METHOD FOR PREPARING AGENT FOR MAINTAINING THERAPY POSSESSING TISSUE-SPECIFIC ACTIVITY

FIELD: medicine, peptides. ^ SUBSTANCE: invention relates to a method for preparing a peptide complex from animal raw possessing the tissue-specific activity. Method for preparing an agent for maintaining therapy possessing tissue-specific activity involves milling calf or pig organs of age 12 months, not above, addition of 3% acetic acid solution at temperature 20 ± 5°C and extraction is carried out at constant stirring. Then, in 30 min zinc chloride 1% solution is added, mixture is cooled to temperature 7-16°C at constant stirring followed by stirring for every 1 h in each 4 h and settling for 48 h. Extract is separated from inert substances by separation and acetone is added to extract in the volume ratio = 1:5, mixture is kept at 3-5°C for 4 h and formed precipitate is washed out with out with two-fold volume of acetone cooled to temperature 7-16°C, formed precipitate is rubbed through a metallic sieve and prepared end product is dried at temperature 18 ± 2°C. The end product represents a peptide complex with the content of low-molecular peptide fraction from 70% to 90% and with molecular mass of its peptide components in the range 1000-12000 Da wherein this complex comprises amino acids, mineral substances, trace elements and vitamins in biologically bound form. The complex elicits the expressed tissue-specific activity based on the proposed sequence of technological procedures and conditions for their realization involving temperature, temporal and other indices, and by using substances including the parent raw, a definite extractant and others. Peptide component in the prepared complex has no denaturating properties and retains its regulatory properties that suggests its using as an agent for carrying out the maintaining therapy. The proposed agent can be used in medicinal practice as an agent used in carrying out the maintaining therapy. ^ EFFECT: improved preparing method, valuable medicinal properties of agent. ^ 9 cl, 42 tbl, 14 ex
