2 experimental techniques
1) the PC-12 cell carries out cellar culture (10cm culture dish) with DMEM+10%FBS in 37 ℃, 5%CO2, when Growth of Cells during to logarithmic (log) phase, collecting cell discards culture fluid, PBS fine laundering 3 times, add 3ml0.25% trypsin-0.04%EDTA, after 37 ℃ of digestion 2min, add wherein 5ml complete medium neutralization reaction, after the piping and druming cell, it is changed in centrifuge tube, the centrifugal 5min of 1000rpm adjusts 3 * 104/ml of concentration of cell suspension.
2) the cell kind is entered in 96 well culture plates, every hole adds cell suspension 180 μ l, culture plate put into cell culture incubator (37 ℃, 5%CO2) cellar culture.
3) according to the Growth of Cells situation, generally grow to 50%-70%, add Qingnao Jiangyapian solution, continue to cultivate 24h.
4) add 20 μ l MTT solution (5mg/ml, i.e. 0.5%MTT) after 24h, continue to cultivate 4h.
5) after 4h, the buckle method is removed supernatant, pats dry gently with absorbent paper, and every hole adds 200 μ l dimethyl sulfoxide, puts low-speed oscillation 10min on shaking table, and crystal is fully dissolved.Light absorption value in each hole of measurement, enzyme-linked immunosorbent assay instrument 490nm place.6) background (do not add cell, only add culture fluid) is set simultaneously, control wells (the medicine dissolution medium of cell, same concentrations, culture fluid, MTT, dimethyl sulfoxide) is set 6 multiple holes for every group.
7) result represents with the suppression ratio of medicine to cell:
Cell increment suppression ratio (%)=(control wells OD value-dosing holes OD value)/control wells OD value * 100%.Experiment repeats 3 times.
3 statistical dispositions
Adopt correlation analysis and Student t check in Microsoft Excel2003 software, data represent with mean ± S.D..
4 experimental results
Statistical result showed after the mtt assay experiment, compare with matched group, when dosage reaches 5mg/ml, to PC-12 cell inhibitory effect variant (P＜0.05), dosage this difference when 10mg/ml has significance (P＜0.01), and utmost point significant difference (P＜0.001) is arranged when dosage reaches 15-20mg/ml.
Table 1 Qingnao Jiangyapian affects the PC-12 cell inhibitory effect and grinds
Annotate: compare * P＜0.01 with matched group; * P＜0.001
