The effects of different concentrations (10-5 M, 10-4 M. 10-3 M) of Cu2+ on growth, antioxidant enzyme activity and malondialdehyde (MDA) content were investigated in hydroponically grown Allium sativum L. The results indicated that the growth of garlic seedlings was not inhibited under treatment with 10-5 M Cu2+. Garlic seedlings exposed to 10-4 M and 10-3 M Cu2+ exhibited significant growth reduction. With increasing Cu2+ concentration and treatment time, superoxide dismutase (SOD) activity increased in leaves and roots, and peroxidase (POD) activity increased in leaves. In roots of plants exposed to 10-4 M and 10-3 M Cu2+, POD activity increased within 9 d and then dropped, but was still higher than in the control at the end of the experiment. Catalase (CAT) activity increased in seedlings grown at 10-5 M and l0-4 M, whereas a highly toxic level of Cu2+ (10-3 M) markedly inhibited CAT activity. SOD and POD activity were higher in roots than in leaves, whereas CAT activity was higher in leaves than in roots under both control and Cu2+ treatments. There was no obvious effect on MDA content in the seedlings treated with 10-5 M Cu2+; at 10-4 M and 10-3 M Cu2+ it increased. The mechanisms of Cu2+ toxicity and Cu2+ tolerance in garlic are briefly discussed.

The study was designed to assess the antioxidant defense mechanisms, either enzymatic or non-enzymatic, in a group of sixteen centenarians (one male and fifteen female subjects aged 101 to 105 years) living in the Upper Silesia district (Poland) in order to evaluate the potential role of antioxidant defenses in human longevity. The results of our preliminary study showed that in comparison with young healthy female adults the centenarians had significantly higher red blood cell glutathione reductase and catalase activities and higher, although insignificantly, serum vitamin E level.

Cardiovascular ageing is associated with an increase in cardiac susceptibility to ischaemia and reperfusion and production of reactive oxygen species has been suspected to be responsible for this age-associated particular vulnerability. To determine whether administration of antioxidant treatment could afford some protection against ischaemia and reperfusion during aging, isolated perfused hearts from adult and senescent rats were submitted to normoxia (180 min), prolonged low-flow ischaemia (15% of initial coronary flow;180 min) or low-flow ischaemia/reperfusion (45 min/30 min), without or with antioxidant enzymes (superoxide dismutase+catalase; 50IU/ml). Contractile function and coronary perfusion were measured and protein oxidation was quantitated in left ventricle after normoxia, ischaemia and ischaemia/reperfusion. Protein oxidation was higher in senescent than in adult hearts after ischaemia-reperfusion, in contrast to prolonged ischaemia. During prolonged ischaemia, antioxidant treatment prevented coronary vasoconstriction at both ages and delayed contractile dysfunction in senescent hearts but did not limit protein oxidation. During reperfusion, antioxidant treatment prevented coronary vasoconstriction and protein oxidation at both ages and considerably improved recovery of contractile function in senescent hearts. In conclusion, antioxidant treatment fully protects the senescent heart against ischaemia/reperfusion but not against prolonged ischaemia injury, indicating that oxidative stress plays a central role in the age-associated vulnerability to ischaemia-reperfusion.
