  • Rubiae radix belonging to the family Rubiaceae have been used in traditional medicine to blood stasis and hemostasis. In this study, we reported that methanol extract of Rubiae radix (RRME) induced apoptotic cell death through MAPKs activation in human promylocytic leukemia (HL-60) cells. The cytotoxic activity of activity of RRME in HL-60 cells was increased in a dose-dependent manner. RRME was cytotoxic to HL-60 cells, with IC50 of $8{\mu}g/mL$. Treatment of RRME to HL-60 cells showed apoptotic bodies, and the fragmentation of DNA, suggesting that these cells underwent apoptosis. Caspase-3 activity and PARP cleavage were time-dependently increased the expression of Bcl-2 and Bax. And ratio of Bax/Bcl-2 protein expression. Activation of p38 and JNK were increased 6 hr after RRME treatment in HL-60 cells, but activation of ERK was reduced 24 hr after treatment. Taken together, these results suggest that RRME induces apoptotic cell death through activation of p38 and JNK in HL-60 cells.

  • To explore the possible cancer therapeutic application of "Bo-yang-hwan-oh-tang" (BH), a herbal medicinal recipe used for improvement of blood stasis, we have examined its direct cytotoxicity against tumor cell, and induction of cytotoxic activity of lymphocytes. Water extract of BH alone did not exhibit direct cytotoxicity to Yac-1 target cells even with high concentrations (10 mg/ml). By exposure for 3 days, BH did not induce any nonspecific cytotoxic activity of mouse spleen cells, either, when assessed in a 4 hr $^{51}Cr-release$ assay. However, when BH was added during CD3 stimulation of non-adherent spleen cells, non-specific CTL activity was markedly promoted in a dose dependent manner. In contrast, BH did not alter activated NK cell activity following IL-2 stimulation. These data suggest that BH does not induce but upregulates non-specific CTL effecter function and that activated NK cell does not respond to BH. For elucidation of the mechanism underlying this function of BH, time kinetic study for IL-2 production using ELISA was undertaken. IL-2 production following CD3 stimulation was significantly augmented and higher level of IL-2 is sustained over 3 days in the culture medium by BH treatment. Moreover, addition of exogenous IL-2 during CD3 stimulation resulted in a similar level of cytotoxicity between control and BH-treated culture. These data indicate that the BH-mediated upregulation of non-specific CTL activity is contributed by augmentation of IL-2 production. Our data imply the possible application of BH for combination therapy of cancer with non-specific activator.

  • Root extracts of Angelica gigas and A. acutiloba have been used traditionally for the treatment of gynecological diseases, as well as anemia, blood stasis, and inflammatory pain, as blood tonics in Oriental medicine. In the present study, we investigated the effects of A. gigas and A. acutiloba on inflammatory mediators in mouse macrophages and compared their activities. Many studies suggest that prostaglandin $E_2$ ($PGE_2$) biosynthesis and nitric oxide (NO) production play important roles in the processes of both inflammation and carcinogenesis. Ethanolic extracts from the roots of both species exhibited significant inhibitory effects on $PGE_2$ generation in lipopolysaccharide-stimulated RAW 264.7 cells. In particular, the extract from A. gigas was more effective than that from A. acutiloba. Although neither inhibited NO generation, the extract from A. acutiloba stimulated NO generation. Our results suggest that the roots of A. gigas might possess more anti-inflammatory and/or cancer chemopreventative activity than that of A. acutiloba due to the suppression of cyclooxygenase-2 (COX2)-mediated $PGE_2$ production. In addition, A. acutiloba might exert anti-tumor activity through an increase in macrophage-produced NO.

