Anticardiolipin antibodies(ACA) were assayed by an enzyme-linked immunosorbent assay (ELISA) in 68 patients with Behçet's disease. Twenty seven (39.7 %) patients showed levels of ACA five standard deviations above the value of the control group. The frequency of ACA isotype IgM was found to be significantly increased in these patients. However, ACA was not found to have a significant association with clinical activity, thrombosis, positive Venereal Disease Research Laboratory(VDRL) test or antinuclear antibodies (ANA).

A 62-year-old farmer was admitted to our department because of second degree chemical burns of both buttocks ten days following accidental contact with Gramoxone, a weed killer. He was treated with oral antibiotics and cold compresses and discharged after the burned area were reepithelialized. Laboratory findings were within normal limits for three weeks. Although lung fibrosis, hepatic and renal failure can be caused by repeated absorption of paraquat (Gramoxone) through injuried skin, systemic absorption through normal skin has not been reported. During the four month follow up period there were no systemic problems nor recurrence of skin lesions. We report herein a case of chemical burns induced by Gramoxone, which is probably an occupational dermatosis of farmers handling weed killers.

The neurotoxicity of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) in rodents was investigated by measuring the locomotor activity and the changes of brain biogenic amines in MPTP-treated C57BL/6 mice. The mice showed a typical curved spine posture 24 hours after MPTP treatment. Total locomotor activity was reduced and the ratios of stereotyped activity/total locomotor activity were increased 24 hours after MPTP treatment. However no significant changes were observed 7 days after MPTP treatment. MPTP-induced changes of biogenic amines were evident only in corpus striatum, not in frontal lobe, midbrain and hippocampus; the levels of dopamine, dihydroxyphenylacetic acid (DOPAC) and homovanillic acid (HVA) were reduced by 94%, 76.3% and 60.2% after 24 hours, and 81.9%, 61.3% and 26.1% after 6 days compared to control values respectively. The ratios of DOPAC/dopamine, HVA/dopamine and HVA/DOPAC were increased 24 hours and 7 day after MPTP treatment compared to control valuse in corpus striatum, but the degree of the 7 days was less than the 24 hours. The ratios of 5-HIAA/5-HT were incresed 24 hours and 7 days after MPTP treatment in corpus striatum, but there were no significant changes in the levels of 5-hydroxyindoleacetic acid (5-HIAA) and 5-hydroxtryptamine (5-HT). In conclusion, MPTP produced parkinsonism-like behavioral and biochemical changes in C57BL/ 6 mice.

Amyloidosis is a rare disease characterized by deposition and accumulation of insoluble fibrils in various organs and tissues. Variations in the precursor proteins composing each fibril account for the diverse character of amyloidosis. Amyloidosis light chain (AL) and amyloid A amyloidosis (AA) are two clinical entities representative of this diversity. We present a case of a 58-year-old woman presenting with refractory diarrhea and abdominal pain. She was ultimately diagnosed with intestinal amyloidosis diffusely involving the small and large intestines. Even though a definitive therapeutic strategy has not been established for gastrointestinal amyloidosis, this particular patient has been successfully managed with high-dose steroids and azathioprine.

OBJECTIVES: This study aimed to observe the decrease in tooth color after home and office bleaching due to consumption of juice, soda, and coffee over a period of one year. METHODS: We obtained written consent from 30 subjects, who were divided into two groups i.e., home bleaching and office bleaching groups. They were treated with opalessence® and Zoom2 whitening gel, and the color of their teeth was assessed using shade Eye-NCC over a one-year period. A self-describing questionnaire was used to determine the frequency of juice, soda, and coffee consumption. RESULTS: The changes in color were measured before and after 1 day, 1 month, 3 months, 6 months, and 12 months. Although the tooth color slightly changed after 12 months, the teeth were brighter than the original color. Consumption of juices, sodas, and coffee is thought to be associated with decrease in tooth color, although the change was not statistically significant. CONCLUSIONS: The ΔE* values showed that the tooth bleaching effect remained for 12 months. Consuming a normal amount of juice, sodas, and coffee does not significantly reduce tooth color after tooth bleaching.

The explosive development of genomics technologies including microarrays and next generation sequencing (NGS) has provided comprehensive maps of cancer genomes, including the expression of mRNAs and microRNAs, DNA copy numbers, sequence variations, and epigenetic changes. These genome-wide profiles of the genetic aberrations could reveal the candidates for diagnostic and/or prognostic biomarkers as well as mechanistic insights into tumor development and progression. Recent efforts to establish the huge cancer genome compendium and integrative omics analyses, so-called "integromics", have extended our understanding on the cancer genome, showing its daunting complexity and heterogeneity. However, the challenges of the structured integration, sharing, and interpretation of the big omics data still remain to be resolved. Here, we review several issues raised in cancer omics data analysis, including NGS, focusing particularly on the study design and analysis strategies. This might be helpful to understand the current trends and strategies of the rapidly evolving cancer genomics research.

Although bipolar disorder is highly heritable, the identification of specific genetic variations is limited because of the complex traits underlying the disorder. We performed a genome-wide association study of bipolar disorder using a subphenotype that shows hypersomnia symptom during a major depressive episode. We investigated a total of 2,191 cases, 1,434 controls, and 703,012 single nucleotide polymorphisms (SNPs) in the merged samples obtained from the Translational Genomics Institute and the Genetic Association Information Network. The gene emerging as the most significant by statistical analysis was rs1553441 (odds ratio=0.4093; p=1.20x10-5; Permuted p=6.0x10-6). However, the 5x0-8 threshold for statistical significance required in a genome-wide association study was not achieved. The functional enrichment pathway analysis showed significant enrichments in the adhesion, development-related, synaptic transmission-related, and cell recognition-related pathways. For further evaluation, each gene of the enriched pathways was reviewed and matched with genes that were suggested to be associated with psychiatric disorders by previous genetic studies. We found that the cadherin 13 and hypocretin (orexin) receptor 2 genes may be involved in the hypersomnia symptom during a major depressive episode of bipolar disorder.
