Cefazolin injection (3000 mg/kg, i.v.) in mice showed several behavioral excitations such as wild running, jumping, rolling, and finally undergoing severe convulsions followed by death. It's lower doses (500-2000 mg/kg, i.v.) were unable to produce any convulsions or behavioral excitations in mice. However, cefazolin (500 or 1000 mg/kg, i.v.) when administered before different doses of pentylen...

Convulsions Induced by 2-N-Di-n-Butylaminoethanol. HARTUNG, ROLF, PITTLE, LESTER B., and CORNISH, HERBERT, H. (1970). Toxicol. Appl. Pharmacol. 17, 337-343. Dibutylaminoethanol (Bu,AE) produces convulsions in rats leading to respiratory arrest regardless of route of administration. The lethality of 5 x LD50 doses of BuzAE can be readily overcome by artificial respiration for 2-4 hr. In vivo phr...

This study sought to determine diurnal variations in febrile convulsions, and to investigate whether such variations influenced the severity of febrile convulsions. The study involved 326 children, between ages 6 months and 6 years, with simple febrile convulsions. Data were collected systematically by interviewing witnesses within the week after febrile convulsions occurred. The frequency of f...

Enzyme cyclooxygenase (COX) is reported to play a significant role in neurodegeneration and may play a significant role in the pathogenesis of epilepsy. Bicuculline (4 mg/kg; ip), picrotoxin (8 mg/kg; ip) and electroshock (60 mA for 0.2 sec) significantly induced convulsions in male Laka mice. COX-inhibitors viz. nimesulide (2.5 mg/kg; ip) and rofecoxib (2 mg/kg, ip) administered 45 minutes pri...

PURPOSE Mutations in the PRRT2 gene have been recently described as a cause of paroxysmal kinesigenic dyskinesia, infantile convulsions with choreoathetosis syndrome and, less often, infantile convulsions. We have analysed the frequency of PRRT2 mutations in families with benign familial infantile convulsions without paroxysmal kinesigenic dyskinesia. METHODS AND RESULTS Direct sequencing of ...

Morphine, a mu-opiate agonist, and ethylketazocine, a kappa-opiate agonist, produce distinct behavioral, pharmacologic, and biochemical effects. In the mouse, large doses of morphine produce convulsions that are usually lethal and that cannot be blocked by naltrexone, whereas ethylketazocine produces nonlethal clonic convulsions that can be blocked by naltrexone. Moreover, mice made tolerant to...
