(Preparation of chicken blood wisteria extract)
Chicken blood wisteria extract was prepared by adding 200 g (20% w / v) chicken blood wisteria to 1 liter of water and heating at 95 ° C for 3 hours to obtain chicken blood wisteria 20% extract, which was diluted appropriately with PBS. The following experiment was conducted.
Chicken blood wisteria used a dried stem of dense flower beans Spatholobus suberectus DUNN for the experiment.

(実施例1:Porphyromonas gingivalis ATCC 33277株(PG)感染マウス歯槽骨吸収モデルにおける鶏血藤の骨吸収抑制効果)
6週齢のC57BL/6マウス72匹を、24匹ずつ非感染コントロール群、PG感染コントロール群およびPG感染+鶏血藤投与(実験群)の3群に分け、それぞれにサルファメトキサゾールおよびトリメトプリムを含む飲料水を1週間投与し、口腔常在菌を除菌した。体内の抗菌薬を排出させるため3日間イオン交換水で飼育後、1週間に3回、1回につき約1×109個のPG菌体を含む2.5%カルボキシメチルセルロース溶液0.1mlを、PG感染コントロール群ならびに実験群に接種した。菌接種の完了と同時に、実験群には8%鶏血藤水抽出液を飲料水として供与し、その他はイオン交換水を飲料水とした。
感染終了後から1週間ごとに6週間にわたり各群から4匹ずつ抽出・屠殺し、右側頭部について当該骨格標本を作製し、上顎歯槽骨の吸収量を実体顕微鏡観察下で行った。左側頭部はギ酸ホルマリンで脱灰後、病理標本を作製し、ヘマトキシリン-エオシン染色あるいは酒石酸抵抗性酸性フォスファターゼ(TRAP)染色を行い、炎症の状態や破骨細胞の出現について検討した。
(Example 1: Porphyromonas gingivalis ATCC 33277 strain (PG) infected mouse alveolar bone resorption model in chicken blood rat bone resorption inhibitory effect)
72 6-week-old C57BL / 6 mice were divided into 3 groups: 24 non-infected control group, PG infection control group, and PG infection + chicken blood rat administration (experimental group), respectively, sulfamethoxazole and trimethoprim Was administered for 1 week to sterilize oral resident bacteria. PG infection control with 2.5 ml carboxymethylcellulose solution containing approximately 1 × 10 9 PG cells, 3 times a week after breeding with ion-exchanged water for 3 days to drain antibacterial agents in the body Groups and experimental groups were inoculated. Simultaneously with the completion of the inoculation, 8% chicken blood water extract was provided as drinking water to the experimental group, and ion exchange water was used as drinking water for the others.
Four animals from each group were extracted and killed every week for 6 weeks after the end of infection, the skeletal specimen was prepared for the right temporal region, and the amount of maxillary alveolar bone resorption was measured under a stereoscopic microscope. The left temporal region was decalcified with formalin formate, pathological specimens were prepared, and hematoxylin-eosin staining or tartrate-resistant acid phosphatase (TRAP) staining was performed to examine the state of inflammation and the appearance of osteoclasts.

FIG. 4 is a TRAP-stained image of mouse periodontal tissue.

図1の結果から、PG感染コントロール群では、非感染コントロール群と比べて経時的に骨の吸収量が増加し、その傾向は実験終了まで継続した。実験群では、骨吸収が非感染コントロール群と同程度まで抑制されたことから、鶏血藤の投与がPG感染による歯槽骨吸収の抑制に有効であることが示された。
また、図2の結果から、第1臼歯近心根から第3臼歯の遠心根を囲む歯槽骨面に認められた破骨細胞(osteoclast)は、PG感染コントロール群に明らかに多く、また実験経過に伴いその数は増加傾向を示したが、実験群は非感染コントロール群と相違はみられなかった。
一方、図4に示す病理標本において、非感染コントロール群、PG感染コントロール群及び実験群のいずれにも臼歯部歯間乳頭の粘膜上皮内と上皮直下にごく僅かの炎症細胞浸潤(好中球とリンパ球)が散見された。しかし、PG感染コントロール群では、非感染コントロール群に比べ歯槽骨面に吸収窩が多く認められ、実験期間の経過に伴い骨量の減少が観察された。実験群の歯槽骨には著しい変化はなく、非感染コントロール群ほぼ同様の所見であった。
From the results shown in FIG. 1, the bone resorption amount increased with time in the PG-infected control group compared to the non-infected control group, and this tendency continued until the end of the experiment. In the experimental group, bone resorption was suppressed to the same extent as in the non-infected control group, indicating that administration of chicken blood was effective in suppressing alveolar bone resorption caused by PG infection.
In addition, the results of Fig. 2 clearly show that osteoclasts (osteoclast) found in the alveolar bone surface surrounding the distal root of the third molar from the first mesial root to the third molar are more numerous in the PG-infected control group. The numbers showed an increasing trend, but the experimental group was not different from the non-infected control group.
On the other hand, in the pathological specimen shown in FIG. 4, in the non-infected control group, the PG infection control group, and the experimental group, very few inflammatory cell infiltrates (neutrophils and neutrophils) exist in the mucosal epithelium of the interdental papilla and directly under the epithelium. Lymphocytes) were found occasionally. However, in the PG-infected control group, more resorption pits were observed on the alveolar bone surface than in the non-infected control group, and a decrease in bone mass was observed as the experimental period progressed. There was no significant change in the alveolar bone of the experimental group, and the findings were similar to the non-infected control group.

