  • The purpose of this study is to investigate effects of natural incense on the preservation of paper- and textile-based remains and the kinds and applications of natural anti-insect incense by reviewing relevant literatures of the ancient times. There are few ancient literatures of incense published in Korea. The researcher deducted how incense was used in this nation through reviewing verses contained in ancient literatures and medical books. In contrast, the kinds and applications of anti-insect incense used in China, where incense culture prospered, were investigated here through reviewing technical books about incense published during the Song(宋) and Ming(明) periods, $\ll$Incense record(香譜)$\gg$, $\ll$Chen's Incense record(陳氏香譜)$\gg$ and $\ll$Incense record(香乘)$\gg$. There were several methods of keeping clothes better from insects. In relation, how to use anti-insect incense varied in accordance with main materials of clothes, paper, textile, leather and others. Cymbopogon dstans(芸香), Brassica rapu var and Incarvillea sinensis(角蒿) are anti-insect incense which were used for paper. Anti-insect incense for textiles is classified into single and mixed incenses depending on whether only one kind of incense was used or more than seven kinds of the substance. Acori rhizoma(菖蒲), Capsella bursa-pastoris(薺菜花), Lactuca sativa L., Erigeron canadensis(莽草), Stemona japonica(百部) and Moschus sifanicus(麝香) are single anti-insect incense which were used for textile. While, the latter was called. ‘Yi Xiang(衣香)’ is mixed anti-insect incense which was used for textile. Artemisia asiatica(艾葉) and Zanthoxylum schinifolium(花椒) are anti-insect incense which were used for leather. Angelica dahurica(芳香) and Bamboo are anti-insect incense which were used for others. There were three main methods of using incense to prevent insects, that is, diffusing incense's strong scent and ingredients, exposing to smokes from burnt incense and washing with incense-boiled water. Diffusing incenses had a strong scent and antibiotic ingredients, which were put between books or clothes or into a storage box without being processed. If necessary, however, they were processed into rough powders that were in turn used singly, or otherwise mixed for a stronger scent and better insect elimination. Exposing to smokes from burnt incense was done as follows. A clothes was put on 'Long(籠)' underneath which there was a boiling water. The clothes was humidified by the water and then exposed to smokes from burnt incense. 'Long(籠)' had been long used since it was manufactured in the QinHan(秦漢) period for the first time. A local literature, $\ll$Koryo TuGing(高麗圖經)$\gg$ shows that in the Koryo(高麗) period, BoShaLu(博山爐) were used as a means of exposing clothes to smokes to prevent moths, similarly to China. Washing clothes with incense-boiled water was more effective in removing lots of worms and germs from clothes, but leaving the scent and ingredients of the used incense and maintaining the effect of anti-insect.

  • 한약재에서 추출한 해충기피용액과 실리카를 혼합하여 해충기피 실리카 졸을 제조하고, 분무건조법을 이용하여 마이크로 단위의 해충기피용액이 포함된 다공성 구형 분말을 제조하였다. 분무건조법을 통해 제조된 해충기피 분말의 특성분석을 위해 해충기피 졸의 농도(해충기피용액, 실리카) 및 분무 건조 장비의 조건에 따라 분말 모폴로지, 입자크기별 입경분포, 열적 안정성 분석을 실시하였다. 해충기피 졸의 농도가 4, 7 wt% 및 10 wt%일 때 각각 평균 입자 크기가 8.3, $9.5{\mu}m$$11.7{\mu}m$ 순으로 농도가 증가할수록 분말의 직경이 커졌다. 반면에 빠른 가스 주입속도 상태에서 노즐입구온도 및 용액주입속도 증가에 의한 분말 입경의 증가는 미미하였다. 또한, 열중량 분석법을 통하여, 구형의 다공성 분말 안에 해충기피 용액이 담지 되어있고, 이들은 $200^{\circ}C$까지 열적 안정성이 확보됨을 확인하였다. 분무건조를 통한 해충기피 분말은 평균 $9{\sim}10{\mu}m$이고, 열적 안정성을 가지므로 컴파운딩 및 필름제조공정에 응용이 가능할 것으로 기대된다.

