【摘要】 本研究的目的是收集16天卧床对中国受试者钙、磷、氮影响的数据。受试者是5名健康成年男子。实验中观察到,卧床期钙、磷、氮平衡都是负的,平均总净丧失量分别为每人1.73、3.23、40.74g,平均每月钙丧失量约占总体钙的0.3%。同时还观察到,卧床期尿钙和尿羟脯氨酸排出量较对照值显著增加。在卧床期末,血清碱性磷酸酶活性较对照值显著减低而血尿素氮浓度较对照值显著增加。实验证明,16天卧床导致骨质和肌肉丧失。更多还原

【Abstract】 The objective of this study was to collect data on the effects of a16-day bedrest on the calcium,phosphorus and nitrogen balances inChinese subjects.The subjects were five healthy male adults.It wasobserved that during bedrest calcium,phosphorus and nitrogen bal-ances were negative,and mean total net losses were 1.73,3.32 and40.74 g respectively for each person,and the amount of calcium losswas about 0.3% of the total body calcium per month.It was alsoobserved that during the bedrest urinary calcium excretion and urinaryhydroxyproline excretion were significantly higher than the controlvalues.It was proven that the 16-day bedrest resulted in bone andmuscle losses.更多还原
