Computed tomography (CT) of the lungs makes it possible to study individual airways. A technique using high-resolution-CT (HRCT) has been developed to measure the internal size of the bronchi. Five normal subjects had a conventional HRCT scan at full, deep inspiration. The internal size of the airways from segmental to the sixth generation bronchi was measured using an original method of data a...

132S 35th Annual Aspen Lung Conference specific T cell clones from allergic patients,8 and by T cells in the bronchi of asthmatic subjects that are able to secrete cytokines, including 1L5, with important effects on eosinophils and other cell types. There is also strong cijcumstanlial evidence to support the role of the eosinciphil as the main effector cell involved in the bronchial inflammatio...

OBJECTIVE To present a case of endobronchial metastasis from a seminoma mimicking a primary pulmonary mass on X-ray radiograph. CLINICAL PRESENTATION AND INTERVENTION A 27-year-old man presented with a 1-month history of hemoptysis. Thorax computerized tomography of the patient obtained at the level of the main right bronchi demonstrated a mass with a size of 7 x 6 cm and a peripheral lobulat...

If you get the printed book in on-line book store, you may also find the same problem. So, you must move store to store and search for the available there. But, it will not happen here. The book that we will offer right here is the soft file concept. This is what make you can easily find and get this surgery of the trachea and bronchi by reading this site. We offer you the best product, always ...

The hypothesis that increased reactivity in asthma is not always limited to the bronchi but also exists in the mediator releasing system was investigated in forty-five asthmatic children, approximately half of whom had exercise-induced bronchoconstriction (EIB). The bronchial threshold to histamine was measured as an indicator of the reactivity of the bronchi and the histamine release from leuc...

We propose a new local feature called three dimensional(3D) concentration index for analyzing line texture patterns in the 3D space. This feature can be used for evaluating quantitatively local concentration of lines at each point of a 3D line pattern. In the paper, simulations using arti cial patterns is performed to examine basic properties of the index. The index is also applied to patterns ...

Background: Self-expanding Y metal stent insertion is a safe and effective palliative method for malignant lesions involving the lower trachea, tracheal carina, main-stem bronchi. However, length degree of airway stenosis in different patients tend to vary, which leads call customized that could achieve better treatment effect.

were designed to attain two objects: first, to determine the nature of the nervous mechanism which governs the bronchi, a knowledge of which is obviously essential to a proper conception of the pathology of such disorders as affect these structures ; and, second, to attain to some precise knowledge of the influences which may be exerted by various drugs upon that mechanism. These objects have b...
