Embodiment 4
[0043] Example 4 In vitro hemostasis experiment
[0044] 1 Materials and methods
[0045] 1.1 Preparation of anticoagulant blood: take blood from rabbit ear vein, and mix it gently with 3.8% sodium citrate solution at a volume ratio of 9:1. Centrifuge the anticoagulated blood at 1000r / min for 10min to prepare platelet-rich plasma, and centrifuge at 3000r / min for 10min to prepare platelet-poor plasma.
[0046] 1.2 Preparation of sample solution
[0047] Prepare 2 mg / mL Chinese herbal medicine toothpaste sample solutions 1-3 in Examples 1-3, blank paste liquid, Yunnan Baiyao toothpaste liquid, and Liangmianzhen toothpaste liquid for nourishing gums and protecting teeth.
[0048] 1.3 Determination of plasma calcium coverage time (RT)
[0049] Mix 0.1mL normal saline and 0.1mL platelet-rich plasma in a centrifuge tube, add 0.1mL CaCl with a mass fraction of 0.2775% in a water bath at 37°C 2 Mix the solution and start timing, and stop timing when a white filament is produced. ...
Embodiment 5
[0066] The clinical hemostasis experiment of embodiment 5 mice
[0067] 2 Materials and methods
[0068] 2.1 The hemostasis clinical experiment used blank paste, Yunnan Baiyao toothpaste, Liangmianzhen toothpaste for nourishing gums and toothpaste with Chinese herbal medicine in Examples 1-3 as test samples.
[0069] 2.2 It is carried out by observing the hemostasis of local wound wounds in mice. Take 108 healthy Kunming mice, weighing 18-22 g, both male and female. After anesthetizing the mouse, use surgical scissors to cut off the left lobe of the liver with a length of about 0.5 cm, a width of about 0.5 cm, and a height of about 0.5 cm. After wiping off the sprayed blood, immediately apply 0.5 g of the sample to be tested on the face , oppressed with 200g weight for 1min, remove the weight after 1min, observe the hemostatic effect, until no bleeding. If bleeding still occurs, pressurize after applying the sample to be tested, observe once every 30s, and record the hemost...
Embodiment 6
[0073] Embodiment 6 in vitro antibacterial experiment
[0074] 3 Materials and methods
[0075] 3.1 Experimental bacteria: 2 common oral pathogenic bacteria were selected: Streptococcus mutans (25175), Porphyromonas gingivalis (33277), Guangdong Microbial Culture Collection Center. Medium: BHI liquid medium, CDC anaerobic agar medium.
[0076] 3.2 The MIC and MBC of the test samples against bacteria were determined by the double dilution method. Bacterial suspension preparation: Streptococcus mutans and Porphyromonas gingivalis were resuscitated for 48 hours, inoculated in BHI liquid medium, 37 ° C in 85% N2 , 10%H 2 , 5%CO 2 After culturing in an anaerobic incubator for 24 hours under certain conditions, the bacterial growth reached the logarithmic phase at this time. After the smear microscopic examination showed pure culture, the bacterial liquid was collected and the bacterial concentration was adjusted to 1.0×10 5 ~1.0×10 6 CFU / mL, spare.
