By Neil MacDonald Federal Technology Watch A nationally accredited military health program using some of the latest technology is to be adapted to meet the needs of West Virginia's underserved rural patients. "For far too long, rural health care has meant inferior health care, " said Sen. Robert Byrd, D-WVa. "That's unacceptable. Programs such as HEALTHeWV allow patients in rural areas to take a far more active role in their care which, in turn, helps to further the goal of health care equality." HEALTHeWV will use information technology from Walter Reed Army Medical Center's award-winning HEALTHeFORCES program for a disease outcomes management and preventive health services initiative to improve health care quality, cut costs See NTTC's Role in Health Care, page 5, for example, what is colchicine!

PA17 The Potential of Cyclodextrin in Developing Generic Buffers for the Separation of Steroids Y.Shakalisava, F.Regan Dublin City University, Dublin, Ireland The analytical interest in the determination of steroids is maintained at a high level. This is due to their physiological functions in the body and the potential danger in disruption of the endocrine system. This work shows the potential of cyclodextrin modified capillary electrophoresis CD-CE ; in the development of a generic buffer system for the separation of steroids. Steroids are known to form an inclusion complex with cyclodextrins [1]. Fundamental knowledge of equilibrium and the association constants of analysed compounds and ligand in the system is a powerful element in the understanding of that system and in discovering ways to evaluate it. The association constants of inclusion complexes were determined for a range of structurally related steroids and sulphobutyl--CD. The optimal conditions for separation were chosen for several case studies. The potential of the method is demonstrated in the example of a related steroid not examined in the original work, but having similar structural or physical characteristics to those studied. The association constant and other physical characteristics of the target compound were used in the determination of the optimum conditions of separation. Statistical evaluation of data is presented. 1. N. Sadlej-Sosnowska, J. Inclusion Phenomena and Molecular Recognition in Chemistry 27 1997 ; 31 and

Instillations of DEP alone and in combination with 200 g rat LPS. In a previous study 32 ; , we detected lipid derived free radical metabolites by intratracheal LPS dose of 500 g rat. We found also that using an LPS dose below 300 g rat would not yield free radical generation detectable by ESR spin-trapping technique. Therefore, in order to provide convincing evidence for the synergistic effect of DEP and LPS in this study, we chose a low LPS dose of 200 g rat which alone would not generate free radicals at ESR detectable level. As shown in Fig. 1A, neither LPS 200 g rat ; nor DEP given alone 20 mg kg ; gave an ESR spectra significantly above the control instillation. However, the combined instillation of DEP and LPS caused a marked increase in the six-line ESR spectrum of a radical adduct Fig. 1A, p 0.05 ; . For all further experiments, LPS at a dose of 200 g rat and DEP at a dose of 20 mg kg were used. Synergistic lung injury and neutrophilic inflammation by DEP + LPS in rats. For the animal model of lung injury caused by DEP we chose an intratracheal dose of 20 mg kg. Although there are reports that lower doses cause lung damage accompanied by free radical generation 29, 37 ; , we were not able to detect free radicals using spin trapping at doses below 20 mg kg data not shown ; . To determine the effect of DEP and LPS on lung injury, we evaluated the total concentration of protein in BAL fluid and lung specimens stained with hematoxylin and eosin 24 h after intratracheal instillation Fig. 2 ; . The instillation of LPS or DEP alone did not significantly change the protein concentrations in BAL fluid of the lungs as compared with vehicle administration alone. However, the combined administration of DEP and LPS resulted in a marked increase in the protein concentration in BAL fluid as compared to the LPS or DEP groups p 0.01 ; Fig. 2A.
The approach to treating gout in this patient population parallels that of most patients, albeit with a few precautions. Anti-inflammatory therapy should be initiated as soon as the diagnosis is made. There are several choices. Colchicie is effective for most patients. The dose may be titrated until gastrointestinal side effects occur. A typical starting dose is 0.6 mg every 6 h. At the appearance of diarrhea, abdominal cramping, or nausea, the dose may be reduced to 0.6 mg once or twice a day and continued for the duration of symptoms. The danger with colchicine resides in its ability to induce myoneuropathy 40 47 ; . reversible disorder, it may nevertheless be highly disabling. It should be suspected in any colchicine-treated patient developing weakness and an elevated serum creatine kinase level. The diagnosis may be confirmed by muscle biopsy, which reveals a characteristic vacuolated myopathy. Impaired renal function clearly enhances the risk for this complication, which may explain the number of reports occurring in the setting of renal transplantation 40, 41, 44 ; . For this reason, the Cleveland Clinic group has recommended the sparing approach to colchicine use in renal transplant patients outlined in Table 2 28 ; . Some patients are unable to tolerate even modest exposure to colchicine. One of our renal allograft recipients developed biopsy-proven colchicine myopathy while being treated for gout. This patient improved after cessation of colchicine therapy, but relapsed when challenged with a dose as small as 0.6 mg d. Nonsteroidal anti-inflammatory drugs NSAID ; are an effective alternative to colchicine in treating gouty arthritis. These agents can adversely affect renal hemodynamics in susceptible individuals, and may also cause hyperkalemia 48, 49 ; . Because these same effects occur in association with cyclosporine, NSAID must be used extremely cautiously in renal transplant patients, particularly those with compromised graft function 50 ; . One of the more "renal sparing NSAID" such as sulindac or a nonacetylated salicylate may be administered, but these are not always effective against a full-blown, established attack of gout. Clinicians using salicylates should be aware of their odd dose-dependent effects on uric acid and

