    • The present invention relates to a diagnostic agent for liver function, comprising a compound labelled with .sup.13 C at least at one specific position selected from the group consisting of the following (a) to (f):(a) galactose, glucose or xylose labelled with .sup.13 C at least at one specific position or a starch composed of glucose units labelled with .sup.13 C at least at one specific position;(b) a polar amino acid, heterocyclic amino acid, isoleucine or valine labelled with .sup.13 C at least at one specific position;(c) a carboxylic acid constituting the glycolytic pathway or the citric acid cycle, labelled with .sup.13 C at least at one specific position;(d) a fatty acid labelled with .sup.13 C at least at one specific position;(e) a glyceride labelled with .sup.13 C at least at one specific position; and(f) glycerol labelled with .sup.13 C at least at one specific position.According to the present invention, a diagnostic agent for liver function which imposes less physical burden on a subject, can give accurate test result immediately, and can be used safely without side effects is provided. The diagnostic agent of the invention is useful for evaluating the liver function of a subject at the time when the test is carried out.
    • 本发明涉及一种用于肝功能的诊断剂,其包含用13C标记的至少一个特定位置的化合物,所述化合物选自以下(a)至(f):(a)标记的半乳糖,葡萄糖或木糖 13C至少在一个特定位置或由至少在一个特定位置用13C标记的葡萄糖单元组成的淀粉; (b)至少在一个特定位置用13C标记的极性氨基酸,杂环氨基酸,异亮氨酸或缬氨酸; (c)构成糖酵解途径或柠檬酸循环的羧酸,至少在一个特定位置用13C标记; (d)至少在一个特定位置用13C标记的脂肪酸; (e)至少在一个特定位置用13C标记的甘油酯; 和(f)至少在一个特定位置用13℃标记的甘油。 根据本发明,对受试者施加较少体力负荷的肝功能诊断剂可以立即给出准确的测试结果,并且可以安全使用而没有副作用。 本发明的诊断剂可用于评估在进行测试时受试者的肝功能。

    • The present invention relates to a diagnostic agent for diabetes, comprising a compound labelled with 13C at least at one specific position selected from the group consisting of the following (a) to (g): (a) galactose, fructose or xylose labelled with 13C at least atone specific position, or a starch composed of glucose units labelled with 13C at least at one specific position; (b) an amino acid labelled with 13C at least at one specific position; (c) lactic acid or citric acid labelled with 13C at least at one specific position; (d) a fatty acid labelled with 13C at least at one specific position; (e) a glyceride labelled with 13C at least at one specific position; (f) glycerol labelled with 13C at least at one specific position; and (g) aminopyrin of which the dimethylamino group at position 4 is labelled with 13C, phenacetin of which the ethoxy group is labelled with 13C at position 1, or methacetin of which the methoxy group is labelled with 13C. According to the present invention, there is provided a diagnostic agent for diabetes which does not impose a heavy physical burden on a subject, can give accurate test results immediately and can be used safely without side effects. The diagnostic agent of the invention makes it possible to discriminate patients with diabetes from normal subjects even under circumstances where patients are easily missed.
    • 本发明涉及一种用于糖尿病的诊断剂,其包含用13C标记的至少一个特定位置的化合物,所述化合物选自以下(a)至(g):( a)用13C标记的半乳糖,果糖或木糖 至少在一个特定位置,或由至少在一个特定位置用13C标记的葡萄糖单元组成的淀粉;(b)用13C至少在一个特定位置标记的氨基酸;(c)用13C标记的乳酸或柠檬酸 至少在一个具体位置;(d)至少在一个特定位置用13C标记的脂肪酸;(e)至少在一个特定位置用13C标记的甘油酯;(f)用13C标记的至少一个特定的 位置; 和(g)其中第4位的二甲氨基用13C标记的氨基吡啶,其中乙氧基被1位13C标记的非那西丁或甲氧基用13C标记的美沙西丁。根据本发明, 提供了不对受试者施加沉重的身体负担的糖尿病诊断剂,可以立即给出准确的测试结果,并且可以安全使用而没有副作用。 本发明的诊断剂即使在容易错过患者的情况下也能够将糖尿病患者与正常人区分开来。
