  • Samyoyongantang (SMY), a herbal medicine, has been used as cure for gangrene. To evaluate anti-inflammatory effect of samyoyongantang, we treated samyoyongantang extract in animal model system induced contact hypersensitivity. Contact hypersensitivity, a local inflammatory response of the skin, was induced by 1% DNCB on the right ear of BALB/c mouse. Samyoyongantang was prepared as water extract and administrated everyday for 2 weeks per oral. A right ear of mouse was potently swelled by 1% of DNCB treatm ent, but a mouse ear thickness was significantly reduced by samyoyongantang after 2 we eks treatment. Samyoyongantang reduced IgG in serum obtained from blood of 1 % DNCB-treated mouse. IgE in serum was not changed by samyoyongantang treatment. From these results, anti-inflammatory effect of samyoyongantang, especially reduction of ear swell ing, might be partly due to reduction of IgG in serum.

  • Recently, food industries are increasingly interested in launching ethnic foods in the global market, but communicating sensory information to target consumers has been complicated due to the ambiguity and complexity of Korean sensory descriptors. This study was conducted to elicit various multidimensional sensory descriptors and their definitions using focus group interviews (FGI). Two consumer groups, consisting of 10 panelists in their 20s and 10 panelists in their 30-40s respectively, participated in the FGI. A total of 14 commonly used multidimensional sensory descriptors, including gamchilmat (감칠맛), gaeun (개운), goso (고소), gusu (구수), kkal-kkeum (깔끔), neu-kki (느끼), dambaek (담백), birin (비린), siwon (시원), sikeum (시큼), ssapssarae (쌉싸래), eolkeun (얼큰), jjapjoreum (짭조름), and kalkal (칼칼), were elicited. Their definitions showed that these descriptors not only were constructed using several sensory elements but also contained hedonic connotations. Descriptors such as gaeun, siwon, and kkal-kkeum were more closely associated with overall sensory impressions, including aftersensations and post-ingestive effects rather than sensory concepts. As individuals tend to weigh different elements to construct the concept for each multidimensional descriptor, further studies are required to identify elements consisting of these descriptors to develop better test methods and gain a clearer understanding of the sensory profiles of Korean foods.

  • BACKGROUND: After transplanting, the recent abnormal low temperature caused physiological disorders of pepper seedlings. This study was conducted to evaluate the effects of UV-A LED, a physical elicitor, on the chilling tolerance of pepper seedlings. METHODS AND RESULTS: Seedlings were continuously irradiated with 370 and 385 nm UV-A LEDs with 30 W·m-2 for 6 d. After that, seedlings were exposed to 4℃ for 6 h and then recovered under the normal growing condition for 2 d. There were no significant differences in growth characteristics of UV-A treatments compared to the control. Fv/Fm values of two UV-A treatments were below 0.8. Electrolyte leakage in the control was increased by chilling stress, while 385 nm UV-A had the significantly lowest value. Total phenolic content and antioxidant capacity of two UV-A treatments significantly increased due to UV-A radiation. However, total phenolic content and antioxidant capacity of the control increased due to chilling stress and tended to decrease again during the recovery time. CONCLUSION: We confirmed that UV-A light was effective to induce the chilling tolerance of pepper seedling, and the supplemental radiation of 385 nm UV-A LED before transplanting could be used as a cultivation technique to produce high quality pepper seedlings.

  • The primary purpose of this study was to provide the basic materials for C.V.A inpatients' actual use of medical service at the hospital with both the western and oriental medical department and the attitude on cooperative treatment. The results of this study were as follow: First, the subjects' general characteristics including job, monthly mean income and age made statistical differences to their pathological characteristics such as part of primary paralysis, detailed name of disease and cause of elicitation. Second, their general characteristics including religion and job produce statistical difference to their actual use of medical service, like medical institution form, term of treatment and type of medical institution at first-aid. Third, through the awareness of cooperative treatment system, the effect of C.V.A treatment and the shorten of the C.V.A treatment term were higher at oriental medical department inpatients and cooperative treatment serviced inpatients than western medical department inpatients and cooperative treatment non-serviced inpatients. Fourth, the biggest problem on current dual medical system is increase medical expenses and the biggest reason on not vitalized cooperative service is prejudice of both parts.

  • It is well known that bacterial lipopolysaccharide (LPS) stimulates the prostaglandin (PG) synthesis in various experimental system, but the mechanism and the detailed nature of its action are yet to be understood. Thus, this study was designed to characterize LPS induced PG synthesis in rat alveolar macrophage. Although results were not so much prominent, LPS stimulated PGE2 synthesis in macrophage with short term exposure, and this was thought to be mainly due to the activation of phopholipase A2+ But there was a burst in the PG synthesis 6 hours after the LPS treatment and this was accompanied with the increase of cyclooxygenase activity. This effect was not mediated by tumor necrosis factor (TNF) or platelet activating factor (PAF), and the existence of serum was prerequisite for its action. Growth factors such as epidermal growth factor (EGF) and platelet derived growth factor (PDGF) themselves did not stimulate PG synthesis and the showed stimulatory activities to some extent. Normal rat serum was more effective for the elicitation of the LPS action than growth factors. Thus, considering the amounts of growth fafctors contained in normal serum, it was suggested that another factors like LPS binding protein (LBP) might be involved in the serum effect on LPS action. Conclusively. it was thought that LPS could stimulate PG synthesis through interaction with serum factors such as EGF, PDGF and/or LBP.
