Hereinafter, zoopery but is not meant to any limit of the invention to further description of the invention System.Clearly as popularity possessed by selected experimental animal pharmacology feasibility express present invention application should trace back and it is dynamic Object realm.
In the present invention, using 10 week old, the male C57BL/6 mouse of 20~25g of weight, purchased from Changchun hundred million, this experiment is dynamic Object Science and Technology Ltd. (Jilin, China), all mouse keep the periodicity of illumination round the clock of 12h/12h, living environment during test It is maintained at temperature ± 23 ± 2 DEG C, humidity 55 ± 5%.Guarantee balanced standard diet and sufficient drinking public water supply.All realities Program is tested to be ratified by the zooscopy committee, Yanbian University.All experimental animals carry out humanistic care, and going forward side by side, all are exerted Power reduces experimental animal usage quantity and minimizes its pain.This experimental study meets ARRIVE guide (McGrat et Al., 2015).
The present invention uses acute and chronic alcoholic fatty liver model.Specifically, mouse C57BL/6 mouse in acute model Adaptation is randomly divided into three groups after a week: normal group, alcohol group, alcohol adds elm mushroom extract administration group (100mg/kg).Alcohol Group gives 31.5% alcoholic solution with the every 12h of administration group and carries out stomach-filling to mouse, altogether three times, while normal group equal heat quantity Smart solution carries out stomach-filling to maltose recklessly.Half an hour after administration group mouse alcohol stomach-filling, with the stomach-filling again of elm mushroom extract.Most Afterwards after an alcohol stomach-filling 4h, all mouse carry out heart puncturing extracting blood, anatomical isolation liver.It is stayed after blood 3000rpm centrifugation Taking serum, liver great Ye is immersed in room temperature in neutral formalin solution and retains, and liver leaflet is dispensed into 1.5ml centrifuge tube- 80 DEG C of keepings are in case he uses;C57BL/6 mouse adapts to be randomly divided into four groups after a week in Chronic Alcohol liver model: normal group, wine Smart group, alcohol adds elm mushroom that low dose group (50mg/kg) is administered, and alcohol adds elm mushroom that high dose group (100mg/kg) is administered.Just Normal group gives solid feed, and while administration group gives elm mushroom extract stomach-filling, normal group carries out physiological saline stomach-filling;Alcohol Group gives liquid alcohol feed for 5 days after giving liquid control feed, and the concentration of alcohol feed is gradually increased to 5%, 1% by 1% Alcohol feed to 4% each concentration is given two days, persistently gives 5% liquid alcohol feed later 28 days;Administration group mouse Feed mode is given with alcohol group, carries out elm mushroom extract (50 or 100mg/kg) while giving 5% liquid alcohol feed Stomach-filling, administration time have altogether 28 days.It is administered after four weeks and heart puncturing extracting blood, anatomical isolation liver is carried out to all mouse.Blood Serum is left and taken after 3000rpm centrifugation, liver great Ye is immersed in room temperature in neutral formalin solution and retains, and liver leaflet is dispensed into - 80 DEG C of keepings in 1.5mL centrifuge tube are in case he uses.
It is found by staining pathologic section, two kinds of models successfully cause the steatosis of mouse liver.Mouse elm is yellow The intake of mushroom extract has reversed the accumulation of liver fat caused by alcohol and the infiltration of inflammatory cell, and shows certain journey The dose dependent of degree.The overexpression of SIRT1 and AMPK α can promote the decomposition of fat.Alcohol group mouse IHC coloration result is aobvious Show, the dyeing of SIRT1 and AMPK α is shallower compared with normal group, illustrates the table of two kinds of albumen of SIRT1 and AMPK α in alcohol group Up to being suppressed;SIRT1 and AMPK α coloration result is obviously than alcohol group depth in the elm mushroom extract administration group, and has Dose dependent.Srebp1 is Fatty synthesis GAP-associated protein GAP, and the intake of alcohol can cause Srebp1 expression to increase.To acute and chronic Alcohol-induced liver injury model in mice Srebp1 ImmunohistochemistryResults Results can be seen that in alcohol group, and more normal group of the dyeing of Srebp1 It is obvious to deepen;The dyeing of elm mushroom extract administration group Srebp1 then obviously shoals compared with alcohol group, illustrates Srebp1 in elm Decline is expressed in yellow mushroom extract administration group.P2X7R plays a significant role in inflammation adjusting, the immunohistochemical staining of P2X7R Obviously relatively normal group is deep for the dyeing of P2X7R in alcohol group as the result is shown, illustrates the expression of the P2X7R in mouse liver in alcohol group Increase;Elm mushroom extract administration group, compared with model group, dyeing is shallower for the expression of P2X7R, and it is more to illustrate that the expression of P2X7R has Decline.Therefore elm mushroom extract inhibit alcoholic fatty liver lipopexia may with have activated SIRT1-AMPK signal path It is related, and inhibition of inflammation may be by lowering the expression of P2X7R, so that the release for reducing proinflammatory factor is related.