It was also interesting to note that when asked about self-reported fitness level the majority of the adolescents rated their fitness level reasonably high i.e. an average of 6.2 on a 1-10 continuous scale ; . However, a significant minority of the respondents 25% ; had a `low fitness level'. It is interesting to note that a low self-reported fitness level was one of the factors that was positively correlated with a high depression score whereby those who had a low self-reported fitness level were almost twice as likely to report a high depression score. This finding is not surprising given that a substantial body of literature attests to the benefits associated with fitness and psychological health.2 Therefore, health promotion strategies to encourage fitness levels and exercise among adolescents may have a beneficial effect on the psychological health as well as the physical health of adolescents. Previous studies involving adolescents have shown that an important predictor of physical activity behaviour was participation in community sports.24 Therefore perhaps one potentially effective way to increase physical activity among these adolescents would be to facilitate greater access to community-based physical activity outlets such as fitness programmes designed specifically for adolescents. To help with this process, schools could establish links with community sports leaders so that students become more aware of the physical activity opportunities in their community, for instance, colchicine warfarin.

In institutional political science and the social scientific study of regulation and organizations more generally. We apply these methods to the review of new drug applications NDAs ; by the U.S. Food and Drug Administration FDA ; , a subject of increasing interest in contemporary medicine and politics. The enactment of the Prescription Drug User Fee Act PDUFA ; in 1992, and its revision in 1997 and 2002, imposed quite specific and somewhat flexible review time goals upon the FDA. We assess whether these review time goals "PDUFA clocks" ; which can be fruitfully viewed as deadlines with implicit penalties for their violation have influenced the timing of FDA decision making. We also ask whether drugs approved just before these PDUFA deadlines are subject to different post-market regulatory experiences than other drugs approved by the FDA. While the application here is quite specific, the methods have broader application, including to other products and applications reviewed by the FDA devices, vaccines, supplements ; , to other pharmaceutical regulators the European Medicines Evaluation Agency of the E.U., or Health Canada ; , and to other regulatory situations where delay is an important feature of the administrative landscape dam license renewal by the Federal Energy Regulatory Commission, for instance ; . A crucial feature of the present analysis is that the two statistical analyses are tied to one another in a flexible manner. The dynamic Cox hazard estimation offers semi-parametric statistical evidence that the PDUFA clock deadlines induce changes in FDA decision making, and the results of these hazard analyses inform the statistical analysis of postmarketing regulatory events. Using flexible statistical techniques to refine and yield the most comparable and controlled samples, we use this "before versus after" comparison to shed light upon the safety consequences of PDUFA deadlines. This paper serves as a technical companion to a shorter paper, Carpenter and Zucker 2006 ; , in which statistical evidence is presented for highly abrupt changes in FDA drug approval probabilities in the months just before and just after statutory deadlines occur. In addition to replicating and extending the results of that paper showing that drugs approved just before the deadlines have substantially different post-marketing experiences than those approved just after we also augment generalized linear models with other forms of observational analysis including nearest-neighbor matching ; to assess the robustness of causal inferences concerning deadline institutions and regulatory behavior. We begin empirically, by describing the user-fee law of 1992 and its amended versions passed in 1997 and 2002. We then elaborate a dynamic Cox model for estimating the effect of deadlines upon regulatory review timing, and apply these methods to FDA review times for new molecular entities. We then turn at least to generalized linear models for assessing the influence of the deadlines upon the quality of FDA choices, and examine the correlation of deadlines with post-marketing regulatory events such as drug withdrawals, relabeling, package and manufacturing revisions and other observable post-approval events.

