Serum levels were determined in urban Chinese, Malays and Indians and in the forest-residing Orang Asli of age group 11 to 50. There was no difference in the IgM levels in the Chinese, Indians and Malays, but the serum IgG was elevated (p less than 0.05) in the Malays and the serum IgA level (p less than 0.01) in the Indians, when compared to the other two races. In contrast to the three other races there was a significant elevation of all three immunoglobulins in the Orang Asli. The mean immunoglobulin levels of the urban Malaysians are comparable to those reported for Caucasians residing in temperate countries. However, in the Orang Asli, the immunoglobulin levels were higher than observed for populations of the temperate regions but are comparable to the levels reported for several other populations of the tropical regions. Females had higher IgM levels than males in the Chinese, Indian and Malays but in the Orang Asli there was no sex difference in the immunoglobulin levels.
对年龄在11至50岁的中国城市居民、马来人、印度人以及居住在森林中的原住民奥朗阿斯利人的血清水平进行了测定。中国人、印度人和马来人的IgM水平没有差异，但与其他两个种族相比，马来人的血清IgG升高（p<0.05），印度人的血清IgA水平升高（p<0.01）。与其他三个种族不同，奥朗阿斯利人的所有三种免疫球蛋白均显著升高。城市马来西亚人的平均免疫球蛋白水平与居住在温带国家的白种人报告的水平相当。然而，奥朗阿斯利人的免疫球蛋白水平高于温带地区人群的观察值，但与热带地区其他一些人群报告的水平相当。在中国、印度和马来人群中，女性的IgM水平高于男性，但在奥朗阿斯利人中，免疫球蛋白水平没有性别差异。
