The role of alveolar macrophages in the production of granulocyte/ macrophage colony-stimulating factor(s) by the rat lung was investigated. Lavaged lungs, when incubated at proper weight per volume of culture medium, produced the same amount of colony-stimulating factor as unlavaged ones. Both lavaged and unlavaged lungs produced similar types of colony-stimulating factor (s). Prolonged i...

Pulmonary nodular lymphoid hyperplasia (PNLH) is a reactive lymphoid proliferation manifesting as multiple solitary nodules or localized infiltrates in the lungs. It is a type of benign lymphoproliferative disease that can affect the lungs. We present the case of a 41-year-old female patient with respiratory symptoms such as productive cough, left chest pain, and dyspnea. Imaging findings revea...

background: linguatula serrata is one of well known members of pentastomida which infects both human and animals. the aim of this study was to evaluate the prevalence of l. serrata in mesenteric lymph nodes, livers and lungs of camels slaughtered in tabriz area, iran. methods: mesenteric lymph nodes (mlns), livers and lungs of 140 one-humped camels slaughtered in tabriz , north-west of iran wer...

In order to obtain insight into disturbances of pulmonary function in newborn infants we have to consider the physiological changes that occur in the lungs at birth. By combining the information obtained from a variety of animal experiments with our clinical observations, we can construct a fairly coherent picture of some of these events and see the ways in which their normal course is disturbe...

In the latter half of the 20th century, Los Angeles had, by many measures, higher levels of photochemical air pollutants than any other major city in the United States (Fig. 1). To address this problem, the California Air Resources Board and its partners became leaders in quantifying the health effects of air pollutants and in aggressively implementing pollution-control strategies. Even with th...

Within their small air sacs, our lungs exchange oxygen (O 2 ) from the for carbon dioxide (CO produced by bodies. In these spaces, O moves into blood vessels while CO out air. Lung diseases can impair airflow and reduce number of in lungs, making it harder to take eliminate . These changes contribute symptoms like breathlessness. The relationship between flow is called V/Q, where V ventilation—...
