Generic Zyloprim is used for treating gout caused by excessive levels of uric acid in the blood (hyperuricemia). Hyperuricemia occurs when the body produces more uric acid than it can eliminate. The uric acid forms crystals in joints (gouty arthritis) and tissues, causing inflammation and pain. Elevated blood uric acid levels also can cause kidney disease and stones. Generic Zyloprim prevents the production of uric acid by blocking the activity of the enzyme that converts purines to uric acid.

There was a significant increase of the small bowel ischaemic lesions over the time for both experimental groups. The lesions frequency and severity were significantly more increased in the EC group than in the UW group, for jejunal segments at 8 hours, in jejunal and ileal segments at 24 and in jejunal and ileal segments at 48 hours.

There are peroxidative changes during the reperfusion of the rat small intestine following a 1h period of total ischaemia. That is demonstrated by the increases of the concentrations of glutathione disulphide and of thiobarbituric acid-reactive substances. An important source of the active oxygen species leading to peroxidations is the degradation of purine nucleotides. The nucleotides and their derivatives were measured by an ion-pair reversed-phase high-performance liquid chromatographic separation in a single analysis within 40 min. Modification of the elution gradient resulted in a high resolution of nucleosides and nucleobases, including allopurinol and oxypurinol. The decrease of the nucleoside triphosphate concentration and the increase of nucleoside monophosphate concentration, followed by accumulations of nucleosides and nucleobases in the course of the ischaemia were measured. During reperfusion the nucleotide pools are filled up. Restoration of adenosine triphosphate and guanosine triphosphate can be accelerated by application of the xanthine oxidoreductase inhibitor allopurinol. Pretreatment of the animals with allopurinol also diminished the formation of glutathione disulphide and thiobarbituric acid-reactive substances.

Examination of claims from a large hospital database showed that treatment with rasburicase, compared with allopurinol, was associated with a significant reduction in critical care days but not with a significant difference in mean LOS or total cost.

The roles of nitric oxide (NO) and serotonin (5-HT) in the development of gastric mucosal lesions induced by compound 48/80 (48/80) were investigated in rats. Repeated i.p. administration of 48/80 (1 mg/kg) produced damage in the stomach with severe oedema in the submucosa. The lesions induced by 48/80 were prevented by FPL-52694 (a mast cell stabilizer) and methysergide but not tripelennamine. The lesions were also inhibited by simultaneous administration of N(G)-monomethyl-L-arginine (L-NMMA), and this effect was mimicked by inducible NO synthase (iNOS) inhibitors, such as aminoguanidine or dexamethasone and significantly antagonized by coadministration of L-arginine. The mucosal myeloperoxidase activity, thiobarbituric acid reactants and vascular permeability in the stomach were all increased after 48/80 treatment and the changes were also attenuated by cotreatment with L-NMMA. Repeated s.c. treatment with 5-HT (20 mg/kg) provoked similar gastric lesions, which were also prevented by methysergide and iNOS inhibitors, as well as antioxidative drugs, such as allopurinol (a xanthine oxidase inhibitor) and hydroxyurea (a neutrophil-reducing agent). The Ca2 -independent NO synthase (NOS) activity was increased in the gastric mucosa after administration of 48/80 or 5-HT and this change was inhibited by dexamethasone. These results suggest that: (i) the repeated administration of 48/80 induced inflammatory gastric lesions in the rat stomach, mediated by endogenous 5-HT; (ii) NO/iNOS is involved in the pathogenic mechanism of 48/80-induced gastric lesions, in addition to oxyradical formation; and (iii) the deleterious role of NO in this lesion model can be accounted for by a cytotoxic action of peroxynitrite that is formed in the presence of superoxide radicals.

