The oxidative burst of human blood cells in the presence of different metal materials was investigated using chemiluminescence assay. Commercial pure titanium (Ti), titanium alloy (Ti6Al4V), and stainless steel 316L (SS) in particulate form with <20 μm in size were used. The effect of particulate materials opsonisation on the upregulation of the respiratory burst production by blood cells was also assessed. The largest chemiluminescence response was achieved after simultaneous injection of the stimulants fMLP+PMA. Moreover, Ti and SS induced a greater inflammatory reaction compared to Ti6Al4V, since the respiratory burst mounted was higher for both materials after opsonisation treatment. These results suggest that in vitro chemiluminescence response and respiratory burst measurements proved to be composition and treatment dependent.
使用化学发光分析法研究了在不同金属材料存在下人体血细胞的氧化爆发。使用了尺寸小于20μm的颗粒形式的商业纯钛(Ti)、钛合金(Ti6Al4V)和不锈钢316L(SS)。还评估了颗粒材料调理作用对血细胞呼吸爆发产物上调的影响。同时注射刺激剂fMLP+PMA后实现了最大的化学发光响应。此外,与Ti6Al4V相比,Ti和SS诱导了更大的炎症反应,因为在调理作用处理后,这两种材料的呼吸爆发都更高。这些结果表明,体外化学发光响应和呼吸爆发测量结果证明取决于成分和处理方式。
