Abstract
We found that cells of Vibrio parahaemolyticus possess an energy-dependent efflux system for norfloxacin. We cloned a gene for a putative norfloxacin efflux protein from the chromosomal DNA of V. parahaemolyticus by using an Escherichia coli mutant lacking the major multidrug efflux system AcrAB as the host and sequenced the gene (norM). Cells of E. coli transformed with a plasmid carrying the norM gene showed elevated energy-dependent efflux of norfloxacin. The transformants showed elevated resistance not only to norfloxacin and ciprofloxacin but also to the structurally unrelated compounds ethidium, kanamycin, and streptomycin. These results suggest that this is a multidrug efflux system. The hydropathy pattern of the deduced amino acid sequence of NorM suggested the presence of 12 transmembrane domains. The deduced primary structure of NorM showed 57% identity and 88% similarity with that of a hypothetical E. coli membrane protein, YdhE. No reported drug efflux protein in the sequence databases showed significant sequence similarity with NorM. Thus, NorM seems to be a novel type of multidrug efflux protein. We cloned the ydhE gene from E. coli. Cells of E. coli transformed with the cloned ydhE gene showed elevated resistance to norfloxacin, ciprofloxacin, acriflavine, and tetraphenylphosphonium ion, but not to ethidium, when MICs were measured. Thus, it seems that NorM and YdhE differ somehow in substrate specificity.

Abstract
We detected chloramphenicol/H+ antiport activity in membrane vesicles of Escherichia coli and cloned a gene for the antiporter from chromosomal DNA of E. coli. Introduction of the gene into E. coli cells conferred resistance to chloramphenicol and ethidium. A slight increase in resistance to acridine orange was also observed. Elevated chloramphenicol efflux and ethidium efflux were observed in cells harboring a plasmid carrying the gene. Addition of chloramphenicol to the assay mixture reduced the efflux of ethidium. Elevated chloramphenicol/H+ antiport activity was observed in membrane vesicles prepared from cells harboring the plasmid. The pH optimum for the activity was 6.5. We sequenced the gene and deduced the amino acid sequence of its product. A sequence homology search revealed that it was same as that of Cmr (or MdfA). Thus, it became clear that Cmr (MdfA) is the chloramphenicol(and ethidium)/H+ antiporter.

Abstract
A 9-year old boy was admitted to our hospital due to a relapse of acute myelogenous leukemia (AML). A chromosomal analysis at the time of relapse revealed abnormalities in addition to 45, X,-Y, t(8;21) (q22;q22) when AML was first diagnosed. The patient was given granulocyte-colony stimulating factor (G-CSF), cytosine arabinoside (Ara-C) and aclarubicin (CAG therapy), but this treatment regimen was not effective. He was next treated with G-CSF (started 3 days prior to the administration of anticancer drugs), Ara-C, (200 mg/mm2 for 7 days), Etoposide (VP.16, 150 mg/mm2 for 5 days) and Idarubicin (8 mg/mm2 for 5 days) according to the modified Japan Cooperative Protocol ANLL 91 for children. Although his condition had been septic and he had experienced renal and respiratory failure, he achieved a complete remission after 140 days without additional therapy. The patient returned to a condition of health and received a bone marrow transplant from an unrelated donor. We concluded that this treatment regimen is effective for the relapse of AML in children.

Abstract
Decay-accelerating factor (DAF, CD55) is a complement regulatory glycoprotein that expresses the Cromer-system blood group antigens. Two, very rare, inherited DAF-deficiency phenotypes, Inab and Dr(a-), were identified in Japanese propositi. Red cells of the Inab phenotype propositus had no Cromer-system antigens and did not bind monoclonal anti-DAF. The Inab propositus was homozygous for a DAF non-sense mutation, converting the Trp53 codon to a stop codon; her parents were heterozygous for this mutation. This is the same mutation as that previously found in the original Inab phenotype propositus. Haemagglutination-inhibition titrations of the serum of the Inab propositus with soluble-recombinant DAF demonstrated that anti-IFC represents a mixture of antibodies to all four DAF short consensus repeat domains. The Dr(a-) individual had very low levels of Cromer-system antigens and DAF on her red cells. Loss of a TaqI restriction site from DAF exon 5 suggested that she has a previously detected mutation, encoding a Ser165Leu substitution. Red cells of the two propositi did not show abnormal levels of lysis in an acid lysis test, but after blocking of CD59 with monoclonal antibody, Inab phenotype red cells showed more lysis than Dr(a-) red cells, and Dr(a-) cells showed substantially more lysis than control cells.

