Plasma and urinary selenium were determined among vegans, lactovegetarians and several groups of omnivorous subjects, using gas-liquid chromatography. Plasma Se was lower among lactovegetarians (0.80 (SD 0.18) mumol/l) than in the other groups (0.98 (SD 0.15) mumol/l). This was not related to Se intake, since the vegans had a lower and the lactovegetarians a higher intake of Se than omnivorous subjects in Sweden. Urinary Se was 0.36 (SD 0.10) mumol/d for controls, 0.17 (SD 0.10) mumol/d for vegans and 0.16 (SD 0.07) mumol/d for lactovegetarians. No relation between dietary Se and urinary Se was observed. Among vegetarians, plasma Se and urinary Se were correlated (r 0.51; P less than 0.05).
采用气液色谱法测定了纯素食者、乳类素食者和几组杂食者的血浆和尿液中的硒含量。乳类素食者的血浆硒含量（0.80（标准差0.18）μmol/L）低于其他组（0.98（标准差0.15）μmol/L）。这与硒摄入量无关，因为在瑞典，纯素食者的硒摄入量低于杂食者，而乳类素食者的硒摄入量高于杂食者。对照组的尿硒为0.36（标准差0.10）μmol/d，纯素食者为0.17（标准差0.10）μmol/d，乳类素食者为0.16（标准差0.07）μmol/d。未观察到膳食硒与尿硒之间的关系。在素食者中，血浆硒和尿硒呈正相关（r=0.51；P<0.05）。
