Although prospective studies of defibrillator shock overdose cannot be performed in man, the therapeutic indices of various defibrillating current waveforms can be measured in animals. We determined the ratios TD50/ED50 and LD50/ED50 (where TD50 = median "toxic" or damage-inducing dose, ED50 = median effective or defibrillating dose, and LD50 = median lethal dose) as measures of the therapeutic...

in order to investigate the tolerance of wild barley (hordeum spontaneum), wild oat (avena ludoviciana) and different wheat (triticum aestivum) cultivars to metribuzin (sencore®), a completely randomized design experiment was conducted in ferdowsi university of mashhad. the treatment were replicated three times and included wheat cultivars (atila, chamran, niknejad, dorum, gaskojen), weed speci...

Previously obtained picolinic acid benzylamide is a potent anticonvulsant with low neurotoxicity. In search for new effective anticonvulsants twelve new benzylamides (1-12) were synthesized and preliminary evaluated in the Anticonvulsant Screening Program (ASP) of Antiepileptic Drug Development Program (ADDP) of NIH. Two of them appeared the most promising: 1-cyclopentenecarboxylic acid benzyla...

BACKGROUND Thalidomide has been recognized as having an anti-allodynic effect against neuropathic pain induced by spinal nerve ligation. Its clinical beneficial effects are mainly derived from its immune-modulating property, which is known to influence the analgesic action of morphine. The possible characteristics of systemic interactions between thalidomide and morphine in the context of spina...

A series of potential anticonvulsants have been synthesized. There are eight fluorobenzylamides and three chlorobenzylamides of isocyclic or heterocyclic acids. Two not halogenated benzylamides were also synthesized to compare the effect of halogenation. The aim of the research performed was to evaluate whether halogenation of the mother structure is able to improve its anticonvulsant activity....

The methanol and ethyl acetate (EA) extracts of four species of sea lily (Himerometra magnipinna, Comaster multifidus, Comanthina sp., and Comatella maculata) were evaluated for their insecticidal activity against Yellow-fever mosquito larvae (Aedes aegypti) and their repellency against adult Asian Tiger mosquitoes (Aedes albopictus). The 24-hr minimum inhibition concentration (MIC) data reveal...
