Abstract:
A method for screening potential anti-epileptic drugs using fruit fly Drosophila melanogaster which comprises:(a) generating single and double mutant fly lines of K+ channel genes in Drosophila melanogaster,(b) culturing the mutant fly lines of step (a) on Drosophila medium under standard conditions,(c) selecting the dark body mutant fly males of step (b) as opposed to nonmutant light body colour females,(d) separating the male mutant flies of step (c) under ether anesthesia,(e) supplying the mutant males of step (d) with medium containing a potential antiepileptic drug at a dose ranging between 2-4 mg/ml, depending upon the drug used, for 16-20 hrs at 20.+-.2.degree. C.,(f) administering ether anesthesia to the drug treated flies of step (e) and examining their leg shaking intensity under stereomicroscope, and(g) observing the anti-epileptic effect in the drug treated flies of step (f) wherein a reduced intensity of leg shaking, compared to leg shaking in normally fed etherized flies of step (d), is indicative of potential anti-epileptic activity in the drug.
