The main goal for the treatment of periodontal diseases is the regeneration of lost cementum, bone and connective tissue. Clinical and histological research suggests that it is possible to restore periodontal structures. Seeds of Carthamus tinctorius L. has been used for the treatment of bone fracture and osteoporosis in traditional Korean medicine. The purpose of this study is to examine the effect of extract of seeds of Carthamus tinctorius L. on mineralization in periodontal ligament cells and osteoblastic cells. Periodontal ligament cells were primarily obtained from a extracted premolars with non-periodontal diseases. Osteoblastic cells were obtained from calvariae of a fetal rat. Cells were cultured with DMEM at 37degrees C with 5% CO2 in 100% humidity incubator. Alkaline phosphatase(ALP) level and the number of calcification nodules were examined and western blot analysis using osteonectin was performed. Measurements of ALP levels and calcification nodules showed that extract of seeds of Carthamus tinctorius L. had significantly higher activity than control in all of both cells. In western blot analysis, protein expression of osteonectin indicated that extract of seeds of Carthamus tinctorius L. showed an increased pattern than control in all of both cells. From the above results, it seems that extract of seeds of Carthamus tinctorius L. has excellent effect on mineralization in periodontal ligament cells and osteoblastic cells.

Chusid et al proposed diagnostic criteria of hypereosinophilic syndrome (HES) that remain valid today. These were, (1) a sustained peripheral blood eosinophil count of more than 1500/L present for longer than 6 months ; (2) no evidence of other apparent causes for eosinophilia, and (3) presumptive signs of parenchymal organ involvement. Any organ system may be affected in HES, but the most severe clinicopathological involvements are of the heart and nervous system. Although multiple organ systems may be involved, the most common cause of morbidity and mortality is cardiac involvement with extensive fibrous thickening of the endomyocardium and overlying thrombus. We report a case of acute peri-myocarditis with eosinophilia, which was confirmed as eosinophilic myocarditis by endomyocardial biopsy, with literature review.

BACKGROUND: Sorbitol fermenting Escherichia coli O157 were reported. And E. coli O157:H7 produce various Shiga toxin (Stx) such as Stx1, Stx2, or variants of Stx2. In this study, we tried to establish laboratory methods that detect E. coli O157:H7 quickly and precisely by analyzing sensitivity of colony hybridization test and PCR technique. METHODS: Stx1-producing E. coli ATCC 43890, Stx2-producing E. coli ATCC 43889, and Stx2vha- producing E. coli ATCC 51435 were tested. Three strains of E. coli were diluted with 0.1 g of diarrheal stools from 107 CFU to 101 CFU respectively. The stool samples were incubated overnight in MacConkey agar plates. A mean of 63 colonies were hybridized by stx1- and stx2-specific oligonucleotide probes. PCR for stx1 gene and stx2 gene was done after overnight- incubation of stool samples in the LB broth with vancomycin (6 ug/mL). Positive colonies by colony hybridization were confirmed by PCR for stx1 gene and stx2 gene. RESULTS: Colony hybridization test could detect Stx1-producing E. coli at 103 CFU per 0.1 g of stool, Stx2-producing E. coli at 105 CFU per 0.1 g of stool, and Stx2vha-producing E. coli at 104 CFU per 0.1 g of stool. PCR technique after enrichment in LB broth with vancomycin (6 ug/mL) could detect stx1-, stx2-, and stx2vha-containing E. coli at 10 CFU per 0.1 g of stool respectively. CONCLUSOIN: A combination of colony hybridization and PCR after enrichment in broth with vancomycin (6 ug/mL) is useful for the rapid and precise diagnosis of infections of Shiga toxin-producing E. coli O157:H7.

Healing of periodontal tissues require the migration and proliferation of gingival fibroblasts and periodontal ligament cells. There is many evidences that the some agents like cytokines and polypeptide growth factors are mediate these cellular events in wound healing. Recently someone is interested in herbal drugs on periodontal tissue healing processes. The purpose of this study was to examine the effects of 4 herbal drugs, Carthami Flis, Moutan Radicis Cortex, Scirpi Rhisoma, Seed of Carthamus tinctorius L. on human gingival fibroblasts and periodontal ligament cells. Periodontal ligament cells and gingival fibroblasts were primarily cultured from extracted premolar with non-periodontal diseases. The powder from extracted herbal drugs were prepared with distilled water. Cells were cultured with DMEM at 37degrees C, 5% CO2, 100% humidity incubator, and treated with each herbal drugs with proper concentration for 1, 2, and 3 days. The cell activity was determined by ELISA reader using MTT assay. There was the most significant elevation in 10(-3)g/ml of almost herbal drugs on cellular activities. The result of this study demonstrated that Carthami Flis, Moutan Radicis Cortex, Scirpi Rhisoma, Seed of Carthamus tinctorius L. appears to have beneficial effect on healing process after periodontal treatment.

