Neuroprotective Effects of Curcumin against Chronic Chlorpyrifos- Induced Oxidative Damage in Rat Brain Tissue.
Article in Current aging science, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled it.
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
backgroundChlorpyrifos (CPF) is an organophosphate pesticide that inhibits acetylcholinesterase (AChE) activity. Investigations have also focused on its neurotoxicity, which is independent of AChE inhibition. Here, we evaluated the effect of CPF on oxidative indices in the brain tissue and explored the protective effect of curcumin (Cur) against its toxicity.
methodsForty male Wistar rats were divided into five groups, each consisting of eight rats (n = 8) per group. Animals were administrated by oral gavage for 90 days with the following treatments: control (C), CPF, CPF + CUR 25 mg/kg, CPF + CUR50, and CPF + cur 100 received olive oil, CPF, CPF plus 25 mg/kg of CUR, CPF plus 50 mg/kg of CUR, and CPF plus 100 mg/kg of CUR, respectively. After anesthetization, animal brain tissues were obtained for assessment of oxidative stress indices.
resultsThe concentration of MDA significantly increased in the brains of the CPF group as compared to the control group (p < 0.01). Also, a significant decrease in MDA concentrations was observed in the brains of rats in the CPF + Cur 100 group compared to the CPF group (p < 0.05). A significant decrease was noted in the GSH concentration in the brains of the CPF group compared to the control group (p < 0.05). Treatment with Cur at 100 mg/kg exhibited a significant increase in GSH concentrations in the brains of the CPF-exposed group compared to the CPF group without Cur administration (p < 0.05). The concentration of NO exhibited a significant increase in the brains of the CPF group when compared to the control group (p < 0.05). Also, a significant decrease in NO concentration was observed in the brain tissue of the CPF + Cur 100 group compared to the CPF group (p < 0.05).
conclusionOur data establish that chronic exposure to CPF induced oxidative stress in brain tissue, which was reversed by CUR administration. Additional experimental and clinical investigations are needed to validate the efficacy of CUR as a potential antidote for CPF poisoning.
