Cudrania tricuspidata has been used for a long time as a traditional herb medicine in Korea nad China. This paper has shown the experimental results about the physiological activities of water-, ethanol-, ethyl acetate-soluble fractions from ethanolic extracts of leaves, stems and roots of Cudrania tricuspidata. The effects of these fractions on the growth of various cells have exhibited that the ethyl acetate fractions from leaves, stems and roots inhibited significantly the growths of macrophage(RAW 264.7 cell), melanoma cell(B16-F10 cell), fibroblast cell(CCD-986sk cell), and lung carcinoma cell(A549 cell). The water and ethanol fractions of leaves and ethanol fraction of stems demonstrated better antioxidant activities scavenging radicals than other fractions when compared with the concentrations of different fractions for scavenging free radical DPPH (di(phenyl)-(2,4,6-trinitrophenyl) iminoazanium).

As concentration of ADP was increased, the rate of phosphocreatine formation by respiring heart mitochondria was increased. The value of apparent Km of the phosphocreatine-forming mitochondria for ADP was estimated to be 0.0185 mM. This value was much lower than that of Km for ATP (0.31 mM) which was determined from the reaction of the soluble form of mitochondrial creatine kinase. The concentration of ATP remained constant during the respiring in the presence of ADP. The rate of accumulation of oxidative-phosphorylated ATP in the mitochondrial respiration medium was continuously monitored as a function of ADP concentration with the firefly luciferase-coupled assay. In that case, exogenous creatine did not affect the rate of accumulation of ATP, indicating that phosphocreatine-forming (i.e.,respiring) mitochondria in the presence of ADP did not use the ATP in the medium as a substrate.These results suggest that the heart mitochondrial creatine kinase bound to the inner membrane functionally tight-coupled to the oxidative phosphorylating system with respect to the respired ATP.

Detection of parallelism by a compiler is very desirable from a user's point of view. However, even the most sophisticated techniques to detect parallelism trip on trivial impediments, such as conditionals, function calls, and input/output statements, fail to detect most of the parallelism present in a program. Some parallelizing compilers provide feedback to the user when they have difficulty in deciding about parallel execution. Under these circumstances, a programmer has to restructure the source code to aid the detection of parallelism. But, functional and declarative languages can be said to offer many advantages in this context. Functional programs are easier to reason about because their output is determinate, that is, independent of the order of evaluation. However, functional languages traditionally have lacked good facilities for manipulating arrays and matrices. In this paper, a declarative language called Id has been proposed as a solution to some of these problems.

Three kinds of plant fermentation broths and one liquor were prepared using persimmon, Ulmus davidiana var. japonica and barley, and investigated its physiological functionality. Anti-aging antioxidants activity was the highest of 99% in Ulmus dacidiana bar. japonica liquor and also was high in the persimmon vinegar(68.3 %). SOD-like activity show also 80.6% in the Ulmus davidiana var japonica liquor however the other fermentation broths were less 25%. Antihypertensive angiotensin I-converting enzyme inhibitory activity and fibrinolytic activity were weak or not detected in all the fermentation broths. Anti-dementia acetylcholinesterase inhibitory activity were showed 54.7% in the Ulmus davidiana var. japonica liquor. Our results showed that the Ulmus davidana var. japonica liquor has the potential to become a new functional liquor because of high antioxidant activity and anti-dementia activity.

Eight species of the family Bithyniidae, Bithynia striatula, B. tentaculata, B. siamensis, B. leachi, B. kiusiuensis, B. misella, Bithynia sp. from Nepal, and Gabbia australis were studied for comparison of the radula structure by scanning electron microscope. Radular ribbons of B. siamensis and B. leachi had 60-70 rows, and the other species had 40-50 rows. Teeth of all species studied had symmetrical structure, i.e. a total of seven teeth (one central tooth, and one lateral and two pairs of marginal teeth on each side) in each row were observed. The basic tooth formula of eight bithyniids was 2:1:1:1:2. Numbers and shapes of cusps were slightly differ from individuals or species. The mesocone of the central tooth of B. striatula, B. tentaculata, B. siamensis and Bithynia sp. differed from those of the other species observed.

