Many factors including social rejection, family problems, loss of educational opportunity, fear, prejudice and ignorance, compound the inherent paychologicaI stress of leprosy. In ligh.t of these problems this present study was undertaken to evaluate the psychologica.l status of 1cprosy patients. The subjects of the present study were 220 patients staying at home and 304 control people living in similar isolated areas to resettlemert villages. A self reprort symptom inventory,, SCL--90 symptom check list 90) was used and the group", were analysed and compand by many factors. The results of this study are follows. -countinue-

Clear cell carcinoma of ovary is a rare epithelial ovarian tumor, and increased in its incidence recently. Clear cell carcinoma of ovary was known t,o be highly malignant than other epithelial ovarian tumors. The clinical and pathologic findings of two casea af clear cell carcinoma of ovary are reported and reviewed briefly.

BACKGROUND: Heparin-induced thrombocytopenia/ thrombosis (HITT) is recognized as the most frequent and fatal symptom complexes in patients receiving heparin therapy. The antibodies of HITT are not directly bound to heparin but bound to complexes of heparin and platelet factor 4 (PF4) derived from platelet alpha-granules. That is, HITT IgG antibody-heparin-PF4 immune complexes are bound to FcgammaRII receptor of platelets, which induced thrombocytopenia. Some researches showed the antibodies reactive to platelets could be IgM or IgA as well as IgG. So in this study, the authors tried to explain the molecular basis of heparin-PF4-isoantibody complexes . METHODS: In HITT patients who had received long-term heparin therapy, we determined HITT isoantibodies and titers using heparin:PF4 ELISA. When fifteen HITT patients with high titer antibodies (more than 1 : 100) were selected, reaction patterns of isoantibodies with the platelets were examined through serotonin release test and flow cytometry. RESULTS: All patients showed one or more isotype antibodies and the most frequent isotype was IgGl (nine patients) . In the presence of optimal concentra pion of heparin and PF4, ten patients had antibodies which activated platelets, and all of them were positive in serotonin release test. Reactive plasmas had IgGl, IgG3, IgA or IgM antibodies, and each of them except one had IgGl. These platelet activations could be blocked in vitro by anti-IV.3 antibody. Non-reactive plasmas were negative In serotonin release assay nor had TgGl. The plasmas 4hat had two or more isoantibodies showed a similar pattern of the IgG antibody by flow cytometry. CONCLUSIONS: The HITT antibodies can be all kinds of antibody isotopes, but IgA and IgM may not bind to the platelets directly. It seems to be possible only after reacting with heparin-PF4-IgG complexes.

BACKGROUND: Prospective studies suggest that C-reactive protein (CRP) is a novel and indepen-dent risk factor of coronary heart disease. High-sensitivity methods for CRP (hs-CRP) measurement are needed for this purpose. In this study, we evaluated the performance of Cobas Integra 700 (Roche Diagnostics, Basel, Switzerland) and aimed to establish the distribution of serum CRP concentrations in healthy Koreans with the hs-CRP method. METHODS: The subjects of this study were 853 males (age; 45.9 +/- 9.8 years) and 546 females (age; 45.7 +/- 10.8 years) who visited the Health Promotion Center of the Asan Medical Center for routine health checks. Hs-CRP was measured with the Cobas Integra 700. The within-day precision, the between-day precision, the degree of correlation, the linearity, and the detection limit of hs-CRP were also analyzed with the Cobas Integra 700. RESULTS: The within-day coefficients of variation (CVs) were 0% and 1.3%. The between-day CVs were 4.0% and 3.0%. The percentage of relative nonlinearity was 0.78%. The correlation coefficient of the Cobas Integra 700 with the Behring Nephelometer was 0.994. The lower detection limit was 0.064 mg/L and the functional detection limit was 0.472 mg/L. The geometric mean concentration of CRP in Koreans was 0.69 mg/L. The mean CRP of the male population was 0.79 mg/L, which was higher than that of Korean females (0.54 mg/L) (P<0.0001). There was a significant trend to higher CRP values with increasing age (P<0.05). CONCLUSIONS: The linearity, the precision, the correlation, the detection limit of the Cobas Integra 700 were satisfactory. The age and sex-specific guidelines for hs-CRP would make the early intervention for coronary heart disease possible.

Mn (manganese) is known to induce Parkinsonian neurological disorder. Several lines of evidence suggest that apoptosis is involved not only in physiological cell death during normal development but also in neurodegenerative disease. The mechanism of Mn induced cell death remains poorly understood. In the present study, we evaluated the morphologic changes and apoptotic profile in basal ganglia using rat model of Mn toxicity. The rats were divided into three groups: the first group was a control; the second group was subdivided by administration dosage of Mn into group A (5, 10 mg MnC12/ kg) and group B (20, 40 mg MnC12/kg). The rats of each subgroup received a injection of Mn via tail vein every week for 4 weeks. The second group received 4 repeated injection of 10 mg MnC12/kg in the same manner and the rats were sacrificed at day 1, 3 & 7 in group I and at day 10, 21, 42, and 90 in group II after the last injection. A significant loss of neuron and gliosis were observed in the basal ganglia in the experimental groups (p<0.05), which were more pronounced in group II than in the control or group I. No significant difference in number of nerve cells or degree of gliosis was identified in the substantia nigra. Apoptotic cells were also increased in basal ganglia of experimental groups and appeared among neurons (10%), glial cells (10%), and endothelial cells (60%). Apoptotic figures were consistently noted through the entire experimental period after Mn injection in basal ganglia. In conclusion, these results demonstrate that Mn-induced cytopathic insult affects various cell types in basal ganglia and shows variable sensitivity in the different regions of brain, especially in the apoptotic cell death of the neuron. The overaccumulation of Mn in the brain might be attributed from the breakdown of blood-brain barrier due to the injury through the apoptosis.

Tuberculous spondylitis is not rare disease. Today the posterior instrumentation and posterior or posterolateral fusion concomitant with the anterior decompression and anterior interbody fusion have been used for the treatment of spinal tuberculosis. The authors experienced a case of tuberculous spondylitis complicated with descending aortic pseudoaneurysm. An aneurysm is defined as a localized dilatation of an artery that is at least one-half the size greater than is expected for that artery. Pseudoaneurysm occurring after previous operation, trauma, and infection. Erosion of the thoracic aorta with the development of an fistula in the presence of infection is an unusual and difficult problem to manage. We report a case and review related articles briefly.

This study was carried out to evaluate the aberrant expression of p53 protein using immunobistochemical method in 54 surgically resected liver cell carcinomas and to correlate it with clinical and pathological findings. Twenty five out of 54 cases(46%) showed positive reaction in the nucleus of liver cell carcinoma and negative reaction in associated 30 cases of cirrhosis, one case of adenoma and two cases of adenomatous hyperplasia. The p53 protein expression was associated with alpha-FP level(p<0.05), but not associated with HBsAg positivity. It was significantly associated with WHO classification, Edmondson-Steiner grade and nuclear grade p53(p<0.05), but not associated with tumor size, capsule formation, portal vein invasion, cirrhosis in surrounding tissue, Eggel classification, special cell type and mitosis. In conclusion, our results suggest that the aberrant expression of p53 protein can be an advisory factor, at least, for prognosis evaluation.
