The organism adaptive possibilities by pathology and aging are discussed in account of the epigenetic. The organism adaptation to inner and external factors is carried out by organism unite humoral protective system, inclusive hypothalamus-hypophysis-pineal and hypothalamus-hypophysis-thymus axises. AEDG, AEDP, EDR, KED, EW, KE short peptides are the epigenetic regulators of gene expression and protein synthesis, which can be involve to the adaptation by stress and in the activation of hypothalamus-hypophysis-pineal and hypothalamus-hypophysis-thymus axises. These short peptides regulate the synthesis of proteins of heat shock, stress-protective proteins, cytocines, fibrinolysis and hemostasis factors and can participate in primary and tardive epigenetic regulation of adaptive response by stress, pathology and aging. The early functional diagnostic of element disturbances of organism unite humoral protective system by age-associative pathology can be usefull for the detection of deficient synchronization of epigenetic mechanisms, by wich the depletion and decrease of organism reserve possibilities occurs. The use of peptide can grade the adaptive syndrome manifestation by the stress and age pathology.
