FIELD: medicine.
SUBSTANCE: for prophylactic treatment in case of neoplastic processes involving skin tissue, such as melanoma, basal cell carcinoma, squamous cell carcinoma, a pharmaceutical preparation is used comprising a protein-polypeptide complex (BPC) in the form of cosmetic compositions, such as day or night creams, gels, alone or in liposomal form, and also as a photoactive or photoprotective compositions as the active substance, daily at a concentration of 0.001-0.05 mg/ml 1-2 times a day with a dose of 10-20 days course not less than 4 courses per year. The active substance is a protein-polypeptide complex produced of hoofed farm animal's nerve and skin embryonic tissue homogenate and containing negatively charged weak-acid and neutral proteins and polypeptides with molecular weight from 5 to 200 kDa and containing an average molecular weight fraction within 10 to 120 kDa of not less than 80%, with the total protein concentration of 0.2-4.2 mg/ml, the ultraviolet spectrum absorption peak of the solution at wave length± 2805 nm, the UV-visible spectrum peak at wave length 274-284 nm, the presence of specific bands in the range of pl from 4.2 to 8.4 in isoelectric focusing in 5% polyacrylamide gel.
EFFECT: invention provides prevention of neoplastic skin diseases.
