丙氨酸氨基转移酶(ALT)广泛存在于人体各种组织器官、肌肉、骨骼中。ALT属细胞内酶,细胞内外有巨大的浓度差,正常时血清中活性很低[1]。ALT主要存在于肝细胞浆内,细胞内浓度高于血清中1000倍~3000倍。只要有1%的肝细胞被破坏,就可以使血清酶增高一倍。因此,ALT被世界卫生组织推荐为肝功能损害最敏感的检测指标。ALT测定是高校体检必检项目之一,现将龙游县2006年-2013年15417例高校体检学生ALT检测结果报道如下:1对象与方法
Alanine aminotransferase (ALT) is widely found in various tissues and organs, muscles and bones of the human body. ALT is a cell enzyme, a huge concentration difference inside and outside the cell, the normal serum activity is very low [1]. ALT is mainly present in the cytoplasm of liver cells, the intracellular concentration higher than 1000 times to 3000 times. As long as 1% of the liver cells are destroyed, you can double the serum enzyme. Therefore, ALT was recommended by the World Health Organization as the most sensitive detection of liver damage indicators. ALT test is one of the items of university medical examination, now Longyou County, 2006 - 2013 15417 cases of college students ALT test results reported as follows: 1 objects and methods
