Human subjects were deprived of protein for 15 days, after which time hair from the scalp of each subject was plucked and examined. Both the bulb and the external root sheath showed morphological changes. This technique may therefore be useful in diagnosing proteincalorie malnutrition.
对人体受试者进行为期15天的蛋白质剥夺，之后拔取每位受试者头皮的毛发并进行检查。毛球和外根鞘均呈现出形态学变化。因此，该技术可能有助于诊断蛋白质 - 热量营养不良。