Allergic skin disorders in the elderly may arise from contact with or ingestion of offending allergens. Itching associated with skin allergy must be distinguished from other causes of itching in the elderly such as xerosis, itching due to systemic disease and bullous disease. Although elderly people have somewhat decreased cell-mediated immunity and may be harder to sensitise under experimental conditions, they have had many years to acquire allergic responses, and therefore develop contact dermatitis frequently. Patch testing is a valuable tool to diagnose contact allergy and should be used often in the elderly, particularly in patients at high risk of contact dermatitis, such as those with chronic lower extremity dermatitis or ulcers due to venous stasis. When prescribing topical medications to high risk patients, a knowledge of the common sensitisers is important. In addition to allergy to medicaments and dressings used to treat stasis ulcers, contact allergy to dental prostheses and medications used to treat ocular disease are common in the elderly as a result of increased usage and exposure. Rash caused by ingested allergens is much more commonly due to medications than to food in the elderly. Allergic noneczematous dermatoses in the elderly are commonly drug-induced. Urticarial skin reactions are often associated with the administration of antibacterials, nonsteroidal anti-inflammatory drugs (NSAIDs), antidepressants or opioids. Morbilliform rashes are a common sign of systemic reaction to anticonvulsants, gold, allopurinol or diuretics. Phototoxic reactions may be associated with the administration of tetracyclines, diuretics, NSAIDs and antihyperglycaemic agents. Patient-specific variables such as HLA type and concomitant medication may affect the likelihood of an allergic response to medication. Many elderly patients take multiple medications, which can make diagnosis of drug allergy difficult because diagnosis is most commonly accomplished by observing clinical response once the medication is withdrawn. In the case of lichenoid cutaneous reactions, clinical improvement may take several months after withdrawal of the offending drug. Laboratory tests to detect drug-induced allergic skin disorders may be available in the future.

Xanthine oxidoreductase (XOR) is a molybdenum-containing enzyme that under physiological conditions catalyzes the final two steps in purine catabolism, ultimately generating uric acid for excretion. Here we have investigated four naturally occurring compounds that have been reported to be inhibitors of XOR in order to examine the nature of their inhibition utilizing in vitro steady-state kinetic studies. We find that luteolin and quercetin are competitive inhibitors and that silibinin is a mixed-type inhibitor of the enzyme in vitro, and, unlike allopurinol, the inhibition is not time-dependent. These three natural products also decrease the production of superoxide by the enzyme. In contrast, and contrary to previous reports in the literature based on in vivo and other nonmechanistic studies, we find that curcumin did not inhibit the activity of purified XO nor its superoxide production in vitro.

Several ferulic acid ethyl esters (3a-h) were synthesized under the Knoevengel reaction condition and they were further reduced to afford the respective allylic alcohol derivatives (4a-g). Some of them were evaluated for the xanthine oxidase (XO) inhibitory activity. Among them, 3h exhibited a significant inhibitory activity with an IC50 value of 1.35 x 10(-5) M, while the IC50 value of allopurinol used as the positive control was 1.49 x 10(-5) M. The study suggested that the higher acidity of the phenolic OH group in the ferulic acid derivatives might result in improved XO inhibitory activity.

This study suggests an association between allopurinol and the biosynthesis of thyroid hormones. Allopurinol prevents the hyperthyroid state, which is mediated predominantly by triiodothyronine and not by XO. This issue has to be questioned in further studies where allopurinol is administered in control subjects.

