Lymphangioma is a benign tumor of lymphatic vessels. The majority of cases are present at birth and 95% of the tumors aroused before the age of 10 years. Oral lymphangioma may occur at various sites but are most frequent on the anterior two thirds of the tongue, where they often result in macroglossia. The lesions present nodularity with gray and pink projections. In the present cases, all the patients who had the macroglossia combined with lymphangioma showed openbite and mandibular prognathism. The purpose of this paper was to report the dental and craniofacial findings of macroglossia combined with lymphangioma and review the pertinent literature through the cases.

Objectives: To assess the functional outcome of Bankart repair and rotator cuff repair using miniopen technique in patients with recurrent shoulder dislocation(8 cases) with rotator cuff tears and Bankart lesion of over 40 years. Materials and Methods: From May 1991 to January 2002, twenty two patients were available to participate in the study. Mean age was 52 years old(41-67), Follow-up evaluations averaged 50.5months(10-147). Results: The patients(22 cases) were divided into two groups. Group 1: with recurrent shoulder dislocation(8 cases) with rotator cuff tears and Bankart lesion in patients over 40 years old. Group 2: without Bankart lesion(14 cases). In Group 1, mean average of forward flexion and abduction improved from 122 degrees to 154 degrees at the final follow-up and from 115 degrees to 161 degrees respectively. In terms of University of Pennsylvania patient self-assessment of pain score and VAS, scores improved from 11.0 to 5.5 and from 5.4 to 2.5 respectively. In terms of UCLA score & Constant score, scores also improved from 20.2 to 29.6 and from 48.6 to 69.0 respectively. Functional outcome of Group 1: two patients with excellent, four patients with good, and two patients with fair. Functional outcome of Group 2: two patients with excellent, six patients with good, five patients with fair, and one patient with poor. But they had no statistical significance between the two groups. All cases were improved shoulder pain at the final follow up. And six patients were satisfied with the outcome of shoulder function. Conclusions: This study demonstrates the effectiveness of Bankart repair and rotator cuff repair using miniopen technique in patients with recurrent shoulder dislocation(8 cases) with tears of rotator cuff and Bankart lesion older than 40 years. We recommend Bankart repair and rotator cuff repair at the same time.

An 80 year-old male with a medical history of angiosarcoma of the scalp visited the Emergency Department complaining of dyspnea, and the chest X-ray revealed pneumothorax. He has undergone scalp resection and radiotherapy three years ago due to angiosarcoma. Due to a persistent air leak, he underwent wedge resection of the lung and was pathologically diagnosed with metastatic angiosarcoma to the lung. He underwent radiotherapy following the lung resection, but he died from his disease at 15 month following surgery due to further aggravation of the lung metastasis. Angiosarcoma is a highly malignant tumor and it frequently occurs on the scalp and face in elderly patients. Angiosarcoma frequently metastasizes to the lung and it may cause pneumothorax as a consequence of a ruptured cavitary lesion. We report here on a case of pneumothorax that was caused by lung metastasis in an elderly patient with a history of angiosarcoma of the scalp.

Stromal tumors of the gastrointestinal tract, especially of the esophagus, are rare. We had a case of malignant gastrointestinal stromal tumor(GIST) of the esophagus. A 46 years old woman was admitted for abnormal mass shadow in the chest radiograph. The mass was originated from the lower thoracic esophagus, and compressed the right lower pulmonary vein and the inferior vena cava. We removed the tumor externally without injuring of the esophageal mucosa via right posterolateral thoracotomy. The tumor was positive for CD 34 and CD 117, and diagnosed malignant CIST of the esophagus.

Bulla is an air-filled space within the lung parenchyma resulting from deterioration of the alveolar tissue. Molecular mechanism of the formation of the bulla is not well described. Fibroblast growth factor(FGF)-7, bone morphogenetic protein(BMP) receptor, and transforming growth factor(TGF)-$\beta$ receptor are known to have a stimulatory or inhibitory role in the lung formation. We investigated to see if these growth factor or cytokine receptors are involved in the bulla formation by immunohistochemical staining of bullous lung tissues from patients with primary spontaneous pneumothorax. Material and Method: Bullous lung tissues were obtained from 31 patients with primary spontaneous pneumothorax, including 30 males and 1 female from 15 to 39 years old. The bullous tissues were obtained by video-thoracoscopic surgery and/or mini-thoracotomy and fixed in formalin. Blocks of the specimens were embedded with paraffin and cut into 5-6 ${\mu}{\textrm}{m}$ thick slices. The sections were deparaffinized and hydrated and then incubated with primary antibodies against FGF-7, BMP-RII, or TGF-RII. Result: Of the 31 patients, 24 were TGF-RII positive including 18 strong and 6 weak positives. Observation with high magnification showed that strong immunostaining was detected in the boundary region between bullous and normal lung tissues. In contrast, all of the sections were negative with FGF-7 or BMP-RII antibodies. Conclusion: These results suggest that overexpression of TGF- P RII may be involved in the formation of bulla, although further molecular studies are needed to find out more detailed molecular mechanisms.

