The effect of succinic salt diethylethanolamine fumaric ester on the cognitive abilities male CBA mice and outbred rats was studied. It found that test substance at doses 10 75 mg/kg in “Extrapolation escape task” has a positive short-term long-term memory animals, contributing to preservation reproduction information received. In “T-maze” test, both superior, it had comparable with reference d...

Although maternal cigarette smoking during pregnancy is a well-documented risk factor for a variety of adverse pregnancy outcomes, how prenatal cigarette smoke exposure affects postnatal neurobehavioral/cognitive development remains poorly defined. In order to investigate the cause of an altered behavioral phenotype, mice developmentally exposed to a paradigm of 'active' maternal cigarette smok...

Post-training intracerebroventricular administration of procaine (20 micrograms/microliter) and dimethocaine (10 or 20 micrograms/microliter), local anesthetics of the ester class, prolonged the latency (s) in the retention test of male and female 3-month-old Swiss albino mice (25-35 g body weight; N = 140) in the elevated plus-maze (mean +/- SEM for 10 male mice: control = 41.2 +/- 8.1; procai...

Alzheimer's disease (AD) is a progressive neurodegenerative disorder and the AβPP/PS1 transgenic mouse model is a commonly used experimental model to mimic the pathological and cognitive impairments in AD. As a classic method to evaluate spatial learning and memory, the Morris water maze is widely applied to study the cognitive deficits in rodent AD models. However, the assay procedure is relat...

The elevated plus-maze (EPM) is a very common rodent test of anxiety. It is based on an approach-avoidance conflict between secure closed arms and aversive open arms. However, discrepancies remain on the interpretation of animals' behavior in this assay. The purpose of our study was to get a better understanding of the mouse behavior in the EPM. We applied a minute-by-minute analysis to compare...

Nitric oxide (NO) is an atypical neurotransmitter that causes changes in cognition. Nitric oxide synthase (NOS) and guanylate cyclase (GC) inhibitors have been shown to exert some effects on cognition in previous studies; however, the findings have been controversial. This study was aimed at understanding the effects of an NOS inhibitor, 7-nitroindazole (7-NI), and a guanylate cyclase inhibitor...

METHODS Timed-pregnant C57BL/6J mice were exposed to 2.4% nicotine in propylene glycol (PG) or 0% nicotine /PG once a day from gestational day 15 until delivery. After delivery, offspring and mothers were exposed to E-cigarette vapors for an additional 14 days from postnatal day 2 through 16. Following their last exposure serum cotinine levels were measured in female juvenile mice. Male mice un...

Over the past years, two breeding lines, derived originally from outbred Wistar rats, have been established that differ markedly and consistently in their anxiety-related behaviour in the elevated plus-maze. At the age of ten weeks, rats were tested once on the elevated plus-maze and the males and females displaying the most anxious and the least anxious behaviour were sib-mated to start a new ...