Classical xanthinuria type II is an autosomal recessive disorder characterized by deficiency of xanthine dehydrogenase and aldehyde oxidase activities due to lack of a common sulfido-olybdenum cofactor (MoCo). Two mutations, both in the N-terminal domain of the Human Molybdenum Cofactor Sulfurase (HMCS), were reported in patients with type II xanthinuria. Whereas the N-terminal domain of HMCS was demonstrated to have cysteine desulfurase activity, the C-terminal domain hypothetically transfers the sulfur to the MoCo. We describe the first mutation in the C-terminal domain of HMCS identified in a Bedouin-Arab child presenting with urolithiasis and in an asymptomatic Jewish female. Patients were diagnosed with type II xanthinuria by homozygosity mapping and/or allopurinol loading test. The Bedouin-Arab child was homozygous for a c.2326C>T (p.Arg776Cys) mutation, while the female patient was compound heterozygous for this and a novel c.1034insA (p.Gln347fsStop379) mutation in the N-terminal domain of HMCS. Cosegregation of the homozygous mutant genotype with hypouricemia and hypouricosuria was demonstrated in the Bedouin family. Haplotype analysis indicated that p.Arg776Cys is a recurrent mutation. Arg776 together with six surrounding amino acid residues were found fully conserved and predicted to be buried in homologous eukaryotic MoCo sulfurases. Moreover, Arg776 is conserved in a diversity of eukaryotic and prokaryotic proteins that posses a domain homologous to the C-terminal domain of HMCS. Our findings suggest that Arg776 is essential for a core structure of the C-terminal domain of the HMCS and identification of a mutation at this site may contribute clarifying the mechanism of MoCo sulfuration.

To test this hypothesis, we exploited our rabbit pup model of glycerol-induced germinal matrix hemorrhage-intraventricular hemorrhage. We delivered rabbit pups prematurely (E29) by cesarean section and administered intraperitoneal glycerol at 2 hours postnatal age. Free-radical adducts, including nitrotyrosine, 4-hyroxynonenal, and 8-hydroxy-deoxyguanosine as well as O(2)(.-) and H(2)O(2) levels were measured in the forebrain. To determine the source of free-radical generation, we used inhibitors for NAD(P)H oxidase (apocynin), xanthine oxidase (allopurinol), cyclo-oxygenase-2 (indomethacin), or nitric oxide synthases (L-NAME). Intraventricular hemorrhage pups were treated with apocynin and cell death was compared between apocynin-treated and vehicle-treated pups.

We have investigated the disposition and plasma uric acid lowering effect of oxipurinol in ten healthy individuals following oral administration of three different formulations of oxipurinol and of allopurinol in equimolar doses. The reduction of plasma uric acid was clearcut up to 48 h. As estimated from plasma AUC0-infinity, Cmax, tmax, tlag, and urinary drug excretion, a conventional rapid release preparation of oxipurinol sodium was clearly superior to oxipurinol as free acid and to enteric coated microtablets of oxipurinol sodium. Plasma oxipurinol concentrations following a single dose of the conventional formulation of oxipurinol sodium were approximately 25% lower than those observed after an equimolar dose (300 mg) of allopurinol, but mean Cmax reached the value reported to be necessary for 90% inhibition of xanthine oxidase. Since prolonged administration will result in accumulation of oxipurinol because of its slow elimination, this type of oxipurinol formulation can be expected to meet the therapeutic requirements for a drug to lower plasma uric acid.

A 34-year-old woman was diagnosed with Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS), most likelyrelated to a reaction to allopurinol.The patient presented with a 2-week history of a painful pruritic rash that started on her back and progressed to the rest of her body over a five-day period. The eruption started after several new drugs were started, including allopurinol for hyperuricemia. On physical examination, the patient had a diffuse morbilliform eruption and geometric intact bullae limited to the boundaries of tattoos.Most presentations of DRESS include a morbilliform eruption.  However, DRESS does not commonly present with bullae. There have been no known reported cases of bullae forming in the area of tattoos in cases of DRESS. This unique presentation suggests that a component of the tattoo or tattooing process alters the cutaneous immune response, creating an immunocompromiseddistrict. This alteration may promote a greater localized reaction in the setting of widespread skin involvement in DRESS.