(実施例2:PGに対する鶏血藤の抗菌効果)
0.2%、2%もしくは8%鶏血藤抽出液またはPBSの5mlに、OD600=1に調整したPGのPBS懸濁液の0.05mlを加え、0分、1分、15分または60分放置した。その後、サンプルを10倍希釈し、含まれる生菌数を培養法で計測した。培養は37℃嫌気条件(15%CO2、15%H2、70%N2)下で5日間行なった。結果を図5に示す。
図5の結果から、鶏血藤抽出液にPGを混合し60分間ベンチトップで放置すると、鶏血藤を加えないコントロール対して、鶏血藤0.2%濃度で約55%、2%濃度で約15%、8%濃度で約0.1%のレベルまで生菌数の減少が検出されたことから、鶏血藤は、濃度並びに時間依存的に、PGに対して抗菌効果を示すことが明らかとなった。
(Example 2: Antibacterial effect of chicken blood on PG)
Add 0.05 ml of PBS suspension of PG adjusted to OD 600 = 1 to 5 ml of 0.2%, 2% or 8% chicken blood wisteria extract or PBS and leave for 0 min, 1 min, 15 min or 60 min did. Then, the sample was diluted 10 times, and the number of viable bacteria contained was measured by a culture method. Culturing was carried out for 5 days under anaerobic conditions at 37 ° C. (15% CO 2 , 15% H 2 , 70% N 2 ). The results are shown in FIG.
From the results shown in FIG. 5, when PG was mixed with chicken blood rat extract and left on the bench top for 60 minutes, the control without adding chicken blood was about 55% for chicken blood and about 2% for 2%. A decrease in the number of viable bacteria was detected up to a level of about 0.1% at 15% and 8% concentrations, and it became clear that chicken blood rat showed an antibacterial effect on PG depending on the concentration and time. It was.

(実施例3:鶏血藤の破骨細胞の分化抑制効果)
骨髄由来の単球・マクロファージ等の破骨細胞の前駆細胞はMacrophage-Colony Stimulating Factor(M-CSF)の存在下でReceptor activator of NF-κB ligand (RANKL)の刺激により破骨細胞に分化することが知られている。マウス骨髄細胞も、M-CSF添加培地でRANKLのドナーであるMC3T3-G2/PA6細胞と共培養することで破骨細胞に分化する。そこで、破骨細胞の分化過程における鶏血藤の影響を検討する目的でマウス破骨細胞形成系に各種濃度の鶏血藤抽出液を添加し、破骨細胞の形成誘導に対する鶏血藤の影響を検討した。
(Example 3: Effect of inhibiting osteoclast differentiation of chicken blood rat)
Bone marrow-derived monocytes / macrophages and other osteoclast progenitors are differentiated into osteoclasts in the presence of Macrophage-Colony Stimulating Factor (M-CSF) upon stimulation with the receptor activator of NF-κB ligand (RANKL). It has been known. Mouse bone marrow cells also differentiate into osteoclasts by co-culturing with MC3T3-G2 / PA6 cells, which are donors of RANKL, in a medium supplemented with M-CSF. Therefore, in order to investigate the influence of chicken blood on the osteoclast differentiation process, various concentrations of chicken blood extract were added to the mouse osteoclast-forming system, and the influence of chicken blood on the induction of osteoclast formation.

