After allergic contact dermatitis (ACD) elicited by application of 1 mL of 2.5% 1-chloro-2,4-dinitrochloro-benzene (DNCB) onto dorsal skin, Sprague Dawley male rats fed Scutellaria baicalensis water extract were observed to investigate the mitigative effect of Scutellaria baicalensis water extract on ACD. The Scutellaria baicalensis water extract (100 mg/kg/day) was daily administered to rats suffered from ACD. Concentrations of TBARS in plasma and liver were increased in rats with ACD. The concentrations of TBARS in liver were significantly decreased in Scutellaria baicalensis-fed group (SBFG) compared to control group (CG), but not in plasma. Liver SOD activity was significantly increased in SBFG compared to that of normal group and CG. Serum Ig E level was significantly increased in CG compared to normal group, while that of SBFG was significantly decreased. The epidermal thickness of CG was significantly increased compared to that of normal group, while that of SBFG was significantly decreased compared to that of CG. These results indicated that the Scutellaria baicalensis water extract administration was effective for antioxidative activity in liver, serum Ig E level and epidermal thickness of rats with ACD.

In order to examine the effect of Smilax china L. (SC) extract on the cytotoxicity of methymercuric chloride (MMC), allergic contact dermatitis, The cytotoxicity of MMC was assessed after cultured NIH3T3 fibroblasts were treated with various concentrations of MMC for 72 hours. And also, the following results were obtained by measuring the antioxidative effect of SC extract on the cytotoxicity of MMC. In this study, MMC remarkably decreased the cell viability of NIH3T3 fibroblasts in a dose-dependent manner, and MMC was seen to be highly-toxic below 100 uM of $XTT_{50}$ value. In addition, the toxicity of MMC was involved in oxidative stress via a blockage of MMC-induced cytotoxicity by vit. E as antioxidant. In the protective effect of SC extract on MMC-induced cytotoxicity, SC extract defended the cytotoxicity of MMC by a significant increase of cell viability which was decreased by MMC-induced cytotoxicity. It also showed antioxidative effects such as electron donating ability (EDA), superoxide dismutase (SOD)-like activity (SLA) and the lipid peroxidation activity (LPA). From these results, the natural component as SC extract may be a putative resource as the antioxidative agent for the treatment of inflammatory skin disease associated with the oxidative stress.

The effects of Acanthopanacis cortex water extract on allergic contact dermatitis (ACD) in Sprague-Dawley male rats treated with 2.5% 1-chloro-2,4-dinitrochlorobenzene (DNCB) on the dorsal skin were evaluated. The concentration of TBARS in plasma and liver was increased in ACD rats and was significantly decreased in Acanthopanacis cortex fed group (ACFG) compared to CG (control group). Serum Ig E level was significantly increased in CG compared to normal group, while that of ACFG was significantly decreased. The epidermal thickness of CG was significantly increased compared to that of normal group, while that of ACFG was significantly decreased compared to that of CG These results indicated that the Acanthopanacis cortex water extract administration improved lipid preoxidation, antioxidative activity, serum Ig E level and epidermal thickness in rats with ACD.

An expeliment was carried out to measure the cellular immune response in guinea pigs by sensitizing the animals with 2, 4-dinitrochlorobenzene(DNCB). The guinea pigs could be sensitized with one application of DNCB. The sensitizing and challenge dose was standardized. The histological response was characteristic of a delayed hypersensitivity reaction.

Objective & Methods : Experimental studies were done to research the clinical effects of Juglandis Semen aqua-acupuncture and acupuncture($BL_{13}{\cdot}BL_{17}$) on the anti-allergic response. anaphylaxis provoked by the compound48/80, delayed type hypersensitivity response to picryl chloride and SRBC and inflammation response to egg albumin. Results : The following results have been obtained; 1. Juglandis Semen aqua-acupuncture and acupuncture($BL_{13}{\cdot}BL_{17}$) group were increased the survival rate in compound 48/80 induced systemic anaphylactic reaction. 2. Picryl chloride induced contact dermatitis and delayed type hypersensitivity in SRBC challenged mouse were significantly decreased in Juglandis Semen aqua-acupuncture and acupuncture($BL_{13}{\cdot}BL_{17}$) group. 3. Inflammation response-WBC, CRP and Nitric Oxide in egg albumin induced allergic rat were significantly decreased in Juglandis Semen aqua-acupuncture and acupuncture($BL_{13}{\cdot}BL_{17}$) group. Conclusions : According to the above results, Semen aqua-acupuncture and acupuncture($BL_{13}{\cdot}BL_{17}$) both depress the allergy reaction.
