| 摘 要： | 用Ｌｏｗｒｙ法测定冻干注射用胸腺肽中多肽含量时，由于冻干前所加赋形剂甘露醇的干扰，其测定结果明显偏高（Ｐ＜０．０００５）。本文经试验证明，用等量于检品中的甘露醇作空白对照，可以消除这种干扰。

| Abstract: | When the contents of polypeptide in lyophilized thymosin for injection are determined by Lowry method, the result shows that is obviously increased (p<0.0005) since it is added mannitol before the freeze drying. This paper confirms that the equivalent quantity of mannitol controlled with the one of the samples can eliminate the interference. |