C57BL/6マウス大腿骨より採取した骨髄細胞と破骨細胞分化支持能を持つMC3T3-G2/PA6細胞を各種濃度の鶏血藤抽出液を含むビタミンD3およびデキサメサゾンを添加した10%仔牛血清添加α-Minimum essential medium(α-MEM)で7日間培養した。培養終了後、サンプルを破骨細胞マーカーである酒石酸抵抗性酸性フォスファターゼ(TRAP)で染色し、TRAP陽性で3核以上の細胞を成熟破骨細胞としてカウントし、鶏血藤添加しなかったコントロール群と各種濃度の鶏血藤を加えた実験群に観察された成熟破骨細胞数をstudent-t検定で比較した。 結果を図6に示す。
図6の結果から、培地中に鶏血藤抽出液を添加しなかったコントロール群に比べ、鶏血藤抽出液0.1%および0.01%添加群では破骨細胞数がそれぞれ約100%および50%に減少し(p<0.01)、有意な発育抑制が検出された。以上の結果は、鶏血藤抽出液は、M-CSFとRANKL依存的な骨髄細胞から破骨細胞への分化を阻害することを示している。なお、前記鶏血藤抽出液のパーセントは、培地中の鶏血藤濃度である。
Bone marrow cells collected from C57BL / 6 mouse femur and MC3T3-G2 / PA6 cells with osteoclast differentiation supporting ability supplemented with 10% calf serum containing vitamin D3 and dexamethasone containing various concentrations of chicken blood -Cultured for 7 days in Minimum essential medium (α-MEM). After completion of the culture, the sample was stained with tartrate-resistant acid phosphatase (TRAP), an osteoclast marker, TRAP-positive cells with 3 or more nuclei were counted as mature osteoclasts, and the control group was not added with chicken blood. The number of mature osteoclasts observed in the experimental groups with various concentrations of chicken blood was added by the student-t test. The results are shown in FIG.
From the results shown in FIG. 6, the number of osteoclasts was increased to about 100% and 50% in the group with 0.1% and 0.01% chicken blood extract compared to the control group to which no chicken blood extract was added to the medium, respectively. Decreased (p <0.01) and significant growth inhibition was detected. These results indicate that chicken blood rat extract inhibits differentiation from bone marrow cells to osteoclasts dependent on M-CSF and RANKL. In addition, the percentage of the said chicken blood rat extract is the chicken blood rat density | concentration in a culture medium.

(実施例4:RANKLの破骨細胞延命作用に対する鶏血藤の抑制効果)
Receptor activator of NF-κB ligand (RANKL)やMacrophage-Colony Stimulating Factor(M-CSF)は破骨細胞の分化に必須であり、また破骨細胞の生存を延長することが知られている。破骨細胞をRANKL添加培地で培養すると、未添加培地と比べた場合に比べその寿命が大幅に延長する。一方、RANKL未添加培地中の破骨細胞は急速に死滅する。そこで、RANKLによる成熟破骨細胞生存に対する鶏血藤の影響を検討した。
(Example 4: Inhibitory effect of chicken blood on the osteoclast life-prolonging effect of RANKL)
Receptor activator of NF-κB ligand (RANKL) and Macrophage-Colony Stimulating Factor (M-CSF) are essential for osteoclast differentiation and are known to prolong osteoclast survival. When osteoclasts are cultured in a medium supplemented with RANKL, their lifespan is greatly extended compared to a medium supplemented with no RANKL. On the other hand, osteoclasts in the medium without RANKL die rapidly. Therefore, the effect of chicken blood on the survival of mature osteoclasts by RANKL was examined.

C57BL/6マウス骨髄細胞とMC3T3-G2/PA6細胞をビタミンD3(1x10-8M)、プロスタグランジンE2(1x10-7M)および10%仔牛血清を含むα-Mimimum Essential Medium (MEM)で培養、形成された破骨細胞を分離した。
その後、破骨細胞を、次の3種類の培地で48時間培養した。
1.RANKL未添加α-MEM培地
2.RANKL(200μg/ml)、M-CSF(100μg/ml)添加α-MEM
3.RANKL(200μg/ml)、M-CSF(100μg/ml)および各種濃度の鶏血藤抽出液の添加α-MEM
培養後、成熟破骨細胞マーカーである酒石酸抵抗性酸性フォスファターゼ(TRAP)の染色を行った。TRAP陽性で3核以上の細胞を生存破骨細胞としてカウントし、観察された破骨細胞数をstudent-t検定で比較した。結果を図7に示す。
図7の結果から、鶏血藤抽出液を最終濃度0.1%、0.01%、および0.001%濃度で培地に添加した実験群では、RANKL添加により寿命が延長した陽性コントロール群に比べ生存する破骨細胞数がそれぞれ約30%、40%および80%と有意に減少した(p<0.01)。これは、培養過程で細胞が死滅したことを示すものである。
C57BL / 6 mouse bone marrow cells and MC3T3-G2 / PA6 cells vitamin D3 (1x10 -8 M), prostaglandin E2 (1x10 - 7M) and cultured in α-Mimimum Essential Medium (MEM) containing 10% calf serum, The formed osteoclasts were isolated.
Thereafter, osteoclasts were cultured in the following three media for 48 hours.
1. 1. RANKL-free α-MEM medium Α-MEM with RANKL (200μg / ml) and M-CSF (100μg / ml)
3. Addition of RANKL (200 μg / ml), M-CSF (100 μg / ml) and various concentrations of chicken blood wisteria extract α-MEM
After the culture, staining with tartrate-resistant acid phosphatase (TRAP), which is a mature osteoclast marker, was performed. TRAP-positive cells with 3 or more nuclei were counted as viable osteoclasts, and the number of observed osteoclasts was compared by student-t test. The results are shown in FIG.
From the results shown in FIG. 7, the experimental group in which chicken blood wisteria extract was added to the medium at final concentrations of 0.1%, 0.01%, and 0.001% concentrations survived compared to the positive control group in which the life span was extended by the addition of RANKL. The number of bone cells was significantly reduced to about 30%, 40% and 80%, respectively (p <0.01). This indicates that cells were killed during the culture process.
