  • This study was carried out to investigate quality characteristics of chopped garlic stored at various temperature. Chopped garlic was stored at room temp.($25^{\circ}C$), refrigerator temp.($5^{\circ}C$) and frozen temp. ($-18^{\circ}C$) for 1, 2, 4, 8, 24, 48, 72 hours(room temp.) and 1, 3, 5, 7, 10, 15, 20, 30 days(refrigerator temp. and frozen temp.), respectively. Brown color, Hunter color value, vitamine C contents and flavor patterns by electronic noes of chopped garlic were measured. Fresh chopped garlic was used as control and garlic powder by hot air drying was used for comparisons. Brown color of chopped garlic increased with increasing storage time, and the intensity of that was reduced as following order such as chopped garlic stored at room temp., refrigerator temp. and frozen temp. Brown color of garlic powder was most dark amomg all the samples. The results of Hunter color value was consistent with then of brown color in chopped garlic, whereas those of garlic powder showed relatively low browning. Above results might be caused by the difference of measurement as only surface color was measured in Hunter color value unlike brown color. Vitamine C contents of chopped garlic decreased with increasing storage time, and in particular those stored at room temp. decreased markedly as retention of those stored at room temp. was 60% of control after 1 day storage. Vitamine C retention of chopped garlic stored at refrigerator temp. was 78% of control after 10 day storage and that stored at frozen temp. was 86% of control after 30 day storage. At room temp., flavor pattern by electronic nose showed a difference between chopped garlic stored for 1hour and control, and showed occurrence of off odor after 1 day storage. Flavor pattern of garlic powder by electronic nose showed a mild flavor. Flavor patterns of chopped garlic stored at refrigerator temp. were similiar until 10 day storage, whereas those showed occurrence of volitile components after 15 day storage. Flavor patterns of chopped garlic stored at frozen temp. were similiar after 30 day storage, and especially those after 3 day storage were almost the same as control. Therefore it is desirable to store chopped garlic within 1 day at room temp. and within 10 days at refrigerator temp. And it is most desirable to store chopped garlic at frozen temp. as retention of quality characteristics was superior than other storage temp.

  • The considerable researches have been done on the change,1 associated with age in the blood picture of domestic animals, but a survey has not been of the blood picture in Thoroughbred fears in Korea. Therefore, the purpose of this study is to outline the range of values in clinically not\\\\`- mal Thoroughbred foals. Some blood chemical parameters from 3 days to 8 weeks of age were exam-ined to obtain normal values in Thoroughbred foal7. Blood samples were obtained from the jugular vein in 11 Thoroughbred foals and collected at 3 days, and at 1,2,4 and 8 weeks of age, respectively. The results obtained ill this study were summarized as follows: The packed cell volume (PCV) at 4 weeks of age was significantly lower than that at 3 days of age (P<0.01) and that al 2 and 8 weeks of age were straightly lower than that at 3 days of age (P<0.05). The total protein (TP) at 8 weeks of age was higher than that at 3 days, 1 and 2 weeks of age (P<0.05). The activity of aspartate ami-notransferase (AST) at 2,4 and 8 weeks of age were significantly higher than that at 3 days of age (P<0.01). The total bilirnbin showed a tendency to decrease gradually according to the weeks and that at 2,4 and 8 weeks of age were significantly lower than that at 3 days of age (P<0.01). The BUN at 1 and 8 weeks of ago were lower than that at 3 days of age (P<0.05). The concentration of Ca at 1 week of alee was higher than that at 3 days of age (P<0.05). The vitamin A and vitamin E showed a tendency to decrease gradually from 3 days to 4 weeks of age and increased slightly at 8 weeks of age.

  • Fruits of Arctium lappa L. (Compositae), which has been used as the antiinflammatory, detoxifying and diuretic agents in the folk remedies, was examined on the in vitro oxidation of human low density lipoprotein (LDL). Several lines of evidence indicate that oxidized LDL (Ox-LDL) may promote atherogenesis. Hence. The role of antioxidants in the prevention of LDL oxidation needs to be determined. The activity of fractions of Arctii Fructus treated with oxidized LDL which was incubated with $16\;{\mu}M$ of $Cu^{2+}$ for metal catalyzed oxidation was investigated. The BuOH fraction (4\;ppm) inhibited the oxidative modification of LDL as evidenced by a decrease in the lipid peroxide content (thiobarbituric acid reacting substances activity), the negative charge of LDL (electrophoretic mobility) and increase of the vitamine E content.

