摘要
The ozonized sunflower oil product (Oleozon (R)) was investigated to explore its cytotoxic activity on Giardia duodenalis in vitro cultivated trophozites. Oleozon (R) produced inactivation of Giardia trophozoites in a dose- and cell density-dependent manner. Thirty microliter of Oleozon (R) with peroxide index value of 500 equivalent-mmol of activated oxygen per kilogram were used to achieve a 100% inhibition (<-4.00 log unit) of trophozoites from an initial inoculum of 15 x 104 cells. This potent effect was confirmed by transmission electron microscopy where morphological deterioration of superficial structures mainly in the ventral disc, and formation of a great number of micro vesicles in the cytoplasm were found. We concluded that a direct chemical-oxidation attack by the active substances from Oleozon (R) is one of the causes of the parasitocidal effect of this product. We suggest that the dose and cell density-de pendent effect must be taken into account when prescription of this product for giardiasis treatment in humans. (c) 2008 Elsevier Inc.
