Transient cerebral ischemia induces active astrocytosis without distinct neuronal death in the gerbil main olfactory bulb: a long-term analysis.

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
In the present study, we examined ischemia-induced neuronal and glial changes in the gerbil MOB at various time points during 60 days after 5 min of transient cerebral ischemia. The number of neuronal neuclei-immunoreactive neurons was not changed after ischemia/reperfusion (I/R). Myelin basic protein immunoreaction was well preserved after I/R. Five days after I/R, reactive form of GFAP-immunoreactive astrocytes began to increase in the external plexiform layer and granule cell layer: These reactive astrocytes peaked 10 days after I/R, thereafter, they decreased with time after I/R. Iba-1-immunoreactive microglia were ubiquitously distributed in all layers of the MOB. After I/R, significant changes in their morphology and immunoreactivity were not detected. The results of western blot analyses for GFAP, Iba-1 and MBP were similar to the immunohistochemical data. In addition, 8-hydroxy-2'-deoxyguanosine (a marker for DNA damage) immunoreactivity and SOD1, an antioxidant, protein levels were not changed in the ischemic MOB. These results indicate that neurons in the MOB are resistant to ischemic insult, showing that astrocytes are activated late in the ischemic MOB.
