Objective : The aim of this study was to evaluate cross - reactivity between pollens in patients with strong skin reactivity to multiple pollens. METHODS: A pool of sera from 20 patients who showed strong skin responses( > or = 3+ ) to all three kinds of pollens ( tree, grass, and weed ) was used. Oak, ryegrass, mugwort, ragweed and hop Japanese pollens were chosen for the subject of study. The level and pattern of bound IgE to each pollen and cross - reactivity between pollens were investigated by ELISA and immunoblot experiments. RESULTS: In ELISA, the IgE of a pool of sera reacted to ryegrass and ragweed in 100%, to mugwort in 95%, to oak in 75%, and to hop Japanese in 65%, respectively. In inhibitory ELI - SA, more than 50% of bound IgE was mutually inhibited in oak vs ryegrass, oak vs mugwort, mugwort vs ryegrass and mugwort vs hop Japanese. In immunoblot, the IgE binding rate to major allergens of each pollen was 95% for hop Japanese, 75% for ragweed, 50% for ryegrass, 35% for mugwort, and 30% for oak, respectively. In inhibitory immunoblot, the mutually inhibited bound IgE could not be observed between major allergens of each pollen, but some minor allergens of oak pollen were mutually inhibited by ryegrass. CONCLUSION: Cross - reactivity between major allergens of oak, ryegrass, mugwort, ragweed and hop Japanese pollens was not observed at all, but some minor allergens of oak pollen cross-reacted with ryegrass and mugwort, and so did those of mugwort pollen with ryegrass and hop Japanese.

BACKGROUND: IL - 5 has been recognized as a potent proeosinophilic cytokine and IL-10 has been reported as an important anti - inflammatory cytokine in allergic inflammation. But the clinical roles of these cytokines in allergic asthma are still unclear. Objectives : We studied the clinical implications of IL - 5 and IL - 10 secretions from stimulated peripheral blood mononuclear cells ( PBMC ) in Dermatophagoides farinae ( DF ) atopic asthmatics ( BA ). METHODS: Thirty - six DF sensitized BA and 9 non - atopic BA were enrolled for this study. Twenty - seven out of 36 subjects were challenged by inhalation of DF crude allergen. The isolated PBMCs were cultured for 6 days with DF antigen and the stimulatory index ( SI ) and secretions of IL - 5, IFN - y and IL - 10 from PBMC were measured. We analyzed these parameters with clinical parameters. RESULTS: SI (4.2 +/- 1.0 vs. 1.3 +/- 0.3, p<0.05) and secretions of IL - 5 ( 19.9 vs. 1.7 g/L, p< 0.001 ) and IL-10 ( 185.5 vs. 34.3 g/L, p(0.05 ) from the atopic BA were significantly higher than those of non-atopic BA, but the secretion of IFN - r was not different between the two groups ( 56.6 vs. 47.3 ug/L ). No significant difference in secretions of IL - 5, IL - 10, IFN - r and SI of PBMC was found between responder and non - responder of DF inhalation challenge test. Among responders to antigen challenge test ( n = 17 ), the production of IL - 5 correlated with the productions of IL - 10 (r = 0.773, p< 0.01 ) and methacholine PC20 ( r = 0.503, p< 0.05 ). Production of IL - 5 from the PBMC of atopic mild intermittent BA ( n = 10 ) was higher than that of atopic per'sistent BA ( n = 27 ) ( p< 0.01 ), but no difference in IL - 10, IFN - r and SI was found between the two groups. Conclusions : Allergen specific productions of IL - 5 and IL - 10 from the PBMC may be specific for atopic subjects and secretion of IL - 5 from the stimulated PBMC may contribute to the pathogenesis of atopic BA. The severity of BA may be more influenced by other factors.

BACKGROUND: Although good clinical effects have been reported, immunotherapy with house dust mite ( HDM ) antigen - autologous specific antibody complex ( IC - IT ) is not yet accepted as an effective immunomodulating tool in HDM allergic diseases. We aimed to prove the clinical effect of IC - IT in HDM sensitized respiratory allergic subjects. Method : Six HDM sensitized respiratory allergic subjects were enrolled. Autologous D. farinae specific IgG was purified with DEAE ion exchange and affinity chromatography. After one year of IC - IT treatment the clinical effects were analyzed with symptom scores, methacholine PC20, ELISA assay of D. farinae specific antibodies and intradermal skin reactivity. Result : The rhinitis symptom score significantly improved after a one - year administration of IC - IT ( 1.23 +/- 0.30 vs. 0.37 +/- 0.15, p< 0.05), but no significant differences were found in asthma symptom score, intradermal skin reactivity to D. farinae and ELISA optic absorbances of D. farinae specific IgE, IgG, and IgG subclasses. Methacholine PC20 values improved in all 6 patients who were administered with IC - IT ( 0.35 vs. 1.66 mg/ml, p< 0.05 ). CONCLUSION: IC - IT may be efficient for management of HDM atopic asthma. Further studies are needed before clinical application of IC - IT in house dust mite atopic subjects.

