  • Purpose: The purpose of this study was to examine the relationship between pigmental reaction and blood components, such as white blood cell (WBC), lymphocyte, monocyte, red blood cell (RBC), hemoglobin, mean corpuscular index (mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH) and mean corpuscular hemoglobin concentration (MCHC)), hematocrit, platelet and neutrophil segment, after Cupping Glass Therapy (CGT). Subjects: Twenty-five healthy adults participated in this study; Methods: Subjects had undergone CGT for 5 days and were divided into two groups (dark color (DCG) and light color (LCG)) depending the level of pigmental reaction. Blood was collected from each subject at the beginning of this study and recollected after 5 day s'CGT. Results: The percentage of lymphocytes was higher in LCG than in DCG after CGT (p<.01) and was significantly increased in LCD after CGT (p<.01), The number of RBC was more in DCG than in LCG both before (p<.01) and after CGT (p<.05). The amount of hemoglobin was more in DCG than in LCG both before (p<.01) and after CGT (p<.01) and was significantly increased in LCD after CGT (p<.01). Mean corpuscular index showed that both MCH (p<.05) and MCHC (p<.01) were higher in DCG than in LCG after CGT, but only MCHC before CGT (p<.01). It also showed either decreased MCV (p<.01) or increased MCHC in LCD after CGT (p<.01). Hematocrite was higher in DCG than in LCG both before (p<.01) and after CGT (p<.01). The percentage of neutrophil segments was higher in BCG than In LCG after CGT (p<.01) and was significantly decreased in LCD after CGT (p<.05). However, neither the number of WBC and platelets nor the percentage of monocytes was significantly different between DCG and LCG either before or after CGT. Conclusion: Pigmental reaction was significantly related to the changes of blood conponents after CGT. The results of this study suggest that CGT may have an effect on the components of blood cells.

  • Objectives : This study was carried out to investigate the effects of Ephedrae Herba pharmacopuncture (EHP) on the adipogenesis in 3T3-L1 cells, lipolysis in rat epididymal adipocytes and histological changes in porcine adipose tissue. Methods : Inhibition of preadipocyte differentiation and/or stimulation of lipolysis play important roles in reducing obesity. 3T3-L1 preadipocytes were differentiated with adipogenic reagents by incubating for 3 days in the absence or presence of EHP ranging from 0.01 to 1.0 $mg/m{\ell}$. The effect of EHP on adipogenesis was examined by measuring glycerol-3-phosphate dehydrogenase (GPDH) activity and by oil red O staining. Mature adipocytes from rat epididymal fat pad were incubated with EHP ranging from 0.01 to 1.0 $mg/m{\ell}$ for 3 days. The effect of EHP on lipolysis was examined by measuring free glycerol released. Fat tissue from porcine skin was injected with EHP ranging from 0.1 to 10.0 $mg/m{\ell}$ to examine the effect of EHP on histological changes under light microscopy. Results : The following results were obtained from present study on adipogenesis of preadipocytes, lipolysis of adipocytes and histological changes in fat tissue. Proliferation of preadipocytes was significantly inhibited by EHP at the concentration of 1.0 $mg/m{\ell}$. Lipolysis of adipocytes was increased by EHP at the concentration of 0.1, 1.0 $mg/m{\ell}$. Porcine fat tissues were widely injured by EHP at the concentration of 10.0 $mg/m{\ell}$. Conclusions : From the above results, EHP efficiently induces inhibition of preadipocytes proliferation, lipolysis of adipocytes and histologic injury in fat tissues. Therefore, EHP may be useful to treat localized obesity.

