  • 후추의 매운맛을 주는 자극성분인 piperine 정량에 대한 가능한 방법들에 관하여 조사정리 하였고 또 새로운 정량법으로 후추의 매운 성분을 $140^{\circ}C$에서 알카리 가수분해로서 유리된 piperidine을 p-nitrophenyl diazonium fluoborate reagent와 반응처리 시킴으로서 530nm에서 최고 흡광도를 보여주고 안정된 적색 복합화학물을 생성시켜 이 복합물의 색을 colorimeter로 측정하는 비색정량법을 개발하였다. 이 새로운 방법은 후추의 전 매운맛의 주성분인 piperine의 정량에 특히 유용하였다. 이 분석법의 장점은 일반 적정법보다 적은 양의 시료로서 후추에 함유된 자극성분인 piperine의 측정이 가능한 것이다.

  • It is previously reported that 6-paradol can induce prolonged analgesia in experimental animals. In order to investigate the mutagenicity of 6-paradol, Ames Samonella/microsome plate assay was carried out with Salmonella typhimurium strains, TA 98, TA 100, TA 1535 and TA 1538, 6-Paradol was nonmutagenic in Salmonella typhimurium with and without rat liver microsomal activation. The rec assay with Bacillus substilis strains H 17 $rec^+$ and M 45 $rec^+$ was carried out ot test 6-paradol and other compounds (1-3 mg/disc) for DNA damaging activity, 6-Paradol was also nonmutagenic in DNA damaging activity. The relative size of the inhibition zone for 6-paradol was smaller than that of capsaicin. We have also determined the pathological effects of this compound on the various tissues of rats after administrating(i.p.) with increasing doses of 4, 8, 12, 16 mg/kg at 2 hour intervals and found no significant changes in terms of histology.

  • Diabetes is marked by high glucose levels and is associated with decreased bone mass and increased fracture rates. To determine if [6]-gingerol could influence osteoblast dysfunction induced by 2-deoxy-D-ribose (dRib), osteoblastic MC3T3-E1 cells was treated with dRib and [6]-gingerol and markers of osteoblast function and oxidized protein were examined. [6]-Gingerol ($10^{-7}\;M$) significantly increased the growth of MC3T3-E1 cells in the presence of 30 mM dRib (p<0.05). [6]-Gingerol ($10^{-7}\;M$) caused a significant elevation of alkaline phosphatase (ALP) activity, collagen content, and osteocalcin secretion in the cells. We then examined the effect of [6]-gingerol on the production of osteoprotegerin and protein carbonyl in osteoblasts. Treatment with [6]-gingerol ($10^{-9}$ and $10^{-7}\;M$) increased osteoprotegerin secretion in osteoblastic cells. Moreover, [6]-gingerol ($10^{-9}$ and $10^{-7}\;M$) decreased protein carbonyl contents of osteoblastic MC3T3-E1 cells in the presence of 30 mM dRib. Taken together, these results demonstrate that [6]-gingerol inhibits dRib-induced damage and may be useful in the treatment of diabetes related bone diseases.

  • Objectives : The purpose of this study was to investigate the interpretation of the Soyo-san(SYS) prescription in order to obtain the evidence for clinical applications. Methods and Result : We interpreted on the SYS-related contents based on 25 classic books, analyzed it according to followed categories ; meaning of name, alteration of herbal composition according to age, usage, origin, physiological and pathological situation of SYS, description of each herbal drug Conclusion : 1. So(逍) mean diminish(消), 遙 mean roll(搖). It reflected feature of SYS, that alleviate depression without impairing vital energy(正氣). 2. SYS was first mentioned in the prescription of peaceful benevolent dispensary(太平惠民和劑局方), its essential application was harminizing liver depression and spleen deficiency(肝鬱脾虛) 3. SYS originated from Sayuk-san. Sayuk-san was appropriate for soothe the liver and regulate the spleen(疏肝理脾), while SYS was suitable for depressed liver and blood deficiency(肝鬱血虛) 4. Most medical literature insisted that application situation of SYS is blood deficiency(血虛), depressed liver(肝鬱), spleen deficiency(脾虛). And there is strong correlation between three factors. 5. Bupleurum falcatum L.(柴胡), Mentha arvensis L.(薄荷) alleviates liver depression as "pungent dissipate-qi uprais (辛散氣升)" nature. Angelica gigas Nakai(當歸), Paeonia lactiflora Pall.(白芍藥) emoliates the liver by nourishing the blood. Atractylodes japonica Koidz. ex Kitam.(白朮), Poria cocos(茯苓), Glycyrrhiza uralensis Fisch.(甘草), Zingiber officinale Roscoe(生薑) cultivate the basis as tonifying earth(補土).

