  • Background : Since March 2009, when the first patient of novel influenza A (H1N1) was reported, many deaths have occurred in North and Central America. The start of the 2009 influenza pandemic was declared by WHO Director-General Dr. Margaret Chan on 11 June 2009, and the level of influenza pandemic alert raised from phase 5 to phase 6. There was no vaccine yet developed, and many experts worried that the novel H1N1 virus could kill as many or more as did the influenza pandemic in 1918-1919. Objective : To evaluate the possibility of treatment for 2009 novel influenza A (H1N1) using herbal remedies and other non-conventional therapies. Methods : We researched the clinical studies for novel H1N1 influenza virus-related herbal medicine or non-conventional medicine treatment using internet search engines including PubMed and CNKI. In addition, we reviewed many reports and clinical practice guidelines (CPG) for influenza A (H1N1). Results : Two case series were selected after reviewing 701 papers, and two CPG published by the Chinese government and Jilin province identified. They reported that the clinical symptoms were no more significant than seasonal influenza, and the condition of patients more than 45 years old was milder than those less than 45 years old. There are no patients with gastric problems, and oseltamivir has been used at the same time in all patients. Conclusion : The efficacy and effectiveness of herbal medicine and other non-conventional treatments for the novel influenza A (H1N1) is questionable, and more studies are needed to draw a firm conclusion. However, in the severe acute respiratory syndrome (SARS) experience in 2002/2003, it was demonstrated that herbal medicine can relieve all symptoms of SARS patients, promote absorption of lung inflammation, improve the degree of blood oxygen saturation, regulate immunological functions, reduce the required dosage of glucocorticoid and other medicines, and reduce case fatality rate. In light of the current situation that there is no vaccine or conventional treatment yet available, the study of herbal medicine and other non-conventional therapies are also necessary for appropriate evaluation.

  • Objective: In the winter of 2002, severe acute respiratory syndrome(SARS) began to spread throughout the world. More than 5,000 cases were reported in China, including over 1,700 cases in Hong Kong Special Administrative Region(Hong Kong SAR). The total number of cases reported from Canada and Singapore was more than 200. The total number of SARS cases world-wide reached 8,437 with incidences in 29 counties. Mortality from SARS is estimated at $10{\sim}12%$. When the SARS outbreak occurred in China, the State Administration of Traditional Chinese Medicine of China immediately initiated clinical research projects on the use of integrated herbal medicine and Western medicine for treating SARS. and, in Hong Kong SAR, research on the use of herbal medicine for the prevention and treatment of SARS. Reports were released during convalescence. The objective of this study is to overview twelve clinical SARS reports of WHO on the treatment of SARS with herbal medicine and evaluate the efficacy and safety of treatment of SARS with herbal medicine, and further to share experiences and knowledge of the treatment of SARS. Methods: Twelve clinical reports about SARS from the WHO were selected, overviewed and evaluated for efficacy and safety of treatments of SARS. Results and Conclusion: Twelve clinical reports about SARS showed that the integrated treatment may have advantages, and the advantages are reflected in the following findings: Firstly, herbal medicine is not targeted only at a specific etiology or a certain pathological link, but also at the pathological status of the patients at that particular time. Therefore, comprehensive readjustment was made through various angles, targets and channels to restore the balance of the body. Secondly, there are advantages in the differentiation of the disease and the treatment. Based on the various symptoms, herbal medicine enables the physician to adopt the most suitable principle, provide individual treatment, and to administer medicine in accordance with the actual process and nature of the illness. Thirdly, there are advantages in the results of the treatment; herbal medicine can relieve symptoms, promote absorption of lung inflammation, improve the degree of blood oxygen saturation, regulate immunological functions, reduce the required dosage of glucocorticoid and other Western medicines, and reduce case fatality rate, in addition to lowering the cost of treatment.

