To investigate the influence of linearly polarized near-infrared irradiation using the Super Lizer trade mark on deformability of human erythrocytes.
Not only low-powered laser but also linearly polarized near-infrared beams have some biostimulation effects on various tissues. There were some reports of erythrocyte deformability improved by low-powered He-Ne laser irradiation.
Human erythrocyte samples stored for three weeks were adjusted to 30% hematocrit. Erythrocyte deformability presented as the filter filtration rate was measured.
There was no difference of the filter filtration rate between control group without irradiation and the group of 125 mJ/cm(2) exposure level at a wavelength of 830 nm. However, the groups of 625 and 1,250 mJ/cm(2) exposure levels at a wavelength of 830 nm showed higher filter filtration rates compared to the control group.
Linearly polarized near-infrared irradiation in a range of 625-1,250 mJ/cm(2) exposure level at a wavelength of 830 nm improved deformability of human stored erythrocytes.
研究使用Super Lizer商标的线性偏振近红外照射对人红细胞变形性的影响。
低功率激光以及线性偏振近红外光束对各种组织均有一定的生物刺激作用。有报道称低功率氦氖激光照射可改善红细胞变形性。
将储存三周的人红细胞样本调整至血细胞比容为30%。测量以滤过率表示的红细胞变形性。
未照射的对照组与波长830nm、暴露水平为125mJ/cm²的照射组之间的滤过率无差异。然而,波长830nm、暴露水平为625和1250mJ/cm²的照射组与对照组相比,滤过率更高。
波长830nm、暴露水平在625 - 1250mJ/cm²范围内的线性偏振近红外照射可改善储存的人红细胞的变形性。
