A Single Administration of Riluzole Applied Acutely After Spinal Cord Injury Attenuates Pro-inflammatory Activity and Improves Long-Term Functional Recovery in Rats.
Article in Journal of molecular neuroscience : MN, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
After spinal cord injury (SCI), emergency treatment intervention can minimize tissue damage, which is closely related to the recovery of long-term function. Here, we examined whether the administration of a single dose of riluzole (6 mg/kg) immediately after SCI was a critical window for the drug to exert its regulatory effect and limit long-term neurological deficits. The animals were sacrificed 1 day after administration for investigation of neuronal survival and a potential neuroinflammatory response, and sacrificed in the 6th week for assessment of neurological function. Riluzole applied in a single dose immediately post-SCI decreased the mRNA level of interleukin-1β at 6 h, reduced the destruction of neurons, and reduced the activation of microglia/macrophage M1 expression at day 1 post-SCI. Additionally, riluzole-treated rats showed higher expressions of interleukin-33 and its receptor ST2 in microglia/macrophages of the spinal cord than vehicle-treated rats, suggesting that this signaling pathway might be involved in microglia/macrophage-mediated inflammation. At 6 weeks, riluzole-treated rats exhibited higher motor function scores than vehicle-treated controls. In addition, riluzole-treated rats exhibited higher expression of GAP43 protein and shorter N1 peak latency and larger N1-P1 amplitude in motor-evoked potentials, compared to vehicle-treated rats. Together, these data suggested that early application of riluzole after SCI could be crucial for long-term functional recovery, so it may represent a promising therapeutic candidate within the critical therapeutic window for acute SCI.
