2.Clinical Application of a Multiple Splint Method for Inuries of Bone and Joint
The Journal of the Korean Orthopaedic Association 1986;21(5):837-843
Object of treatment of long bone fracture is the reduction of fracture and maintenance of good alignment. Recently operative treatment has been attempted increasingly, but conservative treatment is considered important also. The authors have employed the multiple splint method that is modified from triangular splint method for humerus shaft fracrure originally having designed and reported by ourselves. In our experience of multiple splint method for long bone fracture and ligament injuries, some merits were noticed such as easiness of application, simplicity of removal and reapplication. We report this method with review of literature.

Pigmentary dermarcation lines are boundaries between more deeply pigmented skin and areas of lighter pigmentation. We report 4 cases of pigmentary demarcation lines of pregnancy associated with erythema which developed in the third trimester of pregnancy and were symmetrically located in the buttock and posteromedial portion of the lower extremities. After delivery, the erythema disappeared within 3-7 days, followed by slow resolution of the brownish pigmentation.

One hundred patients of osmidrosis were treated by surgical procedure at the Department of Dermatology, Wonkwang University Hospital. The methods of operative treatment were elliptical excision for 37(74), bipedicle incision with apocrine glancl undercutting for 14(28), and single incision wit.h apocrine gland undercutt,ing for 49 (98). The results were summarized as follows : 1. Of the 74 axillae treated by elliptical excision, one occurred recurrence, and 1.7 showed complication, hematoma in 6, infection and delayed union in 4, each necrosis and severe scar in one each, 2. Of the 28 axillae treated by bipedicle incision with apocrine gland undercutting, 6 showed complication; hematoma in 4, infection and delayed union in one each 3. Of t..he 98 axillae treated by single incision with apocrine gland undercutting, 5 showed complication, hematoma in 3, infection and delayed union in one each In conclusion, single incision with apocrine gland undercutting was found to be more excellent compared with the other surgical methods.

Recently, surmountable amounts of genes are being cloned without information about them and it has become neccessary to develop new techniques for discovering genes with more informaiion like as chromosomal location and possible functions. We have developed one such a method and applied it to search for genes that may be related with the neural development. The mRNAs were extracted from cerebral cortex of 18 week old human fetus, cDNAs were made by reverse transcription from these mRNAs and Uni-amp cDNAs having Uni-amp adapters at both ends were made for subsequent PCR. To observe the distribution of the Uni-amp cDNAs on the chromosome, fluorescent in situ hybridization was performed with biotin labeled Uni-amp cDNAs. Among the chromosome bands showing strong hybridization with the cDNAs, 7q22 was microdissected from the chromosome hybridized with unlabeled Uni-amp cDNAs and amplified by PCR with Uni-amp primers. These amplified cDNA fragment were subcloned to vectors and the nucleic acid sequences were analysed. As a result, 46 different clones were obtained. They were categorized as 12 clones of well characterized genes, 14 clones showing low homology with known genes, 13 clones of simply registered uncharacterized human cDNAs, 7 clones of unknown genes. In situ hybridization histochemistry of 34 novel genes, except 12 known genes, were performed on developing and adult rat tissue sections to see the tissue specificity and developmental expression of these genes. The expression of several novel genes were restricted to the nervous system. From these results, it may be suggested that our technique is very useful to clone the genes expressed in the developing human braine with confirmed chromosomal location. In addition, this cloning technique can be used to discover the new genes related with neural development in combination with functional screening methods.

We experienced a case of simple pneumonediastinum showing the findings of pleural effusion. Frontal chest radiography showed not only pneumomediastinum but also diffuse haziness with sharp medial margin on left lower lung field, blunting of costophrenic angle, and indistinct contour of diaphragm simulating pleural effusion. CT scan confirmed that these findings arose from the displaced pleura and the associated compression atelectasis by loculated air on the anterior mediastinum.

OBJECTIVE: Evaluation of embryos using early cleavage to 2-cell stage has been proposed, but a critical time-point for selecting embryos is unclear. The aim of the present study is to provide a guideline including critical time-point in the selection of early cleaving embryo for the reduction of multiple pregnancies as well as the increase of pregnancy rate in human IVF. METHODS: This prospective study was performed in 116 cycles from 85 patients who underwent conventional IVF or ICSI at the infertility clinic of Good Moonhwa Hospital from January 2002 to December 2003. Early cleavage (EC) of embryos to 2-cell stage was assessed at 25 h and 27 h postinsemination/microinjection. Embryos that had early cleaved at each time point were designated as EC-1 and EC-2, respectively, while others were designated as non-early cleavage (NEC). RESULTS: At least one early cleavage embryo was observed in 54 (46.6%) for the EC-1 and 84 (72.4%) for the EC-2 of the 116 cycles assessed. Clinical pregnancy rates (PR) were significantly higher in the EC-1 group (66.7%) compared to the EC-2 group (53.6%) or the NEC group (31.2%) (p<0.05). Significant improvement of the pregnancy rate was found when at least two or more embryos were early cleaved at 25 h postinsemination or when the proportion of early cleavage embryo at 25 h postinsemination was higher than 20% (p<0.05). CONCLUSIONS: The critical time-point for the selection of early cleavage embryos with high implantation potential is more effective in 25 h postinsemination/microinjection compared to 27 h. The proportion as well as number of early cleavage embryos is also an important factor for the prediction of pregnancy outcome and the chance of multiple pregnancies. These results demonstrated that the evaluation of early cleavage embryos to 2-cell stage is an easy, simple, and objective method for the selection of good quality embryos suitable for embryo transfer.

E-cadherin is a calcium-dependent epithelial adhesion molecule which plays a role in the initial step of invasion of cancer cells. The step that follows the migration of separated tumor cells is a proteolytic lysis of basement membrane and extracellular matrix by protease of epithelial and endothelial cells such as matrix metalloproteinase (MMP). Vascular endothelial growth factor (VEGF) is known to be an endothelial cell-specific powerful mitogen as well as a vascular permeability factor. This study is aimed to evaluate the correlation between expression of these factors and pathologic or clinical variables and the roles and prognostic significance of those factors in squmous cell carcinoma and adenocarcinoma of the lung. Immunohistochemical stains were performed for E-cadherin, MMP-2, and VEGF in surgically resected specimens from 90 patients with squmous cell carcinoma and adenocarcinoma of the lung. Mean age of the patients was 59.7 years. Histologic type was categorized into 56 cases of squamous cell carcinoma and 34 cases of adenocarcinoma. Mean survival period of the 35 patients was 54 months. The immunohistochemical stains for E-cadherin, MMP-2, and VEGF revealed positive reaction in 67 cases (74.4%), 43 cases (47.8%), and 34 cases (37.8%), respectively. The expression of E-cadherin was higher in adenocarcinoma (82.4%) than in squamous cell carcinoma (69.6%). MMP-2 was expressed in the tumor cells, especially those invading into the surrounding stroma. The expression of MMP-2 was significantly correlated with the survival rate (p<0.05). The expression of VEGF in the tumor cells was significantly higher in cases with lymph node metastasis (p<0.05). In conclusion, these findings suggest that the expression of MMP-2 and VEGF predict poor prognosis of patients with squmous cell carcinoma and adenocarcinoma of the lung and that VEGF may play a role in tumor metastasis.
