Diabetes is a metabolic disease, leading to high blood glucose levels, and oral complications were as follows : cheilosis and a tendency toward drying cracking : burning sensations : decrease in salivary flow : alterations in the flora of the oral cavity with greater predominance of Candida albicans : and increased periodontal disease. The increase susceptibility of diabetics to infection has been well known. The cellular and humoral immune systems also require accessory cells, such as macrophages and antigen-presenting cells, for an optimal response to occur. Male rats weighing about 150-200 gm were induced to diabetes by streptozotocin, and were serially sacrificed on the 1st, 2nd, 3rd day and 1st, 2nd, 6th week of experiment. And then histologic examination on the cervical lymph node & S-100 protein positive dendritic cell were carried out under th light microscope. The results of this study were as follow : 1. In control group, cevical lymph node consists of a capsule, cortex, paracortex, medullary sinus and medullary cord. The germinal centers appear in the cortex. The medullary cord was composed of closely packed lymphocytes, and the medullary sinus was full of lymph. In the features of immunohistochemical stain, S-100 protein positive cells were seen in the germinal center. 2. In the 1 day experimental group, the germinal centers were more smaller than that of control group and most of them disappeared. The medullary cord was composed of loosely packed lymphocytes. In the features of immunohistochemical stain. S-100 positive protein cells were decreased and somewhere negative. 3. In the 3 day experimental group, it is similar to 1 day finding but the germinal center had clear margin than that of 1 day experimental group. In the features of immunohistochemical stain, the number of S-100 protein positive cell was decreased and somewhere negative. 4. In the 1 week experimental group, the germinal center was more clear than that of 3 day experimental group and T lymphocytes were scattered in the paracortex. In the medullary cord, density of lymphocyte was more increased. In the immunohistochemical stain, S-100 protein positive dendritic cells were increased in the margin of germinal center and somewhere negative. 5. In the 2 week experimental group, the germinal centers were more recovered. In the medullary cord, density of lymphocyte was increased. In the immunohistochemical stain, S-100 protein positive dendritic cell were increased in the germinal center. 6. In the 6 week experimental group, histologic pattern of cortex and paracortex was similar to control group finding, in the immunohistochemical stain, somewhere the number of S-100 protein positive dendritic cell was similar to control group. From above results, in the streptozotocin induced diabetic rat, as the germinal center of cervical lymph node were decreased and antigen-presenting cell, dendritic cell was affected, the function of cervical lymph node, which was responsible for maxillofacial immune system, was decreased.

Thymic carcinoid or neuroendocrine tumor of thymus is a very rare disease and has poor prognosis due to frequent recurrence and distant metastasis. A 43-year-old man was refered to our hospital because of Rt. chest pain and tightness. Chest X-ray revealed 7 X 8cm sized mass on Rt. anterior mediastinum. Surgical excision was performed and light microscopic, immunohistochemical and electron microscopic findings were confirmed as atypical thymic carcinoid tumor with thymic cyst. The patient has been followed up without recurrence or distant metastasis postoperatively for 3 months to now. We report a case of atypical thymic carcinoid with thymic cysts.

PURPOSE: Surgical excision of the subcutaneous tissues, with or without skin excision in the axillary hair-bearing area, has been the treatment of choice in treating osmidrosis for several decades. However, long periods of postoperative immobilization of a shoulder joint, partial necrosis of skin flaps or the possibility of hematoma and scars have occurred frequently. So we used XPS(R) microresector(Shaver) in procedure which requires removal of soft tissue for comparing results between surgical excision and the laters. METHODS: From January 2007 to February 2008, a total of 20 patients(8 male and 12 female) underwent XPS(R) microresector(Shaver) assisted aspiration for treating osmidrosis. The mean age of the subjects was 21.9, and we tried to analyze some advantages of XPS(R) microresector(Shaver). RESULTS: The average operation time was 61.6 minutes. This results can show that the patients who received XPS(R) microresector(Shaver) assisted aspiration can accomplish better outcomes than any other procedures in terms of operation time at least. Moreover, no significant postoperative complications occurred in our studies. Subjects have been followed up from 2 months to 1 year and among these patients, no one suffered from critical complications. CONCLUSION: In brief, XPS(R) microresector(Shaver) is able to shorten the time of operation and simplify the procedures relatively and this device has more superiorities in wound healing by maintaining of vascularized dermal skin flaps. It means that XPS(R) microresector (Shaver) can prevent flap necrosis, axillary hair loss and minimalize scarring and bleeding. Thus, we expect that these advantages can lead to better patient's comfort and self-confidence than several previous procedures.

