Abstrakt
The influence of galactoside-specific mistletoe lectin (ML-1) administration on defined acute phase reactants in the serum of cancer patients (mammary carcinoma, n = 4; larynx carcinoma, n = 11; TNM-stages II to IV; after appropriate surgery, chemotherapy, radiation) was studied. Regular subcutaneous injections of the optimal doses of ML-1 (1 mg/kg body weight, twice a week) yielded statistically significant increases of certain acute phase reactants (C-reactive protein, haptoglobin, coeruloplasmin, C3-complement, albumin, immunoglobulin IgM) after four weeks of treatment. However, serum concentrations of transferrin, C4-complement and the immunoglobulins IgG and IgA were found within the biological range (means +/- 2 s). The increase of acute phase reactants after administration of ML-1 correlates positively with the activity of lymphatic cells (e.g. expression of IL-2 and HLA-DR receptors) in FACS (fluorescence-activated cell sorter) staining experiments and indicates the immunoreactive potency of this substance which may be speculated to be cytokine-induced.
