요중 malondialdehyde의 정도와 냉증의 연관성에 대한 후향적 단면연구

Abstract

Objectives: This study aims to research correlation of the malondialdehyde level in urinalysis with cold hypersensitivity. Methods: We studied 128 patients visiting <TEX>${\bigcirc}{\bigcirc}$</TEX> Korean Hospital from March, 2013 to May, 2013. The subjects were categorized into two groups: cold hypersensitivity group (n=46) and control group (n=79). Patients in cold hypersensitivity group had been stressed because of severe cold hypersensitivity. First, We investigated the difference of the level of malondialdehyde between two groups. In addition, temperature of the two points, ST32 and LR3, was measured by using Digital Infrared Thermal Imaging (DITI) to find out whether the extent of cold hypersensitivity is related to the level of malondialdehyde. Results: There is no different characteristics between two groups. The average of malondialdehyde in cold hypersensitivity group (<TEX>$1613.15{\pm}1260.71$</TEX>) is significantly higher than in control group (<TEX>$1170.01{\pm}1015.66$</TEX>)(p=0.04). But there is no correlation between level of malondialdehyde and the extent of cold hypersensitivity (r=-0.22, p=0.13). Conclusions: Although the level of malondialdehyde in cold hypersensitivity group is higher than in control group, there is no significant correlation between level of malondialdehyde and the extent of cold hypersensitivity.
