| Research Abstract |
Objective. The aim of this study is to investigate a possible association between the transitional metals from environment/lifestyle and oxidative stress of patients with ALS in the K (Kozagawa/Kushimoto) area. Methods. Metal contents of the drinking water, serum and hair of patients with ALS and residents in this area were measured. Results. We found that the Ca content in the drinking water is low and that the serum levels of Ca and Zn in the residents and patients with ALS in this area were significantly lower, while the oxidative stress markers were significantly higher, than those of the controls. The Mn and V contents of scalp hair from the patients with ALS (n = 7) were significantly higher than those of controls (p < 0.05). The changes of lifestyle including westernization of eating habits were found in this area by the questionnaire. These changes might play a role in decreasing oxidative stress. Conclusions. We suggest that the low levels of Ca and Zn are possibly associated with an ncrease in oxidative stress in patients with ALS in this area, although the causative relationship is not clear. This is a cross-sectional study, and a prospective study is needed in the future.
