  • Kojongsi persimmon (Diospyros kaki) is the major cultivar of astringent persimmon in southern of Korea. Kojongsi persimmon leaf has been traditionally used for acute and chronic diseases in Oriental countries. The purpose of this study was undertaken to investigate the antioxidative activities of the extract of Kojongsi persimmon leaf during growth. We investigated the antioxidant effects of the persimmon leaf extracts during growth on total polyphenol, total flavonoid, electronic donating ability (DPPH), nitrite (NO) scavenging and superoxide dismutase (SOD)-like activity. The next, we investigated the possible cell protective effects of the persimmon extract treatment against ultraviolet B (UVB)-induced injury in HaCaT keratinocytes. The contents of total polyphenol and flavonoid in leaf extract of Kojongsi persimmon were increased in time-dependent manner. In Jun, DPPH and NO radical scavenging and SOD-like activities in the leaf extract of Kojongsi persimmon was increased to the highest. However, the antioxidant activities in persimmon varieties were not any difference. The cell cytotoxicity by UVB irradation in HaCaT keratinocytes was significantly increased with the compared to the control group. However, the treatment of leaf extract of Kojongsi persimmon in HaCaT keratinocytes was shown to protective effect against UVB-induced cell cytotoxicity. These results suggest that the leaf extract of Kojongsi persimmon has potent antioxidant activity, and protective effect against UVB-induced keratinocyte injury. Thus, these properties may be contributed in the care of acute and chronic diseases.

  • The regional distribution and relative frequency of endocrine cells in the GIT of the snakehead, Channa(Oph icephalus) argus were studied immunohistochemically. Five kinds of endocrine cells and one kind of nerve cell were identified in this study. A few numbers of secretin-immunoreactive cells were restricted to the cardia and fundus of the stomach. Moti-lin- and GRP-immunoreactive cells were rare in the epithelium of the distal and proximal intestines. PYY-immunoreactive cells were found in a few number in the pyloric caeca and were rare in the distal intestine. Substance P-immunoreactive cells were distributed relatively numerous from the fundus to the distal intetsine. Also, their nerve cells were detected in occurrence in the lamina propria in the distal intestine. No neurotensin-, met-Enk- and GIP-immunoreactive cells were found in the GIT of the snakehead.

  • Cirsium japonicum var. ussuriense are often used in treatment of human diseases such as hemorrhage, blood congestion and inflammation in Korea. However, there was not report on the anti-obesity efficacy of water extracts from different organs of C. japonicum var. ussuriense. Here, we investigated the antioxidant effects of water extracts of flowers, leaves and roots from C. japonicum var. ussuriense. Total polyphenol amounts of the flower extract showed higher than those of leaf and root extract. Flower extract also showed the high antioxidant activities such as DPPH radical scavenging activity and reducing power. We also investigated the anti-obesity effects of water extracts of flowers, leaves and roots from C. japonicum var. ussuriense in 3T3-L1 cells and high fat diet-induced obesity mice. The mice were divided into four groups [high fat diet (HFD) control, HFD + leaf extract, HFD + flower extract and root extract] and administered with each extract (200 mg/kg) for 12 weeks. The flower and leaf extract significantly suppressed the levels of oil red O and triglyceride content. The flower and leaf extract also significantly reduced the triglyceride, total cholesterol and lower density lipoprotein levels of plasma as well as body and abdominal fat weight. Furthermore, oral glucose tolerance in the flower and leaf extract groups were significantly ameliorated in comparison to the high fat diet group. Therefore, these results indicate that the flower and leaf extract could ameliorate obesity and attenuate blood glucose level in high fat diet-induced obesity mice. We conclude that this study may provide positive insights into water extracts of flowers and leaves from C. japonicum var. ussuriense as a functional food ingredient for treatment of obesity.

  • The spiritual world of the ancient times has precious values which forms the origin of human thought. This study aims to reevaluate ancient people's particular views on man in their spiritual world reflected through gods' ornaments by studying the human race's fundamental spiritual world gradually disappearing due to science development from Egyptian gods' ornaments expressed symbolically in Ancient mythical components. Although evidently ornaments in Egypt served for decoration, the basic purpose was exorcism as amulets, a shamanistic purpose to be protected from mystical and hostile powers by carrying them on the vulnerable spots of the body. As this aspect indicates, the human race tried to solve their self-insoluble transcendental issues through the help of supernatural power, pursuing to lead their lives there within. As a result, Egyptian ornaments; First, the deity raised their value by deifying human-beings. Second, the nobility enhanced their dignity by having goddesses wear the same skirts as theirs. Thirds, all deities maintained their class society by wearing fpassiums, bracelets, and anklets. Fourth, the resurrection was symbolized through gods and goddesses in charge of the afterlife.

  • Effects of glucocorticosteroids (GCS) on the thymus and peripheral lymphocytes of Nile tilapia. Oreochromis niloticus were examined. Young fish (5-7g) were injected into intraperitonial cavity with various dose of dexamethasone (DEX) or hydrocortisone (HC). Histology of thymus and thymocyte counts in treated fish were compared to normal ones. The results showed that in vivo adminstration of DEX or HC induced weight loss of thymus and reduction of thymocytes, and both of these were dose and time dependent. In vivo treatment of thymocytes with 10 mM DEX or 10 mM HC for 12hrs caused DNA fragmentation. Both drugs could split the DNA into fragments of about 180-200 base paire multiples. There was no change in granulocytes of peripheral blood due to the treatment of DEX or HC with various length of time. In contrast, treatment of DEX or HC for 2-3 days decresed number of peripheral lymphocytes. The results indicate that the thymocytes and circulating lymphocytes would respond to GCS depending on several factors, such as nature of the hormone, dose, and duration of treatment.
