Objectives : This study was done to assess the effects of the clinical interchange between the Western Medicine and the Oriental Medicine for ischemic stroke patients. The patient outcomes include changes in neurologic function by modified NIH stoke scale, stroke pattern identification scale, and patient satisfaction, Methods : For the assessment of effects, this study was performed with 178 inpatients who had undergone the stroke care at three hospitals (W Hospital adopted western therapy, S Oriental Hospital adopted Sasang constitution medicine therapy, and H Oriental Hospital adopted mixed therapy according to a joint protocol on Western Oriental medical care) from November 1997 to December 1998. Patients were interviewed or written with self-entered questionnaire forms, and clinical data were obtained, Physicians or oriental doctors wrote clinical questionnaire forms according to the care process. Results : The patient outcomes within three hospitals at 2 stages (at admission and discharge in the modified NIH stroke scale. at admission and second weeks during admission in the stroke pattern identification scale) were found to be decreased, Especially in the results of hierarchical multiple regression analysis, the degree of improvement of modified NIH stroke scale of the stroke patients at W Hospital was significant large than it at S Oriental Hospital. Also, the degree of improvement of stroke pattern identification scale at W Hospital was significantly large than it at other two hospitals. However, the patient's satisfaction score at three hospitals wasn't significantly different. Conclusions : The result of this study suggested that the joint clinical research of Western & Oriental medical practitioners was possible even if there was a conflict between Western Medicine and Oriental Medicine. Therefore Western & Oriental medical practitioners share a mutual responsibility to apply evidence-based practice, to seek scientific empirical proof through randomized clinical trials between the multicenter.

To develop low endotoxic and multi-immunogenic outer membrane vesicles (OMVs), a deletion mutant of the msbB gene in Salmonella enterica serovar Typhimurium (S. Typhimurium) was used as a source of low endotoxic OMV, and an expression vector of the canine parvovirus (CPV) VP2 epitope fused to the bacterial OmpA protein was constructed and transformed into the Salmonella ${\Delta}msbB$ mutant. In a lethality test, BALB/c mice injected intraperitoneally with the Salmonella ${\Delta}msbB$ mutant survived for 7 days, whereas mice injected intraperitoneally with the wild type survived for 3 days. Moreover, all mice inoculated orally with the ${\Delta}msbB$ mutant survived for 30 days, but 80% of mice inoculated orally with the wild type survived. The OmpA::CPV VP2 epitope fusion protein was expressed successfully and associated with the outer membrane and OMV fractions from the mutant S. Typhimurium transformed with the fusion protein-expressing vector. In immunogenicity tests, sera obtained from the mice immunized with either the Salmonella msbB mutant or its OMVs containing the OmpA::CPV VP2 epitope showed bactericidal activities against wild-type S. Typhimurium and contained specific antibodies to the CPV VP2 epitope. In the hemagglutination inhibition (HI) assay as a measurement of CPV-neutralizing activity in the immune sera, there was an 8-fold increase of HI titer in the OMV-immunized group compared with the control. These results suggested that the CPV-neutralizing antibody response was raised by immunization with OMV containing the OmpA::CPV VP2 epitope, as well as the protective immune response against S. Typhimurium in BALB/c mice.

This study was performed to investigate the average molecular weight range of chitosan hydrolysates showing maximum effect in macrophage activation. Nitrite production by continuous macrophage cell line J774A.1 was the highest at $10\;{\mu}g/ml$ concentration of intact chitosan. Hydrogen peroxide production by J774A.1 showed the high value of $894\;{\mu}M/mg$ macrophage protein at $1,000\;{\mu}g/ml$ concentration of chitosan hydrolysate fraction 5 and $1,044\;{\mu}M/mg$ macrophage protein at $100\;{\mu}g/ml$ concentration of the fraction 6. Chitsan hydrolysate fraction 4, fraction 6 and intact chitosan enhanced $IL-1{\alpha}$ production, while the others did not. The production of tumor necrosis factor showed the high value at $1,000\;{\mu}g/ml$ concentration of chitosan hydrolysate fraction 4, $100\;{\mu}g/ml$ concentration of the fraction 5 and fraction 6, and $10\;{\mu}g/ml$ concentration of intact chitosan. In conclusion, fractions 4, 5 and 6 of the chitosan hydrolysatets with average molecular weight of $24,000{\sim}64,000$ calculated by HPLC analysis are the most effective in macrophage activation tested in this study.

