The effects of albendazole solution at scolocidal concentration in the rat brain.
Intra-operative cyst rupture is a catastrophic event in the intracranial hydatid cyst disease. Dissemination of the cyst contents may lead to severe anaphylactic reactions and an increased risk of recurrence. Several scolicidal agents have been used to eradicate the infective scolices but recurrences occur and no solution has been evaluated for its adverse effects to the brain tissue. Being a specific scolocidal agent albendazole has been shown to be 100% scolicidal in vitro. In this study, we present the electrophysiological and histopathological effects of intracerebral 2% albendazole injection in the rat brain. Vascular, neuronal and glial as well as inflammatory changes were evaluated in order to detect any adverse pharmacological effects. Electrophysiological and most microscopic parameters showed no significant effects attributable to albendazole but in 25% of the albendazole group cerebral gliosis was detected whereas no gliosis was present in the control group. It is concluded that being a specific scolicidal agent albendazole offers an efficient alternative for ruptured cerebral hydatid disease, but the significance and clinical importance of the gliosis should be further investigated.
