We are reporting a rare case of a delayed hypersensitivity reaction caused by hyaluronidase allergy following a lumbar transforaminal epidural block. Using an intradermal skin test, we have provided evidence that the systemic allergic reaction resulted from hypersensitivity to hyaluronidase. To our knowledge, this is a rare case of a delayed hypersensitivity reaction to epidural hyaluronidase, comprised of an initial exposure to hyaluronidase with no subsequent allergic response in prior block followed by a subsequent delayed reaction to hyaluronidase during a second epidural block.

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 Allolobophora caliginosatrapezoides (Ac) polysaccharide fractions on the inflammation and hypersensitivity were studied in vivo. It showed that Ac polysaccharide fractions have the significant inhibitory activities of inflammation and hypersensitivity; They inhibited significantly the carrageenin-induced paw edema and acetic acid-induced writhing syndrome. They also inhibited significantly the Arthus reaction and delayed hypersensitivity in the sheep red blood cell-sensitized mice in accordance with the inhibition of haemaglutinin titer, haemolysin titer, plaque-forming cells and rosette-forming cells. They also improved markedly the oxazolone-induced dermatitis in rats dose-dependently. As the above results, it exhibited that Ac polysaccharide fraction inhibited not only humoral immune response, but also cell-mediated immune response. It seemed that methanol and ether extracts have also another physiological active agents.

Some of organophosphate pesticides which are the most heavily used in Korea, were examined for their effects on the murine immune system. Immunotoxicological assay parameters adaopted in this study were Arthus reaction for humoral immunity, delayed type hypersensitivity reaction for cell mediate immunity, carbon clearance for macrophage function and susceptiility to tumor challenge. Subchronic exposure of rodents to the pesticides resulted in the marked suppression of immune functions and enhancement of susceptibility to tumor challenge. Among the pesticides tested (fenitrothion, fenthion, diazinon and EPN), fenitrothion was the most suppressive in Arthus and delayed type hypersensitivity reaction.

Erythrosine used as a colouring agent in drugs, cosmetics and foods in Korea, was examined for its effects on murine immune system and methemoglobin formation. As immunotoxicologic assay parameters, we adopted circulating leukocytes and immunoorgan weights for pathotoxicology, IgM plaque forming cells and arthus reaction for humoral immunity, delayed hypersensitivity reaction of cell mediated immunity and carbon clearacnce for macrophage function. Erythrosine's effects were observed as follows; 1. Ery throsine showed no significant effects on circulating leulocyte counts and relative immunoorgan weight. 2. Erythrosine diminished IgM plaque forming cells. 3. Erythrosine decreased arthus reaction, in the dose dependent manner. 4. Erythrosine had no significant effect on delayed hypersensitivity. 5. Phagocytic and corrected phagocytic index were not affected. 6. Methemoglobin content was similar in the test and control groups.

황산화제인 Propyl gallate가 in vivo에서 정상 웅성 마우스이 세포 면역기능에 미치는 영향에 관한 실험 결과, 1. Propyl gallate는 지연형과민증을 용량의존적으로 감소시켰다. 2. Phagocitic index와 corrected phagocytic index는 Propyl gallate의 영향을 볼수 없었다. 3. Propyl gallate는 혈중 백혈구 수를 용량의존적으로 감소시켰다.

The immunological mechanism of the responses to ultraviolet (UV) B radiation in mouse models were investigated by the suppression of contact hypersensitivity (CHS) and delayed type hypersensitivity (DTH), and susceptibility to infection. However, there are some differences in immune suppression according to the different models as well as the irradiation protocols. Therefore, this review focused on the differences in the suppressive effects on CHS and DTH, and susceptibility to infection in relation to the different in vivo models. Recent advances in cytokine knockout mice experiments have the reexamination of the role of the critical cytokines in UVB-induced immune suppression, which was investigated previously by blocking antibodies. The characteristics of the suppressor cells responsible for UVB-induced tolerance were determined. The subcellular mechanism of UVB-induced immune suppression was also explained by the induction of apoptotic cells through the Fas and Fas-ligand interaction. The phagocytosis of the apoptotic cells is believed to induce the production of the immune suppressive cytokine like interleukin-10 by macrophages. Therefore, the therapeutic UVB response to a skin disease, such as psoriasis, by the depletion of infiltrating T cells could be considered in the extension line of apoptosis and immune suppression.

Two Shih-Tzu dogs with atopic dermatitis presented with delayed periocular dermatitis (PD) following the instillation of dorzolamide and dorzolamide/timolol combination eyedrops; the development of dermatologic signs took 94 and 104 d in cases 1 and 2, respectively. Hypersensitivity to anti-glaucoma eyedrops was highly suspected, and treatment was discontinued. Delayed PD was significantly relieved in cases 1 and 2, at days 155 and 64 after discontinuation, respectively. In this study, the clinical characteristics and progression of delayed PD were described to inform clinicians who may encounter this rare side effect.

5가지 식용식물인 신이(Flos magnoliae), 지실(Poncirus trifoliata), 시호(Bupleurum falcatum), 황금(Scutellaria baicalensis), 및 오미자(Schisandra chinensis)의 열수 추출물(10 mg/20 g B.W.)이 제IV형 알레르기 반응에 미치는 억제효과를 관찰하기 위하여 DNFB로 감작된 6주령의 웅성 BALB/C mouse에 1, 2차 시료를 투여한 후, 유도된 접촉성 피부염에 의한 부종도를 측정하였으며 대조 약물로는 cyclosporin(0.005 mg/20 g B.W)을 사용하였다. DNFB의 피부염증반응에 대한 귀 두께 측정은 1차 감작에서 황금, 오미자, 지실 군이 대조 군에 비하여 유의한 감소를 나타냈고(p<0.05), 약물 대조군인 cyclosporin과 같은 억제효과를 보였다. 시호, 신이 군은 대조 군에 비해 감소하는 경향을 보였으나 유의한 차이는 없었다. 억제 효과는 황금>오미자>지실>시호>신이의 순으로서 황금 군의 활성이 가장 높았다. 2차 감작에서는 오미자, 지실, 황금, 신이 군이 대조 군에 비하여 유의한 감소를 나타냈고 오미자와 지실은 약물 대조군인 cyclosporin과는 유의적인 차이는 없었지만 억제 효과가 더 컸다. 시호군은 대조 군과 유의적인 차이가 없었으며 오미자>지실>황금>신이>시호의 순으로서 오미자 군이 가장 높은 억제효과를 나타냈다.
