Benefits of technology

The present invention provides a herbal mixture extract of Pleurotus eryngii, Acanthopanacis Cortex, and Notoginseng Radix. This herbal mixture extract can be used as an active ingredient in a composition for prevention and treatment of periodontal disease. The technical effect of this invention is to provide a natural and effective solution for preventing and treating periodontal disease.

Problems solved by technology

As disease gets serious to spread deep into periodontal supporting apparatus, dental root and periodontal ligament attached on alveolar bone are destroyed, leading to the destruction of alveolar bone itself.
Particularly, oral bacteria form dental plaque due to poor oral hygiene, resulting in bleeding in gingiva and halitosis due to inflammation.
As periodontitis progresses, gingival bleeding can be triggered by even weak stimulus such as tooth-brushing and becomes swollen, and sometimes it progresses to acute inflammation carrying great pain.
As a result, alveolar bones are decreased in amount and further destroyed, leading to the loss of teeth.
Toxin of the proliferated anaerobic Gram (−) bacteria and other products thereby might directly destroy the tissues or stimulate immune system.
However, these surgical treatments are limited to the treatment of progressed diseases only, not effective for prevention of disease, and ask patients to visit a dental clinic necessarily.
Supplementary treatment such as administration of antibiotics and local slow-releasing agents has been performed with the fundamental treatment, but it has problems of side effects caused by medicine administered to whole body, which means untargeted areas are also affected, and generating periodontal disease bacteria having a resistance against antibiotics (in fact, periodontal disease bacteria showing antibiotics resistance have been isolated).
If epithelial tissue derived cells are involved, long epithelial attachment is generated, suggesting that regeneration of periodontal tissue is unsatisfactory.

Preparation of Herbal Extracts

[0042] Cultivated Pleurotus eryngii, Acanthopanacis Cortex and Notoginseng Radix were purchased from a wholesale dried medicinal herb store.

Alcohol Crude Extract of Herbal Mixture

[0043] Each medicinal herb was cut into 1˜2 cm fractions, which were washed with running water to eliminate impurities. The fractionated herbs were pulverized. Pleurotus eryngii, Acanthopanacis Cortex and Notoginseng Radix were mixed at the ratio of 4:1:5, resulting in a powder mixture. 200 g of the mixed powder was put in a 3 l flask. Heat extraction was performed using 2,000 ml of ethanol at 78.5° C. for 4 hours with stirring at reflux, which was repeated three times. The extracted solution was filtered and concentrated under reduced pressure under 40° C. by using vacuum rotary evaporator, resulting in herbal mixture extract.

Water Crude Extract of Herbal Mixture

[0044] Extraction was performed by the same manner as described in Example except that water was used as a e...

Increase of OPG (osteoprotegerin) Expression in Osteoblasts by Herbal Mixture Extract

[0047] Following experiments were performed to examine the effect of herbal mixture extract or each independent herb extract prepared in on the expression of osteoprotegerin in osteoblasts.

Osteoblast Selection and Cell Culture

[0048] The following three types of cells were used to investigate the effect of the herbal mixture extract or each independent herbal extract of the present invention on the proliferation of osteoblasts. A human osteosarcoma derived cell line MG-63 (ATCC No, CRL-1427) and a mouse muscle derived cell line C2C12 (ATCC No. CRL-1772) were distributed from American Type Culture Collection (ATCC, USA). The cells were cultured in DMEM (Gibco, BRL, USA) supplemented with 10% FBS (fetal bovine serum) in a 37° C. 5% CO2 incubator with 100% humidity.

[0049] As a primary culture cell, osteoclasts obtained from Sprague-Dawley rat calvaria (RCC) were used. Precisely, frontal bone and p...

Inhibition of Osteoclast Proliferation by Herbal Mixture Extract

[0053] To examine whether the herbal mixture extract of the present invention and each independent herbal extract could inhibit the formation of osteoclasts and reduce cellular activity, the present inventors performed following experiments.

Isolation of Osteoclast Precursor Cells and Differentiation of Osteoclast Precursor Cells into Mature Osteoclasts

[0054] To isolate mouse bone marrow cells, male mouse at 7-9 weeks old was sacrificed by kinked neck, then femur and tibia were extracted under aseptic condition. Soft tissue was eliminated and both ends of ilium were cut out. 1 ml of an enzyme solution containing 0.1% collagenase (Gibco), 0.05% trypsin and 0.5 mM EDTA (Gibco) was injected into one end of medullary cavity by using 26 G needle. Bone marrow was taken out, followed by stirring for 30 minutes. Bone marrow cells were recovered and pre-cultured for 24 hours in α-MEM (α-minimum essential medium) supplemented ...

Abstract

The present invention relates to a herbal mixture extract of Pleurotus eryngii, Acanthopanacis Cortex and Notoginseng Radix and a composition for prevention and treatment of periodontal disease containing the herbal mixture extract as an active ingredient, more precisely, a herbal mixture extract having activities of inhibiting the generation and activation of osteoclasts by enhancing the expression of osteoprotegerin (OPG) in osteoblasts, preventing alveolar bone from destruction by inhibiting the proliferation of osteoclasts and maintaining the growth of periodontal ligament cells and gingival fibroblasts, and a composition for prevention and treatment of periodontal disease containing the above mixture as an active ingredient.

Description

TECHNICAL FIELD [0001] The present invention relates to a herbal mixture extract of Pleurotus eryngii, Acanthopanacis Cortex and Notoginseng Radix and a composition for prevention and treatment of periodontal disease containing the herbal mixture extract as an active ingredient. BACKGROUND ART [0002] Periodontal tissue is composed of alveolar bone, gingiva and periodontal ligament. Gingiva is a part of dental supporting apparatus in oral cavity, from which disease such as gingivitis is set off. As disease gets serious to spread deep into periodontal supporting apparatus, dental root and periodontal ligament attached on alveolar bone are destroyed, leading to the destruction of alveolar bone itself. As a result, periodontitis is developed. [0003] Periodontal disease including gingivitis and periodontitis is characterized by inflammation in dental supporting apparatus caused by bacterial infection, which carries the symptoms of bleeding, periodontal pocket formation and alveolar bone ...
