OBJECTIVE:To establish a gas chromatography(GC)method for determination of seven residual solvents in clofarabine.METHODS:The capillary column was AT-1301;the carrier gas was nitrogen gas and the detector was FID.By temperature programming was applied for the column temperature with an initial temperature of 40 ℃,which rose to 80 ℃ with an increase rate of 7 ℃?min-1,then rose to 200 ℃(kept at this temperature for 2 min)with the increase rate of 20 ℃?min-1.The injector temperature was 250 ℃ and the detector temperature was 280 ℃.The sample was injected directly for determination of residual levels of methanol,acetonitrile,dichlormethane,t-butyl alcohol,ethyl acetate,n-heptane and acetic acid in 3 batches of clofarabine.RESULTS:All the organic solvents were effectively separated and they showed good linearity within a concentration range(r=0.999 41~0.999 93)with average recovery rate ranged from 96.5% to 102.4%(RSDs of all were less than 4.0%).7 kinds of organic solvents in 3 batches of samples were all up to the standard specified in Chinese Pharmacopeia.CONCLUSION:The method is sensitive,accurate and reliable,and it is applicable for the determination of the residual solvents in clofarabine.

Objective To observe the effects of quercetin on PGE 2 release and cyclooxygenase activity in IEC 6 cells stimulated by the serum of burned rats. Methods The PGE 2 levels were measured by radioimmunoassay and the changes of cyclooxygenase activity were determined by substrate fluorescence analysis. Results Stimulated by the serum of burned rats, the PGE 2 level increased first and then obviously decreased. Quercetin at 0.1 and 1.0 ?mol/L enhanced the PGE 2 level after the stimulation of IEC 6 cells for 24 h. There was no obvious change in total cyclooxygenase activity, but the activity ratio of COX 1 to COX 2 significantly decreased. Conclusion Quercetin might influence the release of cyclooxygenase metabolite PGE 2 through the regulation of COXs activity in IEC 6 cells.

<p><b>OBJECTIVE</b>To investigate the changes of the mRNA expression and the intestinal mucosal cyclooxygenase (COXs) activity in scalded rats.</p><p><b>METHODS</b>Wistar rats inflicted with 30% TBSA III degree scalding were employed as the model. The changes of COX-1, COX-2 activities were determined by substrate fluorescence analysis and the mRNA expressions of COX-1 and COX-2 by RT-PCR.</p><p><b>RESULTS</b>The mRNA expressions and the activities of COX-2 in rat intestinal mucosa increased obviously after injury. But those of COX-1 exhibited lower range of change.</p><p><b>CONCLUSION</b>The pathological mechanism of rat intestinal mucosa injury after scalding might be closely related to the COXs participation by different styles between the two enzymes.</p>
