immediately fixed in 4% cold-buffered formaldehyde at 4 C for
The data provide the evidence for an anthelmintic potentiality of
the extract of A. pennata root bark as traditionally used by the Mizo

was quite comparable to that of the standard drug albendazole.
Interestingly, a closely related species of the present investigation,

to exhibit similar effects on R. echinobothrida, including
changes in the vital enzymes and trace elements,15 internal and
