Introduction
This study investigated the protective effects of antcin C against cerebral haemorrhage injury.

Material and methods
Cerebral haemorrhage was treated with antcin C 100 mg/kg i.p. at 60 min after the induction of cerebral injury. Neurological scores and volumes of cerebral injury were assessed to determine the effects of antcin C, based on oxidative stress and serum mediators of inflammation by ELISA. qRT-PCR was used to estimate the mRNA expression of Toll-like receptor 4 (TLR-4) and interleukin-1 receptor-associated kinase 4 (IRAK4) proteins in the cerebral tissue of rats with cerebral haemorrhage. Western blot assay and histopathology were also performed.

Results
The findings suggest that treatment with antcin C reduced the neurological scores and volumes of cerebral injury in cerebral injured rats. Parameters of oxidative stress and cytokine levels were reduced in the serum of the antcin C-treated group compared with the negative control group. Treatment with antcin C ameliorated the expression of TLR-4, IRAK4, and zonula occludens-1 (ZO-1) proteins in the cerebral tissue of cerebral injured rats.

Conclusions
The results revealed that treatment with antcin C protected against cerebral haemorrhage damage by controlling microglia inflammation through the TLR-4 pathway.