  • Recently many researches on plaque removal effect and therapeutic effect of toothpaste containing natural medicines are being studied in early periodontal diseases. The purpose of this study is to examine the clinical and microbiological effect of toothpaste containing natural medicines such as camomile, rhatany, myrrh,sage oil, glycyrrhetinic acid and vitamin E. Sixty three subjects with gingivitis were divided into an experimental group which performed normal oral hygiene procedure with toothpaste containing natural medicines and vitamine E and a control group which also performed normal oral hygiene procedure with Syrinmed? toothpaste without containing herbal extracts and vitamine E. At the baseline, 2 weeks, and 4 weeks, subjects were analyzed for clinical study and microbiological study. After 2 weeks and 4 weeks use of their respective toothpastes, statistically significant decreases of gingival index, plaque index, and bleeding index were shown in both the control and the experimental group. The degree of decrease was more significant in the experimental group than the control group. A statistically significant decrease of pocket depth, and gingival crevicular fluid were shown in both the control and lie experimental group. A statistically significant increase of cocci was shown in both the control and the experimental group, the degree of increase was more significant in the experimental group than control group. A statistically significant decrease ofnon-motile rods, and motile rods were shown in both the control and the experimental group, the degree of decrease was more significant in the experimental group than the control group. Spirochetes increased weakly in both the control and the experimental group but a statistic significance was not shown. A statistically significant decrease of anaerobic bacteria, aerobic bacteria, and black pigmented Bacteroides were shown in both the control and the experimental group. These results indicate that the use of toothpaste containing natural medicines is effective in the prevention and the treatment of periodontal diseases.

  • 동충하초속균은 곤충기생균으로 충체내에 균핵을 형성하며 단일 또는 총생의 stroma에 자낭각을 형성하는 균이다. 채집된 동충하초균은 Cordyceps militaris, C. nutans, C. sphecocephala, Isaria japonica와 Torrubiella sp. 등 5종이었다. 채집된 동충하초의 분리를 위하여 동충하초의 자실체를 샤레 뚜껑에 tape로 고정시킨 후 water agar가 들은 샤레에 짝을 맞추어 놓으면 자낭포자가 떨어지며 3시간 후 발아한 포자를 PDA에 이식하여 분리하였다. C. nutans와 C. militaris의 균사생장이 가장 우수한 배지는 Hamada media이며 complete media와 감자한천배지에서도 균사생장이 좋은 것으로 나타났다. 탄소원으로는 Mannose와 C. militaris와 C. nutans가 균사생장이 양호하였고 질소원으로는 glutamic acid에서 C. militaris가 asparagine에서는 C. nutans가 균사생장이 양호하였다. Vitamine은 Thiamine-HCI, Biotine, Nicotinic acid 모두 C. militaris와 C. nutans의 균사생장에 비슷하였다. C. nutans의 분생포자를 접종하였을 때 배추흰나비 유충, 노린재, 멸강나방, 배추좀나방은 살충력이 높았고, 메뚜기는 50%, 잣나무넓적잎벌은 12%의 살충력이 있으나 진딧물과 오리나무잎벌에서는 살충력이 없었다. C. nutans는 노린재에서만 채집되나 다른 곤충에도 살충효과가 인정되었다. 쌀가루 5g, 밀가루 5g에 물을 100ml을 넣고 배양한 것이 균사생장과 자실체 형성은 잘 되었으나 형성된 자실체는 완전한 동충하초가 아니고 분생포자의 덩어리라는 것이 현미경에 의해 관찰되었다.

  • 합성항산화제의 독성과 부작용으로 인한 천연물유래 항산화제에 대한 관심과 연구개발이 활발한 가운데 추출물 단계에서 ORAC assay를 통하여 우수한 항산화 활성을 가지는 쉬땅나무(Sorbaria sorbfolia var. stellipila Max.) 열매의 생물학적 생리활성 성분을 분리, 동정하기 위하여 국내에 자생하는 쉬땅나무의 열매를 채집하여 80% MeOH로 추출한 후 일반적인 용매분획법에 의해 분획한 분획물과 추출물을 대상으로 ORAC assay를 실시한 결과 80% MeOH추출물과 EtOAc, n-BuOH분획에서 천연항산화제인 trolox보다 우수한 활성이 나타났으며, 이중 가장 우수한 활성을 나타낸 EtOAc 분획물로 부터 각종 chromatography 기법을 통하여 분리, 정제한 결과 flavonoid계열의 화합물인 catechin을 단리 하였다. 단리 되어진 catechin은 쉬땅나무의 열매에서는 처음으로 본 연구에서 보고되는 성분으로 ORAC assay에서 대조군인 trolox에 비해 높진 않지만 유사한 활성이 나타나, vitamine E와 유사한 항산화 활성을 나타내는 것으로 보여지며, 따라서, 이 성분 외에 다양한 항산화 활성 성분들의 복합작용으로 인하여 쉬땅나무열매 추출물 및 분획물이 vitamine E에 비하여 3배 이상의 높은 항산화 활성이 나타나고 있음을 시사하는 바이다. 현재까지 쉬땅나무에 대한 식물학적 성분연구 및 유효활성 성분연구가 다른 천연물에 비하여 상대적으로 활발하게 이루어지지 않았으나, flavonoid계 화합물이 TLC확인 시험을 통하여 확인한 바 다양하게 존재하고 있어, 향후 이와 유사한 다양한 flavonoid계열의 화합물을 분리하여, 우수한 항산화 활성을 갖는 천연물의약품의 기초자료 제공 등 항산화 성분연구에 많은 기여를 할 수 있을 것으로 판단된다.