Malignant fibrous histiocytoma is a rare malignant tumor of probably histiocytic origin. It is more common in soft tissue than bone. Usually it involves metaphysis or diaphysis of long bone. Primary spinal malignant fibrous histiocytoma is exceedingly rare. Authors report a case of primary malignant fibrous histiocytoma which showed rapid spinal cord compression in thoracic spine with review of literatures.

Enterogenous cyst is a rare cause of spinal cord compression. It is resulted from dysembriogenetic error developed at the third week of the embryo life. A case of 17-year-old male with an intradural extramedullary enterogenous cyst of the cervical cord is presented. In appeared as a mass of low-intensity signal in comparison with the spinal cord on magnetic resonance imaging. Histologically, it was confirmed by epithelium which was composed of single pseudostratified mucus-secreting cuboidal or columnar cell with hyalinized fibrous wall. Total removal was possible without complications. The clinical and radiological findings and it's morphogenesis are discussed with a review of the literature.

BACKGROUND: The purpose of this study is to define the risk factors of S. epidermidis acquisition and the epidemiology of strain variation in acute leukemia patients. METHODS: The participants were 155 patients of acute leukemia admitted in a University hospital for 11 months. 83 patients are the isolated group who had isolated S. epidermidis from body sites (blood, oral cavity, nares, rectum) and 72 patients are the not isolated group who had not isolated S. epidermidis. Isolates were analysed by CHEF and cluster analysis with dendrogram. Differences In proportions were tested with the Chi-square and Fisher's exact test. RESULTS: Ninety-one S. epidermidis were obtained from blood, oral cavity, nares, and rectum. The major proportion of positive culture was 81.3% from nares. Eight-nine S. epidermidis were isolated from healthcare workers. There were significant development of bacteremia in patients with S. epidermidis from nares. Resistance rate of S. epidermidis was 75.8% to methicillin, 86.3% to erythromycin, 81.l% to gentamicin, 68.9% to ciprofloxacin, 0% on vancomycin. There was significant difference on resistance rate between patients and healthcare workers' group. There was no relation between the strain of patients and those of healthcare workers. Sex age, diagnosis, length of stay, type of chemotherapy, duration of chemotherapy, Type of central venous catheter. duration of central venous catheter, prior antibiotic therapy, number of antibiotics, site of nosocomial infection, neutropenic period were not significantly different between S. epidermidis isolated group and not isolated group. Significant risk factors included duration of central venous catheter. hyper-alimentation, and folliculitis. CONCLUSION: Our result suggests that S. epidermidis in nares can be a risk factor of bacteremia. This research would be helpful for decreasing the S. epidermidis of immunocompromised patients.

The purpose of this study was to investigate the effects of smoking on adult periodontitis after non-surgical periodontal therapy. The study population consisted of 40 patients with moderate to advanced periodontitis. Smokers(n=20) were defined as individuals smoking at least twenty cigarettes per day at the time of the initial examination. The non-smoking group(n=20) consisted of individuals who were not smoking at the initial examination. The average age was 42.4 years for the smoking and non-smoking group. Examination regarding plaque index, gingival index, pocket depth and contrast phase microscope were performed. Evaluation were made at the first, the second and the fourth weeks after periodontal non-surgical therapy. The results were as follows: 1. Clinical indices including plaque index, gingival index, and pocket depth were decreased in both smoking and non-smoking group at the first, the second, and the fourth weeks. Especially, clinical indices of non-smokers were more significantly decreased than those of smokers. 2. Non-motile rods were increased and motile rods were reduced at the fourth week. spirochetes were reduced significantly in the non-smoking group at the fourth week. These results suggest that smoking play a minor role in adult periodontitis after non-surgical periodontal therapy.
