Identifying specific factors and/or mechanism regulating development of periodontal tissue will provide important information as to which molecules and cells are required for regulation of periodontal tissue lost as a consequence of disease. The origin and location of cementoblast and osteoblast precursor cells in adult periodontal tissues is not definitely known but it has been suggested that tooth related periodontal ligament may be the source of cementoblasts and the bone-related periodontal ligament for osteoblasts. However, little is known of the molecular mechanism controlling PDL function. PDL-specific protein; PDLs22 had been previously identified as a novel protein isolated from cultured human PDL fibroblasts using subtraction hybridization between human gingival fibroblasts and PDL fibroblasts. The aim of this study was to examine the functional characterization of PDLs22 in differentiation of periodontal ligament, alveolar bone and cementum. Human osteocalcin (OC), osteonectin (ON) and PDLs22 mRNA were detected by reverse transcription polymerase chain reaction (RT-PCR) in primary cell cultures of periodontal ligament fibroblast during mineral nodule formation in vitro. And the localization of PDLs22 in rat tissues was detected by polyclonal antibody against PDLs22 by means of immunohistochemical staining. The results were as follows: 1. PDL cells were capable of producing mineral-like nodules in vitro. 2. PDLs22 mRNA was expressed in the initial stages whereas it was not expressed in the calcification stage, during mineral nodule formation of PDL cells in vitro. 3. PDLs22 protein was expressed in external dental epithelium and stellate reticulum during crown formation stage, and was continued in external dental epithelium of Hertwig's epithelial sheath. Also PDLs22 protein was strongly expressed in the bone and cementum-related side of the PDL and weakly expressed in the middle of PDL. In the developing bone, PDLs22 protein is only expressed in preosteoblast not osteocyte and osteoblast. The results suggest PDLs22 is important mediator of epithelial-mesenchymal reaction in development of PDL, alveolar bone and cementum and is related to initial differentiation of cementum and alveolar bone.

Macrodactyly is one of the most difficult congenital anomalies to treat. Treatment of macrodactyly requires surgical intervention because it gives rise to esthetic, social, and functional disability including difficulty in wearing shoes. A myriad of surgical techniques has been introduced to reduce the size of macrodactyly. However, treatment of toe macrodactyly has not been spotlighted due to less significant functional and social issues compared with finger macrodactyly. We treated two patients with toe macrodactyly by single stage reduction operation.

Surgical treatment of congenital scoliosis is often frustrating due to its severity and rigidity. Many surgical methods were provided for these complex deformities and some instruments were used to achieve better correction. However, no surgical treatment was satisfactory to correct the deformities. Recently, pedicle screw fixation, enabling a powerful grip of individual vertebral segment, is becoming a promising method to enhance correction of these tenacious deformities. This study was to compare the correction, loss of correction and complications of the various surgical methods employed for congenital scoliosis in Seoul National University Hospital and to verify the advantages of pedicle screw fixation. Ninety-two congenital scoliosis subjected to surgery and followed up for more than 2 years(range 2-9 years) were analysed. Surgical methods were; anterior uninstrumented fusion, 5; posterior fusion, 50(14 without instrument, 15 with hooks, 21 with screws); combined anterior and posterior fusion, 37(7 without instrument, 11 with posterior hooks, 10 with posterior screws, 9 with anterior VDS and posterior screws). Mean preoperative magnitude of index curve was 58° with no significant difference between the groups except for the anterior VDS and posterior screw group which had a mean magnitude of 93°. Mean flexibility of index curve was 18.7% with no significant difference between groups. The correction of index curves were; anterior uninstrumented fusion, 23%; posterior uninstrumented fusion, 28%; posterior hook, 31%; posterior screw, 46%; combined anterior and posterior uninstrumented, 37%; anterior fusion and posterior hook, 30%; anterior fusion and posterior screw, 47%; anterior VDS and posterior screw, 48%. The correction of pedicle screws were significantly better(p < 0.01) with significantly smaller loss of correction(p < 0.01). Nonunion occurred in 4, 1 in posterior uninstrumented fusion, 2 in posterior hooks and 1 in posterior pedicle screws with concomitant instrument failures. However, there were no neurologic or visceral complications related to screw placement. Pedicle screw fixation offers an enhances correction of congenital scoliosis with low complication rate, and when combined with an anterior procedure, enables control of the most severe and rigid curves.

Corticosteroids are widely used in the treatment of various diseases because of its potent antiinflammatory effect. According to recent knowledge, bronchial asthma is also chronic inflammatory disease. Therefore antiinflammtory agent such as cromoyln sodium and corticosteroid is highly recommended for treament of chronic bronchial asthma. Especially hydrocortisone succinate (Solu-Cortef) is commonly used for treament. to acute .asthmatic attack via intravenous injection due to have rapid therapeutic onset and short duration. Since Sunaga et al. reported acute asthma attack after hydrocortisone injection in 1973, several cases of bronchospam with or without angioedema and urticaria after intravenous injection of hydrocortisone have been reported. We experienced a case of severe bronchospasm and acute respiratory failure after intraveous injection of hydrocortisone succinate in 64 year-old (tamale asthmatic patient who visited to emergency room for acute asthmatic attack. About 5 minites after Solu-Cortef injection, a severe bronchospasm with arterial hypoxemia was developed. In order to confirm the suspected relationship between the offending drug(Solu-Cortex and acute bronchospasm, we exacted intravenous and inhalation provocation test by hydrocortisone succinate and methylprednisolone (control). After administration of hydrocortisone succinate via intravenous and inhalation route, severe asthmatic attack occurred. But administration of intravenous methylprednisolone and orall triamcinolone and saline were not provoke bronchospasm. Skin test using hydrocortisone sodium succinate was also positive. Administration of hydrocortisone is very serious to asthmatic patient with hydrocortisone hypersensitivity. Therefore, the clinician must be have history taking about previous adverse reaction of steroid before its clinical use. And methylprednisone may be useful and safe drug to the treatment of acute asthmatic patient with hydrocortisone hypersensitivity.

OBJECTIVE: It was to analyze two failed arterial embolization cases in the treatment for pseudoaneurysm followed by D&C. METHODS: Two failure cases out of eight cases were gained in the transarterial embolization treatment for eight years.(1. 1. 1992 - 12. 31. 1999) To search for the factors of failure, we went through obstetrical history and biopsy. RESULTS: Eight cases of transarterial embolization were performed to the treatment for pseudoaneurysm appeared after undergoing D&C. Six cases were successfully treated without complications. However, laparotomy was done due to the continuous bleeding in the other two cases. According to tissue biopsy, they showed the cervical pregnancy in one case and placenta accreta in the other. CONCLUSION: Transarterial embolization is proved to be more preferable to operate in the treatment of pseudoaneurysm than laparotomy, and transarterial embolization therapy failure rate is higher in case of existing remnant villi than not.
