As from January 2010 The Israeli Journal of Aquaculture-Bamidgeh (IJA) will be published exclusively as an on-line Open Access (OA) quarterly accessible by all AquacultureHub (http://www.aquaculturehub.org) members and registered individuals and institutions. Please visit our website (http://siamb.org.il) for free registration form, further information and instructions. This transformation from a subscription printed version to an on-line OA journal, aims at supporting the concept that scientific peer-reviewed publications should be made available to all, including those with limited resources. The OA IJA does not enforce author or subscription fees and will endeavor to obtain alternative sources of income to support this policy for as long as possible.

Following initial signs of dural infection, or as prophylactic postoperative therapy, three cynomologus macaques were given an intramuscular or a subcutaneous injection of ceftriaxone dissolved in a 1% lidocaine diluent (CL). Two to 15 min later, all three monkeys experienced a long-lasting generalized apnoeic clonic convulsive seizure. The injected doses of lidocaine (0.7-2 mg/kg) were as low as 7-20-fold less than the experimental intravenous dosage (14.2 + 3.2 mg/kg) previously reported to induce seizure in healthy rhesus monkeys. Under different clinical conditions, the same three animals were either once (1 animal) or repeatedly given CL without any resultant neurological alterations. The monkeys had a cranial device implanted and two of them were craniotomized. This first report of accidental lidocaine-induced seizure in laboratory non-human primates following CL injection strongly suggests increased susceptibility when lidocaine administration is associated with central nervous system alteration. A novel hypothesis, the possible role of cytokine in lowering the lidocaine seizure threshold, is suggested.
