Immunostimulatory effect of natural clinoptilolite as a possible mechanism of its antimetastatic ability
Many biochemical processes are closely related to ion exchange, adsorption, and catalysis. Zeolites reversibly bind small molecules such as oxygen or nitric oxide ; they possess size and shape selectivity, the possibility of metalloenryme mimicry, and immunomodulatory activity. These properties make them interesting for pharmaceutical industry and medicine. The experiments were performed on mice. Different biochemical and molecular methods were used. Micronized zeolite (MZ) adnunistered by gastric intubation to mice injected with melanoma cells significantly reduced the number of melanoma metastases. In mice fed MZ for 28 days, concentration of lipid-bound sialic acid (LSA) in serum increased, but lipid peroxidation in liver decreased. The lymphocytes from lymph nodes of these mice provoked a significantly higher alogeneic graft-versus-host (GVH) reaction than cells of control mice. After i.p. application of MZ, the number of peritoueal macrophages, as well as their production of superoxide anion, increased. However, NO generation was totally abolished. At the same time, translocation of p65 (NFxB subunit) to the nucleus of splenic cells was observed. Here we report antimetastatic and immunostimulatory effect of MZ and we propose a possible mechanism of its action.
