Decrease in Serum Amyloid a Protein Levels Following Three-month Stays in Negatively Charged Particle-dominant Indoor Air Conditions / 生物医学与环境科学（英文）

ABSTRACT

<p><b>OBJECTIVE</b>The changes in serum adipokines and cytokines related to oxidative stress were examined during 3 months 'Off to On' and 'On to Off' periods using negatively charged particle-dominant indoor air conditions (NCPDIAC).</p><p><b>METHODS</b>Seven volunteers participated in the study, which included 'OFF to 3 months ON' periods (ON trials) for a total of 16 times, and 'ON to 3 months OFF' (OFF trials) periods for a total of 13 times.</p><p><b>RESULTS</b>With the exception of one case, serum amyloid A (SAA) levels decreased significantly during the ON trials.</p><p><b>CONCLUSION</b>Considering that SAA is an acute phase reactive protein such as C reactive protein (CRP), this observed decrease might indicate the prevention of cardiovascular and atherosclerotic changes, since an increase in high-sensitive CRP is associated with the subsequent detection of these events.</p>
