Some ciliostatic components ofcigarette smoke were studied as inhibitors of in vitro chemotaxis of human polymorphonuclear leukocytes (PMNs). In comparison to their concentration in an inhibitory level of cigarette smoke, the unsaturated aldehydes acrolein and crotonaldehyde were the most potent inhibitors, whereas nicotine, cyanide, acetaldehyde, and furfural were the next strongest inhibitors...

Maternal smoking has been recognized as a common cause of low birth weight, preterm birth and the decrease of gestational age period. Unfortunately, there is an increasing interest within public especially woman in Iran in the tobacco products consumption.

The inhalation toxicity of tobacco smoke has become one of the major public health problems of the 20th century. The chemical complexity of tobacco smoke confounds the task of identifying its toxic constituents. Tobacco smoke is comprised of thousands of chemical components arising primarily from volatilization and pyrolysis of the tobacco leaf (Stedman 1968; Green 1977). The chemical gamut run...

Lung cancer remains the most common fatal malignancy in the Western world. Survival rates have only improved modestly over the past three decades and new approaches are urgently required. It is clear that a concerted effort to reduce cigarette smoking is required. However, about 10% of patients with lung cancer are never smokers, indicating genetic or other predisposition. Lung cancer screening...

Chronic obstructive pulmonary disease (COPD) is the fourth leading cause of death in the United States, and cigarette smoking is the major risk factor for COPD. Fibroblasts play an important role in repair and lung homeostasis. Recent studies have demonstrated a reduced growth rate for lung fibroblasts in patients with COPD. In this study we examined the effect of cigarette smoke extract (CSE) ...

For years it has been postulated that the cigarette smoker adversely affects the nonsmoker by contaminating the indoor atmosphere (2,3). Recently, the U.S. Surgeon General, J. L. Steinfeld, focused public attention on the question when he requested a ban on smoking in closed public spaces (4). The average person spends the great majority of his time, probably 80 to 90 percent, indoors (5);thus,...

There is no doubt that the tar produced by condensing cigarette smoke is carcinogenic for mice (see Day, 1967). However, lung epithelium differs from the skin and the condensate differs from fresj cigarette smoke in, for example, the absence of the gaseous components. It appeared worth while to us, therefore, to attempt to produce lung carcinomas in mice by allowing them to breathe a mixture of...
