Abstract

Ivermectin is a macrocyclic lactone (avermectins) produced by the actinomycete Streptomyces avermitilis. In this experimental study, the effectiveness of intracystic injection of ivermectin was studied as a new approach of percutaneous treatment of cystic echinococcosis. Twelve naturally infected sheep were selected and divided into 2 subgroups: treatment group (n = 9) and control group (n = 3). In the treatment group, approximate volume of ivermectin solution needed to achieve an intracystic concentration of 10 microg/mL was injected into cysts, but in the control group, sterile distillated water was applied. No reaspiration was performed at all. In the following period of 6 months, repeated sonography revealed a significant decrease in cyst sizes and progressive solidification of the cysts in the treatment group. In the control group, volumes of the cysts were increased. No major complications occurred during or after the procedure. After 6 months, all sheep were killed and examined for macroscopic and microscopic changes. Pathologic examination in the treatment group showed pericyst hyalinization, inflammatory cells in the cyst wall, degeneration of laminated and germinal membrane, and necrotic material in the cyst cavity.

Anthelmintics (ASM)

Anthelmintics or antihelminthics are a group of antiparasitic drugs that expel parasitic worms (helminths) and other internal parasites from the body by either stunning or killing them and without causing significant damage to the host. Discover the latest research on anthelmintics here.
