Method: We studied 128 patients who had undergone transradial angiography in our center from December 2009 to April 2010. Among them,64 patients were randomly treated with radial compression device ( TR-BAND,Terumo) when the procedure was over ( CD group) . The other 64 patients were dealt with chitosan ( CS group) . The compression time,the major and minor access site bleeding complications and the errhysis were observed. Results: There were no statistical differences in the baseline clinical characteristics of the patients between two groups. The compression time in CS group was significantly shorter than that of CD group ( P < 0. 001) . There were 12 patients suffering from minor access site bleeding while only 3 patients experienced these minor complications in CS group( 19% vs 4% ,P < 0. 05) . At the same time 20 patients had er- rhysis in CD group and 4 patients in CS group ( 31% vs 6% ,P < 0. 001) . Conclusion: Chitosan,compared to radial compression device ( TR-BAND,Terumo) ,can not only shorten the compression time,but also significantly reduce the rate of minor access site bleeding and puncture-site errhyis.展开更多

The role of reduced glutathione (GSH) in the clearance of Hg was also investigated to e valuate the ameliorative effect of this nucleophile. For this purpose, the perch was given GSH 15 min before or after they received 203Hg by injection. The fish were then sacrificed at 24 h and 48 h later. The results clearly indicate that exogenous GSH can significantly reduce Hg retention in both the liver and kidneys, demonstrating a direct role of this nucleophile in the amelioration of Hg-induced toxicity in the early phase of intoxication展开更多
