  • To study the antigenicity of BR92021(Vi polysaccharide typhoid vaccine), active systemic ana-phylaxis and passive cutaneous anaphylaxis were tested in guinea pigs. The groups were as follows: group I(low dose, 30 $\mu\textrm{l}$/kg), group II(high dose, 300 $\mu\textrm{l}$/kg), group III(300 $\mu\textrm{l}$/kg plus complete Freund's adjuvant), group IV(positive control, ovalbumin plus complete Freund's adjuvant) and group V(saline-treated control). Male Hartley guinea pigs at 7 weeks of age were sensitized subcutaneously with the test article or saline three times per week for three weeks(j.e., total 9 times). For groups III and IV, animals were sensitized subcutaneously with either the test article or ovalbumin plus complete Freund's adjuvant once per three week for 6 weeks(i.e., total 3 times). Twelve days after the last sensitization, the blood was collected from the sensitized animals for the passive cutaneous anaphylaxis test. In addition, the sensitized animals were subjected to the active systemic anaphylaxis test on fourteen days after the last sensitization by an intravenous challenge with either the test article or ovalbumin. In group I, mild(1/5) or moderate(4/5) symptoms of anaphylactic shock were observed. In group II, no sign(1/5), moderate(3/5) and severe(1/5) symptoms were observed. In group III, four animals of revealed moderate signs and one of 5 showed no signs of anaphylactic shock. In group IV, all 5 animals showed severe signs of shock. In group V, one of 5 revealed moderate and four of 5 showed no signs. The necropsy findings related to the active systemic anaphylaxis were observed in most animals of groups I to V In the passive cutaneous anaphylaxis test, the antiserum was diluted 10- to 5120- fold and was injected intradermally on the clipped back of recipient animals, followed by an intravenous challenge with either the test article or ovalbumin. No animals in groups I, II, III and V showed the positive reaction, whereas all animals in group IV, the positive control, showed the positive reaction at the dilution range of x1280 to x5120. Our results indicate that the test article, BR92021, may have weak antigenic potential in male guinea pigs.

  • This study was carriet out to evaluate the acute intravenous toxicity and antigenicity of Guamerin, newly developed by Mogam Biotechnology Research Institute (MBRI). In acute intravenous toxicity test, ICR mice were administered intravenously with single dose of 1,000mg/kg, and body weights and clinical signs were observed for 14 days. No dead animal, clinical signs, body weight change and abnormal autopsy findings were found in control and Gumerin treated group. Therefore, the 50% lethoal dose (LD50) of Guamerin for ICR mice was more than 1,000mg/kg on intravenous route for male and female. And the antigenic potential of Guamerin was examined by active systemic anaphylaxis(ASA) and passive cutaneous anaphylaxis(PCA) tests. In the ASA test, low and high doses (10 and 100ug/animal, respectiwely) of Guamerin were administed subcutaneously to guinea pigs for 9 times 3 weeks. All experimental groups showed negative responses whereas the positive control group given ovalbumin plus Freunds complete adjuvant (FCA) showed severe anaphylactic responses. PCA test using rats with mice anti-serum against Guamerin, low and high doses(10 and 100 ug/animal, respectively) of Guamerin were administered to mice for 9 times in 3 weeks. The anti-serum against Guamerin was administed intradermally at the back of rats, however, any positive responses were not detected in the experimental groups. These results strongly indicate that Guamerin does not induce IgE production and is not a PCA reaction inducer under these experimental conditions.

  • This study was performed to examine the antigenic potential of purified bee venom (Apis mellifera L., PBV) collected using bee venom collector. Antigenic potential of PBV was examined by active systemic anaphylaxis (ASA) in guinea pigs. PBV was subcutaneously administered at 0.025 and 0.05 mg/kg and also as a suspension with adjuvant (Freund's complete adjuvant, FCA). Ovalbumin (OVA) as a suspension with adjuvant was used to introduce positive control response. In the weight measurement and clinical observation, experimental groups didn't show any significant changes compared with control group. In the autopsy of body, the abnormalities of lung were detected only in the positive control. In the ASA test, experimental groups didn't show any symptoms of anaphylaxis like piloerection, hyperpnea and staggering gait. These results suggested that PBV didn't have antigenic potential in guinea pig.

