Rat livers were flushed and stored for a maximum period of 24 hr at 4 degrees C, and tissue energetics, substrate, and anaerobic end-products were assessed; the group exhibiting the best results during storage was recovered in a 60-min period of warm reperfusion. Relative buffering capacities of the experimental solutions (measured over physiological pH range, in mM H+/L) were: UW, 4.1; histidine+UW, 9.8; Tris+UW, 19.0; bicine+UW, 22.5; tricine+UW, 26.8.

The purine base transport systems of wild-type and mycophenolic acid-resistant (MPAR) Tritrichomonas foetus have been characterized. Wild-type T. foetus has two carriers, one for hypoxanthine (Km = 0.7 +/- 0.3 mM, Vm = 80 +/- 20 pmol microliters-1min-1) and guanine (Km = 0.09 +/- 0.02 mM, Vm = 17 +/- 3 pmol microliters-1min-1), and a second for xanthine (Km = 0.6 +/- 0.2 mM, Vm = 25 +/- 5 pmol microliters-1min-1). Adenine transport was not saturable (k = 0.16 +/- 0.01 min-1) and therefore appears to enter the parasite by passive diffusion through the membrane. T. foetus MPAR has lost the hypoxanthine/guanine transporter. Xanthine and adenine transport are similar in wild-type and MPAR T. foetus. No purine nucleoside transporter could be identified.

Insulin-dependent diabetes mellitus is one of the leading causes of death world wide. Donor-derived pancreas and islet of Langerhans transplantation are potential cures, however, postmortem ischemia impacts islet quality. The murine βt3 cell line was used as a model to study apoptosis after hypothermic storage by comparing Unisol™ with Belzer's machine perfusion solution (BMPS) and the University of Wisconsin (UW) solution. The objective was to determine which of these solutions provided the best support for βt3 cells and which solution demonstrated the least amount of apoptotic activity. Several apoptosis markers were measured that included the translocation of phosphatidylserine, caspase activity, and the formation of DNA laddering. In addition, metabolic activity and membrane integrity were also measured. The results demonstrated that the three solutions behaved similarly during overnight cold storage at 4°C. However, Unisol was consistently better than UW solution and BMPS, demonstrating better cell viability and recovery, and lower levels of apoptotic activity when all three parameters were measured. These results demonstrated that apoptosis plays an important role in the survival of cells and tissues during cold storage. Development of solutions to help prevent or decrease the levels of apoptosis after cold storage will likely improve overall cell and tissue recovery and survival in a clinical setting.

One cause of ischemic brain injury is free radical formation during recirculation. Allopurinol inhibits xanthine oxidase, an important source of free oxygen radicals. It is known that allopurinol pre-treatment has a protective action during cerebral ischemia. In the present study we exposed slices from the rat hippocampus to 9 minutes of hypoxia to test whether it is sufficient that allopurinol is present in the tissue at the time of reoxygenation. Forty-six slices loaded with allopurinol (10(-5) M) prior to reoxygenation (during hypoxia) were compared to 34 control slices. The response of the pyramidal cell population to orthodromic stimulation was reduced in both groups and there was not a significant difference between the two groups.

