Objectives: Systems related to the production, authorization, and listing for insurance of herbal medicine products were compared between South Korea and Taiwan to illuminate herbal medicine products system issues in South Korea. Methods: Papers, and laws and policies related to the production, authorization, and listing for insurance of herbal medicine products in South Korea and Taiwan are analyzed to create the primary documents. The documents from South Korea were screened with the advice of a specialist, while those from Taiwan have been verified through local investigation and with the help of a related specialist. The screened documents were then compared and analyzed in the order of the systems related to the production, authorization, and listing for insurance of herbal medicine products. Results: The systems related to the production of herbal medicine products satisfy GMP requirements in both countries, while Taiwan has more specialized systems related to the production of herbal medicine products and a more strict authorization program as compared to South Korea. While South Korea has most of the herbal medicine products classified as non-prescription drugs, Taiwan has them as prescription drugs. And while South Korea does not allow new herbal medicine products to be listed for insurance, Taiwan allows for once-a-year application toward listing for insurance. Conclusions: In order to ensure the safe and effective use of herbal medicine products, systems related to the production, authorization, and listing for insurance of herbal medicine products are to be established, while the categorization of medicine products principally used by Korean medicine doctors should be prepared. Furthermore, prescription by a Korean medicine doctor for new drugs made with natural products and their listing for insurance need to be encouraged.

Purpose: There is an issue in applying various principles introduced in established Korean medical classics to "Pharmaceuticals Approval, Notification and Review" of "herbal medicinal preparations" and "new drugs from natural products" that are used for western forms of medical treatment. Thus, an analysis of the origin, purpose, and application of established Korean medical classics in the Korean Pharmaceutical Affairs Act is essential. Methods: We collected data regarding the origin, purpose, and application of established Korean medical classics in the Korean Pharmaceutical Affairs Act, and classified them by periodical change and subjects. Results: Established Korean medical classics are applied as follows: 1) as criteria for Korean medicine distributors' sales of mixed herbal drugs (Pharmaceutical Affairs Act; since 1953), 2) as official compendiums for pharmacists' preparation of Korean medicine (Ministry of Health and Welfare's authoritative interpretation; from early 1970s to 1993), 3) as standards for oriental pharmacists' quality measurement of preparations (notification of the Ministry of Health and Welfare; since 1995), 4) as criteria for "Pharmaceuticals Approval, Notification and Review" of herbal medicinal preparations and crude drug preparations (notifications regarding drug approval process by the Ministry of Health and Welfare and the Ministry of Food and Drug Safety; since 1978), and 5) as standards for the quality of materials of health functional food (from 2004 to 2011). Conclusion: The application of Korean medical classics has been closely related with the change of the laws, regulations, and systems that are relevant to Korean medicine, and it seems to be more favorable for pharmacists than oriental pharmacists. Meanwhile, regulations that apply prescriptions that are recorded in Korean medical classics - dosage, indications, and preparation methods - as criteria for the approval of crude drug preparations for western medical treatment should be abolished.

Background: The aim of the study was to determine the prevalence of shisha smoking and associated factors among medical students in Malaysia. Materials and Methods: A cross-sectional study was conducted at the Management and Science University from December 2011 until March 2012. The questionnaire consisted of five sections including socio-demographic, social environment, knowledge about shisha, psychosocial factors, and personal shisha smoking behavior. Obtained data were analyzed using Statistical Package for the Social Sciences (SPSS 13). T-test was used to determine the relationships between shisha smoking and socio-demographic characteristic. Results: A total number of 300 medical students participated in this study. Mean age was $22.5{\pm}2.5$ years. The majority were female, Malay, single, from urban areas (67%, 54%, 97%, 73%; respectively). The prevalence of shisha smoking among medical students was found to be 20%. The study revealed that many students believed that shisha does not contains nicotine, carbon monoxide, does not lead to lung cancer, dental problems and does not lead to cardiovascular diseases (25%, 20.7%, 22.3%, 29%, 26.7%; respectively). Age and sex were found to be significantly associated with smoking shisha status among medical students (p=0.029, p<0.001; respectively). Furthermore, having parents, siblings and friends smokers of shisha were found to be significantly associated with shisha smoking status (p<0.001, p<0.001, p<0.001; respectively). Furthermore, family problems, problems with friends, financial problems and university life were found to significantly associated with shisha smoking status among medical students (p<0.001, p=0.002, p<0.001, p=0.002; respectively). Conclusions: There is a high prevalence of shisha smoking and a poor knowledge about its impact on health among medical students. More attention is needed to focus on medical education in this regard. The policies that are currently employed in order to reduce the cigarettes smoking should be applied to shisha smoking and shisha products.

