superoxide dismutase

Superoxide dismutase (SOD) is a natural scavenger of the important free radical-superoxide radical O2- in the body and is the main defense enzyme for free radical damage. With the continuous improvement and improvement of the SOD measurement method, its clinical application has become increasingly widespread. A large number of clinical data have confirmed that SOD is closely related to the physiological pathology of human body and the occurrence and development of various diseases. Basic Information Specialist classification: growth and development check classification: biochemical examination Applicable gender: whether men and women apply fasting: fasting Analysis results: Below normal: Viral myocarditis, childhood pneumonia, anemia, hemolytic disease, diabetes, rheumatoid arthritis, subarachnoid hemorrhage, heart transplantation, etc. Normal value: Superoxide dismutase: 242-620U/L Above normal: 1, elevated tumors, schizophrenia, hypertension, acute myocardial infarction. 2. Significantly increase liver cancer. negative: Positive: Tips: When measuring the activity of white blood cell SOD, the specimen to be tested cannot be hemolyzed, and too many red blood cells cannot be mixed into the isolated white blood cells. Normal value 1. Enzyme rate method (37 ° C) serum 242 ~ 620 U / L; red blood cells 5375 ~ 7795 μg / g · Hb. 2, pyrogallol method myocardium 300.3 ~ 406.3U / g; red blood cells 1567 ~ 2241U / g. 3, the United States anisidine method myocardium 1745 ~ 2231U / g; red blood cells 2906 ~ 4654U / g. Clinical significance 1, elevated tumors, schizophrenia, hypertension, acute myocardial infarction. 2. Significantly increase liver cancer. 3, reduce viral myocarditis, childhood pneumonia, anemia, hemolytic disease, diabetes, rheumatoid arthritis, subarachnoid hemorrhage, heart transplantation. Low results may be diseases: viral myocarditis, anemia, hemolytic anemia in children may result in high disease: liver cancer, acute myocardial infarction 1. The erythrocyte superoxide dismutase extract should be clear. If turbidity interferes with the enzyme activity, the result will decrease. 2. When the red blood cell SOD is measured, the experimental temperature is controlled at 22 to 25 ° C, and the enzyme activity is decreased by more than 25 ° C. 3. When measuring the activity of white blood cell SOD, the sample to be tested cannot be hemolyzed, and too many red blood cells cannot be mixed into the separated white blood cells. Inspection process It was determined by the enzyme rate method, the pyrogallol method, and the anisidine method. Not suitable for the crowd no. Adverse reactions and risks no.
