1 · What the graph read from it

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.

2 · The registry

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

Previous study indicated that Ulinastatin (UTI) increased glutamine uptake by upregulation of glutamate transporters in astrocytes. These glutamate transporters have important role to improve cognitive function in hippocampus. In this study, we wanted to demonstrate whether UTI could improve learning and memory by using zebrafish behavior model and bio-markers. Zebrafish were 6-8 months of age and were 2.5-3.5 cm long. They were divided into four groups by control, 1X PBS-injected control, UTI 10,000, and 50,000 injected group. All PBS and UTI injected zebrafish were anesthetized by Tricainemethanesulphonate. We measured total time, distance moved, and frequency in each compartment of T-maze. We also measured the expression levels of glutamate transporter levels and cognitive bio-markers such as c-fos, c-jun, BDNF. UTI affected the learning and memory in zebrafish in a dose-dependent manner. In 50,000 unit/kg UTI-treated zebrafish, there were increases of time, distance, and frequency in target compartment. In 50,000 unit/kg UTI-treated zebrafish, there was an increase of time in target compartment. There was no difference among control, PBS-injected, and UTI 10,000 unit/kg-treated groups. EAAT4 glutamate transporter, c-fos and BDNF were significantly increased in 50,000 unit/kg UTI-treated group. UTI-enhanced learning and memory in zebrafish. The expressions of EAAT4 glutamate transporter, c- fos and BDNF in zebrafish were highly correlated may play a role.
