골관절염에 대한 참당귀 추출분말의 치료효과를 검토하고자 흰쥐의 monosodium iodoacetate(MIA)로 유발된 골관절염 부위에서 시료를 채취하여 염증관련 효소 및 염증성 cytokines의 발현에 대하여 참당귀 추출분말의 억제효능을 검토하였다. 고농도의 참당귀 추출분말 (50 μg/mL) 투여에서도 독성이 관찰되지 않았으며, 동일조건하에서 interleukin-1α (IL-1α)로 유발된 nitric oxide (NO)의 생성을 효과적으로 억제하였다. 특히, 관절연골 조직의 inducible nitric oxide synthase (iNOS) 및 cyclooxygenase-2(COX-2)의 발현을 농도 의존적으로 억제하였다. 따라서 참당귀 추출분말은 항염증 효능을 나타내는 농도에서 독성 없이 사용할 수 있으며, iNOS발현을 억제하여 방출되는 신호전달 물질인 NO의 생성을 억제하였다. 또한 참당귀 추출분말의 처리로 염증유발 부위에서 염증성 cytokines으로 알려진 tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β) 및 interleukin-6 (IL-6)의 발현이 억제됨을 확인하였다. 참당귀 추출분말의 항 염증효과는 TNF-α, IL-1β 및 IL-6의 혈중농도를 낮추어 염증부위뿐만 아니라 전체적으로 항염증효과를 나타내었다. 본 실험결과, 참당귀 추출분말의 투여는 MIA 또는 IL-1α로 유발되는 골관절염 동물모델에서 염증인자, 관련 효소의 발현 및 관련 신호전달 물질의 생성을 효과적으로 억제하여, 슬관절의 활액 내 glycosaminoglycan (GAG) 및 관절연골의 proteoglycan (PG)의 분해를 방지하여 골관절염의 발생을 억제할 것으로 추정되었다. 한편, 참당귀 추출분말의 주성분인 decursin은 혈중에서 2시간이내에 decursinol로 전환되어 8시간이상 LC-MS/MS로 검출되었다, 따라서 참당귀 추출분말에 의한 염증성 사이토카인 TNF-α, IL-1β 및 IL-6의 억제활성은 항염증활성이 큰 decursinol에 의한 것으로 추정된다.

Fucoidan은 갈조류로부터 추출되는 황산다당류로 다양한 생리학적 활성을 갖고 있다. 본 연구의 목적은 LPS로 자극한 돼지 말초혈액 단핵구세포(PBMCs)의 NO 생산에 있어 fucoidan의 효과를 검토하고, 이러한 효과가 iNOS의 발현과 AP-1의 활성화와 관련이 있는지를 조사하는데 있다. LPS 무처치 돼지 PBMCs에서 fucoidand의 처리는 NO 생산과 AP-1활성에 대해 효과를 보이지 않았다. 또한 iNOS와 AP-1의 mRNA 발현도 fucoidan 처치에 의해 영향을 받지 않았다. 그러나 LPS로 자극한 PBMCs에서는 NO 생산과 AP-1의 활성 그리고 iNOS와 AP-1의 mRNA 발현이 현저하게 증가하였다. 이와 같은 LPS에 의한 돼지 PBMCs의 NO 생산과 AP-1 활성증가는 fucoidan 첨가에 의해 감소되었다. 또한 fucoidan은 LPS에 의한 iNOS와 AP-1의 mRNA 발현증가도 억제시켰다. 이상의 결과는 fucoidan이 LPS 자극 돼지 PBMCs에서 iNOS 발현과 AP-1 활성의 억제와 함께 NO 생산을 하향 조절함으로써 항염증효과를 나타내는 것으로 사료되었다.

