Cholecystokinin-8 protects central cholinergic neurons against fimbria-fornix lesion through the up-regulation of nerve growth factor synthesis.

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 this study, we demonstrate that cholecystokinin-8 (CCK-8) induces an increase in both nerve growth factor (NGF) protein and NGF mRNA in mouse cortex and hippocampus when i.p. injected at physiological doses. By using fimbria-fornix-lesioned mice, we have also demonstrated that repeated CCK-8 i.p. injections result in recovery of lesion-induced NGF deficit in septum and restore the baseline NGF levels in hippocampus and cortex. Parallel to the effects on NGF, CCK-8 increases choline acetyltransferase (Chat) activity in forebrain when injected in unlesioned mice and counteract the septo-hippocampal Chat alterations in fimbria-fornix-lesioned mice. To assess the NGF involvement in the mechanism by which CCK-8 induces brain Chat, NGF antibody was administrated intracerebrally to saline- and CCK-8-injected mice. We observe that pretreatment with NGF antibody causes a marked reduction of NGF and Chat activity in septum and hippocampus of both saline- and CCK-8-injected mice. This evidence indicates that the CCK-8 effects on cholinergic cells are mediated through the synthesis and release of NGF. Taken together, our results suggest that peripheral administration of CCK-8 may represent a potential experimental model for investigating the effects of endogenous NGF up-regulation on diseases associated with altered brain cholinergic functions.
