Viral Apocalypse is on the brink, warns chief medical officer of Great Britain - Sally Davis. A growing number of drug-resistant diseases can provoke "apocalyptic scenario" comparable to the catastrophic consequences of the worst, and a large-scale disaster.
Sally Davies said the risk that in 20 years people admitted to hospital for the easiest diseases - Urut from simple infection caused are antibiotic-resistant viruses.
She told deputies about the reality of the threat the loss of millions of citizens from simple infections that are resistant to antibiotics. The threat is so serious Read more [...]
Respiratory viral infections - Big group infectious disease affecting the respiratory tract, different depth and extent (pharyngitis, tracheitis, bronchitis, bronchiolitis, interstitial pneumonia). These diseases are accompanied by more or less severe febrile reactions and symptoms of toxicity. Until 1953 the disease in this group had different names: febrile catarrh, seasonal catarrh, acute catarrh of the upper respiratory tract, etc. However, found that only a small number of patients develop severe catarrh of the upper respiratory tract bacterial, allergic, chemical or mechanical etiology.

Etiology and pathogenesis. Of pathology that occurs in preterm children during the first months of life, pneumonia ranks first. Very often ill with pneumonia, children born with a weight of up to 1250 of them rare to find a child who during the neonatal period would not suffer a form of pneumonia. The high incidence of pneumonia caused by anatomical and physiological characteristics of the respiratory system in preterm infants and a number of aggravating moments at birth (birth asphyxia, hyaline membrane, intracranial injury).
Pneumonia pathogens include various respiratory viruses, bacteria Read more [...]
How is the infection of the host cell the virus in the details have not yet been elucidated. Relatively bacteriophages we have exact information, and it is conceivable that the introduction of other viruses in the cell is the same or similar manner. Initially virus attached to the cell and begins to penetrate, affecting their mutsinoliticheskim enzyme. Since then attacked the cell becomes resistant to infection, other viral particles, as would secure them (the phenomenon of interference). After that, in the infected cell while undetectable viral particles. The duration of the latent period, Read more [...]
Sometimes in recovery from infectious diseases are important specific antibodies. We know that after certain viral infections (such as measles) for life is absolute immunity to them, whereas after bacterial infection occurs only relative immunity, which often eventually disappears. The successful use of specific vaccines also demonstrate the role of antigen-antibody interactions in viral diseases. However, virus-infected body produces antibodies only in a relatively late stage of the disease, so they can influence the course of the disease only at a very late stage of her. Himself virus had Read more [...]
Enzyme therapy gives a clear beneficial effect of pneumonia in infants and viral pneumonia, the flu and acute respiratory diseases, mumps, rubella, measles, and other diseases. Usually, it can significantly reduce the duration of the disease, alleviate symptoms and prevent serious complications. Co-infections caused by bacteria, often require additional treatment with antibiotics.
Respiratory diseases viscous secretions and bronchial mucosa of the nasal cavity is diluted by the action of proteases, which facilitates their excretion. In addition, the anti-inflammatory effect of proteases to facilitate Read more [...]
All living cells of humans, animals and plants are divided initially in a certain rhythm. This continues for as long as they do not fill the space available to them, after which the division stops. This means that cell able to stop further growth, when its surface is in contact with other cells, such contact inhibits the mechanism of mitosis. This phenomenon is characteristic of every normal cell in the body, it is regulated by a feedback what-that enzyme system - the so-called contact inhibition factor, it can easily be observed in tissue culture. If there is a culture of neoplastic mutation Read more [...]
While bacterial infections that occur in humans and animals, we can very well be dealt with by chemotherapeutic agents in the treatment of viral diseases causal did just the first steps.
Although preventive measures (active and passive immunization, etc.) allowed in most civilized countries to suppress the spread of dangerous epidemic of viral infections, such as smallpox or polio, many viral diseases, no matter how trivial, we can now only be treated symptomatically.