  • 본 연구의 목적은 식품 포장재를 뚫고 침입하여 식품에 큰 피해를 입히는 화랑곡나방 유충의 유입을 방지하기 위한 방충향낭을 개발하는 것이다. 방충 물질로는 해충에 대해 살충 및 기피력을 가지는 것으로 알려진 회향의 에센셜오일인 회향오일(FO)을 선정하였다. 훈증테스트를 통하여 화랑곡나방 유충에 대해 FO의 훈증사멸 효과를 관찰하였고 120시간 후 FO은 약 56%의 사멸률을 보였다. 이 후 포장기법 중 하나인 향낭 기법을 사용하여 FO 향낭을 제조하여 기피효과를 측정하였다. 그 결과, FO 향낭은 무처리구와 비교하여 유의적인 기피효과를 보였다. 하지만 휘발성이 강한 에센셜오일의 특성으로 인해 48시간에서의 기피력이 24시간이 지난 향낭의 기피력보다 낮은 것을 볼 수 있었다. Gas chromatography를 이용한 FO 향낭의 방출 경향 분석에 따르면 오일의 총 방출량 및 trans-aenthole의 함량이 일정 시간 이후 점차 방출량이 줄어드는 경향을 보였다. 따라서 FO 향낭은 방충력을 가지는 것으로 분석되지만 높은 휘발성으로 인해 기피력은 시간이 지날수록 감소할 것으로 보인다.

  • Silkworm pupae, a by-product of the silk industry are known to be valuable resource of nutrients for humans as well as animals besides encompassing diverse bioactive constituents. However, there is a paucity of knowledge on their role in amelioration of oxidative stress and anti-skin aging properties. In the present study, we evaluated the inhibitory effect of aqueous as well as ethanolic (30% and 70%) extracts from distinct stages of male and female silkworm pupae belonging to two silkworm varieties on skin aging-related enzymes. The activities of collagenase, elastase and tyrosinase were effectively inhibited by 70% ethanolic silkworm pupal extracts (SPE), followed by 30% with aqueous extracts exhibiting meager inhibitory potential. SPE were also investigated for their antioxidant activity in oxidative-stressed murine fibroblasts (L929). The intracellular ROS and lipid peroxidation induced by tert-butyl hydroperoxide (t-BHP) in fibroblasts was better attenuated by pre treatment with ethanolic (30%) and aqueous extracts, respectively. The safety of the extracts was determined by studying their effect on fibroblast cell viability and it was found that none of the extracts were cytotoxic. Our findings indicate the potential utility of SPE as anti-aging components in cosmeceuticals.

  • Lipoprotein-associated phospholipase $A_2\;(Lp-PLA_2)$ is a potential biomarker of coronary heart disease and plays an important proinflammatory role in the progression of atherosclerosis. Also acyl-CoA: cholesterol acyltransferase (ACAT) and oxidized low-density lipoprotein (LDL) playa key role in atherosclerosis, respectively. And so, the inhibitory activities of the methanol extracts of 42 insect resources were examined on $Lp-PLA_2$, ACAT, and LDL oxidation for screening of anti-atherogenic substances. Among them, the methanol extracts of Eurydema rugosa significantly inhibited all of upper three activities. Several kinds of tested insects having high inhibitory effect with the methanol extracts were extracted with n-hexane, ethyl acetate, and acetone, and their inhibitory activities were tested.

  • We have previously shown that the addition of silkworm hemolymph to a culture medium increases the longevity of insect and mammalian cells by inhibiting apoptosis. This indicates that the component which inhibits apoptosis is contained in the silkworm hemolymph, The apoptosis-inhibiting component was isolated from silkwonn hemolymph and characterized in our previous study. A database search using the N-terminal amino acid sequence of this component as a template resulted in a 95% homology with a low molecular weight lipoprotein, the so called ’30K protein' of unknown function. In this study, the 30K protein gene was expressed in mammalian and insect cells to confirm the apoptosis-inhibiting effect. The overexpression of 30K protein in mammalian cell inhibited the staurosporin-induced apoptosis by the prevention of the activation of caspase 3. Using an Autographa californicanuclear polyhedrosis virus (AcNPV) system, the 30K protein was overexpressed also in insect cells. The expression of the 30K protein increased the longevity of baculovirus-infected insect cells by inhibiting apoptosis. These results suggest that the 30K protein is a novel anti-apoptotic protein.