Among all groups studied, grafts stored with Columbia University solution demonstrated the highest Pa O2 (355 +/- 25 mm Hg for Columbia University solution versus 95 +/- 22 mm Hg for Euro-Collins solution, P <.01, 172 +/- 55 mm Hg for University of Wisconsin solution, P <.05, 76 +/- 15 mm Hg for low-potassium dextran glucose solution, P <.01, and 82 +/- 25 mm Hg for Columbia University solution without cyclic adenosine monophosphate or nitroglycerin, P <.01) and the lowest pulmonary vascular resistances (1 +/- 0.2 mm Hg * mL-1 * min-1 for Columbia University solution versus 12 +/- 4 mm Hg * mL-1 * min-1 for Euro-Collins solution, P <.01, 9 +/- 2 mm Hg * mL-1 * min-1 for University of Wisconsin solution, 14 +/- 6 mm Hg * mL-1 * min-1 for low-potassium dextran glucose solution, P <.01, and 8 +/- 2 mm Hg * mL-1 * min-1 for Columbia University solution without cyclic adenosine monophosphate and nitroglycerin). These functional and hemodynamic improvements provided by Columbia University solution were accompanied by decreased graft leukostasis and decreased recipient tumor necrosis factor alpha and interleukin 1alpha levels compared with the other groups. In toto, these improvements translated into superior survival among recipients of Columbia University solution-preserved grafts (100% for Columbia University solution, 37% for Euro-Collins solution, P <.01, 50% for University of Wisconsin solution, P <.05, 50% for low-potassium dextran glucose solution, P <.05, and 13% for Columbia University solution without cyclic adenosine monophosphate and nitroglycerin, P <.01).
The stability of drugs commonly prescribed for use in oral liquid dosage forms but not commercially available as such was studied. Acetazolamide 25 mg/mL, allopurinol 20 mg/mL, azathioprine 50 mg/mL, clonazepam 0.1 mg/mL, and flucytosine 10 mg/mL were prepared in 1:1 mixture of Ora-Sweet and Ora-Plus (Paddock Laboratories), a 1:1 mixture of Ora-Sweet SF and Ora-Plus (Paddock Laboratories), and cherry syrup and placed in polyethylene terephthalate bottles. The sources of the drugs were capsules and tablets. Six bottles were prepared per liquid; three were stored at 5 degrees C and three at 25 degrees C, all in the dark. A sample was removed from each bottle initially and at intervals up to 60 days and analyzed for drug concentration by stability-indicating high-performance liquid chromatography. At least 94% of the initial drug concentration was retained in all the oral liquids for up to 60 days. There were no substantial changes in the appearance or odor of the liquids, or in the pH. Acetazolamide 25 mg/mL, allopurinol 20 mg/mL, azathioprine 50 mg/mL, clonazepam 0.1 mg/mL, and flucytosine 10 mg/mL were stable for up to 60 days at 5 and 25 degrees C in three extemporaneously compounded oral liquids.

The moderately protective effect of D-allose, which caused no clinical side effects, is encouraging. D-Allose had the best protective effect against neutrophil-related postischemic injury of the liver tissue, followed by allopurinol and superoxide dismutase. However, a more extensive study is needed to ensure the effects as well as the mechanisms of the effect of this rare sugar.
In vehicle-treated rats, intermittent hypoxia impaired acetylcholine-induced vasodilation compared to normoxia (+4 ± 4 vs. +21 ± 6 μm, p = 0.01). Allopurinol attenuated this impairment (+26 ± 6 vs. +34 ± 9 μm for intermittent hypoxia and normoxia groups treated with allopurinol, p = 0.55). In contrast, nitroprusside-induced vasodilation was similar in all rats (p = 0.43). Neither allopurinol nor intermittent hypoxia affected vessel morphometry or systemic markers of oxidative stress. Urinary uric acid concentrations were reduced in allopurinol- versus vehicle-treated rats (p = 0.02).
The UW solution perfusion group maintained better ATP levels than the EC solution group when the ischemic period was extended to 5 h. The perfusion pressure of 100 cm-gravity was more effective for preserving muscle viability than 40 cm-gravity with both EC and UW solutions.

Of 1380 patients, 139 (10%) had a diagnosis of gout or were prescribed allopurinol. They had more co-morbidities (7.0 vs 5.6; P<0.0001) and consumed more drugs (6.8 vs 5.0; P<0.0001). The CIRS (co-morbidity index) was worse in these patients (OR 1.28 95% CI 1.15-1.41). Multivariable regression analysis showed that only renal and heart failures were independently associated with gout/allopurinol intake. Moreover, this combined event was associated with an increased risk of adverse events during hospitalization (OR 1.66, 95% CI 1.16-2.36), but not with the risk of re-hospitalization, length of hospital stay or death.

