bile duct ligation (bdl) is shown to induce cholestasis-related liver function impairments as well as consequent cognitive dysfunctions (i.e. impaired learning and memory formation). this study investigates the effects of cholestasis (14, 21 and 28 days post bile duct ligation) on spatial and non-spatial novelty detection, using a non-associative task. male mice weighing 30-35 g were used. chol...

background and objective: tamoxifen is one of the selective estrogen receptor modulators that exerts estrogen / anti-estrogen effects in various tissues. this study was done to evaluate the effect of chronic administration of tamoxifen on spatial memory and passive avoidance task in adult male wistar rats. methods: in this experimental study, 48 adult male wistar rats were randomly divided into...

objective(s): there is controversial evidence about the effect of methamphetamine (meth) on spatial memory. we tested the time- dependent effects of meth on spatial short-term (working) and long-term (reference) memory in meth –sensitized and withdrawn rats in the morris water maze. materials and methods: rats were sensitized to meth (2 mg/kg, daily/5 days, sc). rats were trained in water maze ...

introduction: exposure to 3, 4- methylenedioxymethamphetamine (mdma) could lead to serotonergic system toxicity in the brain. this system is responsible for learning and memory functions. studies show that mdma causes memory impairment dose-dependently and acutely. the present study was designed to evaluate the chronic and acute effects of mdmd on spatial memory and acquisition of passive avoid...

background: multiple sclerosis (ms) is a disease of the immune system that creates damage of learning and memory in that. using probiotic supplements is recommended for preventing ms disease and improving memory. this study aimed to investigate the effect of lactobacillus plantarum (lp) and bifidobacterium b94 (bb94), on acquisition phase of spatial memory in the local demyelination of rats` hi...

introduction: alzheimer disease is a progressive and irreversible neuropsychiatric disorder. melissa officinalis improves anxiety and clinical dementia symptoms caused by ad therefore, the purpose of the present study was to evaluate the effect of mellisa extract on spatial memory deficit induced by stz in mwm examination of male wistar rats. methods: in the present study, 112 male wistar rats ...

the aim of the present study was to evaluate the effect of melatonin as an antioxidant on spatial navigation memory in male diabetic rats. thirty-two male white wistar rats weighing 200 ± 20 g were divided into four groups, randomly: control, melatonin, diabetic and melatonin-treated diabetic. experimental diabetes was induced by intraperitoneal injection of 50 mg kg-1 streptozotocin. melatonin...