  • Chinese herb medicines have traditionally been used to treat or alleviate the symptom of various diseases. The rationale for use of certain herbs to certain disorder is now getting unveiled by modern technology. In the present study, we investigated whether herb mix extract(HMX), which is alleged to be useful for gastric ulcer, protects stomach from oxidative stress. Rats were allowed to normal diet with and without HMX (1, 5, 10 mg/kg) for 30 days. To induce gastric ulcer, ethanol (75%, 1.5 ml) or acidified aspirin (100 mg/kg in 0.2 N HCl) was administered by oral route in 24 h-fasted rats and examined the gastric ulceration(bleeding) by measuring the size 1 h after the treatment. Results indicated the area of gastric bleeding was significantly less in HMX fed rats than in normal diet fed ones, and it was dependent on the duration and amount of HMX. To investigate the underlying mechanism by which HMX protects stomach from oxidative stress, expression of enzymes like heme oxygenase (HO), cyclooxygenase (COX), and inducible nitric oxide (iNOS) were investigated in MKN-74 cells, where aspirin or H. pylori was introduced. The results were compared with RAW 264.7 cells to check if there's cell specificities exist. The expression of HO-1 but not COX-2, iNOS was significantly increased by HMX. Furthermore, HO-1 inhibitor, SnPP IX reduced the HO-1 activity and reversed the survival rate in HMX-treated MKN-74 cells. There's no difference between RAW 264.7 cells and MKN-74 cells. We, thus, concluded that HMX is beneficial for protection from oxidative injury, and induction of HO-1 by HMX in gastric cells is, at least, responsible for protection from oxidative stress such as ethanol, aspirin and possibly H. pylori infection.

  • In the course of a study for the development of functional foods utilizing Woosul (Achyranthis radix), the components and various biological activities of Korean Woosul (AJN: Achyranthes japonica Nakai) and Chinese Woosul (ABB: Achyranthes bidentata Blume) were compared. Woosul in Korea, including AJN and ABB, are regulated and part of the Korean Pharmacopoeia. From AJN and ABB, ethanol extracts and their subsequent organic solvent fractions were prepared and their in-vitro antimicrobial, antioxidant and anti-diabetes activities were evaluated. Although AJN and ABB have no clear distinction in terms of usage in Korea, our results suggest that AJN has higher quantities of lipid-soluble components and lower amounts of water-soluble sugars than does ABB. ABB also appears to possess greater amounts of flavonoid and polyphenol substances than AJN. Analyses of biological activities showed that the fractions of AJN were more active as antibacterial agents, and possessed more pronounced ${\alpha}$-glucosidase inhibitory activities than those of the ABB fractions. However, the antioxidant activities of the ABB fractions, as determined by DPPH anion-, ABTS cation-, nitrite-scavenging activity and reducing power, were higher than those of the AJN fractions. Our results suggest that the components and bioactivity of the extracts and subsequent fractions of AJN and ABB are different. Therefore, usage of either AJN or ABB should be carefully considered, as regards their individual properties, when the active fractions of Woosul are employed in the development of functional foods or novel plant-derived medicines.

  • Phomopsis sp. XP-8 (an endophytic fungus) was previously found to produce pinoresinol diglucoside (PDG), a major antihypertensive compound of Tu-Chung (the bark of Eucommia ulmoides Oliv.), which is widely used in Chinese traditional medicines. In the present study, two bioconversion systems were developed for the production of PDG in Tris-HCl buffer containing glucose and Phomopsis sp. XP-8 cells (both resting and freeze-dried). When other factors remained unchanged, the bioconversion time, glucose concentration, cell ages, cell dosage, pH, temperature, and stirring speed influenced PDG production in a similar and decreasing manner after an initial increase with increasing levels for each factor. Considering the simultaneous change of various factors, the optimal conditions for PDG production were established as 70 g/l cells (8-day-old), 14 g/l glucose, $28^{\circ}C$, pH 7.5, and 180 rpm for systems employing resting cells, and 3.87 g/l cells, 14.67 g/l glucose, $28^{\circ}C$, pH 7.5, and 180 rpm for systems employing freeze-dried cells. The systems employing freeze-dried cells showed lower peak PDG production ($110.28{\mu}g/l$), but at a much shorter time (12.65 h) compared with resting cells (23.62 mg/l, 91.5 h). The specific PDG production levels were 1.92 and $24{\mu}g$ per gram cells per gram glucose for freeze-dried cells and resting cells, respectively. Both systems indicated a new and potentially efficient way to produce PDG independent of microbial cell growth.

