To evaluate the cellular and biochemical composition of bronchoalveolar fluid in high-altitude pulmonary edema (HAPE), we performed bronchoalveolar lavage in three climbers with HAPE in a research facility at 4400 m on Mount McKinley. Three healthy climbers were used as controls. The HAPE fluids
We studied the effects of regional alveolar hypoxia on permeability pulmonary edema resulting from venous air embolization. Anesthetized dogs had the left upper lobe removed and a double-lumen tube placed so that right lung and left lower lobe (LLL) could be ventilated independently. Air was infused
Incisional wounds of the abdominal skin, aponeurosis, stomach and colon were investigated microscopically for a comparison of the findings between uremic and normal rats. The grade of edema and number of inflammatory cells were increased in the rats with uremia and the granulation zone was also
A 12-year-old boy with recurrent skin ulceration, chronic generalized lymphedema, and mild mental retardation was found to excrete massive amounts of dipeptides, most (but not all) of which had proline or hydroxyproline as the carboxyl terminal residue. Glycylproline predominated. Prolidase
The clinical use of bleomycin in the treatment of squamous cell carcinomas, lymphomas and testicular tumours has been limited by its toxic effects, the most serious being pulmonary injury. The present study was undertaken to investigate whether alpha-tocopherol, incorporated in liposomes and
The aim of this study was to evaluate the effects of melatonin on the inflammatory response and hydroxyproline production in an experimental acute and chronic model of trinitrobenzene sulfonic (TNBS) acid-induced colitis in Wistar rats. In the acute model, melatonin (0.5, 1, and 2 mg/kg, i.p.) was
An experimental model of chronic pancreatitis was induced by a retrograde injection of a viscous solution consisting of zein-oleic acid-linoleic acid (0.05 ml/100 g body weight) into the rat pancreatic duct. Histologic and biochemical changes were investigated over a period of 6 months after
The pathophysiology of the acute lung injury (ALI) is characterized by the damage of alveolar epithelial cells, which can be repaired by exogenous bone marrow-derived mesenchymal stem cells (BMSCs). However, the migration and differentiation abilities of BMSCs are not sufficient for the purpose, and
This study aimed to examine whether lung tissue extracellular matrix (ECM) hydrogels have protective effects on radiation-induced lung injury (RILI). The cytocompatibility and histocompatibility were tested for the obtained ECM-derived hydrogel. Sprague-Dawley rats were randomly divided into three
BACKGROUND
Pulmonary fibrosis occurs in approximately 60% of patients with acute respiratory distress syndrome and has been significantly correlated with a poor outcome. The overexpression of angiotensin (Ang) II can induce lung inflammation and fibrosis. This observation, coupled with the knowledge
Thousands of death in Africa and other developing nations are still attributed to trypanosomiasis. Excessive sleep has been associated with increased inflammation. We report herein, the synthesis, antitrypanosomal and anti-inflammatory activities of eight new carboxamide derivatives bearing
The effect of shikonin (SK) on granulation tissue formation was biochemically evaluated and the biological effect of SK on cotton pellet induced granulation tissue formation and the induction of hind paw edema was compared with that of lambda-carrageenan (carrageenan) in rats. The dry weight of
A standard rabbit vaginal irritation test was used to evaluate the morphologic reaction to an aqueous solution of a nonionic spermicidal detergent, nonoxynol-9 (N-9). Various amounts of N-9, between 2.5 mg and 50 mg, were incorporated into cylindrical collagen sponges which were retained in the
Significant fibrosis and acinar atrophy are characteristics of chronic pancreatitis; however, because of the lack of a reproducible model, early phases of these changes are poorly understood. We have developed a model of severe hyperstimulation and obstruction pancreatitis (SHOP) to better define
A range finding study for experimental induction of pulmonary fibrosis in which female Syrian golden hamsters received five subcutaneous injections of 0.8, 0.6, 0.4, 0.2 or 0 mg of N-methyl-N-nitrosourethane (MNUR) once a week or once per two weeks revealed most of the animals of the 0.8 mg group to
