Title : ANTIFILARIAL ACTIVITY OF MALLOTUS PHILLIPPINENSIS LAM. ON SETARIA CERVIE (NEMATODA: FILAROIDEA) IN VITRO
Abstract : The effect of aqueous and alcoholicc extracts of the leaves of Mallotus philippinensis (Lam.) Muell. Arg. (Kampillaka) was studied on the spontaneous movements of the whole worm and nerve-muscle (n.m.) preparation of Setaria cervi and the survival of microfilariae in vitro. Both the extracts caused inhibition of spontaneous motility of whole worm and the n.m. preparation of S.cervi charecterised by intial stimulation followed by depression of amplitude. The tone and rate of contractions remained visibly uneffected. Aqueous extract at higher concentration showed immediate reduction in tone. The concentration required to inhibit the movements of n.m. preparation was 1/5th for aqueous and 1/11th for alcoholic extract compared to that for the whole worm, suggesting a cuticular permiability barrier. The stimulatory response of acetylcholine ws blocked by aqueous extract on whole worm movements. On the microfialriae the LC50 and LC90 were 18 and 20 ng/ml for aqueous and 12 and 15 mg/ml for alcoholic extracts respectively.
