Abstract

This study explored the effect of coral calcium hydride (CCH) on rat intrahippocampal antioxidant ability by measuring the PCAM nitroxide radical decay ratio when CCH was (a) co-perfused into the hippocampus and (b) fed orally to the rats for 4 weeks under a freely moving state. Estimation of the in vivo antioxidant effect was obtained by administration of the blood-brain barrier-permeable PCAM nitroxide radical and the measured PCAM radical decay ratio then correlated to the amount of antioxidant in the brain using electron spin resonance (ESR) spectroscopy combined with microdialysis. The half-life periods of PCAM in rats treated with CCH in both the co-perfusion and orally fed groups were significantly shorter compared to the control group. These results clarify the mechanism that CCH may exert antioxidant activity by significantly enhancing the basal endogenous antioxidant ability in the hippocampus through a synergistic effect with α-tocopherol and ascorbic acid.

Blood Brain Barrier Regulation in Health & Disease

The blood brain barrier is essential in regulating the movement of molecules and substances in and out of the brain. Disruption to the blood brain barrier and changes in permeability allow pathogens and inflammatory molecules to cross the barrier and may play a part in the pathogenesis of neurodegenerative disorders. Here is the latest research in this field.

Blood Brain Barrier

The blood brain barrier is a border that separates blood from cerebrospinal fluid. Discover the latest search on this highly selective semipermeable membrane here.

Blood Brain Barrier Chips

The blood brain barrier (BBB) is comprised of endothelial cells that regulate the influx and outflux of plasma concentrations. Lab-on-a-chip devices allow scientists to model diseases and mechanisms such as the passage of therapeutic antibodies across the BBB. Discover the latest research on BBB chips here.
