  Comparing the obtained experimental data for the proton magnetic relaxation
with the microcalorimetric ones it is concluded that in the aqueous solution of
collagen + DNA at temperatures below 35oC a stable molecular complex
collagen-DNA is formed prohibiting the formation of the hydration cover of
collagen which is manifested by the almost two times decrease of hydration. At
temperatures (25-45)oC the disruption of complex and melting of triple helix of
collagen takes place. Starting from temperature 45oC up to 90oC hydration
values, calculated from experimental data on proton relaxation for solution
and, theoretical values calculated for the solution coincide speaking of the
fact that macromolecules in the solution are not practically interacting with
each other and not influencing the creation of each others hydration covers.