Objectives In the present study, the author intended to investigate whether bojung-ikgitang-gamibang(BJGB) and seonbang-paedoktang(SBPT) significantly affect in vivo and in vitro mucin secretion from airway epithelial cells. Methods In vivo experiment, mice's mucin which is on a hypersecretion of airway mucin, mice's tracheal goblet cells in hyperplasia and mice's intraepithelial mucosubstances were exposed with SO2for3weeks. Effects of orally-administered BJGB and SBPT during 1 week on vivo mucin secretion and hyperplasia of tracheal goblet cells were assessed by using both enzyme-linked immunosorbent assay(ELISA) and staining goblet cells with alcian blue. In vitro experiment, confluent hamster tracheal surface epithelial(HTSE) cells were metabolically radiolabeled with 3H-glucosamine for 24hrs and chased for 30 min in the presence of each agent to figure out the effectiveness of 3H-mucin secretion. Total elution profiles of control spent media and treatment sample through Sepharose CL-4B column were analyzed. The effects of each agent on contractility of isolated tracheal smooth muscle and effects of each agent on MUC5AC gene expression in cultured HTSE cells were investigated. Also, possible cytotoxicities of each agent were assessed by measuring lactate dehydrogenase(LDH) release. Additionally, effects of BJGB and SBPT on both MUC5AC gene expression in cultured HTSE cells and TNF- or EGF-induced MUC5AC gene expression in human airway epithelial cells (NCI-H292) were investigated. Results (1) BJGB and SBPT inhibited hypersecretion of in vivo mucin. SBPT also inhibited the increase the number of goblet cells. However, BJGB did not affect the increase of number of goblet cells; (2) BJGB significantly increased mucin secretion from cultured HTSE cells, without significant cytotoxicity, and chiefly affected the 'mucin' secretion; (3) SBPT did not affect mucin secretion from cultured HTSE cells without significant cytotoxicity, and also did not affect the secretion of the other releseable glycoproteins; (4) BJGB and SBPT did not affect Ach-induced contraction of isolated tracheal smooth muscle; (5) SBPT significantly inhibit the expression levels of MUC5AC gene and BJGB significantly increased the expression levels of MUC5AC gene in both HTSE cells and NCI-H292 cells. Conclusions BJGB and SBPT can not only affect the secretion of mucin but also affect the expression of mucin gene. The author suggests that the effects BJGB and SBPT with their components should be further investigated and it is highly desirable to find from oriental medical prescriptions, novel agents which might regulate hypersecretion of mucin from airway epithelial cells.

Cordyceps species including Cordyceps bassiana are a notable anti-cancer dietary supplement. Previously, we identified several compounds with anti-cancer activity from the butanol fraction (Cb-BF) of Cordyceps bassiana. To expand the structural value of Cb-BF-derived anti-cancer drugs, we employed various chemical moieties to produce a novel Cb-BF-derived chemical derivative, KTH-13-amine-monophenyl [4-isopropyl-2-(1-phenylethyl) aniline (KTH-13-AMP)], which we tested for anti-cancer activity. KTH-13-AMP suppressed the proliferation of MDA-MB-231, HeLa, and C6 glioma cells. KTH-13-AMP also dose-dependently induced morphological changes in C6 glioma cells and time-dependently increased the level of early apoptotic cells stained with annexin V-FITC. Furthermore, the levels of the active full-length forms of caspase-3 and caspase-9 were increased. In contrast, the levels of total forms of caspases-3, caspase-8, caspase-9, and Bcl-2 were decreased in KTH-13-AMP treated-cells. We also confirmed that the phosphorylation of STAT3, Src, and PI3K/p85, which is linked to cell survival, was diminished by treatment with KTH-13-AMP. Therefore, these results strongly suggest that this compound can be used to guide the development of an anti-cancer drug or serve as a lead compound in forming another strong anti-proliferative agent.

