p53 gene mutation is commonly accepted to be associated with loss of negative cell cycle control and progression of tumors. The proliferative activity of tumor cells is considered to be a valuable indicator of tumor aggressiveness. This study is intended to compare p53 protein expression with cell proliferation rates in the ovarian epithelial tumors according to the various clinicopathological parameters. Immunohistochemistry using monoclonal p53 antibody (DO-1) and PCNA antibody (PC10) was applied to 56 cases of ovarian epithelial tumors including 17 cases of borderline tumor. The results were as follows. Both immunohistochemical staining of PCNA and p53 protein showed positive reactions confined to the nuclei of tumor cells. There were significant differences of p53 protein expression rates between borderline malignancies (11.8%) and cystadenocarcinomas (56.4%) of ovary. The expression rate of p53 protein was not significantly different according to the differentiation and the stage, but the cases of strong positive reaction to p53 protein were more frequently noted in the poorly differentiated and advanced staged tumors. The PCNA indices of p53 strong positive cases were higher than those of p53 weak positive cases. In summary, p53 protein and PCNA expression may be used as an adjuvant in differentiating borderline lesions from carcinomas of ovary and predicting their biological behaviors.

Angioedma is a group of disorders with multifactorial etiology but a similar clinical expression, is characterized by swelling of subcutaneous or submucosal tissue. Systemic lupus erythematosus(SLE) is a chronic multi-systemtic disease characterized by inflammation and tissue damage resulting from deposition of auto-antibodies and immune complex. We experienced a case of angioedema which was the first manifestation of SLE in 24-year-old female patient. She had suffered from severe facial edema and multiple lymphadenopathy for six months and she also had pleural effusion, positive anti-nuclear and anti-DNA antibody test. Marked decrease of C3 and C4 levels was noted with normal antigenic level, and activity of Cl esterase inhibitor. The angioedema was not improved with anti-hitamine agents and instead disappeared with use of corticosteroid and non-steroidal anti-inflammatory drugs. Complement levels normalized after corticosteroid treament. We report a case of SLE which initial manifestation was angioedema.

BACKGROUND: There have been a few reports suggesting involvement of neutrophil as well as eosinophil in inducing bronchoconstriction aft,er inhalation of TDI. OBJECTIVE: In order to observe the source of chemokines in TDI-induced asthma, this investigation was designed to determine whether IL-8 and RANTES could be produced by human bronchial epithelial cells and whether dexamethasone had any effects on their production. Materials and METHODS: We cultured Beas-2B, a bronchial epithelial cell line, with five concentrations of TDI-human serum albumin (HSA) conjugate and compared them with those having no conjugate. The levels of IL-8 and RANTES in the supernatant were measured by ELISA. To evaluate the effect of pro-inflammatory cytokines, cells were incubated with peripheral blood mononuclear cell (PBMC) culture supernatant, which was derived from PBMC culture of a TDI -induced asthmatic subject under exposure to TDI-HSA conjugate, and then compared to those without PBMC supernatant addition. To evaluate the effect of dexamethasone, four concentrations of dexamethasone were pre-incubated and the same steps were repeated. RESULTS: There was significant production of IL-8 from bronchial epithelial cells with addition of TDI-HSA conjugate in a dose-dependent manner (p<0.05, respectively), which was significantly augmented with additions of PBMC supernatant (p<0.05, respectively) at each concentration. RANTES production was negligible, however, it increased significantly with addition of PBMC supernatant and TDI-HSA conjugate in a dose response manner(p<0.05, respectively). Compared to the untreated sample, pre-treatment of dexamethasone induced remarkable inhibitions of IL-8 and RANTES production. CONCLUSION: These results suggest that IL-8 and RANTES released from bronchial epithelial cells may contribute to neutrophil and eosinophil recruitment occurring in TDI-induced airway.

BACKGROUND AND OBJECTIVE: TDI is known to be the most prevalent cause of occupational asthma ( OA ) in Korea. However, the pathogenesis of TDI - induced occupational asthma still remains to be further clarified. So, we evaluated clinical significance of serum specific IgG and IgE antibodies to TDI - HSA conjugate in TDI - induced occupational asthma. Subjects and METHODS: Serum specific IgG and IgE antibodies to TDI - HSA conjugate were measured by enzyme linked immunosorbent assay. Serum was collected from 50 TDI- induced OA patients ( classified as group I ), and was compared with that from 13 asthmatic subjects with negative TDI - bronchoprovocation test ( BPT, group II ), allergic asthmatics ( group III ), and unexposed healthy controls ( group IV ). RESULTS: The prevalence of specific IgG was significantly higher in group I than in group II (p = 0.01) or group III (p <0.01). No significant difference was noted between group II and group III (p> 0.05). However, the prevalence of specific IgE was not different between group I and group II (p> 0.05 ) or group II and group III( p> 0.05 ). There was no significant difference in prevalence of specific IgG according to the asthmatic response during TDI bronchoprovocation test ( p> 0.05 ). No statistical significance was noted between specific IgG and IgE antibodies in group I subjects ( p> 0.05 ). CONCLUSION: These findings demonstrate that presence of specific IgG to TDI - HSA conjugate is closely related to TDI - BPT results and it may contribute to the development of TDI - induced asthma.