Ghrelin and obestatin are a single gene products and are a multiple functional peptides that regulates energy homeostasis, and food intake. In the present work, we studied the secretion of ghrelin and its co-secreted peptide obestatin in 44 patients with ischemic heart disease with that of 27 healthy matched controls. Here we first conducted using an immunohistochemistry assay to screen whether human salivary glands have any obestatin immunoreactivity. Then, serum and saliva obestatin and acylated ghrelin levels were determined by using Radioimmunoassay. Our immunohistochemical analysis demonstrated that obestatin was localized in the striated and excretory duct of human salivary gland. We also report for the first time that obestatin, like ghrelin, is present in human salivary gland and saliva. No evidence of the role of obestatin or ghrelin saliva levels in the context of ischemic heart disease was found. Salivary ghrelin and obestatin levels are correlated in controls with the blood levels. Determination of salivary values could represent a non-invasive alternative to serum ones that can be useful in clinical practice.

Background: The continuing growth of the ethanol industry has generated large amounts of various distillers grains co-products. These are characterized by a wide variation in chemical composition and ruminal degradability. Therefore, their precise formulation in the ruminant diet requires the systematic evaluation of their degradation profiles in the rumen. Methods: Three distillers grains plus soluble co-products (DDGS) namely, corn DDGS, high-protein corn DDGS (HP-DDGS), and wheat DDGS, were subjected to an in situ trial to determine the degradation kinetics of the dry matter (DM) and crude protein (CP). Soybean meal (SBM), a feed with highly degradable protein in the rumen, was included as the fourth feed. The four feeds were incubated in duplicate at each time point in the rumen of three ruminally cannulated Hanwoo cattle for 1, 2, 4, 6, 8, 12, 24, and 48 h. Results: Wheat DDGS had the highest filterable and soluble A fraction of its DM (37.2 %), but the lowest degradable B (49.5 %; P < 0.001) and an undegradable C fraction (13.3 %; P < 0.001). The filterable and soluble A fraction of CP was greatest with wheat DDGS, intermediate with corn DDGS, and lowest with HP-DDGS and SBM; however, the undegradable C fraction of CP was the greatest with HP-DDGS (41.2 %), intermediate with corn DDGS (2.7 %), and lowest with wheat DDGS and SMB (average 4.3 %). The degradation rate of degradable B fraction ($%\;h^{-1}$) was ranked from highest to lowest as follows for 1) DM: SBM (13.3), wheat DDGS (9.1), and corn DDGS and HP-DDGS (average 5.2); 2) CP: SBM (17.6), wheat DDGS (11.6), and corn DDGS and HP-DDGS (average 4.4). The in situ effective degradability of CP, assuming a passage rate of $0.06h^{-1}$, was the highest (P < 0.001) for SBM (73.9 %) and wheat DDGS (71.2 %), intermediate for corn DDGS (42.5 %), and the lowest for HP-DDGS (28.6 %), which suggests that corn DDGS and HP-DDGS are a good source of undegraded intake protein for ruminants. Conclusions: This study provided a comparative estimate of ruminal DM and CP degradation characteristics for three DDGS co-products and SBM, which might be useful for their inclusion in the diet according to the ruminally undegraded to degraded intake protein ratio.

The interactions between the host and microbial pathogen largely dictate the onset, progression, and outcome of infectious diseases. Pathogens subvert host components to promote their pathogenesis and, among these, cell surface heparan sulfate proteoglycans are exploited by many pathogens for their initial attachment and subsequent cellular entry. The ability to interact with heparan sulfate proteoglycans is widespread among viruses, bacteria, and parasites. Certain pathogens also use heparan sulfate proteoglycans to evade host defense mechanisms. These findings suggest that heparan sulfate proteoglycans are critical in microbial pathogenesis, and that heparan sulfate proteoglycan-pathogen interactions are potential targets for novel prophylactic and therapeutic approaches.

Understanding of trafficking, processing, and degradation mechanisms of amyloid precursor protein (APP) is important because APP can be processed to produce β-amyloid (Aβ), a key pathogenic molecule in Alzheimer's disease (AD). Here, we found that APP contains KFERQ motif at its C-terminus, a consensus sequence for chaperone-mediated autophagy (CMA) or microautophagy which are another types of autophagy for degradation of pathogenic molecules in neurodegenerative diseases. Deletion of KFERQ in APP increased C-terminal fragments (CTFs) and secreted N-terminal fragments of APP and kept it away from lysosomes. KFERQ deletion did not abolish the interaction of APP or its cleaved products with heat shock cognate protein 70 (Hsc70), a protein necessary for CMA or microautophagy. These findings suggest that KFERQ motif is important for normal processing and degradation of APP to preclude the accumulation of APP-CTFs although it may not be important for CMA or microautophagy.
