Changes in the activity of serum gamma-glutamyl transpeptidase (gamma-GTP) and the percentage of the gamma-GTP fraction in healthy young men given a high carbohydrate diet (480-636 g/day, 80% of the total energy) for 21 days were examined. Serum total gamma-GTP activity showed no significant change in four healthy young volunteers who received high carbohydrate diet for 21 days. However, the percentage of the gamma-GTP (1) fraction increased significantly (P less than 0.01) from the basal level of 55.6 +/- 4.0% to 67.6 +/- 0.9% on day 10, and then decreased to 58.4 +/- 1.4% on day 21. When the experimental diet was replaced by usual diet, the percentage of the gamma-GTP (1) fraction returned to the same level as before the experiment. It is concluded from the results that the nutrient intake affects the percentage of gamma-GTP (1), but not the total serum gamma-GTP activity.
研究了给予高碳水化合物饮食(480 - 636克/天,占总能量的80%)21天的健康年轻男性血清γ-谷氨酰转肽酶(γ-GTP)活性及γ-GTP组分百分比的变化。在接受高碳水化合物饮食21天的4名健康年轻志愿者中,血清总γ-GTP活性无显著变化。然而,γ-GTP(1)组分的百分比从基础水平的55.6±4.0%在第10天显著增加(P<0.01)至67.6±0.9%,然后在第21天降至58.4±1.4%。当将实验饮食替换为常规饮食时,γ-GTP(1)组分的百分比恢复到实验前的相同水平。从结果得出结论,营养摄入影响γ-GTP(1)的百分比,但不影响血清总γ-GTP活性。
