Recently, the bcl-2 and p53 protein have been recognized as important factors that is contributed to programmed cell death. The objective of this study was to evaluate the prognostic significance of bcl-2 and p53 protein expression in uterine cervical carcinoma. The expression of bcl-2 and p53 in 59 cases of uterine cervical carcinoma (stage IB to IIB) were surgically treated from January 1993 to June 1994. The expression of bcl-2 and p53 was examined by immunohistochemical method using formalin fixed paraffin embedded tissue specimens. The 48 cases were squamous cell carcinoma and 11 cases were adenocarcinoma. The results were as follows: 1. The expression rate of bcl-2 protein was 28.8%(17/59) and there was no significant correlaltion between the expression of bcl-2 protein and the clinicopathologic parameters (histologic type, grade, FIGO stage, cervical invasion depth, lymph node metastasis, parametrial invasion, tumor size, neoadjuvant chemotherapy response, recurrence, survival). 2. The expression rate of p53 protein was 32.2%(19/59) and there was no significant correlation between expression of p53 protein and the clinicopathologic parameters. 3. There was significant correlation between and expression of bcl-2 and p53 protein (P 0.05). In conclusion, bcl-2 and p53 protein are thought to be possible factors in the carcinogenesis of uterine cervical carcinoma and correlate with progression of it. But further study will be required to clarify the role of bcl-2 and p53 in carcinogenesis of the uterine cervix.

OBJECTIVE: The purpose of this study was to review the clinicopathologic features, recurrent rate, survival rate and controversable issues in the treatment of the ovarian malignant germ cell tumors. PATIENTS AND METHODS: From August, 1991 to November, 1998 thirty-one patients with malignant germ cell tumors of the ovary treated in the department of obstetrics and gynecology, Kosin University Medical college, were eligible and assessable. Demographic characteristics, symptoms, signs, stage, tumor grade, mode of therapy and results of follow up were reviewed retrospectively. RESULTS: The patients with malignant germ cell tumor constituted 6.37% of all ovarian malignancies during this period. Histologic subtypes were 8 dysgerminoma(25.8%), 7 endodermal sinus tumor(22.6%), 10 immature teratoma(32.3%), 3 mixed germ cell tumor(9.7%), 3 choriocarcinoma(9.7%). The age of the patients ranged from 10 to 40 years (mean +/-S.D.; 24.26 +/- 7.51). The most common symptom was abdominal pain(38.7%). Most had stageI(18 cases, 58.0%) or stageIII(5 cases, 16.2%) diseases. All patients underwent surgery as the initial treatment, and nine patients received more than one operation. Postoperative adjuvant chemotherapeutic regimens were VAC, VBP, EP, BEP, EMA, and EMA CO. The mean follow up duration was 26.0(+/- S.D.; +/- 20.3) months. The 2-year and 5-year survival rate were 91.97%(+/- S.E.; +/- 0.05) and 86.86%(+/- S.E.; +/- 0.07).

PURPOSE: This study was conducted to investigate case-fatality rates and survival rates, prognostic factors of prevalent five cancers(stomach, lung, liver, cervix, colon) in a university hospital located in Taejon City. METHODS: 2,158 cancer patients who have admitted the hospital from Jan. 1, 1991 to Dec. 31, 1998 were analysed. The higher ratio of outbreak and growing were selected among the investigated cancer data for over 100 of subjects in Korean cancer patient was examined into two method. The one is medical record and the other is affirm a government office for existence or not. RESULTS: The lung cancer was discovered for the highest fatality rate. The crude 5-year survival rate of all cancer patients was 43.9% and that in male was higher than that in female. The 5-year survival rate of stomach cancer patients were 49.7%, that treated with combined(operation and chemotherapy) were 66.2%, that with metastasis to lymph node were 48.1%, and distant metastasis were 31.9%. Lung cancer patients were 25.9%, that treated with operation were 42.7%, and that with metastasis to lymph node were 29.3%. Hepatoma patients were 25.5%, that treated with operation were 37.8%. Uterine cervix cancer patients were 74.8%, that treated with operation were 95.0%, that with metastasis to lymph node were 83.3%, and distant metastasis 74.8%. Colon cancer patients were 41.8%, that treated with operation were 50.2%, that with metastasis to lymph node were 33.4%. Prognostic factors affecting survival rate among stomach cancer patients were age, operation, operation with cancer chemotherpy, and metastais to lymph node and distant matastasis. Prognostic factors of uterine cervix cancer was age, and that of colon cancer were operation with radiotherapy, metatasis to lymph node and distant metastasis. CONCLUSION: case-fatality rate in male were higher than that in female, and increased with age. The cancer survival rate of female is high, the high in over 40 years group, and operation is exposed in the highest survival rate, also significant difference in metastasis level.

