Abstract
PURPOSE: The present study aims to investigate the scolicidal effects of Myrtus communis L. essential oil against protoscoleces of hydatid cysts and also its toxicity in mice model. MATERIALS AND METHODS: Protoscoleces were aseptically aspirated from sheep livers having hydatid cysts. Various concentrations of the essential oil (12.5-100 μl/ml) were used for 5-30 min. Viability of protoscoleces was confirmed using eosin exclusion test (0.1% eosin staining). Moreover, 48 male NMRI mice were used to determine the acute and sub-acute toxicity of M. communis essential oil. One-way ANOVA with Tukey's post-hoc test was used to assess differences between experimental groups. RESULTS: Findings of the present study demonstrated that the M. communis essential oil at the concentration of 100 μl/ml after 5 min of exposure killed 100% protoscoleces. Similarly, the mean mortality rate of protoscoleces after 10 min of exposure to concentration of 50 μl/ml was 100%. However, lower concentrations (12.5 and 25 μl/ml) of M. communis essential oil provoked a delayed protoscolicidal effects. The LD50 values of intraperitoneal injection of the M. communis essential oil was 2.23 mL/kg body wt. No significant difference (p > .05) was observed in the clinical chemistry and hematological parameters following oral administrations of M. communis essential oil at the doses 0.05, 0.1, 0.2, and 0.4 mL/kg for 14 days. CONCLUSION: The results showed potent scolicidal activity of M. communis with no significant toxicity, which might be used as a natural scolicidal agent in hydatid cyst surgery.
