From: ironjustice on 31 Jul 2008 10:00 "This field is in sore need of a success story," "Methylene blue has been in use for decades" Slowing mental ravages of Alzheimer's disease Well-known drug may combat effects, researchers say By Jeremy Manier | Chicago Tribune reporter July 31, 2008 Editor's note: Due to a production error, this story from Wednesday's newspaper did not run in full. This is the complete text. Hope is often scarce in research on Alzheimer's disease, but a study released Tuesday at a Chicago medical conference offered tentative hope for a new way of slowing elderly patients' mental decline. The preliminary study of 321 Alzheimer's patients from Singapore and Britain found that an old drug, previously used for urinary tract infections and other ailments, reduced the patients' rate of mental loss by 81 percent, based on a standard measure of cognitive performance and memory. The results require further confirmation, but whatever the outcome, some experts are intrigued by the drug's novel way of attacking the disease. Scientists say the medication, which goes by the commercial name rember, may work by dissolving tangles of a protein that collects in the brain cells of Alzheimer's patients. If true, the therapy could be the first to stave off an underlying cause of Alzheimer's disease, unlike current treatments such as Aricept, which provide only temporary relief of symptoms through their effect on brain compounds that are important in cognition. "The effect size is pretty large for drugs of this class," said Dr. Raj Shah, an Alzheimer's specialist and medical director of the memory clinic at Rush University Medical Center. Researchers presented the findings Tuesday at the 2008 Alzheimer's Association International Conference on Alzheimer's Disease, being held this week in Chicago. Other Alzheimer's treatments have shown early signs of promise but failed to deliver in clinical trials, making experts cautious about reading too much into Tuesday's findings. For example, numerous drugs now in development attempt to take aim at the plaques of beta-amyloid protein that develop among the brain cells of many Alzheimer's patients, but some of the outcomes have been disappointing. One such drug, tarenflurbil, which had promising results in an early- phase study, turned out to have no significant effect on the disease when tested in a larger clinical trial, researchers reported Tuesday. "This field is in sore need of a success story," said Dr. Marsel Mesulam, director of the cognitive neurology and Alzheimer's disease center at Northwestern University. Unlike drugs aimed at beta-amyloid, rember is meant to dissolve an abnormal protein called tau, which many experts had thought would be an elusive target for Alzheimer's treatments. Some theories suggest the tangles of tau protein that form in patients' brain cells could cause the symptoms of the disease by hampering chemical communication in the brain. It's also possible that the protein tangles are merely byproducts of a deeper problem that is the real source of cognitive decline. Study leader Claude Wischik of Aberdeen University's Institute of Medical Sciences has spent two decades tracing the role of tau protein tangles in Alzheimer's disease. He said he agrees that further tests are needed to confirm the preliminary results, but he's encouraged by the findings so far. "We've shown you can arrest disease development by targeting the protein tangle," said Wischik, who is also chairman of TauRx Therapeutics, which hopes to market the new treatment if it's successful. The drug Wischik tested is a purified form of a substance commonly known as methylene blue, which has been in use for decades as a treatment for numerous conditions, including urinary tract infections and carbon monoxide poisoning. Many patients on the drug report that their urine turns blue, but Wischik said so far the drug appears safe. Although in principle it would be possible for doctors to use the common version of the drug in patients before testing is complete, Wischik and other experts said that would be unwise. Among other problems, doctors who prescribed the drug on their own without proof that it works could be open to lawsuits if patients developed bad side effects, experts said. Wischik said that if further tests of the compound show promise, the treatment could be available for general use by 2012 or 2013, depending on how quickly the drug moves through regulatory hurdles in the U.S. and in countries overseas. jmanier(a)tribune.com ------------------------------------------ This study showed people began to remember old songs .. with lecithin a plant oil.

