A local tendency to colds is caused by chronic hypertrophies and congestions of the nose and throat, by subacute or chronic catarrhs of these areas. Colds may be produced by any condition of the lungs or heart that may cause congestions of these mucous membranes, and particularly by such a condition of the nose or nasopharynx mucous membranes which will cause mouth breathing more or less constantly. Such patients are more sensitive to acute infections of the throat and lungs than are those who breathe through their nose.
A general tendency to colds is produced by hypersensitivity or decreased resistance of the body to microorganisms and dust particles in the atmosphere.

The skin is often called “the body’s first line of defence.” It acts as armour, resisting many germs that might harm the more delicate parts of the body. Any brain in the skin, even a pin prick, provides an opening for dangerous germs. Some germs enter the body through the nose and mouth and other natural openings. These areas provide warmth and moisture, in which germs thrive. When the membrane of the nose and throat becomes irritated, we cough or sneeze, blowing out the unwanted substances.
Other body liquids also provide a defence against disease. Tears, for example, wash bacteria from the eyes. Tears also contain substances that fight bacteria. Acid in the stomach kills many germs before they can reach other parts of the body.

Acute bronchitis is the disease of the bronchi. It is the inflammation of the bronchi. Its main symptom is a short painful dry cough associated with rapid respiration. The patient often complains of the pain in the throat, and behind the breastbone. He also feels discomfort in the chest and breathes heavily. Both dry and moist rảles are heard in the lungs.
The amount of the discharge from the bronchial mucous membrane is large. It accumulates in the bronchial tubes and makes the patient cough.

Louis Pasteur was born in 1822. He was a prominent French chemist, one of the founders of modern microbiology.
His research work helped much to establish the field of bacteriology. In his early years Pasteur devoted his energies to the discovery of microorganisms in wine and beer production. He introduced the idea of heat sterilization (pasteurization) for these products and milk too.
In later life he became interested in hydrophobia. Working in this field he developed the principle that viral pathogenic properties could be attenuated by passing the virus through the body of a proper animal. On the basis of these observations he developed a vaccine for hydrophobia.
Continuing his investigation L. Pasteur discovered the method to prevent some infectious diseases by introducing attenuated causative agents. This method is known as vaccination. It has helped to fight against many infectious diseases.

In 1871 the prominent Russian doctor V.A. Manassein published his report in which he described his numerous experiments with “penicillium glaucum”. During his observations of this particular plant V.A. Manassein discovered that many bacteria did not multiply and did not produce new ones in its presence. Due to this phenomenon V.A. Manassein began to investigate the properties of this plant. He determined that it grew well only in such an environment which was provided with oxygen, that is it was aerobic. The young culture of penicillium glaucum destroyed bacteria rapidly, they could not multiply and even disappeared in its presence. The great significance of penicillium glaucum as a protective agent against bacterial infection was clearly determined.

In 1872 the Russian scientist Professor of skin diseases A.G. Polotebnov published his article on penicillium glaucum.
He observed the same phenomenon which had been described by V.A. Manassein a year before. Professor A.G. Polotebnov used penicillium glaucum in his practice treating wounds and some skin diseases. The results of the treatment with penicillium glaucum were effective:
it controlled the development of infection and decreased the spread of microbes.
These Russian scientists were the first to observe the specific properties of penicillium glaucum though they were not able to use it in its pure form in medical treatment. The discovery of penicillin was made by the great English scientist Alexander Fleming in 1929.