This study examined the effects of ischemic preconditioning (IPC), allopurinol (Allo) or a combination of both on the extent of mitochondrial injury caused by hepatic ischemia/reperfusion (I/R). I/R increased the serum aminotransferase activity and the level of mitochondrial lipid peroxidation, whereas it decreased the mitochondrial glutathione level. Either IPC or Allo alone attenuated these changes with Allo+IPC having a synergistic effect. Allo increased the serum nitrite and nitrate level after brief ischemia. The significant peroxide production observed after 10 min of reperfusion after sustained ischemia was markedly attenuated by Allo+IPC. The mitochondria isolated after I/R were swollen, which was reduced by Allo+IPC. At the end of ischemia, the hepatic ATP level was lower and there was significant xanthine accumulation, which was attenuated by Allo+IPC. These results suggest that IPC and Allo act synergistically to protect cells against mitochondrial injury and preserve the hepatic energy metabolism during hepatic I/R.

65 patients (aged 18-85 years) with angiographically documented coronary artery disease, a positive exercise tolerance test, and stable chronic angina pectoris (for at least 2 months) were recruited into a double-blind, randomised, placebo-controlled, crossover study in a hospital and two infirmaries in the UK. We used computer-generated randomisation to assign patients to allopurinol (600 mg per day) or placebo for 6 weeks before crossover. Our primary endpoint was the time to ST depression, and the secondary endpoints were total exercise time and time to chest pain. We did a completed case analysis. This study is registered as an International Standard Randomised Controlled Trial, number ISRCTN 82040078.

Data were obtained through surveillance networks in France, Germany, Italy, and Portugal. Drug use before the onset of disease was compared in 245 people who were hospitalized because of toxic epidermal necrolysis or Stevens-Johnson syndrome and 1147 patients hospitalized for other reasons (controls). Crude relative risks were calculated and adjusted for confounding by multivariate methods when numbers were large enough.
A dose-response for canakinumab was not apparent with any of the four predefined dose-response models. The estimated canakinumab dose with equivalent efficacy to colchicine was below the range of doses tested. At 16 weeks, there was a 62% to 72% reduction in the mean number of flares per patient for canakinumab doses ≥50 mg versus colchicine based on a negative binomial model (rate ratio: 0.28-0.38, p≤0.0083), and the percentage of patients experiencing ≥1 flare was significantly lower for all canakinumab doses (15% to 27%) versus colchicine (44%, p<0.05). There was a 64% to 72% reduction in the risk of experiencing ≥1 flare for canakinumab doses ≥50 mg versus colchicine at 16 weeks (hazard ratio (HR): 0.28-0.36, p≤0.05). The incidence of adverse events was similar across treatment groups.
Study established that after the first three months of allopurinol use, there was statistically significant difference in the average value of uric acid compared to the patients' initial state. During the next three months of therapy no further statistically significant difference in average values of uric acid (p = 0,936) was detected, meaning that the desirable effects of drug use were achieved. Simultaneously, the values of triglycerides, cholesterol and LDL fractions in test subjects increased significantly (p > 0,05). The values of HDL fractions increased after three month therapy with allopurinol, but later their value remained constant. Atherogenic index increased significantly after three and six months of therapy, therewith retaining at upper limit of reference value.

To examine the management of gout in general practice in Townsville, Australia, and to explore comorbid conditions in patients with gout. Study will also explore how closely guidelines are being followed in managing gout. Retrospective chart review was conducted from May to November 2014 in three general practices in Townsville. Registers for patients were established by searching "gout" and "gouty arthritis". Three hundred and twenty-one patients were included in the study after excluding inactive patients, patients below age of 18 and patients with cancer. Main outcome measures were prevalence of comorbidities in gout patients, gout medications and adequate serum urate control (≤0.36 mmol/l). Multivariate logistic regression was used to study the relationship between serum urate level, comorbid conditions and lifestyle factors. Hypertension was the most common comorbid condition with 60.8 % of patients followed by obesity and dyslipidaemia. In terms of medication, 46.7 % of patients were on allopurinol, 12.8 % on indomethacin and 13.4 % on diuretics. Eighty-six percentage of patients had serum urate level (sUA) recorded in the previous year. Of these, 32.2 % had a serum urate level below or equal to 0.36 mmol/l. Moreover, 17.4 % of patients had lifestyle advice documented in chart. Male gender was the most influential factor in having poor uric acid control (p < 0.01), followed by not being on allopurinol (p < 0.01) and patients older than 50 years (p = 0.02). Management of gout in this study sample was not entirely concordant with guidelines. The study also suggests a need for possible tighter monitoring and allopurinol dosing regime in older, male patients.
