牛磺酸对损伤的心肌肌膜ATPase活性影响的研究

本研究以异丙肾上腺素（Ｉｓｏｐｒｏｔｅｒｎｏｌ，Ｉｓｏ．）诱导的大鼠心肌损伤为模型，观察牛磺酸（Ｔａｕｒｉｎｅ，Ｔａｕ）对损伤心肌肌膜上Ｎ＿ａ￣＋—Ｋ＿－￣＋ＡＴＰａｓｅ、Ｃ＿ａ￣（２＋）－ＡＴＰａｓｅ、Ｍ＿ｇ￣（２＋）ＡＴＰＡＳＥ活性的影响。按Ｄａｈａｌｌａ方法分离及鉴定心肌肌膜同时分别测定三种ＡＴＰａｓｅ活性，结果：Ｉｓｏ组，与Ｔａｕ＋Ｉｓｏ组的三种ＡＴＰａｓｅ活性明显低于对照组与Ｔａｕ组，且同时Ｔａｕ＋Ｉｓｏ组明显高于Ｉｓｏ组但对照组与Ｔａｕ组之间差别无显著性。结果提示：牛磺酸能提高异丙肾上腺素诱导心肌损伤的心肌膜ＡＴＰａｓｅ活性，可能通过其保护心肌肌膜的结构及功能而实现的。

Study on Desalination of Cystine Mother Liquor by Electrodialysis

There were 17 kinds of amino acid in mother liquor by acidizing pighair and extracting cystine. In this paper, a high efficient ion-exchange membrance(HF-1 and HF-2) prepared by radoilysis was used and mother liquor was desalted using electrodialysis. This technique has been running for nearly one year with desalination efficiency higher than 95 percent and the Content of amino acids necessary for people more than 20 percent of total amino acids.
