健康雄性大鼠54只,随机分为不同激光功率的4个组和捆绑、空白对照组。大鼠捆绑于鼠台,每天用激光照射右“足三里”10min,第6天实验后,取空、回肠系膜铺片,醛品红—橙黄G染色,10×40倍光镜作镜检。结果发现,除40mW激光组出现抑制效应外,激光照射使肥大细胞数量升高,接近正常水平,肥大细胞脱颗粒率增加。此种变化尤以5mW和20mW激光作用最佳。激光照射“足三里”的作用,空肠优于回肠。 Fifty-four healthy male rats were randomly divided into 4 groups with different laser power and bundled and blank control groups. Rats were tied to a rat sera and irradiated with laser light for 10 minutes each day. After the sixth day of experiment, the animals were taken to empty, ileal mesangial slides, aldehyde magenta-orange G stain, and 10×40 light microscope for microscopic examination. The results showed that, except for the inhibition effect of the 40mW laser group, the laser irradiation increased the number of mast cells, approached normal levels, and increased the degranulation rate of mast cells. This change is particularly effective with 5mW and 20mW lasers. Laser irradiation “Zu Sanli” role, jejunum is better than ileum.
