  • Acute autonomic neuropathy is a rare disease. Since the first case was reported by Young et.al., in 1969, a number of similar cases have been described, with some variation of the accompanied neurologic deficits. Acute autonomic and sensory neuropathy(AASN) is characterized by the acute onset of autonomic dysfunction and sensory disturbances. A 16-year-old girl experienced high fever($40^{\circ}C$) and erythematous rash on whole trunk and face followed by pain and sensory loss over the whole body, dysphagia, ataxia, urinary retention, and postural hypotension. There was no evidence of limb weakness. The electrophysiologic studies of this patient revealed sensory polyneuropathy and the various autonomic function test showed autonomic dysfunction. The recovery of her autonomic and sensory symptoms is incomplete, three months after the onset of the symptoms. The etiology of the acute autonomic and sensory neuropathy is not known. Most previous authors have suggested the dysautonomia may be an acute immunological damage to peripheral fibers of the autonomic nervous system. We report a case of acute autonomic and sensory neuropathy.

  • GM 콩으로 제조된 두부와 비지 등 콩 가공제품들의 효율적인 모니터링을 위하여 GM 콩이 0%, 1%, 3%, 5%, 100% 함유된 두부와 비지를 제조하여 이들의 삽입유전자인 5-enolpyruvylshikimate-3-phosphate synthase(epsps)를 검출하기 위한 PCR 방법과 EPSPS 발현 단백질 검출을 위한 western blotting과 lateral flow strip을 사용하여 검출 감도를 비교하였다. PCR 결과 산물의 크기가 큰 600 bp의 증폭에서 두부의 경우에는 100% GM으로 제조된 두부에서만 확인이 가능하였고, 비지에서는 5%, 100%에서 확인이 되었다. 크기가 작은 123 bp가 생성되는 실험에서는 0%를 제외한 모든 두부와 비지에서 검출되었다. Western blot 결과는 100% 두부, 비지에서만 검출이 되었고, lateral flow strip test에서는 100% 비지에서만 검출되었다. 이러한 결과로부터 GM 콩 가공식품 검출은 면역학적 방법보다는 PCR이 더 높은 민감도가 나타내는 것을 확인하였고, 또한 가공식품에서 효율적인 GMO 검출을 위해서는 100 bp 정도의 작은 크기의 PCR 산물을 이용해야 민감한 검출 결과를 보여주는 것을 확인하였다.

  • For the investigation of microbiological and immunological specificity of Bacteroides gingivalis, Bacteroides gingivalis were isolated, enumerated and characterized from 13 Korean rapidly progressive periodontitis and 7 healthy control by anaerobic culture technique. The total proportion of black-pigmented Bacteroides from Korean R.P.P. patients and healthy control were 8.78% and 0.92%, respectively, among total isolated black-pigmented Bacteroides. In antibiotic susceptibility test, Bacteroides gingivalis isolated from R.P.P. patients were sensitive to Ampicillin and Tetracycline, and resistant to Gentamicin and Erythromycin in disc diffusion method. In antibiotic broth dilution method, the minimum inhibitory concentration(MIC) to Bacteroides gingivalis was 2 unit/ml of Penicillin and $0.25{\sim}1{\mu}g/ml$ of Tetracycline, respectively. The concentration of serum IgG in rapidly progressive periodontitis patients were sigificantly higher than that of healthy control, and concentration of diluted gingival crevicular IgG has not any significant differences between two groups. Serum and gingival crevicular IgG antibody to Bacteroides gingivalis were significantly higher titer in rapidly progressive periodontitis patients to compare with healthy control. The lipopolysaccharide profiles of 2 Korean B. gingivalis in silver stained sodium dodecyl sulfate-polyacrylamide gel electrophoresis were similar to type strains of B. gingivalis and typical LPS band were appeared around the 24-Kd molecular weight. Immunodiffusion test and immunoelectrophoresis of the L.P.S. extracted from 2 Korean B. gingivalis and 2 kinds of type strains of B. gingivalis showed that B. gingivalis Korean-1 was reacted identically to B. gingivalis ATCC 33277. In trypsin and ${\alpha}$-glucosidase activity test of 2 Korean B. gingivalis, both of them revealed positive trypsin and negative ${\alpha}$-glucosidase activity, respectively. These investigation suggested that B. gingivalis is important pathogenic plaque bacteria for the pathogenesis of periodontitis and further study is needed to purify and characterize of the species-specific antigens of this organisms to develop monoclonal antibody and potential diagnostic reagents.

