从光镜和电镜的组织病理学变化,初步观察了抗氧化剂β-胡萝卜素对被动吸烟所致小鼠慢性支气管炎(慢支)的影响。实验结果表明;喂β-胡萝卜素小鼠的慢支各种病理变化明显轻于单纯烟熏组(P<0.01),提示β-胡萝卜素对吸烟所致慢支的抗炎、抗损伤的保护作用。
The changes of histopathological changes in light and electron microscopy were studied. The effects of β-carotene, an antioxidant, on chronic bronchitis (chronic bronchitis) in mice induced by passive smoking were observed. The results showed that the pathological changes of chronic bronchitis mice fed with β-carotene were lighter than those of simple smoked groups (P <0.01), which indicated that β-carotene could prevent the chronic bronchitis from being anti-inflammatory and anti-inflammatory effect.
