  • Colorectal carcinoma is one of the four major cancers in Korea, and it shows the tendency of increase every year due to economic development and changes to western styles. Accordingly, various diagnostic methods are needed and so comparative genomic hybridization (CGH) was performed. Deletion was detected on 5q (10%), 10q (17%), 17p (40%), 18p (23%), 18q (47%), 22q (23%), and higher deletion loci were 18q (12/30, 47%), 17p (12/30, 40%), and 22q (7/30, 23%). Amplification was shown on chromosomes 6pq (10%), 7p (17%), 7q (33%), 8q (13%), 9pq (10%), 12q (17%), 13q (37%), 20p (23%), and 20q (57%) respectively. The highest amplification was detected on chromosomes 20q (17/30, 57%), 13q (11/30, 37%), and 7q (10/30, 33%). The genetic change pattern with the locus of colorectal carcinoma was shown mean 3.1 (amplification 1.7, deletion 1.4) on the right colorectal carcinoma, while rectal carcinoma appeared high mean 6.3 (amplification 3.7, deletion 2.6) (p<0.001). The genetic change pattern with lymphatic gland metastasis, mean 3.5 (amplification 2.2, deletion 1.3) from "no metastasis" group, while high mean 6.3 (amplification 3.5, deletion 2.8) from metastasis group (p<0.003). The genetic change pattern with disease stages appeared mean 3.5 (amplification 2.1, deletion 1.4) from I-II stages, while high mean 6.0 (amplification 3.4, deletion 2.6) from III-IV stages (p<0.006). No significance was observed in comparing histological classification and serum CEA increased groups.

  • The role of vascular NAD(P)H oxidase in subarachnoid hemorrhage (SAH)-induced vasospasm in the basilar artery was examined in a rat model. Arterial vasospasm characterized by increased wall thickness and decreased lumen size was observed at 5 to 7 days after $2^{nd}$ injection of blood into cisterna magna, and these changes were significantly ameliorated by pretreatment of diphenyleneiodonium $(DPI,\;25\;{\mu}l\;of\;100\;{\mu}M),$ an inhibitor of NAD(P)H oxidase. To determine the time course of changes in the vascular NAD(P)H oxidase activity, cerebral vasculature was isolated at different time intervals from 12 hrs to 14 days after injection of autologous blood. At 24 hrs after the second injection of blood, the NAD(P)H oxidase activity was markedly increased with an enhanced membrane translocation of p47phox, but by 48 hours both the enzyme activity and p47phox translocation regained normal values, and were remained unchanged up to 14 days after SAH. However, no significant changes in the expression of p22phox mRNA was observed throughout the experiments. These findings suggest that the activation of NAD(P)H oxidase by which assembly of the oxidase components enhanced and subsequent production of superoxide in the early stages of SAH might contribute to the delayed cerebral vasospasm in SAH rats.

  • Methanol and hexane extracts from 35 species in 27 families of herbal plants were evaluated for their acaricidal activities against two-spotted spider mite, Tetranychus urticae by leaf-dipping and spraying methods in laboratory, pot and field, respectively. Acaricidal activities were different depending on herbal plants. When T. urticae was released on leaves of Phaseolus vulgaris var. humilis that were dipped in the 1,000 ppm hexane extracts from fruits of Torreya nucifer and Daphan genkwa, seeds of Xanthium strumarium and Pharbitis nil at one minute they experienced 56.8, 47.8, 47.7, and 47.7% mortalities, respectively. Dipping time influenced acaricidal activity, that is, one minute dipping was more effective than 30 second dipping of Phaseolus vulgaris var. humilis leaves. However, extracts of X. strumarium and P. nil seeds had comparatively high activities. Concentration of hexane extract of X. strumarium and P. nil seeds revealing LC50 were 1,824 and 1,899 ppm, respectively. Extracts of both plants from hot and cold water were not effective representing <20% mortality at 1,000 ppm. However, hexane extracts of X. strumarium and P. nil seeds were effective against T. urticae on P. vulgaris var. humilis representing 76.3 and 71.3% mortalities in pot, respectively. Control effects of hexane extract of P. nil seed were 50.8 and 35.1% at 2,000 and 1,000 ppm against T. urticae on Chrysanthemum morifolium in greenhouse, respectively.

  • Bombyx mori nucleopolyhedrovirus (BmNPV) orf47 gene was characterized for the first time. The coding sequence of Bm47 was amplified and subcloned into the prokaryotic expression vector pET-30a(+) in order to produce His-tagged fusion protein in the BL21 (DE3) cells. The His-Bm47 fusion protein was expressed efficiently after induction with IPTG. The purified fusion protein was used to immunize New Zealand white rabbits to prepare polyclonal antibody. As the genome of BmNPV is available in GenBank and the EST database of BmNPV is expanding, identification of novel genes of BmNPV was conceivable by data-mining techniques and bioinformatics tools. Structural bioinformatics approach to analyze the properties of Bm47 encodes protein.

