姿势对某些血液成分可能有重要影响,当受检者由平卧位改为直立位时,可使健康人的血浆容量减少大约12%,从而有可能使蛋白质、脂蛋白和脂质的浓度增加。本文评价了体位对血清脂质,尤其对脂固醇比率[HDL-ch×100/LDL-ch+VLDL-ch]的影响。作者检查了41例年龄50岁的健康人,分别在平卧30分钟后和直立30分钟后从静脉采取血样,测定血清总胆固醇、高密度脂蛋白胆固醇(HDL-ch)和甘油三酯(TG)浓度,并计算LD-ch+VLDL-ch和HDL-oh×100/LDL-ch+VLDL-ch比率。结果发
Poses may have a significant effect on certain blood components, reducing the plasma capacity of healthy individuals by about 12% when the subject changes from the supine position to the upright position, thereby making it possible for the concentration of protein, lipoprotein and lipid increase. This article assesses the effect of body position on serum lipids, especially the ratio of [HDL-ch × 100 / LDL-ch + VLDL-ch]. The authors examined 41 healthy individuals, 50 years of age, taking blood samples from veins 30 minutes after supine and 30 minutes after upright, respectively, and measured serum total cholesterol, high-density lipoprotein cholesterol (HDL-ch) and triglyceride ) Concentration was calculated and the LD-ch + VLDL-ch and HDL-oh × 100 / LDL-ch + VLDL-ch ratios were calculated.
