Effect of intranasal and oral administration of levetiracetam on the temporal and spatial distributions of SV2A in the KA-induced rat model of SE.

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
To investigate the effectiveness of nasal delivery of levetiracetam (LEV) on the distributions of synaptic vesicle protein 2 isoform A (SV2A) in epileptic rats with injection of kainic acid (KA) into amygdala. A total of 138 rats were randomly divided into four groups, including the Sham surgery group, the epilepsy group (EP), and the LEV oral administration (LPO) and nasal delivery (LND) groups. The rat intra-amygdala KA model of epilepsy was constructed. Pathological changes of rat brain tissue after status epilepticus (SE) were detected using haematoxylin and eosin staining. Expression of SV2A in rat hippocampus after SE was evaluated using the western blotting analysis. Expression and distribution of SV2A in rat hippocampus after SE were detected based on immunofluorescence staining. The EP group showed evident cell loss and tissue necrosis in the CA3 area of hippocampus, whereas the tissue damage in both LPO and LND groups was significantly reduced. Western blotting analysis showed that the expressions of SV2A in the hippocampus of both EP and LND groups were significantly decreased 1 week after SE, increased to the similar levels of the Sham group in 2 weeks, and continuously increased 4 weeks after SE to the level significantly higher than that of the Sham group. Results of immunofluorescence revealed largely the same expression patterns of SV2A in the CA3 area of hippocampus as those in the entire hippocampus. Our study revealed the same antiepileptic and neuronal protective effects by the nasal and oral administrations of LEV, without changing the expression level of SV2A.
