In vitro study on protoscolicidal effect of methanolic extract of Allium hirtifolium on protoscoleces of cystic echinococcosis.

Surgery is the treatment of choice for treatment of human cystic echinococcosis/ hydatidosis which is one of the most important parasitic zoonoses worldwide. Due to the risk of cyst rupture during surgery a protoscolicidal agent is usually injected into the cyst before surgery to prevent secondary cyst formation in case of cyst rupture. Due to the side effects of chemical protoscolicidals agents attempts has been focused on herbal medicine.In this regard, Allium sativum has already been used; however, the protoscolicidal effect of Allium hirtifolium from Allium family has not been investigated, so far.

The present study was conducted in order to assess the protoscolicidal effect of methanolic extract of Allium hirtifolium in different concentrations, temperature and exposure times. Cetrimide as positive control, and DMSO as negative control, were also used in this study. The viability of protoscoleces was determined by 0.1% eosin staining method.

The protoscolicidal effect of Allium hirtifolium on protoscoleces was as follows: The mean percent and standard deviation (SD) of protoscolecidal activity of 50 mg/ml concentration of Allium hirtifolium extract in room temperature at 10, 20, 30, 40 and 50 minutes of exposure was 5.88.
