Neuroprotection by the Traditional Chinese Medicine, Tao-Hong-Si-Wu-Tang, against Middle Cerebral Artery Occlusion-Induced Cerebral Ischemia in Rats
Inhibition of the free radical-scavenging activity by Tao-Hong-Si-Wu-Tang (THSWT) in the /NaOH/DMSO system. The signal of hydroxyl radical peaks was observed in electron spin resonance (ESR) experiments. (a) Resting spectrum (without ), (b) typical ESR spectra in the presence of solvent control (distilled water), (c) THSWT (20 g ), and (d) (40 g ) in the /NaOH/DMSO system. The spectrum is a representative example of four similar experiments. An asterisk () indicates formation of hydroxyl radicals.
