Abstract

In the central nervous system, glutamate appears to be the principal excitatory amino acid neurotransmitter. Recent findings show that beta-lactam antibiotics, by stimulating glutamate transporter (GLT-1) expression, offer neuroprotection. The purpose of our study is to observe the effect of ceftriaxone, a beta-lactam antibiotic, on spatial memory in mice. Male Balb-c mice, weighing 20-25 g, were trained in Morris water maze (n=12 for each group) task. Animals were given 4 trials per day for 7 consecutive days to locate a hidden platform (acquisition phase). On the eighth day, the platform is removed and the animals were swum for one session of 60 s (retention phase). Learning and memory functions of the animals were evaluated based on their performances in these tests. Ceftriaxone was given for 9 days at different doses (50, 100, and 200 mg/kg, i.p.); additionally, its acute effect was evaluated in one group (200 mg/kg, i.p.). Our immunohistochemistry findings indicate that ceftriaxone increases GLT-1 expression in CA1, CA3 and DG regions of hippocampus, especially with the dose of 200 mg/kg. Evaluation of the acquisition parameters, such as time to reach platform, distance moved, and mean distance to platform indicates that chronic ceftriaxone has no effect on learning curves of the animals. When retention phase parameters (e.g. time to reach target quadrant, swim duration in target quadrant, and mean distance to platform area) are evaluated, it was found that both chronic and acute ceftriaxone did not affect memory at any dose used. In contrast to the contribution of GLT-1 expression to various central nervous system diseases, such as chronic pain, amyotrophic lateral sclerosis, Parkinson's disease and seizures, our findings suggest that ceftriaxone has no effect on spatial memory function in mice.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