Results of a placebo-controlled study on the efficacy and tolerability of lecithin fluid in patients with impaired cognitive functions] Volz HP, Hehnke U, Hauke W. Krankenhaus fur Psychiatrie, Psychotherapie und Psychosomatische Medizin, Schloss Werneck. Lecithin, a precursor of the neurotransmitter acetylcholine, has a positive effect on brain and memory functions. In a prospective, randomized, double-blind study, the effect of buerlecithin fluid (BLF) was investigated in comparison with placebo in patients with mild cognitive disorders. A total of 96 ambulatory patients (> 55 years) were admitted to the study. Treatment duration was 84 days. In both treatment groups, a clear improvement in all the cognitive parameters tested was seen. The main target measure, the overall Sandoz Clinical Assessment Geriatric (SCAG) score improved by 18.7 (test substance) and 16.4 (placebo) points (p = 0.1620). A statistically relevant improvement of the secondary target parameter, response in the SCAG score, was achieved with BLF (85.4%) in comparison with placebo (62.5%) (p = 0.018). Furthermore, BLF demonstrated significant superiority in a number of the other target measures. The study also confirmed the very good tolerability of BLF.

Am J Psychiatry 1979 Nov;136(11):1458-60 Treatment of tardive dyskinesia with lecithin. Jackson IV, Nuttall EA, Ibe IO, Perez-Cruet J. Six patients with moderate or severe tardive dyskinesia participated in a 14-day double-blind crossover comparison of placebo with 50 g/day of lecithin. There were no side effects, and Abnormal Involuntary Movement Scale (AIMS) ratings of videotaped examinations indicated significant improvement in the dyskinesias of all subjects during the lecithin trial, even with concomitant administration of a constant dose of neuroleptic medication to five patients. ---------------------------------- Choline and lecithin in the treatment of tardive dyskinesia: preliminary results from a pilot study. Am J Psychiatry 1979 Jun;136(6):772-6 Gelenberg AJ, Doller-Wojcik JC, Growdon JH. Tardive dyskinesia is thought to reflect increased dopaminergic activity of the central nervous system. To compensate for this by increasing CNS cholinergic tone, the authors administered oral choline and its natural dietary source, lecithin, to 5 men with mild to severe tardive dyskinesia in a nonblind trial. Both choline and lecithin increased serum choline levels and improved abnormal movements in all patients. Lecithin had fewer adverse effects. ----------------------------- Lecithin consumption raises serum-free-choline levels. Lancet 1977 Jul 9;2(8028):68-9 Wurtman RJ, Hirsch MJ, Growdon JH. Consumption of choline by rats sequentially increases serum-choline, brain-choline, and brain-acetylcholine concentrations. In man consumption of choline increases in levels in the serum and cerebrospinal fluid; its administration is an effective way of treating tardive dyskinesia. We found that oral lecithin is considerably more effective in raising human serum-choline levels than an equivalent quantity of choline chloride. 30 minutes after ingestion of choline chloride (2-3 g free base), serum-choline levels rose by 86% and returned to normal values within 4 hours; 1 hour after lecithin ingestion, these levels rose by 265% and remained significantly raised for 12 hours. Lecithin may therefore be the method of choice for accelerating acetylcholine synthesis by increasing the availability of choline, its precursor in the blood. --------------------------------- The use of cholinergic precursors in neuropsychiatric diseases. Am J Clin Nutr 1982 Oct;36(4):709-20 Rosenberg GS, Davis KL. Preclinical data suggest that cholinergic precursors such as choline or lecithin, increase levels of acetylcholine in specific brain structures, and under certain conditions may enhance cholinergic neurotransmission. A variety of neuropsychiatric diseases including tardive dyskinesia. Huntington's chorea, ataxias, Tourette's syndrome, schizophrenia, affective illness, and senile dementia of the Alzheimer type, has been implicated with a general underactivity of central cholinergic mechanisms. Recent studies have investigated the possibility that cholinergic precursor loading strategies may provide viable treatments for these disorders of presumed cholinergic underactivity. Extensive data demonstrate that the symptoms of tardive dyskinesia can be reduced by choline or lecithin, whereas investigations in other disorders have met with mild success, at best, or are still in preliminary stages. Further controlled studies with choline or lecithin using broader dose ranges, longer durations of treatment, and concomitant administration of agents which may increase the release of acetylcholine are warranted. ------------- This article speaks to the oxidation in the brain.