Sericin hydrolyzing enzyme, produced by the selected bacteria, S4-1-1, was studied and following properties were obtained. 1. The activity of this bacterial sericinase was not decreased for 30 days of storage at $5^{\circ}C$. But at $20^{\circ}C$, for 30 hrs. was the maximum period to keep the initial activity of this enzyme. 2. This bacterial enzyme gave only sericinase activity but never indicated fibroin hydrolyzing activity. 3. The chelating reagent of EDTA and Ag or Hg ions were classified as strung inhibitors but Cu and Cd ions were indicated as moderate inhibitors to this enzyme action. 4. This enzyme was not inhibited by the surface active agent, Peretex-N, but strongly activated by this agent at low concentration. In the other hand, by the application of this enzyme to the unwinding works on the mulberry cocoon, the following results were also obtained. 1. On the weight and length, nonbreaking Length, size, colour and unwinding ratio of have, the enzyme appling method was superior to generally used cooking method. 2. The tested results of strength and elongation, bouchon, haririness loops, neatness and evenness of have were also indicated spuerior properties.

This experiment was conducted to know the effects of abnormal cocoons on the silk quality during the silk reeling process. The results obtained are summarized as follows: 1. The length, the width, the weight, the layer weight, and the layer ratio of abnormal cocoons are in every case 0.83∼4.65% less than those of normal cocoons. 2. The thickness of the abnormal cocoon layer is at)out 20.62∼22.4% less than that of the normal cocoon. 3. The sericin solubility of tile abnormal cocoon layer is about 11.75∼30% more than that of the normal cocoon layer. 4. The degumming ratio of the abnormal cocoon layer is about 6.51∼9.32% more than that of the normal cocoon layer. 5. The length of a have, the weight of a tave and percentage of raw silk yield of the abnormal cocoon are decreased 9.43%, 8.53% and 6.72% each as compared with those of the normal cocoon. 6. The percentage of reelability of abnormal cocoons is decreased 9.58％ as compared with that of normal cocoons. 7. The neatness of abnormal cocoons is 3 per cent lower than that of normal cocoons. 8. In the cleanness test of abnormal cocoons, the number of split ends i9 about 1.5∼3.8 times as much as that of normal cocoons. Especially cleanness of abnormal cocoons is 16,3 per cent lower than that of normal cocoons. 9. The number of non-reelable cocoons of abnormal cocoons is increased 1.4∼5.5 times as much as that of normal cocoons. In abnormal cocoon, the number of knot which resulted in the breaking of silk end is increased 1.9∼3.5 times as much as that in normal cocoon.

Purpose: Lymphonodular hyperplasia of the colon (LNHC) is a rare finding in children and its significance as a pathologic finding is unclear. The aim of this study was to investigate the clinical significance of LNHC by analyzing clinical and histopathologic findings in children with LNHC. Methods: We analyzed data from 38 patients who were confirmed to have LNHC by colonoscopy. We checked age, birth history, past history, family history, and clinical symptoms. A hematologic exam, stool exam, and image studies were performed and biopsy specimens were examined by a pathologist. All patients were asked to have short- and long-term follow-up. Results: The mean age of the patients was 12.5${\pm}$14.4 months. All patients presented with complaints of bloody stool. They appeared healthy and the hematologic findings were within a normal range, with the exception of one case. There was no other identified source of bleeding. On histologic exam, 36 patients (94.7%) had lymphoid follicles and 34 patients (84.5%) fulfilled the criteria of allergic colitis. Regardless of diet modification and presence of residual symptom, there was no recurrence of bloody stool through long-term follow-up in all patients. Conclusion: LNHC is more common in infants who are affected by allergic colitis, but it can appear even after infancy. LNHC should be regarded as the etiology when there are any other causes of rectal bleeding, especially in healthy children. We suggest that LNHC has a benign course regardless of diet modification and it might not require excessive concerns.

Purpose: We evaluated the sensitivity of the F-18 FDG PET by visual assessment and statistical parametric mapping (SPM) analysis for the localization of the epileptogenic zones in frontal lobe epilepsy. Materials and Methods: Twenty-four patients with frontal lobe epilepsy were examined. All patients exhibited improvements after surgical resection (Engel class I or II). Upon pathological examination, 18 patients revealed cortical dysplasia, 4 patients revealed tumor, and 2 patients revealed cortical scar. The hypometabolic lesions were found in F-18 FDG PET by visual assessment and SPM analysis. On SPM analysis, cutoff threshold was changed. Results: MRI showed structural lesions in 12 patients and normal results in the remaining 12. F-18 FDG PET correctly localized epileptogenic zones in 13 patients (54%) by visual assessment. Sensitivity of F-18 FDG PET in MR-negative patients (50%) was similar to that in MR-positive patients (67%). On SPM analysis, sensitivity decreased according to the decrease of p value. Using uncorrected p value of 0.05 as threshold, sensitivity of SPM analysis was 53%, which was not statistically different from that of visual assessment. Conclusion: F-18 FDG PET was sensitive in finding epileptogenic zones by revealing hypometabolic areas even in MR-negative patients with frontal lobe epilepsy as well as in MR-positive patients. SPM analysis showed comparable sensitivity to visual assessment and could be used as an aid in the diagnosis of epileptogenic zones in frontal lobe epilepsy.
