[Effects of ellagic acid on inflammation and oxidative stress induced by AKT gene transfection in mice with fatty liver disease].

To study the effects of ellagic acid(EA)on inflammation and oxidative stress in mice with fatty liver disease induced by AKT gene transfection,the 20 female FVB mice were randomly divided into normal control group,model group and ellagic acid administration group(150,300 mg·kg~(-1)·d~(-1))(n=5).EA experimental groups and model group were using a high pressure into the tail vein transfection plasmid AKT.The next day,EA was started to administered continuously for 5 weeks after the AKT gene transfection,while the model group and the normal control group were given the same amount of saline.

[Research progress of ellagitannin intestinal metabolite urolithins].

Ellagitannins is a kind of phenolic compounds with many biological activities. Recent studies have found that the effective ingredients of these compounds have close relationship with their colon-derived bacteria metabolites, that is urolithins. The objective of this study was to review the structure characteristics, types and distribution of urolithins, improvement in diseases related to prostate, breast and colon, as well as anti-cancer, anti-oxidation, anti-inflammation and other biological activities.