Prog Neuropsychopharmacol Biol Psychiatry 2003 Feb;27(1):135-40 Burger ME, Alves A, Callegari L, Athayde FR, Nogueira CW, Zeni G, Rocha JB Departamento de Fisiologia, Centro de Ciencias da Saude, Universidade Federal de Santa Maria, 97105-900, RS, Santa Maria, Brazil Reserpine-induced orofacial dyskinesia is an alleged animal model of tardive dyskinesia whose pathophysiology has been related to striatal oxidative stress. In the present investigation, the authors examined whether ebselen, an antioxidant organochalcogen with glutathione peroxidase-like activity, changes the behavioral and neurochemical effect of acute reserpine administration. Reserpine injection for 3 days every other day caused a significant increase on the tongue protrusion frequency and ebselen (30 mg/kg ip for 4 days, starting 1 day before reserpine) reversed partially the effect of reserpine (P<.05). Reserpine- and reserpine+ebselen-treated groups displayed an increase in vacuous chewing frequency when compared to control and ebselen-treated groups (P<.05) Reserpine increased the duration of facial twitching and ebselen reversed partially the effect of reserpine (P<.01). Reserpine increased significantly the thiobarbituric acid-reactive species (TBARS) levels, and ebselen reversed the effect of reserpine on TBARS production in rat striatum. The results of the present study clearly indicated that ebselen has a protective role against reserpine-induced orofacial dyskinesia and reversed the increase in TBARS production caused by reserpine administration. Consequently, the use of ebselen as a therapeutic agent for the treatment of tardive dyskinesia should be considered. PMID: 12551736, UI: 22440265 Who loves ya.

Methods: 16 rabbits were randomly assigned either to group M (n = 8; receiving MB, intervention group) or group C (n = 8; control group) and underwent a 30-min period of SC ischemia by clamping the abdominal aorta between the left renal artery and the aortic bifurcation. 15 min before clamping, rabbits received either intravenous MB (10 mg/kg; group M) or normal saline (group C). The two groups were compared 24 h postoperatively both histologically and for neurological function, using a Tarlov score. Measurements to determine levels of malondialdehyde (MDA) and glutathione (GSH) in the SC tissue were also performed. Results: Neurological impairment and spinal tissue MDA levels were significantly lower in animals treated with MB (p < 0.001). In contrast, spinal GSH levels were significantly higher in group M (p < 0.001). Histological examination revealed that the integrity of the SC was better preserved in the MB group, whereas cords from the control group exhibited evidence of acute neuronal injury. Conclusions: The prophylactic use of MB reduces neurological injury and improves clinical outcomes in the rabbit SC I/R model. These effects are probably mediated by the drug's antioxidant properties. Copyright © 2006 S.

Recent research disclosed a peroxidase activity of citochrome c that could be correlated with electrostatic interactions with cardiolipin and consequent tertiary structure alterations. We study here citochrome c structural changes promoted by interactions with PC (1.0 mM)/PG (0.1 mM) vesicles by circular dichroism (CD) and alterations of the iron spin state by low temperature EPR. CD spectral studies revealed that despite alterations in the far (208 nm) and near (282 nm) UV, the vesicles unaffected the a-helix (37%), b- sheet (26%), random protein contents (37%), whereasthe Soret bands (405 and 416 nm) underwent significant collapse. Low temperature EPR studies in the presence of SIN -1, a peroxynitrite generator in aerated medium, and of tertbutyl hydroperoxide, both in the presence and absence of vesicles and of oxygen, showed reduction of the heme iron to iron-II by superoxide species and possibly re- oxidation of iron-II by peroxide generated free radicals. In conclusion, it seems that the vesicle lipids protect cytochrome c against oxidative damage and bleaching caused by peroxides. SUPPORT: FAPESP; CNPq; IFS, Milênio Redoxoma. Who loves ya.

Many patients on the drug report that >their urine turns blue, but Wischik said so far the drug appears safe. Work done in the 1960's sggested that methylene blue was toxic to nerve tissue. Other studies: 1: J Neurol Neurosurg Psychiatry. 1978 Apr;41(4):384-6. Spinal cord necrosis after intrathecal injection of methylene blue. Sharr MM, Weller RO, Brice JG. A 59 year old man had 6 ml of unbuffered methylene blue injected into the lumbar theca in an attempt to localise the source of cerebrospinal fluid rhinorrhoea. After injection of the dye he became shocked, and within the next few days he developed a mild paraparesis which subsequently progressed to a total paraplegia. The distribution of the spinal cord damage found at necropsy, eight and a half years after injection of the dye, is described and its relationship to the clinical picture discussed.

Letter: Neurological deficits resulting from intrathecal administration of methylene blue. Gross SW. PMID: 4408272 [PubMed - indexed for MEDLINE] 3: Anesthesiology. 1970 Sep;33(3):335-40.
