چکیده
BACKGROUND Hydatid cysts are formed in human body can be treated clinically by surgery or drugs such as albendazole (ABZ) and mebendazole (MBZ). The purpose of this study was comparing the effects of ABZ and MBZ on glutathione-S-transferase, alkaline phosphatase and protease enzymes activities in protoscoleces of hydatid cyst. METHODS The culture supernatants containing the parasite Excretory / Secretory (E/S) products were collected every 12 h for 72 h. The E/S products of treated samples with 1μg/ml ABZ and MBZ and the control one were collected and after centrifugation then protein concentrations were measured according to Bradford method. GST, ALP and protease activities of E/S products were assessed photometrically. RESULTS The mean of GST specific activity level in treated protoscoleces with ABZ and MBZ and in control group were obtained 69.44, 132.83 and 225.47U/mg/protein/ml respectively. The mean ALP activity level in treated protoscoleces with ABZ and MBZ and in control group were detected 19.22, 22.27 and 27.85 U/mg/protein/ml respectively. The protease activity level in treated protoscoleces with ABZ and MBZ were not detected. While the mean of protease activity level in control group was 7.61U/mg/proteins. Statistical analysis showed the significant difference between protein concentrations, the specific activities of GST, ALP and protease enzymes in treated protoscoleces in comparison with control group (P<0.05). Also, the significant difference were seen between specific activities of GST and ALP enzymes in treated protoscoleces with ABZ in comparison with treated group with MBZ (P<0.05). CONCLUSION ABZ is more effective on the enzymes activities (GST and ALP) as compared with MBZ.

Echinococcus multilocularis and Echinococcus granulosus metacestode infections in humans cause alveolar echinococcosis and cystic echinococcosis, respectively, in which metacestode development in visceral organs often results in particular organ failure. Further, cystic hydatidosis in farm animals causes severe economic losses. Although benzimidazole derivatives such as mebendazole and albendaz...

OBJECTIVES Infection of humans and domestic ruminants with the larval stage (metacestode) of Echinococcus granulosus results in cystic echinococcosis (CE). The metacestode causes a space-occupying lesion in visceral organs, most commonly in the liver. Benzimidazole carbamate derivatives, such as mebendazole and albendazole, are currently used for chemotherapeutic treatment of CE. In human patie...

Background & Aim: Hydatidosis is one of the most important and prevalent parasitic diseases in Iran. Due to the fact that no definite and reliable treatment for this disease has been recorded so far, the aim of this study was to investigate the antiparasitic effect of Froriepia subpinnata (F. subpinnata) on the protoscolex stage of Echinococcus granulosus (E. granulosus) in vitro. Methods: F. ...

Background: Echinococcosis is a zoonotic parasitic disease caused by the larval stage of Echinococcus granulosus. Several native and recombinant antigens, derived from different stages of E. granulosus life cycle, have been used for vaccine trials. In vitro reared adult worms are good candidates for vaccination as they do not produce fertile egg/s and do not have any risk of contamination for r...
