IN THE CHILDREN'S WARD

Professor Stukov is making his daily rounds in the clinic. Two assistants and several students are following him listening to his remarks and paying attention to every word he says.

Now they all are standing round the bed of one of the little patients. You can read they name of the boy “Klimov Boris” and the denomination of disease on his bed – card. The little boy is namely suffering from anemia. He is very pale and weak, all his movements are slow. He is recovering now but very slowly. This case is a simple one. The boy simple needs vitamins. In many cases food rich in vitamins improves the general state of patients. Fruits generally are rich in vitamins. The usual died during illness consists of milk, butter, eggs, wheat bread and fruit – apples, oranges, prunes, grapes.
We usually give the children suffering from anemia orange juice. It is easy to prepare orange juice. You can easily do it yourself. Peel an orange and crunch it with a spoon in a cup, then pour off the juice into another cup.

MICROORGANISMS

All the microorganisms that exist can be divided into two main groups- aerobic and anaerobic. Aerobic microorganisms must have atmospheric free oxygen for their life and growth. However it is known that free oxygen is not favorable for the development of anaerobic microorganisms.

Bacteria vary in shape and according to this feature they are divided into some groups. Spherical bacteria have been called cocci. They are also subdivided into several groups. Rod-shaped bacteria are called bacilli.
When bacteria multiply they divide. The growing organism increases in size up to a certain limit and in due time divides. The process of division depend on the conditions of the environment.
Any minute virulent microorganisms may invade the human body. But due to the local protective agents of the human organism they are destroyed. In this case no disease occurs.
However the local protective agents of the human organism are not always able to destroy the invading microorganisms completely. It is known that in such a case a local or general infection may occur.
Most of the microorganisms produce diseases when they enter the tissue and destroy it. If one examines under the microscope the alveoli of the lung of the man with lobar pneumonia a great number of pneumococcal can be seen.
While the disease develops the lung may be considerably impaired because of the consolidations which may develop in it.
But the human organism can fight against the microorganisms which have passed its first protective barriers, i.e. skin and mucous membranes.
