Abstract:
Aim To investigate the effects of osthol on cell apoptosis and inflammatory cell infiltration after brain stab wound injury in mice. Methods The mice underwent the stab wound injury by a needle, then were randomly divided into sham operation group, model group, osthol 10, 20, 30 mg · kg-1 treatment group. The main examinations included mice brain wa-ter content; the apoptotic cytokines Bax, Bcl-2, Caspase-3 mRNA expression were assessed by PT-PCR; immunohistochemistry staining was used to de-tect neutrophils (MPO) and microglia (Iba-1) infiltra-tion and Caspase-3 positive cell expression around in-jured lesions. Results Treatment with osthole 20, 30 mg·kg-1 group significantly reduced the water content in injured brain, improved the ratio of Bax/Bcl-2, and reduced the expression of apoptosis cytokine Caspase-3 mRNA. Osthole 30 mg·kg-1 treatment group obvious-ly reduced the infiltration of neutrophils and microglial cells and significantly reduced the number of apoptotic cells around the injured cerebral cortex. Conclusion Osthole has therapeutic effect on stab wound injury in mice, and the possible mechanism may be by reducing the infiltration of inflammatory cells and reducing apop-totic cells.
