Morphological characters of Baemoochae, xBrassicoraphanus are mostly intermedium of the both parents, Chinese cabbage, Brassica rapa ssp. pekinensis and radish, Raphanus sativus. The upper and lower parts of the leaf resemble the shape of Chinese cabbage and radish, respectively. The midrib of the leaf is round like to that of radish, but very big more than 3 cm in diameter and white in color like that of Chinese cabbage. The root was changed from the swollen type like that of radish to the enlarged taproot like that of the land race of Chinese cabbage after attaining genetical stability. The flower is white. The seed pod is divided into 2 different parts; the upper part is radish and about 4 cm in length and holds 3-4 seeds and the lower part is Chinese cabbage and about 3 cm in length and holds 7-8 seeds. The color of seed is brown, weight per 1.000 seeds is 5.5 g and the number of seeds per mL is 120. The matured plant in the fall season is around 5 kg in weight and outer leaves are very vigorous and stiffly and inner leaves are erect and form a loose head. The leaf and the root contain a high level of sulforaphene which is well known as a functional substance for anti-cancer and anti-super-bacteria. Baemoochae is an amphidiploid and does not have the self incompatibility function. It has a high level of cross compatibility with Chinese cabbage as the female parent, but not the male parent. It is cross incompatible to cabbage, B. oleracea, black mustard, B. nigra and radish. However it is highly compatible to oil seed rape, B. napus, yellow mustard, B. carinata and partial compatible to muatard, B. juncea in the reciprocal cross.

The effective components of Schisandra chinensis are lignans (schizandrins and gomisins), which have various physiological functionalities such as anti-cancer, anti-inflammatory, and antioxidant activities. This study was carried out to determine the different parts of fruits in Schisandra chinensis to elevate their usefulness. Schisandra chinensis was separated into skin (epicarp), pulp (mesocarp), and seeds, and raw Omija and hot-dried Omija (HDO) were used as control. The most abundant component was nitrogen free extract (6.88~56.70%) followed by crude lipids (1.65~19.04%). The main mineral was K (383.10~2,024.10 mg/100 g), except in seeds where P was the main mineral. The main lignan in all parts of fruit was schizandrin, and the highest content of schizandrin was 9.46 mg/g in dried seeds. Total lignan content was 25.97 mg/g and 14.97 mg/g in dried seeds and HDO, respectively. A total of 17 components of fatty acids in seeds and HDO were detected, of which linoleic acid (72.66~73.78%), oleic acid (14.78~17.39%), palmitic acid (2.88~3.54%), and capric acid (1.70~4.93%) were determined as the major components. Main lignans and fatty acids of Schisandra chinensis fruit contain mainly seeds. Therefore, it is more efficient to use seeds than pulp and extract of fruit itself to use the components of Omija.

To diagnose the typhoid fever rapidly and accurately in clinically suspected patients, the levels of IgG subclass antibody were measured by enzyme-linked immunosorbent assay(ELISA). With symptom, blood culture and agglutination test, tested persons were categorized into 6 groups as typhoid fever, FUO, paratyphi A or B, other bacterial infctions, cancers, and control. ELISA was performed on the polyvinyl chloride plates coated with killed whole cell($10^8\;cell/ml$) of S. typhi 0901W by poly-L-lysine applied as binding substance (and polyvinyl chloride as solid phase). The distribution of the level of IgG subclass antibodies in each group was analyzed and compared with other groups. The results obtained were summarized as follow: 1. The optimal dilution of the sera from patients with typhoid fever was 1:160, and those of the sheep anti-human IgG subclass and the peroxidase conjugated rabbit anti-sheep IgG were 1:4000 and 1:5000, respectively. 2. The absorbance levels of IgG subclass in the sera of typhoid fever patients were as follows; a) IgG1 value is $0.439{\pm}0.110$ b) IgG2 value is $0.416{\pm}0.165$ c) IgG3 value is $0.449{\pm}0.145$ d) IgG4 value is $0.525{\pm}0.154$ IgG subclass levels in the sera of typhoid patients were much higher than in control group and patient with paratyphi A or B as well as other infectious diseases. The sensitivity and the specificity in differential diagnosis of typhoid fever and other febrile diseases were 92% and 79% in the assay of IgG1 respectively, whereas those in the assay of IgG2 were 97% and 72%, respectively (above absorbance 0.3). 3. The absorbance levels of IgG subclass in the serial sera of typhiod fever patients tend to decrease to the level of absorbance 0.3 in 10 months from the onset of illness. 4. The order of absorbance levels of IgG subclass in the serum of each group were typhoid fever, paratyphi A or B, other infectious diseases, control and cancer. 5. For the serodiagnosis of typhoid fever against other febrile diseases, the sensitivity and the specificity in the assay of IgG2 activity were 76% and 93% in absorbance 0.4, respectively. 6. In the distribution of the level of each IgG subclass in the sera of FUO patients which were suspected of typhoid fever, the positive rate was ranged from 36% to 82%. This suggest that more than 50% of FUO patients are caused by S. typhi.

