Pharmacopuncture, or herbal acupuncture, is a new form of therapy derived from combinations of two traditional therapeutic methods, herbal medicine and acupuncture therapy. To compare the efficacy between dexamethasone-pharmacopuncture (DP) and dexamethasone-oral administration (DO), the effect of DP was investigated in murine models. Anti-anaphylactic effects of dexamethasone treatments were investigated in compound 48/80-induced systemic anaphylactic reaction, ear swelling response, and passive cutaneous anaphylaxis (PCA). DP treatment significantly inhibited the compound 48/80-induced systemic anaphylactic reaction, ear swelling response, and PCA. The effects between DP and DO were on a similar level. These results indicate that DP can be used as an alternative method for DO in case of emergency.

This study was conducted to evaluate the safety of a recombinant human Factor VIII(GC-$\gamma$ AHF) manufactured by Korea Green Cross Company with different technology according to the Regulation of Korean Food and Drug Administration (l 998. 12. 3). In acute toxicity test, both genders of Sprague-Dawley rats and Beagle dogs were administered intravenously with GC-$\gamma$ AHF of three doses (3,125, 625 and 125 IU/kg), and single dose of 3,125 IU/kg, respectively. No dead animal and abnormal autopsy findings were found in Control and GC-$\gamma$ AHF treated group. Therefore, the 50% lethal dose ($LD_{50}$) of GC-$\gamma$ AHF was conidered to be higher than 3,125 IU/kg in rats and dogs. In the four weeks repeated intravenous toxicity study, GC-$\gamma$ AHF was administrated intravenosly to both genders of rats and dogs with 3 doses (500, 150, 50 IU/kg). There were neither dead animals nor significant changes of body weights during the experimental Period. In addition, no significant GC-$\gamma$ AHF related changes were found in clinical sign, urinalysis and other finding. Statistically changes were observed in hematological, biochemical and organ weight parameters of treated groups: however these changes were not dose dependent. No histopathological lesion were observed in both control and treated animals. Above data suggest that no observed adverse effect level of test materials in rats and dogs might be over 500 IU/kg/day in this study. In ocular irritation test, any injury on iris, conjunctiva and cornea in rabbits were not observed. The acute ocular irritation index (A.O.I.), mean ocular irritation index (M.O.I.) and Day-7 individual ocular irritation Index (I.O.I.) of GC-$\gamma$ AHF were 0. In the primary skin Irritation test, the primary irritation index (P.I.I.) oj GC-$\gamma$ AHF were 0. Therefore, the GC-$\gamma$ AHF is considered not to have the primary skin and eye toxicity in rabbits. In active systemic anaphylaxis (ASA) test, GC-$\gamma$ AHF and GC-$\gamma$ AHF emulsified with Freund's complete adjuvant (FCA) did not induce any symptom of anaphylactic shock in guinea pigs. In passive cutaneous anaphylxis (PCA) test, after sensitization with antisera of GC-$\gamma$ AHF sensitized mice, blue spots were observed on the hypodermis of back of rats, but diameter of each spot was smaller than 5 mm in each test groups except the positive control group. Based on the results of this study, GC-$\gamma$ AHF is not conidered to have any antigenic potential. In conclusion, at levels of up to 500 IU/kg, GC-$\gamma$ AHF did not produce treatment-related toxicity under the conditions of these acute-, four week repeated-toxicity, primary skin and eye toxicity, and antigenicity test.

The immunogenicity of the recombinant human basic fibroblast growth factor (rh-bFGF) was investigated by tests for active systemic anaphylaxis (ASA), passive cutaneous anaphylaxis (PCA), passive hemagglutination (PHA) and guinea pig maximization test (GPMT) in mice or guinea pigs. Guinea pigs were sensitized with rh-bFGF ($100-1000\;\mu\textrm{g}/kg$) or rh-bFGF-CFA mixture ($1000\;\mu\textrm{g}/kg$). All animals sensitized with rh-bFGF alone or mixture with CFA showed symptoms of anaphylactic shock. IgE antibodies to rh-bFGF were detected in sera obtained from rh-bFGF and rh-bFGF-Alum ($1000\;\mu\textrm{g}/kg$) sensitized mice, indicating that rh-bFGF has immunogenicity eliciting potential. IgG and/or IgM antibodies to rh-bFGF were also detected in all the sera obtained from sensitized mice by PHA. In the GPMT for delayed type skin reaction, no skin reaction was observed in sensitized guinea pigs after intradermal injection and dermal application of 0.01% rh- bFGF. However, these positive reactions were consistent with the results of another rh-bFGF, showing that rh- bFGF is a heterogenous protein to rodents. Considering the fact that rh-bFGF is a genuine human protein of which structure is identical to the endogenous human bFGF, it is thought that rh-bFGF is rarely associated with immunological problems in clinical use.

