BACKGROUND
The etiology of canine chronic bronchitis (CB) is not completely understood, although exposure to environmental tobacco smoke (ETS) affects the airway inflammatory responses in some dogs with CB. The mechanism by which this occurs is unknown.
RESULTS
We investigated the concentrations and
We sought to evaluate possible changes in the prevalence of chronic bronchitis in relation to continuing or changing smoking status for marijuana and/or tobacco. For this purpose we followed 299 participants in a longitudinal cohort study of the impact of heavy habitual use of marijuana alone or
OBJECTIVE
The objective of this study was to determine the prevalence of chronic bronchitis (CB) and its association with sociodemographic factors and tobacco smoking in some rural communities in Ekiti state, Nigeria.
METHODS
This is a cross sectional study among adults aged e" 35 years in the three
The efficacy of health resort treatment was studied in 227 tobacco smokers suffering from chronic bronchitis. It was found that by the end of the treatment course patients that gave up smoking as compared with those continuing smoking revealed an increased tolerance to physical loads, an improvement
Background: Little is known of the repeatability and reliability of mucociliary clearance (MCC) in former tobacco smokers who have both chronic obstructive pulmonary disease (COPD) and chronic bronchitis (CB). Less is known of the effect of roflumilast, a selective inhibitor of PDE4, on MCC
OBJECTIVE
Nasal use of snuff is the predominant form of tobacco use among black South African women. This study examines the association between snuff use and chronic bronchitis (CB) among black South African women.
METHODS
The study investigated a nationally representative sample of 4464 black
Our aim was to describe how the prevalence of subjects exposed to environmental tobacco smoke (ETS) has changed from 1992 to 2012 in Finland. We also investigated the association between ETS and chronic bronchitis and cause-specific and all-cause OBJECTIVE
Risk factors beyond tobacco smoking associated with chronic bronchitis are not well understood. We sought to describe the prevalence and risk factors of chronic bronchitis across four distinct settings in Peru with overall low prevalence of tobacco smoking yet varying degrees of
This study aimed to determine the association between home and vehicle exposure to environmental tobacco smoke (ETS), and chronic bronchitis based on data from 64,961 non-smokers aged 12 years and older who participated in the 2005 Canadian Community Health Survey (CCHS). The proportion of

Prior evidence shows that environmental tobacco smoke is a risk factor for respiratory tract infections, wheeze, and asthma. Nicotine replacement therapy has been shown to increase smoking cessation. However, no prior studies have explored if parental use decreases the risk of
Tobacco smoke (TS) is a major causative agent to lead to chronic bronchitis (CB). However the mechanisms of CB induced by TS are unclear. In this report, rats were exposed to different concentrations of TS and the metabolic features of CB were characterized by using a nontargeted metabolic profiling
Cordyceps guangdongensis T. H. Li, Q. Y. Lin & B. Song (Cordycipitaceae) is a novel food approved by the Ministry of Public Health of China in 2013. Preliminary studies revealed that this novel food has multiple pharmacological activities such as anti-fatigue effect, antioxidant ability, prolonging
Nicotine is of interest as a major constituent of cigarette smoke and as an additive to chewing gum used to help patients to stop smoking. Specific pathogen-free rats were given an aerosol or injections of nicotine hydrogen (+)tartrate (L-isomer) for 2 or 3 weeks at three doses and the number of
Alveolar macrophages recovered by bronchoalveolar lavage from 14 heavy smokers with chronic bronchitis were assessed. Ultrastructural examination revealed marked cellular heterogeneity. Three subpopulations of alveolar macrophages were readily identifiable. These have been termed "young," "mature,"
