Abstract:
Objective To investigate the productive effects of baicalin on the male rats with ischemic brain injury and its effects on serum progesterone level in rats; To explore the possible mechanism of baicalin in brain protection. Methods Adult SD male rats were used to create a permanent left middle cerebral artery occlusion model. The rats were evenly divided into model group, baicalin group, inhibitor group, and sham-operation group (without inserted into the intraluminal thread) according to the neurological function scores. At different time points after modeling, the neurological function scores and the grip strength of double foreleg were measured, and the reduction rate of grip strength was calculated. Serum progesterone and adrenocorticotrophic hormone (ACTH) were detected by ELISA. Results Compared with the sham-operation group, the neurological function of rats in the model group was impaired, the grip strength of double foreleg was significantly reduced. 7 days after treatment, compared with the model group, the neurological function score of baicalin group was lowered, grip strength of double foreleg was recovered, reduction rate of grip strength was reduced (P<0.05); compared with the baicalin group, protective effects of baicalin on neurological function was lowered in inhibitor group (P<0.05). 7 days after treatment, compared with the model group, the serum progesterone level in baicalin group was significantly higher (P<0.01), and ACTH level showed an increasing trend; compared with the baicalin group, serum progesterone and ACTH levels in the inhibitor group decreased (P<0.05). Conclusion The protective effects of baicalin on the male rats with ischemic brain injury may be related to the regulation of progesterone.