  • Objectives: This study aimed to learn what should be considered in the Guidelines of Clinical Trials with Herbal Medicinal Products for Gastroesophageal Reflux Disease (GERD) by analyzing the existing guidelines and clinical trials.Methods: The development committee searched the existing guidelines for herbal medicinal products or GERD. Then, clinical trials related to GERD using herbal medicine were selected. The chosen trials were analyzed in terms of their inclusion and exclusion of participants, intervention, comparators, outcome, and trial design. Then, we compared the results of the analysis according to the regulations and guidelines of the Ministry of Food and Drug Safety to suggest the issues that we will have to consider when developing the Guidelines of Clinical Trials with Herbal Medicinal Products for Gastroesophageal Reflux Disease (GERD).Results: As a result, few guidelines for GERD and clinical trials with herbal medicinal products were located in the national institution homepage. In addition, 8 articles were found using the following combination of search terms: “Gastroesophageal reflux disease”, “GERD”, “herbal medicine”, “herbal therapy”, “Korean Medicine”, “Traditional Chinese Medicine”, and “TCM”. Even though all trials had their own unique research questions, all studies were performed using a randomization method. Most trials included participants with reflux esophagitis, but two trials targeted proton pump inhibitor-refractory GERD. The type of intervention varied, such as decoction, granules, and capsules. Additionally, individualized herbal medicines were used in two studies. Comparators were diverse, such as placebo, Western medicine, and electro-acupuncture. The most frequently used outcome for efficacy was the effectiveness rate. In addition, the outcome for evaluating quality of life, esophageal mucosa and pressure, esophageal acid reflux, and recurrence rates were used. Safety was investigated by recording adverse events and carrying out laboratory tests.Conclusions: We identified some issues by reviewing the existing guidelines and comparing them with clinical trials for GERD and herbal medicinal products. These results will be utilized for developing the Guidelines of Clinical Trials with Herbal Medicinal Products for Gastroesophageal Reflux Disease (GERD).

  • Objective: The objective of this study was to explore the knowledge and perceptions of Malaysian tradition healers towards cancer and cancer prevention. Methodology: A total of 25 participants agreed to participate in this qualitative study during the period from $20^{th}$ July 2011 until $24^{th}$ of September 2011. The proposal of this study was approved by the Ethics Committee of Management and Science University (MSU). Once the participant agreed to be interviewed, date, time and place of the interviews were determined. Consent form was obtained from participants before the interview began. Participants were briefed about the study and its purpose, and after asking their permissions, their replies were recorded. The data was organized into themes and analyzed manually. Results: Twenty-five Malaysian traditional healers participated in this qualitative study. The age of participants ranged between 26 to 78 years old. The majority were in the age group of 31-60 years old, male, Chinese, degree holders with a monthly income ranging from 1,000-5,000 Ringgit Malaysia (RM) and were married (56%, 80%, 48%, 52%, 68%, 84% respectively). The majority defined cancer as having high cholesterol or abscess accumulation. A few of them defined cancer as a type of cell growth. The majority mentioned that food and unhealthy lifestyles are the primary causes of cancer. Surprisingly some of them mentioned that cancer is caused by interference by ghosts. Regarding the diagnosis of cancer, the majority mentioned that they refer their patients to modern physicians' medical report when it comes to diagnosing or treating patients with cancer. The most common cancers that many patients came to seek treatment were breast cancers, followed by colon cancers, liver and lung cancers. Conclusions: Despite good knowledgeabout the causes of cancer among traditional healers, misconceptions still exist. Insufficient knowledge about the definition of cancer was noted among the traditional healers. This urges immediate action by the Ministry of Health of Malaysia to set up a strict regulation and regular monitoring of the traditional healers nationally. Traditional and Complementary Medicine may be integrated into the healthcare system and need to have sustained cooperation for the benefit of patients since about 80% of patients use traditional medicines.

