In 1988, the International Federatioa of Gynecology and Obstetrics(FIGO) Cancer Committee changed the staging of endometrial carcinoma from a clinical one to a surgicopathologic one. The emphasis in the new FIGO system was changed to the pathologic findings in the uterus, cervix, adnexae, and pelvic and/or periaortic nodes, and peritoneal cytologic findings. The major changes in this staging system were the use of the depth of myometrial invasion and the identification of tumor cells in peritoneal cytologic examination and of invasion in the retroperitoneal lymph nodes, Preoperative endocervical curettage was no longer necessary. This is a reflection of the increase in the primary surgical approach to the treatment of this disease and has allowed the identification of a number of prognostic factors on which postoperative therapy can be based. This retrospective study was based on a clinical review of 45 patients with endometrial carcinoma from Jan, 1985 through Jan, 1996 who underwent primary surgical evaluation at the Department of Obstetrics and Gynecology, Kyungpook National University Medical College. The results obtained are as follows; l. Age distribution of endometrial cancer was concentrated on the age group of 50-59(55.6%) and mean age was 53.9 years. 2. The mean parity and mean BMI(Body Mass Index) of endometrial cancer were 3.8 and 25.0(cm/kg2). 3. The Menstrual status at the time of development of endometrial cancer showed that 24 cases (53.3%) were postmenopausal, 11 cases (24.4%) were premenopausal and 10 cases(22.2%) were menstruating. 4. According to the clinical stage adopted by FIGO classification, stage I was found in 71.1%, stage II in 17.8%, stage III in 2,2%, stage IV in 0.0%. 5. Surgical restaging according to new FIGO classification(1988), stage IA was found in 4.4%, stage IB in 37.8%, stage IC in 28.9%, stage IIA in 0.0%, stage IIB in 0.0%, stage IIIA in 6.7%, stage IIIB in 4.4%, stage IIIC in 8.9%, stage IVA in 2.2% and IVB in 6.7%. 6. According to WHO histopathological classification, the percentage of the adenocarcinoma was 86.7%, adenoacanthoma 4.4%, papillary serous adenocarcinoma 2.2%, and adenosquamous cell carcinoma 6.7%. 7, The relationship between histologic grade and depth of invasion was somewhat correlated but no staistical significance. 8. There was no correlation between BMI(Body Mass Index) and histologic grade, depth of invasion. 9. Surgery upstaged 15.6% of clinical stage I patients and 62,5% of clinical stage II, but 37.5% of clinical stage II patients was downstaged. 10. All cases were primarily treated by surgery. Regarding the types of operation, total abdominal hysterectomy with bilateral salpingoophorectomy was performed in 44.4%, radical hysterectomy with both pelvic lymphadnectomy in 42.2%, total abdominal hysterectomy with bilateral salpingoophorectomy with selective pelvic lymph node dissection in 8.9%, and laparoscopic assisted vaginal hysterectomy in 2.2%. 11. The mean follow up interval was 38.6 months. 28 cases were followed up and 10 cases of surgical stage I revealed over 5 year salvage. 5-year survivals for surgical stage IA, IB, IC, III, and IV were 100, 100, 92.3, 88.9, and 100%, respectively.

Malignant germ cell tumors occur in children and young women in reproductive age, of all the germ cell malignancies, only pure dysgerminomas had a high cure rate prior to 1970. This was due to the exquisite radiosensitivity of these tumors. Multiple-agent chemotherapy has dramatically improved the pmgnosis of patients with malignant ovarian germ cell tumors. Clinicopathological analysis was performed on 21 cases of malignant germ cell tumors of the ovary, 9 cases at the department of Obstetrics & Gynecology, Kyung-pook National University Hospital, 4 cases, at the department of Obstetrics and Gynecology, Dong-guk University Kyungju Hospital and 8 cases, at the department of Obstetrics and Gynecology, Dae-gu Fatima Hospital during the period 10 years from July. 19S8 to June. 1997 The results were summarized as follows: 1. The mean age of the patients was 21.8 years old, ranging from 10 to 61 years old. 2. Main initial symptoms were abdominal distension(33.3%), abdominal mass palpation(33.3%), abdominal pain(28.6%), amenorrhea(4.8%) in order. 3. Histologically, the tumors were classified as immature teratoma(57.1%), dysgerminoma(19%), mixed germ cell tumor(9.5%), endodermal sinus tumor(9.5%), embryonal cell carcinoma(4.8%). 4, According to FIGO classification Stage I was the most prevalent(57.1%) at the time of diagnosis while Stage III was forward in 48.6%, Stage II in 9.5%, and no Stage IV, 5. The 5-year survival rate was 80.4% and three patients have died of malignancy and the other 18 patients live without disease from 11 to 102 months, with a median follow-up of 34.2 months. 6. Prognostic factors of malignant germ cell tumors in this study were the clinical stage, the presence of ascites and the residual tumor mass.

