When rats were treated with a high dose (greater than or equal to 20 micrograms/100 g BW) of dexamethasone, their liver cytosol showed a predominant peak of specific binding protein of glucocorticoid eluting with 0.13-0.14 M NaCl on diethylaminoethyl cellulose chromatography. On the other hand, when rats were treated with a low dose (approximately 2… (More)
Previously a new glucocorticoid receptor (Peak C), which eluted with 0.12 to 0.14 M NaCl from DEAE-cellulose column, was identified in addition to another receptor (Peak B), a classic type of glucocorticoid receptor, which eluted with 0.05 to 0.08 M NaCl. Peak C appeared after stress or injection of a high dose (20 micrograms/100 g body weight) of… (More)
Thin-layer polyacrylamide gel electrophoresis of various rat tissues revealed three major isozymes (types L, M1 and M2) and various intermediate forms of pyruvate kinase (ATP: pyruvate 2-O-phosphotransferase, EC 18.104.22.168). In vitro dissociation and reassociation of purified enzymes showed that the three major isozymes had homotetrameric structures. L.M2… (More)
BACKGROUND We previously demonstrated that intracellular calcium propagation was induced by stimulation of epidermal keratinocytes in skin slices or in culture with adenosine triphosphate (ATP). The feature of the calcium wave propagation appeared to be different between differentiated cells and proliferating cells, and so the mechanisms involved might be… (More)
A number of 3-(1H-tetrazol-5-yl)chromones were synthesized and found to have antiallergic activity in the rat passive cutaneous anaphylaxis (PCA) test. These compounds are active when administered orally in rats and of possible value for the treatment of asthma.
