Cardiovascular Diseases

At present scientists consider that much attention must be paid to the treatment of cardiovascular diseases. They are, first of all, arterial hypertension, then atherosclerosis, particularly of the coronary arteries, whose gravest complication is infarction of the myocardium and lastly, cardiac insufficiency caused by various diseases of the heart.

Mass scale epidemiological check-ups of population show that people contract coronary insufficiency and hypertension from 40 to 60 years of age. At the same time, nowadays one frequently meets coronary insufficiency and infarction of the myocardium in young people of 20-30 years of age. Hypertension, especially symptomatic hypertension, which is a symptom of diseases of some organs or systems, for example, of the kidneys or endocrine glands, may set in at an even earlier age than that.

Considerable headway has been registered lately in the diagnostics of symptomatic hypertension. Methods of diagnostics have been improved to the extent when it is possible to discover symptomatic hypertensions which 10-15 years ago could be found only in 5-6 per cent of patients - in 23 per cent of the patients suffering from arterial hypertension. This is of great importance for the successful combating of arterial hypertension, because the knowledge of the cause of hypertension makes it easier to prescribe its successful treatment.

Definite success has also been achieved in the treatment of atherosclerosis, coronary insufficiency and infarction of the myocardium which are closely related to it.

Exercise 3. Make up a summary of the given text using the following expressions.

1) To be of great importance; at present; scientists consider; cardiovascular diseases;

2) to give gravest complications; arterial hypertension and atherosclerosis of the coronary arteries;

3) check-ups of population; mass scale; epidemiological; to show that; not only old people; to have coronary insufficiency and infarction of the myocardium; but young people of 20-30 years of age;

4) in the treatment of some cardiovascular diseases; to have been achieved; definite success.

UNIT THIRTEEN

 

I Speaking Lymphatic System and Lymphoid Tissue
II Grammar Objective Participle Construction
III Independent Work Disorders of Lymphatic System and Lymphoid Tissue

After careful study of this unit you should be able to:

- list three major functions of the lymphatic system;

- explain the difference between the blood and lymphatic capillaries;

- name the two main lymphatic ducts and describe the area drained by each;

- list the major structures of the lymphatic system and give the locations and functions of

-:ach.


Exercise 3. Read the text, remember the information about the lymphatic system from your anatomy lessons.

The lymphatic system consists of capillaries, nodes, ducts and lymphatic vessels, spread through the whole body (Fig. 13-1).

About 2 liters of lymph fill the lymphatic vessels. The lymphatic capillaries drain away excess tissue fluid that does not return to the blood capillaries. Then, they are to absorb protein from the tissue fluid and return it to the bloodstream. Before the lymph reaches the veins, it flows through a series of filters, called lymph nodes, where bacteria and other foreign substances are destroyed.

Lymphatic capillaries made of endothelium allow for easy passage of soluble materials and water. The lymphatic capillary begins blindly and the other end of it communicates with the larger lymphatic vessel.

The lymphatic vessels are thin-walled and delicate, they have the valves to prevent backflow in the same way. The lymphatic vessels include superficial and deep sets. They accompany the similar veins. The lymphatic vessels are named according to their location (see Fig. 13-1).

The two terminal vessels are the right lymphatic duct and the thoracic duct.

The right lymphatic duct receives the lymph from the right side of the head, neck, thorax and the right arm and empties into the right subclavian vein.

The rest of the body is drained by the thoracic duct, which is larger than the right lymphatic duct, and it empties into the left subclavian vein.

Lymph is moved by compression of the lymphatic vessels as skeletal muscles contract during movement. The lymph nodes are made of lymphoid tissue, which is characterized by removal of impurities (carbon particles, cancer cells, pathogenic organisms, dead blood cells) through filtration and phagocytosis and production of antibodies (substances in the blood that aid in combating infection) or attacking of foreign invaders directly. The lymph nodes are small, rounded masses covered with fibrous connective capsule, they have the hilus (the exit) for lymph vessels carrying the lymph out of the node.

