Outcome of resveratrol and resveratrol with donepezil combination on the β-amyloid plaques and neurofibrillary tangles in Alzheimer's disease.

The goal of this research was to study the effect of different doses of resveratrol (RS) and RS with donepezil (DPZ) on the deposition of amyloid beta (Aβ) and neurofibrillary tangles (NFTs) in colchicine-induced Alzheimer's disease (AD) brain. The study included three months old male Albino  rats and consisted of six animal groups: AD model (group 1), treatment groups, RS 10 mg/kg body weight (group 2), RS 20 mg/kg body weight (group 3), RS 10 mg/kg body weight along with DPZ 1 mg/kg body weight (group 6), prophylaxis groups, RS 10 mg/kg body weight (group 4) and RS 20 mg/kg body weight (group 5). In the treatment groups, RS was given for 7 consecutive days from the day of induction of AD, and in the prophylaxis groups, we started RS 7 days even before the induction of AD and continued for seven days after the induction.

Effect of resveratrol and combination of resveratrol and donepezil on the expression of microglial cells and astrocytes in albino rats of colchicine-induced Alzheimer's disease.

Aim: The goal was to evaluate the effect of resveratrol (RS) and combination therapy of RS and donepezil (DPZ), on the numerical expression of microglial cells and astrocytes, in the frontal cortex, regions of the hippocampus in colchicine-induced Alzheimer's disease (AD) model.

Methods: The study involved male albino rats of three months, age and consisted of 6 groups, with six animals each. The immunohistochemical staining with mouse monoclonal anti-human CD 68 and mouse monoclonal anti-GFAP was performed to assess the number of microglial cells and astrocytes, respectively.

Hippocampus and its involvement in Alzheimer's disease: a review.

Hippocampus is the significant component of the limbic lobe, which is further subdivided into the dentate gyrus and parts of Cornu Ammonis. It is the crucial region for learning and memory; its sub-regions aid in the generation of episodic memory. However, the hippocampus is one of the brain areas affected by Alzheimer's (AD).

Neuroprotective effects of resveratrol in Alzheimer's disease.

Alzheimer's disease (AD) is a neurodegenerative disorder, which is commonly seen in older individuals. This is characterized by cognitive dysfunction, which leads to dementia. Pharmacological treatments for AD are mainly targeted on its symptoms like memory loss and cognitive impairment.

Effect of Atorvastatin on Serum Para-Oxonase-1 and C-Reactive Protein in Wistar Rats.

Statins have been widely used in the treatment of hypercholesterolemia and atherosclerotic disease. Atherosclerosis is an ongoing inflammatory response which is involved in mediating all stages of this multifactorial disease. The present study focuses on the long term effect of atorvastatin on the anti-atherogenic and anti-inflammatory properties with reference to para-oxonase and C-reactive protein levels in rats.

Unique temperature patterns in 24-h continuous tympanic temperature in tuberculosis.

Body temperature monitoring in most healthcare institutions is limited to checking the presence or absence of fever. Our present study evaluated the 24h continuous tympanic temperature pattern in patients with fever in order to detect typical patterns seen in tuberculosis (TB). This observational study was conducted on 81 undifferentiated fever patients whose recordings were stored using the TherCom device.

Improvement in Cognitive Parameters Among Offsprings Born to Alcohol Fed Female Wistar Rats Following Long Term Treatment with Centella Asiatica.

Prenatal ethanol exposure causes cognitive impairments in rats. This study was designed to evaluate the effect of Centella Asiatica (CeA) in offspring of alcoholic rats. Pregnant rats in alcoholic group were orally fed with 30% alcohol at a dose of 5 g/kg body weight during their gestation period.

Effect of Orexin A antagonist (SB-334867) infusion into the nucleus accumbens on consummatory behavior and alcohol preference in Wistar rats.

Objective: Nucleus accumbens (NAcc) has a role in addiction and ingestive behavior. In order to assess orexinergic system involved in this, we infused Orexin A antagonist and assessed the effect on food intake fluid intake and alcohol preference in Wistar rats.

Materials And Methods: Inbred Wistar rats (n = 54) were divided into control and experimental groups (low dose and high dose).

Involvement of Neuropeptide Orexin B in Basolateral Amygdala Mediated Consummatory Behaviour in Male Wistar Albino Rats.

Unlabelled: The basolateral amygdala has been implicated in the regulation of food intake besides the hypothalamic centres. In the present study, we hypothesized that the Orexin B, a polypeptide identified in the lateral hypothalamic region, may be involved in the modification of the functions the of amygdaloid centres. We therefore studied the effect of infusion of Orexin B and its antagonist (TCS-OX2-29) into Basolateral amygdala to study the feeding behaviour.

Beneficial effect of Omega-3 polyunsaturated fatty acids on neurosensorial impairments and oxidative status in Streptozotocin induced diabetic rats.

Objectives: The present study evaluated the beneficial effects of omega 3 PUFA present in fish oil on neurosensorial impairments, namely learning, memory and anxiety in Streptozotocin (STZ) induced diabetic rats. The brain homogenate was analysed for oxidative status following Omega 3 PUFA treatment.

Methods: Male, Wistar rats of 2-3 months old were divided into non diabetic controls, diabetic control, & fish oil treated diabetic rats (n = 6).

Effect of Orexin-A infusion in to the Nucleus Accumbens on consummatory behaviour and alcohol preference in male Wistar rats.

Background: Effect of administration of Orexin-A into nucleus accumbens (NAcc) in relation to the regulation of feeding behavior and alcohol consumption at specific time intervals is relatively unknown.

Materials And Methods: In this study, Male Wistar albino rats (n = 54) weighing about 250 ± 10 grams were implanted bilaterally with guide cannula (22 gauze) to target NAcc by stereotaxic surgery. Saline (0.