Abstract
When a human myeloid cell line, U937, was incubated with etoposide (10 micrograms/mL), morphologically apoptotic cells first appeared at 3 hr and increased with time to 50% at 6 hr. Pretreatment of U937 cells for 30 min with a potent tyrosine kinase inhibitor, herbimycin A (10 microM), significantly suppressed the appearance of apoptotic morphological changes. Concomitantly, herbimycin A pretreatment prevented both high molecular weight and internucleosomal DNA fragmentation induced by etoposide. Two major bands at 30 and 66 kDa with enhanced tyrosine phosphorylation inhibited by herbimycin A were detectable after 30 min of incubation with etoposide. In addition, herbimycin A prevented etoposide-induced NF-kappa B activation. The expressions of Bcl-2 and Bax, on the other hand, were not affected by herbimycin A pretreatment. Herbimycin A was also found to inhibit 1-beta-D-arabinofuranosylcytosine-induced apoptotic changes and NF-kappa B activation. These results suggest that activation of tyrosine kinase(s) may play an important role in apoptotic processes induced by a variety of anti-cancer drugs.

Abstract
Intrasplenic heterotransplantation of infantile testis is a conventional method to produce testicular tumors in adult castrated rodents. To avoid possible immunological interference in the tumorigenic process in allografted testis, the parenchyma of testis of Wistar strain rats aged 7 weeks was injected into the spleen of the same rat after bilateral gonadectomy. In 17 of 20 animals testicular neoplasms, resembling gonadal stromal cell tumors in human, developed from the intrasplenic gonadal tissue in the 14th month following transplantation. This autografting technique is feasible to induce testicular neoplasms in granulosa cell tumor category in high incidence, and thus deserves further attention.

Abstract
To produce malignant granulosa cell tumors, ovarian tissue containing 7,12-dimethylbenz[a]anthracene (DMBA) was autografted in the spleen of 20 castrated rats. Adenocarcinoma developed in 8 rats within 6 months from the transplantation. Granulosa cell tumor arose from the intrasplenic graft, in 6 rats at the 14th month. The neoplastic cells were diffusely arranged in sheet showing focal luteinization. In 3 cases extrasplenic spreads were found on the peritoneal surface. Since malignant ovarian tumors seldom develop by intrasplenic grafting alone, the DMBA treatment may contribute to the occurrence of malignant granulosa cell tumor.

Abstract
An apoptosis-resistant mutant (VC-33) was selected from HL-60 by alternating exposure to camptothecin and etoposide. VC-33 cells demonstrated resistance to apoptosis as induced not only by camptothecin and etoposide but by a variety of other agents as well, including 1-beta-D-arabinofuranosylcytosine, hydroxyurea, calcium ionophore (A23187), cycloheximide, and UV irradiation. In an effort to identify the mechanism of such apoptosis resistance, a mRNA differential display analysis was used. Among a total of 12 bands with reduced expression in VC-33 cells, 1 cDNA clone was isolated that was hybridized to the wild-type transcript but not to the VC-33 transcript on Northern blotting. Partial sequence of this gene revealed 98% homology to mitochondrial NADH dehydrogenase subunit 5. When cell growth and intracellular ATP levels under glucose starvation were measured, VC-33 cells were found to be more sensitive than wild-type cells. Thus, NADH dehydrogenase deficiency may contribute, at least in part, to the mechanism of resistance to apoptosis in VC-33 cells.

Abstract
A 55-year-old woman was admitted with urinary frequency. She had undergone augmentation ileocystoplasty due to tuberculous bladder atrophy 37 years previously. Cystoscopy revealed a tumor on the posterior wall which had been augmented with the ileum. Partial cystectomy and bladder reconstruction using a segment of ileum and ascending colon were performed. Gross inspection showed a 15 x 10 mm, papillary tumor on the ileal mucosa near the vesico-ileal anastomosis. Histologically, moderately differentiated adenocarcinoma infiltrating into the muscle layer was surrounded by the normal ileal mucosa. She has been free of recurrence for 2 years postoperatively. This is the 8th case of adenocarcinoma following augmentation ileocystoplasty reported in the Japanese literature.

Abstract
We have demonstrated recently that methotrexate (MTX) inhibits superoxide generation and chemotaxis induced by N-formylmethionyl-leucyl-phenylalanine (fMLP) in neutrophils primed by granulocyte colony-stimulating factor (G-CSF). To extend these observations, we examined the in vitro effect of MTX on fMLP-stimulated superoxide generation and chemotaxis in neutrophils primed by either tumor necrosis factor alpha (TNF-alpha) or bacterial lipopolysaccharide (LPS). MTX inhibited superoxide generation and chemotaxis more efficiently in TNF-alpha- or LPS-primed neutrophils than in unprimed neutrophils. When either hypoxanthine or guanosine was added to the culture medium, the effects of MTX were partially counteracted. Furthermore, MTX caused a significant inhibition of both superoxide production induced by phorbol 12-myristate-13-acetate and chemotaxis induced by interleukin 8 in G-CSF-primed neutrophils. These results may support the hypothesis that neutrophils primed by different stimuli are more susceptible to the inhibitory effects of MTX on superoxide generation and chemotaxis irrespective of chemoattractants. Such an effect can be partly attributed to the perturbation of purine nucleotide biosynthesis.