  • Lymphedema is a chronic disorder characterized by lymph stasis in the subcutaneous tissue. Lymphatic fluid contains several components including hyaluronic acid and has many important properties. Over the past few years, significant research has been performed to identify an ideal tissue to implant as a filler. Because of its unique composition, fat harvested from the lymphedema tissue is an interesting topic for investigation and has significant potential for application as a filler, particularly in facial rejuvenation. Over a 36-month period, we treated and assessed 8 patients with lymphedematous limbs who concurrently underwent facial rejuvenation with lymphedema fat (LF). We conducted a pre- and postoperative satisfaction questionnaire survey and a histological assessment of the harvested LF fat. The overall mean general appearance score at an average of 6 months after the procedure was $7.2{\pm}0.5$, demonstrating great improvement. Patients reported significant improvement in their skin texture with a reading of $8.5{\pm}0.7$ and an improvement in their self-esteem. This study demonstrates that LF as an ideal autologous injectable filler is clinically applicable and easily available in patients with lymphedema. We recommend the further study and clinical use of this tissue as it exhibits important properties and qualities for future applications and research.

  • Spatholobus suberectus belonging the family Leguminosae has been used for promoting blood circulation, removing blood stasis, tonifying the blood, relaxing tendons, stopping internal bleeding and eliminating dampness in oriental traditional medicine. This study investigates whether the water extracts of S. suberectus induce apoptotic cell death in Jurkat T-acute lymphoblastic leukemia (ALL) cells. Jurkat cells were increased inhibitions of cell viability in a concentration-dependent manner by S. suberectus, as measured by cell morphology. The capability of S. suberectus to induce apoptosis was associated with proteolytic cleavage of specific target protein such as poly (ADP­ribose)polymerase protein suggesting the possible involvement of caspases. The purpose of the present study is also to investigate the effect of S. suberectus on cell cycle progression. G1 checkpoin related gene products tested (cyclin D1, cyclin dependent kinase 4, retinoblastoma, E2Fl) were decreased in their protein levels in a dose-dependent manners after treatment of the extract. These results indicate that the increase of apoptotic cell death by S. suberectus may be due to the inhibition of cell cycle progression in wild type p53-lacking Jurkat cells.

  • Crataegii Fructus is commonly used as a improving digestion, removing retention of food, promoting blood circulation and resolving blood stasis agent in East Asia. Cadmium (Cd) is widely distributed in the environment due to its use in industry. An exposure to Cd causes dysuria, polyuria, chest pain, hepatic and renal tubular diseases. The liver is the most important target organ when considering Cd-induced toxicity because Cd primarily accumulates in the liver. This study investigated the protective effect of Crataegii Fructus water extract against cadmium ($CdCl_2$, Cd)-induced liver toxicity in H4IIE cells, a rat hepatocyte-derived cell line and in rats. Cell viability was significantly reduced in Cd-treated H4IIE cells in a time and concentration-dependent manner. However, Crataegii Fructus water extract (CFE) protected the cells from Cd-induced cytotoxicity via inhibition of PARP cleavage. To induce acute toxicity in rats, Cd (4 mg/kg body weight) was dissolved in normal saline and intravenously injected into rats. The rats then received either a vehicle or silymarin (as a positive control) or CFE (50, 100 mg/kg/day) for 3 days, and were subsequently exposed to a single injection of Cd. Alanine aminotransferase (ALT), aspartate aminotransferase (AST) and lactate dehydrogenase (LDH) were significantly increased by Cd treatment. In contrast, pretreatment with CFE reduced ALT, AST and LDH. In histopathological analysis, CFE reduced the hepatic degenerative regions and the number of degenerative hepatocytes. These are considered as direct evidences that Crataegii Fructus has favorable inhibitory effects on the Cd-intoxicated liver damages. The efficacy of Crataegii Fructus shows slight lower than that of silymarin in the present study.

  • We plan to make the standardization of the pattern identifications for stroke and differentiate them by tongue diagnosis. We make a case report form which has questionnaires for tongue diagnosis in stroke patients. And we collected cases from the multi center network which consists of twelve university hospitals and one local hospital. The cases confirmed by diagnosis of medical specialists and residents are 321 cases. They are divided into Qi Defficiency 30.84%, Dampness& Phlegm 25.55%, Fire & Heat 22.43%, Eum Defficiency 18.69% and Blood Stasis 2.49%. We analyzed the markers which classified into the color of tongue body, the color of fur, the quality of fur, the dryness of tongue, the shape of tongue. To make a stroke pattern identification standard, we must try variable ways.

