ABSTRACT

Objective:

To observe the effect of long-term administration of emodin on the kidney toxicity of mice, explore its possible toxic mechanism, and provide some basis for clinical rational drug use and further research.

Method:

The 30 Kunming mice, half male and half female, were randomly divided into 3 groupscontrol group, emodin low dose group and emodin high dose groups (0.8, 1.6 g·kg-1), 10 mice in each group. Continuous intragastric administration was given for 11 weeks. During administration, the general situation of the mice was observed and recorded. After treatment, the serum urea nitrogen (BUN), creatinine (SCr), malondialdehyde (MDA), superoxide dismutase (SOD) tumor necrosis factor (TNF-α) and interleukin-6 (IL-6) were detected. Kidney index was calculated and glutathione peroxidase (GSH-Px) and reduced glutathione/oxidized glutathione (GSH/GSSG) ratio were measured. The kidneys were taken for histopathological examination and the protein expression levels of transforming growth factor-β1(TGF-β1) and cysteine aspartic acid specific protease-3 (Caspase-3) were then detected by immunohistochemistry assay.

Result:

As compared with control group of the same sex, the weight of mice in the administration groups was decreased significantly, renal index was decreased while BUN and SCr levels were increased significantly (PPPPα was increased significantly (PP PP

Conclusion:

The long-term administration of emodin at a large dose would show toxicity effect on mice kidney, and the toxicity was obvious at the dose of 1.6 g·kg-1·d-1, but there was no significant difference between the sexes. The mechanism of its potential toxicity may be related to the disorder of oxidation system, the injury of oxidative stress, the triggering of inflammatory reaction, and the apoptosis of cells.
