Abstract

The present invention relates to a preparation method of IgY for preventing and cure mouth disease, and a safe toothpaste containing the IgY.

Claims

1. A method of producing an egg yolk immunoglobulin (IgY) for the control and treatment of oral diseases, comprising the steps of:

(1) incubating a pathogenic bacteria by using a conventional practice to incubate major pathogenic bacteria regarding to dental caries, periodontitis and halitosis;

(2) producing an antigen complex by producing antigen complex from said pathogenic bacteria incubated in step (1);

(3) carrying out an injection by injecting said antigen complex to an egg-laying avian (such as hens, ducks, turkeys, etc.);

(4) obtaining an immunized egg by analyzing and picking immunized eggs laid by said immunized avian; and

(5) producing an egg yolk immunoglobulin by preparing said egg yolk immunoglobulin from egg yolk of said immunized eggs collected.

2. The method, as recited in claim 1, wherein in step (1) further comprises a step of selecting a procedure to incubate and obtain type C, D and G of Streptococcus mutans based on the pathogens arising dental caries.

3. The method, as recited in claim 1, wherein in step (1) further comprises a step of selecting a procedure to incubate and obtain Fusobacterium nucleatum, Porphyromonas gingivalis and Actinomyces viscosus based on the pathogens arising periodontitis and halitosis.

4. The method, as recited in claim 3, wherein in step (1) further comprises a step of selecting a procedure to incubate and obtain Actinobacillus actinomycetemcomitans, Capnocytophaga ochracea, Treponemas denricola and Bacteroides forsythus based on the pathogens arising periodontitis and halitosis.

5. The method, as recited in claims 1, 2, 3 or 4, wherein in step (2) further comprises the steps of:

(2.1) mixing of said incubated bacteria with a specific ratio;

(2.2) adding of Freund adjuvant with the ratio 1;

1;

(2.3) shattering and mixing of the mixture with a liquid mixer up to 10,000-30,000 rpm; and

(2.4) producing an antigen complex related to dental caries, periodontitis and halitosis separately and respectively.

6. The method, as recited in claims 1, 2, 3 or 4, wherein in step (5) comprises the steps of:

(5.1) extracting an egg yolk from said immunized eggs using “

egg yolk sieve”

, and mixing the extraction thoroughly;

(5.2) adding distilled water 4-6 times to the volume of the extraction;

(5.3) adjusting the pH of the mixture within 4.5-6.5;

(5.4) adding 2% Sodium alginate and making its concentration in the mixture within 1.0%-2.0%, and stirring to precipitation;

(5.5) adding 2% CaCl₂ and making its concentration in the mixture within 0.5%-1.0%, and stirring thoroughly;

(5.6) positioning the mixture in 2-6°

C. for 8-12 hours and siphoning the supernatant;

(5.7) conducting the centrifugation of the supernatant in step (6) for 20 minutes at 8,000-12,000 rpm and taking the supernatant;

(5.8) conducting ultra filtration for the supernatant in step (7), and conducting sterilization with 0.22 μ

m membrane filter; and

(5.9) freeze drying and obtaining an IgY extract.

7. A toothpaste using said immunoglobulin (IgY) produced in claim 1 as one of its raw materials, comprising a paste containing 0.01-10.0% of said immunoglobulin.

8. The toothpaste, as recited in claim 7, wherein said immunoglobulin used can be produced by the method as recited in claims 2, 3 or 4, or by the method as recited in claims 1, 5 or 6, or by a combination of said immunoglobulin in claims 1-6.

9. The toothpaste, as recited in claim 7, wherein said paste comprises the ingredients consisting of:

(1) 0.3-5.0% foaming agent;

(2) 0.2-2.0% Sodium alginate;

(3) 0.5-5.0% carboxymethylcellulose sodium;

(4) 0.12-20.0% glycerol;

(5) 1.0-20.0% sorbitol;

(6) 0.12-0.5% aspartame; and

(7) an appropriate ratio of flavorings.

10. The toothpaste, as recited in claim 9, wherein said foaming agent does not denature protein and said foaming agent can be Hydrogenated Castor Oil Polyoxyethylene Ether, Sodium N-lauroylamide ethanoate or Sodium N-lauroyl sarcosinate, or a combination of said Hydrogenated Castor Oil Polyoxyethylene Ether, Sodium N-lauroylamide ethanoate or Sodium N-lauroyl sarcosinate.

11. The toothpaste, as recited in claim 10, further comprising an appropriate ratio of oral mucosa adsorbent, wherein said adsorbent can be 0.5-5.0% Caborpl.

12. The toothpaste, as recited in claim 11, wherein said flavorings consists of:

(1) 0.1-0.5% menthol essence;

(2) 0.1-0.5% orange essence;

(3) 0.1-0.5% peach essence; and

(4) 0.1-0.5% vanilla essence.

13. The toothpaste, as recited in claims 7, 8, 9, 10, 11 or 12, wherein said immunoglobulin is coated by water insoluble inert membrane which does not affect the activity of the immunoglobulin as micro-granulates, and is distributed thoroughly throughout said paste.

14. The toothpaste, as recited in claim 13, wherein said membrane can be a complex of polybenzylamide and polyethylene amide.

15. The toothpaste, as recited in claims 7, 8, 9, 10, 11 or 12, comprising a packing tube, wherein said packing tube comprises a sandwich layer having an inner-lumen and an outer-lumen, wherein said inner-lumen can be used to fill said paste with said immunoglobulin without foaming agent, said outer-lumen is filled with said paste that contain said foaming agent with no immunoglobulin, and vice versa.

16. The toothpaste, as recited in 7, 8, 9, 10, 11 or 12, comprising a packing tube, wherein said packing tube can be separated with a thin layer to form two partitions, that one of said partitions can be filled with said paste with said immunoglobulin containing no foaming agent, and that the other one partition is filled with said paste containing foaming agent without said immunoglobulin.