Drug-induced liver injury (DILI) is the serious and fatal drug-associated adverse effect, but its incidence is very low and individual variation in severity is substantial. Acetaminophen (APAP)-induced liver injury accounts for >50% of reported DILI cases but little is known for the cause of individual variations in the severity. Intrinsic genetic variation is considered a key element but the identity of the genes was not well-established. Here, pre-biopsy method and microarray technique was applied to uncover the key genes for APAP-induced liver injury in mice, and a cause and effect experiment employing quantitative real-time PCR was conducted to confirm the correlation between the uncovered genes and APAP-induced hepatotoxicity. We identified the innately and differentially expressed genes of mice susceptible to APAP-induced hepatotoxicity in the pre-biopsied liver tissue before APAP treatment through microarray analysis of the global gene expression profiles (Affymetrix $GeneChip^{(R)}$ Mouse Gene 1.0 ST for 28,853 genes). Expression of 16 genes including Gdap10, Lpl, Gabra3 and Ccrn4l were significantly different (t-test: FDR <10%) more than 1.5 fold in the susceptible animals than resistant. To confirm the association with the susceptibility to APAP-induced hepatotoxicity, another set of animals were measured for the expression level of selected 4 genes (higher two and lower two genes) in the liver pre-biopsy and their sensitivity to APAP-induced hepatotoxicity was evaluated by post hoc. Notably, the expressions of Gabra3 and Lpl were significantly correlated with the severity of liver injury (p<0.05) demonstrating that these genes may be linked to the susceptibility to APAP-induced hepatotoxicity.

Previous studies have shown that bone marrow mesenchymal stromal cell (MSC) transplantation significantly improves the recovery of neurological function in a rat model of intracerebral hemorrhage. Potential repair mechanisms involve anti-inflammation, anti-apoptosis and angiogenesis. However, few studies have focused on the effects of MSCs on inducible nitric oxide synthase (iNOS) expression and subsequent peroxynitrite formation after hypertensive intracerebral hemorrhage (HICH). In this study, MSCs were transplanted intracerebrally into rats 6 hours after HICH. The modified neurological severity score and the modified limb placing test were used to measure behavioral outcomes. Blood-brain barrier disruption and neuronal loss were measured by zonula occludens-1 (ZO-1) and neuronal nucleus (NeuN) expression, respectively. Concomitant edema formation was evaluated by H&E staining and brain water content. The effect of MSCs treatment on neuroinflammation was analyzed by immunohistochemical analysis or polymerase chain reaction of CD68, Iba1, iNOS expression and subsequent peroxynitrite formation, and by an enzyme-linked immunosorbent assay of pro-inflammatory factors (IL-$1{\beta}$ and TNF-${\alpha}$). The MSCs-treated HICH group showed better performance on behavioral scores and lower brain water content compared to controls. Moreover, the MSC injection increased NeuN and ZO-1 expression measured by immunochemistry/immunofluorescence. Furthermore, MSCs reduced not only levels of CD68, Iba1 and pro-inflammatory factors, but it also inhibited iNOS expression and peroxynitrite formation in perihematomal regions. The results suggest that intracerebral administration of MSCs accelerates neurological function recovery in HICH rats. This may result from the ability of MSCs to suppress inflammation, at least in part, by inhibiting iNOS expression and subsequent peroxynitrite formation.

The aim of this study is to look at how pepper was used in traditional medicine. In other words, this study aims to take a look at the process by which the medicinal nature & efficacy of pepper in traditional society was perceived and arranged through the aspects of the use of pepper as an exotic crop for treating diseases. This study investigated cases of using pepper for medical treatments by referring to books on traditional medicine in Korea. The old records about pepper are mainly in empirical medical books from the late Chosun dynasty. Nevertheless, the records about pepper tend to decrease in medical text as time goes by. Such a phenomenon can be attributable to the fact that people began to use pepper for daily food life rather than for medicinal purposes. Pepper was used mostly for digestive trouble such as vomiting, diarrhea, and stomachaches, and it was also applied to mental and aching diseases caused by the sound of body fluids remaining in the stomach. In addition, there were many cases where pepper was used externally for surgical disorders. Such symptoms for treatment are linked to, or in a complementary relationship with, research results in modern times. Boiled pepper was generally taken in the traditional herbal decoction method, and in the case of surgical diseases, it was applied externally. The cases of using old pepper, using pepper with seeds or without seeds, and using pepper mixed with sesame oil belong to a sort of herbal medicine processing, which usually aimed at changing the medicinal nature of pepper. In addition, in relation to the eating habits at that time, pepper was used as seasoning and to make red pepper paste with or without vinegar. There are two words used for pepper in the medical textbooks, 苦椒 (gocho) and 烈棗 (yeoljo). These words are translated into Korean as gochu, so we can identify this word as a nickname for pepper.

