BEHAVIOR OF THREE RAT STRAINS IN THE MORRIS WATER MAZE I. Stefanckov, M. Hrub, M. Hybelov, L. Trneckov, S. Hynie, V. Klenerov Dept. of Pharmacology, First Medical Faculty, Charles University, Prague, Czech Republic The Morris Water Maze is a commonly used device to investigate spatial learning and memory in laboratory rodents. During the last 20 years it has become one of the most frequently used laboratory tools in behavioral neuroscience 1 ; . In our experiments, the main aim was to test the effect of rat strain on the behavior of rats with different activity of hypothalamo-pituitary-adrenal HPA ; axis; these experiments are an extension of our behavioral studies investigating stressor specific changes and the interaction of stressors and amphetamine AMPH ; 2, 3 ; . We used three male rat strains, namely Wistar Velaz, Prague ; , Sprague-Dawley and Lewis rats Charles River Laboratories, Germany the latter are known to have a deficient HPA axis activity and reveal several biochemical and behavioral differences from other strains. We used a typical water maze with an automatic registration of rat movement. Rats were trained to find an invisible escape platform from 4 cardinal points. The rat performance was expressed as mean latency and distance to reach the platform, and several other parameters were calculated. More advanced parameters path length efficacy, latency, heading accuracy, bearing accuracy, tortuosity, thigmotaxis, segment and rings used ; were analyzed by using computer program TRAM. Wistar rats learned the task during 4-5 days. Both average escape latency and distance were different in other two rat strains; Lewis rats revealed slower and Sprague-Dawley rats faster learning than Wistar rats. The extension of learning up to 18 days showed that Lewis rats never reached performance comparable to Sprague-Dawley rats. Our results provide another support for idea of strain differences in learning ability of rats and represent basis for our further experiments testing the interaction of various stressors with psychostimulants, like amphetamine. 1.

HYPOVENTILATION AND AMPLITUDE CHANGES OF ECG IN THE DEPENDENCE ON THE LIGHT DARK CYCLE IN FEMALE WISTAR RATS J. Stimmelov, P. Svorc, I. Bracokov., Z. Richtrikov Department of Physiology, Medical Faculty, Safarik University, Kosice, Slovak Republic Hypoventilation HV ; as one of disorders of normal ventilation decreased the electrical stability of the heart and increased the vulnerability to the ventricular arrhythmias. Therefore the aim of this study was to investigate the effect of 20 minute HV on amplitudes of ECG in the dependence on the alternation of the light and the dark cycle in female Wistar rats. The experiments were performed in the anesthetized ketamine-100 mg kg i.m. + xylazinum-15 mg kg i.m, Lciva, Praha ; female rats adapted to the light-dark regime 12: hours. The rats were subjected to the following condition of ventilation: 1 ; intact group without artificial ventilation, 2 ; group after tracheothomy and thoracothomy with 5 min artificial ventilation parameters of ventilation: 40 breath min., 1 ml 100 ml g of body weight ; , 3 ; group after 20 minute of HV parameters of ventilation: 20 breath min., 0.5 ml 100 g of body weight. The ECG parameters were evaluated from the 2nd limb lead of ECG. The significance of differences were evaluated by Students t-test. On the strength of comparison of ECG amplitudes in the light and the dark phase, the following significant changes were found, in the intact group, with the higher P wave amplitude 0.06 mv vs. 0.032 mV p 0.01 ; , and the lower R wave amplitude 0.41 mV vs. 0.56 mV p 0.01 ; in the dark phase. In the 2. group, the lower T wave amplitude 0.02 mV vs. 0.021 mV p 0.5 ; in the dark phase and in the 3. group, the higher T wave amplitude 0.19 mV vs. 0.12 mV p 0.05 ; only after 15 min HV in the dark phase. It is concluded that prolonged hypoventilation in the light and the dark phase of the rat regime day has non-unequivocal influence to changes of ECG amplitudes.
What is Ecstasy? Ecstasy is 3, 4-methylenedioxymethamphetamine MDMA ; . It combines the chemical properties of Methamphetamine speed ; with the hallucinogenic properties of Mescaline. Although Ecstasy can be purchased as a powder it is usually sold as a pill in a variety of colors with imprinted logos or symbols. The various colors and symbols help users identify which pills they like and dislike. Ecstasy is typically ingested orally as a pill but can be snorted or injected intravenously. Someone who is high on Ecstasy is said to be "Rolling." Ecstasy, as well as, GHB, Rohypnol, Ketamine, Methamphetamine, and LSD have become increasingly popular over the last few years among young adults and have been referred to as Club Drugs. It's the most commonly used drug in the club drug family. Ecstasy, alone and in combination with other drugs, has been associated with lethal cardiac dysrrythmias fatal irregular heart beat ; . Ecstasy Popularity Increased by The Media and Internet Ecstasy's popularity has increased because the media and the internet have portrayed it as a euphoric love drug that can help solve all problems in a single night without any dangers or negative side effects. Ecstasy is said to make the user feel euphoric, happy, empathetic, and in touch with the people around them.
In the case of equation 2.3b. To ensure regression, drug doses or radiation intensity must be at least of the order of C kC This will make x 0 . that case the system passes to a regime like that in figure B.1, where autoregression occurs. After treatment culmination, it is natural to consider that the system restores its original characteristics, returning to the original regime. But the tumor was eliminated, as a synergy between the treatment and the absorbing property P0 , and no further growth occurs. The model 2.3 ; predicts that under a certain level of therapy, the tumor will shrink to zero. There is clinical experience which is contradictory to this prediction of the model, since certain treatment applications induce tumor shrinking to microscopical tumors Schuck et al., 2002; Partridge et al., 2000; Zeltzer et al., 1999 ; , and not to auto-regression. Another description qualitatively compatible with the observations is necessary, for example, ketamine doses.

