AIM: Prolonged exposure to stress mainly affects the cognitive functions of the brain by inducing neuronal damage mediated through oxidative stress. Acorus calamus (AC) has long been used in Indian folk medicine for various central nervous system (CNS) abnormalities. Hence the present study investigates the effect AC on learning and memory in rats. MATErIAL and METHods: Adult Wistar male rats w...
The chronic unpredictable mild stress model of depression has been widely used as an experimental tool to investigate human psychopathology. Our objective was to provide an update on the validity and reliability of the chronic unpredictable mild stress model, by analyzing the interrelationships among the indexes using stepwise discriminant analysis and Pearson correlation coefficient to examine...
CCK acts peripherally as a satiating peptide released during meals in response to lipid feeding and centrally functions in the modulation of feeding, exploratory, and memory activities. The present study determined metabolic parameters, food intake, anxiety-like behaviors, and cognitive function in mice lacking the CCK gene. We studied intestinal fat absorption, body composition, and food intak...
Aluminium is a potent neurotoxin and has been associated with Alzheimer's disease (AD) causality for decades. Prolonged aluminium exposure induces oxidative stress and increases amyloid beta levels in vivo. Current treatment modalities for AD provide only symptomatic relief thus necessitating the development of new drugs with fewer side effects. The aim of the study was to demonstrate the prote...
The present study was undertaken to investigate the effects of methanolic extract of Pterocarpus marsupium Roxb. on learning and memory in albino mice. Two doses of methanolic extract of P. marsupium (25 and 50 mg/kg p.o.) were administered for neurotoxicity test. The mice administered with 25 mg/kg of the extract could significantly maintain the equilibrium on the rotating rod. Elevated plus-m...
Diabetes mellitus is one of the most common causes of neuropathy. Although antioxidant and antidiabetic effects of the aqueous extract of purslane (Portulaca oleracea) (AEOP) have been demonstrated before by other researchers, we did not find any study that assessed the psychobiological effects of AEOP in diabetes induced animals. Thirty ovariectomized (OVX) female Wistar rats were randomly div...
Previous studies have demonstrated that benzo(a)pyrene (BaP) may disrupt the development of key biological systems, thus leaving children more vulnerable to functional impairments in adulthood. The current study was conducted to determine whether neurotoxic effects of postnatal BaP exposure on behavioral performance persist in juvenile and young adult stages. Therefore, neonate Sprague-Dawley p...
PURPOSE Seizures in the developing brain cause less macroscopic structural damage than do seizures in adulthood, but accumulating evidence shows that seizures early in life can be associated with persistent behavioral and cognitive impairments. We previously showed that long-term spatial memory in the eight-arm radial-arm maze was impaired in rats that experienced a single episode of kainic aci...
