Giardia duodenalis: effects of an ozonized sunflower oil product (Oleozon) on in vitro trophozoites.

The ozonized sunflower oil product (Oleozon) was investigated to explore its cytotoxic activity on Giardia duodenalis in vitro cultivated trophozites. Oleozon produced inactivation of Giardia trophozoites in a dose- and cell density-dependent manner. Thirty microliter of Oleozon with peroxide index value of 500 equivalent-mmol of activated oxygen per kilogram were used to achieve a 100% inhibition (<-4.

Inhibitory effects of Spirulina in zymosan-induced arthritis in mice.

The anti-inflammatory effect of microalgae Spirulina was studied in zymosan-induced arthritis in mice. Four days after the intra-articular injection of zymosan (15 mg/ml), Spirulina (100 and 400 mg/kg perorally) was administered to animals for 8 days. The mice were than killed and beta-glucuronidase was measured in the synovial fluid.