Responding to a patient request for PAS is an important, and complex, clinical skill. These clinical discussions occur amid profound moral controversy, the emotions engendered by death and dying, and the technical complexities of contemporary medical care. Our patient and family accounts reveal many missed opportunities for clinicians to engage in therapeutic relationships involving discussions about PAS, dying, and end-of-life care. Clinicians responding to patients requesting PAS need communication skills that will enable them to discuss PAS and dying openly, an ability to talk about dying in a patient-centered way, and palliative care expertise. They also need expertise in setting reasonable expectations, individualizing pain control, and providing accurate information about the lethal potential of medications.

Phantom pain.21 68 Novel anticonvulsants such as lamotrigine and gabapentin may also prove to effective in phantom pain. Lidocaine and its oral congener mexiletine are used in different neuropathic pain conditions.52 I.v. lidocaine was reported to be effective in neuropathic pain.8 In an openlabel study, mexiletine produced pain relief in 18 of patients with phantom pain.12 Calcitonin may be effective in phantom pain. In a doubleblind, crossover study, Jaeger and Maier demonstrated that i.v. calcitonin was effective in phantom pain when used in the early post-operative period.35 The effect of NMDA receptor antagonists have been examined in different neuropathic pain conditions, including phantom pain.58 61 87 In double-blind, placebocontrolled study, i.v. ketamine reduced pain, hyperalgesia and `wind-up' like pain in 11 amputees with stump and phantom pain.58 Memantine is another NMDA receptor antagonist available for oral use. In a recent double-blind, crossover trial, patients with pain following amputation n 15 ; or nerve injury n 4 ; were randomized to receive memantine or placebo in a 5-week treatment period. A washout period of 4 weeks was followed by another 5-week treatment period. Memantine, at a daily dose up to 20 mg, failed to have an effect on spontaneous pain, allodynia and hyperalgesia.61 Opioids were previously thought to be ineffective in neuropathic pain. Controlled studies are still lacking. However, presently, many feel that some patients can benet from opioids with a limited risk of drug dependence.6 14 The analgesic effect of oral and intrathecal opioids in phantom pain has been described by several authors.34 65 90 Tramadol is an analgesic with both monoaminergic and opioid activity and it may prove to be an alternative to strong opioids as tolerance and dependence during long-term treatment with tramadol appears to be uncommon. NSAIDs and paracetamol are considered to be ineffective in phantom pain by most practitioners. A large number of other treatments, for example, betablockers, 1 topical application of capsaicin, 74 various anaesthetic blocks50 94 have been claimed to be effective in phantom pain but none of them have proven to be effective in well-controlled trials and levoxyl.

