Objective To summarize the causes and re-surgical methods of early intracranial hypertension in- duced by operation in meningeal neoplasms. Methods Analysize the re-surgical materials about the early intracranial hypertension induced by operation in meningeal neoplasms of 16 cases. Results The formation of hematoma or the appearance of tension injury after the surgery of meningeal neoplasms was related to the location and quality of the tumor. The reasons for these were as follows. The tension injury often happens in 48 ～ 72h after surgery. The time needed by the operation of hernatoma is changeable. The decreasing level of consciousness was the major expression of intracranial hypertension after surgery. Conclusion Watch the conditions of meningeal neoplasms after operation. Do the image examination if needed. So it is easy the final and deal with the hematoma or the cerebral edema.

OBJECTIVE:To establish an UV-spectrophotometry method for determination of glutaraldehyde in solution METHODS:The concentration of glutaraldehyde in solution was measured at 233nm wavelength which was characteristic absorption peak of glutaraldehyde RESULTS:The calibration curve was linear within the range of 100～1 600?g/ml with r=0 9 998(n=5) The relative standard deviation of the measured results was≤2 13%(n=6) CONCLUSION:The method is simple,rapid and accurate