  • Purpose: This study aims to determine the efficacy and safety of house dust mite (HDM)-sublingual immunotherapy (SLIT) in elderly patients with AR. Methods: A total of 45 patients aged ${\geq}60years$ with HDM-induced AR who had ${\geq}3$ A/H ratio on skin prick test and/or ${\geq}0.35IU/L$ to both Dermatophagoides farinae and Dermatophagoides pteronyssinus by ImmunoCAP were enrolled in 4 university hospitals. To evaluate additional effects of HDM-SLIT, they were randomized to the SLIT-treated group (n = 30) or control group (n = 15). Rhinoconjunctivitis total symptom score (RTSS), rhinoscopy score, Korean rhinoconjunctivitis quality of life questionnaire, rhinitis control assessment test, asthma control test scores, and adverse reactions, were assessed at the first visit (V1) and after 1 year of treatment (V5); for immunological evaluation, serum levels of HDM-specific immunoglobulin A/IgE/IgG1/IgG4 antibodies and basophil response to HDMs were compared between V1 and V5 in both groups. Results: There were no significant differences in demographics, RTSS, skin reactivity to HDMs, or serum total/specific IgE levels to HDMs (P > 0.05, respectively) between the 2 groups. Nasal symptom score and RTSS decreased significantly at year 1 in the 2 groups (P < 0.05). There were no significant differences in percent decrease in nasal symptom score and RTSS at year 1 between the 2 groups (P > 0.05); however, rhinoscopic nasal symptom score decreased significantly in the SLIT-treated group (P < 0.05). Immunological studies showed that serum specific IgA levels (not specific IgE/IgG) and CD203c expression on basophils decreased significantly at V5 in the SLIT-treated group (P = 0.011 and P = 0.001, respectively), not in the control group. The control group required more medications compared to the treatment group, but there were no differences in adverse reactions. Conclusions: It is suggested that HDM-SLIT for 1 year could induce symptom improvement and may induce immunomodulation in elderly rhinitis patients.

  • Food allergies affect 7~8% of infants and young children, and their prevalence appears to have increased in recent years. Food allergy refers to an abnormal immunological reaction to a specific food. These reactions can be recurrent each time the food is ingested. Food allergy manifests itself with a wide spectrum of clinical characteristics including IgE-mediated diseases as immediate reactions, non-IgE-mediated disorders as delayed reactions, and mixed hypersensitivities. As a consequence, the clinical picture of a food allergy is pleomorphic. A well-designed oral food challenge is the most reliable diagnostic test for infants and young children whose clinical history and physical examination point towards a specific food allergy. Food specific IgE antibody tests (RAST, MAST, skin prick test, Uni-CAP, etc) are an alternative tool to determine oral food challenge for IgE-mediated disorders, but not for non-IgE-mediated allergies. Moreover, parents often impose their children on unnecessary diets without adequate medical supervision. These inappropriate dietary restrictions may cause nutritional deficiencies. This review aims to introduce clinical perspectives of food allergy in infants and young children and to orient clinicians towards different strains of diagnostic approaches, dietary management, and follow-up assessment of tolerance development.

  • The present study was undertaken to evaluate the anti-rheumatoidal arthritis effect of the R. verniciflua heartwood extract, its EtOAc fraction, and its primary flavonoids, sulfuretin and fustin. All test samples showed variably significant inhibitory effects on hind paw edema and trypsin inhibitor activity induced by Freund's complete adjuvant reagent (FCA reagent), and on vascular permeability caused by acetic acid. Treatment with 10 mg/kg (i.p.) sulfuretin for seven days inhibited edema formation by 54.2$\pm$3.0%. Test samples, especially sulfuretin, shifted the values of biochemical parameters such as serum-cholesterol, serum-triglyceride and serum-total protein toward the normal and restored the numbers of leucocytes and platelets. These results suggest that the heartwood of R. verniciflua reduces immunological injuries caused by FCA reagent provides evidence that suluretin is an active anti-rheumatoid arthritis agent.

  • The most important progress in diagnostic sciences is the increased sensitivity and specificity in diagnostic procedures due to the development of newer micromethodologies and increasing availability of immunological and molecular biological reagents. The outcome of researches in this field has already provided DNA probes and antibodies which can be used for diagnosing various kinds of diseases including inherited ones. This development can be also applied to diagnose diseases in oral and maxillofacial regions. Technological advances have yielded highly sensitive test methodologies so that low analyte concentration and small sample volume are no longer limiting factors. Therefore, saliva can be useful test fluid for an array of analytes. Salivary constituents of diagnostic significance include steroid hormones, antibodies, drugs, and tumor markers. Of the proteins present in saliva, viral-specific immunoglobulins are of the greatest diagnostic interest. The development of conjugates and antigens by recombinant DNA technique and peptide synthesis is necessary for clinical application. Several kits developed for the purpose of blood testing should be modified to permit their application to saliva. The final practical outcome of researches in diagnostic sciences will be various diagnostic agents which can be used for detection of bacteria and viruses, screening and diagnosis of diseases, genetic screening for forensic individual identification. For these purposes, collaboration researches and development between institutions and companies are essential.
