Bottom Line: Maximum protoscolicidal effect of AmB and Ag-NPs was found at concentrations of 20 and 4 mg/mL, resulting in only 82.3% and 71.6% of the protoscoleces after 60 min of incubation, respectively.In contrast, F. vulgare essential oil at concentration of 1 mg/ml and hypertonic saline 20% killed 100% protoscoleces after 5 and 10 min of exposure, respectively.However, further studies will be needed to confirm these results by checking the essential oil and its active component in the in vivo model.

ABSTRACT

Background: Surgery is the preferred treatment for hydatid cyst (cystic echinococcosis, CE). At present, various scolicidal agents have been used for inactivation of protoscoleces during surgery, but they are associated with adverse side effects. The aim of the present study was to evaluate the scolicidal effects of amphotricin B, Silver nano particles, Foeniculum vulgare Mill, essential oil and hypertonic saline against protoscoleces of hydatid cyst on an in vitro model.

Methods: Protoscoleces were aseptically aspirated from the naturally infected livers of sheep and goats. Various concentrations of AmB (2.5-20 mg/ml), Ag-NPs (0.5-4 mg/ml), F. vulgare essential oil (0.125-1 mg/ml) and hypertonic saline (10-20%) were used for 5-60 min. Eosin exclusion test was used to determine the viability of protoscoleces.

Results: Maximum protoscolicidal effect of AmB and Ag-NPs was found at concentrations of 20 and 4 mg/mL, resulting in only 82.3% and 71.6% of the protoscoleces after 60 min of incubation, respectively. In contrast, F. vulgare essential oil at concentration of 1 mg/ml and hypertonic saline 20% killed 100% protoscoleces after 5 and 10 min of exposure, respectively.

Conclusion: The results indicated weak scolicidal activity of AmB and Ag-NPs; whereas F. vulgare essential oil had potent scolicidal activity against protoscoleces of hydatid cyst that revealed the potential of F. vulgare as a natural source for the production of new scolicidal agent for use in hydatid cyst surgery. However, further studies will be needed to confirm these results by checking the essential oil and its active component in the in vivo model.

Mentions: In this investigation, eosin exclusion test was used to determine the viability of protoscoleces (19). After exposure to the eosin 0.1% (1 g of eosin powder in 1000 ml distilled water), alive protoscoleces remained colorless and showed characteristic muscular movements and flame cell activity (Fig. 1), while dead protoscoleces absorbed eosin and colored red (Fig. 2).