In HE dyeing of the invention, hematoxylin eosin staining method (abbreviation HE decoration method), is that paraffin section is most common One of colouring method.Hematoxylin dye liquor is alkalinity, mainly makes endonuclear chromatin and intracytoplasmic nucleic acid in bluish violet;She Red is acid dyes, and the ingredient of cytoplasm and extracellular matrix is mainly made to dye red.Need before dyeing to paraffin section into Row dewaxing, after paraffin section dries piece then conventional dewaxing carries out haematoxylin dyeing, slice is used after uniformly catching color to water PBS solution carries out returning indigo plant, until blue is presented in liver section, carries out eosin stains after rinsing 1min with tap water, slice is soaked Enter and rinses out extra Yihong dyestuff in the dyestuff of Yihong after 2-3min with tap water.Slice is taken off after dyeing Water, concentration alcohol is successively dehydrated gradient concentration alcohol from low to high, and slice is put into 10min in dimethylbenzene after dehydration It carries out transparent, finally carries out mounting with neutral gum.
It is established in acute and chronic alcoholic mouse model and elm mushroom extract-treated in of the invention, in order to illustrate elm Yellow mushroom extract establishes acute and chronic mouse alcoholic fatty liver model (Fig. 1) to the curative effect of alcoholic liver disease respectively.Fig. 1 Indicate acute and chronic alcoholic mouse model and elm mushroom extract-treated method, wherein Figure 1A is acute alcohol mouse rouge Fat liver modeling schematic diagram;Figure 1B is Chronic Alcohol mouse fatty liver modeling schematic diagram.
In the present invention, elm mushroom extract is as follows to the effect of alcohol-induced acute hepatic injury:
Acute alcohol-induced hepatic injury generally will appear the raising of transaminase, and Fig. 2A is in acute alcoholic liver disease mice serum ALT and AST content detection result column diagram, the results show that alcohol group serum alt and the AST significant raising compared with normal group (###P < 0.001);ALT, which is compared with the content of AST compared with model group, in administration group mice serum is declined (#P < 0.05). In addition, the measurement result (Fig. 2 B) to TG content in Models of Acute Alcoholic Liver Injury mice serum and liver shows alcohol group TG content is even in mice serum and liver is significantly higher than normal group (###P < 0.001), TG in administration group mice serum and liver Content be then significantly lower than alcohol group (* * * P < 0.001, * * * P < 0.01), illustrate that acute alcohol intakes cause mouse liver Damage, leads to the raising of ALT and AST, and can be visual and clear in HE and oil red O stain result see, acute alcohol stomach-filling Afterwards, there is apparent fat vacuole not of uniform size in alcohol group mouse liver, and oil red O stain is obviously deepened;Elm mushroom extract Then have no fat vacuole in administration group liver, oil red O stain result is close to normal group (Fig. 2 C and Fig. 2 D), this more intuitive theory Bright, elm mushroom extract can significantly inhibit the lipopexia phenomenon of acute alcoholic mouse liver injury process.Alcohol group is small In mouse liver Masson coloration result, the dyeing of alcohol group blue collagenous fibres does not increase significantly compared with normal group, perhaps Be since the acute alcohol model modeling time is shorter, though liver, which is had damage also, does not occur liver fibrosis (Fig. 2 E).
