Abstract
1 Antipyrine plasma half-life and clearance rates were studied in 19 elderly patients shortly after admission to a geriatric ward and again 2 weeks after a course of dietary supplementation with Vitamins A, B complex, C and D. 2 Antipyrine half-life fell and clearance increased in the nine who had sub-clinical evidence of ascorbic acid deficiency. No correlation was found with other indices of nutritional status. 3 Vitamin supplementation in elderly people with no demonstrable deficiencies did not alter the metabolism of antipyrine.
摘要
- 对19名老年患者在入住老年病房后不久以及在接受维生素A、复合维生素B、维生素C和维生素D膳食补充疗程2周后，研究了安替比林的血浆半衰期和清除率。2. 在9名有亚临床维生素C缺乏证据的患者中，安替比林半衰期缩短，清除率增加。未发现与其他营养状况指标相关。3. 对无明显营养素缺乏的老年人补充维生素并未改变安替比林的代谢。