Abstract
We selected an apoptosis-resistant subline (VC-33) in a human promyelocytic leukemia cell line, HL-60, by alternating exposure to camptothecin (CPT) and etoposide (VP-16). When wild-type (WT) and VC-33 cells were incubated with various concentrations of either CPT or VP-16 for 4 h, VC-33 showed several-fold resistance to apoptosis induced by these agents in comparison with WT cells. VC-33 cells also exhibited cross-resistance to apoptosis induced by 1-beta-d-arabinofuranosylcytosine, hydroxyurea, a calcium ionophore (A23187), cycloheximide, or UV irradiation. The levels of protein-DNA cross-linking induced by CPT or VP-16, and the amounts of ara-CTP generation, tended to be smaller in VC-33 cells, but the difference was not sufficient to explain the difference in the sensitivity to apoptosis. The initial rise of intracellular calcium ions with A23187 and the expression of P-glycoprotein, Bcl-2, and Bcl-Xl were comparable between WT and VC-33 cells. This mutant may represent a new phenotype of resistance to apoptosis induced by a variety of agents, and may thus be useful in the study of the mechanisms of apoptosis.

Abstract
Using an autodigestion method, we investigated endogenous endonuclease(s) in leukemia cells freshly obtained from pediatric patients with various types of leukemia. Endonucleolytic activity was found to cause both high molecular weight and internucleosomal DNA fragmentation at a neutral pH in whole cell lysates of all common acute lymphoblastic leukemia (cALL) blasts, which was Mg2+-dependent and Ca2+-independent. Whole lysates from most acute myeloblastic leukemia (AML) cells possessed similar endonuclease activity, but both Mg2+ and Ca2+ were required for the activity. Our results suggest that leukemia cells of different lineages have distinct constitutive endonucleases, which may play a role in the occurrence of apoptosis in these cells.

Abstract
Primary squamous cell carcinoma of the endometrium (ESCC) is extremely rare. There has been no report of human papillomavirus (HPV) detected in ESCC. A 64-year-old Japanese female underwent total abdominal hysterectomy, bilateral salpingo-oophorectomy, and dissection of the pelvic, para-aortic, and bilateral inguinal lymph nodes. The tumor was confined to the endometrium, without invasion of myometrium or cervix. The endometrium was seen to be replaced by moderately differentiated squamous cell carcinoma, without any adenocarcinomatous element. Polymerase chain reaction amplification produced a 244- to 256-bp DNA fragment from the L1 region of the HPV genome. The amplification products were restricted, and the restricted fragment length polymorphism patterns were analyzed. The squamous cell carcinoma DNA was amplified for each exon, 5 through 8, of the p53 gene. The amplification products were used in single-stranded conformation polymorphism analysis. The tumor described showed the presence of HPV DNA. This amplified fragment was further purified by extraction from agarose gel, and the DNA was sequenced. Comparison of the fragment DNA sequence with known PV sequences showed that it had been amplified from HPV type 31. This is the first detection of HPV DNA in ESCC. Despite previous reports, HPV cannot not be excluded as a possible factor in the development of the malignancy.

Abstract
We encountered a case of ovarian cancer in a 33-year-old, 8-week pregnant woman. Histological examination revealed both a transitive form of ovarian endometriosis with marked decidual changes due to pregnancy and clear cell carcinoma. Benign and borderline clear cell adenofibroma and benign and borderline endometrioid adenofibroma were also found. Parts of these adenofibromas showed transformation to clear cell carcinoma. This case suggests that clear cell carcinoma can arise from clear cell adenofibromas and/or ovarian endometriosis, even in young patients.

Abstract
The patient was initially diagnosed as having non-Hodgkin's lymphoma and was cured following treatment with prednisolone, vincristine, daunorubicin, 1-asparaginase, and cyclophosphamide. Seven years and two months later, he developed osteosarcoma in his right femur. He received chemotherapy consisting of methotrexate, carboplatin, etoposide, and ifosfamide and again obtained remission. After 2 years and 7 months, however, he was found to have pancytopenia with morphological abnormalities in the erythroid and myeloid series. Diagnosis of myelodysplastic syndrome (MDS) was made. Cytogenetic analysis of bone marrow cells revealed -5 and -7, which is typical for secondary MDS. This is a rare case of third malignancy presumably caused by alkylating agents.