PURPOSE: The morphologic characteristics and adhesion complex formation of cultured limbal epithelium of rabbit on amniotic membrane, in vitro and in vivo. METHODS: Rabbit limbal explants were cultured in vitro on amniotic membrane for 4 weeks. In the in vivo culture, the rabbit corneal epithelium was removed. Next, a tunnel was created at the limbus and, the edge of amniotic membrane was secured in the tunnel and cultured for 4 weeks. The proliferation of epithelium on the amniotic membrane was observed for 4 weeks at 1 week intervals. RESULTS: AE-5 immunohistochemical staining was positive and PAS staining was negative for cultured rabbit limbal epithelium, in vitro and in vivo. Hematoxylin and Eosin staining showed the morphologic characteristics of normal rabbit corneal epithelium in both groups. Transmission electron microscopy performed at an interval of 1 week showed adhesion complex by 3 weeks of in vitro culture, and no significant change was seen until week 4. The formation of the adhesion complex was shown starting at week 1 of in vivo culture and increased until week 4. CONCLUSIONS: The morphology of corneal limbal epithelium of rabbits cultured on amniotic membrane in vitro and in vivo, did not differ significantly compared with normal rabbit epithelium. In vivo culture resulted in more a normal-looking adhesion complex compared with the in vitro culture.

OBJECTIVE: To evaluate the clinical efficacy of a new air cleaning device (LG Electronics, Korea) equipped with electrostatic precipitator (EP) and photocatalytic plasma filter (PCP) in 24 respiratory allergic subjects. MATERIAL AND METHOD: Air cleaning conditioner and air cleaner were placed in living room and bedroom. Both EP and PCP (EP/PCP) filters were used for the first 4 weeks and for another 4 weeks, PCP without EP filter (PCP) was used. We measured symptom scores of asthma and rhinitis, peak expiratory flow rate (PEFR), serum eosinophil cataionic prote in? in ECP, Dermatophagoides farinae (DF) specific IgE and IgG in sera, concentrations of major allergens of DF in floor dust of living room, bedroom and in airborne dust. RESULTS: Both asthma and rhinitis symptom scores were significantly improved not only with EP/PCP filters but also with PCP filter. The morning PEFR was significantly improved with EP/PCP filters, but not with PCP filter. Frequency of salbutamol inhalation by air cleaner with EP/PCP filter tended to de crease(p=0.051), with no significant difference in serum ECP concentration. DF specific IgE significantly decreased at the 8th week with no differences in specific IgG. However, the mean Der f I levels in floor dust of bedroom (1, 128 vs. 374 ng/gm dust, p<0.01) and living room (1,516 vs 812 ng/gm dust, p<0.01) decreased, Der f1 in airborne dust measured only in 8 out of 22 subjects, and they decreased significantly with the trial of EP/PCP filter (172.2 pg/4.5m vs. 62.1 pg/4.5m, p<0.01). CONCLUSION: These results suggest that the EP/PCP air cleaner may be an effective tool for environmental control in respiratory allergic subjects.

BACKGROUND AND OBJECTIVES: The kinds of offending allergens in our environment have changed in accordance with the changes wrought in the living environment. Thus, the study of offending allergens in allergic rhinitis is important. This study attempted to find out annual and seasonal distribution of offending allergens in patients of allergic rhinitis and to investigate the common offending allergens. MATERIALS AND METHODS: A series of allergic skin tests were performed for 3,159 allergic rhinitis patients from Jan. 1981 to Jun. 1990 at the allergic clinic, St.Benedict Hospital, Pusan, Korea, and the results were reviewed. The allergic study included 1) an allergic skin test, 2) a nasal smear for eosinophil. RESULTS: The following summary shows the results of this study: 1) The ratio between male and female of allergic rhinitis patients was 1.15:1 with the peak age being the teens and the twenties (60.6%). 2) The peak season of allergic rhinitis was winter (29.6%), followed by autumn, spring and summer. 3) The common offending allergens were dust and mites (35.9%), pollens (31.2%), epithelials (24.8%). 4) The most common offending allergen was D. farinae (52.5%), followed by D. pteronyssinus, cat fur, Alder pollens and Hazel pollens. 5) 29.6% of patients reacted positive to the skin tests for perennial types of allergens only and 5.2% of patients demonstrated pure pollinosis. CONCLUSION: The most common offending allergen was found to be the dust mite, and the most common pollen was from Alder trees. Perennial types of allergic rhinitis exceeded seasonal types in their occurence.

