Sogunjung-tang(SGJT) has been used for the treatment of general weakness, digestive organ disease and so on. This study was carried out for the purpose of knowing the inhibitory effect on the Type I hypersensitivity and Inflammatory reactions of SGJT. The reasults were obtained as follows: SGJT(0.1, 0.5, 1, 2mg/g) concentration of dependently inhibited compound48/80 induced anaphylaxis reaction in mice. SGJT(2mg/g) also inhibited permeability of evans blue into peritoneal cavity in mice. SGJT reduced IgE, CRP, WBC and Platelets on egg albumin induced hypersensitivity. but serum NO was grown. According to above results, SGJT may be beneficial in the type I hypersensitivity and Inflammatory reactions by inhibition of histamine release from mast cells.

Seungmagalgeuntang-gamibang has long been known to have anti-allergic effect. However, the mechanism of action of Seungmagalgeuntang-gamibang is not well investigated. The author analysed the effects of Seungmagalgeuntang-gamibang on the vascular permeability, delayed-type and contact hypersensitivities, and phagocytic function, the results obtained are as follows: 1. Administration of Seungmagalgeungtang-gamibang decreased the vascular permeability induced by serotonin in the mouse. 2. Administration of Seungmagalgeuntang-gamibang decreased the vascular permeability induced by histamine without statistical significant. 3. Administration of Seungmagalgeuntang-gamibang decreased the delayed-type hypersensitivity induced by sheep red blood cells. 4. Administration of Seungmagalgeungtang-gamibang decreased the contact hypersensitivity induced by dinitrochlorobenzene. 5. Seungmagalgeungtang-gamibang increased the phagocytic-activities of macrophages in vitro and in vivo. 6. Seungmagalgeungtang-gamibang enhanced the formation of reactive oxygen intermediates in vitro and in vivo. The above results demonstrate that Seungmagalgeuntang-gamibang suppresses the hypersensitivity reactions with increasing the phagocytic functions and formations of reactive oxygen intermediates from macrophages.

The activities of twenty-one flavonoids and their related compounds on the hypersensitivity reaction against various antigens were studied in vitro and in vivo. 1. Generally flavonoids inhibited significantly the homologous passive cutaneous anaphylaxis (PCA) induced by reaginic antibody as compared as anaphylaxis by compound 48/80-induced mast cell degranulation, and so more strongly active in the IgE-mediated anaphylaxis than non-IgE-mediated anaphylaxis. 2. Flavonids inhibited remarkably Arths reaction, hemolysin titer, delayed hypersensitivity, haemagglutinin titer, rosette forming cells and plague forming cells against sheep red blood cells, and so it exhibited that flavonoids inhibited type 2, 3 and 4 hypersensitivity. 3. Quercetin, kaempferol, hesperetin, disodium cromoglycate, malvin and baicalein were active dose-dependently in the all types of hypersensitivity. Fisetin, daidzein, morin, narigin, flavone, catechin, rutin, hesperidin, neophsperidin, apigenin and chrysin were significantly active in the various types of hypersensitivity, but apigenin, rutin and catechin were less active in the delayed hypersensitivity. Taxifolin was significantly active in PCA and histamine-induced anaphylaxis except other types of hypersensitivity. Rotenone and cyanin also inhibited all types of hypersensitivity, but they are toxic. 4. Based on these results from hypersensitivity, the following flavonoid structure-activity relationships became apparent. 1) Flavonoids with $C_{2-3}$ double bond in C-ring were more active than that of $C_{2-3}$ saturation. 2) Flavonoids with $C_4$ ketone group in C-ring were more active than abscence of them except catechin and malvin. 3) Flavonoids with benzene ring at positions 2 or 3 in C-ring exhibited same activities. 4) Flavonoids with opening of the C-ring does not abolish their activities. 5) The glycosylated flavonoids in position 3 or 7 was less active than their aglycone. 6) Flavonoids with the more hydroxy group in A and B-ring were more active. 7) Flavonoids with or without $C_3-OH$ did not change their activities.