  • Many studies have focused on the anticarcinogenic, antimutagenic or chemopreventive activi-ties of capsaicin (trans-8-methyl-N-vanillyl-6-nonenamide) which is a major pungent ingredient in red pepper. We have previously shown that capsaicin selectively induces apoptosis in H-ras-transformed MCF10A human breast epithelial cells but not in their normal cell counter-parts (Int. J. Cancer, 103, 475-482,2003). In this study, we investigated the possible roles of reactive oxygen species (ROS) and Rac1 in capsaicin-induced apoptosis of H-ras MCF10A cells. Selective induction of ROS generation by capsaicin treatment was observed only in H-ras MCF10A cells. Pretreatment of H-ras MCF10A cells with an antioxidant N-acetylcysteine(NAC) significantly reversed capsaicin-induced growth inhibition, suggesting that ROS may mediate the apoptosis of H-ras-transformed cells induced by capsaicin. Rac1 was prominently activated by H-ras in MCF10A cells. Based on the studies using a wild type Rac1 and a domi-nant negative Rac1 constructs, we propose that Rac1 activity is critical for inhibitory effect of capsaicin on growth of H-ras-transformed MCF10A cells possibly through ROS generation.

  • Bladder cancer is a common cancer with high risk of recurrence and mortality. Intravesicle chemotherapy after trans-urethral resection is required to prevent tumor recurrence and progression. It has been known that antioxidants enhance the antitumor effect of bacillus Calmette-Guerin (BCG), the most effective intravesical bladder cancer treatment. Capsaicin, the major pungent ingredient in genus Capsicum, has recently been tried as an intravesical drug for overactive bladder and it has also been shown to induce apoptotic cell death in many cancer cells. In this study, we investigated the apoptosis-inducing effect and alterations in the cellular redox state of capsaicin in MBT-2 murine bladder tumor cells. Capsaicin induced apoptotic MBT-2 cell death in a time- and dose-dependent manner. The capsaicin-induced apoptosis was blocked by the pretreatment with Z-VAD-fmk, a broad-range caspase inhibitor, or Ac-DEVD-CHO, a caspase-3 inhibitor. In addition to the caspase-3 activation, capsaicin also induced cytochrome c release and decrease in Bcl-2 protein expression with no changes in the level of Bax. Furthermore, capsaicin at the concentration of inducing apoptosis also markedly reduced the level of reactive oxygen species and lipid peroxidation, implying that capsaicin may enhance the antitumor effect of BCG in bladder cancer treatment. These results further suggest that capsaicin may be a valuable intravesical chemotherapeutic agent for bladder cancers.

  • The effects of capsaicin, a pungent principle of hot red pepper, on body fat gain, balance serum lipid values were investigated in rats fed a high-fat(30%) diet. Administration of capsaicin by dietary administration caused a complete cessation of increased in body weight and fat gain induced by the high-fat diet. However, energy intake and body protein gain were not affected by capsaicin. Therefore, the suppression of body fat gain by capsaicn was believed due to an increased in energy expenditure. Simultaneous administration of capsaicin and a $\beta$-adrenergic blocker, propranolo, resulted in the inhibition of changes in body fat gain by capsaicin without remained unchanged, indicating an increase in the number of mitochondria in brown adipose tissue. Therefore, it appears that capsaicin possesses potent body fat suppressive effects mediated by $\beta$-adrenergic stimulation in which brown adipose tissue may be involved. On the other hand, capsaicin had no effects on serum triglyceride, total cholesterol or HDL-cholesterol levels. These results are in contrast to those reported by other investigators. Perhaps expression of the effects of capsaicin on plasma lipids is a rather complicated process, dependent on the type of diet administered, fat content of the diet, period and route of capsaicin administration, and species and strain of animals used.

  • The onion (Allium cepa L.) is the most widely cultivated species of the genus Allium, especially it has been valued because of the pungent flavor and aroma. Allium species including onion has very large genome sizes ranging from approximately 10 to 20 Gbp, which have complicated genomic studies and precluded genome sequencing until recently. A population of 186 F2 individuals derived from a cross of 'Umjinara' ${\times}$ 'Sinsunhwang' and the two parental lines were used for this study. For the development of framework map, various types of markers including SSRs, RAPD, SNPs, and CAPS makers have been used for polymorphism test. Especially, a lot of SNP and CAPS loci were developed from the onion transcriptome sequence by RNASEQ of two parental lines. The GBS libraries have been constructed based on a modified protocol from Poland Lab using a two-enzyme system. We have been developing markers showing polymorphism between two parental lines, and genotyping for all F2 individuals were finished for a number of polymorphic markers. For the construction of GBS libraries, a set of 192 barcoded adapters were generated from complementary oligonucleotides with XhoI overhang sequence and unique barcodes of length 4-8 bp and they have been tested using two parental linesto determine the optimum conditions for GBS analysis.

  • Chili pepper (Capsicum annum) is origin of subtropical region, and has been spread all over the world. It is increasing the production and consumption in recent year. Chili peppers are readily incorporated into local South Asian cuisines perhaps because people are already familiar with pungent and spicy flavors. Chili peppers, despite their fiery "hotness", are one of very popular spices known for their medicinal and health benefiting properties. Especially in South East Asia, they grow up so many cultivars of them recently, so it is so important crop world wide. In South East Asia, there are some articles about chili pepper in Thailand and Indonesia, but in Vietnam there is not so much information about chili pepper. In this paper, we analyzed genetic diversity in Vietnamese Chili pepper through the survey of local chili pepper. As a result, we got 38 kinds of chili fruits, 26 kinds of leaves and some information from farmers all in Vietnam. And I made the phylogenetic tree by SSR with 10 DNA markers. Finally we found the genetic similarities by regions.
