The effects of long-term caffeine treatment on N-methyl-D-aspartate (NMDA)-induced seizures in mice were studied. Caffeine was added (0.3 g/l) to drinking water for 14 days and the mice ingested 60-70 mg/kg/day. During the treatment, the plasma concentrations of methylxanthines (caffeine,
The effects of long-term oral administration of low doses of caffeine (0.3 g/l) and its metabolites theophylline, theobromine and paraxanthine (each at 0.5 g/l in drinking water) on bicuculline- and pentylenetetrazol (PTZ)-induced seizures and c-fos expression were studied in mice. In addition,
Cacao bean shells contain potentially toxic quantities of theobromine, a xanthine compound similar in effects to caffeine and theophylline. A dog, which ingested a lethal quantity of garden mulch made from cacao bean shells, developed severe convulsions and died 17 hours later. Analysis of the
Energy drinks have increased in popularity in adolescents and young adults; however, concerns have been raised regarding the ingredients in energy drinks and their potential negative effects on health. Caffeine, the most physiologically active ingredient in energy drinks, is generally considered
The behavioural and electrocorticographic (ECoG) convulsant effects of several xanthine derivatives injected intraperitoneally (i.p.) were studied in genetically-epilepsy prone rats. The aim of the study was to evaluate the relationship among convulsant potency, molecular structure and lipophilicity
The aim of the present study was to investigate if prolonged status epilepticus (SE), secondary to a chemoconvulsant, can induce spontaneous recurrent seizures in dogs. Clinical records at two UK referral hospitals were searched for dogs that presented in SE secondary to intoxication. Dogs were only
