Abstract
OBJECTIVES To clarify the clinical significance of increased signal intensities on T1 weighted magnetic resonance imaging (MRI) we performed a large-scale epidemiological study on asymptomatic manganese (Mn)-exposed workers with its focus on MRI. METHODS We randomly selected 121 male workers out of a total of 750 workers including Mn-exposed, non-exposed manual, and non-exposed clerical workers in the factories. We studied environmental and biological monitoring, neurological examination, and MRI. RESULTS The proportion of workers with increased signal intensities among the exposed, the non-exposed manual workers, and the non-exposed clerical workers was 46.1%, 18.8%, and 0%, respectively. Especially, 73.5% of the welders showed increased signal intensities. In no subject, were clinical signs of manganism observed. The pallidal index correlated with blood Mn concentration. CONCLUSION Increase in signal intensities on the T1-weighted image reflect recent exposure to Mn, but not necessarily manganism. At which increase of signal intensity, the progression of manganism from Mn exposure occurs, remains to be solved.

Abstract
The Expert Committee on the Diagnosis and Classification of Diabetes Mellitus announced the new diagnostic criteria for diabetes mellitus on 23 July 1997. The most notable change in the new criteria is a reduction in the cut-off point for fasting plasma glucose to that of 7.0 mmol/L (126 mg/dL). The present criteria have evolved through many years of intensive research and discussions. We intend to trace the path that leads to this latest recommendation so as to understand the evolution of the present criteria and its implications.

Abstract
An inhibitor of cyclooxygenase (COX)-1 activity of prostaglandin H2 synthase was isolated from aerial parts of Celastrus orbiculatus Thunb. (Celastraceae), an oriental folk medicine for rheumatoid arthritis by activity-guided column chromatographic methods. The COX inhibitor was identified as (-)-epiafzelechin, a member of flavan-3-ols by the structural analysis with HR-EI-mass, 1H-NMR and 13C-NMR spectral data. The compound exhibited a dose-dependent inhibition on the COX activity with an IC50 value of 15 microM. (-)-Epiafzelechin exhibited about 3-fold weaker inhibitory potency on the enzyme activity than indomethacin as a positive control. (-)-Epiafzelechin exhibited significant anti-inflammatory activity on carrageenin-induced mouse paw edema when the compound (100 mg/kg) was orally administrated at 1 h before carrageenin treatment.

Abstract
It is difficult to distinguish manganism from idiopathic parkinsonism by clinical signs only. Case history and examination: A 48-year-old welder for over 10 years complained of masked face, right side (arm and leg) resting tremor, and bradykinesia for over one year. Magnetic resonance imaging (MRI) findings showed symmetrical high signal intensities in the globus pallidus on T1 weighted image. These intensities disappeared almost completely six months after cessation of exposure. 18F-6-fluorodopa (18F-dopa) positron emission tomography (PET) findings showed reduced 18F-dopa uptake in the left putamen, findings which appear in idiopathic parkinsonism. A PET study is necessary to distinguish manganism from idiopathic parkinsonism, especially in a working environment with elevated Mn concentrations, such as welding.

Abstract
In recent years, the gerbil has been used as an experimental animal for study osmotic regulation, because of its inherent high degree of water re-uptake in kidney. Many evidences to explain this characteristic accumulated on the kidney level, it do not, however, manifest what concerns on hypothalmo-hypophyseal level. In this study, we have focused on the difference between the colchicine treated gerbil and rat in distributions of substance P (SP), which is known to have antidiuretic property. Unlike rat, in which a few SP+ neuron is present, SP+ neurons were abundantly observed in the paraventricular nucleus (PVN) of the gerbil. Furthermore SP+ cells in PVN were manifested in dehydrated gerbils, in spite of non-colchicine treatment. Therefore, we suggest that the abundant SP+ neurons in PVN may be a clue to address the neuroendocrinal mechanism concerning the high degree of osmotic regulation in this animal.

Abstract
Bronchial carcinoid tumour with ectopic adrenocorticotrophin (ACTH) production is an uncommon cause of Cushing's syndrome. In most instances, the patient presents with clinical hyperglucocorticolism and a search for its underlying pathology leads to the discovery of an inconspicuous bronchial carcinoid tumour, if at all. Often the tumour is not immediately detectable. We report a patient who presented in the reverse order--she initially had a large asymptomatic bronchial carcinoid tumour that subsequently manifested as clinical Cushing's syndrome after remaining quiescent for four years.

