Background: The aim of the present study was to investigate the effect of N-acetylcysteine on intestinal reperfusion injury.
Methods: Forty Sprague-Dawley rats were divided into four groups (n = 10): sham, sham + N-acetylcysteine, reperfusion, and reperfusion + N-acetylcysteine. Thirty minutes of ischaemia +/- 30 min of reperfusion was performed under 100 mg/kg N-acetylcysteine or placebo, administered 30 min before the operation in the groups where appropriate. Ileum samples were resected for histopathologic evaluation and tissue malondialdehyde and super oxide dismutase level determination.
Results: The mean mucosal injury score and malondialdehyde level of the reperfusion and reperfusion + N-acetylcysteine groups were significantly higher than that of the control and control + N-acetylcysteine group (P < 0.01, P < 0.05, respectively). Mean super oxide dismutase level of the control + N-acetylcysteine group was significantly higher than that of the other groups (P < 0.05).
Conclusion: N-Acetylcysteine did not prevent intestinal reperfusion injury by means of histopathologic findings and malondialdehyde level.

Cerebral ischemia-reperfusion injury (CIRI) is clinically characterized by high rates of morbidity, disability, mortality, and recurrence as well as high economic burden. The clinical manifestations of CIRI are often accompanied by gastrointestinal symptoms such as intestinal bacterial dysbiosis and gastrointestinal bleeding. Gut microbiota plays an important role in the pathogenesis of CIRI, and its potential biological effects have received extensive attention.

This paper explored the protective effect and potential mechanism of Shouhui Tongbian Capsules(SHTB) on cerebral ischemia-reperfusion rat models. Rats were randomly divided into sham surgery group, model group, low-dose SHTB group(0.2 g·kg~(-1)·d~(-1)), high-dose SHTB group(SHTB g·kg~(-1)·d~(-1)), and an edaravone positive drug group(5.

Using autologous orthotopic liver transplantation (AOLT) model in rats, the effect of lipid reactive oxygen species (L-ROS) inhibitor Ferrostain-1 on ferroptosis signal pathway was observed to determine whether ferroptosis occurred in rat liver injury after cold ischemia-reperfusion (I/R). Thirty-two healthy adult SPF male SD rats, 8 ~ 10 weeks old, weight 240 ~ 260 g, were divided into four groups by the method of random number table (n = 8): sham group, I/R group, I/R + Fer-1 group, I/R + DFO group. In the I/R + Fer-1 group, ferristatin-1(5 mg /kg) was intraperitoneally injected 30 min before surgery; in the I/R + DFO group, DFO 100 mg/kg was injected intraperitoneally 1 h before operation and 12 h after operation.

Background: Intestinal ischemia affects the functioning of the Enteric Nervous System (ENS). Pannexin-1 channel participates in cell communication and extracellular signaling. Probenecid (PB) is a pannexin-1 channel inhibitor, which can be a potential treatment for intestinal ischemia.

Ferroptosis is a classic type of programmed cell death characterized by iron dependence, which is closely associated with many diseases such as cancer, intestinal ischemic diseases, and nervous system diseases. Transferrin (Tf) is responsible for ferric-ion delivery owing to its natural Fe binding ability and plays a crucial role in ferroptosis. However, Tf is not considered as a classic druggable target for ferroptosis-associated diseases since systemic perturbation of Tf would dramatically disrupt blood iron homeostasis.
