The purpose of this study was to investigate the association between inflammatory cytokines and chronic disease status in Korean elderly. The subjects were 248 elderly people aged over 65 years recruited from Health Center in Seoul. The subjects were classified into 3 groups based on their disease (diabetes, hypertension, and hyperlipidemia) status: subjects with one diagnosed disease of diabetes, hypertension, and hyperlipidemia fall into singular group (n=89), subjects with more than 2 disease into multiple group (n=39), and those with free of the diseases into normal (n=122). Anthropometric and biochemical characteristics, and dietary intakes were assessed. Dietary intakes were surveyed by 24-recall method. The means of IL-2, IL-6, MCP-1 and C3 were not differ among 3 groups. However, when subjects classified into tertiles of IL-6, MCP-1, TNF-alpha and C3 and frequencies of each tertile were compared, the multiple group showed significantly lower frequencies in lowest tertile than normal group (p < 0.05), suggesting higher tendency of inflammatory responses. For hematological values, blood pressure, triglycerides, fasting blood glucose levels were highest in multiple group (p < 0.05) compared to other 2 groups. BMI, body fat (kg), and triceps skinfold thickness were also significantly higher in multiple group than in 2 other groups (p < 0.05). Moreover, the concentrations of IL-2, IL-6 and C3 were significantly correlated with hematologic values of fasting blood glucose, total cholesterol, LDL-cholesterol, and triglycerides or obesity factors such as triceps skinfold thickness, BMI, and body fat (%). Among singular and multiple group, the subjects with higher intakes for vitamins A, C, and E showed the higher level of IL-2 and the lower level of MCP-1, and C3. In conclusion, blood concentrations of triglycerides and proinflammatory cytokines, blood pressure, obesity parameters (BMI, body fat, triceps skinfold thickness) were higher in multiple group than in normal, but this result strongly suggest that the increasement of the vitamin A, C, and E intakes would modify the cytokine levels to reduce the inflammatory response in the elderly people with chronic diseases.

Diabetic mastopathy is a rare disease that occurs in long-term insulin-dependent diabetic patient. It manifests as a hard palpable breast mass that may be clinically indistinguishable from a breast carcinoma. Mammography shows a non-specific, dense, heterogenous glandular opacity in both breasts. Sonography shows a markedly hypoechoic, ill-marginated mass with a posterior acoustic shadowing. We present the mammography, ultrasonography and MRI findings of a 54-year-old woman with diabetic mastopathy.

BACKGROUND: Defects in mitochondrial function have been shown to participate in the induction of neuronal cell injury. The extracellular-signal-regulated kinase (ERK) signaling pathway plays a crucial role in almost all cell functions, including proliferation, differentiation, survival, and death. However, the effect of ERK inhibition on oxysterol-induced apoptosis remains uncertain. METHODS: This study assessed the effect of ERK inhibition on the apoptotic effect of 7-ketocholesterol. RESULTS: Treatment with 7-ketocholesterol increased phosphorylated-ERK1/2 levels in differentiated PC12 cells, while the total amount of ERK was not altered. 7-Ketocholesterol decreased Bid and Bcl-2 levels, increased Bax and p53 levels, and promoted cytochrome c release, which elicits the activation of caspases (-8, -9, and -3), nuclear damage, and cell death. ERK and farnesyltransferase inhibitors inhibited the 7-ketocholesterol-induced phosphorylation of ERK1/2, activation of apoptosis-related proteins, and cell death in PC12 cells. CONCLUSIONS: The ERK and farnesyltransferase inhibitors, which did not exhibit toxicity, may inhibit the 7-ketocholesterol toxicity on differentiated PC12 cells by suppressing the activation of the caspase-8-dependent pathway as well as activation of the mitochondria-mediated cell-death pathway, leading to the activation of caspases. The inhibition of ERK may confer a beneficial protective effect against the neuronal cell injury induced by cholesterol oxidation products.

We present herein the occurrence of multifocal adenocarcinomas with a minute signet ring cell carcinoma that arose within a gastric inverted hyperplastic polyp (IHP) in a 40-year-old woman. Endoscopic ultrasonography demonstrated a heterogeneous hypoechoic mass in the third layer of the gastric wall. The endoscopic submucosal dissection specimen measuring 3.5x3.2x1.8 cm was a well-circumscribed protruding lesion that had a slit-shaped cavity. Histologically, the lesion consisted mainly of endophytic proliferation of hyperplastic columnar cells resembling normal foveolar epithelium. In addition, six foci of adenocarcinomas and a minute focus of signet ring cell carcinoma were randomly distributed in the superficial and deep regions. The adenocarcinoma was gradually transitioning from dysplasia, while the signet ring cell carcinoma was surrounded by hyperplastic foveolar epithelium. This is the first report of a gastric IHP with multifocal intramucosal adenocarcinomas and a signet ring cell carcinoma, and endoscopic submucosal dissection is used to completely resect it.

