We estimated the nutritional availability of selenium (Se) in Se-enriched Kaiware radish sprouts (SeRS) by the tissue Se deposition and glutathione peroxidase (GPX) activity of rats administered the sprouts, and examined the effect of SeRS on the formation of aberrant crypt foci (ACF) in the colon of mice administered 1,2-dimethylhydrazine (DMH) to evaluate(More)
TFC-612 inhibited thrombus formation on wire coils inserted into the lumen of the inferior vena cava of rats after 5 oral doses of 1.0 and 3.2 mg/kg and subcutaneous doses of 1.0 and 3.2 micrograms/rat/hr. This compound showed slight inhibition of platelet aggregation induced by collagen at 1.0 and 3.2 mg/kg (po) and significant inhibition at 10 mg/kg.(More)
The anti-platelet activities of TFC-612, methyl 6-(( 1R,2S,3R)-3-hydroxy-2-((1E,3S,5R)-3-hydroxy-5-methyl-1-nonenyl)-5- oxocyclopentyl) thio)hexanoate, were compared to prostaglandin E1 (PGE1). TFC-612 inhibited human, guinea-pig and rabbit platelet aggregation induced by ADP, collagen or epinephrine with potency 1-8 times that of PGE1. TFC-612 also(More)
The anti-platelet actions of 1-[(4,5-bis(4-methoxyphenyl)-2- thiazoyl)carbonyl]-4-methylpiperazine hydrochloride (FR122047) were investigated in vitro and in vivo. FR122047 was 100 times more potent than aspirin against arachidonic acid- and collagen-induced human and guinea-pig platelet aggregation in vitro. Its actions on platelets were a result of(More)
