用2—3二氨荃萘荧光法测定日本和美国健康妇女和患乳腺癌及良性乳腺疾病妇女的血硒浓度。日本健康妇女血晒浓度为0.285±0.33微克/毫升与以前报告的数值相似,日本患乳腺癌和良性乳腺疾病病人的血硒分别为0.195±0.057微克/毫升和0.200±0.45微克/毫升。乳腺癌复发的病人平均血硒为0.188±0.0611微克/毫升。美国加州圣地亚哥健康妇女的血硒浓度为0.18±0.024微克/毫升,患良性 Blood selenium concentrations in healthy women and women with breast cancer and benign breast diseases in Japan and the United States were determined using 2-3-diamino-quinoline fluorescence spectrometry. The blood concentration of Japanese healthy women was 0.285 ± 0.33 μg / ml. Similar to the previously reported values, selenium levels in Japanese patients with breast cancer and benign breast disease were 0.195 ± 0.057 μg / ml and 0.200 ± 0.45 μg / ml, respectively. The average serum selenium in patients with recurrent breast cancer was 0.188 ± 0.0611 μg / mL. Serum selenium concentrations in healthy women in San Diego, California, USA, were 0.18 ± 0.024 μg / mL with benign