Cardiac surgery patients with hyperuricemia (n=141) were randomized to a febuxostat group or an allopurinol group. The study was single-blind, so the treatment was not known by the investigators. The primary endpoint was serum uric acid (UA) level. Secondary endpoints included serum creatinine, urinary albumin, cystatin-C, oxidized low-density lipoprotein (LDL), eicosapentaenoic acid/arachidonic acid ratio, total cholesterol, triglycerides, LDL, high-density lipoprotein, high-sensitivity C-reactive protein, blood pressure, heart rate, pulse wave velocity (PWV), ejection fraction, left ventricular mass index (LVMI), and adverse reactions. UA level was significantly lower in the febuxostat group than the allopurinol group from 1 month of treatment onward. Serum creatinine, urinary albumin, cystatin-C and oxidized LDL were also significantly lower in the febuxostat group. There were no significant changes in systolic blood pressure, PWV, and LVMI in the allopurinol group, but these parameters all had a significant decrease in the febuxostat group.

Although liver transplantation from non-heart-beating donors (NHBDs) is an effective way to overcome shortage of donors, primary graft nonfunction is often noted in these grafts. We have previously reported that edaravone, a free radical scavenger, has a cytoprotective effect on warm ischemia-reperfusion injury and improves the function of liver grafts from NHBDs in a rat model of ischemia-reperfusion. The purpose of this study was to investigate the effects of edaravone on liver transplantations from NHBDs.

Because transplantation success is influenced by the quality of the graft, the objective of this study was to find parameters to evaluate transplant livers in the recipient centre. In 64 liver grafts, the venous effluates of a portal back-table flush were investigated for various parameters. Amongst them, glutathione S-transferase (GST), glutamate dehydrogenase (GLDH) and the leucocyte count were found superior in predicting graft survival. Using the combination of these parameters, 100-day graft survival of between 95% (all parameters positive) and 0% (all parameters negative) was predicted. We concluded that good liver grafts are characterized by a low width of injury (cytosolic component: GST), a low depth of injury (mitochondrial component: GLDH), as well as by a potential to induce tolerance (passenger leucocytes). Perfusate analysis seems to be a valuable tool to recognize problematic grafts in advance and to quantify the "graft factor" in considerations concerning quality control.

We previously examined factors that affect the measured derivatives of reactive oxygen metabolites (d-ROMs), an indicator of reactive oxygen species production, and biological antioxidant potential (BAP), an indicator of antioxidant capacity, in typical health checkup examinees and reported the usefulness of measuring both indicators simultaneously. In addition, a positive correlation reportedly exists between d-ROMs and the visceral fat area measured by using computed tomography. A recent study of the relationship between uric acid levels and various obesity-related factors found that visceral fat was the factor most strongly related to uric acid levels. Uric acid is itself a potent endogenous antioxidant, but because reactive oxygen species are produced during uric acid generation, it is suggested that uric acid may have opposing effects. The objective of this study was to analyze the effect of febuxostat, a novel xanthine oxidase inhibitor, on oxidative stress.

1. Uric acid estimations by the uricase-UV and the autoanalyzer colorimetric procedures were compared. 2. At all levels of serum uric acid concentration measured, results with the uricase-UV method were significantly lower than those with the phosphotungstate method. 3. The buy zyloprim online data indicate that the critical uric acid level (measured by the autoanalyzer) at which allopurinol, uricosuric, and other agents are instituted should be decreased approximately 10 per cent when determinations are done by the uricase method.

The effects of allopurinol (HPP) at concentrations ranging from 0.33-1.83 mM and of aspirin (ASA) from 0.28-2.22 mM, were studied on the rat whole-embryo culture system. Embryos were explanted at day 10 of gestation and cultured for 48 h, either in the absence or in the presence of rat and human S9. HPP proved to be potentially embryolethal and teratogenic without any S9, while it was embryolethal with rat S9 and dysmorphogenic with human S9. ASA showed an embryolethal and teratogenic potency without any S9 samples. These responses were increased in the presence of rat S9, while ASA embryolethality was predominant with human S9. These results obtained on rat embryos in culture suggest a correlation between the species origin of the biotransforming system buy zyloprim online and the known teratogenicity of HPP in sensitive animal models. However, ASA elicited responses not in agreement with the known teratogenic response in rodents.

