Cell death assay results in SHRsp. Cell death in hippocampus and cerebellum samples from SHR-sp. Group 5A was fed with daily PZH until the stroke occurred, while Group 5B was given saline. Hippocampus and cerebellum tissues were sampled when the rats died after stroke. SHRsp treated with PZH (Group 5A) before stroke showed significantly less (* P < 0.05) cell death as compared to those rats without PZH treatment (Group 5B) in both hippocampus and cerebellum.
