In India smoking is a common habit prevalent in both urban and rural areas. Cigarette smoking has extensive effects on respiratory function and is clearly implicated in the etiology of a number of respiratory diseases, particularly chronic bronchitis, emphysema, and bronchial carcinoma. An attempt has been made to study the pulmonary function tests among smoker and non-smoker population in a ru...

Pulmonary functions may be considerably influenced by changes in pulmonary haemodynamics in congenital heart disease. In analysing this problem we have found resting hyperventilation to be a common finding in these patients. There are few published studies on this relation and those that exist do not agree. In the present study the resting hyperventilation has been related to the pulmonary circ...

We examined the effect of physical training on cardiopulmonary function in 21 patients with chronic obstructive pulmonary disease and compared the results with similar observations in eight untrained patients. The training consisted of daily walking on a treadmill at increasing speeds and grades and other graded physical exercises. Evaluation of pulmonary function, including spirometric studies...

The bronchial vasculature is the systemic arterial blood supply to the lung. Although small relative to the pulmonary blood flow, the bronchial vasculature serves important functions and is modified in a variety of pulmonary and airway diseases. Congestion of the bronchial vasculature may narrow the airway lumen in inflammatory airway diseases, and formation of new bronchial vessels (angiogenes...

Background: β-thalassemia major is an inherited, transfusion-dependent chronic anemia which caused by decreased production of β-globin chains required for formation hemoglobin. Regular blood transfusion most important factors that help in improving the survival patients with TM; however, it leads to iron deposition many organs such as lung. Most studied concerned about effect on lung functions,...

Pulmonary function tests are valuable investigations in the management of patients with suspected or previously diagnosed respiratory disease. They aid diagnosis, help monitor response to treatment and can guide decisions regarding further treatment and intervention. The interpretation of pulmonary functions tests requires knowledge of respiratory physiology. In this review we describe investig...

OBJECTIVE To evaluate the relationship between pulmonary function tests, arterial blood gases, and thyroid gland functions in patients with chronic obstructive pulmonary disease (COPD). SUBJECTS AND METHODS Thirty-two patients (mean age 64.1 +/- 7.3 years, range 53-84 years) with stable COPD (mean duration of disease 11.1 +/- 9.1 years, range 1-30 years) and 15 healthy control cases participa...
