclear. We reviewed possible

Intracerebral dialysis in conscious freely moving rats was used to examine the involvement of the N-methyl-D-aspartate (NMDA) receptor in the formation of lactic acid and its consequent appearance in extracellular fluid. Local administration of NMDA in the striatum of conscious, freely moving rats

Lactic acidosis results from an acid-base balance disorder of the body due to an excess of lactic acid. It is frequently found in critically ill patients admitted to the intensive care. The most common cause is type A, found in pathologies such as cardiogenic, septic and hypovolemic shock, trauma