Basophils and mast cells are specialized effector cells in allergic reactions. Haliotis discus hannai (abalone), is valuable seafood. Abalone male viscera, which has a brownish color and has not been previously reported to show anti-allergic activities, was extracted with acetone. Six different acetone/hexane fractions (0, 10, 20, 30, 40, and 100%) were obtained using a silica column via β-hexosaminidase release inhibitory activity-guided selection in phorbol myristate acetate and a calcium ionophore, A23187 (PMACI)-induced human basophils, KU812F cells. The 40% acetone/hexane fraction (A40) exhibited the strongest inhibition of PMACI-induced-β-hexosaminidase release. This fraction dose-dependently inhibited reactive oxygen species (ROS) production and calcium mobilization without cytotoxicity. Western blot analysis revealed that A40 down-regulated PMACI-induced MAPK (ERK 1/2, p-38, and JNK) phosphorylation, and the NF-κB translocation from the cytosol to membrane. Moreover, A40 inhibited PMACI-induced interleukin (IL)-1β, IL-6, and IL-8 production. Anti-allergic activities of A40 were confirmed based on inhibitory effects on IL-4 and tumor necrosis factor alpha (TNF-α) production in compound (com) 48/80-induced rat basophilic leukemia (RBL)-2H3 cells. A40 inhibited β-hexosaminidase release and cytokine production such as IL-4 and TNF-α produced by com 48/80-stimulated RBL-2H3 cells. Furthermore, it's fraction attenuated the IgE/DNP-induced passive cutaneous anaphylaxis (PCA) reaction in the ears of BALB/c mice. Our results suggest that abalone contains the active fraction, A40 is a potent therapeutic and functional material to treat allergic diseases.

When ginsenoside Rg5, a main component isolated from red ginseng, was incubated with three human fecal microflora for 24 h, all specimens showed hydrolyzing activity: all specimens produced ginsenoside Rh3 as a main metabolite, but a minor metabolite $3{\beta},12{\beta}$-dihydroxydammar-21(22),24-diene (DD) was observed in two specimens. To evaluate the antiallergic effect of ginsenoside Rg5 and its metabolites, the inhibitory effect of ginsenoside Rg5 and its metabolite ginsenoside Rh3 against RBL-2H3 cell degranulation, mouse passive cutaneous anaphylaxis (PCA) reaction induced by the IgE-antigen complex, and mouse ear skin dermatitis induced by 12-O-tetradecanoilphorbol-13-acetate (TPA) were measured. Ginsenosides Rg5 and Rh3 potently inhibited degranulation of RBL-2H3 cells. These ginsenosides also inhibited mRNA expression of proinflammatory cytokines IL-6 and $TNF-{\alpha}$ in RBL-2H3 cells stimulated by IgE-antigen. Orally and intraperitoneally administered ginsenoside Rg3 and orally administered ginsenoside Rg5 to mice potently inhibited the PCA reaction induced by IgE-antigen complex. However, intraperitoneally administered ginsenoside Rg5 nearly did not inhibit the PCA reaction. These ginsenosides not only suppressed the swelling of mouse ears induced by TPA, but also inhibited mRNA expression of cyclooxygenase-2, $TNF-{\alpha}$, and IL-4 and activation of transcription factor NF-kB. These inhibitions of ginsenoside Rh3 were more potent than those of ginsenoside Rg5. These findings suggest that ginsenoside Rg5 may be metabolized in vivo to ginsenoside Rh3 by human intestinal microflora, and ginsenoside Rh3 may improve antiallergic diseases, such as rhinitis and dermatitis.

This study aimed to investigate the anti-allergic activity and the mechanism of action of Crassirhizomae rhizoma (CR). The extract of CR exhibited potent inhibitory activity in mast cells; its $IC_{50}$ values were $31.2{\pm}1.5{\mu}g/m{\ell}$ for rat basophile leukemia (RBL)-2H3 mast cells and $51.5{\pm}2.1{\mu}g/m{\ell}$ for bone marrow-derived mast cells by antigen stimulation. It also suppressed the expression of TNF-${\alpha}$ and IL-4 mRNAs in RBL-2H3 cells. In an in-vivo animal allergy model, it inhibited a local allergic reaction, passive cutaneous anaphylaxis (PCA), in a dose-dependent manner. With regard to the mechanism of action, CR inhibited the activating phosphorylation of Syk kinase, a key signaling protein for the activation of mast cells. Taken together, these results strongly suggested that the anti-allergic activity of CR is mediated through the inhibition of histamine release and allergic cytokine production by the inhibition of Syk in mast cells.

Antiallergic and antipsoriatic effects of korean Red Ginseng (KRG, steamed root of panax ginseng C.A. Meyer, Family Araliaceae) were measured. Orally administered KRG water extract potently inhibited passive cutaneous anaphylaxis (PCA). KRG water extract also showed the potent inhibition in oxazolone-induced mouse dermatitis, and suppressed mouse ear swelling by $39\%$ at 16 days at a dose of $0.1\%$. KRG water extract reduced the levels of mRNA of cyclooxygenase (COX)-2, $IL-1\beta$, $TNF-\alpha$ and $INF-\gamma$ increased in oxazolone-applied mouse ears, however, did not inhibit that of IL-4. KRG water extract also inhibited iNOS and COX-2 mRNA expression level of RAW264.7 cell induced by lipopolysaccharide. Based on these findings, we suggest that KRG can improve atopic and contact dermatitis by the regulation of $ IL-1\beta$ and $TNF-\alpha$ produced by macrophage cells and $interferon-\gamma$ produced by Th1 cells.