Abstract
Primary aldosteronism, though an uncommon cause of hypertension, causes significant morbidity, making it important to diagnose and treat this condition. Its evaluation requires complex and time consuming investigative procedures in order to confirm the diagnosis and to differentiate between the subtypes of aldosterone producing adenoma and idiopathic hyperaldosteronism. Often, the values of renin and aldosterone are equivocal, and the diagnosis of primary aldosteronism is in doubt. In this study, we examine the use of aldosterone to renin ratios in confirming the diagnosis of primary aldosteronism when the usual criteria of suppressed renin and elevated aldosterone are not met. We have found that an aldosterone to renin ratio of 50 has a 100% specificity and 92% sensitivity for detecting primary aldosteronism. Also, an aldosterone to renin ratio of > 2000 is suggestive of an aldosterone producing adenoma.

Abstract
The changes in airway responsiveness between before and after exercise in asthma are not well defined. We investigated the effect of exercise on PC20 (bronchial sensitivity) and maximal airway narrowing (MAN) on the dose-response curve to methacholine in 56 mildly asthmatic children. High-dose methacholine inhalation tests were performed before and 7 hr after exercise challenge. Methacholine PC20 was not changed by exercise, irrespective of exercise-induced bronchoconstriction (EIB). However, the subjects with (+)EIB displayed increased MAN after exercise, whereas those with (+/-)EIB or (-)EIB did not. The results showed that EIB may be followed by increased MAN but not by the change of bronchial sensitivity.

Abstract
OBJECTIVES Increased risk of lung cancer has been associated with employment in the steel industry. This association is thought to be due in part to increased concentrations of polycyclic aromatic hydrocarbons (PAHs) in air found in this work environment. Measurement of PAH metabolites in human urine provides a means of assessing individual internal dose of PAHs. This study examined the relative contribution of occupation and smoking to urinary concentration of 1-hydroxypyrene glucuronide (1-OHPG) among a group of workers at a steel plant. METHODS Concentrations of 1-OHPG in urine from 44 workers with jobs associated with increased air concentrations of PAHs and 40 workers with jobs with low or no exposure to PAHs were measured. 20 workers in each group were not current smokers. Urinary 1-OHPG was measured by synchronous fluorescence spectroscopy after immunoaffinity chromatography specific for PAH metabolites. RESULTS Mean (SEM) urinary 1-OHPG concentration was 2.16 (0.42) pmol/ml urine among the 44 occupationally exposed workers compared with 0.38 (0.05) among the 40 workers with no or low exposure (P < 0.0001). Mean urinary 1-OHPG concentration was 1.82 (0.41) pmol/ml urine among the 44 current smokers compared with 0.75 (0.20) among the 40 non-smokers (P < 0.005). Mean 1-OHPG concentrations in non-smokers were 0.26 (n = 20), 0.70 (n = 15), and 2.84 pmol/ml urine (n = 5) for strata of exposure to PAHs (no or low, mid, and high) based on job category; the corresponding values in smokers were 0.55 (n = 20), 0.94 (n = 12), and 4.91 pmol/ml (n = 12), respectively. Multiple linear regression showed significant differences between subjects in different PAH exposure with increased concentrations of 1-OHPG in urine. Amounts of foods containing PAHs ingested by this group of workers were relatively low and did not contribute significantly to urinary 1-OHPG concentrations. CONCLUSIONS These results indicate that 1-OHPG is a common urinary metabolite in people with recent occupational exposure to PAHs and is associated with both job category and estimated stratum of PAH exposure.

Abstract
The steroidogenic potential of gonadal tissues of the protogynous grouper (Epinephelus tauvina) was examined before and after sex inversion with 17 alpha-methyltestosterone. Incubations of gonadal tissues of the fish with [3H]testosterone resulted in the biosynthesis of 5 beta-androstane-3 beta, 17 beta-diol and 5 beta-dihydrotestosterone as the only metabolites in the female phase. Although the production of these 5 beta-reduced androgens persisted in the male phase, there was a shift toward the production of 11 beta-hydroxytestosterone and 11-ketotestosterone as major metabolites.