  • Carotenoids are synthesized from the plastidic glyceraldehyde-3-phosphate (GAP)/pyruvate pathway in isoprenoids biosynthetic system of plants. They play a crucial role in light harvesting, work as photoprotective agents in photosynthesis of nature, and are also responsible for the red, orange and yellow colors of fruits and flowers in plants. In addition to biological actions of carotenoids as antioxidants and natural pigments, they are essential components of human diet as a source of vitamin A. It has been also suggested that some kinds of carotenoids might provide protection against cancer and heart disease as human medicines. In this article, we review the commercial applications on the basis of biological functions of carotenoids, summarize the studies of genes involved in the carotenoid biosynthetic pathway, and introduce recent results achieved in metabolic engineering of carotenoids. This effort for understanding the carotenoids metabolism will make us to increase the total carotenoid contents of crop plants, direct the carotenoid biosynthetic machinery towards other useful carotenoids, and produce a new array of carotenoids by further metabolizing the new precursors that are created when one or two key enzymes in carotenoid biosynthetic pathway are exchanged through gene manipulation in the near future.

  • Hagfish Eptatretus burgeri is classified as a agnathans and has many different physiological properties compared with vertebrates. In this study, we examined effects of water temperature and salinity on blood properties and oxygen consumption in hagfish. In the experiment of water temperature change, hematocrit (Ht), red blood cell (RBC) and glucose of hagfish blood revealed the lowest values at $15^{\circ}C$. Oxygen consumption of hagfish had significantly increased with rising water temperature, and the increasing rate was twice as much when the temperature was manipulated every $5^{\circ}C$. Also, oxygen consumption during the night time (a short photoperiod) was significantly higher than that of the daytime. Q10 level was 3.50 in the light period and 3.92 in the dark period. No significant change in plasma glucose level was showned in changing salinity from 30 psu to 22 psu, while it had rapidly increased at 20 psu ($13.7{\pm}4.0mg/dL$) and thereafter all hagfish were dead at 18 psu. However, osmolarity, $Na^+$, $K^+$ and $Cl^-$ levels had significantly decreased when salinity decreased. This results are expected to develop the artificial rearing techniques of natural hagfish.

  • Effects of different photoperiod regimens on the cellular and humoral immunity in broiler chickens were studied(Exp 1). Total one hundred ninety two one-day-old commercial broiler chicks(Cobb$\times$Cobb) were raised between constant lighting(CL) and intermittent lighting (1h light: 3h darkness(IL; 1l; 3D) Body weight, feed intake and feed conversion were measured for seven week. Peripheral blood and splenic lymphocyte activities were tested at 3 and 5 wk of age by performing a mitogen cellproliferation assay with a polyclonal T-cell mitogen, concanavalin A (Con A), and B-cell mitogen, lipopolysaccharide (LPS). To investigate the effect of photoperiod on the humoral immunity, chicks were immunized with sheep red blood cell(SRBC) and iinactivated Newcastle disease virus(NDV) vaccine. Total immunoglobulin G(IgG) concentration was also determined. Diurnal change of melatonin was tested in sera. In experiment 2, 0.1ml melatonin were subcutaneously injected from three to five weeks old if immunomodulation effect of lighting regimen was due to the melatonin or not. Injections of melatonin were made at 0700h and the dosage was 10ng (M2), 100ng(M3), 1$\mu\textrm{g}$(M4) per bird daily, respectively. control were quivalent injections of vehicle(M1). Lymphocyte activities were tested and humoral immunities were examined at 5 weeks of age. Blood melatonin concentration was determined at 0h, 1, h, 2h, and 3h posterior to injection at five weeks old. It was higher in CL chicks than IL chickens during the subsequent period of 3 to 5 wk of age. However, weight gain of chicks raised IL were significantly higher at 6 wk of age than CL(P<0.05). Antibody response to NDV was not affected by both photoperiod regimens and melatonin injection, whereas anti-SRMB titer and IgG concentration were enhanced. Lymphocyte activity of chickens raised under IL was sighificantly higher than those of chickens raised under CL. Melatonin injection also increased lymphocyte activity. When peripheral blood lymphocytes were used, proliferation response to LPS and Con A were significantly increased in M2 and respectively. The results of this experiments suggest that IL improved host immune response and melatonin have immunomodulatory roles.

