Previous studies have used myeloperoxidase (MPO) as an inflammatory marker to estimate the accumulation of neutrophils in inflamed regions.
The aim of this experimental study was to quantify the levels of MPO related to experimental periodontal disease in rats.
Periodontal disease was induced in a group of rats using placement of a ligature around molar teeth. A group of rats without ligature placement served as a control. Measurements were made on the 3(rd), 7(th), 15(th) and 30(th) day from baseline. Gingival tissues were taken for quantification of MPO levels by ELISA.
The rats with induced periodontal disease showed statistically higher MPO levels (p < 0.05) when compared to control rats. A significant increase in the levels of MPO released on days 7 and 30 was observed, with higher levels in the group with induced periodontitis.
The levels of MPO were found to be higher in rats with induced periodontal disease, confirming the hypothesis that MPO may serve as an inflammatory marker for periodontitis.
以往研究使用髓过氧化物酶(MPO)作为炎症标志物来评估炎症区域中性粒细胞的聚集情况。
本实验研究旨在量化与大鼠实验性牙周病相关的MPO水平。
通过在磨牙周围放置结扎丝在一组大鼠中诱发牙周病。一组未放置结扎丝的大鼠作为对照。从基线开始在第3、7、15和30天进行测量。采集牙龈组织,通过酶联免疫吸附测定法(ELISA)对MPO水平进行定量。
与对照大鼠相比,诱发牙周病的大鼠MPO水平在统计学上显著更高(p < 0.05)。观察到在第7天和第30天释放的MPO水平显著增加,诱发牙周炎组的水平更高。
发现诱发牙周病的大鼠中MPO水平更高,证实了MPO可能作为牙周炎炎症标志物的假设。