Abstract
Specific deficits in the processing of transient visual stimuli have been identified in reading-disabled children, and it has been shown that the filtering out of some medium to high spatial frequencies and some visible wavelengths impacts on their performance in a number of visual tasks. To assess further how these light diffusing and colour filtering manipulations might mediate visual processing, this study compared the letter-naming accuracy and visual spatial location judgements of eighteen poor readers with those made by eighteen good readers of the same age. Naming and spatial discrepancy measures were recorded for briefly displayed target letters at varying eccentricities, for each child, under a normal (NI) condition and wearing blue (Be), yellow (Yw), diffusion (Dn), blue with diffusion (BeDn), and yellow with diffusion (YwDn) optical framed lenses. A preliminary analysis of the data detected larger spatial discrepancies for the poor readers, and this finding was consistent with the presence of a deficit in transient (or magnocellular) activity in these children. Both the naming accuracy data and the spatial location data showed filter-dependent differences in reading ability. The letter-naming data showed that the addition of the blue filter to the diffusion lens significantly depressed performance only for the good readers, and that the addition of the yellow filter to the diffusion lens significantly improved performance only for the poor readers. Comparison of the spatial discrepancies showed that the rate at which location accuracy declined with increasing target eccentricity was smaller for the blue and yellow lenses than for normal viewing in the case of the good readers but not in the case of the poor readers.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Although exercise is one of the most ubiquitous triggers of acute bouts of asthma, the changes in airway responsiveness before and after exercise are not well defined. Specifically, the effect of the changes in airway responsiveness induced by exercise has not been studied on subsequent allergen exposure. To test whether the reactivity to allergen is altered by preceding exercise and to define possible factors determining it, we subjected 24 children with atopic asthma to the relevant allergen challenge on two occasions: one as a control without a preceding procedure and the other 24 hours after exercise challenge. Mean postallergen maximal percent falls in forced expiratory volume in 1 second from baseline (delta FEV1) of the whole group were higher after the exercise challenge compared with those of control in both early (< 1 hour) and late (3 to 10 hours) phases. The changes of postallergen maximal delta FEV1 between the control and post-exercise allergen challenges were not related to the early bronchial response to the preceding exercise challenge. Late asthmatic responses to exercise developed in six children, and the changes in both early and late phases were significantly higher in these children, compared with those without late asthmatic responses. Furthermore, the changes were well correlated with the magnitude of the late-phase response to preceding exercise in the group as a whole. It is concluded that an increased airway responsiveness to allergen occurs 24 hours after exercise in some patients with asthma. As the changes are related to a late bronchial response to exercise, late asthmatic response to exercise, when it occurs, may be associated with increased asthmatic symptoms for as long as 24 hours after exercise.

Abstract
The hypothesis that repeated exposure to a specific allergen will further increase bronchial responsiveness to that allergen is supported by indirect evidence. However, it has not been tested as intensely in the laboratory setting, and in some cases, conflicting results are presented. In order to test the hypothesis in the atopic subjects, allergen inhalation challenge tests were performed in 29 house dust mite (Dermatophagoides pteronyssinus) sensitive subjects with allergic rhinitis. Nine subjects displayed early asthmatic responses (EARs) to the first challenge (Group I). Twenty subjects with no significant airway response were submitted to the second challenge 24 h later. Thirteen subjects showed EARs (Group II) and two of these showed late asthmatic responses (LARs) as well. In Group II, there were significant changes between the first and second challenge in post-allergen early phase FEV1 (88.1 +/- 4.2 vs 71.7 +/- 4.2% baseline, P < 0.05) and in post-allergen late phase FEV1 (93.1 +/- 3.4 vs 86.6 +/- 7.8, P < 0.05). After the second challenge, PD20 (provocative dose of methacholine required to produce a 20% fall in FEV1) decreased significantly from the baseline values. When challenged separately with twofold dose of allergen, only three and one of the Group II showed EAR and LAR respectively. PD20 did not change significantly after this challenge. These results indicated that two repeated exposure to allergen dose, which is not enough to cause significant airway responses at a time, may provoke asthmatic airway responses in the subjects with allergic rhinitis and that this effect of priming is not attributed to the cumulative dose but to the consequent effect of repeated allergen exposure.

Abstract
Vero and HepG2 cells were cultivated on macroporous gelatin microcarriers prepared by the calcium carbonate inclusion method. Cell attachment to these microcarriers was slow. For HepG2 cells the subsequent growth was poor. Modification of the microcarriers by incorporation of (diethylamino)ethyl-HCl improved HepG2 attachment and subsequent growth. Optical sectioning with confocal microscopy allowed visualization of the distribution of cells within microcarriers. In most microcarriers, cells were found to preferentially populate regions close to the external surface and some cavities in the interior. Despite the incomplete occupancy of the interior of the microcarriers, high cell concentrations were achieved.