NVP 12, 13 ; . While Zhou et al reported that body weight was not associated with NVP clearance 13 ; , in contrast, the authors found that higher body weight was associated with lower NVP level. This discrepancy may be explained by the different range of the body weight of the study patients. The patients in the present study had a mean body weight of 54.7 kg whereas 73.9 kg in the previous study. Body weight may have effects on the NVP levels in patients with lower body weight.

Guan, Department of Pharmacology, Zhongshan Medical College, Sun Yat-Sen University, Guangzhou, China] - EUR. J. PHARMACOL. 2006 548 1-3 ; - summ in ENGL Previously, it was found that total saponins from panax notoginseng inhibited Ca2 + influx coupling to activation of 1 adrenoceptor. This study was designed to investigate the effects of ginsenoside-Rd from total saponins of panax notoginseng on receptor-operated ROCC ; and store-operated SOCC ; Ca2 + channels in vascular smooth muscle cells using fura-2 fluorescence, whole cell patch clamp ion channel recording, radio-ligand-receptor binding, 45 Ca2 + radio-trace and organ bath techniques. It was found that ginsenoside-Rd reduced phenylephrine-induced contractile responses and Ca2 + influx in normal media without significant effect on these responses in Ca2 + -free media. Ginsenoside-Rd also decreased phenylephrine- and thapsigargin-induced inward Ca2 + currents, and attenuated thapsigargin- and 1-oleoy-2-acetyl-sn-glycerol OAG ; -induced cation entries that are coupled to ROCC and SOCC respectively. Ginsenoside-Rd failed to inhibit KCl-induced contraction of rat aortal rings and Ca2 + influx, and did not alter voltage-dependent inward Ca2 + current VDCC ; which was blocked by nifedipine. Also, ginsenoside-Rd did not change binding site and affinity of [3 H]-prazosin for 1 -adrenoceptor in the vascular plasma membrane. These results suggest that ginsenoside-Rd, as an inhibitor, remarkably inhibits Ca2 + entry through ROCC and SOCC without effects on VDCC and Ca2 + release in vascular smooth muscle cells. 2006 Elsevier B.V.

Athias, Laboratory of Experimental Cardiovascular Physiopathology and Pharmacology, Institute of Cardiovascular Research, University Hospital Center, 21079 Dijon, France] - EUR. J. PHARMACOL. 2006 548 1-3 ; - summ in ENGL Alterations of the microtubule network, which is involved in many vital processes, occur in several pathological conditions, such as cardiac ischemia. However, the connection between the microtubule assembly state and the factors affecting myocardial reperfusion injury, especially oxidative stress, is unknown. We aimed thus to study the effects of different tubulin ligands on the changes in the microtubule network and in several markers of cell injury and oxidative activity in cardiac muscle cells submitted to a reversible substrate-free, hypoxia-reoxygenation model of ischemia-reperfusion. The microtubule network was visualized by immunocytochemistry. Cell injury was evaluated via lactate dehydrogenase release and the mitochondrial function by the MTT test. Superoxide production was detected using dihydroethidium. The activity of NADPH oxidase and mRNA subunit expression were investigated. The microtubule disassembly induced by simulated ischemia was reversed by placing cardiomyocytes under normoxic conditions. This post-"ischemic" restoration of microtubule assembly was modulated by microtubule stabilizers taxol: paclitaxel ; and by microtubule disrupting drugs nocodazole, colchicine ; . In addition, nocodazole decreased superoxide anion production as well as NADPH oxidase activity and mRNA expression of the NADPH oxidase subunit p22phox. These results demonstrated that the "ischemia"-induced microtubule network alteration is reversible and suggest a possible relationship between "reperfusion"-induced reassembly of microtubules and free radical generation in post"ischemic" cardiomyocytes. 2006 Elsevier B.V.