Lysosomal acid lipase (LAL) plays a central role in the intracellular degradation of neutral lipids derived from plasma lipoproteins. In this study, we investigated the missense mutation within exon 2 of human LAL gene changing of codon -6 of prepeptide from threonine to proline. The Thr-6Pro mutation was detected by the Hae III restriction fragment length polymorphism (RFLP) and single-strand conformation polymorphism (SSCP). We analyzed the mutation in subjects with 221 unrelated randomly selected control samples and 86 patients with familial hypercholesterolemia (FH) in Korea. We observed that mutation is present with high frequency in Korea compared to other populations studied previously. The frequency of PP homozygote in the FH group was observed considerably higher than that of control. However, there was no significant difference of genotype frequency between two groups. These results, together with the fact that plasma lipids and lipoproteins levels between genotypes showed no statistical difference, suggest that the Thr-6Pro mutation in the LAL gene may have no association with the increased risk of FH development.

BACKGROUND: The Apolipoprotein B/apolipoprotein A-I ratio (apoB/apoA-I) is a powerful clinical indicator of metabolic syndrome. However, few studies have searched for an association between ApoB/ApoA-I and metabolic syndrome in Korean patients with type 2 diabetes. We investigated the relation between ApoB/ApoA-I and the risk of metabolic syndrome and its components. METHODS: Subjects were 812 (424 males and 388 females) Korean patients who were being treated for type 2 diabetes at Huh's Diabetes Center in Seoul. The patients were classified into quartiles (lowest:Q1-highest:Q4) of ApoB/ApoA-I by gender. Anthropometric and hematological characteristics and dietary intake using a food frequency questionnaire were assessed. RESULTS: The prevalence of metabolic syndrome in our sample was 47.9% in males and 66.5% in females. The odds ratios (OR) for metabolic syndrome and for having its components were significantly increased from Q2 to Q4 quartiles of ApoB/ApoA-I in males (OR = 5.37; 95% CI = 2.98-9.65 and OR = 7.41; 95% CI = 4.04-13.6) and females (OR = 2.57; 95% CI = 1.28-5.15 and OR = 8.49; 95% CI = 4.28-16.8). These trends withstood adjustment for age, duration of type 2 diabetes, fasting blood glucose levels, and macronutrient intake both in males (OR = 5.24; 95% CI = 2.80-9.24 and OR = 7.98; 95% CI = 4.09-15.6) and in females (OR=4.41; 95% CI = 2.26-8.61 and OR = 8.29; 95% CI = 3.85-17.8). CONCLUSION: ApoB/ApoA-I appeared to be independently associated with risk of having metabolic syndrome and its components in Korean patients with type 2 diabetes after adjustment for putative risk factors including macronutrient intake, a particularly important lifestyle factor for patients with type 2 diabetes. A follow-up study of this population should evaluate the mechanisms underlying the relation between ApoB/ApoA-I and metabolic syndrome and its components.

PURPOSE: To investigate the value of the computed tomography (CT) in the study of diagnostic and post-treatment findings of pulmonary actinomycosis. MATERIALS AND METHODS: Clinical data and CT findings were retrospectively analyzed in 10 patients with histopathologically confirmed pulmonary actinomycosis. We analyzed the initial CT findings in search of patterns and distributions which suggest possible lung abnormalities and found the pleura, chest wall, and lymphadenopathy to be involved as part of the indicators of lung abnormalities. We analyzed follow-up CT findings for changes in the lungs after antibiotic therapy and recurrence after surgery. RESULTS: Of the 10 patients analyzed by CT for lung lesions, seven had been diagnosed with alcoholism and nine were male. The initial CTs (n=10) indicated that all the pulmonary lesions were solitary without chest wall involvement. However, a transfissural extension was observed in 20% of the study population (n=2). Furthermore, peripheral lung distribution and adjacent pleural thickening was observed in 70% of the study population (n=7). Within the consolidation (n=6) or mass (n=4), a central low density with peripheral enhancement was seen in 70% of the study population (n=7). A follow-up CT of the seven cases following antiobiotic therapy revealed that four cases showed minimal improvement or aggravation of their lung lesions, whereas three cases showed resolution or improvement. The improvement of the central low density was related to the improvement of consolidation or mass. Furthermore the presence of fibrosis was observed after the resolution of pulmonary lesions (n=2). No relationship was found between the duration and response of antibiotic therapy. A follow-up CT (n=4) subsequent to a lung resection revealed the onset of chest wall actinomycosis and a thickened pleura in one case. CONCLUSION: The results of this study highlight the value of the CT in pulmonary actinomycosis in order to diagnose and evaluate antibiotic responses, complications, or post-surgical recurrences of lung lesions.

Charcot-Marie-Tooth disease type 1A (CMT1A) is associated with duplication of chromosome 17p11.2-p12, whereas hereditary neuropathy with liability to pressure palsies (HNPP), which is an autosomal dominant neuropathy showing characteristics of recurrent pressure palsies, is associated with 17p11.2-p12 deletion. An altered gene dosage of PMP22 is believed to the main cause underlying the CMT1A and HNPP phenotypes. Although CMT1A and HNPP are associated with the same locus, there has been no report of these two mutations within a single family. We report a rare family harboring CMT1A duplication and HNPP deletion.

X-linked Charcot-Marie-Tooth (CMTX) disease is a clinically heterogeneous hereditary motor and sensory neuropathy. The X-linked inheritance showed an absence of male-to-male transmission and a more severe disease phenotype in affected males compared to that in affected female. A missense mutation, Cys168Arg, was found in connexin 32 gene (Cx32/GJB1) from a patient with CMTX neuropathy. The familial history of this patient also suggested that the disease is X-linked CMT. Thus, we report a CMTX family having the novel Cys168Arg mutation in the Cx32 gene.
