The most important object of periodontal treatment is the perfect regeneration of destructed periodontal tissue. The healing of periodontal lesion is affected by several cells & factors, which result in formation of long juntional epithelium, root resorption, bony ankylosis or connective tissue attachment. And ideal healing is enhanced by epithilial exclusion or periodontal ligament cell activation. In this investigation, I studied the effect of Zizyphus Fructus extract which enhances biologic activity& collagen synthesis, on the chemotaxis & cell nature. The cells were obtained from interdental area & middle third area of the freshly extracted teeth for the orthodontic purpose. And they were fully incubated in${\alpha}-MEM$ solution containing $100{\mu]g/ml$ penicillin & $100{\mu]g/ml$ streptomycin followed by 6 generation incubation. The test cells were collected by trypsin-EDTA & centrifuge in the fully incubated cells, counted by Hernacyotmeter, incbated $5{\times}10^5/ml$ cells for 24 hours, re-incubated 24 hours in media containing natural extract and photographed. The cells were incubated for 4 hours in 48 well microchemotaxis chamber bisecting upper & lower chamber by 8ug/m pore polycarbonate membrane coating 5mg/ml gelatin solution. The migrated cells in microscope were counted, which meaned cell chemotaxis activity. The study had shown that the morphology of cell was spindle-shaped as the control group, and the subextract test groups were not significantly different. In gingival fibroblasts, the chemotaxis effect of PDGF was statistically significant compared to control group. The Zizyphus Fructus extract was more or less enhanced chemotaxis effect and in $1{\mu}g/ml$ concentration the chemotaxis effect was slightly elevated compared with $10{\mu}g/ml$ concentration. But, among the subextracts, it was not significantly defferent. In PDL cells, the chemotaxis effect of PDGF in statistically significant, and the zizyphus Fructus extract had shown the enhanced effect. The effect was slightly higher in $1{\mu}g/ml$ concentration than 10g/ml concentration,and no significance among the subextracts.

Background: The purpose of this study was to analyze the applicability of dried jujube (Zizypui Fructus) distributed by size as a functional food material and herbal medicine by evaluating its physicochemical characteristics and betulinic acid content. Methods and Results: It was shown that the carbohydrate content of in jujube fruit significantly increased with fruit size; 81.42% for large, 79.83% for medium, and 76.39% for small. Similarly, the dilute ethanol extract content of each group was 72.48% (large), 69.56% (medium), and 64.16% (small). A free sugar analysis indicated that glucose, fructose and sucrose were found in quantitieds proportional to jujube fruit size, the total free sugar values were 68.85%, 63.93%, and 57.37% for large, medium, and small fruit sizes respectively. The betulinic acid content for large, medium, and small fruit was 0.50 mg/g, 0.54 mg/g, and 0.58 mg/g respectively, indicating that smaller jujube contained a higher amount of betulinic acid. Conclusions: It is considered that betulinic acid content could be used as a criteria for jujube fruit quality control.

장수상황버섯(Phellinus baumii) 균사체를 이용한 한약재의 고체발효를 통한 기능성 강화 한약재 생산을 목적으로, 항산화 활성 또는 혈류 개선활성이 우수하다고 알려진 36종의 한약재를 멸균 후, 장수상황버섯 균사체를 접종하여 고체발효 가능성을 검토하였다. $2^{\circ}C$, 상대습도 90% 배양기에서 20일간 발효시킨 결과, 감국, 대추, 백부자, 신이 및 황정을 제외한 31종에서 양호한 발효가 진행되었으며, 발효 가능여부는 한약재 식물체의 사용부위의 구조적 견고성, 영양조건 및 항진균 활성 등과 연관되리라 판단된다. 한약재의 고체발효 이후, 발효전과 비교하였을 때 평균 수분함량은 $30.84{\pm}15.67%$에서 $67.21{\pm}11.43%$로 2.2배 증대되었으며, 평균 메탄올 추출효율과 평균 pH는 $13.91{\pm}12.22%$ 및 $5.06{\pm}0.87$에서 각각 $11.16{\pm}7.06%$ 및 $4.83{\pm}0.73$ 다소 감소하는 경향을 나타내었다. 각각의 메탄올 추출물을 이용한 항혈전 활성 및 항산화 활성을 측정한 결과, 골쇄보, 천련자, 도엽, 와송의 경우에는 트롬빈 저해 활성이 각각 발효전에 비하여 31.38, 23.63, 22.57, 13.85% 증가되었으며, 원지, 현삼, 백지, 향부자, 골쇄보 및 육종용에서는 DPPH 소거능이 발효전에 비해 각각 58.9, 49.8, 48.1, 32.8, 24.1, 20.7% 증가되어 장수상황버섯 균사체 발효 한약재의 긍정적 생리활성 증가를 확인하였다. 본 연구결과는 상황버섯 균사체를 이용한 한약재의 고체발효를 통해, 특정 기능성의 강화 원재료를 생산할 수 있으며, 골쇄보의 경우와 같이 항혈전 활성 및 항산화 활성이 동시에 증대된 한약재 생산이 가능함을 제시하고 있다.
