| Summary: | We examined association between the changes in blood oxidative stress level/activity and the
changes in memory performance in postmenopausal women receiving Tualang honey (TH). The verbal learning
and memory performances of thirty nine postmenopausal women were assessed using the Malay version of the
Auditory Verbal Learning Test (MVAVLT) and their oxidative stress levels/activities were determined using
commercially available kits before and 16 weeks after TH supplementation. The plasma glutathione peroxidase
(GPx) and catalase (CAT) activities were considerably increased but the 4-hydroxynonenal (4-HNE) level was
notably decreased after 16 weeks of TH supplementation. There were positive correlations between the changes
in plasma GPx and the changes in trial A6 scores (r = 0.48, P < 0.05) and between the changes in plasma CAT
and the changes in recognition score (r = 0.32, P < 0.05). TH supplementation for 16 weeks reduced blood
oxidative stress but most of the changes in blood oxidative stress level/activity were not significantly correlated
with the changes in memory performance. |
