title: Scutellaria baicalensis Georgi extract protects against alcohol‑induced acute liver injury in mice and affects the mechanism of ER stress.
abstract: The aims of the present study were to examine the hepatoprotective effect of Scutellaria baicalensis Georgi extract (Scutellariae Radix extract; SRE) against acute alcohol‑induced liver injury in mice, and investigate the mechanism of endoplasmic reticulum (ER) stress. High performance liquid chromatography was used for the phytochemical analysis of SRE. Animals were administered orally with 50% alcohol (12 ml/kg) 4 h following administration of doses of SRE every day for 14 days, with the exception of normal control group. The protective effect was investigated by measuring the levels of aspartate transaminase (AST), alanine transferase (ALT) and triglyceride (TG) in the serum, and the levels of glutathione (GSH) and malondialdehyde (MDA) in liver tissues. The levels of glucose‑related protein 78 (GRP78) were detected using immunohistochemical localization and an enzyme‑linked immunosorbent assay. Hepatocyte apoptosis was assessed using terminal‑deoxynucleoitidyl transferase mediated nick end labeling. The SRE contained 31.2% baicalin. Pretreatment with SRE had a marked protective effect by reversing the levels of biochemical markers and levels of GRP78 in a dose‑dependent manner. The results of the present study demonstrated that pretreatment with SRE exerted a marked hepatoprotective effect by downregulating the expression of GRP78, which is a marker of ER stress.