Of TGZ at the dose of 400 mg day for 12 months could not lessen the magnitude of macroalbuminuria 10 ; . In the present study, PGZ 30 mg day could effectively reduce urinary protein in type 2 diabetic patients with macroalbuminuria Table 3, Fig. 1, 2 ; . The disparity between the two studies might be caused by the larger number of participants in the present study n 40 vs and the difference in the TZD drugs used PGZ vs TGZ ; . In this regard, TGZ has been withdrawn from the market since 2002 because of the serious hepatotoxicity of the drug. The approximately 40% reduction in urinary protein excretion by PGZ in the present study are comparable to the values of 26 to 55% reduction from angiotensin converting enzyme inhibitors and angiotensin receptor blockers in previously reported studies in type 2 diabetic patients with overt nephropathy 14-16 ; . At present, there are no available data regarding the effect of TZD on TGF- in diabetic patients. Previous studies have shown that urinary rather than blood levels of TGF- are correlated with the activity of DN 17, 18 ; . The present study demonstrated that, in type 2 diabetic patients with overt nephropathy, PGZ could lessen urinary TGF- excretion by 48%. This magnitude of reduction is, of interest, greater than the figures of 23 to 39% decrease by angiotensin II receptor blocker in recent studies in type 2 diabetic patients with overt nephropathy 19 ; and in proteinuric renal diseases 20 ; . The pathologic hallmark of DN is increased extracellular matrix in glomerular basement membrane and mesangium, resulting in microalbuminuria and proteinuria 2 ; . TGF- appears to play a central role in this process. In agreement with previous works 13, 21, 22 ; , the present study has demonstrated that urinary type IV collagen excretion is increased in DN. The effect of PGZ on type IV collagen, however, has never been determined in diabetes. In the present study, PGZ could reduce the amount of urinary type IVcollagen by 35% while the levels were increased by 51% in the control group. The statistical significance, however, was nearly but not attained. This might be caused by the small number of subjects. The magnitude of urinary type IV collagen reducing the ability of PGZ, however, is still impressive. Taken together, in type 2 diabetes with macroalbuminuria, PGZ could reduce the synthesis of TGF- and type IV collagen, leading to improved renal pathology and, consequently, decreased proteinuria. Although glycemic control in the PGZ group seemed to be better than the control group, it did not reach statistical significance. Moreover, there were no, for example, ketamine facts.

Some of these questions will be addressed, but probably not answered, in this session. A109 Is D-dimer Testing Ready for Clinical Application? H Bounameaux Division of Angiology and Hemostasis, University Hospitals of Geneva, Geneva, Switzerland In the past fifteen years, plasma assays of several markers of activation of plasma coagulation and or fibrinolysis have been made available for clinical use, including D-Dimer DD ; , a specific degradation product of crosslinked fibrin, that can be measured using various immunoassays enzyme-linked immunoassay, ELISA, or latex agglutination tests ; . Its widespread use has been made possible only in recent years with the development of rapid assays that allowed result delivery within one hour or less after blood sampling. However, the heterogeneity of the assays has raised uncertainty among clinicians and called for rigorous evaluation and standardization of the various tests. Uncertainty was further increased because the usefulness of the test was also found to be dependent upon the populations to which it was applied, due to variations in test specificity. Nonetheless, a few commercial assays could achieve the following, successive validation steps: 1 ; technical description; 2 ; comparison with an established diagnostic standard, and, above all, 3 ; use in so-called management trials. In such trials, patients are followed-up for 3-6 months after the diagnosis of deep vein thrombosis DVT ; or pulmonary embolism PE ; has been made, and the safety of the diagnostic test or strategy is given by the patients' outcome, i.e. the 3-month thromboembolic risk. The 3-month thromboembolic risk in patients suspected of DVT PE and a negative DD test has been shown to be 2% or less, which is very similar to that observed in patients with a negative phlebogram, or a negative pulmonary angiogram, or a normal perfusion lung scan. Additional features of DD testing in patients clinically suspected of DVT PE include 1 ; its higher utility for ruling out DVT PE in younger patients compared to older individuals ; , 2 ; and in outpatients compared to patients hospitalized 3 ; its potential to predict or rule out recurrent DVT PE. In conclusion, DD testing has emerged in recent years as a definite aid in the diagnostic approach of venous thromboembolism, since it can safely rule out DVT PE in a substantial proportion 30% or more ; of outpatients clinically suspected, especially if combined with a low when using less sensitive DD assays ; or low-intermediate highly sensitive tests ; clinical probability of having the disease.

As an adjuvant to opioids for the treatment of postoperative pain, IV and epidural ketamune has an opioid sparing effect Subramaniam et al 2004, Level I ; . Best effects were seen when ketsmine was given as a continuous IV infusion, while there was no evidence supporting the addition of kwtamine to PCA morphine. Kehamine side effects were not apparent at the low doses used. In spite of an opioid sparing effect, no reduction of opioid-related side effects could be shown. In patients with severe pain that was incompletely relieved by morphine, the addition of ketamine to the morphine regimen provided rapid, effective and prolonged analgesia Weinbroum 2003, Level II ; .