Cyclooxygenase (COX) is an enzyme involved in the conversion of arachidonic acid to prostaglandins(PGs), and exists in two forms, COX-1 and COX-2. COX has been reported to be involved in early implantation by secretion of PGs which causes permeability of vessels and reaction of decidual cells around the implantation site. Recently, in mice and sheep studies, COX-1 and COX-2 expression in the endometrium has been reported to be different according to implantation and stages of the estrous cycle, but expression of COX-1 and COX-2 in human endometrium during the menstrual cycle has not yet been established. The purpose of this stuffy was to observe the variances of COX-1 and COX-2 expression by immunohistoehemical staining in endometrial samples obtained from human hysterectomy specimens and biopsies of women of reproductive age according to different stages of the menstrual cycle. Also, we attempted to observe COX-1 and COX-2 expression in the epithelial and stromal cells of the endometrium obtained during the mid-secretory phase, which were cultured separately. COX-2 showed a cyclic pattern of expression according to the different stages of the menstrual cycle and was strongly expressed particularly at the mid-secretory phase which corresponds to the time of implantation. However, COX-1 tended to be increased in the early proliferative, and mid- and late secretory phases, but was also expressed in the whole menstrual cycle showing no particular pattern. In the separately cultured cells COX-1 was expressed in epithilial cells and COX-2 in the stromal cells. The above results suggest that since COX-2 is expressed at the same time as implantation and cultured cells display a specific secretory pattern, COX-2 has inductive endocrine enzyme properties and has an important effect on endometrial cells during implantation. Also, COX-2 expression in endometrial cells may be utilized as a useful marker of endometrial maturation.

Secondary esophageal carcinoma usually originates from a primary site in either the lung or breast. Only one case of metastatic esophageal cancer with a radiologic evidence that it was originated from the rectal cancer had been reported. We report an unusual case of a 80-year-old man with secondary esophageal carcinoma originated from the rectal cancer. It was diagnosed by histopathologic confirmation using immunohistochemical staining including CK20 and CK7 by comparing the histopathologic findings of surgical specimen of rectal cancer and endoscopic biopsy tissue from the esophagus. To the best of our knowledge, this is the first case of secondary esophageal cancer arising from rectum in Korea.

We present a case of liposarcoma related with minimal change nephrotic syndrome. A 49-year-old woman was admitted due to generalized edema and a palpable mass at epigastric area. Her laboratory data were as follows : serum creatinine 0.6mg/dl, BUN 7mg/dl, serum total protein 3.6g/dl(albumin 0.6 g/dl) serum total cholesterol 299mg/dl, 24 hour-urine protein 5.1g. A CT scan of the abdomen revealed huge adult head sized mass(15X10X15cm) consisted with mixed pattern of well enhancing solid, cystic and fat portion which is located between the liver and the stomach. A kidney biopsy showed minimal change nephropathy. At explo-laparostomy the tumor was well differentiated liposarcoma. After operation and steroid therapy, her proteinuria and hypoalbuminemia were a little improved. And then radiation therapy(daily 180 cGy, 5 fx/wk, upto 5040cGy/28 fx/42 day) was done. Complete remission of liposarcoma was followed by regression of the nephrotic syndrome. After radiation therapy, her laboratory data were serum total protein 6.7g/dl (albumin 4.3g/dl), total cholesterol 170mg/dl, 24 hour-urine protein 0.3g. She has been maintained complete remission of the nephrotic syndrome by steroid maintenance dose.

Hemangioma in the gastrointestinal tract rarely occurs especially in the stomach compared with the small and large intestine. A 45-year-old man was admitted with pneumonia. After hematemesis, the authors performed gastroscopy, which revealed active bleeding on the huge ulcer on the antrum of the stomach and multiple erosive lesions on the whole stomach. After multiple submucosal hypertonic saline injection and hemoclipping at the huge ulcerative lesion, ulcer bleeding stopped. Three days later, recurrent massive upper gastrointestinal bleeding occured at the same site of the stomach. To prevent futher recurrent bleeding, total gastrectomy with esophagojejunostomy and splenectomy was done. The histologic diagnosis of the ulcerative lesion was hemangioma of mixed type. We report this rare case with the brief literature review.

Cytomegalovirus (CMV), a member of the human herpesvirus group, causes severe disease in immunocompromised patients. In particular, CMV pneumonia can be a life-threatening disease to patients taking immunosuppressive drugs. The radiographic manifestations of CMV are variable and may consist of reticular or reticulonodular patterns, ground-glass opacities, air-space consolidations, or mixed patterns. A cavitary lesion in pneumonia associated with CMV infection is extremely rare. Herein we report on a case of CMV pneumonia which presented with a cavitary lesion and was treated successfully in a systemic lupus erythematosus patient who was taking immunosuppressive drugs.
