Abstract

The free radical theory of aging is critically discussed. This review deals with the biological effects of free radicals during the aging process, the relationship between aging and diseases and how they both may be affected by free radicals, and the effects of free radicals on the human lifespan. The paper emphasizes aspects which require additional investigation.

Résumé

La théorie des radicaux libres du vieillissement est très critiquée. Ce compte-rendu traite des effets biologiques des radicaux libres au cours du processus du vieillissement, de la relation entre le vieillissement et la maladie (comment ces deux concepts peuvent être affectés par les radicaux libres) et des effets des radicaux libres tout au long du cycle de vie. Cet article met en relief des aspects qui demandent une étude plus approfondie.
