Abstract Title: 

Oridonin ameliorates lipopolysaccharide/D-galactosamine-induced acute liver injury in mice via inhibition of apoptosis.

Abstract: 

We investigated the protective effects exerted by oridonin, the main active constituent of the Chinese medicinal herb, against lipopolysaccharide (LPS)/D-galactosamine (D-Gal)-induced acute liver injury (ALI). An ALI model was induced in mice using LPS (40μg/0.5 ml) and D-Gal (5 mg/0.5 ml). The mice were randomly divided into the following five groups of six mice each: one control group (a), one ALI group (b), two oridonin treatment groups (c and d), and one oridonin control group (e). Oridonin (0.2 mg/0.5 ml) was administered once 1 h prior to theLPS/D-Gal challenge in group c and a total of three times over a period of four days, with the last dose given at 1 h before the LPS/D-Gal challenge, in group d. Pretreatment with oridonin improved the survival rate, alleviated histopathological abnormalities, and suppressed plasma aminotransferasesin the LPS/D-Gal-challenged mice. Importantly, oridonin attenuated LPS/D-Gal-induced apoptosis in hepatocytes by reducing pro-apoptotic signals (P
