Alterations in the expression of genes that control the cell cycle may be of critical importance in tumorigenesis and malignant transformation. The major regulatory events leading to cell proliferation occur in Gl phase of cell cycle, and the deregulated expression of Gl cyclins is related to oncogenesis. Cyclins Dl and E play important roles in the progression of cell through Gl phase of the cell cycle. Amplification and/or overexpression of the cyclin Dl gene and aberrant expression of cyclin E has been described in various forms of human cancer. However, the role of cyclins Dl and E in cervical cancer has been poorly defined. In this study, we examined the expression of cyclins Dl and E by Northern blot technique and the status of human papil- lomavirus(HPV) type 16 and 18 by polymerase chain reaction in 25 cases of cervical carcinoma to explore the relationship between cyclins Dl and E and cervical cancer. We found cyclin Dl expression showed down-regulated expression in cervical cancer but cyclin E expression was increased in cancer group. Other clinicopathological prognostic factors were not correlated with cyclins D1 and E expression. Further study based on larger numbers of cases with correlation of cyclins D1 and E status and survival data will be needed to elucidate the use of cyclin expressions as prognostic factor.

When bronchogenic carcinoma is coexisting with pulmonary tuberculosis, it is difficult to differentiate bronchogenic carcinoma from pulmonary tuberculosis radiologically. Thus, the object of this study is to define differential diagnosis of bronchogenic carcinoma by computed tomography. We analized CT scans of 27 patients with radiologic findings of pulmonary tuberculosis and mass of which twelve cases were pulmonary tuberculosis and fifteen cases were primary lung cancer. The location of parenchymal infiltration and the mass was the same in 60%(9/15) of the primary lung cancer in cases and 83%(10/12) of the pulmonary tuberculosis cases. The common location of the mass was the both upper lobes in 92%(11/12) of the pulmonary tuberculosis cases and 53%(8/15) of the primary lung cancer cases. The common locations of the mediastinal lymphadenopathy were 4R, 2R of the pulmonary tuberculosis cases and 4R, 10R of the primary lung cancer cases. In the feature of post enhanced lymph nodes, homogenous increased density was more frequent in primary lung cancer. Measurements of the maximum thickness part of the cavity wall was not a reliable indication of malignancy.

Cavernous hemangioma is the venous malformation that most frequently involves the orbit, And in orbital venography, the injection of contrast medium(conray) is made into a branch of frontal vein. The films are taken after delivery of 5 ml and immediately prior to the end of the injection. A preliminary control film is also obtained for this subtraction studies. Recently, authors experienced a case of orbital hemangioma which is caused unilateral proptosis of right eye(6 yr, old boy) and confirmed this patient as an orbital cavernous hemangioma by the technical aid of orbital venography under general anesthesia. Subtraction technique of R. orbital venograms following catheterization of one of the frontal veins revealed that 3rd segment of R. superior ophthalmic vein including 1st and 2nd segments is slightly displaced medially and superiorly of the frontal projection. They were somewhat dilated in caliber. Some dilated and tortuous vessels were filled with contrast media in the inferomedial aspect of the R. oribit from possible Srd segment of SOV. on the R. down lateral projection, there were abnormaly abundant dilated and tortuous vessels in the lateral portion of the orbit. It is fed from the R. angular vein, and CM are drained from the lesion to the dilated IOV at its posterior portion. R transfemoral arteriograms(AP, Lat) showed mild elevation of 3rd portion of the ophthalmic artery superiorly on the lateral projection, but it appeared normal caliber. The supraorbital and muscular branches as well as choroid crescent were not remarkable in this case. R. external carotid angiogram(LAT) showed within normal patterns. Angiographic diagnosis was a large venous malformation involving the lateral and posterior portions of the R. orbit, most likely cavernous hemangioma. Final diagnosis was confirmed by histopathological study of an excised hemangioma. After surgical removal the visual acuity was improved to normal without any disability of the eye.

OBJECTIVE: Our purpose was to describe the clinical progress and the maternal and fetal outcome in 16 pregnancies complicated by the HELLP(hemolysis, elevated liver enzymes, low platelet). Material: We reviewed the maternal and neonatal charts from 16 consecutive pregnancies complicated by the HELLP syndrome among 302 pregnancies complicated by preeclamsia and eclamsia managed at our hospital during the period of 4 years from June 1994 through June 1998. The HELLP syndrome was defined by previously published laboratory criteria. We assessed the time of onset, presenting symptom, laboratory finding, mode of delivery, fetal and maternal complication in each case. We also reviewed the clinical finding in detail in the case resulted in maternal death. RESULTS: In regards to the time of onset, 15 cases (93.7%) occurred at antepartum period and only 1 case (6.2%) occurred at postpartum period. Among the 15 cases occurred at antepartum period, 13 cases (81.25%) developed at 27 to 36 weeks gestation and 2 cases (12.5%) developed at near term. In regards to the presenting symptom, twelve patients (75%) complained of right upper quardrant or epigastric pain. Of 16 patients, 12 patients (75%) experienced headache and 10 patients (62.5%) complained of nausea, or vomiting and 5 patients (31.2%) had visual disturbance. The laboratory finding of all 16 cases were as follow; the mean level of platelet: 68700/mm3 (range: 48000 to 91700), the mean level of serum asparate aminotransferase: 335 IU/L (range: 62 to 135), the mean level of lactic dehydrogenase: 910 IU/L (range: 558 to 5794), and the mean level of total bilirubin: 2.6 mg/dl (range: 0.7 to 10.4). To review the mode of delivery, cesarean sections were done on 10 patients (62.5%) including 7(43.7%) emergency and 3(18.7%) elective operations. However, 6 patients (37.5%) delivered vaginally. Maternal complications were as follow; abruptio placenta in 1 case (6.2%), DIC in 2 cases (12.5%), pulmonary edema in 3 cases (18.7%), pleural effusion in 4 cases (25%), renal failure in 4 cases (25%), and 1 case of death. Fetal and neonatal outcome was assessed; 9 cases of intrauterine growth retardation (56.2%), meconium stained in 3 cases (18.7%), 2 stillbirth (12.5%), and 2 neonatal death (12.5%). CONCLUSION: HELLP syndrome is associated with serious maternal and fetal morbidity and mortality.

