Immunohistochemical study was performed for CEA staining patterns and PCNA indices. And the relationship between immunohistochemical findings and well-known clinical prognostic factors on the purpose of the clinical usefulness was evaluated. In forty seven cases of surgically removed colorectal carcinomas, the results were as follows; CEA staining patterns were apical (17 cases) and cytoplasmic (30 cases) type. Carcinomas with cyto plasmic pattern for CEA revealed more advanced Dukes' stage and more undifferentiated type and higher incidence of lymph node metastasis and were correlated with increased serum CEA levels. But PCNA indices showed no correlation with the Dukes' stage, histologic grade and CEA staining patterns. The cytoplasmic pattern of CEA immunohistochemistry may be a useful marker suggesting more aggressive biologic behavior of the colorectal carcinomas.

In situ hybridization (ISH) is a standard method for localizing DNA or RNA sequences in tissue or cell preperation. The technique was developed at the electron-microscopic level, and enables the precise subcellular localization. A method was developed for detection of specific viral DNA. We have tested various methods and technique to detect specific viral DNA through ISH at the electron microscopic level. Postembedding method of ultrastructural ISH was developed and successfully applied for the detection of human papillomavirus type 16 in squamous cell carcinoma of the uterine cervix and Epstein-Barr virus in EBV-infected leukemia cell line. The following results are made. The best results were obtained using 0.2% glutaraldehyde and 4% paraformaldehyde fixed tissue or cell block. The labelling was best observed on Unicryl resin and Lowicryl K4M resin sections. Epon sections showed no reactivity. Thin sections of Unicryl resin were more easier than Lowicryl K4M resin. Enzymatic predigestion with proteinase K, pepsin and trypsind gave good results. However, high concentration of these produce poor results due to excessive destruction of the cellular components. Alkali treatment with 0.5N sodium hydroxide produced successful results in denaturation of target DNA. The labelling density of gold particles was independent of incubation time or temperature in hybridization step. The viral DNA labelling was localized mainly within the nucleus, both within and at the edge of electron dense regions, and below the nuclear membrane. And the labelling was seen in the form of a dense, roughly spherical shape. In conclusion, the best results are obtained by the conditions that tissue fixed by 0.2% glutaraldehyde and 4% paraformaldehyde solution, embedded with Unicryl resin, protein denaturation by 0.1ul/ml proteinase K, DNA denaturation by 0.5N sodium hydroxide, and reaction with DNA probe.

Benign symmetric lipomatosis is characterised by diffuse symmetric deposits of adipose tissue, predominantly on the neck, shoulder, back and upper extremities. We report a case of benign symmetric lipomatosis in a 61-year-old-man, which was first noted one year previously. It began growing rapidly about 3 months ago and was associated with alcoholic liver disease. Histopathological findings showed that the reticular dermis had been replaced by normal uncapsulated mature fat cells that were slightly increased in number in the fibrous connective tissue. He was treated with theophylline 300mg/day for two months.

Chronic eosinophilic pneumonia is a rare diasease characterized by chronic infiltration of the lung with ~eosinophils, usually associated with peripheral eosinophilia. In 65% of cases, the chest rad Ogroaph shows typiical nonsegmental air-space consolidation confined to the outer third of the lung and in 25)/0 of case "photographic negative of pulmonary edema". Typical lung manifestations with 'peripheral eosinophiliSa' tahrcharacteristic of chronic eosinophilic pneumonia. In the remaining cases, radiographic findings are nonspecific and require lung biopsy for confirmation. We repot a case of chronic eosinophilic pneumonia in which chest radiograph and CT scans revealed bilateral patchy or diffuse opacity with nodules scattered throughout the lungs.

BACKGROUND: The purpose of our study was to evaluate the functional and radiologic outcomes of additive augmentation sutures through rotator cuff for proximal humeral fractures stabilized locking plate in elderly patients. METHODS: We enrolled 74 patients over the age of 60 years who received internal fixation using locking plates for proximal humeral fractures. Of these, 50 patients had additive augmentation sutures through rotator cuff. The mean age at the time of surgery was 72.1 years (range, 60-89 years), and the mean follow-up period was 17.5 months (range, 12-62 months). The humeral neck-shaft angle and humeral head height were used as radiological markers to assess the effect of additive augmentation sutures through rotator cuff. We allocated the patients who received additive augmentation sutures into group A and those who did not into group B. RESULTS: At the final follow-up, the mean Korean Showlder Society score and Constant scores were 88.96 +/- 12.1 and 86.6 +/- 11.9, respectively, in group A and 86.21 +/- 11.8 and 85.3 +/- 11.7, respectively, in group B (p=0.368, 0.271). At the final follow-up, the mean loss in humeral neck-shaft angle from the time of immediate postoperative measurement was 1.6degrees in group A and 4.8degrees in group B, whereas the mean loss in humeral head height was 0.82 mm in group A and 0.52 mm in group B (p=0.029, 0.178). CONCLUSIONS: The surgical outcomes of internal fixation using locking plates for proximal humeral fractures were clinically and radiologically good in elderly patients over the age of 60 years without any observable complications. Further, the loss of humeral head shaft angle at the final follow-up from its initial postoperative measurement was significantly smaller in patients who received an additive augmentation suture than in those who did not. Thus, we conclude that augmentation sutures are a beneficial option for elderly patients that clinicians can consider at the time of surgical decision making.

One of the complication during or after subclavian vein cannulation is intravascular catheter or wire embolization. Although some studies have reported safety of retaining foreign body embolization, and even death. The intravascular foreign body can be removed surgically or non-surgically. With improvement in instrument technology and technique, percutaneous retrieval of intravascular foreign bodies has become a relatively common procedure. Commonly used methods to remove intravascular foreign bodies are loop snare and basket technique. Sometimes biopy forcep can be used. We have experienced 2 cases of non-surgical removal of intravascular foreign bodies. One of the foreign bodies was 7cm wire fragment in right atrium(RA), the other was a 50cm guide wire. We used the standard loop snare technique for removal of 7cm wire fragment in RA and stone removal basket and 3.0mm ACS PTCA balloon to remove the 50cm short guide wire.
