- W4212934155 abstract "Acroptilon repens (L.) DC, commonly known as Rhaponticum repens, is a popular traditional phytomedicine. The current study was conducted to evaluate the acute and subchronic toxicity of the hydroalcoholic extract of this herb with regard to its terpenoid contents in a BALB/c mice model and to investigate the toxicity of this medicinal herb. Identification of extract components of the plant was done using gas chromatography (GC)-mass spectrometry. In order to establish the acute toxicity model, a single dose of 2000 mg/kg of the extract was given orally to male mice and in the subchronic toxicity study, the extract was consecutively administered at doses 250, 500, and 1000 mg/kg for 28 days. After 28 and 42 days, signs of toxicity and mortality were observed. Organ weight changes and the toxicity-associated parameters such as biochemical indicators, oxidative stress indices, mitochondrial parameters, apoptosis-associated gene expression levels, and pro-inflammatory cytokines were evaluated along with the histopathological examination. GC analysis showed that the terpenoids are the major components of the extract. The LD50 value (2 g/kg) was obtained in the acute toxicity assay; the subchronic administration caused a significant elevation in the serum biomarkers as well as in the levels of lipid peroxidation, protein carbonyl, and ROS. Besides, significant reductions in the superoxide dismutase and catalase activities were observed. This toxic effect was further confirmed by histological studies, cytokine assay, and gene expression assays. Following the treatment discontinuation, the abnormalities in the values of biochemical parameters and histopathological changes returned to normal. These findings demonstrate that the subchronic administration of the hydroalcoholic extract of A. repens can reversibly cause toxicity by inducing oxidative stress and mitochondrial dysfunction." @default.