Inconclusive findings about infection risks, importantly the use of immunosuppressive medications in patients who have undergone large-joint total joint arthroplasty, challenge efforts to provide evidence-based perioperative total joint arthroplasty recommendations to improve surgical outcomes. Thus, the aim of this buy zyloprim online study was to describe risk factors for developing a post-operative infection in patients undergoing TJA of a large joint (total hip arthroplasty, total knee arthroplasty, or total shoulder arthroplasty) by identifying clinical and demographic factors, including the use of high-risk medications (i.e., prednisone and immunosuppressive medications) and diagnoses [i.e., rheumatoid arthritis (RA), osteoarthritis (OA), gout, obesity, and diabetes mellitus] that are linked to infection status, controlling for length of follow-up.

Peroxidative loading during the reoxygenation of the rat small intestine following a complete ischemia was demonstrated in in vivo-experiments by the increases of the glutathione disulphide (GSSG): total buy zyloprim online glutathione ratio and the concentration of thiobarbituric acid-reactive substances (TBA-RS). The pretreatment of the rats with allopurinol diminished the accumulation of GSSG and of TBA-RS. From these effects was concluded that the purine nucleotide degradation is an important source of oxygen reduction products leading to peroxidations. The concentrations of nucleotides, nucleosides and nucleobases were measured by an ion-pair reversed-phase HPLC. The restoration of ATP and GTP concentrations during the reoxygenation period was accelerated by the application of allopurinol.

Plasma urea nitrogen in hyperoxically reperfused rabbits was significantly elevated above the normoxic group (P = .01), the sham group (P = .02), and the allopurinol group (P = .04) by 72 hours. These coincided with a significantly elevated histopathologic injury score in hyperoxically reperfused rabbits compared with sham (P = .019), normoxic (P = .035), and allopurinol-pretreated hyperoxically reperfused animals (P = .037).

New knowledge of the pathophysiology and evolution of hypoxic-ischemic brain injuries has made feasible interventions to improve clinical outcomes for newborns surviving birth asphyxia. Brain injury following hypoxic-ischemic insult is a complex process evolving over hours to days, which provides a unique window of opportunity for neuroprotective treatment interventions. The specific pathologic processes preceding the onset of irreversible cerebral injury appear to be a combination of several mechanisms that are variable according to the severity and duration of the insult and to biochemical modifications in the brain. Advances in neuroimaging, brain monitoring techniques, and tissue biomarkers have improved the ability to diagnose, monitor, and care for newborn infants with neonatal encephalopathy, as well as to predict their outcome. The role of oxidative stress in newborn morbidity with respect to the higher risk of free radical damage in these babies is growing. However, challenges remain in early identification of infants at risk for neonatal encephalopathy, determination of timing and extent of hypoxic buy zyloprim online -ischemic brain injury, as well as optimal management and treatment duration. Potential neuroprotective strategies targeting different pathways leading to neuronal cell death in response to hypoxic-ischemic insult have been investigated: hypothermia, erythropoietin, iminobiotin, deferioxamine, magnesium, allopurinol, xenon, melatonin and statins. Hypothermia is currently the only recognized beneficial therapy. However, many infants still develop significant adverse outcomes. It is becoming evident that the association of moderate hypothermia with neuroprotective drugs may enhance the outcome. By virtue of their pleiotropic effects without toxic effects, melatonin and statins may act at different levels of the multiple mechanisms responsible for the progression of the neurodegenerative process and represent promising neuroprotectants, alone or as additional adjunctive therapy, for reducing brain injury and its long-term sequelae in infants. More clinical studies are needed to clarify the role of these potential neuroprotective drugs.

