50mL/LCO2 incubator is sent into, after 37 DEG C are cultivated 48h, adds cytarabine (5 μ g/mL) to suppress the continuation of non-neuron
Growth, measured every 2d half and change liquid, after cultivating 10d, it is seen that typical nerve cell, it is glimmering through β-tubulin monoclonal antibody immunities
Light dyeing shows more than 80% cell for the positive, it is believed that is pure neuronal cell cultures, carries out subsequent experimental research.
(3) class ischemia model is established:Class ischemic mould is established according to OGD/R (missing of sugar and other nutriments) method
Type, cell culture medium are changed to the artificial cerebrospinal fluid without sugar, and temperature is maintained at (30 ± 2) DEG C, and mixed gas is changed to containing 80mL/
LCO2 nitrogen.Class ischemic preconditioning 10min, artificial cerebrospinal fluid is replaced by culture medium and puts back to incubator row reoxygenation again.
(4) flow cytometry count detection:The primary neural cell being inoculated in blake bottle (1 × 10^6 bottles) is divided at random
For 4 groups, one group is non-ischemia group, and another group of reoxygenation 1/2h again after class ischemic preconditioning, is Ischemia Reperfusion group, third and fourth group is
I group and II group for the treatment of are treated, red dragon analgesia piece ethanol extract (I group for the treatment of) and acetic acid second are separately added into after class ischemic preconditioning
Ester extract solution (II group for the treatment of) pretreatment 10min, two of which extract add coordinative solvent dilute with the extract of embodiment 1 respectively
It is interpreted into tablet containing 1mg/ml liquid.Every group of 4 parts of sample.4 groups are washed 5min with 0.01moL/LPBS respectively, totally 3 times, with 0.25%
Cell dissociation into single cell suspension, is added the μ L of 1: 200NF- κ Bp65 polyclonal antibodies 200 by trypsase after centrifuge washing,
37 DEG C are put, 45min, is washed with 0.01mol/LPBS, totally 3 times, supernatant is abandoned in centrifugation, adds the anti-rabbit IgG200 of 1: 50FITC mark
μ L, 4 DEG C are put, 45min, is washed with 0.01mol/LPBS.Another to set two groups of negative control groups, one group is not added with that I is anti-and II is anti-, for glimmering
Luminous intensity baseline correction；Another group of list adds II to resist, and as non-specific binding control, all samples are separately added into 400 μ L,
Machine testing on 0.01mol/LPBS liquid, every part of sample count more than 5000 cells, as a result take average.
1.3 statistical method
As a result represented with x ± s, data compares with variance analysis and t inspections between group.
2 results
Flow cytomery result NF- Κ b/P65 in non-ischemia group neuron basal expression for (1.38 ±
0.56) %, the 1/2h expression significantly rise (P ＜ 0.01) after ischemia-reperfusion.Through red dragon analgesia 2 kinds of extract pretreatments of piece
Afterwards, expression rate is remarkably decreased (P ＜ 0.05), and compared to there is significant difference (P between four groups<0.05).Wherein, Ischemia Reperfusion
Note group has pole significant difference (P compared with treating II group<0.01).Show ethyl acetate extract to ischemical reperfusion injury mould
The protective effect of type is stronger.
The comparison of NF- κ B expression rates between each group of table 1
Note：Compared with non-ischemia group, ##P ＜ 0.01；Compared with ischemia-reperfusion group, * P ＜ 0.05, * * P ＜ 0.01
3 brief summaries
NF- κ B are present in cerebrovascular endothelial cell, nerve cell and spongiocyte, and its expression is bright after cerebral ischemia re-pouring
It is aobvious to increase and closely related with the inflammation mechanism of cerebral ischemia.This experiment investigates red dragon analgesia piece intervention by index of NF- κ B
It is cerebral ischemia re-pouring injured to treat mouse, it is found that it significantly reduces effect in cerebral ischemia perfusion injury to NF- κ B expression, so as to
Reduce damaging action of the inflammation mechanism to ischemia-reperfusion to nerve cell.
Following examples are used to further illustrate the present invention.
