Reactive Oxygen Scavenger Effect of Pyrimidines, Benzotriazoles and Related Compounds
No full textFree radicals and reactive oxygen metabolites have been implicated as important pathologic mediators in many clinical disorders and diseases. An efficient method of detecting the free radical scavenger effect is through xanthine oxidase (XO) inhibition. The inhibition efficiency on XO has been detected as the rate of uric acid production, which has max 295 nm. Sulfasalazine showed potent inhibiting activity on XO (IC50 = 25.11muM ; Ki = 50.88muM) and induced a mixed-type (noncompetitive-uncompetitive) inhibition of the substrate xanthine. 2-mercapto-4(3H)- quinazolinone (16) and 2-mercaptopyrimidine (4) displayed inhibiting activity on XO with IC 50 = 98.71 and 136.14muM, while apparent inhibition constants (K) were 158 .38 and 62. 46muM respectively. However benzotriazoles showed weak inhibitory effect. The spin-trapping method with 5,5- dimethyl-1-pyrroline N-oxide (DMPO) by electron spin resonance (ESR) detected the presence of O2(-) and OH. It showed that the percentage inhibition for formation of DMPO- OOH for 2-mercapto-pyrimidine and sulfasalazine were 64.78 and 35.09 , but for hydroxylation were 49.51, 38.55, 37.29 for 2-mercapto-4(3H)- quinazolinone, sulfasalazine and 2- mercaptopyrimidine at 500muM, respectively
Optimum Intensities of Ultrasound for Pge(2) Secretion and Growth of Osteoblasts
No full textThis study compared the effects of different intensity ultrasound (US) on osteoblasts in the far-field model with effects of the near-field model from the literature, to understand the relations between prostaglandin E-2 (PGE(2)) and osteoblast growth. We used an in vitro model to investigate the effects of 1-MHz, pulsed 1:4, and five different spatial-average temporal-peak intensity (150, 300, 600, 1200 and 2400 mW/cm(2)) US stimulations in far-field exposure (240 mm) on osteoblasts for 15 min. Optimum intensity in this study was 600 mW/cm(2), and cell density and PGE (2) secretion could be significantly stimulated at this intensity. This research may indicate that the growth of osteoblasts by US stimulation was , at least partly, due to increases in the synthesis and secretion of PGE( 2). This well-controlled model can lead to further research on the biologic mechanisms for US. (C) 2002 World Federation for Ultrasound in Medicine Biology
