Given the importance of oxidative stress associated to
aging, it would be interesting to assess the effect of oral supplementation
with antioxidant substances capable of diminishing oxidative aggression and
free radicals generation associated to this condition.
This study investigated the effects of AIN-93 M diet
supplemented either with 2 % of propolis, or with 4 % of a natural product
obtained from lyophilizate vegetables, selected by its antioxidant properties,
in senescent healthy Wistar rats fed ad libitum over 3 months.
Propolis supplementation leads to a lower level of glucose
and cholesterol concentrations together with a reduction in protein oxidation.
Plasma thiobarbituric acid-reactive substance levels were lower in the rats
consuming the natural vegetable product and propolis possibly due to its
antioxidant components, neutralizing the free radical produced, and thus
preventing cellular damage.
The results of the present study suggest a synergic effect
of overall propolis compounds reducing the oxidative stress and glucose and
cholesterol plasma levels associated with aging.
