L-lysine, an essential amino acid for man and animals, and its metabolite pipecolic acid (PA) have been studied for their effects on pentylenetetrazol (PTZ)-induced seizures in mice. L-Lysine or L-PA i.p. significantly increased clonic and tonic latencies in a dose-dependent manner against 90 mg/kg
L-Lysine enhanced the specific [3H]flunitrazepam (FTZ) binding of bovine brain membranes in vitro. Inhibition of specific [3H]FTZ binding to brain membranes in vitro by pentylenetetrazol (PTZ) at concentrations 0.46 mM and below was reversed by increasing L-lysine concentrations in the incubation
L-Lysine (250-2,000 mg/kg) and L-histidine (1,000-2,000 mg/kg) significantly raised the electroconvulsive threshold. D-Histidine (1,000 mg/kg) was completely ineffective in this regard. Both amino acids were generally inactive in pentetrazole-, picrotoxin- and aminophylline-induced seizures, though
Lysine and its metabolic intermediates were studied for their effect on pentylenetetrazol (PTZ)-induced seizures in mice. L-Lysine at dosages above 2 mmol/kg given i.p. significantly increased seizure protection and seizure latency (the time required to develop seizures after PTZ injection) with a
A focus of epileptiform discharge was induced in rat isocortex by subpial injection of 5 microliters of 100 mM FeCl3. Control animals were prepared with saline injections. Protein synthesis was estimated by uptake of [3H]lysine and its incorporation into protein at the site of iron injection, in the
BACKGROUND
Generalized epilepsy with febrile seizures plus (GEFS+) is an autosomal dominant syndrome characterized by febrile seizures (FS) and a variety of afebrile generalized seizure types. GEFS+ has previously been linked to mutations in two genes encoding the voltage-gated sodium channel
The effects of centrally injected prostaglandins (PGE1 and PGF2 alpha), arachidonic acid and lysine acetylsalicylate were examined on the seizure activity and temperature changes produced by pentylentetrazole (PTZ) and also on maximal electroshock (MES) seizures. PGE1 antagonised both PTZ and MES
Evidence of genetic factors in seizure disorders by examination of plasma amino acid concentrations in multiply affected sibships was investigated. The strategy of multiply affected sibship ascertainment was used to reduce heterogeneity as one of several potential sources of variation in
BACKGROUND
Electroconvulsive seizure treatment is a fast-acting antidepressant therapy that evokes rapid transcriptional, neurogenic, and behavioral changes. Epigenetic mechanisms contribute to altered gene regulation, which underlies the neurogenic and behavioral effects of electroconvulsive
Our earlier observations showed that L-lysine enhanced the activity of diazepam against seizures induced by pentylenetetrazol (PTZ), and increased the affinity of benzodiazepine receptor binding in a manner additive to that caused by gamma-aminobutyric acid (GABA). The present paper provides
L-Lysine 10 mmol/kg given to mice for 1 to 10 days significantly increased clonic and tonic seizure latencies caused by 60 mg/kg pentylenetetrazol (PTZ). On day 1 the clonic and tonic seizure latencies were increased from 160.4 +/- 26.3 and 828.6 +/- 230.8 s to 286.1 +/- 103.3 and 982.3 +/- 98.6 s,
Lysine is one of the indispensible amino acids and L-lysine monohydrochloride (LMH) is widely available to public as a nonprescription oral supplement. Potential clinical usefulness of oral LMH supplements has been indicated in stroke, hypertension, and seizure induced by pentylenetetrazole (PTZ),