  • Recently, the occurrence and death rates of cancer have increased rapidly. Metastasis and recurrence is the most important factor of death from cancer. So inhibition of recurrence and metastasis can increase the cure rate of cancer disease. At the basic chinese traditional medicine(TCM), there are a lot of theory related to neoplasm treatment. The metastasis and recurrence of neoplasm was the basis of yudu(餘毒) on remained neoplasm cell and stagnation of blood, thermotoxo, phlegm, asthenia of healthy enerngy and stagnation of vital energy. The principles therapy of neoplasm on metastasis and recurrence was based on knowledge of the method of support the healthy energy and strengthen the body resistance, promote blood circulation to remove blood stasis, clear away heat and toxic materials, dissipate phlegm and disperse the accumulation of evils. But the major clinical features of neoplasm was to be considered in developing a treatment plan include (1) distinguish between clinical and pathologic staging - acute and chronic, (2) classification of pathologic pattern, and (3) distingction of body situation : for examples asthenia - sthenia etc. It was most important to distinguish between supporting the healthy and eliminating the evil factors and to treat differently at the root and the branch cause of a neoplasm. This paper's results indicate that identification and effective use of THM can inhibite netastasis and recurrence and then it will help increasing survival rate. Also as BioTechnology(BT) has developed rapidly nowadays, as genes related to cancer have revealed. So it will give rise to the development of searching the mechanism of herb medicines which have inhibition effects of metastasis and recurrence.

  • Objective : Herb medicines are potential sources of useful edible and medicinal plants. They are used as a drug because of their various biological activities such as immunomodulatory, antiviral, and antitumor functions. Nelumbo nucifera have been applied in Chinese herbal prescriptions to improve tissue inflammation. However, it has not been elucidated on the effect of the flower of Nelumbo nucifera in cells. Method : In the present study, to examine the effect of that on glioma cells, U87, the essential oil was extracted from the flower of Nelumbo nucifera (NN essential oil). U87 cells were exposed to different concentrations of 2-40 ug/ml of NN essential oil in ethanol. Cell viability was measured by MTT assay at 24 h. To find out the intracellular target signal molecule(s) for this antiproliferative activity of NN essential oil, phosphorylation of Akt, ERM, MAPK or p38 proteins were examined by Western blot analysis. To study long term effect of NN essential oil in U87 cells, the image of cells treated with NN essential oil for 4 days were obtained. Results and Conclusion : NN essential oil was shown to exhibit antitumor activity in glioma cells, at a broad range of concentrations of 10-40 ug/ml. The phosphorylation of Akt and Endoplasmic Reticulum Matrix (ERM) proteins which known to be involved in the cell death, were gradually decreased to 2 hours after addition 20 ug/ml of NN essential oil. However, the phosphorylation of mitogen-activated protein (MAPK) and p38 was found to increase in NN essential oil treated cells. NN essential oil treated cells showed decreased glioma cell number. These results provide a possible NN essential oil-induced inhibitory signal for tumor cell proliferation that is initiated by the decrease in Akt activity. Moreover, it is likely that the activation of p38 is required for the NN essential oil-induced inhibition of tumor proliferation.

  • In order to investigate the radioprotective effect of Si-Wu-Tang (Korean name: Sa-Mul-Tang), a kind of traditional Oriental medicine as a blood-building decoction (Oriental medical concept: Bu-Xie), and Si-Jun-Zi-Tang (Korean name: Sa-Gun-Ja-Tang), one of the widely used Oriental herbal medicines as an energy tonic (Chinese medical concept: Bu-Qi). the jejunal crypt survival, endogenous spleen colony formation, and apoptosis in jejunal crypt cells were observed in irradiated mice. Jejunal crypts were protected by Si-Wu-Tang pretreated both per os (2 mg/mL of drinking water for 7 days, p<0.05) and intraperitoneally (1 mg/head, single injection at 24 hours before irradiation). Si-Wu-Tang adminstration before irradiation(1 mg/head, single injection at 24 hours before irradiation) resulted in an increase of the formation of endogenous spleen colony (p<0.005). The frequency of radiation-induced apoptosis in intestinal crypt cells was also reduced by pretreatment of Si-Wu-Tang (p<0.01). However, the radioprotective effect of Si-Jun-Zi-Tang was not as significant as that of Si-Wu-Tang. These results suggest that Si-Wu-Tang may be a useful radioprotective food, especially since it is a relatively nontoxic natural product.
