Abstract
To compare the Paraoxonase 1 (PON1) activity and phenotype distribution between lumbar disc herniation (LDH) patients and healthy individuals. This research included 40 LDH patients and 42 healthy individuals. Spectrophotometric assays were performed to determine the serum PON1 and arylesterase activities. The PON1 ratio, which represents the salt-stimulated PON/ arylesterase level, demonstrated a trimodal distribution. This ratio was applied to identify the different phenotypes; QQ, QR, and RR of each subject. The LDH patients had lower PON1 activity than the healthy individuals (p < 0.05). LDH patients had a statistically significant QQ phenotype compared to the healthy subjects (p < 0.05). LDH patients had statistically lower PON1 activity, suggesting that the low PON1 activity and PON1 QQ phenotype may be a risk factor for LDH occurrence.
