PURPOSE: The current study aimed to explore the in vivo therapeutic effects of the methanolic extracts of Citrullus colocynthis, Ruta graveolens, and Peganum harmala against hydatid cyst secondary infection.
METHODS: Aerial parts of P. harmala and R. graveolens, including leaves and stems, and seeds of C. colocynthis were collected and extracted using absolute methanol. Rats that are infected with secondary infection of hydatid cysts were treated orally and intraperitoneally according to the determined lethal doses for 30 days. Histological, hematological, and biochemical investigations were done 8 months after the infection.
RESULTS: Compared to Albendazole drug, C. colocynthis, and P. harmala, the methanol extract of R. graveolens showed higher and significant (P < 0.05) therapeutic effects on the secondary hydatid cysts growth. Those effects were represented by the reduction in the cysts' number, size, and weight; as well as the significant changes (P < 0.05) in values of hematological and biochemical parameters, the elevation of IFN-γ levels, and the decline of IL-10 and IL-4 cytokines, compared to the negative control group in both routes of treatment (oral and IP). Moreover, the histological sections showed that R. graveolens has a clear damaging effect on the hydatid cysts GL in the infected rats represented by the detachment of GL from LL and AL.
CONCLUSION: This study can open an avenue to find new therapeutics for secondary hydatid cyst infections using the studied plant extracts, especially the extract of R. graveolens.