Purpose:
To evaluate and compare the degree of visualization of the vitreous and internal limiting membrane (ILM) during pars plana vitrectomy (PPV) using preservative-free triamcinolone acetonide (PF-TA) or triamcinolone acetonide suspension (TAS).
Methods:
We retrospectively analyzed the medical records of 61 eyes of 61 patients who underwent 25-gauge PPV and ILM peeling for various macular diseases. We assigned the patients to PF-TA and TAS groups, i.e., according to the type of triamcinolone acetonide used. The degree of visualization of the vitreous and ILM was classified into four different categories. The number of dye injections during PPV, need for indocyanine green (ICG), time elapsed before ILM peeling, and intraocular pressure (IOP) before surgery, 1 day and 1 month after surgery were determined.
Results:
The degree of visualization of the vitreous and ILM was significantly better in the PF-TA group compared with the TAS group. Although the number of dye injections during PPV was not different between the PF-TA and TAS groups (2.56 ± 0.07 and 2.37 ± 1.08, respectively, p = 0.06), the need for ICG was significantly different (6 and 22 eyes, respectively, p < 0.01). The time elapsed before ILM peeling was 185.68 ± 130.02 s in the PF-TA group and 411.15 ± 267.38 s in the TAS group (p < 0.01). The IOP was not different before or 1 day after surgery between the PF-TA and TAS groups, but was significantly different 1 month after surgery (12.88 ± 3.10 and 14.41 ± 2.91 mmHg, respectively, p = 0.03).
Conclusions
Visualization of the vitreous and ILM was better when using PF-TA compared to TAS. PF-TA-assisted PPV could reduce the usage of ICG and was associated with a reduced latency to ILM peeling. Because this was in turn associated with a lower IOP at postoperative 1 month, PF-TA was safer and more effective than TAS.

OBJECTIVE: Mycoplasmas have been implicated in many diseases including cervicitis, urethritis, salpingitis, endometritis... and functioning as cofactors catalyzing the HIV disease state. The oncogenic potentiality of mycoplasma was only recently realized when they were shown causing chromosomal changes and in vitro cell transformations through gradual progressive chromsomal loss and translocation. Few study has been reported the prevalence of mycoplasma infection in human cancers and suggested that there was a connection between these organisms and human cancers. The objective of this study was to determine the relationship between Ureaplasma urealyticum infection and cervical cancer. METHODS: The detection frequency of Ureaplasma urealyticum in 52 invasive cervical cancer tissues and 17 normal cervical tissues was studied using PCR. RESULTS: U. urealyticum DNA was detected in 8 out of 52(15.4%) invasive cervical cancer tissues and 1 out of 17(5.9%) normal cervical tissues. No statistic significance was observed between the detection frequency of Ureaplasma urealyticum and clinicopathologic parameters. The prevalence of Ureaplasma urealyticum in invasive cervical tissues was 15.4% and this rate was higher than 5.9% in normal cervical tissues but there was no statistic significance. CONCLUSIONS: With respect to clinicopathologic parameters of cervical cancer, there was no significant relation between U. urealyticum infection and cervical cancer. There is, however, few study and case on cervical cancer internally and externally. It is considered that more studies on the subject with much cases should be made.