  • This study is to develop a standard tool for pattern identifications in Korean Medicine for Lung Cancer. The advisor committee for this study was organized by 12 Korean Medicine professors from the Korean Association of Traditional Oncology. The item and structure of instrument were based on review of published literature. We took the consultation twice from the advisor committee and additional advices by e-mail correspondences. We divided the symptoms and signs of lung cancer into 6 pattern identifications. - lung spleen both deficiency (肺脾兩虛), lung kidney both deficiency (肺腎兩虛), dampness phlegm obstructing the lung (濕痰蘊肺), qi stagnation blood stasis (氣滯血瘀), yin deficiency toxin heat (陰虛毒熱), and heat toxin accumulation (熱毒蘊結). We obtained the mean weights which reflected the standard deviations from each symptoms of the 6 pattern identifications which were scored on a 5-point scale by 12 experts. We designed the Korean medicine pattern identification tool for lung cancer. It was composed of 57 questions in the question-and-answer format. Though there are some limits that this study is not proved about validity and reliability, the instrument is meaningful and expected to be applied to the subsequent research.

  • This study draws pattern differentiations of headache disorders on the ground of modern clinical applications and Korean medical literature. Categorization and symptoms of headache disorders are based on International Classification of Headache Disorders 3rd edition(beta version). And clinical papers are searched in China Academic Journals(CAJ) of China National Knowledge Infrastructure(CNKI). In the aspect of eight principle pattern identification, primary headache occurs due to lots of yang qi and has more inner pattern rather than exterior pattern, heat pattern rather than cold pattern, excess pattern rather than deficiency pattern. And primary headache is related with liver in the aspect of visceral pattern identification and blood stasis, wind and phlegm are relevant mechanisms. Migraine without aura is associated with ascendant hyperactivity of liver yang, phlegm turbidity, sunken spleen qi, wind-heat, blood deficiency or yin deficiency. Migraine with aura is mainly related with wind and it's major mechanisms are ascendant hyperactivity of liver yang, liver fire, yin deficiency of liver and kidney, blood deficiency or liver depression and qi stagnation. High repetition rate of tension-type headache can be identified as heat pattern or excess pattern. And trigeminal autonomic cephalalgias can also be accepted as heat pattern or excess pattern when the occurrence frequency is high and is relevant to combined pattern with excess pattern of external contraction and deficiency pattern of internal damage based on facial symptoms by external contraction and nervous and anxious status by liver deficiency. This study can be expected to be Korean medical basis of clinical practice guidelines on headache by proposing pattern identifications corresponding to the western classifications of headache disorders.

  • The dried root of Angelica gigas (A. gigas) has been traditionally used as an oriental medicine, which is known to improve blood circulation and blood stasis. In the present study, leaves and stalks of A. gigas were used to investigate their effects on the innate immunity. The extracts were prepared from leaves and stalks of A. gigas and were fed to mice. The numbers of blood cells, total WBCs, neutrophils, lymphocytes, eosinophils and basophils were increased by 50% in mice fed with leaves extract of A. gigas compared to control mice. However, the numbers of blood cells were decreased when treated with stalks extract of A. gigas. The level of cholesterol and triglyceride in serum was markedly reduced in both mice group fed with leaves extract and stalks extract of A. gigas compared to control group (P<0.01). There was no significant change in the level of albumin, total protein, phosphate and calcium in serum. Activity of cationic peptide was found to be diffused in the testicles of mice fed with leaves extract of A. gigas compared to control group, which might be due to increased lysozyme in testicle. The lysoplate assay and immunohistochemistry assay suggest that the extract of leaves and stalks of A. gigas are immunogenic, but the effects might be related with acquired immune response rather than innate immunity.
