Apoptosis is an intrinsic and fundamental biological process that plays a critical role in the normal development of multicellular organisms and in maintaining tissue homeostasis. Some of the well known regulators of apoptosis are cytokines of the tumor necrosis factor(TNF) ligand family, such as Fas ligand(Fas L) and TNF, which induce apoptosis by activation of their corresponding receptors, Fas and TNFR-1. Recently, a new member of the TNF family known as TRAIL (TNF-related apoptosis-inducing ligand) was identified and shown to induce p53-independent apoptosis in a variety of tumor cell lines but not in normal cells, Four human receptors for TRAIL were also recently identified and designated TRAIL-R1, -R2, -R3, and -R4. The aim of this study is to examine whether TRAIL and TRAIL receptots(-R1, -R2, -R3) are expressed in uterine cervical cancer and whether it is correlated with apoptosis, TRAIL and TRAIL receptors. The subjects were 20 patients who were diagnosed with cervical cancer. Western blotting was performed in 9 cases, immunohistochemical staining for TRAIL and TRAIL receptors(-R1, -R2, -R3) and TUNEL method for detection of apoptosis in 11 cases. There were proteins for TRAIL, TRAIL-R1, -R2, and -R3 in tissues from cervical cancer. All TRAIL receptors were expressed in both normal cervical epithelium and tumor cells, and TRAIL-Rl and -R2 were more strongly expressed in tumor cells than normal epithelium(p<0.05). Apoptosis correlated with expression of TRAIL-Rl and -R2(p<0.05). This study suggests that TRAIL induces apoptosis in cervical cancer through its receptors.

BACKGROUND: Nonimmune hydrops fetalis has become an important perinatal problem since it was first described in 1943. Although recent advances in antenatal ultrasound have made it possible to detect and manage nonimmune hydrops fetalis in early pregnancy, the perinatal mortality is still high. OBJECTIVE: To obtain clinically useful data regarding antenatal diagnosis, management, and perinatal outcomes of nonimmune hydrops fetalis, and to assist clinicians offer proper antepartum counseling and obstetric management which may be able to improve prognosis. Study design: We retrospectively reviewed 33 cases of nonimmune hydrops fetalis delivered in our hospital over a 4-year period. RESULTS: The antenatal diagnosis was possible by ultrasonography in all cases. Accumulation of fluid in fetal serous cavity and generalized skin edema were observed in all cases. A probable etiology was found in 23 (69.7%) cases through ultrasonography, various laboratory studies including fetal karyotyping, and autopsies. These were cardiovascular (4), respiratory (6), chromosomal (4), skeletal (1), and others (8). Despite extensive diagnostic studies, no definite etiology was found in 10 (30.3%) cases. Excluding the ten fetuses delivered after induced abortion, eight infants were born alive and six died in the neonatal period. The mortality rate was 91.3% (21/23). CONCLUSION: Nonimmune hydrops fetalis represents a very poor perinatal outcome. It is suggested that to improve the prognosis, various antenatal and postnatal approaches to find associated etiologic factors should be performed, and intensive perinatal cares are needed.

Sinus histiocytosis with massive lymphadenopathy(SHML) is a benign, generally selflimited pseudolymphomatous disease that typically appears with cervical massive lymphaclenopathy. Extranodal involvement including skin occurs in the 28% of the cases. We report a case af SHML in 51 year-old male who had several, prominent firm masses ranging from 1-10cm in the cervical, axillary, inguinal areas and multiple, plum colored nodules and plaques in the face, trunk for about 10 years. The histopathological findings of cervical lymph node, facial nodule showed dense heavy infiltration of large histiocytes with abundant pale eosinophilic cytoplasm in the subcapsular and medullary sinuses of lymph node and dermis of skin. No atypical cells suggesting malignancy is seen in the infiltrates. The patient had been treated with combination of prednisolone and vinblasstine, but he expired 1 month later.

Ovarian cancer is the most lethal of the gynecologic cancers worldwide because most patients present with advanced stage disease at the time of diagnosis. Although multiple therapeutic modalities are employed in the management of ovarian cancer, and despite advances in chemotherapeutic and biologic agents, primary surgery followed by adjuvant chemotherapy remains the cornerstone treatment of this disease. Adequate, comprehensive surgical staging in women with early stage ovarian cancer has been shown to improve oncologic outcomes. Complete surgical cytoreduction leaving no gross residual disease is known to be the only physician-driven prognostic factor for patients with advanced disease. This review describes the rationale and surgical steps for full surgical staging for women with early ovarian cancer, and outlines the cytoreductive surgical procedures required to achieve optimal cytoreduction in patients with advanced ovarian cancer. In addition, the impact of radical surgery (as part of maximal tumor debulking) on the amount of residual tumor and on survival rates will be discussed.

Eleven patients with proved Bronchiolo-aveolar cell carcinoma were found in the chest department of thenational menical center from 1975 to 1981. The incidence of Bronchiolo-alveolar cell carcinoma is recentlyincreased as primary lung carcinoma. The result as follow. 1. The ratio of male and female was 5:6 and anincidence of 4.4% among total primary lung cancer patients. The highest incidence (3 of cases) was seen in thesixth decade, and the remaining cases were evenly distributed in the third, fourth, and fifth decades of life.Among them youngest was 29 years old and the oldest was 66 years old. 2. Clinical and radiological initialdiagnosis prior to the final diagnosis were as follows; pulmonary tuberculosis; 7 cases, pneumonia; 1 case,bronchiectasis; 1 case, and lung cancer; 2 cases. 3. Radiological examination of chest presented several pictures;most commonly, homogenous or patchy infiltrations; 6 cases, nodular or mass like densities; 2 cases, disseminatednodular or military patterns; 2 cases, and reticular pattern; 1 case. 4. Bronchogram reveald no contributablefindings except one case of complete tappering obstruction of the segmental bronchus. Therefore we arrive at theconclusion that early diagnosis will result in increased resectability and improved survival so aggressivediagnositic work-up for suspicious pulmonary infiltrate is necessary.