Microinvasive carcinoma of the uterine cervix(Stage Ia) is the earliest stage of squamous carcinoma. The transition from preinvasive to invasive disease is a crucial juncture in the development of cervical cancer. The clinical experience that microinvasive lesions carry a better prognosis justifies a separate diagnostic category. To investigate the clinical and pathological aspects of microinvasive cervical carcinoma, a retrospective study was made on 84 cases, histologically reconfirmed surgical specimens, which had been treated during the period from January, 1985 to December, 1996 at Department of Obstetrics and Gynecology, Kyung-pook National University Hospital. We defined microinvasive carcinoma as stromal invasion not exceeding a depth of Smm from the base of the epithelium presented by FIGO in 1985. The results obtained were as follows; 1. Mean age of 84 patients was 46.9 year old, all were parous women but not 1 patients. 60 cases(71.4%) belonged to stage Ial and 24 cases(28,6%) to stage Ia2. 2. Chief complaints were postcoital spotting and leukorrhea. 3, The corresponding rate of Pap. smear to histologic diagnosis was approximately 29.8%. However correponding rate within one histologic grade was about 33,3%. 4. According to the colposcopic examination, 26.4% of cases revealed suspected abnormal findings suggesting invasive lesion. 5. As to the reports of punch biopsy, 55.1% of cases showed microinvasive and/or invasive lesion. With additional diagnostic conization of cervix, the preoperative diagnosis were correct in 72%. 6. Operation performed were simple hysterectomy, extrafascial hysterectomy or modified radical hysterectomy with both pelvic LN dissection, Simple hysterectomy was most commonly performed. 7. Post-treatment complications were developed in 73.9% of patients who were done with modified radical hysterectomy with both pelvic LN dissection and bladder dysfunction was developed in 50% of the patients.

The authors have experienced two cases of general anesthesia for repair of congenital diaphragmatic hernia. Both patients were female (1 year 5 months and 8 months of age) and had left sided Bochdalek hernia. Anesthesia was maintained with halothane-oxygen using nonrebreathing system with Ruben valve, and the patients tolerated the whole procedure very well. The importance of maintaining adequate ventilation with high concentrations of oxygen and avoiding abdominal distension has been stressed.