The Di(a+b-) phenotype is extremely rare among Caucaclans and mostly confined to mongoloids. The incidences of Di antigen among Koreans were reported to be 6.1 to 14.5%, with an average of 9.6%; it can be calculated that the frequency of Di(a+b-) is 0.25% on the average. Authors report the first case of hemolytic disease of the newborn due to anti-Dib in Korea. The Diego phenotypes of the mother, baby and father were Di(a+b-), Di(a+b+) and Di (a-b+), respectively. The mother's serum and eluate from infant's erythrocytes contained anti-DP antibody active in the antiglobulin phase. After transfusions of Di-negative red cells from the mother and mother's relative, the patient was recovered from anemia and jaundice.

BACKGROUND: The in vivo skin prick test (SPT) or in vitro detection of allergen specific IgE in serum is commonly used for the diagnosis of allergic disease. In this study, we evaluated the usefulness of a new multiple allergen simultaneous test (MAST) immunoblot assay, Polycheck Allergy (Biocheck GmbH, Germany). METHODS: A total of 100 patients with clinical findings of allergic diseases were tested by SPT and three different MAST assays: Polycheck Allergy (Biocheck GmbH, Germany), MAST CLA allergy system (Hitachi Chemical Diagnostics, USA) and Allergy Screen (R-biopharm, Germany). The results of MAST assays were compared with those of SPT. RESULTS: Concordance rates of MAST assays with SPT were 79-100% for Polycheck Allergy, 88.9-100% for MAST CLA and 72.7-98.3% for Allergy Screen. In ROC curve analysis, significant differences were observed in four of 25 allergens analysed: Alternaria, Birch, Hazelnut and D. farinae. For Alternaria and Birch, Polycheck Allergy (P<0.001) and Allergy Screen (P=0.0075) showed significantly larger AUC (area under the curve) than MAST CLA. For Hazelnut, Polycheck Allergy (P=0.0021), and for D. farinae, MAST CLA (P=0.015) showed significantly larger AUCs than the other two tests. The ROC analysis for overall 16 food allergens showed better results in Polycheck Allergy (P<0.001), and that for overall 21 inhalants did not show significant differences among three MAST assays (P>0.05). CONCLUSIONS: Since Polycheck Allergy showed similar or superior result to the others, it can be used for the detection of allergen specific IgE antibodies.

There have been a few cases of occupational allergy caused by herb materials. In this study, we report a case of occupational asthma and rhinitis sensitized by six kinds of herb materials-Ostericum (Kangwhal), Angelica (Danggui), Cnidium (Chunkung), Pinellia (Banha), Zingerber (Kunkang) and Discoreae (Sanyak) in a pharmacist working at a pharmacy. The patient had shown negative responses to 80 common inhalant and food allergens, but strong positive responses to six herb material extracts, Kangwhal, Danggui, Chunkung, Banha, Kunkang and Sanyak, were noted on skin-prick test. Bronchoprovocation test showed a dual asthmatic response to Danggui extract. Serum specific IgE antibodies to Chunkung, Banha and Sanyak were detected by enzyme-linked immunosorbent assay (ELISA) with no specific IgE binding to Kangwhal, Danggui and Kunkang extracts. In order to further characterize the allergic components of these three extracts, sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE) and electroblotting studies were performed. One IgE binding components (60 kDa) were detected within Chunkung extract, two (10, 25 kDa) in Banha and four (33, 34, 65, 98 kDa) in Sanyak. It is suggested that Chunkung, Banha and Sanyak may induce IgE-mediated bronchoconstriction in an exposed worker. Further studies are needed to investigate the pathogenic mechanisms induced by Kangwhal, Danggui and Kunkang.

Cephalosporins are well-known agents that may cause occupational asthma and there have been a few reports suggesting that the pathogenesis may be IgE-mediated. To the best of our knowledge, this is the first report of cefteram pivoxil-induced occupational asthma and detection of serum specific IgE to cefteram-HSA (human serum albumin) conjugate. A 28-year-old woman who had been occupied in a pharmaceutical company for 3 years began to experience rhinorrhea, nasal obstruction, cough, and dyspnea one year after she started work. She was involved in the filling of vials with cefteram pivoxil powder. The patient had no history of previous allergies. Skin prick test (SPT) to 80 common allergens showed negative responses and methacholine bronchoprovocation test (BPT) showed a positive response after inhalation of 0.15mg/ml. Skin prick test with cefteram pivoxil showed a strong positive response and specific BPT with cefteram demonstrated an early asthmatic response. Serum specific IgE to cefteram -HSA conjugate was detectable by ELISA. In conclusion, an IgE-mediated mechanism may be involved in the pathogenesis of cefteram pivoxil-induced bronchoconstriction in an exposed patient. Further studies will be needed to investigate if serum sIgE may be used as a useful marker to screen susceptible individuals.
