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.
