Lung cancer emphysema

Many of our chronic diseases (asthma, lung cancer, emphysema, and bronchitis) could result from air pollution or be directly influenced by air pollution. Air samples can be very complex mixtures and GC is easily adapted to the separation and analyses of such mixtures. Two publications concerned with the adaptation of cryogenic gas chromatography to analyses of air samples illustrate this adaptation (34,35). 

Here again we have the problem of extrapolation but at least from a whole animal. In the whole animal, as in man, the multiple processes of metabolic activation and inactivation, and cellular interactions can occur and result in observable disease which is not the case in isolated cells. Therefore, why have we not been very successful in these types of studies Firstly, only a few life-time inhalation studies have been completed. Secondly, there has been only a limited success in developing animal models for human diseases, pulmonary and otherwise. We are interested in those diseases which are most likely to be associated with the inhalation of incompletely combusted plant and/or animal material. These diseases include lung cancer, emphysema, chronic bronchitis and cardiovascular disease. 

Chronic Pulmonary Toxicity Chronic damage to the lungs may be due to several subsequent exposures or due to one large dose that markedly exceeds the capacity of pulmonary defense, clearance, and repair mechanisms. Chronic pulmonary toxicity includes emphysema, chronic bronchitis, asthma, lung fibrosis, and lung cancer. The single most important reason for chronic pulmonary toxicity is tobacco smoke, which induces all types of chronic pulmonary toxicity, with the exception of fibrosis. 

Anodier problem can arise from the use of nonprescription cough medicine for self-treatment of a chronic cough. Indiscriminate use of antitussives by die general public may prevent early diagnosis and treatment of serious disorders, such as lung cancer and emphysema...

One of the major toxicity issues in cannabis consumption relates to the fact that it is most often smoked. Cannabis and tobacco smoke, apart from having different psychoactive constituents, are actually very similar in their composition (Hoffman et ai. 1975). Cannabis smoke is mutagenic, which gives it carcinogenic potential (Nahas and Latour 1992). Although no specific reports of lung cancer or emphysema from cannabis smoke exist, it is at least as harmful as tobacco smoke, containing three times as much tar and five times as much carbon monoxide (Wu et al. 1988). Cannabis smoke inflames the airways and reduces respiratory capacity. Airway obstruction and squamous metaplasias may also occur. 

Most patients who are addicted to cigarettes and other tobacco products at some time or another do seek treatment to help them stop. Perhaps they are faced with the crisis of medical illness (emphysema or lung cancer), or they have simply reached a point in life when they want to take better care of themselves. Whatever the motivation, smokers often seek professional help when trying to quit. We review the treatments for nicotine dependence. 

A subsequent mortality study of this same cohort found significant increases for death due to lung cancer. (Mortality from noncarcino-genic respiratory diseases including bronchitis, emphysema, and asthma also occurred in excess.)... 

A. There are no known health problems from oral Salvia use. However, it is known that smoking tobacco is damaging to your lungs and may cause cancer, emphysema, bronchitis, stroke and cardiovascular disease. These toxic side-effects of tobacco smoking are not due mainly to nicotine but rather to combustion products (tars and carbon monoxide), which are present whenever any type of plant material (e.g. Salvia) is smoked. Common sense will tell you that smoking Salvia, or any material, can be bad for your health. It is not known if Salvia can cause birth defects, but it is prudent to assume that it could. 

Marijuana smokers are at higher risk than nonusers for chronic lung diseases such as bronchitis, asthma, lung infections, and emphysema. Research also indicates that heavy marijuana use can lead to the DNA damage and cellular changes that produce lung cancer these changes appeared to occur in marijuana smokers at an... 

Smoking leads to respiratory problems other than lung cancer. It causes chronic bronchitis, emphysema, and lower resistance to flu and pneumonia. It worsens asthma symptoms in adults and children. As these problems persist, chronic obstructive pulmonary disease (COPD, airway obstruction) develops. Eighty to 85% of deaths due to COPD are from smoking. The role of nicotine in chronic lung diseases such as COPD, emphysema, and asthma is uncertain. However it is known that nicotine can cause an enzyme to be released which is able to destroy parts of the lungs as is seen in emphysema. 

Introduction and Statement of Problem. Current techniques to remove particulates in coal fired power plant flues are based on electrostatic precipitators, bag houses, cyclones and wet scrubbers. Typical collection efficiencies of such devices and the far less efficient cyclones are shown in Figure 1 (J,). Of interest is the fact that below 1 micrometer the efficiencies drop off rather precipitously. Work presented by Davies ( ), Figure 2, has shown that the human lower pulmonary system is unfortunately most efficient in absorbing and retaining particles in the 1 micrometer range. These particles are the primary cause of such respiratory ailments as bronchitis, emphysema and lung cancer. 

Pulmonary gene therapy is attractive for the treatmment of chronic bronchitis, cystic fibrosis, a-1 antitrypsin deficiency, familial emphysema, asthma, pulmonary infections, surfactant deficiency, pulmonary hypertension, lung cancer, and malignant mesothelioma. The pulmonary endothelium may act as a bioreactor for the production and secretion of therapeutic proteins, such as clotting factors and erythropoietin into the blood circulation. There is a potential benefit for acquired lung diseases, as well as cancers, to be controlled and possibly treated by expression of cytokines, surfactant, antioxidant enzymes, or mucoproteins within lung cells. 

You may never really think about breathing—until it becomes hard to do. In certain situations, normal human respiratory functions are disrupted. Hospitals use compressed oxygen for patients with respiratory disorders such as emphysema, pneumonia, or lung cancer. 

Smoking is the number one cause of lung cancer, heart disease, and emphysema. Smoking may help you relax.
