Histopathological and immunophenotyping studies on normal and sarcoma 180-bearing mice treated with a complex homeopathic medication.

Canova is a homeopathic complex medicine, used as an immune modulator. We studied its effects in normal and sarcoma 180-bearing mice. Three control groups were also evaluated. The mice were examined at daily intervals and the tumours observed histologically. Peripheral blood was analysed by flow cytometry. A delay in the development, and a reduction in size of the tumours, and increased infiltration by lymphoid cells, granulation tissue, and fibrosis surrounding the tumour were observed with active treatment compared to control. All animals from the treated group survived, 30% of control groups died. In 30% of treated animals, a total regression of the tumour was confirmed using light microscopy, no regression was found in the control groups. Treatment with Canova increased total numbers of leukocytes and lymphocytes. Among lymphocytes, TCD4, increased in normal-treated group and B and NK cells in S180-treated groups. The results reflect enhanced immune response of the host after treatment with Canova.
