A rapid microspectrophotometric method was used to measure zinc concentrations in plasma and erythrocytes. A circadian variation in plasma zinc related to the ingestion of food was observed. Fasting plasma zinc concentrations were low in 20 out of 23 paraplegic patients with pressure sores, indicating that oral zinc supplementation may be expected to accelerate healing in such patients. Erythrocyte zinc levels did not differ between different groups of subjects and exhibited no circadian rhythm.
采用快速显微分光光度法测定血浆和红细胞中的锌浓度。观察到血浆锌与食物摄入有关的昼夜变化。23例患有压疮的截瘫患者中有20例空腹血浆锌浓度较低,这表明口服补锌有望加速此类患者的伤口愈合。不同组别的受试者之间红细胞锌水平无差异,且未表现出昼夜节律。