Allopurinol-induced hypersensitivity syndrome is characterized by an idiosyncratic reaction involving multiple-organs, which usually begins 2 to 6 weeks after starting allopurinol. In rare cases, the adverse reactions to allopurinol are accompanied by a variety of liver injury, such as reactive hepatitis, granulomatous hepatitis, vanishing bile duct syndrome, or fulminant hepatic failure. Here we report a case with granulomatous hepatitis and ductopenia. A 69-year-old man with chronic renal failure, hyperuricemia, and previously normal liver function presented with jaundice, skin rash, and fever 2 weeks after taking allopurinol (200 mg/day). In histopathology, a liver biopsy specimen showed mild spotty necrosis of hepatocytes, marked cholestasis in parenchyma, and some granulomas in the portal area. There were vacuolar degeneration in the interlobular bile ducts and ductopenia in the portal tracts. Pathologic criteria strongly suggested the presence of allopurinol-induced granulomatous hepatitis with ductopenia and cholestasis. The Ventolin Salbutamol Syrup patient fully recovered following the early administration of systemic corticosteroid therapy.

To determine whether NAT2 genotyping could be used interchangeably with caffeine phenotyping in assessing N-acetyltransferase activity in epidemiological studies, sources of interindividual variability in N-acetyltransferase activity were assessed among 90 subjects of various ethnic backgrounds in Hawaii. Forty-three subjects were patients with Geodon 60 Mg in situ colorectal cancer treated by polypectomy, and 47 were healthy population controls. Subjects were administered a lifestyle questionnaire and were evaluated for N-acetyltransferase activity by caffeine phenotyping. NAT2 genotype was also assessed by PCR amplification of peripheral leukocyte DNA for the M1, M2, and M3 variant alleles. Fifty-four % of the overall variation in acetylation activity was explained by the three genotype categories (homozygous variant, heterozygous, and homozygous wild-type). This proportion was reduced to 42% when genotype was modeled using only two categories ("slow" being homozygous variant; "rapid" being all others). Use of gout medications (probenecid or allopurinol), consumption of heavily browned fish, and P450IA2 activity (also measured by caffeine phenotyping), together explained another 11% of the variance. No association was found between acetylation activity and sex; race; age; education; smoking; physical activity; weight; consumption of coffee, alcohol, red meat, processed meat, and cruciferous vegetables; or use of menopausal estrogens, after taking genotype into account. Results were similar for colorectal cancer patients and controls. Considerable variation in acetylation activity was observed within the homozygous wild-type group. This study suggests that the use of genotyping, instead of phenotyping, to assess the association of acetylation with cancer risk is unlikely to introduce major misclassification or bias, especially when the three genotype categories are modeled and the sample size is large. However, when the rapid acetylation phenotype is the at-risk group (e.g., when studying colon career), phenotyping appears judicious given the variability in acetylation activity within this group.

