The effect of androgen in the development of the normal prostate and the evolution of benign prostatic hypertrophy (BPH), and prostatic adenocarcinoma has been proven. In addition to androgen, estrogen and progesterone are also thought to play a role in the pathogenesis of BPH and carcinoma. However, their exact roles are not yet known because there is no conclusive evidence. Thirty cases of prostatic adenocarcinoma and 16 cases of BPH were studied. Immunohistochemical staining for estrogen receptor (ER) and progesterone receptor (PR) in epithelial and stromal cells, respectively was performed and the results were assessed semiquantitatively based on the number of positive cells per 100 total cells. Slides were scored as negative; less than 5% of cells, 1 ; 6~15% of cells, 2 ; 16~25% of cells, and 3 ; more than 26% of cells. The relationship between ER and PR expression and the patient's age, histologic grade, and clinical stage was evaluated in prostatic adenocarcinomas. ER was negative in epithelial and in stromal cells for all prostatic adenocarcinomas and BPH cases. The PR expression in epithelial cells and in stromal cells of BPH was noted in 15 (93.8%) and 16 (100.0%) out of 16, respectively. The PR expression of carcinoma cells and stromal cells in prostatic adenocarcinoma was found in 28 (93.3%) and 23 out of 30 (76.7%), respectively. The PR immunoreactivities of stromal cells around carcinoma were 3 in 18 cases, 2 in one case, and 1 in 4 cases, but those of epithelial and stromal cells of BPH and carcinoma cells of prostatic carcinoma were similar to each other with a value of 3 in most cases. The PR expression rate of stromal cells around carcinoma was significantly correlated with the patient's age (p=0.044), but not with histologic grade and clinical stage. In summary, estrogen does not have a direct effect on the biological behavior of BPH and prostatic adenocarcinoma, but progesterone appears to play a role in the pathogenesis of BPH and prostatic adenocarcinoma. Further studies should clarify the biological role of progesterone in the human prostate.

We present a case of mucous gland adenoma arising from the main bronchus of the lower lobe of the left lung in terms of clinicopathologic, immunohistochemical, and ultrastructural aspects as well as review of related literatures. The patient, a 31-year-old female, was admitted to Catholic University Medical College Hospital with complaints of coughing and purulent sputum for about seven years. The chest CT showed a severely calcified tumor in the left lower lobe of the lung. Grossly, the calcified tumor arising from the main bronchus protruded into the lumen and showed bronchiectasis of the lower lobe and atelectasis of the upper lobe of the lung. The tumor was pale brown-gray and sharply circumscribed and showed some small cystic spaces filled with mucoid material. Microscopically, most of the tumor showed dystrophic calcification. The growth pattern of the tumor is composed of cysts, tubules, and glands lined by cytologically bland columnar, cuboidal, or flattened mucus secreting cells. Electron micrograph of tumor cells showed some round or oval mucous granules measuring 0.5-1.8 micrometer.

A case of a 58-year-old man with malignant fibrous histiocytoma (MFH) of the right ventricle is reported light and electron microscopically. This is the first case of MFH of the heart in the Korean literature. A tendency for malignant fibrous histiocytoma of the heart to occur in the left atrium of young women is suggested; this sarcoma's usual location is in the soft tissue of elderly men. The tumor consisted of spindle cells arranged in a focal storiform patterns, clusters or sheets of histocyte-like cells, benign and malignant giant cells, inflammatory cells, scattered mitotic figures and anaplasia of stromal cells. In ultrastructure the constituent of cells of the tumor are primitive mesenchymal cells, histiocytoid cells and fibroblast like cells including giant cells.

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.

