MARTINEZ, Clara et al. Immunomodulator effect of the CM-95 Solution treated magnetically in Balb/c mouse with 5- fluorouracil inoculated. Vaccimonitor [online]. 2011, vol.20, n.1, pp. 13-21. ISSN 1025-0298.

5-Fluorouracil is an antineoplastic drug used in cancer chemotherapy. It has immunosuppressant effects by inhibiting cell proliferation from the haematopoietic tissue. In this paper, the immunomodulating effect of the magnetically treated CM-95 solution in Balb/c mice inoculated with 5- fluorouracil by its rehabilitating protecting action on cell parameters of the haematopoietic tissue. Six-week old mice weighing 20-22 g were inoculated twice with magnetically treated CM-95 solution by intraperitoneal route. Then, they received 5-fluoracile in a dose of 150 mg/m² of body surface by the same route. Haematopoietic parameters such as total and differential leukocyte count were evaluated before applying the antineoplastic drug and at the third and seventh days after the application. Bone marrow and spleen cellularity as well as the microscopic observation of the histological cut of the liver and of spleen, by the technique of inclusion in paraffin dyes with 10% eosin haematoxylin, were evaluated at seven days after the application of 5 fluorouracil. The magnetically treated CM-95 solution could modulate the effects of 5-fluorouracil with protecting and rehabilitating activity for the parameters evaluated in the bone marrow, peripheral blood, spleen and liver. These results open new perspectives for the application of the magnetically treated aqueous system as immunomodulator.
