Multiple factors including gastroesophageal reflux disease (GERD) were evaluated for a case-control study in Chonnam area to investigate the causative entity of COPD. Data on the multiple causative factors from hospital records and interview survey were analyzed in three groups of COPD(64 cases as case group), normal lung (83 cases as control group 1) and non-COPD lung disease (45 cases as control group 2). Smoking status, history of adulthood pulmonary infection and frequent history of URI, socioeconomic status, and GERD were significantly different between COPD group and control group 1. Drinking status, physical height of the subjects and GERD were significantly different between COPD group and control group 2. If control group 1 was used, odds ratio of GERD and COPD was 5.68(95%confidence interval, 95% CI:2.59-12.45) and 4.81 (95% CI:1.89-10.53) when adjusted by age and smoking status. If control group 2 was used. Odds ratio of GERD and COPD was 4.22 (95% CI:1.69-10.56) and 4.59 (95% CI:1.64-12.86) when adjusted by alcohol and adulthood respiratory infection status. In summary, there results suggested that GERD might play a causative role in the development of COPD.

The clinical and pathological features of a case Malignant mixed mullerian tumor of the ovary in 45 year-old female patient with a brief review of the literature are presented. She had both ovarian tumors. The masses are multilocular cystic tumor with interspersed solid component. The cystic component is filled with serous fluid. Microscopically the tumor is composed of epithelial element & intimately related mesenchymal element. The epithelial element shows the findings of adenocarcinoma of solid, glandular and papillary growth. The mesenchymal element is composed of malignant-looking stroma with cartilage formation.

Fibrous histiocytoma composed of fibroblasts and histiocytes is quite variable in histologic pattern. The biologic behavior is unpredictable by histologic ground. This tumor is well-known in subcutaneous tissue and deep soft tissue, but quite rare in central nervous system. We experienced a case of the fibrous histiocytoma involving the dura mater of spinal cord in a 26 year old female patient. In gross findings, the mass was a well demarcated, ovoid mass attached to the dura matter, and measured 2.5x1.5 cm in diameter. The cut surface was rubbery, solid, gray-white or yellow. Microscopically, the lesion consisted of polyhedral cells with round or oval nuclei and faintly eosinophilic or vaculoated cytoplasm, and multinucleated giant cells. Some giant cells were Touton-type. Composing cells were bland-looking. Mitotic figures were average 3 per 10 high power fields.

Over the past 30 years, there has been an increase in the incidence of multifetal pregna-ncies, primarily because of the introduction of ovarian stimulants for ovulation induction and assisted reproductive technology ( ART ) in infertile patients. It is well established that multifetal pregnancies are associated with an increased frequency of the maternal complications and gre-ater perinatal morbidity and mortyality. The adverse outcome of multifetal pregnancies is dire-ctly proportional to the number of fetuses, primarily as an consequence of prterm delivery. Re-duction in the number of fetuses in multifetal pregnancies has been proposed as a way to impr-ove the perinatal outcome in this situation. Therefore, selective fetal reduction ( SFR ) is sugges-ted as a therapeutic option for continuation of pregnancy with fetuses mature enough to survi-ve. In this paper, we report our infertility clinic experiences with 6 patients who carried mult- ifetal pregnancies including 1 quintuplet, 1 quadruplet, and 4 triplets. from January, 1991 to May, 1996, transabdominal SFR was accomplished by fetal intrathoracic KCl injection at 9~10 weeks of gestation. After the prcedure, 4 patients remained as twin pregnancies, and 2 patients as single pregnancy. There have been 3 sets of twin deliveries and the 2 sets of single delivery. One case was aborted. Two patients were delivered after 37 weeks of gestation, 2 patients were at 35 weeks, and 1 patient at 24 weeks. All babies have been healthy after birth in patients after 35 weeks gestation. There was no fetal anomaly related to the procedure in the 6 cases. We concluded that transabdominal SFR is a rather safe and useful procedure that may improve the outcome of multifetal pregnancies.

CD44 is a hyaluronic acid receptor that exists as a standard 90-kd form (CD44H) as well as several CD44 variants isoforms are produced through alternative splicing. Alternatively spliced variants of the CD44 molecule have been found to be associated with invasive and metastatic potential of cancer cells and poor prognosis in several types of carcinoma. The purpose of the present study is to define the expression of CD44H and CD44v6 in ovarian tumors and to investigate whether the expression of these molecules is associated with adverse prognosis. We evaluated the expression of CD44 isoforms in 58 ovarian tumors by means of immunohistochemistry, and correlated between CD44 expression and the histologic types, tumor grade, peritoneal implants, pseudomyxoma peritonei and FIGO stage. While the CD44H was commonly expressed in ovarian tumors, the CD44v6 was expressed in a minor proportion of serous tumors in comparison with frequent expression of v6 isoform in mucinous tumors. The CD44H expression was significantly higher in stage I/II than in stage III. However, there was no correlation between the expression of CD44 and the presence of peritoneal implants or pseudomyxoma peritonei. These results suggest that CD44H could play an important role in the adhesive function in the lower stage of the ovarian tumor and reduced expression in the higher stage might be related to the metastasis and widespread invasion of ovarian carcinoma cells.

This study represents the immune reaction pattern of gastric carcinoma, based on the morphologic characteristics of regional lymph nodes in the cases of stomach carcinomas. The materials were obtained from the resected specimens from 100 carcinoma patients. We chose Tsakraklides' method in classification of the structure of lymph node, which are as follows: lymphocyte predominance, germinal center predominance, unstimulated and lymphocyte depletion. The incidence was as follows: lymphocyte predominance 45, germinal center predominance 32, unstimulated 21 and lymphocyte depletion 2. In the lymph nodes of peptic ulcer, lymphocyte predominance pattern was most common. The reactivity of lymph nodes is suppressed proportionally to the severity of cancers, thus the advanced case of cancer exhibited lymphocyte depletion pattern which suggests exhaustion of immune reaction. The lymphocyte predominance pattern was frequent in superficial type and expanding type of gastric carcinoma. The cancer metastasis of lymph node in lymphocyte predominance was smaller than the other type of lymph nodes, while metastasis increased progressively higher with the orders as following: lymphocyte predominance, germinal center predominance, unstimulated and lymphocyte depletion.

Primary germ cell tumor of the testis is rare, which occupies 1 to 2% of all reported malignant male neoplasms. Combined primary germ cell tumor of the testis composed of embryonal carcinoma and seminoma is more rare tumor. The authors experienced a case of 50-year old male who presented with painless enlargement of right testicle. He has had radical orchiectomy and diagnosed by pathologically as combined germ cell tumor of testis. The testicle is measuring 180 gm in weight and 9×6×5 cm in dimension, and almostly replaced by tumor mass. Grossly the tumor is rubbery solid smooth tumor mass, with variegated cut surface with geographically outlined diffuse necrotic area. Histologically the tumor is composed of two components of tumor, which are solid growth pattern of large round to polyhedral cells with clear or granular cytoplasm and distinct cell border, and anastomosing glandular and papillary arrangement of anaplastic epithelial cells. The former corresponds to seminoma, and the latter to embryonal carcinoma. Each tumor lobule is separated by abundant fibrous stroma.