The nodes are the filters of lymph. Another lymphoid masses are tonsils. They are designed to filter tissue fluid. The thymus is located in the upper thorax beneath the sternum. It has been considered to be a part of the lymphatic system. The thymus plays a key role in the development of the immune system before birth and during the first few months of infancy.

The thymus is most active during early life. After puberty (період статевої зрілості), the tissue undergoes changes, it shrinks in size and is replaced by connective tissue.

The spleen is an organ designed to filter the blood. It's located in the abdominal cavity under the diaphragm, it is soft with a purplish color. It's a flattened organ about 12.5 to 16 cm long and 5 to 7.5 cm wide. The spleen has an unusually large blood supply. The function of the spleen are listed below:

1. Cleansing the blood by filtration and phagocytosis.

2. Destroying old worn-out red blood cells.

3. Producing red blood cells before birth.

4. Serving as a storage of blood.

Disorders of Lymphatic System and Lymphoid Tissue

 

There are many different disorders of the lymphatic system.

In inflammation of the lymphatic vessels called lymphangitis, red streaks can be seen extending along an extremity. Septicemia or blood poisoning may occur because of streptococci.

Elephantiasis is a great enlargement of the lower extremities resulting from blockage of lymphatic vessels with tiny parasities earned by insects (flies or mosoquitos). The disease is common in Asia and in some of the Pacific islands. No cure is known.

Lymphadenitis is the inflammation of the lymph nodes, they become larger and tender. This condition reflects the body's attempt to combat an infection.

Cervical lymphadenitis is a symptom of measles, searlet fever, septic sore throat, diphtheria.

Lymphadenopathy is the disease of lymph nodes. Splenomegaly is enlargement of the spleen, accompanies acute infections, such as scarlet fever, typhoid fever, syphilis.

Hodgkin's disease is the malignant disease with enlargement of lymph nodes, commonly occurs in young men. The nodes in the neck, armpit, thorax and groin enlarge. Chemotherapy and radiotherapy have been used with good results.

Any tumor benign or malignant occuring in the lymphoid tissue is called a lymphoma. Lymphosarcoma is a malignant tumor. It is a very rare disease. Early surgery is the only possible cure.

Body Defenses Against Disease

In our environment there is a great number of organisms harmful to the human being. The job of protecting us from these harmful agents belongs in part to certain blood cells and the lymphatic system, which together make up our immune system.

The human body has the ability to produce toxins, which damage the body. Inflammation is the body's effort to get rid of anything that irritates it.

Irritants can be bacteria, friction, chemicals, X-rays, fire, cuts or blows, etc.

Cells infected with viruses and certain other agents produce interferon, the substance that prevents infection of other cells.

Immunity is the power of an individual to resist or overcome the effects of a particular disease or other harmful agents.

There are two kinds of immunity: inborn and acquired. Acquired immunity can be natural or artificial; and also it can be active or passive.

Each person has his own inborn immunity. Acquired immunity is obtained during the life of the person. The immunity response is based on a reaction between antigens and antibodies. Antigens are any foreign substances entering the body.

Lymphocytes react to these foreign substances, they can destroy foreign cells directly, or release substances that stimulate other lymphocytes and macrophages in the destruction of foreign cells (clones of plasma cells). These plasma cells produce specific antibodies that circulate in the blood as gamma globulin fraction.

Each time a person is invaded by the organisms of a disease, his cells may produce antibodies that provide immunity against the infection. Such immunity may last for years and in some cases it lasts for a whole life. It is active immunity. Passive immunity is acquired by a fetus through the placenta and by infants for about six months. Nursing an infant can lengthen this period of protection owing to the presence of specific antibodies in breast milk.

Artificially acquired immunity is created by vaccination or immunization in active or passive ways. Active immunization is immunization with vaccines. Passive immunization is administration of immune serum (antiserum).

