Paneth-like cells disruption and intestinal dysbiosis in the development of enterocolitis in an iatrogenic rectosigmoid hypoganglionosis rat model.

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
Background: Hypoganglionosis resembles Hirschsprung disease (HSCR) which is characterized by severe constipation. Enterocolitis due to hypoganglionosis or Hirschsprung-associated enterocolitis (HAEC) is a life-threatening complication of both diseases. This study investigated the role of Paneth-like cells (PLCs) and gut microbiota in the development of enterocolitis in an iatrogenic rectosigmoid hypoganglionosis rat model. Methods: The rectosigmoid serosa of male Sprague-Dawley rats were exposed to 0.1% benzalkonium chloride (BAC). The rats were then sacrificed after 1, 3, 5, 8, and 12 weeks. A sham group was sacrificed on Week 12. With hematoxylin-eosin staining, the ganglionic cells were quantified, the degree of enterocolitis was analyzed, and the PLCs was identified. Intestinal barrier function was assessed for the anti-peripherin, occludin, and acetylcholinesterase (AChE)/butyrylcholinesterase (BChE) ratio. qRT-PCR was used as reference for the evaluation of antimicrobial peptide (AMP) of PLCs using cryptdins, secretory Phospholipase A Results: After 1 week of intervention, the ganglion cells were fewer in all sacrificial 0.1% BAC groups at varying times than those in the sham group. Occludin and peripherin were decreased, while the AChE/BChE ratio was increased. At Week 5 postintervention, the number of α-defensins-positive PLCs increased in the sigmoid colon tissues from BAC-treated rats. Conversely, PLCs-produced AMP decreased from Week 5 to Week 12. The sham group demonstrated increased Conclusion: Application with BAC influences the disruption of PLCs in Week 5 postintervention, and dysbiosis exacerbate the occurrence of enterocolitis. Further research on Paneth cells involvement in HAEC development is warranted.
