ABSTRACT
Hepatic injury is the major limitation of long-term albendazole administration in patients with cystic echinococcosis (CE), which could give rise to cessation of treatment. The objective of the present study was to evaluate the protective effects of Zataria multiflora aromatic water (AW) against the hepatic injury induced by long-term albendazole treatment in mice with CE. Fifty healthy BALB/c female mice were infected intraperitoneally by injection of 1500 protoscoleces per animal. Five months after infection, the infected animals were divided into five treatment groups including Z. multiflora (40ml/l in drinking water for 90days), albendazole (200mg/kg/day for 90days), Z. multiflora+albendazole 200 (40ml/l Z. multiflora and 200mg/kg/day albendazole for 90days), Z. multiflora+albendazole100 (40ml/l Z. multiflora and 100mg/kg/day albendazole for 90days), and untreated (control) group. At the end of the treatment period, anesthesia was performed and blood samples were collected directly from the heart prior to euthanasia. Liver variables and oxidative stress markers were measured in the blood serum samples. A decrease in serum liver enzyme activity in the both Z. multiflora+albendazole groups was observed when compared to control, Z. multiflora and albendazole groups; however, the results for Z. multiflora+albendazole 100 were significant (p<0.007) and superior compared to those for Z. multiflora+albendazole 200. No significant differences for oxidative stress markers were observed between the different groups. The results of the present study revealed that a combined therapy with Z. multiflora AW and albendazole is effective against hepatic injury induced by CE and/or long term albendazole administration in mice with cystic echinococcosis.