Dentocutaneous fistula of the face neck is an infrequent manifestation of chronic dental infection. A periapical dental abscess may be initiated by disease, trauma, or thermal or chemical injury and develops into an extensive necrosis of surrounding tissue. Diagnostic errors can result in multiple excision, biopsies, and ineffective long-term antibiotic therapy. Awarness that periapical dental abscess is the most common etilolgic factor of cutaneous sinus tracts involves the face & neck will facilitate their early diagnosis and prevent needless treatment or anxiety for the patient. From 1994 to 1998, we have performed 6 cases of dentocutaneous fistula. Among of them, three were men and the others were women, age ranged from 18 to 66-year-old, and morbidity period was from 3 weeks to 3 years, the follow-up period ranged from 5 to 18 months (mean period 11 months). In conclusion, an understanding of the pathogenesis of cutaneous fistulae arising from dental infections will lead to proper early diagnosis and treatment without unnecessary surgery.

A total of 0.3ml of 100% sulfur hexafluoride(SF6) was injected into vitreous cavity with a single shot or two 0.15ml shots, and the time dependent intraocular pressure changes were compared. Intraocular pressure was monitored at 5 minute intervals for 60 minutes after injection. Immediately after a single shot injection, remarkable intraocular pressure elevation(85mmHg, mean)was observed, which returned, however, to normal level within 15 minutes. Intraocular pressure elevation was milder when a smaller bolus of gas(0.15ml)was separately injected twice. No re-elevation of intraocular pressure was noted with either method after the initial return to normal.

100% sulfur hexafluoride(SF6) was injected into the vitreous cavity of nonvitrectomized retinal detachment patients. A total of 0.5ml of gas was injected with a single shot in 3 eyes or two 0.25ml in 3 eyes without lowering of intraocular pressure. And in 3 eyes, single shot of 0.5ml of gas was used after lowering of intraocular pressure. The changes of intraocular pressure were monitored at 5 minute intervals for 60 minutes and at one hour intervals for 8 hours after injection. Marked elevation of intraocular pressure was noted in both single shot group, but the elevation of intraocular pressure of double shot group was much smaller. But in all groups, the intraocular pressures were returned to under 30mmHg within 20 minutes and no re-elevation of intraocular pressure was noted in all cases after initial return to normal. In a case with two 0.3ml shots, the highest pressure was 49mmHg and with 0.35ml shots, the highest pressure was 78mmHg. So the effect of SF6 on intraocular pressure seemed to be negligible so long as the injection volume was limited to 0.5ml or less in single shot; and 0.6ml in double shots.

Tamoxifen is a nonsteroidal triphenylethylene delivative that has been widely used in the treatment of breast cancer. tamoxifen is indicated for the adjuvant treatment of breast cancer in women following total mastectomy or segmental mastectomy, breast irradiation and chemotherapy. tamoxifen has been shown to have significant benificial effect in the treatment of breast cancer patient as hormonal therapy. However ,there is mounting evidence that tamoxifen may affect other hormon sensitive organs, including the uterus and ovaries. An increased risk of endometrial polyps, endometrial hyperplasia and adenocarcinoma has been reported in tamoxifen treated women. We have met cases of endometrial polyp and endocervical polyp which were associated with tamoxifen use, after modified radical mastectomy for infilterating ductal carcinoma of breast . So we report these cases with the brief review of literatures.

OBJECTIVES: E-cadherin is a transmembrane protein that is one of the key players involved in cell to cell adhesion. Loss of E-cadherin expression is suggested to promote tumor invasion and distant metastasis in tumor development. Recently, it has been proposed E-cadherin function requires its linkage to the cytoskeleton through catenins. So defects in catenins may cause defective E-cadherin function and promote tumor invasion. We intend to evaluate the expression of E-cadherin and alpha-, beta-, gamma- catenin in tissues of human endometrial carcinoma to analyze the patterns of cell adhesion molecules' expression in endometrial carcinoma and to investigate the relationship between status of cell adhesion molecules and various clinicopathological factors. MATERIALS AND METHODS: The present study investigated the immunohistochemical expression of E-cadherin and alpha-, beta-, gamma- catenin in 33 paraffin embedded formalin fixed tissues of endometrial carcinomas. RESULTS: Aberrant E-cadherin, alpha-, beta-, gamma- catenin expression was observed in 33.3(11 of 33), 27.3(9 of 33), 18.2 (6 of 33), and 51.5(17 of 33) % of the specimens, respectively. Statistically significant correlation was found between aberrant expression of E-cadherin and lymph node metastasis and cell types other than endometrioid adenocarcinoma. Aberrant pattern of gamma- catenin expression also correlated with deep myometrial invasion. But alpha-, beta- catenin expression were not correlated with any clinicopathological parameters. Using Kaplan-Meier curves, abnormal expression of E-cadherin correlated closely with poor survival (p<0.05). CONCLUSION: We revealed aberrant expression of these cell adhesion molecules in part of patients with endometrial carcinoma. Aberrant expression of E-cadherin was correlated with lymph node metastasis and cell types other than endometrioid adenocarcinoma and aberrant expression of gamma-catenin was related with deep myometrial invasion.
