Moisture absorption wicking surface sprays Chinese medicine antibacterial anti-inflammatory liquid prepared by embodiment 3, fountain height 10-20mL/m2。
1 test example of test example, 2 bacteriostatic experiment
1, for trying strain：Escherichia coli, staphylococcus aureus, Escherichia coli, bacillus subtilis, Candida albicans Bacterium；
2, for reagent product：The ethanol solution of graphene oxide-copper silver nanoparticle compound prepared by embodiment 1, embodiment 3 are made Standby Chinese medicine antibacterial anti-inflammatory liquid；
3, the preparation of culture medium：
LB liquid medium：Peptone 10g, yeast powder 5g, NaCl 10g add pure water to 1000ml, adjust pH value and reach 7.0；
LB solid mediums：Beef extract 3g, peptone 10g, yeast powder 5g, NaC1 10g, 15~20g of agar, add pure Water adjusts pH value up to 7.0 autoclave sterilizations, makes culture medium to 1000mL.
Culture dish and test tube are wrapped with newspaper, solid medium is prepared according to formula, high pressure is then put into together and goes out It sterilizes in bacterium pot.Tablet is made in the solid medium culture dish of falling people, liquid aglucon pours into test tube.
4, the preparation of bacteria suspension：
Escherichia coli, staphylococcus aureus, Escherichia coli, bacillus subtilis, white are read with tablet setting-out method Pearl bacterium is inoculated in respectively on LB solid mediums, is sealed with sealed membrane, is set for 37 DEG C and is cultivated reactivated bacteria for 24 hours in biochemical cultivation case, After activation, with the bacterium of the same bacterium colony of oese picking, it is inoculated in the test tube equipped with LB liquid medium, is subsequently placed in gas bath 37 DEG C of culture 48h are used as experimental strain in constant-temperature table.
5, the experiment of drug fungistatic effect：
After experimental strain culture is good, start bacteriostatic experiment on superclean bench.Experimental strain is shaken up, liquid-transfering gun is used 50 μ L bacteria suspensions are pipetted on the tablet made, tiling smoothens, 5 kinds of experimental bacterias, each applies 30 tablets, then will be sterilized Oxford cup is equidistantly placed on agar surface, quiet on super-clean bench to put 10min after all sequencing per 6, ware.It is sterilized with 1mL Liquid-transfering gun draws 200 μ L of target liquid, injects in the Oxford cup set, and 5 Oxford cups note people's same drugs, Ling Yiniu in every ware Tianjin cup injects the 200 μ L of bacterium ethyl alcohol that gone out and compares, and is then sealed with sealed membrane is careful.Each drug corresponds to each bacterium difference Tablet is made, totally 25 tablets do ethanol solution (n=25) antibacterial of graphene oxide-copper silver nanoparticle compound, use sterile alcohol For control group, same 25 tablets do Chinese medicine antibacterial anti-inflammatory liquid (n=25) antibacterial, are control group with sterile alcohol.Postposition In cultivating the bacterial growth situation observed afterwards for 24 hours in culture dish in 37 DEG C of biochemical cultivation cases, it is used in combination micrometer to correspond to measurement each The diameter and record of processing group and control group inhibition zone, effective to be denoted as "+", no effect is denoted as "-", presses down compared with the control group Bacterium effect.
Experimental result is shown in Table 1.
The fungistatic effect of 1 two kinds of liquids of table
By the above experimental result it is found that graphene oxide-copper silver nanoparticle compound has apparent antibacterial and bacteriostasis, but It is only obvious to the inhibiting effect of bacillus subtilis and Candida albicans, it is extracted by adding some other traditional Chinese medicinal components Object can enhance the fungistatic effect of graphene oxide-copper silver nanoparticle compound, and reach has apparent inhibition effect to five kinds of bacteriums Fruit, especially for the easy gram-positive cocci inhibition for causing warts it is also obvious that the stern of user therefore can be protected Portion's health.
2 rat contact dermatitis eczema of embodiment is tested
1, group is tested.Prepare 80 SPF grades of SD hyperlipemia rats and be randomly divided into 4 groups, every group 20, respectively Chinese medicine is anti- Bacterium anti-inflammatory liquid (1 group), cloudy scorching detergent group (2 groups), control group and normal group.
Modeling method：In addition to normal group, 1d removes abdomen (2cm to remaining each group rat with shaver before administration × 2cm) mouse hair, the then 50 μ L sensitization of DNCB acetone solns of even spread 7%；After for 24 hours again with 1% DNCB acetone solns 50 μ L reinforcing stimuluses；When modeling the 5th day, the mouse hair of rat back (cm of 2cm × 2) is removed, 1% DNCB acetone solns are used in combination Then 50 μ L sensitization repeat to be sensitized, 3 times altogether every 3d.Normal rats use the acetone soln without DNCB to be administered, remaining It operates identical.
2, experimental method.Since modeling the 9th day, normal group and control rats were coated with purified water, and 1 group of rat, which applies, implements Chinese medicine antibacterial anti-inflammatory liquid prepared by example 3,2 groups of cloudy scorching detergents in rat coating ground are early, middle and late daily to be respectively administered once, and are administered Dosage is 100 μ L, successive administration 10d.
3, skin allergy reaction scoring and skin turgor degree measure.Preceding and 10 d of administration are administered in rat after modeling Afterwards, EASI evaluation schemes are all made of and carry out skin allergy reaction assessment scoring：Serious redness simultaneously has the mossization papule person of festering, 4 points of note；Moderate is red and swollen, incrustation, without fester, mossization person, remember 3 points；There is redness but without papule person, remembers 2 points；Mild redness person, 1 point of note；Without apparent lesion person, 0 point is remembered.And after 10d is administered, is decocted with aseptic operation and decoct lower inflammation district skin and correspondence respectively Side healthy skin takes the skin of 1cm × cm with card punch respectively, claims quality with electronic analytical balance and records, with inflammation skin The difference of quality and healthy skin quality indicates skin turgor degree.
Experimental result is shown in Table 2.
2 each group rat allergic reaction of table scores and skin turgor degree result
Group n Allergic reaction scores Skin turgor degree/g
Normal group 20 0 0.012
Control group 20 3.5 0.207
1 group 20 1.2 0.097
2 groups 20 2.7 0.145
It can be seen from the above result that Chinese medicine antibacterial antiphlogistic liquid energy prepared by the present invention obviously treats dermatitis and eczema, effect is equal Better than cloudy scorching detergent.Therefore, Chinese medicine antibacterial antiphlogistic of the invention, which is applied in paper diaper, has very well treatment eczema Application prospect.
Those skilled in the art is not under conditions of departing from the spirit and scope of the present invention of claims determination, also Various modifications can be carried out to the above content.Therefore the scope of the present invention is not limited in above explanation, but by The range of claims determines.
