Effect of single 250 mg/kg oral dose of PZQ–LNC formulations in comparison with PZQ suspension on the total worm load recovered from S. mansoni-infected mice and reduction in adult worm burden (n=5)
Worm load | Animal group/formulation code | Significance test | |||
---|---|---|---|---|---|
Group 1: untreated control | Group 2: PZQ suspension | Group 3: PZQ–LNC-25 | Group 4: PZQ–OA–MFS–LNC-25 | ||
Total worm load | |||||
Minimum | 22.0 | 6.0–8.0 | 0.0–3.0 | 0.0–3.0 |
H=20.066* P<0.001* |
Maximum | 27.0 | 6.0–8.0 | 0.0–3.0 | 0.0–3.0 | |

Notes: Percentage of reduction: percentage of reduction between each group and Group 1. H: Kruskal–Wallis test, significance between groups was done using Mann–Whitney test. P1: P-value for comparison between Groups 1 and 2. P2: P-value for comparison between Groups 1 and 3. P3: P-value for comparison between Groups 1 and 4. P4: P-value for comparison between Groups 2 and 3. P5: P-value for comparison between Groups 2 and 4. P6: P-value for comparison between Groups 3 and 4.
Statistically significant at P≤0.05.