In order to ascertain latitudinal variation of lipid contents and compositions in copepods, we collected warm water copepod species (Euchaeta sp. and Pleuromamma spp.) from four different regions from low (sub-tropical) to mid (temperate) latitudes in the Northwest Pacific Ocean. Total lipid contents of Pleuromamma spp. were about 11 $ug{\cdot}ind^{-1}$ with little latitudinal variation, whereas Euchaeta sp. showed slightly higher lipid content (20 $ug{\cdot}ind^{-1}$) than Pleuromamma spp. with latitudinal gradient (low at subtropic and high at temperate). Wax esters, known as the major storage lipid classes, were found to be the dominant lipid classes (accounting for more than 35% of total lipids) in Euchaeta sp., whereas in Pleuromamma spp., phospholipids, known as cellular membrane components, were the dominant lipid classes. However, the exception was specimens from warm pool region exhibiting dominance in storage of lipids as a form of triacylglycerols. Among fatty acids, polyunsaturated fatty acids (PUFA), especially docosahexaenoic acid (DHA : 22:6(n-3)) (about 35% of total fatty acids), were most abundant in Euchaeta sp., while saturated fatty acids (SAFA), specially hexadecanoic acid (16:0) (about 30% of total fatty acids), were most abundant in Pleuromamma spp.. Among the neutral fraction of lipids, phytol, originated from the side chain of chlorophyll, was found in all samples which generally indicate active copepods feeding on algae. While only trace amounts of short-chain fatty alcohols were found in Pleuromamma spp., significant amounts of fatty alcohols were found in Euchaeta sp.. Particularly, significant amounts of long chain monounsaturated fatty alcohols (20:1 and 22:1), generally found in cold water species, were found in Euchaeta sp. from low latitudes. The latitudinal variation of trophic lipid markers in these copepods could be significantly related with in-situ food availability and species-specific diet preference. The result of this study suggests that the lipid contents and compositions in copepods may not only indicate their nutritional condition and feeding ecology but also provide insight into species-specific living strategies under different environmental conditions (i.e. water temperature, food availability).

The purpose of this article is to investigate the effects of cash flow and accrual, which are the elements of earnings, and those of the elements of cash flow and accrual on the consistency of cash flow and firm's value. We analyzed 4 kinds of regression models, of which the independent variables are this period's cash flow, the elements of cash flow, accrual, and the elements of accrual, and the dependent variables are the next period's cash flow, and the stock price at the end of financial statements disclosure months, respectively. The sample firms were the manufacturing companies listed on the Stock Exchange 1980 through 2006, of which the fiscal year ended in December. And, the results of the analyses are as follows: Cash flow and accrual are shown to have significant relationships with cash flow consistency and the evaluations of firms' value. And, the elements of cash flow or accrual proved to have more influence than the total amount of them, on cash flow consistency and the evaluation of firms' value. Also, the results present that some of the elements of cash flow and accrual differently affect cash flow consistency and the evaluation of firms' value. Accordingly, this study indicates that each of the elements of cash flow and accrual needs to be considered respectively rather than the total amount of them, in the case that cash flow and accrual are used in the decision-making concerned with the forecast of cash flow and the evaluation of firms' value. This study also shows that each element of cash flow and accrual needs to be used differently for cash flow forecast and the evaluation of firms' value.

In Sasang constitutional medicine, I have researched the process of visceral structure in the Eight Constitutionals under circulation of the five elements and the formation of primary source of illness. From this research, I could draw following conclusions through combination of the auxiliary psycho-formulas by applying the constitutional acupuncture therapy on the five elements diagnostic calculation. Since the arrangement for the five dimensions of organs in the eight constitutions has been formulated by circulation of the five elements in Sasang constitutions, if the five elements begin circulating count-clockwise from the reference point at the organs in Sasang constitutional medicine, the positive constitutional arrangement of organs is built up such as, the positive constitution of metal, earth, wood and water, while begin circulating clockwise, the negative constitutional arrangement of organs is formulated, such as the negative constitutions of metal, earth, wood and water. The source of illness results from imbalance of the organic force being generated by transfer of the five elements from compatibility to incompatibility when the five elements circulate. Hence, it has been acknowledged that if the source of illness comes from the strongest organ, it is the time when circulation of the five elements progresses from the second organ (the second strongest) in incompatibility, and if the source of illness comes from the weakest organ, it is the time when circulation of the five elements progresses from the third organ (the middle) in incompatibility. It is considered proper to diagnose meridians of the pericardium and the Triple Burners rather than to diagnose meridians of the heart and the small intestine which forms the visceral arrangement of the eight constitutions. For instance, the auxiliary psycho-formula obtains its prescription by attenuating the first organ (the strongest) while augmenting the fourth organ (the second weakest) when the axis of incompatibility in the five elements circulation crosses the second and the third organs, and it gets its prescription by attenuating the second organ(the second strongest) while augmenting the fifth organ(the weakest) when the axis of incompatibility in the five elements circulation crosses the third and the fourth organs. In addition, when medicating, the $4{\sim}5$ times of repeated performance can be assumed to represent the amount of an energy that each organ bears depending on the phase in the arrangement of the eight constitutional organs.
