Immunostimulatory, anti-inflammatory, and immunomodulatory effects of Gum Arabic: regulation of cytokines and phagocytic function in rats.

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
Introduction: The role of natural dietary fibers in supporting immune function and systemic physiological responses is increasingly recognized. This study evaluated the effect of long-term oral administration of gum arabic (GA) on the immune function of rats. Method: Seventy-six adult male Wistar rats were assigned to five groups: controls, GA treated (5% or 10% in drinking water for 6 weeks), and GA combined with LPS or dexamethasone, alongside corresponding LPS and dexamethasone controls.Phagocytic, histological, and immune markers were estimated and evaluated statistically by using one-way ANOVA followed by Duncan's multiple range test. Results: GA treatment significantly increased serum complement-3 levels, lysozyme activity, immunoglobulin M (IgM), and nitric oxide (p < 0.05). GA also increased phagocytic index, neopterin, and intestinal mucosal eosinophil count, while spleen weight and mucosal mast cell count remained unchanged. GA mitigated the inhibitory effects of intramuscular dexamethasone on immune parameters and improved intravascular carbon clearance, and effectively attenuated the LPS induced increase in the pro-inflammatory cytokines (IL-1α, IL-4, IL-6, and TNF-α). Conclusion: These findings suggest that GA modulates selected immune parameters, enhances innate immune responses, and maintains systemic immune responsiveness under both normal and challenged conditions in rats.
