Viral hepatitis G is an infectious disease with the parenteral mechanism of infection (mainly with blood transfusions). The virus of hepatitis G (HGV) is classified as the Flaviviridae family.
Heparin is a sulfated polysaccharide, synthesized in mast cells, does not penetrate the placenta. A lot of it is found in the liver and lungs. Turns antithrombin III into an immediate anticoagulant. With fibrinogen, plasmin and adrenaline forms complexes possessing anticoagulant and fibrinolytic action.
The system of hemostasis is a set of functional-morphological and biochemical mechanisms ensuring the preservation of the liquid state of the blood, preventing and stopping bleeding, and the integrity of the blood vessels.
Hemoglobin - the main component of erythrocytes, is a complex protein, consisting of heme and globin. The main function of hemoglobin is to transfer oxygen from the lungs to tissues, as well as to remove carbon dioxide from the body and regulate CBS.
Hematocrit - the volume fraction of erythrocytes in whole blood (the ratio of the volume of erythrocytes and plasma). The amount of hematocrit depends on the number and volume of red blood cells.
The most widely used serological method for the diagnosis of Helicobacter pylori is ELISA. The method is non-invasive and indirect: in the patient's blood, antibodies to Helicobacter pylori, attributed to IgA, IgM and (most often) IgG are determined.
The diagnostic sensitivity of PCR for detecting Helicobacter pylori in biopsy specimens of the gastric mucosa is 88-95.4%, specificity is 100%; in coprofiltrates - 61.4-93.7% and 100%, respectively.
Haptoglobin (Hp) is a blood plasma glycoprotein that specifically binds hemoglobin. There are three hereditary phenotypes of haptoglobin: Hp 1-1, 2-1, 2-2. The first form is a monomer with a molecular weight of 85,000, the other two are polymers with a varying but much larger mass.
For serological diagnosis of diseases caused by stick influenza, agglutination and precipitation reactions are used. Determination of antibodies to hemophilic rod in serum is a retrospective method of diagnosing the disease, since it is necessary to examine serum in the first week of the disease and after 10-14 days.
