Crocin attenuates hemorrhagic shock-induced oxidative stress and organ injuries in rats

Publication date: Available online 13 April 2017 Source:Environmental Toxicology and Pharmacology Author(s): Long Yang, Xiujuan Dong We aimed to evaluate the effect of natural antioxidant crocin in alleviating hemorrhagic shock (HS)-induced organ damages. HS rats were treated with crocin during resuscitation. Mortality at 12h and 24h post resuscitation was documented. HS and resuscitation induced organ injuries, as characterized by elevated wet/dry ratio, quantitative assessment ratio, blood urea nitrogen, creatinine, aspartate aminotransferase and alanine aminotransferase, whereas rats received crocin treatment demonstrated improvements in all the above characteristics. This protective effect coincided with reduced malondialdehyde and increased glutathione in both serum and lung tissues, indicating attenuated oxidative stress in crocin-treated rats. Myeloperoxide levels in lung, kidney and liver were also reduced. Crocin can potentially be used to protect organs from HS-induced damages during resuscitation due to its anti-oxidative role.