OBJECTIVE: The human MAGE 3 gene encodes tumor specific antigens that are recognized by autologue cytotoxic T lymphocytes (CTL). The MAGE 3 gene is expressed not only in melanoma but in the other malignant tumors as well. There is, however, little information on the expression of the gene in uterine cervical carcinomas. The author thus studied the expression of the MAGE 3 gene products in uterine cervical carcinoma and discuss the possibility of specific immunologic diagnosis using MAGE 3 gene products. METHODS: The expression of MAGE 3 gene product in 17 normal tissues of the cervix, 32 cervical intraepithelial neoplasia (8 CIN I, 10 CIN II, 14 CIS), and 43 invasive cervical carcinomas was studied by immunohistochemistry using anti-MAGE 3 mAb 57B in paraffin sections RESULTS: No expression of MAGE 3 gene product was detected in normal cervical tissues and in cervical intraepithelial neoplasias. The expression of MAGE 3 gene product was detected in 30.2% (13/43) of invasive cervical carcinomas. The MAGE 3 gene product was stained as a cytoplasmic protein in cancer cells. No statistically significant differences were observed between MAGE 3 gene product expression status and clinicopathologic parameters. CONCLUSIONS: The MAGE 3 gene products was expressed in invasive cervical carcinoma tissues.

OBJECTIVE: Schizophrenia is known to have high genetic influences. Recently, the main focus of etiologic study in schizophrenia has been concentrated on molecular genetic approach including polymorphism analysis. This study was designed to investigate the relationship between schizophrenia and immunologic influences by analyzing polymorphism of TNFB that is involved in interaction between immunologic system and CNS. METHOD: 146 schizophrenic patients diagnosed by DSM-IV criteria were included and data of 206 normal population from the Catholic Hemopoietic Stem Cell Information Bank(Seoul, Korea) were used as a control group in this study. DNA was extracted from whole blood, thereafter amplified by polymerase chain reaction, and digested by NcoI. We obtained and assessd RFLP of two alleles, TNFB1 which has a NcoI restriction site generating 555bp and 185bp fragments, and TNFB2 which lacks the NcoI restriction site. All data were analyzed by K 2 test. RESULTS: There were no significant differences in frequency of TNFB1/1, TNFB1/2, and TNFB2/2 between the schizophrenic patient and the control group. Alleric frequencies of TNFB1 and TNFB2 were significantly different between schizophrenic patient and control group. CONCLULSION: We found the possible association between alleles of TNFB and schizophrenia in this study. To clarify the influences of TNFB on schizophrenia, further systematic studies should be conducted.

The tethered cord syndrome is a clinical entity manifested by progressive motor and sensory changes in the legs, incontinence, back or leg pain, and scoliosis in young children. Based on remarkable neurological improvement after release of cord tension by sectioning the filum, it might be concluded that the neurological deficit was effected by cord tethering. The main objective of this experiments was to elucidate the pathophysiology involved in the tethered cord by observing the effect of tethered cord on regional spinal cord blood flow(rSCBF) and somatosensory evoked potentials(SEPs) and define a threshold relationship between SEP and rSCBF. Thirty adult cats, weighing 2.7 to 4.2kg were used in this study. The cats were divided into three groups as follows: Control group=non-tethered(10 cats), 5g-traction group=cord traction with 5g weight(10 cats). 10g-traction group=cord traction with 10g weight(10 cats). The rSCBF and SEP measurements were performed immediately after cord traction in each animal, at 30, 60, 90, 120 minutes and the final rSCBF at 3 hours by the hydrogen clearance technique. The results obtained were as follows: 1. Traction and resulted in a reduction of flow to 30%(6.0+/-1.4ml/100g/min) of normal control spinal cord flow(18.2+/-1.6ml/100g/min) at adjacent area of traction(L1) in 5g-traction group and 18%(3.5+/-0.7ml/100g/min) of normal control flow in 10g-traction group during the cord traction for 3 hours. 2. From 30 minutes to 3 hours following the cord traction, there was a tendency toward marked reduction of the blood flow at the adjacent area(L1, T10) in 10-traction group. 3. The rostral area of spinal cord away from traction was less influenced in a reduction of blood flow following the cord traction. 4. A close correlation was found between spinal evoked potentials and flow suggesting a threshold relationship. 1) The SEP was present shortly after traction though marked by altered in shape and suppressed. 2) The SEP responses progressively decreased in latency at the adjacent distal area of the cord during traction, however less changed in shape at the rostral area of the cord. 3) The SEP suppressed in shape if the blood flow in spinal cord was below 14ml/100g/min. 4) The neuronal dysfunction caused by tethered cord could be due to impairment of blood flow. It is assumed that prolonged neuronal dysfunction may lead to structural damage of the neuron.