Hepatocellular carcinoma(HCC) is malignant tumor frequently occurring in Koreans. There have been few reports regarding the cytologic findings of fine needle aspiration(FNA) of HCC. Most have suggested a diagnostic problem in the cytology distinguishing HCC from some benign hepatic lesion-for example, a regeneration nodule in cirrhosis and liver cell adenoma. In spite of its high frequency in Korea, no cytologic study has been reported, concerning the FNA of HCC. In an attempt to achieve cytologic criteria for the diagnosis of HCC, the authors studied retrospectively cytopathologic findings of 247 cases of HCC. These cases were confirmed either by histologic examination including lobectomy, biopsy, or cell block material, or, when tissue diagnosis was unavailable, by a high serum alpha-fetoprotein level(over 400 I. U.). All aspiration smears were stained by the Papainicolaou method. In each case, the smears were analyzed for cell patterns and various cytomorphology of the tumor cells. The smear background was assessed for the presence of tumor cell necrosis and inflammatory components and compared to that of metastatic carcinomas. The cell patterns were classified as trabecular, acinar, dispersed, and irregular. The cytologic parameters analyzed included the degree of nuclear atypia and the presence of mitoses, intranuclear cytoplasmic inclusions, nucleolar prominency, endothelial lining, multinucleated giant cells, eosinophilc, globules bile and Mallory body. Most of the FNA of HCC showed markedly cellular smears. The tumor cells were most frequently arranged in a trabecular pattern(80.3%). The irregular(12.6%), the acinar(5.5%), and the dispersed patterns(1.7%) followed in decreasing frequency. Individual hepatoma cells were larger than normal liver cells. However, they had morphologic features characteristic of the hepatic cells : the cells were round or polygonal, their cytoplasm was abundant and granular with eosinophilic or amphophilic stainability, and their nuclei were round to oval, located centrally, and tended to have prominent nucleoli. Anaplasia and pleomorphism of tumor cells were generally mild to moderate. These findings existed even in very well differentiated cases. Mitotic figures were present in about 85% of the cases. Prominent nucleoli were observed only in about half the cases. The frequency of other cytologic features was as follows : intranuclear cytoplasmic inclusion in 86.8% ; endothelial lining in 56.1% ; bile in 19.8% ; and giant cells in 60.1%. Clear cells were often present in 11.7%, Most aspiration smears of HCC displayed clean background without necrosis or inflammatory material in contrast to the dirty, necrotic background of metastatic cancers and cholangiocarcinomas. Based on the above mentioned features, it is suqqested that the cytologic critieria most important for the diagnosis of HCC include a markedly cellular smear, trabecular pattern. hepatocytoid appearance of tumor cells, endothelial lining, the presence of bile, giant cells, intranuclear cytoplasmic inclusions, and prominent nucleoli, Among these, trabecular pattern, endothelial lining, giant cells and clean smear background are points to be considered in differentiating HCC from metastatic and cholangiocellular carcinoma.

During a 36-month period, clinical outcome in 170 patients with traumatic intracerebral hematoma(TICH) was analysed. These patients represented 5.1% of 3328 consecutive patients with head injuries admitted to the Soonchunhyang University Chunan Hospital. The overall mortality was 33.5%. A significant number of patients(52.6%), who were not comators at the time of admission(GCS<8), were dead. The factors affecting prognosis were as follows: 1) Glasgow Coma Scale(GCS) on admission(p>0.005) ; 2) the presence of associated lesions(p>0.01) ; 3) time delay of two hours or more from admission to operation(p>0.05) ; 4) actual midline shift of 4.5mm or above on initial CT scan(p>0.005) ; 5) obliteration of suprasellar cistern(p>0.005) ; 6) the presence of delayed traumatic intracerebral hematoma(DTICH) in non-surgical patients with GCS score of 8 or above(p>0.01). Age and location of hematoma did not affect outcome, but the patients with multiple located hematoma showed higher mortality than the others. Time delay in the treatment of TICH and DTICH contribute significantly to poor outocme. Rapidly progressive DTICH within 48 hours after trauma is high in mortality. Follow-up CT scan might as well be performed till 48 hours after injury and 8 hours after initial operation, even though neurological status did not alter for the worse.

Computerized tomography(CT) have been available for diagnosis and localization of intracerebral hematoma. CT-guided stereotactic evacuation of spontaneous intracerebral hematoma was performed in 34 cases; 25 basal ganglionic hematomas with or without ventricular perforation, 4 subcortical, 3 thalamic, 1 cerebellar and 1 pontine. The biplane CT image were taken to determine the coordinates of the target point, which was the center of the hematoma. The liquefied or solid portion of the hematoma was aspirated through a burr-hole under local anesthesia. And a silastic tube(3.3mm in outer diameter and 2.0mm in inner diameter) was then inserted into the center of the hematoma. Immediately after the first trial of hematoma aspiration, urokinase(6000IU/5ml saline) was administered through the tube. Subsequently, aspiration and infusion of urokinase were repeated every 6 or 12 hours until the hematoma was almost completely evacuated. The follow-up results indicate that this procedure was more superior over the conventional craniotomy. This CT-guided stereotactic operation has the following advantages; 1) the procedure is simple and safe; 2) the procedure can be performed under local anesthesia; and 3) the hematoma can be completely drained with the aid of urokinase. This procedure can be used as a standard treatment for intracerebral hematoma. We have draw the following conclusions; As a result of the above study 1) Stereotactic surgery is more effective in the patients with neurologic grade 3 than conservative one (p<0.05). 2) To use urokinase or perform the early surgery within 24 hours did not seem to be the cause of rebleeding. 3) In the case of pons or cerebellar hemorrhage, stereotactic surgery had definite benefit in the recovery of consciousness even if recovery of motor function was dismal. 4) In patients with spontaneuous ICH, the favorable prognostic indicatiors were as follows: the size of hematoma less thas 50ml, no signs of transtentorial herniation and patient's age under 60.

