局部振动作业工人对血脂和血黏度的影响

目的探讨局部振动对血脂、血黏度等指标的影响.方法检测暴露组和对照组工人的血胆固醇(TC)、甘油三酯(TG)、高密度脂蛋白(HDL)、低密度脂蛋白(LDL)、血黏度、载脂蛋白(Apo)、红细胞(RBC)、血小板(PLT)、平均红细胞容量(MCV)、餐后血糖(PBS)、血清蛋白.比较两组间均值与异常率的差异.结果暴露组TG[(1.01±0.85)mmol/L]、TC[(3.25±0.61)mmol/L]、HDL[(1.14±0.20)mmol/L]比对照组[分别为(1.89±1.47)、(3.87±0.82)、(1.22±0.26)mmol/L]明显减低,差异有显著性(P＜0.01、P＜0.05);Apo-A亦明显减低[分别为(1.13±0.29)、(1.23±0.16)g/L],差异有显著性(P＜0.01);血黏度明显增高[分别为(2.76±0.42)、(2.54±0.33)mpa@s],差异有显著性(P＜0.01).暴露组与对照组Apo-A异常率分别是23.30%、4.50%,差异有显著性(P＜0.01).结论局部振动可使作业工人血脂降低、血黏度增加并引起其他血液指标变化.

The effect of local vibration on blood-lipids and whole blood viscosity

OBJECTIVE: To study the effects of local vibration on blood-lipids and whole blood viscosity. METHODS: The total cholesterol (TC), triglyceride (TG), high density lipoprotein (HDL), low density lipoprotein (LDL), whole blood viscosity, apolipoprotein (Apo-), red blood cell (RBC), platelet (PLT), mean corpuscular volume (MCV), serum-protein, postprandial blood sugar (PBS), and serum-protein of experimental and control workers were detected. The difference of the means and abnormal rates of two groups were compared. RESULTS: The means of TG, TC, HDL in exposed group [(1.01 +/- 0.85), (3.25 +/- 0.61), (1.14 +/- 0.20) mmol/L respectively] were significantly lower than that of control group [(1.89 +/- 1.47), (3.87 +/- 0.82), (1.22 +/- 0.26) mmol/L, respectively, P < 0.01 or P < 0.05]. Apo-A was also decreased [(1.13 +/- 0.29) g/L vs (1.23 +/- 0.16) g/L, P < 0.01]. The mean of whole blood viscosity were significantly increased in exposed group [(2.76 +/- 0.42) mPa.s vs (2.54 +/- 0.33) mPa.s, P < 0.01]. The abnormal rate of Apo-A was significantly higher in exposed group (23.30%) than that in control (4.50%, P < 0.01). CONCLUSION: Local vibration may induce decrease in blood lipids, increase in blood viscosity and changes in some other blood parameters.