밀전분으로 가열-냉각과정에 의해 제조한 RS3와 가교결합에 의한 RS4를 박력분에 대해 10, 20, 30% 혼합하여 밀가루의 특성을 측정하고 쿠키를 제조하여 그 품질을 이화학적 및 관능적 특성으로 비교하였다. RS를 첨가하면 밀가루의 단백질 함량이 감소하였으며 저항전분 함량은 7.0%에서 9.6-17.9%로 증가하였으며 RS4 첨가 시 그 증가폭이 컸다. RS 혼합 밀가루의 팽윤력은 약간 감소하였으나 용해도는 RS3 첨가 시 2-3배 증가하였다. 신속점도측정기에 의한 RS 혼합 밀가루의 호화개시온도는 높아졌으나 최고점도, 유지점도, 냉각점도는 감소하였는데 첨가량이 증가할수록 그 감소 정도가 컸다. RS 첨가 밀가루의 breakdown과 total setback viscosity가 감소하여 RS 첨가로 전분의 노화가 억제 될 것으로 생각되었다. 황색도는 RS3 첨가 시 증가하였으나 RS4 첨가로 감소하였다. 관능평가 결과 RS 첨가는 쿠키의 모양, 색깔, 전체적인 품질이 유의적인 차이를 보였으며(p<0.05), AACC 표준쿠키에서 모양과 색깔이 RS를 첨가한 경우 개선되었다. RS 첨가로 쿠키의 텍스쳐도 영향을 주었으며 전체적인 품질은 땅콩쿠키나 AACC 표준쿠키 모두 RS를 첨가한 경우 개선됨을 알 수 있었다. RS3와 RS4를 밀가루 기준으로 30% 첨가하여 쿠키를 제조하면 저항전분 함량은 6.4%와 10.9% 증가하면서 품질도 개선하였다.

This study was designed to examine the tissue levels of interleukin-$1{\alpha}$(IL-$1{\alpha}$), interleukin-$1{\beta}$(IL-$1{\beta}$) and tumor necrosis factor-${\alpha}$(TNF-${\alpha}$) in inflamed human dental pulps and periapical lesions, and to determine the relationship between each cytokine and pulpal and periapical pathosis. The pulps used in this experiment, were obtained in routine endodontic treatment and the periapical lesions in periapical surgery after clinical diagnoses were performed. These specimens were divided into four groups as normal pulp group(control group, n=9), acute pulpitis group(n=g), chronic pulpitis group(n= 10) and periapical lesion group(n= 18) and stored in liquid N2. For extract preparation, tissues were finely minced with a scalpel, and the fragments were incubated in $0.5m\ell$ homogenizing buffer (0.1 mol/L potassium chloride, 0.02 mol/L TRIS; pH=7.6) for two hours and grinded with glass homogenizer. Debris was removed by centrifugation and supernatants were immediately tested with enzymelinked immunosorbent assay (ELISA, R&D Co., Minneapolis, USA). Following results were obtained; 1. The concentrations of IL-$1{\alpha}$ in all experimental groups were significantly higher than in control group(p<0.05). And the concentrations of IL-$1{\alpha}$ in periapical lesion group were somewhat higher than in two pulpitis groups, but the differences among those groups were not stastically significant (p>0.05). 2. The concentrations of IL-$1{\beta}$ in all experimental groups were significantly higher than in control group (p<0.05), and all the experimental groups expressed similar concentrations. 3. The concentrations of TNF-${\alpha}$ in all experimental groups were higher than in control group but only the differences between chronic pulpitis group and control group were statistically significant(p<0.05). And the concentrations of TNF-${\alpha}$ in acute and chronic pulpit is groups were higher than in periapical lesion group but only the differences between chronic pulpitis group and periapical lesion group were statistically significant (p<0.05). 4. There was significant correlation only between IL-$1{\alpha}$ and IL-$1{\beta}$ in periapical lesion group (p<0.05).
