Objectives: Crocin and safranal, the major constituents of saffron, exert neuroprotective effects. In the present study, we investigated the effects of crocin and safranal  (alone or in combination with insulin) on peripheral neuropathy in diabetic rats. Materials and Methods: Diabetes was induced by intraperitoneal (i.p.) injection of 60 mg/kg of streptozotocin (STZ) and confirmed by blood glu...

A bidirectional route of communication between the gastrointestinal tract and the central nervous system, termed the "gut-brain axis," is becoming increasingly relevant to treatment of cerebral damage. Panax Notoginsenoside extract (PNE) is popular for prevention and treatment of cardio-cerebrovascular ischemic diseases although plasma and cerebral exposure levels are extremely low. To date, th...

BACKGROUND AND PURPOSE Accumulation of iron after intracerebral hemorrhage causes free radical formation and oxidative damage resulting in liquefaction. The aim of this study was the investigation of molecular mechanisms underlying estrogen-mediated neuroprotective effect against iron-induced brain injury in vivo. METHODS Age-matched male and female Sprague-Dawley rats were stereotaxically in...

BACKGROUND Estrogen, a class of female sex steroids, is neuroprotective. Estrogen is synthesized in specific areas of the brain. There is a possibility that the de novo synthesized estrogen exerts protective effect in brain, although direct evidence for the neuroprotective function of brain-synthesized estrogen has not been clearly demonstrated. Methylmercury (MeHg) is a neurotoxin that induces...

The aim of the present study is to evaluate the neuroprotective effect of two antiglaucomatous substances, regardless of their hypotensive effect in the eye. Brimonidine, which does not reduce IOP when administered intraperitoneally, and latanoprost, which has a renowned hypotensive effect topically. We examined rat retinal ganglion cell (RGC) survival and size distribution in experimental glau...

Objective(s): Erythropoietin (EPO), is a 34KDa glycoprotein hormone, which belongs to type 1 cytokine superfamily. EPO involves in erythrocyte maturation through inhibition of apoptosis in erythroid cells. Besides its main function, protective effects of EPO in heart and brain tissues have been reported. EPO has a critical role in development, growth, and homeostasis of brain. Furthermore EPO h...

background and objectives:traditional medicine is an important approach to achieve new therapeutic strategies in basic and clinical pharmacology. allium hirtifolium boiss. and astragalus hamosus l. have been mentioned in iranian traditional medicine references for a kind of dementia with features and symptoms similar to those of alzheimer's disease (ad). in the present study, the neuroprot...

Scutellaria baicalensis Georgi (SB) is the medicinal plants mainly used in traditional Chinese medicine. It has been used for the treatment of various chronic inflammatory syndromes including respiratory disease, fever and gastric ulcer in traditional Eastern medicine and its major components; baicalin, baicalein and wogonin; were reported to have various biological effects. The aim of this stu...

Korean red ginseng (KRG) possesses neuroprotective activity. However, the potential neuroprotective value of KRG for the striatal toxicity is largely unknown. We investigated whether KRG extract (KRGE) could have a neuroprotective effect in a 3-nitropropionic acid- (3-NP) induced (i.p.) Huntington's disease (HD) model. KRGE (50, 100, and 250 mg/kg/day, p.o.) was administrated 10 days before 3-N...

PURPOSE To evaluate whether the postoperative, antiepileptic drug (AED) regimen influences seizure recurrence after anterior temporal lobectomy when considering the putative mechanism of action and possible neuroprotective effects. METHODS This was a retrospective study. Patients who had an anterior temporal lobectomy for refractory epilepsy, whose preoperative MRI indicated mesial temporal s...