The establishment and characterization of a new human endometrioid adenocarcinoma cell line (KOC-8e) derived from the malignant ascites is described. The original tumor at the initial operation showed positive in TPA, and SLX immunohistochemically. By contrast, recurred tumor showed positive for CA125, TPA, SLX, MUC-1, and p53. In addition, the heterotransplanted tumor showed positive for CA125, TPA, SLX, MUG-1, and p53. The DNA index was similar in the primary, recurred, and nude mouse tumor ranging between 1.93 and 2.05. The tumor growths were suppressed dose dependently by CDDP and CPT-11. CA125 showed useful as a tumor marker of this tumor, however, the nude mice had detectable tumor without elevation of CA125 after low dose application of CDDP and CPT-11. Thus, clinical determination of chemotherapeutic effect and residual tumor cannot be made only by CA125. KOC-8e cells could be useful to study histological analysis and chemosensitivity.

Abstract
Magnetic resonance cholangiopancreatography (MRCP) was performed in 35 patients to evaluate the feasibility of its use as a postsurgical imaging technique after resection of the pancreas. The surgical procedures performed were: pancreatoduodenectomy in 22 patients, segmental pancreatectomy in 1, distal pancreatectomy in 7, and pyrolus-preserving pancreatoduodenectomy in 5. The pancreatic duct was shown in its entirety in 24 of the 35 patients (68.6%) and was partially visualized in 8 patients (22.9%), but the intrahepatic and extrahepatic bile ducts were visualized completely in all patients. Furthermore, MRCP was able to demonstrate lesions in 3 of 6 patients who had shown clinical evidence of recurrence. The visualization of the pancreatic and bile duct system was satisfactory despite anatomical changes brought about by resection of the pancreas. Thus, we conclude that MRCP is an appropriate follow-up screening test for patients with suspected abnormalities of the biliary and pancreatic duct system.

Abstract
OBJECTIVE We examined uterine tissue samples obtained from premenopausal women with uterine leiomyoma treated with gonadotropin-releasing hormone agonist (GnRHa) to investigate the mechanism of the effects of GnRHa. STUDY DESIGN Surgically resected myoma tissue obtained from 26 premenopausal patients with uterine leiomyoma treated with GnRHa, 20 premenopausal patients with uterine leiomyoma who did not receive GnRHa treatment, and 15 postmenopausal women with uterine leiomyoma were examined histologically. RESULTS GnRHa treatment reduced the size of uterine leiomyomata and induced significant hyaline degeneration in tumor tissue. Le(Y)-antigen expression was detected in 18 (69.3%) of 26 GnRHa-treated patients (P < 0.02) and in 12 (80.0%) of 15 postmenopausal women (P < 0.05), but in only eight (40.0%) of the 20 premenopausal patients who did not receive GnRHa. Apoptotic cells, detected by the nick-end labeling method were observed in 14 patients (53.8%) in the GnRHa-treated group, 10 patients (50.0%) in the non-treated group, and 12 postmenopausal women (80.0%). CONCLUSION Our findings suggest that induction of apoptosis may be a mechanism of the effect of GnRHa in leiomyoma.

Abstract
It has been reported that the antitumor effect of CPT-11 is manifested through the inhibition of topoisomerase I by SN-38 which is an active metabolite of CPT-11 produced by intracellular carboxylesterase, and that CPT-11 is effective against recurrent ovarian carcinoma. We investigated the antitumor effect and adverse reactions in the combined therapy with CPT-11 and CDDP in patients with prior chemotherapy for recurrent carcinoma, and in 7 patients without prior chemotherapy, consisting of 4 patients with postoperative adjuvant chemotherapy for clear cell carcinoma and 3 patients with metastatic ovarian carcinoma. CDDP was administered on day 1 and CPT-11 was administered three times on days 1, 8 and 15. The dose of both CDDP and CPT-11 was 50 mg/m2 or 60 mg/m2. Adverse reactions were investigated in all patients and the antitumor effect was assessed in 12 patients with recurrent carcinoma who had measurable lesions. (1) The DLF was neutropenia. The neutrophil count nadiar occurred on day 18 or 19. Grade 3 or 4 adverse reactions were observed in 60% or more of the patients, but they disappeared following short term administration of G-CSF. In patients with recurrent carcinoma given CDDP and CPT-11 at 60 mg/m2, the incidence of grade 3 or 4 adverse reactions and number of occasions on which CPT-11 administration had to be postponed were higher than those in patients given 50 mg/m2. (2) Mild platelet reduction was observed. (3) Grade 3 or 4 diarrhea was observed in 3.2% of patients with recurrent carcinoma and in 7.7% of patients with metastatic ovarian carcinoma. (4) The antitumor effect was evaluated in 12 patients with recurrent carcinoma: CR in 2 patients. PR in 3, NC in 6, and PD in one. The response rate was 41.7%. (5) An antitumor effect was observed in 2 patients with serous carcinoma and in one patient each with mucous carcinoma, clear cell carcinoma and endometrial carcinoma. In conclusion, adverse reactions caused by the combination therapy with CPT-11 and CDDP (CPT-11: 50-60 mg/m2 on days 1, 8 and 15, CDDP: 50-60 mg/m2 on day 1) can be relieved by short term administration of G-CSF and it is suggested that the combination therapy may be effective in treating ovarian carcinoma.