Effects of squalene on cellular and non-specific immune responses and antitumor activity in mice were investigated. Cellular and non-specific immunological assay parameters adopted in the present study were delayed-type hypersensitivity reaction and resette forming cells (RFC) for cellular immunity, activities of natural killer (NK) cells and phagocyte for non-specific immunity. Squalene resulted in marked increases of cellular and non-specific immune functions and enhancement of host resistance to tumor challenge in dose-dependent manner.

Background: Repeated administration of opioid analgesics for pain treatment can produce paradoxical hyperalgesia via peripheral and/or central mechanisms. Thus, this study investigated whether spinally (centrally) administered orexin A attenuates opioid-induced hyperalgesia (OIH). Methods: [D-Ala², N-Me-Phe⁴, Gly⁵-ol]-enkephalin (DAMGO), a selective µ-opioid receptor agonist, was used to induce mechanical hypersensitivity and was administered intradermally (4 times, 1-hour intervals) on the rat hind paw dorsum. To determine whether post- or pretreatments with spinal orexin A, dynorphin A, and anti-dynorphin A were effective in OIH, the drugs were injected through an intrathecal catheter whose tip was positioned dorsally at the L3 segment of the spinal cord (5 ㎍ for all). Mechanical hypersensitivity was assessed using von Frey monofilaments. Results: Repeated intradermal injections of DAMGO resulted in mechanical hypersensitivity in rats, lasting more than 8 days. Although the first intrathecal treatment of orexin A on the 6th day after DAMGO exposure did not show any significant effect on the mechanical threshold, the second (on the 8th day) significantly attenuated the DAMGO-induced mechanical hypersensitivity, which disappeared when the type 1 orexin receptor (OX1R) was blocked. However, intrathecal administration of dynorphin or an anti-dynorphin antibody (dynorphin antagonists) had no effect on DAMGO-induced hypersensitivity. Lastly, pretreatment with orexin A, dynorphin, or anti-dynorphin did not prevent DAMGO-induced mechanical hypersensitivity. Conclusions: Spinal orexin A attenuates mechanical hyperalgesia induced by repetitive intradermal injections of DAMGO through OX1R. These data suggest that OIH can be potentially treated by activating the orexin A-OX1R pathway in the spinal dorsal horn.

Spirodela polyrhiza(L.) Schleid (Lemnaceae) have been used as a traditional drug in treating urticaria and itching. However, the exact role of Spirodela polyrhiza in allergic reaction has not been clarified yet. Type 1 hypersensitivity (immediate hypersensitivity), popularly known as allergy, is a major clinical problem in humans. It has been found that the histamine release from mast cells is an essential step in the pathological process of immediate hypersensitivity. In the present study, the effect of aqueous extract of Spirodela polyrhiza (AESP) on immediate hypersensitivity was investigated. AESP inhibited the antigen-induced passive cutaneous anaphylaxis (PCA). AESP in vitro exhibited a dose-dependent inhibition of degranulation in RPMC stimulated by compound 48/80. AESP also suppressed the morphological changes and the increase of intracellular free calcium level induced by compound 48/80. These results suggest that inhibitory effect of AESP on immediate hypersensitivity may be mediated through the decrease of intracellular free calcium levels, and AESP importantly contributes to the treatment of anaphylaxis and may be useful for other allergic disease.

Brazilin, an active principle of Caesalprenia sappan, was examined for its immunopotentiating effects in multiple low dose streptozotocin (MLD-STZ) induced type diabetic mice. Brazilin was intraperitoneally administered for 5 consecutive days to MLD-STZ induced type 1 diabetic mice. Delayed type hypersensitivity, Con A-induced proliferation of splenocytes and mixed lymphocyte reaction, which had been decreased in diabetic mice, were significantly recovered by the administration of brazilin. Brazilin increased IL-2 production without affecting suppressor cell activity. Con A-induced and IL-2-induced expression of high affinity IL-2 receptors were also enhanced by brazilin. These results indicate that brazilin augments cellular immune responses, which are suppressed in the MLD-STZ induced type I diabetic mice, by increasing IL-2 production and responsiveness of immune cells to IL-2.
