The effects of albendazole and Yin-Chen-Extract co-therapy on Angiostrongylus cantonensis-induced eosinophilic meningitis in BALB/c mice were evaluated. Assay indicators for the therapeutic effect include worm recovery, histopathological score of the fourth ventricle, tissue-type plasminogen activator, urokinasetype plasminogen activator, matrix metalloproteinase-9, cerebrospinal fluid total protein, leukocyte counts, and proinflammatory cytokines. As a result, albendazole and Yin-Chen-Extract co-therapy significantly decreased (P < 0.05) these factors. Although Yin-Chen-Extract may possess pharmacologic activities beneficial to the inhibition of parasite-induced inflammation, many of these hypothetical benefits await scientific testing and confirmation before application. This study suggests that the combination of Yin-Chen-Extract and albendazole has synergistic effects in managing eosinophilic meningitis or eosinophilic meningoencephalitis.
