RESUMEN
Objective To study the protection effect of dexmedetomidine and ulinastatin on acute lung in-jury caused by hepatic ischemia reperfusion. Methods 50 rats were randomly divided into 5 groups: the blank group, saline group, the dexmedetomidine group, the ulinastatin group, the dexmedetomidine and ulinastatin group. Ischemia-reperfusion models were established and drugs were administrated through femoral vein. The levels of MDA, SOD and ICAM were detected. Results Compared with the blank group, the rest of the groups of PaO2, pH and SOD activity were significantly lower (P < 0.05), and BE, pathological grading, MDA, ICAM levels were significantly higher (P<0.05). PaO2, pH and SOD activity of ulinastatin group were significantly lower in the phys-iological saline group (P < 0.05), BE, pathological grading, MDA level, ICAM levels were significantly elevated in the physiological saline group (P<0.05). Conclusion Combination of dexmedetomidine and ulinastatin have protection effect on acute lung injury caused by hepatic ischemia reperfusion, its mechanism may be related to in-hibit neutrophil aggregation, improve their antioxidant capacity and inhibition of lipid peroxidation.
RESUMEN
OBJECTIVE:To prepare Sophora alopecurodies suppository for treating prostatitis chronica and observe its clinical therapeutic effect METHODS:The content of the total alkaloid in the suppository was determined with acid dye spectrophotometry and the therapeutic effect was observed in comparison with qianliean suppository RESULTS:The linear range of TASa was 0 14～15 4?g/ml,standard oxymatriner's recovery was 101 2%,RSD=0 55% CONCLUSION:This suppository is simple in preparation,reliable in quality-control It is slight in irritation to rectum and effective in clinical use The preparation is worth popularizing in clinical practice
