title: Preventive and therapeutic effects of Zataria multiflora methanolic extract on hydatid cyst: an in vivo study.
abstract: The phenolic compounds of Zataria multiflora extract, were identified by HPLC analysis. Gallic acid, catechin, caffeic acid, and quercetin were found to be the major phenolic compounds. Eighty healthy laboratory Balb/C mice were infected intraperitoneally by injection of 1500 viable protoscoleces and were divided into prevention (40 mice) and therapeutic (40 mice) groups. To prove the preventive effect of Z. multiflora extract on development of hydatid cyst, the 40 infected animals were allocated into three treatment groups including Z. multiflora (4 g/l in drinking water for 8 months), albendazole (150 mg/kg BW/day for 10 days) and untreated (control) group. To estimate the therapeutic effect of Z. multiflora extract on the hydatid cyst, after 8 months of infection, the infected mice were allocated into three experimental treatment groups including Z. multiflora (8 g/l in drinking water for 30 days), albendazole (300 mg/kg BW/day for 20 days) and untreated (control) group. At the end of the treatment period, all mice were euthanized and necropsied, the hydatid cysts were carefully removed, weighed and their size were recorded. Weight and size of the hydatid cysts significantly decreased (p<0.05) upon the treatment with Z. multiflora extract in both prevention and therapeutic groups. The germinal layer of the hydatid cysts recovered from the treated mice, either from the prevention or therapeutic group, were completely damaged at ultrastructural level by scanning electron microscopy.
