Praziquantel (PZQ) is the drug of choice against schistosomiasis. However, PZQ was found not fully effective. A new trend from natural plant sources was used to compete schistosomiasis. In the present study, the antischistosomal activities of Curcumin extract and /or PZQ were evaluated. Parasitological and histopathological examination of liver has been explored. Moreover, Surface topography of the recovered worms was inspected by SEM. On the other hand, the total protein and DNA fragmentation percentage were estimated in infected and infected treated mice as compared to control group. Treatment of infected CD1 mice with curcumin extract alone didn't show any detectable changes in the parasitological or histological parameters. The infected mice treated with PZQ only, showed a significant decrease in the total worm burden, egg load (52%), with increase in degenerated eggs (58%) in the oogram pattern.However, treating infected CD1 mice with combined therapy (curcumin extract + PZQ) showed extremely significant reduction in female and male worm count (93% & 84%) respectively. Liver tissue egg load decreased by 88%, intestinal egg load decreased by 97%. Combined therapy decreased granuloma count and diameter with significant increase in degenerated egg in the oogram count. Moreover, the studied biomarkers, related to liver function and DNA damage were significantly improved in infected mice treated with curcumin combined with PZQ as compared to either drug alone. . In conclusion, curcumin extract in combination with PZQ has a synergetic effect and could be more promising in controlling schistosomiasis.Copy Right, IJAR, 2016,. All rights reserved.