Myelopathy is a rare but serious central nervous system complication associated with systemic lupus erythematosus (SLE). Acute transverse myelitis is the most usual involvement of SLE-related myelopathy. We reported a 17-year-old girl who developed a very extensive SLE related transverse myelitis with longitudinal involvement of the spinal cordfrom C4 to the conus medullaris. There were motor and sensory loss of both lower extremities, and bladder dysfunction over the course of 5 days. She presented T9 paraplegia ASIA A. Her neurological dysfunction was not responded to treatment with methyprednisolone and cyclophosphomide.

BACKGROUND: Peritonsillitis is a clinical condition of gross tonsillar infection in a septic patient with localized swelling in the peritonsillar region, and which encompasses both peritonsillar abscess and cellulitis. It is not rarely experienced in spite of decreasing incidence since the advent of antibiotic therapy. OBJECTIVES: Our objective was a clinical observation of many factors in relation to peritonsillitis. MATERIALS AND METHODS: A clinical observation was performed on 40 cases with peritonsillitis, who visited St. Benedict hospital during 3 years from February 1994 to March 1997. A needle aspiration was attempted at the point of maximum bulging using a 10cc syringe with an 18-gauge needle. RESULTS: Among 40 cases, 23 cases yielded pus. From those 23 cases, we could isolate 22 strains in 20 cases. Incision and drainage was performed only in cases of aspiration of pus(23 cases). There was no significant difference in duration of hospitalization between I & D group(7.17 days) and non-I & D group(6.71 days)(p>0.05). CONCLUSION: We conclude that I & D can't reduce the duration of hospitalization even though I & D is helpful for the relief of symptoms, and the adequate use of antibiotics is important for the treatment of peritonsillitis.

PURPOSE: We evaluated the technical feasibility and clinical efficacy of subintimal stent placement for long segment occlusion of the iliac artery. MATERIALS AND METHODS: From March 2003 to February 2007, subintimal stent placement for long segment occlusion of the iliac artery of 24 limbs in 22 patients was analyzed retrospectively. Endovascular access was performed via the ipsilateral femoral artery in 7 cases, via the contralateral femoral artery in 6 cases, via both femoral arteries in 10 cases and via the brachial artery in one case. The SAFARI (subintimal arterial flossing with antegrade-retrograde intervention) technique using a microcatheter was performed to recannalize iliac artery occlusion in three cases. Medical records were reviewed for the collection of follow-up data. The stent patency rate was analyzed by use of the Kaplan-Meier method. RESULTS: Subintimal stent placement was technically successful in 23 of 24 procedures (95.8%). The mean ankle-brachial index (ABI) increased from 0.26 to 0.82. The Fontaine classification was improved after stent placement in all patients. Major complications occurred in four procedures: three distal embolizations and one arterial rupture. All of the complications were successfully treated by endovascular intervention. The primary stent patency rates at 6-months, 1-, 2- and 3-years were 95%, 88%, 88% and 88%, respectively. CONCLUSION: Subintimal stent placement is a safe and effective treatment for long segment occlusion of the iliac artery.

PURPOSE: The aim of this study was to investigate whether the peroxisomal proliferator-activated receptor gamma (PPARγ) ligand troglitazone in combination with photodynamic therapy (PDT) enhances the apoptotic response of DLD-1 colon cancer cells. MATERIALS AND METHODS: The effects of troglitazone, PDT, and troglitazone in combination with PDT on cell viability and apoptosis were assessed in DLD-1 cells. Cell viability and proliferation were evaluated using the tetrazolium-based MTT assay, and apoptosis was evaluated via cell staining with propidium iodide (PI) and annexin V-FITC. The levels of pro-caspase-3 were measured via Western blot analyses. RESULTS: Treatment of troglitazone and PDT induced the growth retardation and cell death of DLD-1 cells in a dose-dependent manner, respectively. The combination treatment significantly suppressed cell growth and increased the apoptotic response of DLD-1 and resulted in apoptosis rather than necrosis, as shown by PI/annexin V staining and degradation of procaspase-3. CONCLUSION: Conclusion: These results document the anti-proliferative and apoptotic activities of PDT in combination with the PPARγ ligand troglitazone and provide a strong rationale for testing the therapeutic potential of combination treatment in colon cancer.
