Download file to see previous pages It is quite unfortunate that over the past three decades the research has not shown much progress, it has focused only on the pathogenic roles of cigarette smoke, inflammation, protease and antiprotease balance. Research has also established an association of COPD with cigarette smoking; and patients with emphysema are known to suffer from a gene deficiency in an inhibitor of a neutrophils protease (Stang et al, 2000). The theory of cigarette-inflammation-protease has done a lot in the field of COPD epidemiology and pathology but is not able to reduce the pervasiveness and morbidity caused by COPD. It is therefore imperative to impose an urgent necessity for research in this area. The research is directed to sustain novel concepts and innovative experimental approaches and techniques pertinently suitable to COPD research. The research is also directed to explicate the cellular pathways involved in COPD pathogenesis. This is a step helpful in clinical trials of potential therapeutics. Explanation of these pathways is the step to develop a capability of pharmaceutical industry to design the mechanism specific drugs.

The anonymity of COPD pathogenesis:
COPD encompasses emphysema and chronic obstructive bronchitis, both these conditions relentlessly limits airflow that is not significantly reversed by bronchodilators. COPD progressively turn down the pulmonary functions with a rapid pace as compared to that in normal aging. Stimulating factors known to induce changes in animal lungs are cigarette smoke, pancreatic elastase, bacterial lipopolysaccharides, cadmium, chloramine-T, oxidants, silica, and rigorous malnourishment (Shapiro, 2000). It is established that many apparently dissimilar pathways are capable of causing emphysema or bronchitis, ...Download file to see next pages Read More

...-mass index and customised MRC dyspnea scale. Conclusion In summary, COPD is a disease that results in limited airflow into and out of airways because of loss of elasticity in the air sacs and the airways, destruction of the walls between air sacs, thickening and inflammation of the walls of airways and unusual making of more mucus which could clog the airways. COPD gradually worsens and could lead to death. Even though reversing the damage on the lungs could be almost impossible, appropriate measures could be taken to prevent further damage, majorly reducing cigarette smoking.

Literature Review Chronic Obstructive Pulmonary Disease (COPD) is a common disease “characterized by persistence of air flow limitation that is progressive and associated with an enhanced chronic inflammatory response in the airways and lungs to noxious particles or gases” (Pauwels, Buist, Calverley, Jenkins, & Hurd, 2001). COPD is the fourth killer disease globally, and it is projected that the disease will be the third cause of mortality by the year 2020 (Adams et al., 2007; US Department of Health and Human Services, 2003). It is categorized under chronic illnesses with most of the patients being aged people. COPD limits the daily activities of aged patients over time. Research indicates that exercise...

Although there has been continuous public education about the relationship of COPD and smoking, about 20% of the American adult population has COPD (Dodd, 2010). A recent survey revealed that exacerbation to the disorder due to acute bronchitis and other conditions accounts for about 14 million of the clinical visits annually. COPD is said to be one of the most disabling condition in the middle aged and the elderly. In the USA, exacerbation of COPD accounts for 10% of the hospital admission and about 30,000 of deaths per year (Nicholas, 2006). Situation Cognition refers the high order neural...

The Diagnosis and Treatment of Disease Outline: The Roles of the Imaging and Treatment Modalities

Dramatic developments in the field of science and technology have provided newer and enhanced diagnostic tools to make arrive at a more precise diagnosis on one side and on the other side given new meaning to the traditional treatment modalities, as well as creating new treatment modalities. 

Peering inside the human body for a better understanding of any abnormalities within that are the cause for illness in a patient had remained an unrealized need until the advent of the x-ray imaging technique. Since then advances in the x-ray imaging techniques have led to new imaging modalities to remove the inadequacies that were experienced through the use of mere x-rays. Fluoroscopy is one such development in imaging modal...

The impact of Plant Disease on New Zealand

Transmission of PMTV occurs through inoculation of sap in 26 species belonging to Solanaceae or Chenopodiaceae and to Tetragonia expansa and also through grafting (A. Reavy., W. Kashiwazaki., & Barker,1995 ). In some cases, PMTV is known to be transmitted by mechanical inoculation also.

Since PMTV is vectored only through S.subterranea the infection of plants with PMTV depends on the life cycle of S.subterranea which takes about 10-14 days. The life cycle of S.subterranean takes place in 2 phases: Phase I) This is the primary stage of the life cycle initiated with the germination of resting spores known as sporangiosori or cystosori persisting in the soil as spore balls with thick cell walls into zoosporangia. These...

Most of the human diseases were classified under two broad categories; 1) genetic diseases and 2) environmental diseases. In genetic diseases, mutation or loss of function in any of the vital genes leads to disease condition and they are generally cured by artificial supplementation of a vital component. For example, in sickle cell anemia where a patient having mutation in both copies of the hemoglobin gene leads to sickle-shaped RBC. The only permanent cure for this disease is bone marrow transplant and gen...

Antibiotic Resistance of Bacterial Agents of Disease

The prevalence of increased antibiotic resistance of bacterial agents of disease is a serious clinical concern because it limits and reduces the efficiency of the treatment options that are available. The mechanism of the development of antibiotic resistance has been attributed to bacteria’s capacity to mutate. The mutation alters existing resistance determinants to antimicrobial agents and produces different drug targets that have decreased antibiotic affinity. Thus, mutators that have high mutation frequencies could have important roles in developing antibiotic resistance (Chopra, O’Neill, & Miller, 2003). It is believed that bacteria mutate as part of its endogenous survival mechanism. In E. coli, defects in gen...

... the cause. COPD (Chronic Obstructive Pulmonary Disease) Chronic Obstructive Pulmonary Disease (COPD) makes it hard for you to breathe. Coughing up mucus is often the first sign of COPD. Chronic bronchitis and emphysema are common COPDs (NLM, 2009). Your airways branch out inside your lungs like an upside-down tree. At the end of each branch are small, balloon-like air sacs. In healthy people, both the airways and air sacs are springy and elastic. When you breathe in, each air sac fills with air like a small balloon. The balloon deflates when you exhale. In COPD, your airways and air sacs lose their shape and become floppy, like a stretched-out rubber band. Cigarette smoking is the most common cause of COPD. Breathing in other kinds...
