The catch by the set net fishery from 1971 to 1985 were analyzed in order to reveal its fluctuation characteristics. Generally, the catch increased from 16,787M/T in 1971 to 84,103M/T in 1985 and showed maximum in 1979 with 99,475M/T of catch. This trend was mainly related to the higher production of file fish which accounts for 64% of the total catch in 1979, and the change of catch statistical classification according to the revising of fishery law in 1976. It was also closely related to the variation of the sea water temperature in coastal area. The main fishing period of the set net fishery appeared from October to November. Catch of the set net fishery was led by that in the southern coast before 1976 and by that in the eastern coast from 1977 to 1980, the tendency changed irregular from 1981. Three groups of fishes could be distinguished by principal component analysis of the annual catch. A group showing steady decreasing tendency was composed of the fishes such as whiting, sand fish, hair tail and anchovy. The another group composed of small alaska pollack, round herring, goby, gizzard shad, sand lance and file fish revaled an increasing tendency. The other fishes did not show any annual tendency.

Background: Pilomatrixoma is a benign tumor that originates from the hair follicle matrix. It usually presents as a hard, slow growing, solitary mass that can be easily misdiagnosed as other skin masses. The aim of this study was to clinically analyze a case series of pilomatrixoma in pediatric patients from Korea. Methods: A total of 165 pediatric patients from 2011 to 2018 with a histological diagnosis of pilomatrixoma were included. A retrospective review was performed using the electronic medical records, including patient demographics, number and location of the mass, clinical and imaging presentation, and postoperative outcomes. Results: There were 61 male and 104 female patients with 152 solitary and 13 multiple pilomatrixomas. Among solitary pilomatrixomas, the lesion commonly occurred in the head and neck (84.2%), followed by upper limbs (11.2%), lower limbs (3.3%), and trunk (1.3%). The pilomatrixoma lesion presented as the following types based on our clinical classification: mass (56.02%), pigmentation (25.31%), mixed (12.65%), ulceration (4.82%), and keloid-like (1.2%). Ultrasonography showed a high positive predictive value (95.56%). There were no specific complications observed except for two cases of recurrence. Conclusion: Pilomatrixoma has various clinical feature presentations and commonly occurs in the head and neck. Ultrasonography is a helpful diagnostic tool. Surgical removal of the lesion is the main treatment method with a low recurrence rate.

The purpose of this study was to determine the effect of microamperage electrical stimulation on the number of argyrophilic nucleolar organizer region (AgNOR) in rat skin. Twenty four male Sprague-Dawley rats were divided into electrical stimulation and control group. Bach animals hair on the back was removed. The electrical stimulation group received an positive rectangular positive electrical stimulation with $500{\mu}A$, while the control group was given the same treatment without electricity. The rats were sacrificed at 4 and 7 day of stimulation, respectively. The biopsy specimens were fixed in formalin, embedded in paraffin and stained with silver nitrate. The AgNOR were counted using a light microscope and computerized image analysis system and calculated as the mean number of AgNOR per nucleus in the epidermal keratinocyte. In control skin, the mean AgNOR count of epidermal keratinocyte at 4 and 7 day were 1.67 and 1.72, whereas electrical stimulated rat had mean AgNOR counts of 2.0 and 2.14, respectively. A Student's t-test showed a significantly higher mean AgNOR number at 4 ana 7 day in the electrical stimulated rats than control rats (p<0.05). The microamperage electric current stimulation increased the epidermal AgMOR expression in incisional wound skin. These results suggest that the microamperage electrical stimulation may promote migration and proliferative activity of epidermal keratinocyte in surgical wound.

This study investigated the proximate compositions and sensory attributes of fresh and boiled soybean sprouts. The sensory attributes of cooked soybean sprouts (Kongnamulmuchim) were also assessed after boiling and seasoning. Proximate compositions were analyzed from the total sprout, cotyledon and hypocotyl without hair root. Soybean sprouts cultivated with four recommended soybean cultivars (Nokchae bean, Dawon bean, Seonam bean and Pungsannamul bean) in a lab and then used for analysis. Carbohydrate, protein, lipid and ash contents were lower, while moisture was lower, in the cotyledon than in the hypocotyl of fresh soybean sprouts, regardless of the bean type. Each soybean sprout showed different contents of chemical constituents in total sprout, cotyledon, and hypocotyl parts. Sensory attributes such as odor, flavor, and overall acceptability were evaluated. Each panels showed a response on a 9-point rating scale. The acceptability of fresh soybean sprouts was negatively correlated with beany and grassy tastes, but positively correlated with nutty and sweet tastes. The acceptability of boiled soybean sprouts was negatively correlated with beany and grassy flavors, and positively correlated with nutty odor and flavor. In addition, acceptability of cooked soybean sprouts (Kongnamulmuchim) was positively correlated with nutty and sweet flavors. The beany and grassy flavors limited acceptability of fresh soybean sprouts, whereas the prominence of nutty flavor might contribute to acceptance of boiled and cooked soybean sprouts.

