RESUMO
Objective To investigate the change of neuropeptide Y(NPY)and neurotensin(NT)in pqtients with brain glioma.Method The concentration of NPY and NT in and around brain glioma tissue and plasma were detected with inequilibrant radio－ imunology method.Result NPY concentrqtion in brain glioma tissue was obviously higher than that in tissue around the tumor(P<0.01).The Concentration of NT in brain glioma tissue was obviously higher that in tissue around the glioma(P<0.01).Conclusion Detection of NPY and NTin brain glion aprovides basis for further study on brain glioma and explainning dlinical and imaginal symiptom of brain glioma.
RESUMO
OBJECTIVE:To determine the concentration of AstragalosideⅣin Yishenkangshuai tablet.METHODS:The sample was separated by using chloroform-ethyl acetatemethanol-water(15∶40∶22∶10)on the silica gel plates.The plate was scanned at510nm by camagⅡTLC scanner.RESULTS:The rate of recovery was99.28%and RSD was2.5%.CONCL_ USION:The method is simple,quick and repeatable.
