The crude alcoholic extract of Spirugera sp. algae with concentrations (250, 500, 1000) mg/ml and albendazole with concentrations (250, 500, 1000) mg/ml effects was studied in the viability of protoscolices in vitro, the viability of the protoscolices in 10 microliters and the three replicates calculated in the fixed-size method. There were no significant differences in the first three treatments (0,24,48 hour), whereas the coefficients of 72-144 hour showed significant differences . The mean S.D. ± viability of the protoscolices at the highest rate at treatment at 0 hour (33 ± 5.29) protoscolices, while the mean of the protoscolices dropped to the lowest ratio at 144 to 14 ± 1 protoscolices. While the mean S.D.± mean of the protoscolices viability of the treatments 24-120 hours between 31.33 ± 1.52-16.66 ± 1.52 protoscolices. The total number of protosclices ranged from 177-193. The average number of live protoscolices ranged between 170-177 protoscolices / 100 µl , While the number of dead protoscolices ranged from 6-16 protoscolices / 100µl. Sixty-nine chemical compounds were extracted from the crude alcoholic extract of Spirogyra sp. Varied between phenols, turbines, fatty acids, hydrocarbons and hetero cyclic compounds. The results of this study showed a decrease in the percentage of the viability of the protoscolices when exposed to the concentrations of the crude alcoholic extract of the Spirugera sp. The concentration of 250 mg / ml resulted in a decrease in the percentage of protoscolices from 92.75±0.62 at 0 hour to 27.06±0.48 at 144 hour compared with control group (76.56 ± 0.79), while the concentration of 500 mg/ml decreased from 92.59±0.58 per hour to 0.14±0.25% at 144 hours compared with the control group, while the concentration was 1000 mg /ml has led to the killing of all protoscolices at 144 hour compared with the control group, The results of used albendazole drug showed significant differences. concentrations reduced the percentage of viability of protoscolices. When exposed to 250 mg / ml, The result was a decrease from 93.75 ± 0.77 at 0 hour to 4.15 ± 0.36 at 144 hour, while the concentration of 500 mg / ml reduced the percentage from 48 ± 0.85 at 0 hour to 0,4±0.48 at 144 hour, while The concentration of 1000 mg / ml resulted in the killing of all protpscolices indications at 120 hour compared to 0 hour where the percentage of viability of protoscolices was 45.5 ± 0.98. The results of this study showed that a similar effect of a Spirogyra sp extract and albendazole drug on the viability of the protoscolices with increased concentration and duration of exposure to the drug or alcoholic extract.
