Hydatid disease is an economic and public health concern in many countries. Currently, surgery is the main treatment option for hydatid disease. In the surgical treatment of hydatidosis, the use of scolicidal agents is very important due to inactivating live protoscoleces and preventing the recurrence of infection. Therefore, it is necessary to investigate newscolicidal agents and novel medications with higher safety and efficacy. In the previous in vitro studies, the scolicidal effects of the methanolic extracts and aromatic water of Zataria multiflora (Z. multiflora) have been demonstrated. Consequently, in this study, the impact of the nanoemulsion of Z. multiflora essential oil on subcutaneous hydatid cysts was compared with albendazole (ABZ). Fifty laboratory male mice were inoculated with 300 viable protoscoleces subcutaneously on the two sides of the abdomen. Following five months of infection, the remaining infected mice (n=42) were allocated into two treatment and one control (without treatment) groups containing fourteen animals each. Group A received ABZ at the dose of 50 mg/kg for 60 days, group B received the nanoemulsions of Z. multiflora at the dose of 50 mg/kg in drinking water for 60 days, and group C was considered as the control group. All the infected mice were euthanized and necropsied two months post-intervention. Afterwards, the cysts were cautiously collected and their number, size, and weight were compared between the mice of different groups. The mean number of hydatid cysts indicated that the nanoemulsion of Z. multiflora essence had a relative superiority to ABZ. On the other hand, the therapeutic effect of ABZ was higher than the nanoemulsion of Z. multiflora essential oil in terms of the mean weight and mean size of hydatid cysts. However, no significant difference was observed between the groups (P>0.5). Overall, the number, weight, and size of cysts were not significantly different between the groups in this investigation. The lack of satisfactory therapeutic results in this study might be due to the location of hydatid cysts in the subcutaneous space.
包虫病在许多国家都是一个经济和公共卫生问题。目前,手术是治疗包虫病的主要选择。在包虫病的外科治疗中,由于能使活的原头节失活并防止感染复发,使用杀头节剂非常重要。因此,有必要研究新的杀头节剂以及安全性和疗效更高的新型药物。在之前的体外研究中,已证实了百里香(Zataria multiflora)甲醇提取物和芳香水的杀头节作用。因此,在本研究中,将百里香精油纳米乳剂对皮下包虫囊肿的影响与阿苯达唑(ABZ)进行了比较。五十只实验室雄性小鼠在腹部两侧皮下接种300个活的原头节。感染五个月后,将剩余的感染小鼠(n = 42)分为两个治疗组和一个对照组(不治疗),每组各有十四只动物。A组接受剂量为50 mg/kg的阿苯达唑,持续60天,B组在饮用水中接受剂量为50 mg/kg的百里香纳米乳剂,持续60天,C组作为对照组。所有感染小鼠在干预后两个月实施安乐死并进行尸检。之后,小心收集囊肿,并比较不同组小鼠之间囊肿的数量、大小和重量。包虫囊肿的平均数量表明,百里香精华纳米乳剂相对于阿苯达唑具有相对优势。另一方面,就包虫囊肿的平均重量和平均大小而言,阿苯达唑的治疗效果高于百里香精油纳米乳剂。然而,两组之间未观察到显著差异(P>0.5)。总体而言,本研究中各组囊肿的数量、重量和大小没有显著差异。本研究中缺乏令人满意的治疗结果可能是由于包虫囊肿位于皮下空间。