Background: Acute pyelonephritis (APN) is one of the most common community-acquired bacterial infections. Recent increases of antimicrobial resistance in urinary pathogens might have changed the other epidemiologic characteristics of APN. The objective of this study was to describe the current epidemiology of APN in Korea, using the entire population. Methods: From the claims database of the Health Insurance Review and Assessment Service in Korea, the patients with International Classification of Diseases, 10th Revision codes N10 (acute tubulo-interstitial nephritis) or N12 (tubulo-interstitial nephritis, neither acute nor chronic) as the primary discharge diagnosis during 2010-2014 were analyzed, with two or more claims during a 14-day period considered as a single episode. Results: The annual incidence rate of APN per 10,000 persons was 39.1 and was on the increase year to year (35.6 in 2010; 36.7 in 2011; 38.9 in 2012; 40.1 in 2013; 43.8 in 2014, P = 0.004). The increasing trend was observed in both inpatients (P = 0.014) and outpatients (P = 0.004); in both men (P = 0.042) and women (P = 0.003); and those aged under 55 years (P = 0.014) and 55 years or higher (P = 0.003). Eleven times more women were diagnosed and treated with APN than men (men vs. women, 6.5 vs. 71.3), and one of every 4.1 patients was hospitalized (inpatients vs. outpatients, 9.6 vs. 29.4). The recurrence rate was 15.8%, and the median duration from a sporadic episode (i.e., no episode in the preceding 12 months) to the first recurrence was 44 days. The recurrence probability increased with the number of previous recurrences. The average medical cost per inpatient episode was USD 1,144, which was 12.9 times higher than that per outpatient episode (USD 89). Conclusion: The epidemiology of APN in Korea has been changing with an increasing incidence rate.

From January, 1994 to January. 1996, mitral valve replacement was performed in 27 patients. Among these, 17 patients underwent mitral valve replacement(MVR) with preservation of the annulo-papillary continuity(PAPCMVR) (-Group I), and 10 patients underwent conventional methods of excision of all the chordae(Group II). The operative technique for PAPCM VR consists of the division of the anterior leaflet into anterior and posterior segments, shifting and reattachment of the divided segments to the mitral ring of the respective commissural areas. This retrospective study has been designed to evalute the postoperative left ventricular function in the two groups. In the group 1, LVEF(Left Vnetricular Ejection Fraction : %) was 52 $\pm$ 3 preoperatively And 50$\pm$3 postoperatively, LVESI Vent icular End Systolic Volume Index/mL/m2) wIns 59 :6 and 51 $\pm$ 7, LVEDI Ventricular End Diastolic Volume Index/mL/m2) was 124$\pm$ 11 and 91 :8. In the group II, LVEF was 56$\pm$1 and 47:), LVESVI 62$\pm$12 and 61$\pm$15, LVEDVI 133$\pm$27 and 104$\pm$17. : the variation of the LVEF in these two group was statistically different(p(0.05). A comparison of left ventricular function data between Group I(n: 17) and Group II(n: 10) revealed better results in echocardiographic LVEF(p<0.05), LVEDVI(p<0.01) in the former group. The mean functional class(UYHA) was 2.6 preoperative and improved to 1.0 postoperatively In group 1, and 2.8 and to 1.0 in group II. We conclude that maintenance of continuity between the mitral annulus and papillary muscles is expected to have a beneficial effect on postoperative left ventricular performance.

Helicobacter pylori infection is highly prevalent, as high as 2/3 of whole population infected, in Korea. H. pylori infection initiates inflammation by induction of interleukin-8 through type IV secretion of CagA. It was recently suggested that induction failure of IL-8 is not associated with defect in cag PAI but associated with cagE locus diversity. This study was designed to investigate ability of 11-8 in-duction according to sequence variation within the cagE gene, cagA TP motifs and vacA m-types in vitro study using AGS cell-line, and to evaluate its association with different clinical outcome. Seventy-four H. pylori stains were isolated from 23 patients with gastric cancer (Ca), 24 subjects with gastritis (G) and 27 patients with duodenal ulcer (Du) in Kangnam St. Mary's Hospital, Seoul, Korea. cagE gene diversity was confirmed by the PCR-RFLP methods with MboI/NlaIII and tyrosine phosphate motifs (TPMs) of cagA was determined TPM-A and C by using DdeI/Tsp5091 restriction enzyme and TPM-B was determend by Real time PCR the method of Owen et al. and IL-8 was measured by ELISA assay. IL-8 activity was positively detected in 59 among 74 strains $(79.7\%)$. IL-8 secretion was significantly increased in MboI A and MboI B type compared to MboI C type and in MboI/NlaIII A-C and B-C type than C-C type. 1L-8 activity was not associated with either the number or composition of cagA tyrosine phosphorylation motifs and vacA m-type. There was no significant difference in IL-8 activity among patient groups. cagE gene diversity is thought to be mainly associated with the induction of IL-8 in H. pylori infection.
