Drug preparation and administration were previously described by Zhong et al.28 (link) Briefly, 20 mg bexarotene (Selleck, Shanghai, China) was dissolved in 5.7 ml
dimethyl sulfoxide (DMSO), and 51.3 ml phosphate-buffered saline (PBS) was added to the
mixture. Similarly, 10 mg GW9662 (Selleck), an inhibitor of PPARγ was dissolved in 3.6 ml
DMSO, and PBS (32.4 ml) was added to the mixture. A total of 10 mg of MK886 (Selleck), an
antagonist of FLAP was dissolved in 2.1 ml DMSO, and 18.9 ml PBS was added to the mixture.
The final concentrations of GW9662, MK886 and bexarotene were the same (1 mM). The
solution was injected intraperitoneally at 5 mg/kg bexarotene, 2 mg/kg GW9662, and 3 mg/kg
MK886 per day after SAH. The vehicle group solution was prepared in the same manner and
administered in the same volume, same route and same time course as above. These reagents
were used immediately after SAH and continued to be used once a day until the rats were
euthanized.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
