A 43-year-old Chinese man with a silicosis history was admitted to our hospital due to bilateral lower extremity edema for 1 year, exacerbating with hematuria for 2 months. He started working as a coal miner 30 years ago, and was diagnosed as silicosis 3 months ago. Lab tests revealed hematuria 3+,
Nicorandil, an antianginal and potassium channel opener agent, has different useful impacts on cardiovascular and respiratory systems. Its effect against silicosis has not been discussed yet, therefore, this is an attempt to decide whether nicorandil can reduce silica-induced lung injury in rats.
Small ring-shaped images, related to 2nd or 3rd bronchial walls are seen in prahilar lung region in 80% of chest Xray films, when a bronchus in seen "end on". This bronchial wall thickening (greater than 0.3 mm) is present in numerous lung diseases such as silicosis, bronchiectasis and pulmonary
To provide a precise correlation between high-resolution computed tomographic (CT) findings and histologic studies of various parenchymal lung diseases, 20 fixed and inflated lungs were studied as follows: (a) Every lung was cut at the corresponding CT level into 1.5-mm-thick sections, (b) selected
Stephania Tetrandrae Radix is one of the common traditional Chinese medicines, which has bitter and pungent taste as well as cold properties. It can subside edema, get rid of rheumatism and relieve pain. Therefore, it is mainly used for the treatment of rheumatism arthralgia, edema, dysuria,
The pneumoconioses, extrinsic allergic alveolitis, lung damage due to irritant gases, fumes, and smoke constitute the occupational lung diseases that affect the lung parenchyma. The pneumoconioses are diseases resulting from the accumulation of dust in the lungs. The ILO has established a
Current topics for occupational and environmental medicine and physiology in the U.S.A., especially in the National Institute for Occupational Safety and Health (NIOSH), and the University of California, San Francisco, are reviewed. Reduction of the rate for occupational lung diseases is one of the
BACKGROUND
Mining operations conducted at high altitudes provide health challenges for workers as well as for medical personnel.
OBJECTIVE
To review the literature regarding adverse health effects and toxic exposures that may be associated with mining operations conducted at altitude and to discuss
The lung has a limited number of patterns of reaction to inhaled particles. The disease observed depends upon the location: conducting airways, terminal bronchioles and alveoli, and upon the nature of inflammation induced: acute, subacute or chronic. Many different agents cause narrowing of
The mechanism by which monosodium urate (MSU) crystals induce inflammation is not completely understood. Few studies have shown that MSU is capable of stimulating the release of IL-1β in the absence of LPS treatment. The purinergic P2X7 receptor is involved in the release of IL-1β in
