Authors examined 40,000 minifilms(boys and girls each 10,000 in junior and senior high schools) which were taken for survey of pulmonary tuberculosis for junior and senior high school students and checked the prevalence of scoliosis. It was considered lateral curvature of spine more than 10 degrees as nonpostural scoliosis, which were analyzed prevalence rate, degree of curvature, distribution of size of curvature, pattern of curve and direction of curvature. Following results were obtained. 1. The overall prevalence rate was 1.56; male 1.38. and female 1.70%(Junior high school 1.06%, Senior high school 2.05%). 2. Scoliosis secondary due to bony abnormality was found in 5 cases. 3. The most common pattern of curvature was the thoracic curve. 4. In sihgle curve, right to left ratio was 1.7, especially senior high school girls had more right curve and junior high school boys had more left curve. 5. The prevalence of senior high school students was greater than that of junior high school students and the degree of curvature was also severe in senior high school students than in junior high school students.

PURPOSE: Atopic dermatitis is a chronic, inflammatory relapsing skin disease fre- quently seen in children with a history of food allergy. Recently, acute allergic reaction to egg in patients with atopic dermatitis who have never been exposed to egg white protein has been reported. The pattern of antigen-antibody reaction by means of IgE and IgG western blotting was analysed to evaluate the possibility of non- dietary sensitization. METHODS: Total 16 children(<3 years old) with egg allergy were enrolled. Eight patients of them had never ingested egg before(Non-dietary sensitization, NDS) and the other 8 patients had a history of previous egg ingestion without significant clinical symptoms(Dietary sensitization, DS). Egg proteins were analysed by SOS-PAGE and antigen-antibody reaction by means of IgE and IgG was deteded by Western-Blotting. RESULTS: The pattern of IgE antibodies to egg white protein were similar in the two groups. IgG Western blotting to egg white in the two groups, the ovotran sferrine and ovalbumin were significantly bound by 100% of sera, respectively. In DS patients, specific IgG antibodies to ovomucoid was significantly bound by 87% (7/8) of sera whereas only 38%(3/8) of sera had detectable specific IgG antibodies against ovomucoid in NDS patients. CONCLUSION: Theses results suggest that specific IgE to egg white related to exposure of egg white protein regar specific IgG to ovomucoid is related to dietary ingestion of egg. Specific IgG to ovalbumin and ovotrans-ferrine show good clinical correlation, further study might be essential to clarify to this hypothesis.

PURPOSE: Recently, an increase in the number of patients sensitized to rice allergen with or without clinical symptoms has been reported. This study was designed to determine the major allergens in rice and their clinical significance. METHODS: Twenty-four children (15 boys and 9 girls; mean age, 16.3 months) with allergic disease, who were sensitized to rice antigen (by UniCAP) in the Pediatric Allergy Respiratory Center at Soonchunhyang University Hospital, were enrolled in this study. The allergenicity of various types of rice (raw, cooked, and heat-treated, simulated gastric fluid [SGF], and simulated intestinal fluid [SIF]) was investigated using sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and immunoglobulin E (IgE) immunoblots. The patients' medical records, including laboratory data and allergy symptoms after ingestion of rice were reviewed. RESULTS: Patients were sensitized to an average of 13.5 food antigens and their mean total IgE was 6,888.7 kU/L. In SDS-PAGE, more than 16 protein bands were observed in the raw rice, whereas only 14-16 kDa and 31-35 kDa protein bands were observed in cooked rice. The common SDS-PAGE protein bands observed in SGF-, SIF-, and heat-treated rice were 9, 14, and 31 kDa. In a heated-rice IgE immunoblot, protein bands of 9, 14, and 31-33 kDa were found in 27.8%, 38.9%, and 38.9% of all sera, respectively, and in 50%, 50%, and 75%, of ser a from the 4 symptomatic patients, respectively. CONCLUSION: The 9-, 14-, and 31-kDa protein bands appeared to be the major allergens responsible for rice allergy symptoms.

