We aim to test the hypothesis that hypercalcemia produces pulmonary edema (PE) and to elucidate the mechanism. Experimentations were carried out in conscious rats and isolated perfused rat lungs. We evaluated PE by lung weight changes, protein concentration in bronchoalveolar lavage, dye leakage,
Ten N-(4-propoxyphenyl)-N'-(4-chlorophenethyl)-N"-substituted guanidines were synthesized from the corresponding 1-(4-propoxyphenyl)-3-substituted thiocarbamides and evaluated for anti-inflammatory and antiproteolytic properties. All substituted guanidines (50 mg/kg) provided 1-31% protection
Vascular adhesion protein-1 (VAP-1), an amine oxidase that is also known as a semicarbazide-sensitive amine oxidase (SSAO), is present in particularly high levels in human plasma, and is considered a potential therapeutic target for various inflammatory diseases, including diabetes complications
The influence of creatinine, urea and guanidine injection on the course of an artifically induced inflammatory reaction has been studied in rats. The formalin and bolus alba edema served as inflammatory models. It was shown that the inflammatory reaction was not significantly altered by urea. By
We evaluated the effect of pancreatic elastase (7 IU i.v.) on pulmonary interstitial pressure (Pip) in in situ rabbit lungs by a micropuncture technique through the intact parietal pleura. Pip was -10.8 +/- 2.2 (SD) cmH2O in the control condition, increased to +5.1 +/- 1.7 cmH2O at approximately 60
Novel thiazole derivatives were synthesized and evaluated as vascular adhesion protein-1 (VAP-1) inhibitors. Although we previously identified a compound (2) with potent VAP-1 inhibitory activity in rats, the human activity was relatively weak. Here, to improve the human VAP-1 inhibitory activity of
Plantaginis Semen is commonly used in traditional medicine to treat edema, hypertension, and diabetes. The commercially available Plantaginis Semen in China mainly comes from three species. To clarify the chemical composition and distinct different species of Plantaginis Semen, we established a
Acid aspiration or intrapulmonary instillation of gastric particles causes lung inflammation leading to acute lung injury (ALI). Hypercapnia exerts different effects on ALI caused by various insults. The effects of hypercapnia on lung inflammation and injury due to acid aspiration are yet to be
A series of 1,2,4-oxadiazoles and 1,2,4-thiadiazoles containing a 2,6-di-tert-butylphenol substituent were prepared and evaluated as dual inhibitors of 5-lipoxygenase and cyclooxygenase in rat basophilic leukemia (RBL-1) cells. Several of these compounds show oral efficacy in the rat carrageenan
Phorbol myristate acetate (PMA) causes acute lung injury (ALI). The present study was designed to elucidate the role of nitric oxide (NO), inducible NO synthase (iNOS), neutrophil elastase (NE) and other mediators in the ALI caused by PMA. In isolated rat's lungs, PMA at various doses (1, 2 and 4
BACKGROUND
The involvement of nitric oxide (NO) in acute lung injury (ALI) induced by fat embolism (FE) has not been investigated. The present study elucidated the role of NO in ALI because of FE.
METHODS
FE was produced by introduction of fatty acid (corn oil micelles) into the isolated rat's
Verbesina encelioides administered to sheep by gavage induced clinical signs of toxicity and pathologic lesions identical to those induced by Galega officinalis. Sheep had compromised respiratory function with shallow, rapid respiration and frothy exudate from the nares. Affected animals necropsied
BACKGROUND
In clinical trials, perioperative intravenous Na(+)/H(+) exchange isoform-1 (NHE1) inhibitors were only moderately effective in high-risk patients undergoing surgical reperfusion (GUARDIAN trial). However, effective myocardial concentrations of NHE1 inhibitor may not have been achieved by
Acute lung injury (ALI) caused by phorbol myristate acetate (PMA) is characterized by pulmonary edema and inflammatory cells infiltration. PMA-activated neutrophils in vivo and in vitro to release free radicals, pro-inflammatory cytokines, nitric oxide (NO) and other mediators. These mediators may
Guanabenz (2,6-dichlorobenzylidene amino guanidine acetate), an alpha 2-agonist, possesses antiinflammatory activity. Since leukotrienes (LT) and prostaglandins (PG) are proinflammatory substances, the effect of guanabenz on LT and PG synthesis by inflammatory cells was investigated. Guanabenz, but