A retrospective study of conventional antipsychotics in elderly patients found they were not safer than the atypical antipsychotics. The authors suggest the older agents be added to the FDA's Public Health Advisory regarding the increased risk for death in elderly patients with dementia. Methods: Data was extracted from a state-funded prescription plan for those aged 65 years for all new prescriptions for a conventional or atypical antipsychotic between 1994 and 2003. Nearly 23, 000 prescriptions were identified and included in the analysis. About 40% of prescriptions were for conventional agents and 60% for atypicals. Mortality was assessed during the 180 days after a new prescription. This time period was chosen to correspond with the period used in the FDA's recent analysis of atypical antipsychotics. The analysis was adjusted to account for a large number of potentially confounding variables, including: demography; clinical factors; individual physicians' preference for novel or typical agents; and calendar time to account for improvements in health care over the study period and

Several other medications with central nervous system effects have been used to treat TN, with varied success Table 2 ; . Pimozide is a neuroleptic that has shown significant relief of pain when compared with carbamazepine in a double-blind crossover trial by Lechin et al.20 Patients in this study had been diagnosed as having TN for at least 2 years and were treated with carbamazepine or pimozide. Adverse effects were common with pimozide, but mild, and no patients stopped the treatment because of side effects. Lamotrigine is an anticonvulsant with an action similar to that of carbamazepine, but with fewer side effects. A small noncontrolled study of patients who could not tolerate carbamazepine showed response without the side effects associated with carbamazepine.21 A controlled trial is needed to confirm this benefit. Tizanidine hydrochloride has neurochemical activity similar to that of baclofen and carbamazepine. A double-blind crossover study by Fromm et al22 evaluated its efficacy in patients with TN who were not responding to carbamazepine and found short-term improvement, with recurrence of pain in 1 to months. Other drugs include valproate sodium, racemic ketamine, proparacaine hydrochloride, and topical capsaicin cream. Valproate sodium was beneficial in a small group of patients studied by Peiris et al.23 Racemic ketamine, an anesthetic, showed some benefit when treating acute pain but was ineffective for pain lasting more than 5 years.24 The use of topical ophthalmic anesthet.