  • Although healthy lifestyles have been proved as an effective way of improving higher well-beings for individuals. researches on health-promoting behaviors of minority elderly with a specific ethnic heritage have been sparsely tried. This study was designed to explore health-promoting lifestyle patterns of Korean immigrant elderly living in Seattle, USA and its relationships with two associated perceptual variables, self-esteem and perceived health status. One hundred ten Korean immigrant elderly were recruited from two senior centers and interviewed with a structured questionnaire. Data were collected from October 1998 to January 1999, and analyzed using SPSS program through which t-test, ANOVA, and Pearson Correlation Coefficients were tested. As the results, the mean HPLP score of the Korean immigrant elderly was 2.54 (SD = .36), showing significant differences by education (F = 3.61, P = .016), economic status (F = 3.01, P = .034), and current health status (F = 3.69, p = .008). In self-esteem, two socioeconomic variables showed statistical association with self-esteem : marital status (t = 2.47, P = .015) and living situation (F = 4.03, p = .021). The HPLP subscales that showed higher mean scores were nutrition (M = 3.01, SD = .52) and interpersonal support (M = 2.65, SD = .47) while lower mean scores were detected in the domain of exercise (M = 1.92, SD = .74) and stress management (M = 2.26, SD = .47). Perceived health status revealed significant positive correlation with health-promoting lifestyle patterns (r = .19, P = .043) and self-esteem (r = .32, P = .001) in the present study. It is concluded that engagement in health-promoting lifestyle patterns should be actively encouraged to enhance personal health of Korean immigrant elderly. Developing health promotion programs focused on exercise and stress management is also imperatively suggested not only for better health practices of Korean immigrant elderly population but also for enhancing their level of well-beings and life satisfaction.

  • This study was conducted to examine the nutrient digestibility and ruminal fermentation characteristics in sheep fed dried mugwort and mugwort silage for 5% levels of rice straw in the basal diet, and mugwort pellet for 5% levels of concentrate in the basal diet. For the experiment, they were given a basal diet containing of rice straw and concentrate mixed at a 3: 7 ratio (DM basis). The treatments were designed as a 4 ${\times}$ 4 Latin square design with four sheep (50.2 kg body weight). The digestibility of crude protein was increased (p < 0.05) to 4.6 - 6.2 % in sheep fed mugwort silage treatments (60.23 %) compared with those of control (54.08 %) and dried mugwort treatment (55.67 %). That of ether extract was iicreased (p < 0.05) to 4.8 - 8.8 % in sheep fed mugwort silage treatments (80.22 %) compared with those of control (71.47 %) and dried mugwort treatment (75.46 %). In the dry matter intake, mugwort silage treatment (904.44 g) was the hightest and mugwort pellet treatment, dried mugwort treatment and control were 810.66 g, 780.66 g and 742.18 g, respectively. The ruminal pH in all treatments were rapidly decreased (p < 0.05) at 0.5 and 1 hour after feeding and slowly increased at 2, 4 and 8 hours after feeding, especially mugwort silage treatment. The ammonia nitrogen concentrations were the highest (p < 0.05) in sheep fed mugwort silage treatment (11.24 - 12.05mg / 100 rnz) at 0.5 and 2 hours after feeding. The ruminal concentrations of acetic acid (6.06 mmol /100 $m\ell$) and propionic acid (2.35 mmol/ 100 mz) were an increased (p < 0.05) at the mugwort silage treatments at 1 and 2 hours after feeding. Purine derivatives out put (13.41 mmol / d) and microbial protein production (11.61 mmol / d) were increased (p < 0.05) compared with those of control (5.42 and 4.93 mmol / d).

  • This study was to examine the positive and negative affect related to psychological characteristics of each Sasang types using Positive and Negative Affect Schedule (PANAS) with 78 students from School of Korean Medicine, Pusan National University. After determining the Sasang types by QSCC II, the psychological characteristics of each Sasang types were analysed by PANAS. We did ANOVA analysis with eight related scales and found significant differences between the Tae-Eum type ($18.71{\pm}8.75$, $6.47{\pm}3.36$, $6.31{\pm}2.47$, $3.18{\pm}2.77$, $10.94{\pm}10.08$) and the So-Eum type ($13.38{\pm}6.03$, $4.55{\pm}2.23$, $4.19{\pm}2.16$, $5.81{\pm}4.20$, $1.83{\pm}9.17$, respectively) in Positive Affect (PA) (F=3.931, p=0.024), PA-Joy (F=3.991, p=0.023), PA-Interest (F=5.025, p=0.009), NA-Afraid (F=3.118, p=0.050), and Difference between Positive and Negative Affect (DPN) (F=6.355, p=0.003) scores. The post-hoc analysis showed that the Tae-Eum type ($18.71{\pm}8.75$, $6.47{\pm}3.36$, $6.31{\pm}2.47$, $10.94{\pm}10.08$) has significantly higher score than So-Eum type ($13.38{\pm}6.03$, $4.55{\pm}2.23$, $4.19{\pm}2.16$, $1.83{\pm}9.17$, respectively) in PA (p=0.018), PA-Joy (p=0.021), PA-Interest (p=0.017), and DPN (p=0.002) scores. The So-Eum type ($5.81{\pm}4.20$) showed significantly (p=0.047) higher score than the Tae-Eum type ($3.18{\pm}2.77$) in NA-Afraid. Results demonstrated distinct affect profile differences between Tae-Eum and So-Eum Sasang types using PANAS. This study may serve as the foundation in identifying psychological traits of Sasang types, especially regarding the aspect of affect.
