BACKGROUND
GABAergic interneurons in the hippocampal CA1 area are mutually communicated by gap junctions (GJs) composed of connexin36 (Cx36). We examined the role of Cx36 in CA1 in manifestation of kindled seizures and hippocampal kindling in rats.
METHODS
Quinine, as the specific blocker of Cx36,
OBJECTIVE
The selective contribution of neuronal gap junction (GJ) communication via connexin 36 (Cx36) channels to epileptogenesis and to the maintenance and propagation of seizures was investigated in both the primary focus and the mirror focus by using pharmacologic approaches with the
In vivo and in vitro evidence from animals suggesting that gap junctions (GJs) play a role in the spreading of epileptiform activity. We have examined the influence of the gap junction opener trimethylamine (TMA) and the connexin 36 (Cx36) gap junctional blocker, quinine, on epileptiform activity
BACKGROUND
In models of temporal lobe epilepsy and in patients with this pathology, high frequency oscillations called fast ripples (FRs, 250-600 Hz) can be observed. FRs are considered potential biomarkers for epilepsy and, in the light of many in vitro and in silico studies, we thought that
The effects of some GABAergic agents on seizures induced by quinine were studied in mice. Muscimol, AOAA, DABA and baclofen significantly protected mice against quinine-induced convulsions. Bicuculline effectively enhanced quinine-induced convulsions, and significantly attenuated the protective
Quinine, is an anti-malarial drug that specifically blocks connexin 36 (Cx36) at gap junction channels. Quinine has suppressed ictal epileptiform activity in vitro without decreasing neuronal excitability. Thus, we considered the possible anticonvulsant effects of quinine in the pentylenetetrazole
1. Effect of quinine on electroshock and pentylenetetrazol (leptazol)-induced seizures was investigated in mice. 2. Quinine (0.1-100 mg/kg, ip) did not protect mice against electroshock seizure. 3. 25-100 mg/kg, ip of quinine reduced the incidence of leptazol (80-90 mg/kg, sc)-induced seizure and
The intramuscular (i.m.) route is generally used for treatment of childhood falciparum malaria in outlying health care units in Togo. The purpose of this randomized therapeutic trial was to compare the efficacy and tolerance of diluted injectable quinine administered by the i.m. versus intrarectal
We report a case of 40-year-old with chloroquine- and mefloquine-resistant Plasmodium falciparum. He had a single grand mal seizure 37 days following retreatment with quinine intravenously, which resulted in rapid clearance of fever and parasitemia, in addition to mefloquine. He had a long history
Although the United States Food and Drug Administration banned its use for nocturnal leg cramps due to lack of safety and efficacy, quinine is widely available in beverages including tonic water and bitter lemon. Numerous anecdotal reports suggest that products containing quinine may produce
BACKGROUND
Quinine has anti-epileptic properties in animals. However, in humans this has not been systematically investigated.
OBJECTIVE
To examine the available research evidence on the effects of quinine on seizures in adults or children.
METHODS
We searched online databases for published and
There are abundant studies indicating that blocking gap junctions (GJs) containing connexin 36 (Cx36) inhibit seizures. However, recent evidences demonstrate proconvulsant effect of such intervention. Electrical coupling between GABAergic interneurons in CA1 region of hippocampus is mediated through
BACKGROUND
High concentrations of quinine, the drug of choice for severe malaria, are toxic to the cardiovascular system, producing hypotension and abnormal myocardial conduction.
METHODS
Five children, aged 14 months to 13 years, were admitted because of fever that appeared a few days after their
BACKGROUND
Hypoglycaemia is an independent risk factor for death in severe malaria and a recognized adverse treatment effect of parenteral quinine. In 2006 our hospital changed quinine treatment policy from 15 mg/kg loading (plus 10 mg/kg 12-hourly) to 20 mg/kg loading (plus 10 mg/kg 8-hourly) to
BACKGROUND
Quinine is used for treating severe malaria. There are arguments for giving an initial high dose. We examined the evidence for and against this policy.
OBJECTIVE
To assess the clinical outcomes and adverse events of a high first (loading) dose regimen of quinine compared with a uniform
