Electron microscopy of unstained, fresh air-dried spreads of plucked human hair bulbs revealed relatively well preserved melanocytes and dense storage granules of melanin. Energy dispersive X-ray microanalysis of melanosomes and premelanosomes from black facial hair bulbs disclosed high peaks for potassium and sulfur, intermediate peaks for magnesium and calcium, and low but distinct ones for phosphorus and chlorine. No peaks for magnesium were found in the central portion of mature melanosomes, but at their edges and in premelanosomes conspicuous peaks for this element were obtained.
对拔下的人毛囊进行未染色、新鲜空气干燥涂片的电子显微镜检查显示，黑素细胞保存相对完好，且有密集的黑色素储存颗粒。对黑色面部毛囊的黑素小体和前黑素小体进行能量色散X射线微分析发现，钾和硫的峰值较高，镁和钙的峰值中等，磷和氯的峰值较低但明显。在成熟黑素小体的中心部分未发现镁的峰值，但在其边缘和前黑素小体中获得了该元素明显的峰值。
