检测871例健康吸烟者(简称吸烟组)和348例健康非吸烟者(简称非吸烟组)血浆维生素C(P-VC)、维生素E(P-VE)、β-胡萝卜素(P-β-CAR)含量的结果表明,吸烟组的P-VC、P-VE、P-β-CAR平均含量皆显著低于非吸烟组之值(P<0.001)。65例相同年龄吸烟者的P-VC、P-VE、P-β-CAR含量均随吸烟史及吸烟量的增加而降低,并均呈一定程度的直线相关(P<0.0001);检测结果提示吸烟可能导致体内的氧化和抗氧化平衡失调。
The plasma levels of vitamin C (P-VC), vitamin E (P-VE) and β-carotene (P-β-thalassemia) in 871 healthy smokers and 348 healthy nonsmokers were measured. CAR) showed that the average levels of P-VC, P-VE and P-β-CAR in smoking group were significantly lower than those in non-smoking group (P <0.001). The levels of P-VC, P-VE and P-β-CAR in 65 smokers of the same age decreased with the increase of smoking history and smoking history, and all showed a certain degree of linear correlation (P <0.0001) Smoking can cause imbalances in the body’s oxidation and antioxidant balance.