BACKGROUND AND OBJECTIVE: Eosinophil is a major inflammatory cell in allergic diseases and parasitic infestations. Various cytokines such as GM-CSF, IL-3 and IL-5 are known to activate eosinophils and prolong their survival. Among them, IL-5 is the most potent stimulator of eosinophil survival. Recently, it was reported that increased expression of Bcl-2 is related to prolonged survival of IL-5 stimulated eosinophil. Theophylline is a useful drug in bronchial asthma, due not only to bronchial dilation but also to its anti-inflammatory effects. It has been suggested that anti inflammatory action of theophylline derives from the reduction of inflammatory cells in the airways which is mechated by stimulat on of apoptosis of inflammatory cells. In this study, we investigated, by measuring Bcl-2 expression of IL-5 stimulated eosinophil, the effect of theophylline on apoptosis as one of the anti-inflammatory action. MATERIAL AND METHOD: Peripheral eosinophils were isolated from atopic patients by using Perco- 11 discontinuous gradient and purified by negative selection technique using MACS. Eosinophil viability and apoptosis were measured by FACscan. Expression of Bcl-2 protein in eosinophils was detected by Western blot and ELISA. RESULTS: IL-5 increased the percentage of viable eosinophils and reduced the apoptosis of eosinophils in a dose dependent manner. The increased survival of IL-5 stimulated eosinophils was reduced by theophylline via activation of apoptosis. Bcl-2 was increased when eosinophils were cultured with IL-5 only, but when theophylline was cocultured, reduced Bcl-2 was seen with Western blot and ELISA. CONCLUSION: IL-5 increases the survival of eosinophil through the enhanced expression of Bcl- 2. Theophylline has counter action against IL-5 via inhibition of Bcl-2 induced by IL-5. Inhibiting the prolongation of eosinophil survival caused by IL-5 might be one possible mechanism of antiinflammatory effects of theophylline.

BACKGROUND: Interleukin-5 (IL-5), IL-3, and GM-CSF are known to prolong the survival of eosinophils, and IL-5 has the most potent effect on eosinophil survivaL It is also known that divergent signals induce apoptosis in different cells. But, There have been few reports on about the intracellular signals that trigger the effectors of apoptosis. Cyclic AMP (cAMP) can modulate apoptosis in many cells. But, the role of intracellular cAMP in the IL-5 induced eosinophil survival is still not completely understood. OBJECTIVES: This study was aimed to elucidate the role of intracellular cAMP in IL-5 induced eosinophil survival. MATERIAL AND METHOD: Eosinophils were isolated from peripheral blood of atopic patients. Eosinophil viability was measured by means of propidium iodine (PI) method and the number of viable cells was counted by FAC scan (Becton Dickinson, USA). Cells were cultured with or without IL-5, and also with various cAMP-elevating agents (dibutyryl cAMP, 8-bromo-cAMP, N6- benzoyl cAMP). The concentrations of cAMP were measured by cAMP enzyme immunoassay system(BiotrakTM, Amersham). Finally cAMP dependent protein kinase A inhibitor (H8) was added to eosinophils to examine the effect of decreased intracellular cAMP activity on the viability of eosinophils stimulated with IL-5. RESULTS: The percentage of viable eosinophils was reduced rapidly from 92.1+/-1.8% to 8.23+/- 3.41% without IL-5 (p<0.05; n=ll, 4-day incubation). Upon addition of IL-5, it was increased to 33.02+7.8% (p<0.05; n=ll). In the absence of IL-5, the addition of cAMP-elevating agent increased eosinophil viability in a dose-dependent manner. Upon addition of H8 (24 uM), the eosinophil viability increased by IL-5 (52.5+/-6.4%) was significantly reduced to 27.2+/-5.4% (p<0.05;n=7). Compared with tissue culture media (TCM) only, IL-5 produced persistent elevation of intracellular cAMP of eosinophils in a time and dose dependent manner.
