Melanosomes were isolated from human and dog hairs and their Zn content was determined. The mean Zn concentrations, in mug Zn/g dry weight, were 687 (men's melanosomes), 641 (women's melanosomes) and 691 (dog melanosomes). These values rank melanosomes from pigmented keratinous structures among the structural elements with the highest Zn content. An interpretation of the possible causes of this accumulation was submitted. By means of the conversion factor between hair length and weight (determined at 0.004), it was estimated that daily Zn lossess via hair vary in the region of 19 mug. In detailed studies of Zn metabolism, excretion via pigmented keratinous structures ought not to be neglected.
从人发和狗毛中分离出黑素小体，并测定其锌含量。以每克干重含锌微克数计，锌的平均浓度分别为：687（男性黑素小体）、641（女性黑素小体）和691（狗黑素小体）。这些数值使黑素小体在含锌量最高的结构成分中，位列有色素的角质结构。文中对这种积累的可能原因进行了解释。通过毛发长度与重量之间的换算系数（测定值为0.004），估计通过毛发每日流失的锌量在19微克左右。在锌代谢的详细研究中，不应忽视通过有色素的角质结构的排泄。
