Abstract

Abstract Background This study was designed to evaluate the protective effects of a Rhamnus alaternus aqueous extract (RAAE) on aluminum chloride-induced hepatotoxicity in rats. A preliminary phytochemical study and antioxidant activity tests of the extract were performed. Methods A preliminary phytochemical study and antioxidant activity tests of the extract were performed. For the in vivo study, twenty-four male rats were divided into four groups. The control group (C); the RAAE group treated with 250 mg/kg b.w RAAE; the AlCl 3 group, which received 50 mg/kg b.w AlCl 3 ; and the AlCl 3 /RAAE group that was treated with AlCl 3 plus RAAE. Results The RAAE contains several phenolic compounds. This plant extract showed a high radical scavenging effect and high antioxidant activity. Administration of AlCl 3 resulted in a significant increase in the activities of aspartate aminotransferase and alanine aminotransferase (AST, ALT), alkaline phosphatase (ALP), and lactate dehydrogenase (LDH) and significant decreases in the plasma concentrations of total proteins and albumin. Moreover, AlCl 3 induced a hepatic pro-oxidant effect leading to an increase in malonaldehyde (MDA) and carbonyl protein contents, the depletion of the content of reduced glutathione (GSH) and a decrease in the antioxidant enzymatic activities of superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPx). However, RAAE supplementation with AlCl 3 treatment significantly decreased the levels of MDA and carbonyl proteins and markedly restored the activities of the antioxidant enzymes. These results are supported by the improvement in liver tissue restoration. Conclusions The Rhamnus alaternus aqueous extract was shown to have effective antioxidant activity owing to its phenolic compounds protecting against AlCl 3 -induced liver oxidative damage.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
