(ALT): The reference value is less than 50 units, which is the main item for diagnosing liver cell parenchymal damage, and its value is high.
Low is often parallel to the severity of the disease. ALT can be used for acute hepatitis, chronic hepatitis and liver cirrhosis.
Stand up. However, the lack of specificity of ALT can increase many liver diseases and extrahepatic diseases. In addition, alanine aminotransferase activity will also change.
The chemical transformation of liver is inconsistent with pathological changes, and some patients with severe liver injury do not have elevated ALT.
2. Normal liver function-aspartate aminotransferase (AST): the former is located in cytoplasm and the latter in cell line.
In the particles. The significance of elevated AST in the diagnosis of hepatitis is similar to that of ALT. Generally speaking, it is elevated.
The amplitude is not as good as ALT If AST value is higher than ALT, the degree of hepatocyte injury and necrosis is more serious.
. If the isoenzyme is determined, the significance will be even greater. Only ASTs will increase in mild liver injury, but it will increase in severe liver injury.
The ASTm has increased significantly. 3. Normal value of liver function-alkaline phosphatase (ALP): the normal participation value is
30-90u/L. It is composed of more than three isoenzymes, namely, liver type, intestine type (with little content) and placenta type.
(only seen in pregnant women in the middle and late stages), and some of them come from bones. Alkaline phosphatase is excreted through biliary tract. Therefore,
Liver diseases include excretory dysfunction, biliary tract diseases and bone diseases (such as osteosarcoma and metastatic bone).
Tumor) can increase ALP. 4. Normal liver function-glutamyltransferase (-GT): healthy
The level of -GT in human serum is very low (below 40 units), mainly from the liver, and a small amount from the kidney, pancreas and urine.
Intestinal production. -GT is inferior to ALT in reflecting hepatocyte necrosis damage, but it has a certain degree in differentiating jaundice.
Significance, poor intrahepatic excretion (intrahepatic obstruction) and extrahepatic obstruction (such as biliary obstruction) and liver
Sclerosis, toxic liver disease, fatty liver and liver tumor can all increase. 5, normal liver function-total
Protein (TP), albumin (a) and globulin (g): the normal value of TP is 60-80g /L, and the normal value of A is 40-.
55g /L, g is 20-30g /L, and A/G is 1. 5-2。 5: 1。 Chronic hepatitis and cirrhosis often occur.
Albumin decreased and globulin increased, which reversed the A/G ratio. 6, normal liver function-serum total
Bile red and direct bile red (Bc): jaundice occurs in liver disease, and TB and Bc can be increased to varying degrees.
The normal value TB is 2-20 μm ol/L, and Bc is less than 3. 4umol/L, such as Bc significantly increased, suggesting obstruction.
Jaundice. 7. Normal values of liver function-total cholesterol (Ch) and cholesterol ester (cbE): understandable.
The disorder of lipid metabolism in liver disease may increase in obstructive jaundice and fatty liver.
If the liver is seriously damaged, the total cholesterol and cholesterol esters can be reduced.
The treatment of abnormal liver function should be carried out according to the specific situation, and the causes of abnormal liver function are different.
The treatment of abnormal liver function is also different. If the patient with abnormal liver function has a history of liver disease, such as hepatitis B.
Sanyang, fatty liver, alcoholic hepatitis, liver cirrhosis, etc. Abnormal liver function and high transaminase.
It is possible that the liver disease has worsened, and it is necessary to check the liver and gallbladder B-ultrasound and liver fiber to understand the abnormal liver function.
Etiology, according to the cause of treatment. If the abnormal liver function is only manifested as high transaminase, the liver function will be improved.
Drinking alcohol, strenuous exercise, catching a cold and taking certain drugs before the examination can lead to
Transient transaminase is high. In this case, take a proper rest first and don't need treatment for the time being.
Check the liver function for a while. If the liver function returns to normal, there will be no problem. It should be noted that
The purpose is that the treatment of abnormal liver function needs to be determined according to the etiology, and can not simply reduce enzymes and jaundice.
Waiting for treatment will cover up the real cause and lead to the deterioration of liver disease. Clinically, it is most likely to cause liver disease.
Abnormal functions are hepatitis B, liver cirrhosis, hepatic ascites, alcoholic hepatitis, fatty liver and hepatic fibrosis.
Like liver disease. The following details how to treat abnormal liver function caused by various diseases.