Abstract
Treatment of circulating human neutrophils with recombinant human granulocyte colony-stimulating factor (rhG-CSF) for 30 min augmented superoxide generation and chemotaxis induced by N-formylmethionyl-leucyl-phenylalanine (fMLP) in a dose dependent manner. When neutrophils were treated with 1 microM of methotrexate (MTX) for 60 min after incubation with rhG-CSF (10 ng/ml), the effects of rhG-CSF on superoxide generation and chemotaxis were inhibited by approximately 49 and 29%, respectively. Although inhibitory effects of MTX were also seen in neutrophils not pretreated with rhG-CSF, the degree of inhibition was much less. The addition of either hypoxanthine or guanosine at a concentration of 100 microM to the culture medium significantly attenuated the effects of MTX. However, in neutrophils obtained from a patient with Lesch-Nyhan syndrome, which lacked hypoxanthine-guanine phosphoribosyl transferase activity neither hypoxanthine nor guanosine had any rescue effect. These results suggest that MTX inhibits superoxide generation and chemotaxis in rhG-CSF-activated neutrophils, at least in part, by disturbing purine nucleotide biosynthesis.

Abstract
We present a challenging case of differential diagnosis of leiomyosarcoma of the small intestine in a patient presented with a pelvic mass. This 43-year-old Japanese woman complained of hypermenorrhea and was diagnosed as myoma uteri. She underwent partial resection of the ileum with a primary end-to-end anastomosis, omentectomy, and appendectomy, as well as a simple hysterectomy and bilateral salpingo-oophorectomy. CT and MRI indicated an intestinal tumor at the gaseous site. The histological diagnosis was leiomyosarcoma of the small intestine and leiomyoma of the uterus. Although such leiomyosarcomas are rare, they can appear as pelvic masses and must be differentiated from gynecologic disease. Preoperative CT and MRI of the abdomen were useful in obtaining the diagnosis.

Abstract
We present a rare case of a 31-year-old woman with a mucinous ovarian tumor with sarcoma-like mural nodules. The epithelial elements consisted of a mixture of benign, borderline-malignant, and mucinous adenocarcinoma; the sarcoma-like mural nodules consisted of pleomorphic and epulis-like cells. The lesion was resected for an ovarian tumor. In an immunohistochemical study, these cells stained for lysozyme and vimentin. The patient received 2 courses of cisplatin (100 mg/m2). There was no evidence of disease at a second-look laparotomy after 1 year, and none upon examination 6 years after the initial operation. The mural nodules might be of non-epithelial origin. The prognosis of patients with this rare lesion appears favorable, according to this and previous reports.

Abstract
The number of reported cases of malignancy developing in growth hormone (GH) users worldwide has increased to more than 40. However, the causal relationship between GH administration and the occurrence of malignancies is still uncertain. We investigated somatic cell mutation frequencies (Mfs) or variant frequency (Vf) at three gene loci in patients with pituitary dwarfism receiving GH therapy to clarify the genetic effect of GH. Eighty-eight patients receiving GH therapy for at least 3 months and 42 age-matched healthy controls were studied. Mfs at hypoxanthineguanine phosphoribosyltransferase (HPRT) and T-cell receptor (TCR) loci in GH users were not significantly higher than in the controls. Although a few patients seemed to have a slightly increased Vf at the glycophorin A (GPA) locus, the difference was not statistically significant. In addition, there was no tendency for the Mfs (Vf) at these loci to increase with the duration of the GH therapy. These data seem to exclude the possibility that GH induces genetic instability in patients with pituitary dwarfism who are receiving GH therapy.

