Active oxygen has a strong relationship to aging.
It is said the living organisms are influenced by active oxygen, which increases the amount of the cell membrane of the lipid peroxide and decreases the fluidity of the cell membrane with age, causing the organisms to lose flexibility in the cell membrane as they grow old.
To examine whether the aging process is controlled even a little by low dose irradiation, healthy mice at various weeks of age irradiated with low doses of radiation.
We measured the manner in which the following items changed.
(1) Amount of lipid peroxide
(2) Fluidity of the membrane
(3) Amount of enzyme (SOD) that eliminates active oxygen
As a result, we confirmed that young mice seven weeks of age had the following relationship to mice at 65 weeks of age (corresponding to humans of about age 50-60):
(1) The amount of the lipid peroxide is large
(2) Membrane liquidity is low
(3) The amount of SOD is small
However, when we irradiated mice at 65 weeks of age with low dose radiation of about 50cGy, we found that characteristics (1) - (3) above improved significantly, approaches the level of the young mice.
