In the past, arthrodesjs was a widely used procedure but in recent times, with the development of replacement arthroplasty, decreased in tuberculosis and polio. etc, it is not commonly used by orthopedic surgeons. However, for those in the young age group, people employed in hard labor and patients with acute inflammatory disease, arthrodesis is through to be more appropriate than replacement arthroplasty. From January 1980 to December 1985, 20 cases of arthrodesis of the knee joint were carried out. The results were follows.; 1. Methods of arthrodesis used were Charnley compression arthrodesis in 10 cases, Hoffman compression arthrodesis in 2 cases, cross pinning in 3 cases and and cross pinning with patella graft in 5 cases. 2. Bone union was seen in all 12 cases of compression arthrodesis at an average of 21.3 weeks while bone union was seen in 7 out of 8 cases of non-compression arthrodesis at an average 25 weeks. 3. Among the 20 cases, complication were pseudoarthrthrosis in one case, pin tract infection in 2 cases and skin necrosis in 5 cases. 4. Inconclusion of the above results, bone union was carried out in 19 cases out of total 20 cases, and compression arthrodesis showed faster bone union at an average of 3.7 weeks earlier than non-compression arthrodesis.

Two cases of Castleman's disease (Giant lymph node hyperplasia) are reported. The first case was a multicentric cervical giant lymph node hyperplasia. Excisional biopsy confirmed the diagnosis of Castleman's disease of the plasma-cell type. Despite repeated dissection of the cervical lymph nodes, complete removal of the lymph nodes was impossible, and the type was changed into mixed type, and regrowth of the tumor was noted. Prednisolone was of no benefit. The patient is now living with cervical masses in situ without general symptoms, 4 years after the initial diagnopsis. The second case was a solitary retroperitoneal giant lymph node hyperplasia, incidentally found. Complete excision was performed and biopsy confirmed the diagnosis of Castleman's disease of hyaline-vascular type. No recurrence was found at 2 years after the excision.

PURPOSE: It was well known that transforming growth factor (TGF)-beta1 plays a pivotal role in interstitial fibrosis and loss of podocyte. We explored the effects of exogenous administration of TGF-beta1 latency-associated peptide (LAP) in a model of renal fibrosis induced by unilateral ureteral obstruction (UUO) and examined whether TGF-beta1 LAP can inhibit apoptosis of podocyte. METHODS: Twenty four male BALB/c mice were unilaterally obstructed of proximal ureters by ligation. Half of the mice with operation and half of 8 control were administered recombinant human LAP intraperitoneally. One to three mice per group were euthanized on days 3, 7, 14, and 21 after operation for observation of renal fibrosis and apoptosis of podocyte. RESULTS: Interstitial fibrosis was less severe in LAP-treated group. Obstructed kidneys from LAP- untreated mice had more glomerular apoptotic podocytes (TUNEL assay) compared to LAP-treated mice at day 7, 14, and 21 after operation. CONCLUSION: Intraperitoneal administration of TGF-beta1 LAP prevents the loss of podocyte & renal damage partially up to day 14 after operation.

Pulmonary hamartoma is uncommon benign tumor-like malformation, which comprises abnormal mixing of the normal components of the lung i.e., cartilage, fat, smooth muscle or respiratory epithelium. The majority occurs in fourth and fifth decades of life, but extremely rare in the pediatric age. Pulmonary hamartoma is clinically classified to endobronchial and intrapulmonary hamartoma. The majority of the pulmonary hamartomas have no clinical symptoms and are detected incidentally by routine chest roentgenograms. But definite diagnosis should be necessary, because of its difficulty to differentiate from malignant and inflammatory lesions. We report a case of intrapulmonary hamartoma which was detected by routine chest roentgenogram check up and diagnosed by fine needle aspiration biopsy and pathological examination with the review of the literature.

PURPOSE: This prospective study was conducted to evaulate the effect of nebulized steroid (budesonide) and parenteral steroid (dexamethasone) on chidren with croup. METHODS: Twenty nine infants and children (6months-5years of age) admitted to hospital with croup were randomly assigned to receive either 1mg (4ml) of nebulized budesonide (17 patients) or 0.6mg/kg intramuscular injection of dexamethasone sodium phosphate (12 patients). Total croup score, heart rate and respiratory rate of patients were assessed on admission, 30 minutes, 2 hours, 6 hours, 12 hours and 24 hours after treatment, respectively. RESULTS: 1) In total cases, total croup score were significantly decreased at 30 minutes after treatment in the group treated with nebulized budesonide (p<0.01) but at 2 hours after treatmetn in the group treated with dexamethasone (p<0.05). 2) In mild cases (total croup score<5), total croup score were significantly decreased at 2 hours after treatment in the both group (p<0.05). 3) In moderate to severe cases (total croup score> or =5), total croup score were significantly decreased at 30 minutes after treatment in the group treated with nebulized budesonide (p<0.05). But in group treated with dexamethasone, there were no statistical significance because of small cases. 4) Respiratory rate was decreased after treatment in the both group, but significantly decreased at 2 hours after treatment in the group treated with dexamethasone (p<0.05). 5) Heart rate was decreased after treatment in the both group, but significantly decreased at 30 minutes after treatment in the group treated with dexamethasone (p<0.05). 6) There were no significant side effects in the both group. CONCLUSIONS: We conclude that both nebulized budesonide and parenteral dexamethasone were effective in treatment of croup, and that nebulized budesonide leads to more rapid clinical improvement in children with croup, especially moderate to severe one.