Abstract
We encountered a rare case of metachronous tumors in a 57-year-old Japanese housewife who presented with an ovarian granulosa cell tumor 22 years after receiving treatment for endometrial stromal sarcoma. Treatment consisted of a total abdominal hysterectomy and left salpingo-oophorectomy followed by 40 Gy whole abdominal irradiation. Since the second tumor occurred in the ovary that had been previously irradiated to treat the first metachtonous neoplasm, the present case can help to improve our understanding of the histogenesis of granulosa cell tumors.

Abstract
Selective delivery of a high level of cisplatin (CDDP) to the omentum, intraperitoneal disseminated tumors and lymph nodes was studied using a dosage form of CDDP-activated carbon. Although intraperitoneal CDDP-activated carbon delivered much higher levels of CDDP to the omentum, tumors and lymph nodes, a primary burst phenomenon of CDDP occurred just after administration. This indicates that activated carbon is an unsuitable particle to provide a slow steady release of CDDP.

Abstract
MAGE genes encoding tumor-rejection antigens recognized by cytotoxic T lymphocytes are expressed at the mRNA level in various malignant tumors. We have investigated the expression of genes MAGE-1, -2, -3/-6 and -4a/-4b at the mRNA level in malignant and non-malignant ovarian tumors as well as in normal ovaries by reverse transcription-polymerase chain reaction. MAGE-1, -2, -3/-6 and -4a/-4b were expressed in 12, 5, 11 and 4 of 58 malignant tumors, respectively. The majority of these MAGE-mRNA-positive tumors were histologically surface-epithelial-stromal tumors, in particular serous adenocarcinomas. They mostly consisted of either advanced-stage or recurrent tumors. In contrast, neither benign tumors nor normal ovaries expressed any of the MAGE genes investigated. A 46-kDa MAGE-1 protein was identified in MAGE-1-mRNA-positive serous adenocarcinomas by immunoblot analysis with polyclonal anti-MAGE-1 antibody. These results provide important information for specific immunotherapy of ovarian serous adenocarcinomas with MAGE gene products.

Abstract
OBJECTIVE Preoperative CT or MRI findings were compared with the results of staging the laparotomy to evaluate the accuracy of CT or MRI for detecting pelvic and para-aortic lymph-node metastases. METHODS In evaluating CTs in 95 ovarian carcinomas, we examined plain and contrast images made in 1- to 1.5-cm-thick slices from the pubis to the xiphoid process. Lymph nodes 1.5 cm or larger were considered to be positive. MRIs of 60 uterine corpus carcinomas utilized T1-weighted contrast, T2-weighted, and short-inversion time inversion-recovery (STIR) images. RESULTS CT had a sensitivity of 60.9% and a specificity of 93.1%. The positive and negative predictive values were 73.7% and 88.2%, respectively. The diagnostic accuracy of CT for detecting para-aortic lymph-node metastases exceeded that for pelvic node metastases. The results of MRI indicated that the T1-weighted image and STIR image were the most accurate in identifying metastatic nodes. CONCLUSIONS These results indicate that the most practical approach might be to search for enlarged lymph nodes by CT, and to follow-up with MRI when CT scans are questionable.

Abstract
The incidence and transplantability of ovarian teratoma in LT/Sv mice were examined following cisplatin treatment at the age of 16 days, and compared to those in the control group. Cisplatin had not affected the emergence of egg cleavage, which simultaneously appeared in the mouse ovaries in both groups. Although 7 teratomas, occasionally transplantable, developed in the control mice aged over 30 days, only 2 tumors occurred in cisplatin-treated mice at the age of 120 days and they were not transplantable. The results suggest that cisplatin might influence the tumorigenic process after egg cleavage, or transplantability of teratoma.

Abstract
OBJECTIVE Experimental chemotherapy was conducted to investigate the combined effect of Schizophyllan (SPG) and Cisplatin (CDDP). METHODS Rats with 7,12-dimethylbenz(a)anthracene (DMBA)-induced ovarian adenocarcinoma received SPG and/or CDDP, were observed for the anti-tumor effect of the drugs and were subjected to immunohistochemical study. RESULTS 1) Tumor reduction was enhanced by the combined use of SPG and CDDP; 2) The survival rate of rats given SPG alone was significantly higher than that of the control rats, and treatment with SPG combined with CDDP tended to improve the survival rate; 3) Immunohistochemically, an infiltrative increase in cytotoxic T-lymphocytes (CTL) was induced, although the development of helper T-cells and macrophages was immunohistochemically weak at the tumor site. CONCLUSION The administration of SPG enhanced the anti-tumor effect of CDDP.

Abstract
Ovarian serous adenocarcinoma with AFP production is very rare. A case involving a 66-year-old woman with an elevated serum AFP level without detectable hepatic involvement. AFP-positive cells were seen in the tumor at the second surgery. Fifty-seven percent of serum AFP from the patient bound Con A, whereas 43% did not. Similarly, 54% of the tumor fluid also bound Con A. These suggest that the serum AFP was similar to that of gastrointestinal tumors and yolk-sac tumors.

