In view of the importance of the biochemical aspect and its direct and indirect relationship with the various damage that occurs in different tissues, it has been necessary to study chemical changes in natural and pathological conditions.
The present study was conducted to evaluate the effect of active substances in the aqueous and alcoholic extracts of Nerium oleander on the Protoscolies viability of the echinococcus in vivo. The protoscolies were collected from livers of sheep naturally infected with Hydatid Cysts at Tikrit slaughterhouse. The viability of these Protoscolies was measured using the eosin aqueous stain. The results showed that there are significant differences in the concentrations of Nerium oleander for aqueous and alcoholic extracts. The alcoholic extract at a concentration of (270) mg / ml achieved good results, as the values of protein, glucose, triglycerides, urea, creatine, magnesium, sodium, potassium and zinc increased, while the values of liver enzymes GOT, GPT, and ALP decreased in the treated animals.
