Effect of Aloe vera on the expression of nerve factors, p75 and TrkA receptors in the hippocampus of diabetic rats

Int. j. morphol; 39 (2), 2021
SUMMARY: Diabetes mellitus can lead to structural disorders in the brain. One of the most common complications of diabetes, diabetic neuropathy is associated with central nervous system disorders. Aloe vera has anti-diabetic, antioxidant, and neuroprotective effects. This study was designed to evaluate t...

Effect of titanium dioxide nanoparticles on the stereological parameters of the dentate gyrus and the morphology of granular hippocampal neurons in mice

Int. j. morphol; 38 (6), 2020
SUMMARY: This study aims to investigate the Effects of Titanium dioxide nanoparticles (TiO2 NPs) on the stereological parameters in the dentate gyrus and the morphology of granular hippocampal neurons in adult mice. Adult male mice (n=20, weight average: 45 g) were randomly divided into four groups inclu...

Fenugreek seed extract alleviates hippocampal dendritic atrophy in streptozotocin induced diabetic rats

Int. j. morphol; 38 (6), 2020
SUMMARY: Herbal extracts used for treatment of diabetes has focused mostly on the hypoglycaemic and anti-oxidant property.There are no studies which focused on its effect on dendritic architecture of pyramidal neurons of hippocampus caused by diabetes. This study was taken up to explore the effect of adm...

Effects of Beta; 1-adrenoceptors in the Basolateral Amygdala on Spatial Memory, Passive Avoidance, Long-term Potentiation and Neuronal Arborization in the Hippocampal CA1 Region in Response to Unavoidable Stress

Abstract Norepinephrine in the basolateral amygdala (BLA) plays a pivotal role in mediating the effects of stress on memory functions in the hippocampus, however, the functional contribution of β1-adrenergic receptors on the BLA inputs to the CA1 region of hippocampus and memory function are not wel...

Neonatal exposure to citalopram increases pyramidal and granular cell density in dorsal hippocampus of male but not female adult rats: a quantitative Nissl study

Int. j. morphol; 37 (2), 2019
Antidepressants use during pregnancy was associated with an increased risk of autism spectrum disorders. Animal models based on early life alterations in serotonin availability replicate some of the anatomical and behavioral abnormalities observed in autistic individuals. In recent years there has been a...

Adenosine a1 receptor agonist protects against hippocampal neuronal injury after lithium chloride-pilocarpine-induced epilepsy

Rev. invest. clín; 71 (2), 2019
Abstract Background Adenosine A1 receptor (AA1R) is widely present in the central nervous system, exerting brain protective antiepileptic effects, mainly by binding corresponding G proteins. We evaluated the neuroprotective effects of AA1R on hippocampal neuronal injury after lithium chloride-pilocarpin...

Effects of repeated exposure to different concentrations of sevoflurane on the neonatal mouse hippocampus

Rev. bras. anestesiol; 69 (1), 2019
Abstract Background and objectives: Developing brain is more vulnerable to environmental risk than is the developed brain. We evaluated the effects of repeated exposure to different concentrations of sevoflurane on the neonatal mouse hippocampus using stereological methods. Methods: Eighteen neonatal m...

1-triacontanol cerotate isolated from Marsilea quadrifolia Linn. safeguards hippocampal CA3 neurons and augments special memory deficit in chronic epileptic rats

Int. j. morphol; 37 (1), 2019
SUMMARY: Currently many people with epilepsy do not have seizure control even with the best available medications. Moreover various antiepileptics have adverse cognitive impact with other side effect. Thus, need for new antiepileptic drugs still remains challenge. However, many of the natural components ...

Effects of huperzine A on hippocampal inflammatory response and neurotrophic factors in aged rats after anesthesia

Acta cir. bras; 34 (12), 2019
Abstract Purpose To investigate the effects of huperzine A (HupA) on hippocampal inflammatory response and neurotrophic factors in aged rats after anesthesia. Methods Thirty-six Sprague Dawley rats (20-22 months old) were randomly divided into control, isofluran, and isoflurane+HupA groups; 12 rats i...

Neuroprotective effects of an Nrf2 agonist on high glucose-induced damage in HT22 cells

Biol. Res; 52 (), 2019
BACKGROUND: Oxidative stress is the hallmark of diabetic encephalopathy, which may be caused by hyperglycaemic toxicity. We aimed to discover pharmacologic targets to restore redox homeostasis. We identified the transcription factor Nrf2 as such a target. METHODS: HT22 cells were cultured in 25 or 50 mM ...
