Summary for Patent: 6,045,800

Title:	Composition for preventing or treating periodontal diseases comprising extract from Achyranthis radix or Ulmus cortex
Abstract:	The present invention provides a composition for preventing or treating periodontal diseases comprising an extract of Achyranthis radix, Ulmus cortex or a mixture thereof which inhibits the productions of superoxide, prostaglandin, and interleukin (IL-1.beta.) which are inducers for periodontal diseases and inhibits the enzyme activity of collagenase which decomposes collagen protein which is a substrate for the periodontal tissues, and at the same time promotes collagen protein synthesis, thereby treating periodontal diseases efficiently.

Assignee:	LG Chemical Ltd. (Seoul, KR)
Application Number:	09/031,063
Patent Claims:	1. A composition for treating or preventing periodontal diseases which comprises an amount of (i) a lower alkyl alcohol extract or aqueous extract of Achyranthis radix (ii) a lower alkyl alcohol extract or aqueous extract of Ulmus cortex or (iii) a mixture of said extracts effective to reduce a gingival index. 2. The composition according to claim 1, wherein the amount of the sole extract ranges from 0.001 to 5% by weight and the amount of the extract in the mixture ranges from 0.002 to 10% by weight based on the weight of the total composition. 3. The composition according to claim 2, wherein the composition is prepared in the form of dentifrice. 4. The composition according to claim 3, further comprising an abrasive selected from the group consisting of calcium monohydrogen phosphate, precipitated silica and calcium carbonate in an amount of 20 to 60% by weight based on the weight of the total composition. 5. The composition according to claim 3, further comprising fluoride compound selected from the group consisting of sodium fluoride and disodium fluorophosphate in an amount of 0.01 to 2.0% by weight based on the weight of the total composition. 6. The composition according to claim 2, wherein the composition is prepared in the form of ointment. 7. The composition according to claim 6, further comprising a surfactant, a solubilizing agent, a wetting agent, an active component delivery agent, a buffer, a sweetener, and a flavor, and a mixture thereof. 8. The composition according to claim 7, wherein the surfactant is polyoxyethylene-polyoxypropylene copolymer in an amount of 5 to 30% by weight based on the weight of the total composition. 9. The composition according to claim 7, wherein the solubilizing agent is a C.sub.1 to C.sub.4 lower alcohol selected from the group consisting of methanol, ethanol, isopropanol, and butanol in an amount of 1 to 20% by weight based on the weight of the total composition. 10. The composition according to claim 7, wherein the wetting agent is selected from the group consisting of glycerine, sorbitol solution, Polyethylene glycol 200, Polyethylene glycol 400, Polyethylene glycol 600, Polyethylene glycol 1000, propylene glycol, Poloxamer 407, Myverol 18-99, and a mixture thereof in an amount of 5 to 40% by weight based on the weight of the total composition. 11. The composition according to claim 7, wherein the active component delivery agent is gelatine, pectin or a mixture thereof in an amount of 1 to 30% by weight based on the weight of the total composition. 12. The composition according to claim 7, wherein the buffer is selected from the group consisting of sodium dihydrogen phosphate, disodium hydrogen phosphate, sodium phosphate, citric acid, sodium citrate, phosphoric acid, hydrochloride, sodium hydroxide, sodium pyrophosphate, pyrophosphate and a mixture thereof, and the pH of the composition is adjusted to 5 to 8. 13. The composition of claim 1, wherein said lower alkyl alcohol is selected from the group consisting of methanol, ethanol, propanol and butanol. 14. A composition for treating or preventing periodontal diseases which comprises an amount of (i) a lower alkyl alcohol extract or aqueous extract of Achyranthis radix, (ii) a lower alkyl alcohol extract or aqueous extract of Ulmus cortex or (iii) a mixture of said extracts effective to inhibit production of interleukin-1.beta., superoxide and prostaglandin E.sub.2 by mononuclear leukocytes. 15. The composition of claim 14, wherein said lower alkyl alcohol is selected from the group consisting of methanol, ethanol, propanol and butanol. 16. A composition for treating or preventing periodontal diseases which comprises an amount of (i) a lower alkyl alcohol extract or aqueous extract of Achyranthis radix, (ii) a lower alkyl alcohol extract or aqueous extract of Ulmus cortex or (iii) a mixture of said extracts effective to promote collagen synthesis by gingival fibroblasts and inhibit collagenase activity. 17. The composition of claim 16, wherein said lower alkyl alcohol is selected from the group consisting of methanol, ethanol, propanol and butanol.
