Objectives Hataedock is an orally-administered herbal extract that used to treat toxic heat and help excrete meconium accumulates in the fetus from pregnancy. This study compared the effects of Hataedock using the extract of Douchi and omega-3 to control inflammation in the colonic mucosa. Methods NC/Nga mice were divided into three groups; Control group (no treatment), FGT group (given the extract of Douchi), and O3T group (given omega-3). The 3-week-old mouse from each group were given the extract of Douchi and omega-3. After 2 weeks, the colonic mucosa tissues of the mice were observed via Immunohistochemical staining for IL-4, IL-13, CD40, $Fc{\varepsilon}RI$, $p-I{\kappa}B$, EGF in the intestinal mucosa. Results In both FGT and O3T group, IL-4, IL-13, STAT-6 levels and CD40-positive reactions were decreased. However, EGF-positive responses were increased. FGT group showed 35% decrease in IL-4, 45% decrease in IL-13, 48% decrease in CD40, 50% decrease in $Fc{\varepsilon}RI$, 54% decrease in $p-I{\kappa}B$, 52% increase in EGF compared to the control group. O3T group also showed 14% decrease in IL-4, 23% decrease in IL-13, 22% decrease in CD40, 29% decrease in $Fc{\varepsilon}RI$, 41% decrease in $p-I{\kappa}B$, 39% increase in EGF compared to the control group. Conclusions Both early administration of Douchi extract and omega-3 were effective in regulating Th2, relieving inflammation and developing colonic mucosal tissues. Hataedock with Douchi extract may be more effective in modulating immune system in colonic mucosa than omega-3.

Objectives: This study investigated the effects of Douchi Hataedock on Th2-skewed conditions to control allergic rhinitis. Methods: NC/Nga mice were divided into three groups: 10 mice were assigned to the control group (CTRL; no treatment), 10 mice to allergic rhinitis-induced (ARE) without treatment group, and 10 mice to the allergic rhinitis-induced (FGT) after Douchi Hataedock treatment group. The 3-week-old mice of the FGT group were given one 10 mg/kg dose of Douchi Hataedock extract and resensitized to allergic antigens at weeks four, five, and six. Allergic rhinitis was induced primarily in mice nasal cavities for five days after one week of final sensitization. The second induction used the same method one week after the first induction was completed. After one week, the nasal mucosal tissues of each group were observed. Immunohistochemical staining for IL-4, STAT6, CD40, $Fc{\varepsilon}RI$, substance P, MMP-9, $NF-{\kappa}B$ p65, p-IkB, and iNOS in the nasal mucosa was also performed. Results: The FGT group had less respiratory epithelial damage and less mucin secretion in goblet cells than the ARE group and showed a 62% decrease in IL-4, 85% decrease in STAT6, 71% decrease in CD40, 69% decrease in $Fc{\varepsilon}RI$, 43% decrease in substance P, 49% decrease in MMP-9, 43% decrease in NF-kB p65, 38% decrease in p-IkB, and 73% decrease in iNOS compared to the ARE group. Conclusions: Douchi Hataedock lessens inflammation in epithelial and goblet cells and reduces inflammatory mediator secretion in a mouse allergic rhinitis model.

Objectives: Hataedock is indigenous treatment of Korean medicine that administers herbal extracts orally to newborn infants for remove the fetal heat. The purpose of this study was to evaluate skin lipid barrier formation effect of Hataedock treatment with Douchi. Methods: We measured the Western blot to observe the expression of protein such as involucrin and loricrin. Moreover, we observed immunohistochemical changes in NC/Nga mice. The 3-week-old NC/Nga mice were divided into 3 groups: the 3-week-old control group (3w-Ctrl), 5-week-old control group (5w-Ctrl), and the Hataedock-treated group (5w-FGT). Only the 5w-FGT group was treated with Douchi at the 3rd week. We identified the changes of the lipid skin barrier and protein differentiation through immunohistochemical changes of involucrin, loricrin, filaggrin and acid sphingomyelinase (ASM) in the stratum corneum. Results: The expression of involucrin and loricrin was increased in the Western blot that was treated with concentration of Douchi extracts. In 5w-FGT group, loricrin-positive reaction was increased by 54.0%, involucrin-positive reaction was increased by 84.0%, filaggrin-positive reaction was increased by 108.0% and ASM-positive reaction was increased by 91.0% in the stratum corneum. Conclusions: These results suggest that Hataedock treatment with Douchi promoted skin lipid barrier formation by promoting differentiation of keratinocytes.

