The result of various researches mainly in search of 194 Shigella strains, isolated by the Health Research Centers(situated in Seoul city, Inchon city, Pusan city, Kyonggi-Do, Kangwon-Do, Chungchongnam and Buk-Do, Kyongsangnam and Buk-Do, Jollanam and Buk-Do, and Jaeju-Do) in addition to those clinical laboratories of all the general hospitals situated down twon Seoul, conducted during the month of Jan. through Dec. 85, through the reisolating-activity program following its transportation into the laboratory, particularly for a complete check on its correctiveness, are as follows: 1. Isolation processes were performed with the 194 strains obtained from each placeduring the period of investigation: 164 Strains(84.5%) of Sh. flexneri, B group; 6 Strains(3.1%) of Sh. boydii, C group; 24 Strains(12.3%) of Sh. sonnei, D group, which means there's quite a lot in B group while Sh. dysenteriae, A group was not isolated at all. 2. The isolation rate of the 164, B group for subserotype was 1b, 84(51.2%) the highest one, 2(1.2%) on 3a the lowest one, 4, on C group; In D group subserotype II showed 14(58.4%) more than subserotype I. 3. The biological data on sexuality regarding the isolation-strain showed traditional particularity. But the subserotype 1b in B group 2(2.4%) showed gas-growth from glucose. In subserotype 1a, the indole-growth was 88.9% on masculine which was considerably a good one. In the test of arginine dihydrolase subserotype I among D group showed 100% masculine rate. The subserotype 6 among B group showed 92.5% masculine. In the dissolution test of manitol, all subserotypes showed 100% maculine except subserotype 1b. In the dissolutioning test of rhamnose, the subserotype I among D group showed 100% masculine which is the unusual one. 4. Interms of the area among 13 districts examined, Kangwon-Do had 41(21.1%) which is the highest one on its ratio. 5. In terms of season on the strain isolation category, 44(22.7%) is the number isolated in April which is the highest one. 6. In terms of ages, the strain isolation ratio was notably high above the ages of 60 which was 34(17.5%). Next one was 29(14.9%) which was under the ages of 4. 7. In terms of sex, female was 113 or 58.2% while male was 74 or 38.2%, which means the female had more than the male. 8. The result of the resisting capability on the usage of 12 antibiotic medication was; 100% on chloramphenicol; 94.3% on tetracycline, 82.0% on streptomycin, 76.3% on carbenicillin, 74.7% on ampicillin, in regular order. The strain source bearing multimedication resisivity against the 5 antibiotic medication is as many as 117 or 60.3%. Of which 43.3% of 1b sub serotype, B group was the best one, and thus the resistivity against the antistrain medication seems the tendency is being changed. The summing up of the above result shows the total specific strains isolated in each branch in Korea is 194, of which the main type is Sh. flexneri 84.5%. The isolating rate is almost evenly spreading, although the Kangwon-Do showed the highest rate on the above data. It also shows female is higher than male on its statistics. The tendency on age category showed both on old and infancy generations high. However, the resistant capability against antibacteria medication or vaccine was still remaining on habitual one, particularly tending towards multimedication or vaccine trend.

본 연구에서는 잣나무 정유를 대상으로 GC-MS를 이용한 성분분석, 악취물질에 대한 소취효과 및 구강균에 대한 항균활성을 평가하였다. 잣나무 정유를 GC-MS를 이용하여 정성분석한 결과 ${\alpha}$-pinene이 19.38%로 가장 높은 구성을 차지하였고, 다음으로 3-carene (11.16%), camphene (10.57%), limonene (9.79%) 등의 terpene hydrocarbon류가 대부분을 차지하고 있었으며 이들 특유의 향취 조합으로 인해 잣나무 정유 고유의 향취를 나타내는 것으로 사료된다. 악취물질 4종에 대한 소취력 평가에서는 잣나무 정유를 주입한 1시간 후 75.17%의 ammonia 소취능을 나타내어 4종의 정유 중 가장 높은 활성을 나타냈다. Formaldehyde에 대한 소취력 평가에서는 편백나무와 소나무 정유가 61.67%로 가장 높은 활성을 보였고 잣나무 정유는 23.33%를 나타내었다. Trimethylamine에 대해서는 정유 주입 10분 후 편백나무, 전나무, 소나무 정유가 평균 6.70%로 낮은 활성을 나타낸 반면, 잣나무 정유를 주입함으로서 41.58%의 매우 높은 소취력을 나타내었다. Methylmercaptan에 대해서는 정유 주입 1시간 후 소나무(82.22%), 잣나무(70.56%), 전나무(62.22%), 편백나무(59.44%) 정유 순으로 소취력을 나타냈다. 구강균에 대한 정유 별 항균력 평가에서는 잣나무 정유($2.90{\pm}0.15mm$)는 L. paracasei에 대하여 전나무($1.83{\pm}0.18mm$)와 소나무($1.54{\pm}0.09mm$) 정유보다 강한 항균력을 나타내었으며, S. aureus에 대한 잣나무 정유($2.86{\pm}0.08mm$)의 항균활성 또한 전나무($1.15{\pm}0.20mm$)와 소나무($1.85{\pm}0.08mm$) 정유 보다 높게 나타났다. 특히 S. sobrinus에 대한 항균활성은 편백나무($1.42{\pm}0.01mm$)와 잣나무($1.40{\pm}0.01mm$) 정유를 처리함으로써 강하게 나타났으며 S. mutans에 대한 항균력은 편백나무>전나무>잣나무>소나무 정유 순으로 활성이 나타났다. E. faecalis에 대해서는 소나무($0.79{\pm}0.05mm$)정유만 항균활성을 나타내었다. 이상의 결과로 천연물 유래 잣나무 정유는 악취물질에 대한 소취효과 및 구강균에 대한 항균활성을 가지고 있다는 것으로 판단되며, 이를 활용한 구강탈취제, 구강청결제 등의 개발이 가능할 것으로 사료된다.
