Methamphetamine (METH) is a widely abused illegal psychostimulant, which is confirmed to be neurotoxic and of great damage to human. Studies on the role of brain-derived neurotrophic factor (BDNF) in human METH addicts are limited and inconsistent. The purposes of this study are to compare the serum BDNF levels between METH addicts and healthy controls during early withdrawal, and explore the c...
Amphetamineanalogs have emerged as popular recreational drugs of abuse. The number of reports of these substances producing severe acute toxicity and death is increasing. In 'Ecstasy' -associated deaths, focal necrosis in the liver and individual myocytic necrosis has been reported. Furthermore, serotonergic and dopaminergic neuronal cell damage has been observed in experimental amphetamine int...
The present study was performed to evaluate the neurotoxicity of sodium nitrite (NaNO2) and nisin in cerebral cortex and hippocampus. A total of 27 adult female rats were divided into three groups, control group, sodium nitrite and nisin treated groups with 9 rats per each. The rats of groups 2 and 3 were given orally 30 mg/kg body weight and 50 mg/kg b.w daily of NaNO2 and nisin respectively f...
Elevated homocysteine (Hcy) levels have been reported to be involved in neurotoxicity after ischemic stroke. However, the underlying mechanisms remain incompletely understood to date. In the current study, we hypothesized that neuronal autophagy activation may be involved in the toxic effect of Hcy on cortical neurons following cerebral ischemia. Brain cell injury was determined by hematoxylin-...
Pregnenolone (PRG), a major neurosteroid, suppressed carbachol-induced salivary secretion in perfused submandibular gland in rats. These effects were enhanced and depressed by agonistic muscimol (MUS) and antagonistic bicuculline to the γ-aminobutyric acid A receptor (GABA(A)-R), respectively. In contrast, PRG-sulfate, a sulfate-conjugated PRG metabolite, antagonized the suppressive effects of ...
Bv8/Prokineticin 2 (PROK2) is a bioactive peptide initially discovered as a regulator of gastrointestinal motility. Among multiple biological roles demonstrated for PROK2, it was recently established that PROK2 is an insult-inducible endangering mediator for cerebral damage. Aim of the present study was to evaluate the PROK2 and its receptors' potential involvement in amyloid beta (Aβ) neurotox...