LENTICULOSTRIATAL DISEASES idebenone73 did not evidence any slowing of HD progression. d-alpha-tocopherol 3, 000 IU per day improved neurological symptoms early in the course of HD.74 Treatment with coenzyme Q10 reduced elevated cortical lactate concentrations in patients with HD, although clinical correlates were not studied.75 Ciliary neurotrophic factor demonstrated a protective effect against quinolinic acidinduced striatal degeneration in a monkey model of HD.76 Movement disorder treatment attempts have yielded mixed results. Optimal reduction of chorea with haloperidol was obtained at doses of 1.510 mg day 25 ng ml ; , whereas higher doses rarely produced additional benefit.77 Under double-blind placebo-controlled conditions, apomorphine actually improved chorea and motor impersistence, 78 clozapine variably improved chorea but worsened functional capacity, 79 and piracetam worsened chorea.80 Cannabidiol failed to alter chorea in a randomized double-blind placebo-controlled crossover study.81 Milacemide, a glycine prodrug, affected neither chorea nor cognition under double-blind placebo-controlled conditions.82 Neuropsychiatric treatment data are limited by a paucity of controlled trials.62 There are no specific treatments for the cognitive disorder of HD. Fluoxetine failed to improve cognition, functional capacity, or neurological status in a randomized double-blind placebo-controlled study in nondepressed patients with HD, although there was a slight improvement in agitation and in need for routine.83 Ketamine, an N-methyl-D-aspartate NMDA ; receptor antagonist, worsened memory and exacerbated psychiatric symptoms in a doubleblind placebo-controlled study involving patients with HD.84 Sertraline was effective in 2 consecutive cases against irritability and violent behavior.85 Propranolol is reported to relieve aggression associated with frustration and impatience in HD.86 Anecdotal evidence also supports the utility of buspirone in aggression.87, 88 Psychotic features may be either responsive or refractory to neuroleptic treatment.53 There is some evidence that clozapine may be particularly efficacious in psychosis89, 90 and that delusions may be more responsive to neuroleptics than hallucinations, 62 but more data are needed. Although mood stabilizers in HD require study, lithium rarely has been considered to be effective in treating bipolar disorders associated with HD.62 Major depression in HD is thought to be undertreated, 91, 92 presumably due to underrecognition. Tricyclic antidepressants and selective serotonin reuptake inhibitors SSRIs ; are regarded as first-line treatments for depression, 53, 62, 93 and patients with HD seem to respond to antidepressant treatment in a manner similar to patients with primary depression, although appropriate studies are lacking.53 Monoamine oxidase inhibitors may be useful for patients not responding to firstline agents.94 Augmentation of fluoxetine with deprenyl led to beneficial mood, motor, and behavioral effects in 1 patient.95 Delusional depression predicted the most favorable response to ECT among 5 depressed patients with HD.96 There is some evidence that medroxyprogesterone and leuprolide may be useful in reducing sexual disinhibition in HD.97 Although there are several descriptions of family therapy in HD, controlled outcome data are lacking.98 Opportunities for Further HD Research 1. Effects of CAG repeat length. The effect of HD gene CAG repeat length on disease progression and neuropsychiatric symptoms requires clarification. Heritability of neuropsychiatric phenomena. Definition of the heritability of neuropsychiatric phenomena such as OCD ; in kindreds with HD may distinguish those at risk and improve our understanding of these phenomena. Prevalence of psychiatric disorders. Determination of the prevalence of anxiety disorders by use of standardized diagnostic criteria is needed. Replication of prevalences of psychiatric disorders across different clinical settings is needed to determine the generalizability of earlier studies, as well as the effects of ascertainment and sample biases in previous studies. Correlates of psychiatric disorders over disease course. Elucidation of neuropathological correlates of psychiatric disorders and their evolutionary time courses in relation to HD progression would facilitate our understanding of the basal ganglia circuitry mediating these conditions. Functional imaging correlates of psychiatric disorders. Additional correlation of functional imaging data with particular psychiatric sequelae would be useful, as would further characterization of the differences among subjects with HD and depression, HD without depression, and primary depression without HD. Neuroprotective agents. Controlled treatment trials of the effects of neuroprotective agents against HD progression, employing larger sample sizes, are indicated. Such trials may allow detection of subtle protective effects not evident in previous studies. Pharmacologic interventions. Controlled treatment trials of neuropharmacologic and psychopharmacologic interventions in HD are needed. This is especially true of the cognitive disorder, which cur.
Abstract With the increasing life expectancy, osteoporosis is becoming a major worldwide health problem. The magnitude of the disease may become larger in developing countries, more particularly in the Middle East region where the prevalence of low bone mass is higher than in western countries. Although several local organizations and countries have developed guidelines for osteoporosis, no previous regional guidelines have been developed encompassing all Middle-Eastern and North African countries. The present document reviews all the regional published data on bone mineral density, risk factors, fracture prevalence and vitamin D status. It also gives simple recommendations applicable to all these countries. This document was endorsed by leading members of all the different regional countries including, Iran, Egypt, Tunisia, Jordan, Palestine, Syria, Iraq, Libya, Oman, Kuwait, Saudi Arabia and Bahrain. Keywords: Middle East, North Africa, Consensus, Osteoporosis, for example, ketamine info.

No scientific validity; unnecessary animal use: The number of repetitions the monkeys were made to do on the same tasks seems highly excessive. The training alone for the experiments took 2400-5700 trials for the first task and 4 months of trials for the second task. The monkeys took this long to learn the tasks, even before the lesions, implying that it was not a suitable task. The humans in the Drepper et al experiment certainly did not take anywhere near this long to learn the task, even with lesions in their cerebellum, emphasising again the differences between human brains and the monkey's brains. The use of monkeys as a model for this human condition has no scientific validity.

Subjects Subjects were 36 patients who received ketamine anesthesia in a retrospective review of all 723 patients who received index ECT treatment at Duke University Medical Center from 1989 through 1998 following informed consent. Six subjects who received ketamine anesthesia were not included in the study because they received a mixture of ketamine and low-dose methohexital and there is evidence that in the low-dose range methohexital may have proconvulsant properties.19, 20 One subject who received ketamine had received it at every treatment and thus could not be included. Of the 36 subjects, 17 were men and 19 were women, and the mean age was 67.6 years SD 16.0 ; . Nineteen had unipolar major depression, 15 had bipolar depression, and 2 had schizoaffective disorder, depressed DSM-III-R ; . Post-treatment reorientation time was studied as a measure of cognitive side effects.12 These assessments were performed on all of the subjects; however, we were able to obtain complete reorientation time data from the medical records for only 14 of the subjects. All of these 14 subjects had no evidence of neurologic disease on the basis of history and neurologic exam.
