本实验是低功率密度激光及其相干性和偏振性的生物作用研究。用波长为633毫微米,剂量为2.2焦耳/平方厘米,但分别为相干偏振、相干非偏振、非相干偏振和非相干非偏振四种光波幅照家兔实验性伤口,做了60只家兔的360个实验性伤口的实验。在观察伤口愈合速度的同时,分期分12批取1080个标本,每标本观察12项光镜指标。结果显示了所有这四种光都能促进伤口愈合,都使愈合提前3～4天以上,都能促进伤口内巨噬细胞胞浆中酯酶含量增加,都能促进上皮再生、附件再生和成纤维细胞再生及其各自细胞核内DNA含量增加。上述各指标与空白对照组比都具有统计学上的显著性差异,但在各实验组之间未见相干与非相干的差异,也未见偏振与非偏振的差异。
This experiment is a low power density laser and its coherence and polarization of the biological role of research. Six rabbits were irradiated with four light waves at a wavelength of 633 nm and a dose of 2.2 joules per square centimeter, respectively, but with four different light amplitudes: coherent, coherent, non-polarized, incoherent, and non-coherent, Experiment with 360 experimental wounds. While observing the wound healing rate, 1080 samples were taken in 12 batches, and 12 light microscopes were observed for each sample. The results showed that all these four light can promote wound healing, make the healing more than 3 to 4 days in advance, can promote the increase of esterase in macrophage cytoplasm of wound, can promote epithelial regeneration, attachment regeneration and Fibroblast regeneration and increased DNA content in their respective nuclei. There was a statistically significant difference between the above indexes and the blank control group, but there was no difference between coherence and non-coherence among the experimental groups, and no difference between polarization and non-polarization.
