Ochratoxin A is a natural contaminant of mouldy food and feed, which is produced by Penicillium and Aspergillus, and is suspected of being one of the etiological agents responsible for Balkan endemic nephropathy and the associated urinary tract tumors. For evaluation of the mutagenicity of ochratoxin A, we performed in vitro chromosome aberration tests using Chinese hamster lung fibroblast cells (CHL cells) and monkey kidney cells (VERO cells), in vivo micronueleus tests using ddY mouse bone marrow cells and somatic mutation and recombination tests (SMART) using Drosophila melanogaster. The results of chromosome aberration tests in CHL cells showed no incidence of increased structural and numerical aberrations regardless of metabolic activation, while in VERO cells treated with 2.0, 1.0, 0.5, 0.3 ug/ml of ochratoxin A showed significant increase of structural aberrations without metabolic activation. Aspartame and-phenylalanine, structural analogs of ochratoxin A, didn't affect the chromosome aberrations induced by ochratoxin A. The in vivo induction of micronucleated polychromatic erythrocytes were measured in bone marrows of ddY mice treated with 10.0, 5.0, 2.5mg/kg/10ml of ochratoxin A through intraperitoneal route once. At 24 and 48 hours after treatment, ochratoxin A didn't induce micronuclei in bone marrows of ddY mice. And at the concentration of 40, 20, 10 ug/ml of ochratoxin A, which was administered by feeding to larvae of Drosophila melanogaster, showed no incidence of increased multiple wing hairs and flares. Summarizing all results, we concluded that ochratoxin A is a kidney cell specific direct genotoxicant.

Hyperplastic polyps are often multiple and by far the most frequent lesions among gastric polyps, contributing for about 90% of the polypoid lesions observed in the stomach. However, hyperplastic gastric polyposis is rare and was not exactly evaluated for natural course. These lesions are considered reactive and not genetically determined conditions. So it has been claimed that the hyperplastic polyps and hyperplastic polyposis are non-neoplastic lesions that result from regenerative hyperplastic reaction to inflammation and erosion. Recently we experienced a hyperplastic gastric polyposis with morphological changes during short follow-up period and reported herein.

The application of DNA typing method after amplification by the polymerase chain reaction (PCR) of DNA derived from bone from two missing persons. In this case, short tandem repeats (STR) are used. The AmpFlSTR Identifiler loci (amelogenin and 15 STRs) are analysed by multiplex-PCR and automated fluorescent detection using Perkin Elmer Prism 310 DNA sequencer.

Wegener's granulomatosis is a rare disease that pathologically causes necrotizing granulomatous vasculitis in the arterioles and venules and it can invade the whole body. In addition, it is difficult to distinguish between a nontuberculous mycobacteria infection that shows manifestations of granuloma and Wegener's granulomatosis. There has been no reported on a patient who had the 2 abovementioned two diseases at the same time. A 69 year old male patient had Wegener's granulomatosis that had invaded the prostate. He also had a scrotal swelling and back pain. He had manifestations of granulomatous infection on the scrotum and spine biopsies. However, there was no clinical evidence of Wegener's granulomatosis. As a result, we examined him for other diseases that can cause a granuloma. Consequently, he was also diagnosed as suffering with a nontuberculous mycobacteria infection. We report here on this case and we review the relevant medical literature.

AIMS: The left colon receives its arterial supply from the inferior mesenteric artery (IMA). The detailed anatomical understanding of IMA is important for sigmoid colon or rectal cancer surgery. The aim of this study is to investigate the vascular anatomy of the IMA by measuring the distance from the aortic bifurcation and the length of the IMA in autopsy cases. METHODS: 41 consecutive autopsy cases were enrolled prospectively. 29 cases were males and 12 females. Mean age was 47.7+/-15.6 with a range of 12 to 82 years. The distance from the aortic bifurcation is measured between the angle of abdominal aortic bifurcation and the inferior margin of the IMA. The length of the IMA is measured between the root of the IMA and the proximal border of the first branch of the IMA. Mann-Whitney U test, Pearson's correlation coefficient, and Spearman's rho were used for statistical analysis. RESULTS: The distance from the aortic bifurcation ranged from 3 to 6.3 cm with a mean of 4.4+/-0.71 cm. The length of the IMA ranged from 2.5 to 7 cm with a mean of 4+/-0.8 cm. The distance from the aortic bifurcation and the length of the IMA had no correlations with subject's height and weight. CONCLUSIONS: The vascular anatomy of the IMA in the general population is an important information for colorectal surgeon. Clear anatomical understanding of IMA may help perform oncologically safe colorectal surgery.

BACKGROUND: We present here the annual data of the intensive care unit (ICU) module of the Korean Nosocomial Infections Surveillance System (KONIS) from July 2010 through June 2011. METHODS: We performed a prospective surveillance of nosocomial urinary tract infections (UTI), bloodstream infections (BSI), and pneumonia (PNEU) at 130 ICUs in 72 hospitals using KONIS. Nosocomial infection (NI) rates were calculated as the number of infections per 1,000 patient-days or device-days. RESULTS: A total of 3,757 NIs were found: 1,978 UTIs (1,949 cases were urinary catheter-associated), 1,092 BSIs (with 932 being central line-associated), and 687 PNEUs (410 were ventilator-associated). The rate of urinary catheter-associated UTIs (CAUTIs) was 3.87 cases per 1,000 device-days (95% confidence interval, 3.70-4.05), and the urinary catheter utilization ratio was 0.86 (0.859-0.861). The rate of central line-associated BSIs was 3.01 per 1,000 device-days (2.82-3.21), and the utilization ratio was 0.53 (0.529-0.531). The rate of ventilator-associated PNEUs (VAPs) was 1.75 per 1,000 device-days (1.59-1.93), and the utilization ratio was 0.40 (0.399-0.401). Although both the ventilator utilization ratiosand the urinary catheter utilization ratios were lower in hospitals with 400-699 beds than thosein hospitals with 700-899 beds ormore than 900 beds, the rates of VAPsand CAUTIs were higher in hospitals with 400-699 beds than thosein hospitals with 700-899 beds or more than 900 beds. CONCLUSION: The risk of acquiring VAP and CAUTI is higher in the ICUs of 400-699 bed hospitals than in ICUs oflarger hospitals. Therefore, ongoing targeted surveillance and implementation of proven infection control strategies are needed especially for hospitals having fewer than 700 beds.

Extramedullary plasmacytomas most commonly occur in the nasal cavity, nasopharynx, paranasal sinuses, and larynx. Solitary extramedullary plasmacytoma (SEP) of the thyroid gland is rare. The diagnosis of SEP of the thyroid by cytology is typically difficult before surgery, and the entity is often confused with different cytology findings. We report a case of a 59-year-old man with primary plasmacytoma of the thyroid presented as a rapidly enlarging thyroid gland with Hashimoto's thyroiditis. He had been suffering from anterior neck swelling for 1 month. Several fine-needle aspiration biopsies yielded Hashimoto's thyroiditis. During a follow-up period of 3 years, the size of the thyroid gland increased and a mass lesion in right thyroid gland was detected. A total thyroidectomy was performed based on a diagnosis of a thyroid tumor with Hashimoto's thyroiditis. Permanent pathology identified the mass as an extramedullary plasmacytoma associated with Hashimoto's thyroiditis. Skeletal survey and serum electrophoresis tests were normal, and a bone marrow biopsy yielded no evidence of multiple myeloma. The patient underwent definitive radiotherapy and remained free from any recurrences during follow-up.