  • Recently, we demonstrated that human serum amyloid P component (SAP) specifically recognizes exposed bacterial peptidoglycan (PGN) of wall teichoic acid (WTA)-deficient Staphylococcus aureus ${\Delta}$tagO mutant cells and then induces complement-independent phagocytosis. In our preliminary experiments, we found the existence of human serum immunoglobulins that recognize S. aureus PGN (anti-PGNIgGs), which may be involved in complement-dependent opsonophagocytosis against infected S. aureus cells. We assumed that purified serum anti-PGN-IgGs and S. aureus ${\Delta}$tagO mutant cells are good tools to study the molecular mechanism of anti-PGN-IgG-mediated phagocytosis. Therefore, we tried to identify the intracellular molecule(s) that is involved in the anti-PGN-IgG-mediated phagocytosis using purified human serum anti-PGN-IgGs and different S. aureus mutant cells. Here, we show that anti-PGN-IgG-mediated phagocytosis in phorbol myristate acetate-treated U937 cells is mediated by $Ca^{2+}$ release from intracellular $Ca^{2+}$ stores and anti-PGN-IgGdependent $Ca^{2+}$ mobilization is controlled via a phospholipase C${\gamma}$-2-mediated pathway.

  • 동충하초(Cordyceps)는 B.C. 2,000년 이후로부터 지금까지 중국, 한국, 일본 등 아시아 국가에서 잘 알려진 전통적인 불로장생의 비약으로 사용되어져 왔다. 곤충기생 곰팡이균으로서 원조 동충하초로 불리는 Cordyceps속에 속하는 Cordyceps sinensis는 우리나라 한반도에서는 발견되지 않고 있다. 그 이유는 해당 곰팡이균에 특정적인 기주곤충인 박쥐나방(Hepialus armonicanus)이 우리나라에는 존재하지 않기 때문으로 보인다. 따라서 차선책으로서 한국형의 동충하초, 즉 Paecilomyces tenuipes 동충하초균에 대한 곤충생체배지로서 누에(Silkworm, Bombyx mori)를 기주곤충으로 사용하는 누에동충하초의 인공적인 생산방법을 세계 최초로 개발하게 된 것이다. 따라서 본 총설은 누에동충하초를 개발하게 된 역사적 배경과 생산방법 및 약리학적 효능과, 비곤충유래 동충하초인 인공배지 배양동충하초(밀리타리스동충하초: Cordyceps militaris, 붉은자루동충하초: Cordyceps pruinosa 등)의 배양조건과 동충하초 품종육성, 배지배양조건, 동충하초의 식품에의 응용 가능성, 화학적 구성성분 및 약리적 효능 등에 대해 고찰하였다. 곤충유래의 누에동충하초 및 비곤충유래동충하초균사체 및 자실체동충하초의 주요 약리작용은 항종양, 면역증강, 항피로, 항스트레스, 항산화, 항노화, 항당뇨, 항염증, 항혈전, 항지질 및 해충방제 효능으로 요약된다. 동충하초의 주요 생리활성물질들은 단백다당체(헥소스, 헥소사민), 코디세핀, 만니톨, 산성다당체 등이다. 단백다당체와 부타놀 추출물은 매우 강한 항종양 효과를 보이나 세포독성은 나타내지 않았다. 만니톨은 종양유발쥐의 수명을 유의성 있게 연장하였다. 에르고스테롤은 항종양 활성은 보이지 않았으나 왕성한 식세포활성을 보였다. 따라서 우리가 높은 관심을 가지고 있는 누에동충하초의 항종양 활성은 세포독성효과보다는 면역력증강효과에 기인하는 것으로 사료된다[164].