Dlx3 is a homeodomain protein and is known to play a role in development and differentiation of many tissues. Deletion of four base pairs in DLX3 (NT3198) is causally related to tricho-dento-osseous (TDO) syndrome (OMIM #190320), a genetic disorder manifested by taurodontism, hair abnormalities, and increased bone density in the cranium. The molecular mechanisms that explain the phenotypic characteristics of TDO syndrome have not been clearly determined. In this study, we examined phenotypic characteristics of wild type DLX3(wtDlx3) and 4-BP DEL DLX3 (TDO mtDlx3) in C2C12 cells. To investigate how wtDlx3 and TDO mtDlx3 differentially regulate osteoblastic differentiation, reporter assays were performed by using luciferase reporters containing the promoters of alkaline phosphatase, bone sialoprotein or osteocalcin. Both wtDlx3 and TDO mtDlx3 enhanced significantly all the reporter activities but the effect of mtDlx3 was much weaker than that of wtDlx3. In spite of these differences in reporter activity, electrophoretic mobility shift assay showed that both wtDlx3 and TDO mtDlx3 formed similar amounts of DNA binding complexes with Dlx3 binding consensus sequence or with ALP promoter oligonucleotide bearing the Dlx3 binding core sequence. TDO mtDlx3 exhibits a longer half-life than wtDlx3 and it corresponds to PESTfind analysis result showing that potential PEST sequence was missed in carboxy terminal of TDO mtDlx3. In addition, co-immunoprecipitation demonstrated that TDO mtDlx3 binds to Msx2 more strongly than wtDlx3. Taken together, though TDO mtDlx3 acted as a weaker transcriptional activator than wtDlx3 in osteoblastic cells, there is possibility that during in vivo osteoblast differentiation TDO mtDlx3 may antagonize transcriptional repressor activity of Msx2 more effectively and for longer period than wtDlx3, resulting in enhancement of osteoblast differentiation.

Medicinal plants containing wellness-fusion-complex compound are increasingly being pursued as suitable alternative sources of various biological properties. In this study, inhibitory effect of Quintinia acutifolia, which is a New Zealand plant, on P388 murine lymphocytic leukemia cells using MTT [3-(4,5-dimethylthiazol-2-yl)- 2,5-diphenyl-tetrazolium bromide] assay. Based on $^1H-NMR$, $^{13}C-NMR$ spectral data and other spectral analysis, 2,3,2'',3''-tetrahydroochanaflavone (1) and 2'',3''-dihydroochana-flavone (3) inhibited the leukemia cells were purified from the plants. 2,3,2'',3''-tetrahydroochanaflavone (1) and 2'',3''-dihydroochana-flavone (3) are biflavonoids possessing two basic flavonoids and actively inhibited growth of P388 murine lymphocytic leukemia cells with a 50% inhibitory concentration ($IC_{50}$) of $8.2{\mu}g/mL$ and $3.1{\mu}g/mL$, respectively. Specially, 2'',3''-dihydroochana-flavone (3) possessed unconjugated flavonone system, which isn't consist of a pair with B ring of 2,3,2'',3''-tetrahydroochanaflavone (1). Therefore, the two compounds could be considered as a candidate for development of anticancer drugs and need to much studies in the future.

It was determined whether the sandwich ELISA using specific anti-CP4 EPSPS polyclonal and monoclonal antibodies, developed in the previous study, could be applied to detect GM soybean or not. The soybeans (47 imported and 20 domestic soybeans) were analyzed by a sandwich ELISA. The results of imported soybeans were divided into two groups which were high contents $(39.1{\pm}13.5\;{\mu}g/g,\;n=33)$ and low contents of CP4 EPSPS $(2.6{\pm}1.2\;{\mu}g/g,\;n=14)$. The ratio of GM in imported soybeans was about 70.2%. One the other hand, the contents of CP4 EPSPS in domestic soybeans was very low $(0.9{\pm}0.5\;{\mu}g/g,\;n=20)$ which determined to be non-GM soybeans. In case of soybean sprouts, the contents of CP4 EPSPS in soybean sprouts were different between GM and non-GM soybean sprout. The CP4 EPSPS in cotyledon of GM soybeans sprout was higher than that in root hair. The contents of CP4 EPSPS in soybeans sprout of domestic soybeans were very low. Thus, it was possible to determine that the soybeans sprout was made of GM or non-GM soybeans. Also, PCR experiment showed that the sandwich ELISA was accurate to distinguish the soybeans to be GM or non-GM. These results showed the sandwich ELISA could determine the soybeans were GM or non-GM, rapidly and simply.