  • Roots of Scutellaria baicalensis have been used for fever remedy; diuresis, antiphlogistic. For the investigation of the active component from aerial parts of Scutellaria baicalensis, MeOH extracts from aerial parts of Scutellaria baicalensis were suspended with $H_2O$, and partitioned by $CHCl_3$. In order to investigate the efficacy of antioxidative activity the activity guided fraction and isolation of physiologically active substance were peformed. Its $H_2O,\;30\%,\;60\%$ MeOH and MeOH fractions were examined on antioxidative activity using DPPH method and TBARS assay; It was revealed that $30\%\;and\;60\%$ MeOH fractions have significant anti-oxidative activity. its fractions testing type I allergy, compound 48/80 induced systemic anaphylaxis was applied. As a result, compared with reference (cromolygate), these fraction significantly inhibited systemic anaphylaxis by $71\%\;and\;57\%$, respectively. From $30\%,\;60\%$ MeOH fraction, five compounds were isolated and elucidated apigenin 6-C-${\alpha}$-L-arabinopyranosyl-8-C-${\beta}$-D-glucopyranoside (isoschaftside, I), scutellarein 7-O-${\beta}$-D-glucuronopyranoside (scutellarin, II), apigenin 7-O- ${\beta}$-D-glucuronopyranoside (III), isoscutellarein 8-O-${\beta}$-D-glucuronopyranoside (IV), kaempferol 3-O-${\beta}$-D-glucopyranoside (V) through their physicochemical data and spectroscopic methods. We measured radical scavenging activity with DPPH method and anti-lipid peroxidative efficacy on human LDL with TBARS assay. [$I] showed antioxidant activities in order. Type I allergy compound 48/80 induced systemic anaphylaxis was applied. $[V inhibited systemic anaphylaxis in order.

  • The immnunogenicity of the possible non-essential component of the combined vaccine (KGCC-957) for the prophylaxis against Japanese encephalitis and Hantaan virus infection recently developed by Korea Green Cross Corporation was investigated using the Hartley guinea pigs. The KGCC-95Vl was administered to the guinea pigs subcutaneously to sensitize the animals. The guinea pigs did not induce any anaphylactic immune responses which could be detectable by the active systemic anaphylaxis (ASA), the passive systemic anaphylaxis (PSA), and the passive cutaneous anaphylaxis (PCA) tests. The KGCC-95Vl is considered not to induce any anaphylactic immune responses except the prophylatic immune effects of the vaccine.

  • Objectives : We studied anti-allergic effects of Cinnamomi Ramulus(CR) herbal acupuncture and Cinnamomi Ramulus extract. Methods : In vivo, animals were herbal-acupunctured with CR at both ST36s three times for 5 days. Then, we induced active systemic anaphylatic shock using compound 48/80 in ICR mice, and passive cutaneous anaphylaxis using anti-DNP IgE in Sprague Dawley rat. In vitro, we measured cell viability, ${\beta}$ -hexosaminidase release and the expressions of IL-4, TNF-${\alpha}$ and COX-2 mRNA in RBL-2H3 cells after treatment of various concentrations of CR extract. Results : In vivo, CR herbal acupuncture pretreatments at both ST36s inhibited compound 48/80-induced active systemic anaphylatic shock. Passive cutaneous anaphylaxis was inhibited by CR herbal acupuncture pretreatments at both ST36s and optional points. In vitro, CR extract treatments did not affect on cell viability and inhibited ${\beta}$-hexosaminidase release. CR extract treatments also decreased the expressions of IL-4, TNF-${\alpha}$ and COX-2 mRNA in RBL-2H3 cells. Conclusions : These results suggest that CR herbal acupuncture and CR extract should be beneficial in the inhibition of allergic inflammatory response.

  • We investigated the effect of Saururus chinensis (Lour.) Baill (SCB) on allergy in mice. We conformed compound 48/80-induced mesenteric mast cell degranulation, active systemic anaphylatic shock and histamine release. Also observed acetic acid-induced vascular permeability and anti-dinitrophenyl (DNP) IgE-mediated passive cutaneous anaphylaxis. SCB inhibited mesenteric mast cell degranulation and active systemic anaphylatic shock induced by compound 48/80 dose-dependently. When SCB was pretreated by intra-peritoneal injection, the plasma histamine levels were reduced. SCB also significantly inhibited acetic acid-induced vascular permeability and anti-DNP IgE-mediated passive cutaneous anaphylaxis. In addition, SCB reduced IL-10 mRNA expression of the lung on ovalbumin-induced allergy. These results indicate that SCB inhibits allergy.
