  • Objectives: This study describes how two patients diagnosed with type-II diabetes mellitus were successfully treated using herbal medicine. Methods: The patients were given Yuldahanso-tang to reduce the effects of Taeumin's dry-febrile symptom. Results: Type-II diabetes mellitus symptoms experienced by patients with Taeumin's dry-febrile symptom included thirst, fatigue, weight loss, and numbness in the hands and feet. After administering Yuldahanso-tang, all numerical levels for blood sugar, glycated hemoglobin (HbA1c), glycosuria, and proteinuria recovered to within normal levels. Conclusions: Treatment of patients with Taeumin's dry-febrile symptom and type-II diabetes mellitus with Yuldahanso-tang was effective, and this new evidence supports the use of herbal medicine for treating such patients.

  • Genetic selection and sophisticated management technology have produced modern sows which excel in litter size and milk production. Recent research has identified nutritional innovations which may enhance productivity of the high producing sow. Selected research in three areas which have the potential to enhance reproductive performance are summarized in this report. First, preliminary evidence indicates that organic chromium may enhance litter size and conception rate. Secondly, high producing sows, particularly primiparous sows, required higher protein/lysine in late gestation and or lactation to optimize weaning weight and subsequent litter size. Valine and isoleucine, but not leucine, have been shown to enhance milk production. Phased feeding programs with diet cost partitioned toward gilts and away form parity 3 to 8 sows have been suggested as a means of improving reproductive performance in young sows. Lastly, recent research with sufficient sow numbers to document the effect of dietary fiber on reproductive performance has shown that sows fed fiber farrowed and weaned more pigs.

  • The low molecular weight zinc-binding protein metallothionein (MT) contains 32% cysteine and has been shown to efficiently scavenge hydroxyl radicals in vitro. MT expression is induced by oxidative stress and an antioxidant role for this protein has therefore been proposed. This review mainly focuses on the evidence for this role arising from studies using genetically modified animals and cells which either over-or under-express MT. Despite some considerable disparity of results in the literature, reported studies do generally support an antioxidant role. Nevertheless, oxidant stress at non-physiological treatment levels has been the preferred experimental model and there is little information about the role of MT in physiological oxidative stress Although it is presumed that the mechanism by which MT has an antioxidant effect involves oxidation of cysteinal thiols, it is possible that zinc release from MT is in itself an important signalling factor.

  • In survival analysis of observational data, the inverse probability weighting method and the Cox proportional hazards model are widely used when estimating the causal effects of multiple-valued treatment. In this paper, the two kinds of weights have been examined in the inverse probability weighting method. We explain the reason why the stabilized weight is more appropriate when an inverse probability weighting method using the generalized propensity score is applied. We also emphasize that a marginal hazard ratio and the conditional hazard ratio should be distinguished when defining the hazard ratio as a treatment effect under the Cox proportional hazards model. A simulation study based on real data is conducted to provide concrete numerical evidence.

  • The minimum disparity estimators introduced by Lindsay and Basu (1994) are studied empirically. An extensive simulation in this paper provides a location estimate of the small sample and supplies empirical evidence of the estimator performance for the univariate contaminated normal model. Empirical results show that the minimum generalized negative exponential disparity estimator (MGNEDE) obtains high efficiency for small sample sizes and dominates the maximum likelihood estimator (MLE) and the minimum blended weight Hellinger distance estimator (MBWHDE) with respect to efficiency at the contaminated model.

  • In humans, an immediate allergic response to an allergen snay appear as either bronchial asthma unaccompanied by anaphylaxis or a severe bronchial constriction and spasm accompanied by anaphylaxis. Much experimental evidence with isolated asthmatic tissues has shown that histamine is released during the allergic reaction. Paradoxically, antihistamine treatment is ineffective in reversing bronchial asthma or anapllylaxis in a man. The present study objective is to search for protective agents(In-Sam-Yun-Pai-San-Ga-Gam-Bang) against bronchial constriction in treating a anaphylaxis. The result from this study is as follows. A single dose of In-Sam-Yun-Pai-San-Ga-Gam-Bang extract(3ml/kg body weight) 2 hrs prior to histamine-induced bronchial constriction test demonstrated significant protection. Based on the above result, It is considered that In-Sam-Yun-Pai-San-Ga-Gam-Bang can be used in bronchial asthma.

  • Background: The emergence of new infectious diseases threatens public health, increasing socioeconomic damage, and national risks. This study aimed to develop an evidence-based risk assessment tool to quickly respond to new infectious diseases. Methods: The risk elements were extracted by reviewing the risk assessment methods of the World Health Organization, United States, Europe, United Kingdom, and Germany, and the validity and priority of elements were determined through expert meetings and Delphi surveys. Then, the scale and level for each risk element were defined and a final score calculation method according to the risk evaluation result was derived. The developed risk assessment tool was verified using data at the time of domestic transmission of an emerging infectious disease. Results: In case of spread of actual infectious diseases, priority is determined based on the criticality of the elements in each area of transmissibility and severity, from which the weighted score of the risk assessment is derived. Then, the risk score for each element was calculated by multiplying the average value of the risk evaluation by its weight and the evaluation risk assessment score for the two areas was calculated. At last, the final score is plotted in a matrix where the x-axis indicates the transmissibility and the y-axis the severity and plotted on the coordinate plane for time series use. Conclusion: With respect to transmissibility and severity, this risk assessment method to respond to new and re-emerging infectious diseases enables rapid and evidence-based evaluation by quantitatively and qualitatively assessing various risk elements.

  • Background Clinical practice guidelines (CPG) are systematically developed statements to assist practitioners and patients on healthcare decisions. They provide recommendations for the average patient, which should take into account individual clinical judgment and the patient's values and expectations. Ephedra has sympathomimetic effect and has been used for weight loss worldwide. However, its safety is controversial especially in autonomic and cardiovascular systems. Therefore, the need of appropriate CPG for ephedra prescription in obesity was advocated in Korean Traditional Medicine. Methods The committee comprised of specialists of obesity, oriental herbology, oriental cardiology, constitutional medicine. The committee collected all relevant references about adverse effect and safety of ephedra in the forms of meta-analysis, systematic review, randomized controlled trial, case-control study and observational study from international and domestic databases and paper journals. 11 English- and 5 Korean-language references were gathered and categorized by PICO (Patient, Intervention, Comparison, Outcome) method. We could not complete strength of recommendation which should be clarified according to the evidence grade estimation. Result The first version of CPG for ephedra prescription in obesity was issued by Korean Oriental Association for Study of Obesity. It includes topics of introduction, pharmacokinetics, side effects and adverse events, constitutional aspect and recommendations for dose, indication and contraindication. Conclusion There should be periodic upgrade of this CPG from now on. Although there are some drawbacks in this version of CPG, it has significance as the first CPG in Korean Traditional Medicine.
