BACKGROUND: Valproic acid (VPA) is a first-line antiepileptic drug. It is used in the treatment of many different types of partial and generalized epileptic seizures. Though the clinical pharmacokinetics of VPA has been well defined, information about pharmacokinetics after overdoses is rare. The aim of this study was to try to build a population pharmacokinetic model that would describe the time course of VPA and its selected metabolites when the drug is ingested in an overdose situation...

BACKGROUND: Exposure to Mn results in a neurological syndrome known as manganism. METHODS: We examined how 4-week Mn exposure (20mg/kg MnCl2po, 5days/week) induces neurotoxic effects in rats. Oxidized-to-reduced glutathione ratio (GSSG/GSH), malondialdehyde (MDA), superoxide dismutase (SOD) activity, catalase (CAT) activity, vitamin E content and caspase-3 activity were measured in several rat brain structures. Further, we examined protective effects of the polyphenols: resveratrol (R) or quercetin (QCT) against Mn-induced neurotoxicity...

BACKGROUND: Role of brain renin angiotensin system (RAS) is well understood and various clinical studies have proposed neuroprotective effects of ARB's. It is also assumed that diabetic depression is associated with activation of brain RAS, HPA axis dysregulation and brain inflammatory events. Therefore, the present study was designed to investigate the antidepressant effect of low dose telmisartan (TMS) in diabetes induced depression (DID) in rats. METHODS: Diabetes was induced by injecting streptozotocin...

BACKGROUND: Quercetin is a well-known flavonoid, has pharmacokinetic interaction with ester drugs due to its capability of esterase inhibition in the gut and liver. However, the interaction between quercetin nanoparticles (NQC) and rivastigmine has not been reported. Hence, the present study was performed to evaluate the effect of quercetin alone and its nanoparticles on the pharmacokinetics of rivastigmine in rats. METHODS: NQC prepared by antisolvent precipitation method...

BACKGROUND: Diarrhea-predominant irritable bowel syndrome (IBS-D) is a functional disorder of the gastrointestinal (GI) tract. The major IBS-D symptoms include diarrhea, abdominal pain and discomfort. High density of opioid receptors (ORs) in the GI tract and their participation in the maintenance of GI homeostasis make ORs ligands an attractive option for developing new anti-IBS-D treatments. The aim of this study was to characterize the effect of methyl-orvinol on the GI motility and secretion and in mouse models mimicking symptoms of IBS-D...

BACKGROUND: Repeated stress paradigms have been shown to cause devastating alterations on memory functions. Stress is linked with inflammation. Psychological and certain physical stressors could lead to neuroinflammation. Inflammatory process may occur by release of mediators and stimulate the production of prostaglandins through cyclooxygenase (COX). Treatment with COX inhibitors, which restrain prostaglandin production, has enhanced memory in a number of neuroinflammatory states showing a potential function for raised prostaglandins in these memory shortfalls...

BACKGROUND: In the past decade it has been shown that tolerance develops to the antinociceptive effect of repeated systemic administration of commonly used non-steroidal anti-inflammatory drugs (NSAIDs) in acute pain models using rats. This is similar to the tolerance observed with opioid-induced analgesia. In the present study, we investigated the development of tolerance to the analgesic effects of NSAIDs diclofenac, ketorolac and xefocam in a chronic inflammatory pain model, the formalin test...

BACKGROUND: Adolescence is characterized by major neurobiological changes, and the effects of some psychoactive drugs seem to differ between adolescents and adults. Bupropion, an antidepressant that is also used to treat nicotine addiction, induces behavioral actions in both adolescent and adult rodents. However, the effects of this drug on spatial ability have not been compared in animals at different stages of their development. The present study was conducted to assess the effects of bupropion on spatial learning and memory in adolescent and adult mice...

BACKGROUND: Many disease entities, including coronary artery disease (CAD), demonstrate abnormalities in the activity of cholinesterases. As CAD is characterized by an increase in cholesterol level, patients with this disease are treated with lipid-lowering drugs. The present study attempts to determine how statin or combined statin and ezetimibe therapy influences cholinesterase activity. METHODS: Plasma and erythrocytes were isolated from the peripheral blood of CAD patients (n=61) and healthy subjects (n=63)...

Tanveer Singh, Rajesh Kumar Goel
BACKGROUND: Elevated nitric oxide (NO) levels in the brain have been apparently associated with depression in kindled animals. Owing to the major role of neuronal nitric oxide synthase (nNOS) in brain and ineffectiveness of antiepileptic drugs (AEDs) in restoring nitrosative stress, the present study was envisaged to evaluate the adjuvant nNOS inhibitor, 7-nitroindazole (7-NI) with valproic acid for combined treatment of epilepsy and associated depression. METHODS: Pentylenetetrazole kindled animals associated with depression were treated with vehicle, valproate (300mg/kg/day ip), valproate with 7-NI (10mg/kg; 20mg/kg; 40mg/kg)/day ip and 7-NI (40mg/kg/day ip) for 15days...

Tsugunobu Andoh, Akira Shinohara, Yasushi Kuraishi
BACKGROUND: Our previous study showed that the μ-opioid receptor agonist fentanyl citrate inhibits endothelin-1-and bradykinin-mediated pain responses in mice orthotopically inoculated with melanoma cells. We also demonstrated that bradykinin induces endothelin-1 secretion in melanoma cells. However, the analgesic mechanisms of fentanyl citrate remain unclear. Thus, the present study was conducted to determine whether fentanyl citrate affects bradykinin-induced endothelin-1 secretion in B16-BL6 melanoma cells...

REVIEW
Marek Cieślak, Andrzej Wojtczak, Michał Komoszyński
Adenine nucleotides and adenosine are signaling molecules that activate purinergic receptors P1 and P2. Activation of A1 adenosine receptors has an anticonvulsant action, whereas activation of A2A receptors might initiate seizures. Therefore, a significant limitation to the use of A1 receptor agonists as drugs in the CNS might be their peripheral side effects. The anti-epileptic activity of adenosine is related to its increased concentration outside the cell. This increase might result from the inhibition of the equilibrative nucleoside transporters (ENTs)...

BACKGROUND: Cholesterol-dependent and independent mechanisms were proposed to explain anti-atherosclerotic action of statins in humans. However, their effects in murine models of atherosclerosis have not been consistently demonstrated. Here, we studied the effects of pravastatin on atherosclerosis in ApoE/LDLR(-/-) mice fed a control and atherogenic diet. METHODS: ApoE/LDLR(-/-) mice were fed a control (CHOW) or an atherogenic (Low Carbohydrate High Protein, LCHP) diet...
