Evaluation of the Quality of Sleep, Endothelial Function, Cardiovascular Risk, Thyroid Function, a Function of Masticatory Muscles and Psycho-emotional State of Patients With Sleep Bruxism

Sleep apnea is a common and serious health problem in the Polish population. According to epidemiological data problem concerns about 7% of the adult population. The most common sleep disorder is obstructive sleep apnea (OSA). The consequence of episodes of airway obstruction and sleep fragmentation is an inefficient sleep, pathological daytime sleepiness, falling asleep involuntarily, awakening with feelings of shortness of breath or throttling. The direct consequences of sleep apnea are hypoxia, increased heart rate and increased blood pressure. Frequent complications of OSA are hypertension, stroke, cardiac arrhythmia, coronary artery disease and pulmonary hypertension. An additional problem in patients with sleep apnea is an increased incidence of bruxism. Bruxism is a common problem; reports of prevalence range from 8-31% in the general population. The most common symptoms of bruxism include: hypersensitive teeth, tooth wear, damage to dental restorations (e.g. crowns and fillings), damage to periodontal and oral mucosa, masticatory muscle pain and headaches. The etiology of bruxism is multifactorial and not fully understood. It can be caused by biologic, psychologic and exogenous factors. Arousals during the apnea episodes are considered to be a major cause of sleep bruxism in OSA patients. The relationship between OSA and sleep bruxism is still not clearly defined. Further research is needed to help explain the relationship between these two phenomena, which will enable further therapy in patients with coexisting OSA and sleep bruxism (SB).

Double Blind Placebo Control Opipramol-Baclofen Treatment for Addiction: Medical and Cognitive Effects

The aim of this study is examining the combination of two FDA approved drugs, Opipramol and baclofen, which may increase rehabilitation from psychoactive substances. Previous studies have indicated a connection of sigma-1 receptor to cocaine abuse and raised the possibility that these receptors as mediators of drug craving . However previous studies showed partial efficacy with no significant relapse in relapse rates. The same is true for the use of GABAb-1 receptor antagonist. Opipramol is a selective agonist for sigma-1 receptor. It is clinically used as an antidepressant and anxiolytic agent. Moreover, previous open and controlled trials indicated that the GABAb-1 antagonist baclofen partial efficacy in suppressing withdrawal symptoms in alcohol addicts and cocaine. Our studies in an animal model for addiction have shown a significant effect of the combine treatment of the indicated medications both in decreasing relapse and increase of -number of respondents.

Several receptor mediated pathways have been shown to modulate the murine head twitch response (HTR). However, the role of sigma receptors in the murine (±)-2,5-dimethoxy-4-iodoamphetamine (DOI)-induced HTR has not been previously investigated. We examined the ability of LS-1-137, a novel sigma-1 vs. sigma-2 receptor selective phenylacetamide, to modulate the DOI-induced HTR in DBA/2J mice. We also assessed the in vivo efficacy of reference sigma-1 receptor antagonists and agonists PRE-084 and PPCC. The effect of the sigma-2 receptor selective antagonist RHM-1-86 was also examined. Rotarod analysis was performed to monitor motor coordination after LS-1-137 administration. Radioligand binding techniques were used to determine the affinity of LS-1-137 at 5-HT2A and 5-HT2C receptors. LS-1-137 and the sigma-1 receptor antagonists haloperidol and BD 1047 were able to attenuate a DOI-induced HTR, indicating that LS-1-137 was acting in vivo as a sigma-1 receptor antagonist. LS-1-137 did not compromise rotarod performance within a dose range capable of attenuating the effects of DOI. Radioligand binding studies indicate that LS-1-137 exhibits low affinity binding at both 5-HT2A and 5-HT2C receptors. Based upon the results from these and our previous studies, LS-1-137 is a neuroprotective agent that attenuates the murine DOI-induced HTR independent of activity at 5-HT2 receptor subtypes, D2-like dopamine receptors, sigma-2 receptors and NMDA receptors. LS-1-137 appears to act as a sigma-1 receptor antagonist to inhibit the DOI-induced HTR. Therefore, the DOI-induced HTR can be used to assess the in vivo efficacy of sigma-1 receptor selective compounds.

Cocaine-induced convulsions: pharmacological antagonism at serotonergic, muscarinic and sigma receptors

Article

作者: M. C. Ritz ; Frank R. George

The concurrent influence of multiple neurotransmitter systems in mediating cocaine-induced convulsions is predicted by the results of previous receptor binding studies. The present results demonstrate that pharmacological manipulations of these predicted neurotransmitter systems alters the occurrence of cocaine-induced convulsions. The 5-HT reuptake inhibitor fluoxetine enhanced the occurrence and severity of convulsions produced by 100 mg/kg (-) cocaine, while the 5-HT2 receptor antagonists cinanserin, ketanserin and pirenperone antagonized cocaine-induced convulsions in a dose-dependent manner. Further, the M1 receptor antagonist pirenzepine antagonized cocaine-induced convulsions, but atropine did not. In addition, both the (+) and (-) stereoisomers of the sigma ligand SKF 10047 significantly attenuated cocaine-induced convulsions. (+)SKF 10047 was more potent than (-)SKF 10047 in this effect, suggesting a stereoselective effect at sigma receptor sites. In constrast, DA and NE neurotransmission do not appear to modulate the proconvulsant effects of cocaine in a specific, dose-dependent manner. Thus, of the CNS binding sites with which cocaine is known to interact, the results are consistent with the conclusion that 5-HT transporters and 5-HT2 receptor sites appear to be direct and primary sites related to cocaine-induced convulsions, while M1 and sigma binding sites appear to play important but secondary and modulatory roles in this response.

sigma receptor ligands represent a new class of potential antipsychotic drugs. This paper presents the structure-activity relationships leading to novel disubstituted piperidine sigma ligands, which have little or no affinity for dopamine D2 receptors. Selectivity for sigma sites over dopamine D2 or serotonin 5-HT2 receptors appears to be governed by the chemical nature of the piperidine nitrogen substituent, its distance from the basic nitrogen, and its orientation relative to the other piperidine substituent. Several of these compounds have good oral potency in some animal models used to evaluate potential antipsychotic drugs. The N-cyclopropylmethyl ketones and ethers (e.g. 6i (DuP 734), 6q, 18a, and 18n) have the best in vivo potency. Compounds 6i (DuP 734) and 6q did not cause catalepsy in the rat, even at very high doses. On the basis of the pharmacology profiles of these sigma ligands, we propose these compounds may be effective antipsychotic drugs, which do not induce extrapyramidal side effects or tardive dyskinesia.
