e two lungs are not quite mirror images of each other. e right lung, which is the slightly larger of the two, is divided into three lobes, and the le lung is divided into two lobes.
e lungs extend from the collar-bone to the diaphragm in the thoracic cavity. e diaphragm is a muscular partition which separates the thoracic from the abdominal cavity and aids in the process of breathing. e diaphragm contracts and descends with each inspiration, enlarges the area in the thoracic cavity and when the lungs are full, the diaphragm relaxes and elevates, making the area in the thoracic cavity smaller, and thus increasing the air pressure in the thorax. Air then is expelled out of the lungs to equalize the pressure; this is called expiration.

DRUGS AFFECTING THE RESPIRATORY SYSTEM
Drugs can be delivered to the lungs by inhalation, oral, or parenteral routes. Inhalation is preferred because the drug is delivered directly to the target tissue-the airways and is eective in doses that do not cause signicant systemic side eects. Clinically useful drugs act by various mechanisms, for example, by relaxing bronchial smooth muscle, or modulating the inammatory response.
Drugs used to treat asthma. Asthma is a chronic disease that aects approximately 10 million of the USA population. e disease is characterized by episodes of acute bronchoconstriction causing shortness of breath, cough, chest tightness, wheezing and rapid respirations. ese acute symptoms may resolve spontaneously or more oen, require therapy such as β
-agonist. A second delayed or
2
late-phase response may occur 4 to 12 hours later, and may require treatment with steroids. Asthma, unlike chronic bronchitis, cystic brosisor bronchiectasis, is usually not progressive disease-it does not inevitably leadto crippling chronic obstructive lung disease. Deaths due to asthma are infrequent, but morbidity results in signicant hospitalization. e goal of therapyis to relieve symptoms and to prevent recurrence of asthmatic attacks, if possible.
Adrenergic agonists.
1. Short acting drugs: Most clinically useful β-agonists have a rapid(15 to 30 minutes) onset of action and provide relief for 5 to 6 hours. Toxic side eects, such as tachycardia, hyperglycemia are minimized when the drugs are delivered by inhalation rather than by systemic routes.
2. Long acting drugs: salmeterol xonatoate is chemical analog of albuterol, but diers by having a long lipophilic side chain that increases the anity of the drug for the β-adrenoceptor. Salmeterol has a long duration of action, providing bronchodilation for at least 12 hours. Salmeterol has a slow onset of action and should not be used in acute asthmatic attacks.
113
Corticosteroids.
Inhaled glucocorticoids are the drugs of the rst choice in patients with moderate to severe asthma who require inhalation of β
-adrenergic agonists more than once daily. Severe asthma
2
may also require systemic glucocorticoids, usually for short term. Inhaled glucocorticoids oen reduce (or eliminate) the need for oral glucocorticoids in patients with severe asthma. To be eective in controlling inammation, glucocorticoids must be taken continuously.

8. Read and translate the text. ECZEMA VULGARE
Eczema vulgare is a synonym for contact eczema, which is due to direct contact with a noxious substance and develops in the area of skin that has been exposed to the substance in question.
e morphological changes typical of eczema vulgare comprise reddening, swelling, vesiculation, weeping, the formation of crusts and scales, and – in chronic forms of the disease – inltration,
117
lichenication, skin ssures, and hyperkeratosic callosities, particularly on the hands and feet.
ough usually presenting a fairly uniform clinical picture, eczema vulgare is not a single nosological entity, but can be subdivided on the basis of aetiopathogenetic criteria into three main categories:
- Eczema due to sensitivity
- Toxic-degenerative contact eczema
- Allergic contact eczema.
Eczema due to sensitivity occurs in subjects displaying an exceptionally high degree of cutaneous sensitivity, in whom even minor forms of skin irritation suce to provoke an eczematous reaction. e primary cause is a constitutional weakness, aecting the lipid lm and acid mantle of the skin, which prevents the skin from performing its protective function adequately.
Toxic-degenerative contact eczema develops in cases where the skin has been subjected to prolonged contact with noxious substances, such as alkalis, acids, solvents, etc., or where repeated soaking or mechanical strains imposed on the skin have overtaxed its powers of resistance. Here, once again, the individual sensitivity of the skin plays an important role. Even the most resistant of skins will become diseased if exposed to a high enough concentration of the oending contact under these circumstances, however, the disease is then referred to not as contact eczema, but as toxic dermatitis.
Allergic contact eczema occurs as the result of sensitization of the skin to exogenous allergens, such as chromium, nickel, formaldehyde, dye-stus, turpentine, etc.; it is attributable to an antigen-antibody reaction of delayed onset, i.e. of the type also provoked by tuberculin. Responsible for the production of the antibodies participating in this antigen-antibody reaction are lymphocytes which, having become sensitized by the invading allergen, subsequently multiply in the lymph nodes. Since this process of lymphocyte sensitization and multiplication takes some time to occur, the resultant antigen-antibody reaction is delayed –
118
in contrast to the immediate type of reaction seen in cases of shock and urticaria, in which preformed circulating antibodies from mast cells proceed at once the release of such direct-acting vasotropic substances as histamine.