The relatively young science of virology is being rapidly developed as a result of technological progress. In recent years, mainly Read more [...]
In terms of the molecular biology of cancer is not so raznolikoe disease. The same gene can be activated in any tissue. The nature of the tumor depends on the type of oncogene. It is determined only by the type of tissue. If virus gene affects white blood cells - developed leukemia oncogene activation in muscle cells or connective tissue sarcoma occurs, the transformation of epithelial cells leads to cancer.
Until recently had a lot of doubt as to whether viruses cause cancer in animals or only exist oncogenic human viruses. Gradually accumulated a lot of circumstantial evidence of the involvement Read more [...]
Interferon – Factor of nonspecific antiviral immunity, which is produced in a variety of cells in contact with the various cell inducers (live and inactivated viruses, endotoxins, etc.). Interferon plays an important role in the pathogenesis of viral infections by disrupting the formation of viruses. Interferon can be considered as an antiviral broad-spectrum antibiotic. Interferon used for the prevention and treatment of influenza and other acute respiratory diseases and eye diseases, and viral skin.
Medical science does not yet own reliable radical means, using which could prevent the development of influenza and other respiratory viral infections.
But we are not defenseless against these infections. Knowledge of their nature and mechanism of their distribution, biological defense mechanisms of the body is the basis for the rational construction of preventive measures.
To prevent influenza vaccines are prepared from live attenuated virus. Although this drug has such efficiency as smallpox, diphtheria, Polio and other vaccines, but with the right mass application significantly reduces the Read more [...]
Wealth of practical experience and the results of special studies are told that hardening does increase the body's resistance to infection, particularly respiratory viral diseases. The occurrence of these infections admitted to the general population associated with the common cold, that is, to excessive or prolonged cooling. Cold, of course, can not be the direct cause of these illnesses, they are caused by certain pathogens - viruses. However, the cold and contributes to a more severe course of respiratory infections. The best way is to protect yourself from the harmful effects of the Read more [...]
Parainfluenza infection in its current similar to the flu, but as a rule, takes place more easily, with less violation of the general condition of the patient. However, it can manifest severe croup, accompanied by pneumonia and other complications. Parainfluenza distinguish from influenza without special laboratory testing almost impossible. In practice, this condition is generally regarded as the flu. Parainfluenza infection spreads in the form of specific diseases or outbreaks, limited a territory or an institution.
Adenovirus infection - Disease, widespread in young children. It can cause Read more [...]
Diarrhea virus (synonym diarrhea virus) - Spicy, a little-studied viral disease characterized by a primary lesion of the gastrointestinal tract (diarrhea), fever, respiratory symptoms, and nervous system. Nosological independence viral diarrhea has not been proved, in the modern view, viral diarrhea - syndrome in some viral diseases, including enterovirus and adenovirus. Disease occurs in the form of sporadic cases and outbreaks of group, usually in children. The source of infection - a sick man. Infection occurs, apparently, nutritional means. Susceptibility, pathogenesis and immunity is not Read more [...]
Viruses (Synonym: inframikroby, ultravirusy, filterable viruses) - submicroscopic infectious agents are strict intracellular parasites. There are viruses, animals, plants and bacteria (see bacteriophage). The structure of the virus is a nucleic acid, which carries genetic information. Nucleic acid surrounded by a protein shell that protects it from external influences and provides for viral entry. The shell of some viruses also contains polysaccharides and lipids. Viruses belonging to the world of living beings manifested during virus infection cycle, which consists of the following stages: Read more [...]
Virological investigations - Studies intended for virus isolation and study of their properties, and to establish an etiological connection with certain virus diseases.
Material for the study is taken, depending on where the priority of virus multiplication in the body of the patient and how they highlight the external environment. The material is collected in a sterile container, quickly transported to the laboratory and stored prior to the study and frozen or on ice. Before using the material for virus isolation is treated with antibiotics (penicillin and streptomycin) to suppress extraneous Read more [...]
