Ultrasonic cleaning is to remove stones, smoke stains and refreshments from the teeth by high-frequency oscillation of the ultrasound. It prevents bleeding gums or loose teeth and helps treat oral diseases such as periodontitis. The effect is obvious and it will not harm oral health.
The home red and blue light treatment instrument is a kind of laser treatment instrument. It irradiates the skin with red and blue light with high purity and high power density, and finally plays a role in treatment and whitening, which has a significant effect on skin diseases.
Analytical balance is a weighing tool specially suitable for chemical analysis. The accuracy is determined according to the accuracy of chemical analysis. The accuracy of analytical balances is generally high, and the requirements on the environment are higher.
Pulmonary function test is one of the necessary checks of the respiratory system. It can check the lungs and respiratory system diseases at an early stage. The common instrument for pulmonary function test is the pulmonary function meter. Next, let's take a look. Which brand of pulmonary function meter is good?
The price of blood glucose test strips is a few dollars apiece. The prices of different brands are different. Friends who want to use them can go to the local regular pharmacy for consultation and purchase.
Medical cold compresses can be used as masks. There is no difference in the appearance of medical cold compresses and ordinary cold compresses. The methods of use are similar, but they differ in terms of approval number, quality standard, main ingredients, efficacy and safety.
The specific reason for not urinating after removing the urinary tube needs to be combined with the previous condition, such as urinary catheterization due to dysuria similar to that of prostatic hyperplasia or neurological disease. Completely cured, the urinary can't urinate normally after removing the urinary tube, which is normal (the etiology is not treated). At this time, it is necessary to indwell the catheter to drain urine.
84 disinfectant is a chlorine-containing disinfectant. Its composition is more special. It is a compound chlorine-containing disinfectant. Because 84 disinfectant is usually used to improve its stability, in order to enhance its effect, some auxiliary agents are added inside. Ingredients.
lB medium is the name of a medium, which is generally used to pre-cultivate strains in biochemical molecular experiments, so that the strains are multiplied to meet the requirements for use. The cultured bacteria are generally engineered bacteria that cannot be individually survived and expanded in the external environment.
The coip kit can efficiently perform antigen immunoprecipitation and co-immunoprecipitation experiments with less than 10 μg antibody. First, a specific antibody is added to the sample to form an immune complex with the target antigen, and then it is bound to the protein G resin. After removing unbound material by rinsing, the immune complexes are eluted from the protein G resin with a low pH eluent.
In addition to hyperglycemia, post-diabetes patients often have complications such as blindness, renal failure, stroke, and cerebral hemorrhage. To prevent the above symptoms, it is necessary to measure cholesterol ratio at any time.
The principle is that p-nitrophenol phosphate is used as a substrate, and 2-amino-2-methyl-1-propanol or diethanolamine is used as a phosphate acyl acceptor. Under alkaline environment, ALP catalyzes the hydrolysis of 4-NPP to produce free p-nitrophenol, which turns to yellow in alkaline solution. ALP activity units were calculated based on the rate of increase in absorbance at 405 nm.
Macrolide antibiotics are preferred for treatment, such as erythromycin, azithromycin, roxithromycin, clarithromycin, etc. Mild infections are treated with oral dosage forms, such as fluoroquinolones, such as levofloxacin, gatifloxacin, mo Xisha star and so on. In case of drug-resistant infections, tetracyclines are also available.
With the development of the economy, people attach great importance to their health. One of the tests can help people stay away from major diseases, but its price is very high. This test is the flow of genetic testing. Next, let ’s understand , Genetic testing process?
Genetic testing is divided into biochemical testing, chromosome analysis and DNA analysis. Biochemical testing is the use of chemical means to check for the presence of related proteins or substances, and to determine whether there are genetic defects. Chromosome analysis directly detects abnormalities in the number and structure of chromosomes and is usually used to diagnose abnormalities in the fetus. And DNA analysis is mainly used to identify genetic diseases caused by abnormal single genes, such as Huntington's disease. Cells analyzed by DNA are mainly from blood or fetal cells.
The essence of immunoglobulin is protein, which is one of the immunoactive molecules, which is often extracted from animal blood.
Immunoglobulin E is high and is called allergic constitution. Allergies are generally prone to allergic reactions or allergic diseases, and no cause can be found. If you suffer from eczema, urticaria, some suffer from allergic asthma, and some are particularly sensitive to certain drugs, drug-induced dermatitis, or even exfoliative dermatitis can occur.
Immunoglobulins can be divided into antibodies and membrane immunoglobulins. Antibodies mainly exist in serum, but also can be found in other body fluids and exocrine fluids. The main function is to specifically bind antigens in the body. After the antibodies bind to antigens, they can directly exert their effects. Virus neutralizing antibodies can prevent the virus from infecting target cells and secrete them. IgA can inhibit the adhesion of bacteria to host cells.
Human immunoglobulin was originally called human blood gamma globulin, now it is about 200 yuan. Currently, the price of 2.5g (5%, 50ml) / bottle of intravenously injected human immunoglobulin (pH4) on the market is 210 yuan / box. It is suitable for the prevention of infectious hepatitis; prevention of viral diseases and infections such as measles; treatment of congenital gamma globulin deficiency; combined use with antibiotics can improve the efficacy of some serious bacterial and viral infections.
Globulin has an immune effect. When the immune system encounters foreign invaders, it will show different amounts of globulin according to different invaders. If the invaders are relatively difficult to destroy, the immune system is stimulating It will produce more globulin after the lymph, and it will not stop until the invader is eliminated by globulin.
