OBJECTIVE
To find out the effect of combining allopurinol with non-steroidal anti-inflammatory drugs on carrageenan-induced rat paw edema.
METHODS
The study was carried out at the College of Medicine, King Saud University, Riyadh, Kingdom of Saudi Arabia, over the period 1999 to 2000. Male wistar
Based on the hypothesis that Ca(2+) overload in the scala media may produce endolymphatic hydrops and generate free oxygen radicals (FOR), allopurinol, a xanthine oxidase inhibitor and free radical scavenger, was administered to guinea pigs after the surgical obliteration of the endolymphatic duct.
We examined the basis of reperfusion-induced pulmonary edema produced by pulmonary artery occlusion and subsequent reperfusion. After a 24-h period of occlusion of a rabbit pulmonary artery followed by a 2-h period of reperfusion, the lungs were removed from the animal and perfused with a 0.5 g%
Toxic oxidants (oxygen free radicals) have been implicated in the formation of brain edema from ischemia-reperfusion injury or tumor growth. We investigated the ability of an iron chelator, a calcium channel blocker, and a xanthine oxidase inhibitor to reduce formation of brain edema following a
The protective effect of a new potent protease inhibitor, ONO 3307, in combination with a xanthine oxidase inhibitor, allopurinol, was tested in pancreatico-biliary duct obstruction (PBDO) with temporary pancreatic ischemia in rats. After PBDO with ischemia, we observed hyperamylasemia, pancreatic
We measured lipid peroxidation of plasma, lung, and liver in anaesthetized sheep after third-degree burns involving 30% of total body surface. Animals were resuscitated to baseline filling pressures with lactated Ringer's solution and killed 10 hours after burn. Six sheep were pretreated with
We studied the role of reactive oxygen intermediates (ROI) in lipopolysaccharide (LPS)-induced pulmonary edema. LPS treatment (600 micrograms/mouse, IP) was associated with a marked induction of the superoxide-generating enzyme xanthine oxidase (XO) in serum and lung. Pretreatment with the
Free radicals have been shown to play an important role in ischemia-reperfusion injury in several organ systems; however, the role of free radicals in central nervous system ischemia has been less well studied. Many potential free radical-generating systems exist. The primary products of these
Sweet's syndrome, or acute febrile neutrophilic dermatosis, is an uncommon severe cutaneous condition, not previously associated with allopurinol therapy. We describe the case of an 87-year-old woman with hyperuricemia who developed classic Sweet's syndrome manifestations 8 days after being treated
BACKGROUND
Drug hypersensitivity syndrome is among the most severe drug hypersensitivity reactions and in rare cases it may progress to hemophagocytic lymphohistiocytosis. Herein, we report a case of allopurinol-induced drug reaction with eosinophilia and systemic symptoms complicated by
A fixed drug eruption (FDE) is characterized by the presence of a solitary or multiple, pruritic, well-circumscribed, erythematous plaques. These lesions have tendency to recur at same sites and heal with residual hyperpigmenation. With repeated attacks, the size and/or number of the lesions may
This study was designed to test whether use of allopurinol could improve lung preservation after 6 hours of cold storage. Thirty-two rabbits were divided into four groups (n = 8 each group): (1) the control group received no flush or storage, (2) the EC group received Euro-Collins (EC) solution for
We describe the presentation, diagnosis, management, and treatment of a 62-year-old woman with a medical history of gout who presented with a maculopapular rash, facial and tongue edema. Her initial presentation, coupled with a history of recent allopurinol use for systematic relief, led to the
One of the most important mechanisms in the production of ischemic damage after replantation surgery is the rise of oxygen free radicals during revascularization of ischemic tissues. Free radicals produce damage in the cell membranes (lipoperoxydation). This occurs not only in muscle tissue, but
OBJECTIVE
To study the effect of prophylactic agents allopurinol, verapamil, dexamethasone and trifluoperazine on ischemic intestinal damage.
METHODS
Sixty albino Wistar rats weighing 120-150 g were used. Group 1 animals underwent sham laparotomy without ischemia-reperfusion injury. Group 2 animals
