Anti-inflammatory activity of novel derivatives of pyrazolo [3,4d] pyridazine against digestive system inflammation.
Article in Naunyn-Schmiedeberg's archives of pharmacology, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It has been retracted, and should not be counted. Cited by 1 paper.
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
The digestive system is exposed to severe inflammation as a result of taking some medications that have gastrointestinal side effects. Sixty Swiss-albino male mice were randomly distributed into six groups to treat inflammations of the colon, stomach, and small intestine caused by taking high doses of diclofenac (D), with two novel synthesized compounds, pyrazolo [3,4 d] pyridazine derivatives (Co1 and Co2). Myeloperoxidase enzyme activity was determined in the colon and small intestinal tissues. Serum contents of TNF-α, IL-22, IgG, and IgM were determined by ELISA. Histopathological examinations of the colon, small intestinal, and stomach tissues were microscopically analyzed. TNF-α, IL-22, and TNFSF11 gene expression were measured in the colon, intestinal, and spleen using qRT-PCR. Diclofenac caused surface columnar epithelial cell loss, focal necrosis of the gastric mucosa, inflammatory cell infiltration, and congested blood vessels in the stomach, colon, and small intestinal tissues. Co1 component was found to be better than Co2 component in reducing the focal necrosis of gastric mucosa and improving the histological structures of the stomach, colon, and small intestinal tissues. After 14 days, the activity of the myeloperoxidase enzyme was increased in group D and decreased in groups DCo1, DCo2, Co1, and Co2. Serum concentrations of TNF-α and IgG were increased, while IL-22 and IGM were reduced in the D, DCo1, and DCo2 groups compared with the Co1 and control groups. TNF-α gene was upregulated in the D group and downregulated in the Co1 group, while the IL-22 gene was downregulated in the D group and upregulated in the Co1 group compared with the control group. The CO1 component may be useful in reducing digestive system inflammation.