Abstract
Sixty-three patients with stage Ic-IV ovarian cancer received cisplatin, epirubicin and ifosfamide chemotherapy following a staging surgery between 1985 and 1992. The optimal surgery (without macroscopic residual was completed in 44 patients including 12 stage III cases. A 5-year survival of 97.5% was obtained for the optimal cases; whereas that for suboptimal cases was only 24.0%. From the results, the regimen proved to be a promising adjuvant therapy for ovarian cancer after optimal surgery; moreover a need for a drastic amelioration of strategy is emphasized in the treatment of advanced ovarian cancer with extensive metastases.

Abstract
1-beta-D-arabinofuranosylcytosine (ara-C) (2 microM) can induce apoptosis in a human myeloid leukemia cell line, U937, after 4 h of incubation. Pretreatment of cells with aphidicolin (2 microM) augments ara-C-induced apoptosis, since it was first observed at 0.4 microM ara-C and became more intense at 2 and 10 microM. Although aphidicolin itself had a marginal effect on c-jun expression, it significantly augmented ara-C induced c-jun upregulation by shortening the lag time and lowering ara-C concentrations necessary for the induction of detectable c-jun transcripts. Aphidicolin and ara-C acted synergistically to increase NF-kappa B DNA binding activity as determined by an electrophoretic mobility shift assay. Expression of c-myc was slightly increased through the DNA degradative phase, and was then downregulated. Thus, the activation of NF-kappa B and c-jun expression seems to be well correlated with the potentiation by aphidicolin of ara-C-induced apoptosis.

Abstract
We have selected calcium ionophore (A23187)-resistant cells (AR-7) in a human promyelocytic leukemia cell line, HL-60. AR-7 showed approximately 8.5-fold resistance to A23187 compared with the wild type cells after continuous exposure for 3 days. AR-7 had cross resistance to ionomycin (4.6-fold) and thapsigargin (340-fold) which can also increase intracellular Ca++. Similar magnitude of resistance to apoptosis, as defined by characteristic morphology and internucleosomal DNA fragmentation, induced by these agents was observed after 4 hr of incubation. However, both the elevation of intracellular Ca++ following stimulation with various concentrations of A23187 and the sensitivity to anti-cancer agents including etoposide, 1-beta-D arabinofuranosylcytosine, and hydroxyurea were comparable between the two cell types. This cell line is considered to be useful for exploring the mechanism(s) of cell death, especially apoptosis, induced by calcium ionophore.

Abstract
An ovarian hepatoid carcinoma associated with minimal alpha-fetoprotein (AFP) production is described. The tumor involved both ovaries, and had metastasized to the omentum, uterus and retroperitoneal lymph nodes. The neoplastic cells were arranged in sheets, had abundant eosinophilic cytoplasm, central nuclei and distinct cellular borders. Despite the morphologic similarity to the histology of a hepatocellular carcinoma, elevation of the serum AFP level was minimal, at 74.0 ng ml-1 (normal range: under 20 ng ml-1), and the value normalized after surgery and subsequent chemotherapy. An immunohistochemical technique revealed focal staining for albumin in the tumor tissue and AFP in the uterine metastasis. Since the primary tumor itself did not stain for AFP, it is suggested that there may be hepatoid ovarian carcinomas without AFP production, a situation found in some hepatocellular carcinomas.

Abstract
This study focused on unusual histologic features observed in 2 relapsed Brenner tumors. Case 1: A 67-year-old woman had a malignant Brenner tumor. The tumor relapsed was squamous-cell carcinoma. Case 2: A 51-year-old woman had a proliferating and malignant Brenner tumor with mucinous metaplasia. The relapsed tumor was a well-differentiated mucinous adenocarcinoma. These cases suggest that: (1) the relapsed tumor cells survived chemotherapy; and (2) the relapsed tumor cells transformed.

Abstract
Calcium ionophore (A23187)-induced high molecular weight (HMW) and internucleosomal DNA fragmentation were investigated in human leukemia cell lines. An apoptosis-sensitive cell line, HL-60, showed HMW, internucleosomal DNA fragmentation and morphological changes of apoptosis by A23187. MOLT-4, which is resistant to apoptosis, exhibited only HMW DNA fragmentation and died of necrosis under the same conditions. Autodigestion experiments suggested the endonucleolytic activity to cause HMW fragmentation in the cytoplasm of both cell lines. The activity was more dependent on Mg2+ than Ca2+ in HL-60, whereas it was Ca(2+)-dependent in MOLT-4. These results suggest that HMW DNA fragmentation is not specific to apoptosis.

