Antitumor effectiveness and mechanism of action of Ru(II)/amino acid/diphosphine complexes in the peritoneal carcinomatosis progression.

Peritoneal carcinomatosis is considered as a potentially lethal clinical condition, and the therapeutic options are limited. The antitumor effectiveness of the [Ru(l-Met)(bipy)(dppb)]PF(1) and the [Ru(l-Trp)(bipy)(dppb)]PF(2) complexes were evaluated in the peritoneal carcinomatosis model, Ehrlich ascites carcinoma-bearing Swiss mice. This is the first study that evaluated the effect of Ru(II)/amino acid complexes for antitumor activity in vivo.

IFN-gamma role in granuloma formation in experimental subcutaneous cysticercosis.

Cysticercosis is an infection caused by the metacestode larval stage of Taenia parasites in tissues and elicits a host-parasite reaction in which the immune response may be decisive in the disease development. The aim of this study was to evaluate the role of IFNγ (IFN-gamma) in the experimental model of subcutaneous infection with Taenia crassiceps (T. crassiceps) cysticerci using IFNγ knockout mice.
