OBJECTIVES Intracerebral injection of bone marrow stromal cells (BMSCs) is being investigated as a therapeutic tool to prevent Alzheimer's disease (AD). Our aim was to investigate the effects of BMSCs by intrathecal injection in AD rat model. MATERIALS AND METHODS BMSCs were obtained from the bone marrow of Wistar rat and transplanted into AD rat model via intrathecal injection. The rat model...

We have shown that buspirone, a partial agonist of 5-hydroxytryptamine 1A (5-HT1A) receptors, improves motor dysfunctions induced by 6-hydroxydopamine (6-OHDA) and haloperidol in rats. The present work extends these findings by investigating the role of 5-HT1A receptors on catalepsy-like immobilization in rats, a model of Parkinson’s disease. Catalepsy was induced by unilateral infusion of 6-OH...

Introduction: Alzheimer’s disease is a progressive neurodegenerative disorder, characterized by impairment of memory and changes in behavior and personality. Recent evidence suggests that mitochondrial channels play important roles in memory disorders. Accordingly, the biophysical properties of a single potassium channel were investigated in the brain mitochondrial inner membrane of rat with...

An immunofluorescence study using unfixed cryostat sections of rat pituitary glands was carried out on sera from 34 patients with Hashimoto's thyroiditis, 28 patients with Graves' disease, 10 patients with thyroid adenoma and 50 healthy subjects. After absorption of sera with rat liver tissues, 19 of 34 patients retained reactivity to anterior pituitary cell antibodies (PCA, 55.8%). On the othe...

by late 18th or early 19th century, albino rats became the most commonly used experimental animals in numerous biomedical researches, as they have been recognized as the preeminent model mammalian system. but, the precise correlation between age of laboratory rats and human is still a subject of debate. a number of studies have tried to detect these correlations in various ways. but, have not s...

The rat is the most extensively studied model organism and is broadly used in biomedical research. Current rat disease models are selected from existing strains and their number is thereby limited by the degree of naturally occurring variation or spontaneous mutations. We have used ENU mutagenesis to increase genetic variation in laboratory rats and identified a recessive mutant, named tornado,...

Huntington’s disease is an autosomal-dominant, progressive neurodegenerative disorder with chorea, incoordination, cognitive decline, and behavioral difficulties, whereas bioflavonoids have the potential to promote anxiety depression. The aim of this study was investigate summarize synergistic effect silymarin, quercetin, hesperidin on depression in 3-nitropropionic acid (3-NP)-induced rat mode...