  • The skin exposure to solar irradiation and photoreactive xenobiotics may produce abnormal skin reaction, phototoxicity. Phototoxicity is an acute light-induced response, which occurs when photoreacive chemicals are activated by solar lights and transformed into products cytotoxic against the skin cells. Multifarious symptoms of phototoxicity are identified, skin irritation, erythema, pruritis, and edema that are similar to those of the exaggerated sunburn. Diverse organic chemicals, especially drugs, are known to induce phototoxicity, which is probably from the common possession of UV-absorbing benzene or heterocyclic rings in their molecular structures. Both UVB (290~320 nm) and UVA (320~400 nm) are responsible for the manifestation of phototoxicity. Absorption of photons and absorbed energy (hv) by photoactive chemicals results in molecular changes or generates reactive oxygen species and depending on the way how endogenous molecules are affected by phototoxicants, mechanisms of phototoxcity is categorized into two modes of action: Direct when unstable species from excited state directly react with the endogenous molecules, and indirect when endogeneous molecules react with secondary photoproducts. In order to identify phototoxic potential of a chemical, various test methods have been introduced. Focus is given to animal alternative test methods, i.e., in vitro, and in chemico assays as well as in vivo. 3T3 neutral red uptake assay, erythrocyte photohemolysis test, and phototoxicity test using human 3-dimensional (3D) epidermis model are examples of in vitro assays. In chemico methods evaluate the generation of reactive oxygen species or DNA strand break activity employing plasmid for chemicals, or drugs with phototoxic potential.

  • This study investigated the effects of the working mechanisms of proteins, mordants, and dyes, as well as the mordanting order, on dye uptake by silk fabric pre-treated with proteins and dyed with freeze-dried sappan wood water extract. Soybean protein and sodium caseinate were used as the proteins. 1. When Al mordants were not used, the dyeability of the fabrics increased upon protein pre-treatment as compared to the case without treatment. 2. Dyeing with protein pre-treatment, followed by mordanting, led to the highest dye uptake, and the optimal protein concentration was 5%. 3. The K/S values slightly decreased with an increase in the dyeing temperature, and the fabric turned dark red in color when dyeing was carried out at increasing temperature. Fabrics showed the highest dye uptake at $40^{\circ}C$. 4. Regarding the effect of time, the K/S values of the fabrics with and without protein treatment showed almost no increase after the initial dyeing time of 10min; further, there was hardly any difference in the cases with and without protein pre-treatment. 5. In case of protein pre-treatment fabrics, the washing fastness was level 2. The dry cleaning fastness showed very excellent result with level 4-5. The rubbing fastness was better in dry rubbing than in wet rubbing of the fabrics. For the light fastness, all dyed fabrics showed low fastness.

  • The purpose of this study is to investigate the effect of the traditional color sentiment on the contemporary clothing color by studying the pictures of street fashion of Dalian in China, in view of the clothing color of women in their 20-30 years of age having highest purchasing power, along with traditional Chinese color. The clothing color is various in frequency depending on the items in street fashion. Due to the seasonal impact of summer, the most frequent item was one-piece dress with the Multi of various color patterns, followed by White, Black, PB, R and B category. In the top color, the White was most prevalent color due to the seasonal factor, followed by Black, Grey, Multi, R, Y, RP category. Achromatic color is more dominant with the ratio of 7:3, comparing with its counterpart, which consists of R and Y category of V, B, P, VP tone. In the bottom color, Dp tone of PB shows most high frequency, followed by Black. This results illustrate that Chinese women prefer blue jeans and to be looked as slimmer by using of the dark colors. In the accessories, colors of bags and shoes show different results. The bag colors show the high frequency of Dk tone, YR category, and the chromatic colors are little bit dominant than achromatic ones with the ratio of 5.3:4.7. On the contrary, the shoes colors show the highest frequency in Black, the achromatic colors are more dominant than chromatic ones with the ratio of 6.6:3.4. These results somewhat diverge from the international color trend. Color trend in Dalian street fashion in which the high frequency of V tone is observed through all the colors of the items followed by P, VP, Lgr tone in sequence. In the light of Chinese traditional color preference, this result denotes that the traditional color preferences of red, yellow are still affecting the contemporary color choices of clothing in Chinese women. The high incidence of PB category in the bottom and one-piece dress does not seem to have its origin form traditional Chinese color sentiment.
