用Ｎ１５甘氨酸作示踪剂，对１２例慢性肾衰病人服百令胶囊１月，测定体蛋白代谢及治疗前后血氨基酸。结果：蛋白质合成速度和氨基氮利用率平均明显升高，血浆必需氨基酸：丝、缬、异亮、亮、酪、赖氨酸有明显升高，非必需氨基酸稍有升高。百令胶囊能促进体内蛋白质合成代谢及氨基酸利用，促进正氮平衡又能纠正慢性肾衰病人血浆必需氨基酸缺乏现象，改善营养情况，从而延缓肾衰进展。 Using N15glycine as a tracer, 12 patients with chronic renal failure were treated with Bailing capsules for 1 month to determine body protein metabolism and blood amino acids before and after treatment. Results: The protein synthesis rate and amino nitrogen utilization rate increased significantly on average. Plasma essential amino acids: silk, sputum, isobright, bright, lyesine, and lysine increased significantly, while non-essential amino acids increased slightly. Bailing capsules can promote protein synthesis and metabolism and amino acid utilization in the body, promote positive nitrogen balance and correct plasma deficiency amino acid deficiency in patients with chronic renal failure, improve nutrition, and delay the progression of renal failure.