BACKGROUND AND OBJECTIVE: Murine system for studying allergic diseases has been popular in the fields of food allergy and development of their therapeutic strategies. However, there has been no information about the age-dependent changes of natural immune responses of naive C3H/HeJ mice. The purpose of this study was to evaluate the age-dependent changes of B and T-cell mediated immunologic parameters in naive C3H/HeJ mice, which can provide information for experimental planning and analysis of research results. SUBJECTS AND METHODS: Eight naive, female, 5-week-old C3H/HeJ mice were grown under the regular mouse chow feeding conditions for 6 weeks. Sera were obtained at week (w) 5, w6, w8 and w10 for measuring total and chow-specific IgE, IgG1 and IgG2a antibodies. Splenocyte proliferation (at w8 and w10) and cytokine production (at w6, w8 and w10) were evaluated with or without Con A stimulation with pooled splenocytes from two mice of each age group. Serum antibodies and cytokines (IL-4, IL-5, IL-12, INF-gamma, TGF-beta1) were measured by ELISA. Using RT-PCR, IL-4 and INF-gamma mRNA expressions were measured in Peyer's patch and spleen tissue at w10. RESULTS: The levels of total IgE and IgG1 were increased by age while the level of IgG2a was decreased. Chow-specific IgE and IgG2a responses were neglectable through out the whole experimental period (20-30 ng/ml or less). Chow-specific IgG1 levels were measured in the significant concentrations (200-300 ng/ml) but there was no age-dependent change through out the experiment. Con A stimulated-splenocyte proliferation indexes were variable according to the culture-durations and ages of mice. The higher proliferation indexes were observed in the wells receiving thymidine pulse at 48-hour culture, especially in the mice at w10. Con A stimulated IL-4 production in the 72-hour splenocyte culture supernatant was significantly increased at w8, and w10 while INF-gamma production increased only at w10. The changes in the production of IL-5, IL-12 and TGF-beta did not provide significant information in the present study. The ratio of IL-4/IFN-gamma mRNA expression was higher in Peyer's patch than in the spleen. CONCLUSION: The changes of B-cell and T-cell mediated immunologic parameters were complex and variable according to the age in naive C3H/HeJ mice under regular chow feeding conditions. For that reason, the information from the present study needs to be considered in the course of planning or analysing research/data using murine systems.

OBJECTIVE: Obturator neuropathy is a rare condition. Many neurosurgeons are unfamiliar with the obturator nerve anatomy. The purpose of this study was to define obturator nerve landmarks around the obturator foramen. METHODS: Fourteen cadavers were studied bilaterally to measure the distances from the nerve root to relevant anatomical landmarks near the obturator nerve, including the anterior superior iliac spine (ASIS), the pubic tubercle, the inguinal ligament, the femoral artery, and the adductor longus. RESULTS: The obturator nerve exits the obturator foramen and travels infero-medially between the adductors longus and brevis. The median distances from the obturator nerve exit zone (ONEZ) to the ASIS and pubic tubercle were 114 mm and 30 mm, respectively. The median horizontal and vertical distances between the pubic tubercle and the ONEZ were 17 mm and 27 mm, respectively. The shortest median distance from the ONEZ to the inguinal ligament was 19 mm. The median inguinal ligament lengths from the ASIS and the median pubic tubercle to the shortest point were 103 mm and 24 mm, respectively. The median obturator nerve lengths between the ONEZ and the adductor longus and femoral artery were 41 mm and 28 mm, respectively. CONCLUSION: The obturator nerve exits the foramen 17 mm and 27 mm on the horizontal and sagittal planes, respectively, from the pubic tubercle below the pectineus muscle. The shallowest area is approximately one-fifth medially from the inguinal ligament. This study will help improve the accuracy of obturator nerve surgeries to better establish therapeutic plans and decrease complications.

BACKGROUND: This study evaluated the inhibitory effects of N-acetylcysteine(NAC) and methylprednisolone on lung injury in the paraquat-poisoned rat model. METHODS: Sixty rats were divided into four groups(n=15 in each group) accordingly to the drug administered : group I, only intraperitoneally injected paraquat (20 mg/kg); group II, intraperitoneally injected paraquat and NAC(300 mg/kg); group III, intraperitoneally injected paraquat and methylprednisolone(60 mg/kg); and group IV, intraperitoneally injected paraquat, NAC(300 mg/kg), and methylprednisolone(60 mg/kg). On the 7th day after injection, the survival rate of experimental rats and the positive area of collagen fiber in the injured lung stained by Masson's trichrome were evaluated. RESULTS: 1. There were no differences in the 7-day survival rates for the four groups. 2. The percent of collagen fiber for group II(6.3+/-4.7%) was significantly decreased in comparison with that for group I (14.4+/-9.7%). 3. The percent of collagen fiber for Group III(13.2+/-5.9%) was not significantly different from that for group I(14.4+/-9.7%). 4. The percent of collagen fiber for Group IV(6.9+/-4.6%) was significantly decreased in comparison with that for group I, but was not different from that for group II. CONCLUSION: These results suggest that NAC protects against pulmonary fibrosis in paraquat-poisoned rats whereas methylprednisolone does not protect against pulmonary fibrosis.

