Background technology
Chemical damage is a kind of common liver disease, mainly caused by the series damage caused by oxidative stress, such as weight
Depending on inadequate, hepatitis, liver fibrosis, hepatonecrosis, or even hepatic sclerosis and liver cancer are easily evolved into, Medical bound pair is in chemically liver
Damage no preferable therapeutic strategy.However, a variety of active ingredients found from Chinese medicine has obvious prevention and treatment liver
The effect of damage.Therefore, find and find with prevention and treatment chemical damage preparation with certain from natural drug
Theory significance and realistic meaning.
European bird cherry platymiscium is various in China's species, is perennial arbor, is planted extensively in China, because cold-resistant shade tolerant is in northeast
Area growth is intensive.Mainly include mountain peach european bird cherry(Padus maackii), star hair european bird cherry(Padus buergeriana), european bird cherry
(Padus racemosa), brown hair european bird cherry(Padus brunnescens)And purple leaf european bird cherry(Padus virginiana)Deng.
It is a kind of important to view and admire species in China because the platymiscium is overall beautiful.Wherein mountain peach european bird cherry, european bird cherry and purple leaf european bird cherry are rose
Common vetch section cherry, it is distributed more widely in northeast.
Research shows:The leaf of european bird cherry platymiscium can be used for making product(Bird cherry leaf tea and preparation method thereof, patent,
ZL. 200610010198.7), flower containing substantial amounts of benzaldehyde because that can do anti-corrosion materials(Zhao Qiuyan, european bird cherryPrunus padusLinn. volatile oil chemical composition analysis,《Plant research》, 2003), in addition, the abundant flavones ingredient that european bird cherry contains
(He Yingxia, the optimal extraction technology of flavones in purple leaf european bird cherry blade《Northern gardening》, 2013)And anthocyanin type components(It is pungent
More, european bird cherry belongs to three kinds of fruit anthocyanin antioxidant activity researchs, Northeast Forestry University's Master's thesis, 2013).Above-mentioned document report

Experimental animal
SPF grades of ICR mouse, male, weight 20-22g, purchased from this experimental animal technology Co., Ltd of Changchun hundred million,
Quality certification number:SCXK(It is lucky)2011-0004, adaptability are tested after raising 1 week.
Adaptability feed 1 week after male ICR mouse, be randomly divided into 6 groups, i.e. blank control group, model group, silymarin
Positive controls(150 mg·kg-1), european bird cherry extract low dose group(100mg·kg-1), middle dose group(200mg·kg-1)
With high dose group(400mg·kg-1).Positive controls and administration group use gastric infusion, continuous 7 days, blank control group and mould
Type group gives isometric physiological saline, and after 1 h of last dose, in addition to blank group, remaining each group disposably gives volume fraction
For 50% alcohol, by 4.8gkg-1(12mL/kgbw) inducing acute alcoholic liver injury, fasting for solids but not liquids.6 it is small when after eye
Socket of the eye veniplex is taken a blood sample, separation serum, and after 12h, cervical dislocation puts to death mouse, quickly removes each group liver and spleen, weighs, and calculates liver and refers to
Number and spleen index (internal organs weight/weight × 100%).
Experimental result
The influence of 2.1 pairs of mouse weights and organ index
As it can be seen from table 1 after being administered 7 days, each group the weight of animals increased, but each administration group and blank control group
Compared to weight without significant difference (P> 0.05), show that european bird cherry extract does not influence mouse weight.Research shows:Disposably
Heavy dose of alcohol impact can cause the significantly raised of mice organs index, mainly include liver index and spleen index.This experiment is tied
Fruit shows:Compared with blank group, model group mouse liver index and spleen index dramatically increase (P< 0.05), and with administration 7 days after,
Two administration groups of european bird cherry extract and silymarin administration group can degree reduction liver index and spleen index (P<
0.05), as a result such as following table.
Influence of the 1 european bird cherry extract of table to mouse weight and Immune Organs Index(,n=8)
" * " model group is compared with blank control group, and " # " administration group is compared with model group, significant difference(P<0.05).
The influence of ALT, AST and TG level in 2.2 pairs of mice serums
From table 2 it can be seen that compared with blank control group, the level of ALT, AST and TG of model group substantially increase, and say
Bright acute alcohol induced liver injury model creation success(P<0.05);Compared with model group, various dose european bird cherry extract is given
(200 and 400mg/kg)Each group mice serum in ALT, AST and TG content substantially reduce, there is statistical significance(P<
0.05), and ALT and AST is on close level the level of positive controls in high dose group.The result shows that:European bird cherry extract energy
The rise of enough different degrees of suppression acute alcohol hepatic injury mouse ALT, AST and TG levels, as a result such as following table.
Influence of the 2 european bird cherry extract of table to mice serum ALT, AST and TG content(,n=8)
" * " model group is compared with blank control group, and " # " administration group is compared with model group, significant difference(P<0.05).
The influence of MDA and GSH levels in 2.3 pairs of murine liver tissues
From table 3 it can be seen that compared with blank control group, the MDA levels of model group are significantly raised, and GSH contents are shown
Write and decline, illustrate that disposable heavy dose of alcohol impact can cause oxidativestress damage, show acute alcohol induced liver injury mould
Type is successfully established(P<0.05);Compared with model group, the MDA water of two dosage group mouse of european bird cherry extract 200 and 400mg/kg
It is flat gradually to be reduced with the increase of dosage, and have significant difference(P<0.05);And the content of GSH is with giving european bird cherry
The increase of extract doses has been lifted and has been in certain dose relationship(P<0.05).The result shows that:European bird cherry extract can
The oxidativestress damage of acute hepatic injury mice generation is effectively improved, as a result such as following table.
Influence of the 3 european bird cherry extract of table to mouse liver MDA and GSH(,n=8)
" * " model group is compared with blank control group, and " # " administration group is compared with model group, significant difference(P<0.05).
2.4 pairs of murine liver tissue pathology section examinations
Pathology of hepar is observed as shown in the figure, normal mouse liver histocyte marshalling, nuclear structures and
Phenomena such as cell boundaries are clear, cell rope aligned orderly, fat-free degeneration necrosis, no inflammation cellular infiltration;The visible liver of model group
Iuntercellular boundary obscures, and central vein expands, and occurs inflammatory cell infiltration and a large amount of denaturation vacuoles, part of hepatocytes core into the cell
Phenomena such as atrophy or disappearance;Compared with model group, milk thistle positive controls hepatic injury has a significant mitigation, liver cell structure and
Liver rope is arranged substantially close to normal, no inflammatory cell infiltration and lipid vacuole;After european bird cherry extract for treating is given 7 days, mouse
In liver cell, it can clearly be seen that swelling and cracking degree mitigate, inflammatory cell infiltration and denaturation vacuole are reduced, but still visible
Part apoptotic cell and denaturation vacuole, figure omit