Fig. 2 indicates influence of the elm mushroom extract to acute alcohol model mice liver organization morphology and biochemical indicator. Transaminase content detection result in Fig. 2A acute alcohol model mice serum;Fig. 2 B. acute alcohol model mice serum and liver Middle content of triglyceride testing result;Fig. 2 C. acute alcohol model mice liver HE coloration result;Fig. 2 D. acute alcohol model Mouse liver oil red O stain result;Fig. 2 E is acute alcohol model mice liver Masson coloration result.### indicate with it is normal Group compare P < 0.001, * * * indicate with alcohol group compared with P < 0.001, * * indicate with alcohol group compared with P < 0.01, * expression and Alcohol group compares P < 0.05.
In the present invention, influence of the elm mushroom extract to chmice acute alcoholic liver lipopexia is as follows: SIRT1 is in rouge It plays an important role in the synthesis of fat, SREBP1 has regulating and controlling effect to lipolysis, carries out to acute alcoholic mouse model The expression of immunohistochemical experiment observation SIRT1, SREBP1, AMPK.SIRT1, AMPK α coloration result more normally organize shallowly, Illustrate in acute mouse liver injury model, the expression of both albumen is reduced;In elm mushroom extract administration group, two kinds of albumen For immunohistochemical staining result close to normal group, i.e., the expression of two kinds albumen organizes no significant difference (Fig. 3 A and Fig. 3 B) with normal. The immunohistochemistry coloring of SREBP1 is obviously deeper than normal group in acute alcoholic mouse model, illustrates SREBP1 in alcohol group mouse It expresses and increases in liver;Elm mushroom extract administration group SREBP1 immunohistochemical staining is close to normal group (Fig. 3 C).P2x7R exists It is played an important role in Inflammatory Pathway.In P2x7R immunostaining results, P2x7R coloration result in acute alcohol mouse liver It is obviously deeper than normal group, illustrates that P2x7R is higher than normal group in the expression of alcohol group, i.e., in acute alcohol model, mouse occurs The overexpression of P2x7R;Elm mushroom extract administration group liver dyes the overexpression (figure for not occurring P2x7R then close to normal group 3D)。
Fig. 3 indicates that elm mushroom extract expresses fat metabolism in acute alcohol model mice liver and inflammation related proteins Influence, Fig. 3 A. acute alcohol model mice liver SIRT1 ImmunohistochemistryResults Results;Fig. 3 B. acute alcohol model mice liver AMPK alpha immunization group result;Fig. 3 C. acute alcohol model mice liver SREBP1 ImmunohistochemistryResults Results;Fig. 3 D. acute alcohol mould Type mouse liver P2x7R ImmunohistochemistryResults Results.
The elm mushroom extract is as follows to the effect of chronic alcoholic mouse liver injury, detects to Chronic Alcohol model mice The significant product of hepatic injury, the level of ALT and AST, as a result as shown in Figure 4 A, ALT and AST in Chronic Alcohol group mice serum Content compared with normal group, it is even apparent increase (###P < 0.001, P## < 0.01);The high low dosage administration of elm mushroom extract For group compared with alcohol group, serum alt level is decreased obviously (* * P < 0.01), and AST level is also declined (* P < in serum 0.05).And elm mushroom extract high dose group ALT and AST fall is greater than low dose group.
Fig. 4 B indicates the horizontal result of content detection of TG in mouse liver and serum.It can be seen that alcohol group serum and liver The level of dirty middle TG is all significantly higher than normal group, illustrates in chronic alcoholic mouse liver injury model, mouse liver has occurred Apparent lipopexia phenomenon.In elm mushroom extract administration group, TG content in elm mushroom extract low dose group mice serum With model group no significant difference, liver TG has certain decline (* P < 0.05);High dose serum and liver is administered in elm mushroom extract The content of dirty middle TG then has more apparent decline (* * P < 0.01, * * * P < 0.001) compared with model group.