Stroke is a rare but serious complication of acute myocardial infarction (AMI). Currently, glycoprotein (GP) IIb/IIIa inhibitor is used in clinical practice for acute coronary syndromes and percutaneous coronary interventions (PCIs). The incidence of stroke in patients receiving GP IIb/IIIa inhibitor during PCIs is very low. We report the case of a 47-year-old man who presented with AMI and suffered an acute cerebral infarction after infusion of a GP IIb/IIIa inhibitor following primary PCI.

OBJECTIVE: It is suggested that disturbance of dopaminergic system might be related to the possible mechanism of social phobia. The aim of this study was to investigate the possible association of DRD2 TaqI polymorphism and social phobia. METHOD: Fifty-one patients with social phobia and 200 comparison subjects were tested for DRD2 TaqI A polymorphism. The severity of social phobic symptoms was measured by self-report version of the Liebowitz Social Anxiety Scale(LSAS-SR) and Hamilton anxiety scale(HAM-A). RESULTS: There was no signigicant difference in the genotype, allele frequency, A1 carrier frequency, and heterozygote frequency DRD2 TaqI A polymorphism between the social phobia patients and the control groups. However, we found significant decrease in somatic anxiety of the HAM-A in the patients having A2A2 homozygotes(p=0.014). In addition, patients having A1A2 heterozygotes showed more anxiety in two subscales(p=0.042 in anxiety, p=0.019 in performance) of the LSAS-SR. CONCLUSION: These results suggest that DRD2 A2 homozygote might have a protective role against somatic anxiety, and molecular heterosis of DRD2 TaqI A polymorphism might be related with more severe anxiety in social phobia.

Background/Aims: Urinary tissue inhibitor of metalloproteinase-2 (TIMP-2) and insulin-like growth factor-binding protein 7 (IGFBP7) have been recently discovered and validated as sensitive biomarkers that can predict stage 2 or 3 acute kidney injury (AKI) development in high-risk patients. We aimed to assess whether these biomarkers could predict adverse outcomes and renal recovery in established AKI patients. Methods: This was a single-center study prospectively enrolling 124 patients diagnosed with AKI. TIMP-2, IGFBP7, neutrophil gelatinase-associated lipocalin (NGAL), and kidney injury molecule 1 (KIM-1) levels were measured at the time of diagnosis and the predictive performance of short-term outcomes and renal recovery was assessed. Results: Patients were divided into 4 quartiles according to the initial urinary TIMP-2/IGFBP7 levels. Stage 3 AKI (odds ratio [OR], 17.86), classified by the Kidney Disease Improving Global Outcomes (KDIGO), as well as the third and fourth quartiles of TIMP-2/IGFBP7 (OR, 5.75 and 44.98, respectively), were found to be independent predictors of renal replacement therapy at the time of AKI diagnosis. In addition, KDIGO stage 3 AKI (OR, 2.468) or the third of fourth quartiles of urinary TIMP-2/IGFBP7 (OR, 1.896 and 3.622, respectively) were also found to be useful in predicting nonrecovery of renal function. In a separate analysis of patients with renal recovery at discharge, initial urinary TIMP-2/IGFBP7 or urinary IGFBP7 at discharge could also predict new-onset or progressive chronic kidney disease (CKD). Conclusions In AKI patients, urine TIMP-2/IGFBP7 could serve as a biomarker for predicting adverse outcomes, renal recovery, or the development and progression of CKD.

Parsonage-Turner syndrome is a rare neurological disease of varying etiology characterized by severe shoulder pain, muscle weakness, and atrophy. Mechanisms are unclear, but are thought to be genetic and immune-mediated reactions. Rarely, Parsonage-Turner syndrome occurs as a side effect of vaccination. A 20-year-old male who worked as a soldier visited the military hospital because of shoulder pain after vaccination against typhoid and was diagnosed with Parsonage-Turner syndrome based on electromyography and joint magnetic resonance imaging. Pain was controlled with a nerve block. Intravenous immunoglobulin was administered for improvement of neurologic symptoms. This case suggests that Parsonage-Turner syndrome should be considered as a side effect of vaccination. To the best of our knowledge, this is the first report of Parsonage-Turner syndrome following vaccination in Korea.
