2. Teorias(envelhecimento)
Muitas teorias foram propostas mas não
aceitas universalmente.
A teoria dos radicais livres proposta em
1954 mostrou que dietas ricas em
antioxidantes aumentavam a vida média
de animais de laboratório em 30 %.
Os RL abrangem reações ativadas pelo
meio ambiente, doenças e o processo
intrínseco do envelhecimento.

19. Age Decline of hGH
Somatopause may be defined as the age decline of hGH.
•Aging symptoms as wrinkles, gray hair, decreased energy
and sexual function, cardiovascular disease, increased
body fat and osteoporosis are a consequence of hGH drop.
•Clinical evidence shows that the replacement of hGH can
reverse the above symptoms and turn back the biological
clock.
•A marked difference between GH and other
hormones is the body production of hGH
right into old age ,while other hormones
diminish.The restauration of youthful levels
of HG may be the release from an
sequestered state.
