Sporn, A. Roberts and D. Goodman eds. Raven Press, New York, , However, many retinoids previously studied often lack selectivity and consequently exert harmful pleiotrophic effects and may cause patient death when used in therapeutically effective amounts.

Thus, the therapeutic use of retinoids in diseases other then cancer has been hmited by toxic side effects. COPD is a disease in which the lungs are obstructed due to the presence of at least one disease selected from asthma, emphysema and chronic bronchitis.

The term COPD was introduced because these conditions often co-exist and in individual cases it may be difficult to ascertain which disease is responsible for causing the lung obstruction Merck Manual. Clinically, COPD is diagnosed by reduced expiratory flow from the lungs that is constant over several months and in the case of chronic bronchitis persists for two or more consecutive years.

The most severe manifestations of COPD typically include symptoms characteristic of emphysema. Emphysema is a disease where the gas-exchange structures e. Anatomically, emphysema is defined by permanent airspace enlargement distal to terminal bronchioles e. Thus, the characteristic physiological abnormalities of emphysema are reduced gas exchange and expiratory gas flow.

Cigarette smoking is the most common cause of emphysema although other environmental toxins may also contribute to alveoh destruction. The injurious compounds present in these harmful agents can activate destructive processes that include, for example, the release of excessive amounts of proteases that overwhelm normal protective mechanisms, such as protease inhibitors present in the lung.

The imbalance between proteases and protease inhibitors present in the lung may lead to elastin matrix destruction, elastic recoil loss, tissue damage, and continuous lung function decline. The rate of lung damage may be decreased by reducing the amounts of toxins in the lung i.

However, the damaged alveolar structures are not repaired and lung function is not regained. At least four different types of emphysema have been described according to their locations in the secondary lobule: panlobar emphysema, centrilobular emphysema, distal lobular emphysema and paracicatrical emphysema.

The major symptom of emphysema is chronic shortness of breath. Other important symptoms of emphysema include but are not limited to chronic cough, coloration of the skin caused by lack of oxygen, shortness of breath with minimal physical activity and wheezing.

Additional symptoms that may be associated with emphysema include but are not limited to vision abnormalities, dizziness, temporary cessation of respiration, anxiety, swelling, fatigue, insomnia and memory loss. Emphysema is typically diagnosed by a physical examination that shows decreased and abnormal breathing sounds, wheezing and prolonged exhalation.

Pulmonary function tests, reduced oxygen levels in the blood and a chest X-ray may be used to confirm a diagnosis of emphysema. No effective methods for reversing the clinical indications of emphysema currently exist in the art.

Oxygen treatment is frequently used in situations where lung function has been so severely impaired that sufficient oxygen cannot be absorbed from the air. Lung reduction surgery may be used to treat patients with severe emphysema. Here, damaged portions of the lung are removed, which allows the normal portions of the lung to expand more fully and benefit from increased aeration. Finally, lung transplantation is another surgical alternative available to individuals with emphysema, which may increase quality of life but does not significantly improve life expectancy.

Alveoli are formed during development by division of sacchules that constitute the gas- exchange elements of the immature lung.

The melting point at each reaction differed 1st trial, of starting material to product in this lab 6. Write a detailed, arrow-pushing, step-by-step synthesis for the conversion lab and the organic acid to cause polarity difference. The heat breaks the intermolecular forces between the hydrogen Explain why the product is soluble in hexanes but. Compare the melting point of the product with the starting material. The compound was 0.
