The "sebum" secretion was evaluated in caucasian, black, yellow and mullato people of different ages by the osmic acid technique utilizing a semi-quantitative scale of score ranging from 0 to 9 points. The results have shown: 1) there is significant difference between to "sebum" secretion (CL = casual level or SER = sebum excretion rate) of males and females greater than or equal to 60 years old, regardless the race; 2) males and females of each age subgroup have shown no difference of "sebum" secretion (NC or TRE) regardless the race; 3) male volunteers of different races have shown no difference secretion regardless the age and the race. On the other hand, females greater than or equal to 60 years old, regardless the race have shown low "sebum" secretion tham of 15-19 and 50-59 years old; 4) no circadian, ultradian and seasonal rhythm of "sebum" secretion were verified.
采用从0到9分的半定量评分标准，通过锇酸技术对不同年龄的白种人、黑人、黄种人和混血人种的“皮脂”分泌情况进行了评估。结果显示：1）无论种族如何，60岁及以上男性和女性的“皮脂”分泌（CL = 偶然水平或SER = 皮脂排泄率）之间存在显著差异；2）每个年龄亚组的男性和女性，无论种族，其“皮脂”分泌（NC或TRE）均无差异；3）不同种族的男性志愿者，无论年龄和种族，其分泌情况均无差异。另一方面，60岁及以上的女性，无论种族，其“皮脂”分泌均低于15 - 19岁和50 - 59岁的女性；4）未证实“皮脂”分泌存在昼夜、超昼夜和季节性节律。
