Cerebral Ischemic Reperfusion

Cerebral ischemic reperfusion injury (CI/RI) is a critical factor that leads to a poor prognosis in patients with ischemic stroke. It is an extremely complicated pathological process that is clinically characterized by high rates of disability and mortality. Current available treatments for CI/RI, including mechanical and drug therapies, are often accompanied by significant side effects. Therefore, it is necessary to discovery new strategies for treating CI/RI. Many studies confirm that Chinese herbal medicine (CHM) was used as a potential drug for treatment of CI/RI with the advantages of abundant resources, good efficacy, and few side effects. In this paper, we investigate the latest drug discoveries and advancements on CI/RI, make an overview of relevant CHM, and systematically summarize the pathophysiology of CI/RI. In addition, the protective effect and mechanism of related CHM, which includes extraction of single CHM and CHM formulation and preparation, are discussed. Moreover, an outline of the limitations of CHM and the challenges we faced are also presented. This review will be helpful for researchers further propelling the advancement of drugs and supplying more knowledge to support the application of previous discoveries in clinical drug applications against CI/RI.

Pharmacological Preconditioning

The present study was to investigate the effect of pharmacological preconditioning of total flavones of Abelmoschl Manihot (TFA) on cerebral ischemic reperfusion injury in rats. Rat cerebral ischemia/reperfusion injury was induced by occluding the right middle cerebral artery (MCA). The infarct size was determined by staining with 2,3,5-triphenyl tetrazalium chloride (TTC). The serum malonaldehyde (MDA), nitric oxide (NO) and lactate dehydrogenase (LDH) levels were measured by using spectrophotometry; Inducible NO synthase (iNOS) mRNA expression was detected by RT-PCR method. The percentage of cerebral infarction volume was 28.1 ± 0.8 in the model group, while TFA or nimodipine (Nim) pretreatment 36 hours prior to the ischemic insult significantly decreased the infarction volume. Increases of serum LDH activity and MDA level were observed after ischemia/reperfusion, but these changes were inhibited in rats pretreated with either TFA (20, 40, 80, 160 mg/kg) or Nim, indicating a delayed protective effect of TFA preconditioning on cerebral ischemic reperfusion injury. In addition, the serum NO level and the cerebral iNOS mRNA were up-regulated, suggesting a possible mechanism for the protective effect of TFA pretreatment on cerebral ischemic reperfusion injury.
