Objective To investigate the effect of thiopental on lipopolysaccharide(LPS)-induced activation of nuclear factor kappa B(NF-κB) under different concentration or after different time in rat glioma cells in vitro.Methods The rat C 6 glioma cells were treated with,in the presence or Absence of various concentrations(10-3 mol/L,10-4 mol/L and 10-5 mol/L)of thiopental for 1 h.30 min before harvest,the cells were exposed to LPS(10 ng/ml).The other C 6 cells were treated with 10-5 mol/L thiopental with different time(0.5 h,1 h,2 h,4 h).30 min before harvest,the cells were exposed to LPS(10 ng/ml).Nuclear extracts from C 6 cells were harvested using standard procedures,and the LPS-induced NF-κB expression was determined with electrophoretic mobility shift assays(EMSA) and measured with densitometry(Bio-Rad).Results The width of the bands of NF-κB under thiopental with different concentrations were similar,but they were narrower than that of the control(treated only with LPS),the density was less than that of the control(P<0.05).The width of the bands of NF-κB under thiopental with different time decreased with the time(P<0.05),and they were much narrower and shallower than that of the control(P<0.05),and the density was significantly less than that of the control(P<0.05).Conclusion Thiopental suppressed the activation of transcription factor NF-κB,and the inhibition was concentration-independent but time-dependent.

In present study, standard method and standard operation practice for measuring the activities of influenza neuraminidase and its inhibitors have been established. The accuracy and stability of the method has been evaluated. Standard operation is as following: 10 microL sample, 30 microL neuraminidase and 60 microL substrate are added to one well of a 96-well plate, and then incubated at 37 degrees C for 1 h. The reaction was stopped with NaOH before fluorescence intensity determination. One unit of neuraminidase is defined as the amount of enzyme that produces 1 nmol 4-MU in 1 h under above conditions. The inhibition accuracy is indicated by an uncertainty measurement of 6.51 x 10(-12), and its stability was reaffirmed by determination of oseltamivir acid. In this study, systematic assessment of neuraminidase inhibitory assay not only provided theoretical basis of its application in drug discovery, but also made preliminary attempt to use uncertainty measurement as a parameter in biological measurement.
