Serofendic acid is a low-molecular-weight compound extracted from fetal calf serum. We previously reported that intracerebroventricular administration of serofendic acid prevents cerebral ischemia-reperfusion injury. However, the effect of peripheral administration of serofendic acid on cerebral ischemia-reperfusion injury has not been examined. In the present study, we investigated the effect of intravenous administration of serofendic acid against cerebral ischemia-reperfusion injury using transient middle cerebral artery occlusion model rats. Serofendic acid (10mg/kg) administrated three times, including 30min before the onset of ischemia, just after the onset of ischemia and just before reperfusion reduced the infarct volume and improved the neurological dysfunction induced by ischemia-reperfusion without affecting regional cerebral blood flow or physiological parameters. However, there were no protective effects when serofendic acid (30mg/kg) was only administered once at 30min before the onset of ischemia, just after the onset of ischemia, or just before reperfusion. Our results reveal the importance of maintaining the blood concentration of serofendic acid for preventing cerebral ischemia-reperfusion injury.

UI MeSH Term Description Entries
D008297 Male Males
D001921 Brain The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM. Encephalon
D002545 Brain Ischemia Localized reduction of blood flow to brain tissue due to arterial obstruction or systemic hypoperfusion. This frequently occurs in conjunction with brain hypoxia (HYPOXIA, BRAIN). Prolonged ischemia is associated with BRAIN INFARCTION.

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D018696 Neuroprotective Agents Drugs intended to prevent damage to the brain or spinal cord from ischemia, stroke, convulsions, or trauma. Some must be administered before the event, but others may be effective for some time after. They act by a variety of mechanisms, but often directly or indirectly minimize the damage produced by endogenous excitatory amino acids.
