Objectives : This study has been carried out to understand the effect of Cimicifugae Rhizoma and Seungmagalgeuntang on the hyperglycemic mice induced with Streptozotocin(STZ). Methods : The 60mg/kg of STZ was fed into mice twice by 24 h interval and then 120mg/kg STZ was fed again 3 days after the earlier feeding, Control group was administered mice with 0.9% saline(2mL/kg/day), and experimental groups were administered Cimicifugae Rhizoma extract(CA group, 10mg/kg/day; CB group, 30mg/kg/day) or Seungmagalgeuntang(SA group, 10mg/kg/day; SB group, 30mg/kg/day) after hyperglycemic induction for 6 weeks. Results : The body weight of experimental groups higher than control. The blood glucose concentration of the control group increased continuously reaching to 298.9 mg/dL after 6 weeks, however, significantly(p<0.01 or p<0.05) decreased in the SA and SB groups compared with control group. Blood insulin level significantly(p<0.01) increased in the experimental groups. The activities of SOD and catalase were more decreased in the experimental group than control group compared with normal group. In the point of pancreatic immunohistochemical change, the experimental group's pancreatic islets have increased and enlarged and the concentration of insulin-positive beta cells has also increased, comparing with the control group. Meanwhile forms of nucleus and mitochondria in the experimental group's hepatic cells were almost similar to the normal group. Conclusion : The result from the six weeks of observation demonstrates that the extracts from Cimicifugae Rhizoma and Seungmagalgeuntang have positive effects on lowering blood sugar level and elevating insulin concentration. The extract had also effects on recovering and regenerating pancreatic tissue of the hyperglycemic mice induced with STZ. At the same time, it had a protective effect against hepatotoxicity as well.

Allergic contact dermatitis (ACD) is a type IV delayed hypersensitivity reaction that results from exposures and subsequent sensitization to an environmental chemical. Crataegus Pinnatifida (CP) is commonly used to improve spleen function, remove retention of food, and promote blood circulation. This study is designed to investigate the effects of CP on ACD induced by 2,4-dinitrochlorobenzene (DNCB) in mice. In this experiment, the effects of CP on changes in body weights, ear and dorsum skin thicknesses, ear weights, clinical aspects on the dorsum skin, histopathological changes, spleen weights, cytokines were investigated. In addition, the effects on the proliferation rates of splenocytes were also investigated in vivo and vitro study. In results, CP spread (CPS) group and CP spread and administered (CPS+Adm) group showed decrease in spleen weights. In CPS+Adm group, dorsum skin thicknesses were decreased significantly compared to control group. CP treatment diminished erythema, desquamation and keratosis which were induced by repeated painting of DNCB. In histopathological observation, spongiosis and edema were diminished in CPS and CPS+Adm group. CP led to decrease in the proliferation rates of splenocytes in vivo and vitro. In conclusion, these data suggest that CP can decrease symptoms of ACD, so CP is useful to treat patient with ACD.

Objectives The purpose of this study was to investigate the effects of AI on AD induced by DNCB in mice. AI has antiallergic property that is useful in treating allergy-related-diseases, such as asthma, anaphylactic shock, acute bronchitis and skin diseases, skin pruritus from gastrointestinal diseases. However, AI has not been studied intensively yet regarding anti-inflammatory effect on AD. Therefore, this study was conducted on 2,4-dinitrochlorobezene (DNCB)-induced mice to investigate effects of AI in AD. Methods In the experiment, we divided mice into four groups: a normal group (NOR), a control group (CON), an AI spread group (AI spread), and an AI spread and feeding group (AI spread & feeding). Then examined the changes in the body weight, weights of spleen and ear, thickness of dorsum skin and ear skin, clinical aspects on dorsum skin, historical assessments, proliferation of splenocytes in vitro and in vivo, and cytokine (TNF-${\alpha}$, IL-10). Results From the experiment, the ear weight of AI spread & feeding group was significantly dropped and the ear thickness of both AI spread and AI spread & feeding were decreased significantly. Dorsum skin thickness was also decreased significantly in both AI spread and AI spread & feeding group. Also, AI treatment improved the symptoms of AD, such as coloration, erythema and desquamation and had a better effect on AI spread & feeding group. In histopathological observation, thickened epidermis, hyperkeratosis, pigmentation, hypergranulosis, parakeratosis were diminished as well in both AI spread and AI spread & feeding group. In vitro, we could observe when AI was increased as proliferation rate of splenocytes were increased, too. Conclusions In conclusion, these data suggest that AI can decrease symptoms of AD and show AI can be useful herbal therapy for AD.
