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

- Crocin reduces HS induced organ injuries.
- Crocin attenuates HS-induced oxidative stress.
- Crocin has potential to treat HS.

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 12 h and 24 h 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.
