Aim To establish a rapid and sensitive diagnostic markerfor adjusting gut absorptive capacity after trauma. Methods A mi-cromethod for D-xylose test with phloroglucinal was established according toEberts with modification. The standard curves were repeated for fivetimes. Then the blood contents of fasting and orally taking 0. 5 g/kgD-xylose at 2nd and 4th hour were measured and the blood D-xylose con-tents of seven refilling rats with ischemia of intestine were mea-sured. Results The maximal absorption spectra was read at 554 nm byscanming of DU-7 Beckman. Good linearity of the D-xylose standard curvewas found with the range of 0 to 4 mmol/L(r=0. 9979 ±0. 0017) . Theblood content of rats at 2nd hour after orally taking D-xylose was ( 154 ± 6)mg/L amd that at 4th hour was decreased to (87 ± 11) mg/L. And theblood content at 2nd and 4th day after ischemic refilling was (162 ± 5)mg/L and (80 ± 8) mg/L respectively. The variation coefficients within andamong batches were 1.98% (n=6) and 3.10% (n=6), respective-ly. And D-xylose recovery rates were from 97.2% to 104. 3%. ConclusionMicromethod for D-xylose test appears to be simple, rapid and sensitive,and is an available index for estimating intestinal absorption after severetrauma.

ObjectiveTo determine a measurement standard of irregular scar area by comparing the ad-vantages and disadvantages of different measurement methods in measuring same irregular scar area. MethodsIrregular scar area was scanned by digital scanning and measured by coordinate reading method, AutoCAD pixel method, Photoshop lasso pixel method, Photoshop magic bar filled pixel method and Foxit PDF reading software, and some aspects of these methods such as measurement time, repeata-bility, whether could be recorded and whether could be traced were compared and analyzed.Results There was no significant difference in the scar areas by the measurement methods above. However, there was statistical difference in the measurement time and repeatability by one or multi performers and only Foxit PDF reading software could be traced back.ConclusionThe methods above can be used for measuring scar area, but each one has its advantages and disadvantages. It is necessary to develop new measurement software for forensic identification.

Objective: To prepare Danshen Injection (Radix Salviae Miltiorrhizae) by micelle-ultrafiltration. Methods: For preparing Danshen Injection, we packed the impurities in the macrofiltered liquor of Radix Salviae Miltiorrhizae with micelle of Tween-80, and ultrafiltered the compounds with ultrafiltration membrane withholding molecular weight more than 50000. Then we evaluated the process with the comprehensive indexes including loss rate of UV absorbance, loss rate of Protocatechualdehyde and the stability of transparence. Conclusion: The process of Danshen Injection prepared by micelle-ultrafiltration is better than that of ordinary ultrafiltration.