In Korea, the proportion of B-cell and T-cell lymphomas has not yet been clearly estimated. In the present study, we analysed clinicopathologic and immunophenotypic findings in 60 cases of non-Hodgkin's lymphomas(NHL) and in 17 cases of polymorphic reticulosis. Immunohistochemical studies for monoclonal antibodies, such as MB2, UCHL-1, Kappa/Lambda light chains, and IgG/IgM/IgD heavy chains were performed on formaldehyde-fixed paraffin embedded tissue sections. Among 60 cases of NHL, 28 cases(46.7%) expressed B-cell markers, 29 cases(48.3%) T-cell markers, and 3 cases(5.0%) lacked detectable markers, whereas 16 of 17 cases(94.2%) of polymorphic reticulosis reacted with T-cell markers. The mean survival of the 16 cases of T-cell lymphoma group was shorter than that of the lymphoma group positive for B-cell markers.

Heat shock protein of 72 kDa (HSP70) has a role in the functional modulation of sex steroid hormone receptors and in p53-associated oncogenesis and inhibits apoptosis associated with bcl-2. However, the exact role of HSP70 in the development of endometrial adenocarcinoma has not been well established. The aim of this study is to evaluate the role of HSP70 in relation with ER, PR, p53 and bcl-2 expressions and apoptosis in benign and malignant endometrial lesions. Immunohistochemical studies for HSP70, ER, PR, p53, bcl-2 and TUNEL method for apoptosis were performed in 30 cases of adenocarcinoma and 30 cases of benign endometrial lesions consisted of each 10 cases of disordered proliferative endometrium (DP), simple or complex hyperplasia (HP), and atypical hyperplasia (AH). There were no significant differences of HSP70 and bcl-2 expression rates and apoptotic index (AI) between DP, HP, AH, and adenocarcinoma. p53 expression rate in adenocarcinoma was 36.7%, but no p53 expression was identified in DP, HP and AH (p<0.05). In adenocarcinoma, HSP70 expression rate was higher in ER and PR negative adenocarcinoma (p<0.05), and p53 expression rate was higher in nonendometrioid type and FIGO grade II and III (p<0.05), but no significant difference of bcl-2 expression rate according to the histological type and FIGO grade. AI was higher in nonendometrioid type (p<0.05). There was no correlation between HSP70, p53 and bcl-2 expressions, and no significant difference of AI according to HSP70, ER, PR, p53, and bcl-2 expressions. In conclusion, higher HSP70 expression rate in poorly differentiated and ER and PR negative adenocarcinoma suggests that HSP70 inhibits ER and PR expression and may be involved in the development of poorly differentiated endometrial adenocarcinoma.

A clinical observation was made on 10 cases of modified Denis-Browne urethroplasty experienced at Department of Urology, Jeonbug National University, from January 1978 to July 1980 and the following results were obtained: 1. The age was distributed from 2 years to 44 years and most of cases was found in the age group which was less than 7 years. 2. Among 10 cases of modified Denis-Browne urethroplasty, 4 cases were penile hypospadias, 4 cases were penoscrotal hypospadias and 2 cases were perineal hypospadias. 2 cases of penile hypospadias were not combined chordee. 3. Cryptorchism and meatal stenosis were the most common associated anomalies. 4. Interval from chordectomy to modified Denis-Browne urethroplasty took 6 months to 1 year in 6 cases (75%), with the average of 10 months 5. We performed trocar cystostomy as urinary diversion in all cases. 6. 3-layer longitudinal monofilament subcuticular suture was used in all cases. 7. Among 10 cases, complications developed in 2 cases (20%), one case was urethral fistula, the other was urethral stricture 8. Success rate of modified Denis-Browne urethroplasty in our cases was 80%.

Amniotic fluid embolism (AFE) is a rare but potentially fatal complication that occurs acutely during pregnancy or within 12 h of delivery. The management of AFE focuses initially on supportive measures for cardiopulmonary stabilization. Extracorporeal membrane oxygenation should be considered in patients who are unresponsive to medical treatment in order to prevent additional hypoxia and subsequent organ failure. We present a 41-year-old woman with clinical AFE who developed acute respiratory distress syndrome and was treated successfully with extracorporeal membrane oxygenation.