PURPOSE: To determine the time of magnetic resonance(MR) signal intensity changes in denervated skeletal muscle and to compare MR imaging with electromyography(EMG) in the evaluation of peripheral nerve injury. MATERIALS AND METHODS: We evaluated MR imagings of denervated muscles after experimental transection of the sciatic nerve in five rabbits using 1.0T MR unit. MR imaging and EMG were performed 3 days and 1, 2 and 3 weeks after denervation. T1-weighted images(T1-WI), T2-WI and Short Tau Inversion Recovery(STIR) images were obtained. The signal intensity (SI) of muscles in the denervated and normal sides were visually and quantitatively compared. After measuring the SI of the normal and abnormal areas, the time of SI change was determined when there was significant difference (P<0.05) of SI between the normal and denervated sides. RESULTS: On STIR images, two of the five rabbits showed significant SI changes at the third day(P<0.05) and all showed significant changes(P<0.05)at the first week. On T2-WI, one rabbit showed significant SI changes at the third day, and all showed significant SI changes at the first week. On T1-WI, significant SI changes were seen in one rabbit at the second week and in one at the third. One week after denervation, all showed denervation potential on EMG. CONCLUSION: This study suggests that MR imaging using STIR images is a useful method in the evaluation of denervated muscle, and that MR signal changes of denervated muscle may precede EMG changes after denervation. To localize and to determine the severity of the peripheral nerve injury, future analysis of the distribution of abnormal MR SI in denervated muscles would be helpful.

The incidence of lung cancer and its mortality rate are increasing in Korea. At the time of diagnosis, 40% patients of lung cancer patients had metastatic lesions. The common metastatic sites are the contralateral lung, bone, liver, adrenal gland and the brain. Metastasis to oral mucosa is rarely encountered in lung cancer and metastasis to the gingiva is more uncommon. Approximately 1% of malignant carcinomas in the oral cavity are the result of metastases, and 10-25% of metastatic cancers originate from lung cancer. Clinically metastatic gingival lesions are benign including hemangioma, pyogenic granuloma, giant-cell granuloma or a peripheral fibroma. Often metastases to the gingiva are diagnosed too late and by the time they are detected, they have metastases to other organs. Here we report a case of small cell lung carcinoma that had metastased to the gingiva with review of relevant literature.

Objective: Endometrial fibrosis, the primary pathological feature of intrauterine adhesion, may lead to disruption of endometrial tissue structure, menstrual abnormalities, infertility, and recurrent pregnancy loss. At present, no ideal therapeutic strategy exists for this fibrotic disease. Eupatilin, a major pharmacologically active flavone from Artemisia, has been previously reported to act as a potent inducer of dedifferentiation of fibrotic tissue in the liver and lung. However, the effects of eupatilin on endometrial fibrosis have not yet been investigated. In this study, we present the first report on the impact of eupatilin treatment on transforming growth factor beta (TGF-β)-induced endometrial fibrosis. Methods: The efficacy of eupatilin on TGF-β–induced endometrial fibrosis was assessed by examining changes in morphology and the expression levels of fibrosis markers using immunofluorescence staining and quantitative real-time reverse-transcription polymerase chain reaction. Results: Eupatilin treatment significantly reduced the fibrotic activity of TGF-β–induced endometrial fibrosis in Ishikawa cells, which displayed more circular shapes and formed more colonies. Additionally, the effects of eupatilin on fibrotic markers including alpha-smooth muscle actin, hypoxia-inducible factor 1 alpha, collagen type I alpha 1 chain, and matrix metalloproteinase-2, were evaluated in TGF-β–induced endometrial fibrosis. The expression of these markers was highly upregulated by TGF-β pretreatment and recovered to the levels of control cells in response to eupatilin treatment. Conclusion Our findings suggest that suppression of TGF-β–induced signaling by eupatilin might be an effective therapeutic strategy for the treatment of endometrial fibrosis.