Although healthcare providers have arrived at a relatively comfortable zone of accepted clinical practice in the management of cutaneous sarcoidosis, virtually every treatment is based on minimal evidence-based data and relies almost exclusively on anecdotal information. Although it would be convenient to blame this state of affairs on the lack of certainty about disease aetiology, the unavoidable fact is that little has been executed, even in the realm of well designed comparative trials. Nonetheless, worldwide accepted standard therapies for sarcoidosis include the administration of Ventolin Liquid Dosage corticosteroids, antimalarials and methotrexate. A stepwise approach to patient care is appropriate, and potent topical corticosteroids (e.g. clobetasol) or repeated intralesional injections of triamcinolone (3-10 mg/mL) may be all that is needed in mild skin-limited disease. In patients requiring systemic therapy for recalcitrant or deforming skin lesions (or for widespread disease), corticosteroids (e.g. prednisone 40-80 mg/day, tapered accordingly) used alone or in combination with antimalarials or methotrexate may be indicated. Antimalarials and methotrexate are considered second-line interventions and may be used as monotherapy for steroid-resistant sarcoidosis or in patients unable to tolerate steroids. Given the concern regarding ocular toxicity, the maximum dosages of chloroquine and hydroxychloroquine should not exceed 3.5 and 6.5 mg/kg/day, respectively. Methotrexate is given in weekly doses of 10-30 mg, with the caveat that haematological, gastrointestinal, pulmonary and hepatic toxicities are possible. Despite universal acceptance as standard care, the aforementioned treatments often result in an incomplete clinical response or unacceptable adverse events. In such situations, more innovative treatment options may be used. Treatments that may well gain widespread future use include the tumour necrosis factor-alpha inhibitors infliximab and adalimumab. Experience is limited, but early reports are promising. Infliximab is administered via intravenous infusion at doses of 3-10 mg/kg at 0, 2 and 6 weeks and as indicated thereafter, whereas adalimumab is injected subcutaneously at doses of 40 mg either weekly or every 2 weeks. Because adalimumab is not approved for the management of sarcoidosis, the optimum dose administration interval is uncertain. However, it has been given in both weekly and every other week regimens. Isotretinoin, 0.5-2 mg/kg/day, has been used successfully in a handful of reported cases. However, the teratogenic potential of isotretinoin is often prohibitive considering that the primary demographic group likely to develop sarcoidosis is women of childbearing potential. Thalidomide at dosages of 50 to >400 mg/day has limited, albeit promising, supporting data. However, access is restricted in many countries because of a deserved pregnancy category X rating. Melatonin (20 mg/day) and allopurinol (100-300 mg/day) are not well studied in cutaneous sarcoidosis, and the clinical experience with tetracycline derivatives has been mixed. That said, there are compelling reports of therapeutic benefit with both doxycycline and minocycline. Because neither of these agents is associated with the severe toxicity of cytotoxic drugs, they may serve as effective therapy in some patients. Pentoxifylline (400 mg three times daily) has been of use in a small number of reported cases of pulmonary sarcoidosis, but there are no reports on its use in patients with primarily cutaneous disease. Both ciclosporin and chlorambucil have been largely abandoned given their associated toxicity and disappointingly unreliable efficacy. Finally, laser therapy is a newer modality that may provide patients with a quick and non-invasive treatment option for cutaneous sarcoidosis.

Inhibitors of cytochrome P450, such as SK&F 525-A, prolong the duration of xylazine-ketamine anesthesia and cause pulmonary edema (PE) and death in rats. To determine the cause of PE, Sprague-Dawley rats were given a single dose of xylazine (21 mg/kg, im) alone or in combination with ketamine (45 mg/kg, Epivir 25 Mg im) and/or SK&F 525-A (50 mg/kg, ip) and percentage lung to body weight (%LW/BW) ratios (as an indicator of PE) were compared. The results indicated that xylazine caused PE which was independent of ketamine and was enhanced by SK&F 525-A. Subsequently, it was determined that 42 mg/kg xylazine, im, is an optimal edemagenic dose. Xylazine (42 mg/kg, im) increased the %LW/BW ratio as compared to control. Pleural effusion (PLE) of various amounts was observed in 75% of the animals. The pleural fluid to serum protein ratio for xylazine was similar to that obtained for alpha-naphthylthiourea (5 mg/kg, ip). Extensive serous PLE and alveolar edema with hemorrhage were found at necropsy in xylazine-treated rats. Pretreatment with yohimbine (4.2 mg/kg), prazosin (20 mg/kg), tolazoline (20 mg/kg), yohimbine (4.2 mg/kg) plus prazosin (20 mg/kg), atropine (20 mg/kg), dimethyl sulfoxide (DMSO) (7.8 g/kg), allopurinol (50 mg/kg), superoxide dismutase (20,000 U/kg), catalase (20,000 U/kg), BW755C (50 mg/kg), ibuprofen (50 mg/kg), cystathionine (100 mg/kg) plus taurine (100 mg/kg) did not affect the %LW/BW ratio. PLE was increased by yohimbine, yohimbine plus prazosin, and allopurinol, reduced by DMSO, and not changed in other groups. The results indicate that xylazine caused increased-permeability PE characterized by rapid onset, cellular damage and protein-rich pleural fluid. PE may not be mediated by adverse cardiovascular effects of xylazine and oxygen radicals are possibly involved in its etiology.