Objectives Hataedock method is a Korean medical therapy which removes fetal toxin by orally administering herbal decoction to neonates. This study was to observe skin damage and anti-inflammatory effect via regulating IL-4 activity in NC/Nga mice which were induced atopic dermatitis (AD)-like skin lesion by Dermatophagoides (D.) farinae after applying Douchi Hataedock method. Methods NC/Nga mice with 3 weeks of gestational age were used. Each 10 mice were allocated to the control group (Ctrl), the AD-induced group (AE), and the group which induced AD after administering Douchi extract (GT). After 4 weeks from administering Douchi extract to the mice, the primary AD was induced by applying D. farinae extract 6 times per week for 3 weeks and then the secondary AD was induced by the same method after 1 week from the primary AD induction. To identify the skin damage and anti-inflammatory effect, we observed LxR, IL-4, Fc ${\varepsilon}$ receptor, substance P, and $NF-{\kappa}B$. Results The GT group showed alleviation of skin injury and decrease in capillary angiogenesis. Stratum corneum damage, epithelial cell hyperplasia, lymphocyte infiltration, and capillary distribution relatively decreased in the GT group. LxR-positive reaction in the GT group were increased by 53% than that of the AE group. IL-4 production, $Fc{\varepsilon}$ receptor activity, and substance P-positive reaction in the GT group were decreased by 82%, 42%, and 82% respectively compare to those of the AE group. $NF-{\kappa}B$-positive reaction in the GT group were decreased by 15% compare to that of the AE group. Conclusions Hataedock method with Douchi extract alleviated AD via reducing inflammatory cytokines secreted at the early stage of AD. Thus, Douchi Hataedock method has a beneficial effect for the prevention and treatment of AD.

Objectives This study investigated the effects of Hataedock treatment with Douchi on induction of allergic rhinitis in obese induced NC/Nga mice. Methods NC/Nga mice were divided into control group (Ctrl), allergic rhinitis induced obese mice group (ARE), and allergic rhinitis induced obese mice group with Douchi Hataedock treatment (FGT). The 3-week-old mice of the FGT group were given one 10 mg/kg dose of Douchi Hataedock extract and sensitized with allergic antigens at weeks 4, 5, and 6. After 1 week of final sensitization, allergic rhinitis was induced primarily in mice nasal cavities for five days. After one week of the completion with the first induction, the second induction was introduced by the same method. After 1 week, few samples of the nasal mucosal tissues of each group were prepared. The factor of Th2 differentiation and inflammation control such that IL-4, STAT6, CD40, $Fc{\varepsilon}RI$, substance P, MMP-9, $NF-{\kappa}B$ p65, p-IkB, iNOS and COX-2 were observed by immunohistochemistry. Also, the difference in nasal mucosal injury was observed by histochemical method (PAS staining). Results The FGT group showed that reduced IL-4 production, STAT6 expression and CD40 expression by regulating excessive Th2 differentiation. Also, production of substance P and MMP-9 and activity of $Fc{\varepsilon}RI$ in mast cells were decreased. Inhibition of $NF-{\kappa}B$ p65 activity was induced by inhibition of p-IkB, and the production of inflammatory enzymes iNOS and COX-2 were decreased. In addition, the damage of intramural respiratory epithelium was low and excessive mucin secretion in goblet cells was low. Conclusions This study confirmed the possibility of controlling the allergic rhinitis in obese children who are expected to have an overactive inflammation.

Hataedock is a Korean medical treatment that administers herbal extracts orally to newborn infants. This method is used for alleviating harmful heat and excreting fetal wastes by meconium. The purpose of this study was to evaluate anti-inflammatory effect of Hataedock method with Douchi on 2,4-dinitrofluorobenzene (DNFB)-induced atopic dermatitis (AD). The 3-week-old NC/Nga mice were divided into 3 groups: the control group (Ctrl), the AD-induced group (AE), and the Hataedock-treated group (GT). Only the GT group was treated with Hataedock at the 3rd week. After 28 days from Hataedock treatment, we induced AD-like dermatitis to the AE and GT group by DNFB. The effects of Hataedock were evaluated by immunohistochemical method. In the epithelium, PKC-positive reaction of the GT group was decreased by 57%. In the dermal papillae, IL-4-positive reaction was decreased by 34%. In the dermis, the distribution of degranulated mast cells was decreased and substance P-positive reaction was decreased by 49%. In the skin tissue, edema was decreased and MMP-9-positive reaction was decreased by 71%. Tissue damage such as epithelial cell hyperplasia, infiltration of granulocyte and lymphocyte, and capillary distribution were also decreased. The Hataedock method with Douchi maintained skin barrier and inhibited skin-damaging factors via regulating Th2 differentiation. In conclusion, Hataedock has a potential for preventative treatment of AD. Further studies are necessary to investigate the immune-regulating mechanism and verify the safety and efficacy of the Hataedock method.

To evaluate the hypolipidemic effects of Cheonggukjang (CGJ), which is frequently used in Korea similar to Natto in Japan and Douchi in China like a dairy product, boiled soybeans were fermented with two Bacillus strains, B. subtilis and B. licheniforms, isolated from rice straw and their antihyperlipidemic effects of their products were investigated. Treatment with the CGJs significantly reduced blood triglyceride (TG) and total cholesterol (TC) levels and increased HDL cholesterol levels in Triton WR-1339-induced hyperlipidemic mice. The treatment of non-fermented soybeans alone also reduced blood TG and TC levels, but not significantly. Feeding the CGJs significantly lowered high blood TG and TC levels as well as body and epididymal mass weights in hyperlipidemic mice induced by the long-term feeding of a high-fat diet that increased blood HDL cholesterol levels. The B. subtilis-fermented CGJ products more potently reduced TG and TC levels, although the differences between the starters were not significant. These finding suggest that CGJ products may be effective as hypolipidemic foods by the synergistic interaction of soy and Bacillus strains.
