Pigment granules have been studied in macrophages of skin window preparations. These granules usually appeared blue with Romanowsky stains, and stained positively for melanin but negatively for iron. There were significantly more pigment granules per macrophage in sun-tanned individuals and in coloured subjects and in the latter, the granules were usually larger and darker. Presumably, the source of the melanin is damaged or degenerating pigment cells of the skin and reflects a normal in vivo phenomenon.
在皮肤窗制备物的巨噬细胞中对色素颗粒进行了研究。这些颗粒用罗曼诺夫斯基染色通常呈蓝色，对黑色素呈阳性染色，而对铁呈阴性染色。在晒黑的个体和有色人种的受试者中，每个巨噬细胞中的色素颗粒明显更多，并且在后者中，颗粒通常更大且颜色更深。推测，黑色素的来源是皮肤中受损或退化的色素细胞，反映了一种正常的体内现象。