Ulmi cortex is the elm bark or root bark of Ulmus macrocarpa Hance and has been used as an ingredient of traditional medicine for anti-inflammatory, analgesic, anti-cancer and wound healing on both the East and the West. This study investigated whether the Ulmus macrocarpa Hance Water extract (UMWE) has the in vivo and in vitro immune activating effect. Animals were orally administrated for 14 days as follows: no treat group with distilled water, cyclophosphamide (CY) group with 120 mg/kg of CY, UMWE 100+CY group with 100 mg/kg of UMWE and 120 mg/kg of CY, UMWE 200+CY group with 200 mg/kg of UMWE and 120 mg/kg of CY, UMWE 100 group with 100 mg/kg of UMWE and UMWE 200 group with 200 mg/kg of UMWE. The immunosuppressive drug CY was intraperitoneally injected to induce immune suppression. Spleen indices showed small changes in CY injected groups but splenocyte indices showed greater decrease in the same groups. However, UMWE appeared to relieve CY’s immunosuppression. UMWE also delayed in vitro splenocyte death increasing its longevity. These data obtained by MTT assay and 7-amino-actinomycin D which stains preferentially dead than live cells. UMWE alone did not show cytotoxicity based on its apoptototic effect on splenocytes in vitro and in vivo. Splenic NK cell activity was maintained by UMWE under the presence of CY in vitro. The data indicated that UMWE protects splenocytes from the immunosuppressive drug CY under in vitro and in vivo conditions.

Formaldehyde (FA) is widely used in industries, and it is an indoor and outdoor pollutant. Exposure to FA may cause inflammation and respiratory oxidative stress. Studies have demonstrated that FA can cause cancer in animal models. During the regeneration process of injured starfish (Asterina pectinifera), several changes have been observed in the expression of cytokines. In particular, higher TGF-${\beta}1$ expression has been detected in arm cut starfish extract after eight days. The current study was designed to elucidate the in-vitro and the in-vivo pharmacological effects of starfish extract on FA exposure. We investigated the protective effects of intact starfish extract and arm cut starfish extract on an IMR-90 cell line and on mouse lung injury in response to FA exposure. In the presence of FA, inhalation of the arm cut starfish extract was associated with more promising cell proliferation, TNF-${\alpha}$, NF-${\kappa}B$ decrement, and $I{\kappa}-B{\alpha}$ increment. In the experimental group, the pulmonary structure of the arm cut starfish extract-treated group in the presence of FA exposure was similar to the control group, whereas the FA exposure group showed damage to the pulmonary structure. Moreover, the arm cut starfish extracts was more effective than the intact starfish extracts in terms of the expression of TNF-${\alpha}$, NF-${\kappa}B$, $I{\kappa}-B{\alpha}$, and surfactant protein A. The results obtained in this study demonstrate that arm cut starfish extracts are more effective in protecting pulmonary structure and function against FA exposure than intact starfish extracts.

Brassica spp. vegetables have been known to have biological activities such as anti-cancer and anti-inflammatory activities. In this study, we investigated the in vitro physicochemical characteristics and antioxidant activities of commonly used Brassica spp. sprout vegetables such as kohlabi (Brassica oleracea var. gongyloides), red radish (Raphanussativus L. var. sativus), broccoli (B. oleracea var. italica), cabbage (B. rapavar. glabra Regel), rape (B. napus), radish (R. sativus), and tatsoi (B. campestris var. narinosa) sprouts. Our results showed that the vegetables with the highest total phenolics contents were the radish sprout ($24.40{\pm}1.24mg\;TAE/g$) and kohlabi sprout extracts ($23.97{\pm}0.46mg\;TAE/g$). Furthermore, the vegetable with the highest total flavonoid content was the radish sprout extract ($15.30{\pm}1.35mg\;CE/g$). However, the kohlabi sprout extract showed the highest DPPH radical scavenging value ($IC_{50}=1.95mg/mL$) and ORAC value (79.03 mM TE/g). In addition,the six kinds of Brassica spp. sprout vegetable extracts, except tatsoi, significantly inhibited the reactive oxygen species (ROS) production and showed that intracellular oxidative stress is closely related tothe accumulation of differentiated adipocytes and fat during the adipogenesis of 3T3-L1 preadipocytes. These results suggest that Brassica spp. sprout vegetables, especially kohlabi and radish sprout extracts, can be used to develop natural antioxidants.