Abstract
Lactobacillus sp., generally considered to be a harmless indigenous bacteria of the mucous membrane, occasionally causes serious infections. Lactobacillus endocarditis is a very rare disease, and no case has been reported in Korea. Gram-positive bacilli were isolated from blood cultures of a 41-year-old man with clinically suspected subacute bacterial endocarditis. The patient had a dental procedure 3 months prior to the infection. The isolate was identified as L. casei subsp. casei based on the cultural characteristics and gas liquid chromatography of metabolic products. The patient was treated with ampicillin and improved. When Lactobacillus is isolated from the blood of an endocarditis patient, the significance should be seriously considered.

Abstract
The employees at the Pohang industrial area, where Clonorchis sinensis has been known to be endemic along the Hyungsan River, were examined parasitologically for clonorchiasis and a part of the infected cases were surveyed with a questionnaire to outline the recent infection status of C. sinensis and epidemiological parameters in the area. Total of 3,180 cases were tested by intradermal inoculation of C. sinensis antigen (Green Cross Co., Korea), and 834 (26.2%) were found positive. Out of the positive cases, 598 were subjected to fecal examination for helminth ova. The examination revealed 129 (21.6%) ova positive cases of C. sinensis, and Trichuris trichiura 1.7%, Ascaris lumbricoides 0.3%, and Metagonimus yokogawai 0.2%. The questionnaire analysis showed some significant differences between the infected and non-infected (control) groups. The infected cases were less educated than the control, and they lived at the closer area to the river, and most of them lived there over 20 years. Also they preferred eating raw fresh water fish. Most of the detected cases were treated with praziquantel and found negative for the eggs in 85.3% of them 1 year after the treatment. The present data reveal markedly decreased endemicity of clonorchiasis compared with previous prevalence rates but still clonorchiasis is endemic in the Hyungsan river basin. A comprehensive measure including case detection, treatment and education for parasite control should be applied to control clonorchiasis in such endemic areas.

Abstract
We studied a series of 89 consecutive patients who presented with thyrotoxicosis at a medical unit. Clinical parameters and laboratory abnormalities were recorded. Treatment was initiated and response in terms of side-effects, clinical and laboratory remissions were monitored. The frequency of the various clinical manifestations, cardiovascular and neurological complications were documented. Laboratory data on electrolytes, haematological changes and thyroid antibodies were noted. The treatment outcome revealed a relapse of 37.7% in patients with 6 months of treatment (90% occurred within the first year). We also noted that 6.7% of patients developed skin reaction. A treatment default rate of 30% was noted.

Abstract
A 16 year-old boy sustained fracture of the floor of the right orbital fossa in a road traffic accident with resultant diplopia and right enophthalmos. Symptoms of hypocortisolism subsequently developed. About two years after the trauma, pubertal changes which had occurred at 13-14 years had completely regressed. Endocrine testings confirmed clinical anterior hypopituitarism. Post-traumatic hypopituitarism may follow injury to the hypothalamus, the pituitary stalk or the pituitary itself. The normal thyroid stimulating hormone (TSH) response to thyrotropin releasing hormone (TRH) in this patient is in favour of a hypothalamic lesion. The patient has responded to replacement hormonal therapy.

Abstract
Thirteen non-obese, non-insulin-dependent diabetic patients were given guar granulate in an average dose of 7.1 grams daily for 8 weeks. The mean fructosamine fell from 3.3 +/- 0.69 mmol/L (p less than 0.01). Mean glycosylated haemoglobin (HbA1c) fell from 8.17 +/- 2.2% preguar to 7.67 +/- 1.81% (1 = ns) and to 7.39 +/- 1.23% (p = ns) at 8 weeks and 12 weeks postguar respectively. Eight weeks after the discontinuation of guar fructosamine rose to 3.61 +/- 0.95 mmol/L (p less than 0.05) while HbA1c rose to 8.23 +/- 2.08% (p = 0.05). There were no significant changes in fasting blood glucose, lipids, and body weight. Mild gastrointestinal side-effects occurred in 11 patients during the treatment with guar. It is concluded that daily ingestion of low dose guar modestly improves glycaemic control, such improvement dissipating by 8 weeks following cessation of its use.