Taxol binds to microtubules and blocks depolymerization. It is an important anti-cancer drug that works by blocking dividing cells in mitosis and triggering apoptosis. Taxol is used to stabilize microtubules for biochemical applications, such as purifying and assaying motor proteins Colchicine, nocodazole bind to unpolymerized tubulin and block polymerization. Cokchicine was used to treat gout, though it has been mostly replaced by anti-inflammatory drugs due to its toxicity. Nocodazole is more used in microtubule research. It enters cell rapidly, depolymerizing microtubules. Unlike colchicine, its effects are rapidly reversible by wash-out.
Prospective donors AIII ; Table 4 ; . Seronegative HSCT recipients should receive seronegative or leukocyte-depleted blood products AI ; . Seronegative autograft recipients are susceptible for primary CMV infection via blood products. Thus, seronegative or leukocyte-depleted blood products may be used to prevent transfusion-transmitted CMV infection CIII ; . Seronegative candidates and HSCT recipients who are sexually active and not in long-term monogamous relationships should use latex condoms during sexual contacts AII ; . Handling or changing diapers or wiping oral secretions from toddlers also represents a potential risk for CMV transmission to seronegative individuals and should therefore be avoided AII ; . Preventing disease or disease recurrence One of two strategies should be used to prevent CMV disease in allogeneic HSCT recipients between engraftment and day 100 after transplant AI ; Table 4 ; . The first strategy is to give ganciclovir prophylaxis from engraftment until day 100.2 An alternative strategy is to use virologic surveillance and administer ganciclovir for early evidence of subclinical CMV infection.3, 4 Tests used for this purpose include CMV blood cultures, the pp65 antigenemia assay, and DNA detection methods.5 Due to lower sensitivity, blood culture methods are generally not recommended. Limited data exist on other detection methods such as detection of pp67 mRNA and DNA by the hybrid capture method6 and no comparative study has been reported for preemptive therapy using these assays. Centers without access to highly sensitive CMV detection methods should use prophylaxis BII ; . In seronegative recipients with a positive donor, the incidence of CMV infection is only 15-20% when seronegative or leukocyte-reduced blood products are given. Thus, pre and doxycycline.
Colchicine protects against GalN-LPS-induced hepatitis in mice. As reported previously, intraperitoneal administration of 5 , ug Salmonella abortus equi LPS per kg to NMRI mice sensitized by 700 mg of GalN per kg led to induction of fulminant hepatitis within 8 h as assessed by determination of serum transaminases 27 ; . As indicated in Table 1, GalNLPS-injured mice released high amounts of TNF into the circulation as determined 1 h after challenge. Because a long period of time is needed for impairment of microtubular function and shortly before challenge a pharmacokinetic reload is necessary, we decided to pretreat animals with the microtubule disrupting agent colchicine 19 and 4 h before LPS challenge. Administration of 0.5 mg of colchicine per kg according to this regimen protected against GalN-LPSinduced hepatitis Table 1 ; . Compared with amounts in untreated controls, large amounts of TNF were still systemically present in colchicine-protected mice, even though the amounts were significantly smaller than in animals which had received LPS alone. These results prompted us to further investigate the protective effect of colchicine against TNF-mediated cytotoxicity. TNF-at-induced hepatitis as well as LPS-induced macrophage-mediated lethality in GaiN-sensitized C3H HeJ mice is prevented by coichicine. i.v. administration of 15 , ug recombinant murine TNF-at per kg instead of LPS to GalNsensitized mice resulted in a fulminant hepatitis within 8 h 25; cf. Table 2 ; . In vivo, TNF toxicity was also induced by i.v. injection of LPS-stimulated bone marrow-derived macrophages from LPS-responsive C3H HeN mice to GalNsensitized LPS-resistant C3H HeJ mice 12; cf. Table 2 ; . The macrophages produced large amounts of TNF upon LPS stimulation Table 3 ; . To exclude the possibility that the colchicine preparation contained minute amounts of LPS which could have induced tolerance against TNF toxicity 11 ; we performed the following in vivo experiments with the LPS-resistant C3H HeJ mouse strain. The results in Table 2 show that preventative pretreatment of mice with colchicine protected against TNF-cx-induced hepatitis as well as against LPS-induced, macrophage-medi.
Culture 66-72 hours ; and by the direct bone-marrow technic described previously.' In the latter method the cells are neither exposed to culture conditions nor to colchicine and, thus, the results represent the in vivo status of the marrow cells. The chromosomes were assigned to various groups, combining the numerical and alphabetical labels, 8'9 as done in previous publications.3'5 Leukocyte alkaline phosphatase was determined according to the technic described by Kaplow, 1# and the results were based on the "scoring" method suggested by him.