The phytochemical compounds of Pueraria, a medicinally important leguminous plant, include various isoflavones that have weak estrogenic activity and a potential role in preventing chronic disease, cancer, osteoporosis, and postmenopausal syndrome. However, the major isoflavones are derivatives of puerarin and occur mainly as unabsorbable and biologically inactive glycosides. The bioavailability of the glucosides can be increased by hydrolysis of the sugar moiety using ${\beta}$-glucosidase. In this study, we investigated the antioxidant effects of a Pueraria extract after fermentation by Lactobacillus rhamnosus BHN-LAB 76. The L. rhamnosus BHN-LAB 76 strain was inoculated into Pueraria powder and fermented at $37^{\circ}C$ for 72 hr. The total polyphenol content of the Pueraria extract increased by about 134% and the total flavonoid content increased around 110% after fermentation with L. rhamnosus BHN-LAB 76 when compared to a non-fermented Pueraria extract. Superoxide dismutase-like activities, DPPH radical scavenging, and ABTS radical scavenging increased by approximately 213%, 190%, and 107%, respectively, in the fermented Pueraria extract compared to the non-fermented Pueraria extract. Fermentation of Pueraria extracts with L. rhamnosus BHN-LAB 76 is therefore possible and can effectively increase the antioxidant effects. These results can be applied to the development of improved foods and cosmetic materials.

Interest in edible insects such as Protaetia brevitarsis has increased rapidly, and several insect producers use these insects in industrialized mass production. However, mass rearing of insects can cause insect diseases. Sprouted barley is a valuable source of nutrients and has antioxidant, antimicrobial, anti-inflammatory, and anti-cancer effects. This study was conducted to investigate the effect of sprouted barley as a feed additive for producing healthy P. brevitarsis larvae. P. brevitarsis larvae were fed feeds with or without sprouted barley, and their body weight and larval period wewe checked weekly. To confirm the antibacterial effects of sprouted barley, in vitro bioassays were performed by counting Serratia marcescens colonies, and in vivo bioassays were performed by determining the survival rate and body weights of the S. marcescens-infected larvae. Larvae fed different feeds were analyzed for their nutrient compositions (i.e., such as proximate composition, minerals, amino acids, and heavy metals). Larvae fed 5% and 10% sprouted barley had maximum weight increases of 19.2% and 23.1%, respectively. Both treatment groups had significantly shorter larval periods than those of the control group. Sprouted barley markedly inhibited the growth of entomopathogenic S. marcescens. Furthermore, larvae fed sprouted barley exhibited higher Cu, Zn, and K levels. Seventeen amino acids were present in larvae fed sprouted barley, of which, tyrosine and glutamic acid were predominant. No heavy metals were detected in any of the investigated groups. Therefore, sprouted barley may be a suitable feed additive for producing high-quality P. brevitarsis larvae.

Hemistepta lyrata Bunge (HL) has been used as a folk remedy to treat cancer, inflammation, bleeding, hemorrhoids and fever, and leaves and young shoots have been used as famine food. Nevertheless, the biological activities and underlying mechanisms of the anti-inflammatory effects remain unclear. In this study, it was undertaken to explore the functions of the aerial part of HL as a suppressor of inflammation by using RAW 264.7 cells. As immune response parameters, the productions of as nitric oxide (NO) and prostaglandin E2 (PGE2), cytokines such tumor necrotic factor (TNF)-α and interleukin (IL)-6 were evaluated. Although the release of TNF-α remained unchanged in HL-treated RAW 264.7 cells, the productions of NO, PGE2 and IL-6 were significantly increased at concentrations with no cytotoxicity. Furthermore, HL significantly attenuated the mitogen-activated protein kinases (MAPK) pathway including decreasing the phosphorylation of the extracellular signal-regulated kinase (ERK1/2) and p38 mitogen-activated protein kinases. Collectively, this study provides evidence that HL inhibits the production of major pro-inflammatory molecules in LPS-stimulated RAW 264.7 cells via suppression of ERK and P38 MAPK signaling pathways. These findings suggest that the beneficial therapeutic effects of HL may be attributed partly to its ability to modulate immune functions in macrophages.
