However, a dose of crude BWME (MIC, 1750 pg/ml) and BWHE (MIC, 1750 ug/ml) exhibited a significant (p < 0.05) antifungal property against Candida albicans ATCC 10231 compared to Clotrimazole (10 ug/ml ), Fluconazole (25 pg/ml), and Ketoconazole (10 Hg/m). Pearsonothuria graeffei crude extracts are potential cytotoxic and genotoxic agents at concentrations of 500, 1000, and 1500 pg/ml. Also, a significant (p < 0.03) growth inhibition in both the length and number of roots occurred at higher concentrations of 1000 and 1500 pg/ml of the crude extracts. Finally, a low mitotic index was observed in onions treated with the crude extracts.enThesis
