An evaluation of extracts of five traditional medicinal plants from Iran on the inhibition of mushroom tyrosinase activity and scavenging of free radicals.

29 Sep 2009 This study aimed to evaluate the free radical scavenging and inhibition properties of five medicinal plants, including Quercus infectoria Olive., Terminalia chebula Retz., Lavendula stoechas L., Mentha longifolia L., Rheum palmatum L., toward the ... Read more...

Effect of the free radical scavenger edaravone on peripheral nerve ischemia-reperfusion injury.

29 Sep 2009 We investigated the effects of edaravone, a free radical scavenger, on peripheral nerve ischemia-reperfusion injury caused by ligation of vessels supplying the sciatic and tibial nerves in rats. The control group was administered a placebo, the ... Read more...

Modification of mortality and tumorigenesis by tocopherol-mono-glucoside (TMG) administered after X irradiation in mice and rats.

29 Sep 2009 The effects of TMG [2-(alpha-d-glucopyranosyl) methyl-2,5,7,8-tetramethylchroman-6-ol], a water-soluble vitamin E derivative, administered after irradiation on the mortality of X-irradiated mice and on the development of tumors in the mammary and ... Read more...
