The influence of polypeptide liver complex and tetrapeptide KEDA on organism physiological function in norm and age-related pathology
By Kuznik BI, Khasanova NB, Ryzhak GA et al.
The applying of many drugs in elderly and old people often is the reason of liver dysfunction. Thereat, the risk of liver fibroid induration, acute and chronic hepatitis increases during aging. It is the reason to find new, effective and harmless hepatoprotectors. In the review is shown the data of hepatoprotective, immunoprotective and antiageing properties of liver polypeptide complex (Ventvil) and KEDA tetrapeptide (Lys-Glu-Asp-Ala, Livagen). In liver pathology experimental models (liver fibroid induration, acute and chronic hepatitis) in amimals and in vitro was shown high efficiency of Ventvil and KEDA peptide. Ventvil and KEDA peptide had concordant effects - normalized immune and antioxidant status, restored liver function during hepatitis. It was demonstrated, that maximal hepato- and immunoprotective effect of peptides verified in aging.