Here we can name some disorders of the immune system:

- allergy is hypersensivity to normally harmless substances (allergen);

- autoimmunity is abnormal response to body's own tissues;

- immune deficiency disease is failure in the immune system. It can be hereditary or acquired (AIDS);

- cancer may be partly due to failure of immune system, because it destroys body cells.

Exercise 3. What are the Latin/Greek equivalents of the following English words?

Cells, tissue, allergy, disease, substance, milk, bacterium, antibody, toxin, lymphocyte, macrophage.

Exercise 4. Answer the questions. What do we call:

1) a person who takes care of patients?

2) a doctor who operates on patients?

3) a doctor who treats patients with different medicines and remedies?

4) a person who discovers something new in the field of science?

5) a house where students live?

6) a grown-up person?

7) the organ which pumps the blood through the arteries and veins?

8) a fixed period of time during which students study?

9) the system of the body, which defends the organism from harmful agents?

Exercise 5. Give some examples of inborn immunity, acquired immunity. What is the basic difference between inborn and acquired immunity?

Exercise 6. Answer the following questions.

1) What is the subject of immunology?

2) What is active immunization?

3) What is passive immunization?

4) What takes part in immunity?

5) What is the difference between antigens and antibodies?

6) What does the term "inflammation" mean?

7) What disorders of the immune system do you know?

Exercise 7. Read the information and answer the questions.

- What is the role of vaccines?

- What vaccines are used to prevent infectious diseases?

Immunity can be provided artificially by vaccination and other forms of immunization. A vaccine is a preparation containing the offending organisms - usually in a weakened form that will not cause the actual disease. Currently there are vaccines for polio, measles, rubella, mumps, chicken pox, shingles, and some strains of influenza.

Exercise 8. Translate into English.

1. Алергія - це підвищена чутливість до алергенів.

III. Independent Work: AIDS

Exercise 1. Read the text. Make a vocabulary of new words.

 

AIDS

AIDS means acquired immune deficiency syndrome. It is caused by the human immunodeficiency virus (HIV). The only identified routes of transmission are through the blood and semen contaminated with the HIV. Transmission can be through sexual contact, exposure to contamined blood and blood products (transfusions, sharing needles used for illegal IV drugs, accidental needle puncture, broken area on the skin directly exposed to contaminated blood), and from pregnant female to unborn child.

When the HIV enters the bloodstream, it attacks the immune system and weakens the person's ability to fight disease. Target cells are T-cells (type of white blood cells called lymphocytes that are produced in the thymus). Although they do not secrete antibodies, T-cells are essential for normal immune function. Without them, cell-mediated immunity deteriorates, allowing opportunistic diseases to invade the body. In response to this invasion, the body begins to produce antibodies. Within two weeks to three months after infection, these antibodies can usually be detected by a blood test.

There are three possible outcomes for individuals who become infected by HIV:

- they can remain healthy, asymptomatic carriers of the virus;

- they can develop AIDS-related complex (ARC);

- they can develop classic AIDS.

Currently, no cure exists for AIDS. All asymptomatic HIV positive persons require periodic T4 cell tests (also called CD4 cell count) usually every six months to monitor the status of their immune system. When the CD4 cell count falls below 500/mm3 (normal is 1000/ mm3), pharmacotherapy is often initiated, followed by laboratory monitoring of the T4 cells count every three months (AIDS Guide, 1992). Because of the increased risk of opportunistic infections, additional screening tests include:

- skin tests: purified protein derivative (PPD) to rule out tuberculosis (TB);

- Candida, mumps, or tetanus toxoid to evaluate patient's immune response;

- serum studies for hepatitis В antibodies.

 

Exercise 2. Make a summary to retell the text.

Exercise 3. Answer the following questions.

1) What does AIDS mean?

2) What causes AIDS?

3) What are the ways of transmission?

4) Why is such disease so dangerous?

5) Name three possible outcomes for persons infected with HIV.

6) Can doctors treat AIDS?