Abstract
An unusual adenofibroma of the uterine cervix is reported. The cervix was bulkily enlarged but did not have a polypoid appearance. The neoplastic epithelium was in continuity with the covering epithelium of the cervix and consisted predominantly of endometrioid cells which proliferated to form numerous glandular structures of irregular size and shape. The glandular component resembled an endometrial hyperplasia, and was set in an abundant fibrous stroma which was moderately cellular and hyalinized. Both the epithelial and mesenchymal cells lacked cytologic atypia. Despite its benign appearance, the tumor occupied almost all the uterine cervix and extended into the upper vaginal wall. The epithelial cells showed diffuse positive staining for CA19-9 and were focally positive for carcinoembryonic antigen. The presence of dense periglandular fibrosis distinguished the present case from a minimal deviation adenocarcinoma of endometrioid type.

Abstract
We treated an 11-year-old girl with spinal cord compression near an epidural tumor. Bone marrow examination confirmed the diagnosis of acute lymphoblastic leukemia (ALL). To reduce the compression we treated her immediately with high-dose dexamethasone and vincristine administered intravenously along with local irradiation. Three days later, radiation was discontinued because magnetic resonance imaging showed that the spinal cord compression was reduced. Complete remission has continued without evidence of neurologic sequelae for more than 3 years since diagnosis. Rapid reduction of the blasts resulted in tumor lysis syndrome, which was treated with conventional management and additional diuresis without hemodialysis. Epidural spinal cord compression in childhood ALL can be treated effectively with systemic chemotherapy and local radiotherapy without laminectomy.

Abstract
A case of spontaneous rupture of the right kidney caused by a primary renal pelvic tumor is reported. A 57-year-old man complaining of right flank pain and gross hematuria was referred to our hospital in November 1992. In 1982, transurethral resection of the bladder tumor (TUR-Bt) and vesical instillation with mitomycin-C (MMC) had been performed at another hospital for recurrent bladder tumor. In 1988, the excretory urogram showed right hydronephrosis in the absence of a bladder tumor. In 1992, the excretory urogram revealed nonvisualization of the right kidney and obscurity of the right psoas muscle shadow. On the retrograde pyelogram, the upper calyx was irregular and the middle and lower calices were not clearly visualized. Selective renal arteriography demonstrated loss of continuity between the middle portion and lower poles. Right nephroureterectomy with bladder cuff was performed. The severely dilated pelvis contained a large amount of coagula and a papillary tumor. The thin renal parenchyme was lacerated at the lower pole. Histopathological findings revealed noninvasive transitional cell carcinoma. The present case represents the 6th spontaneous renal rupture caused by a renal pelvic tumor reported in Japan.

Abstract
The present study was designed to determine the effects of sex steroid hormones (estradiol, progesterone), gonadotropins (FSH, hCG), and gonadotropin releasing hormone agonist (GnRHa: Buserelin) on the proliferation of the ovarian serous adenocarcinoma cell line KOC-2S in vitro. The results showed: 1. The colony formation rate and fraction growth in the colony stem cell assay were suppressed by estradiol (5,000 pg/ml) and progesterone (50 ng/ml). The colony formation rates were 2.96% (control); 2.49%, 0.99% (estradiol: 500 pg/ml, 5,000 pg/ml); 2.58%, 0.53% (progesterone: 5.0 ng/ml, 50.0 ng/ml); 4.80%, 3.34% (hCG: 10 mIU/ml, 100 mIU/ml); and 1.79%, 2.96% (GnRHa: 1.0 ng/ml, 10 ng/ml). 2. The doubling time (DT) in the growth inhibition test was shortened by FSH and the saturation density (SD) became greater. The SD was suppressed by hCG. 3. The cytogenic features of the cells treated with FSH, estradiol and GnRHa did not show obvious morphologic change. The spontaneous floating cells were observed following treatment with progesterone. Cytoplasmic enlargement was observed following treatment with hCG. 4. Neither erb B nor erb B-2 was expressed in KOC-2S cells, and neither was induced by sex steroid hormones, gonadotropins or GnRHa.

Abstract
In the present study, the role of endogenous prostanoid synthesis in gastric mucosa in the healing of chronic gastric ulcers was investigated. Nineteen patients were divided into two groups in accordance with healing state after one month of treatment with cimetidine only: "healed group" and "unhealed group". Biopsy specimens taken from the mucosa around the ulceration (damaged gastric mucosa) and at a distance from the ulceration (normal gastric mucosa) at endoscopy prior to treatment were homogenized, and the mucosal prostanoid synthesis was determined using [14C]arachidonic acid. The mean value of prostaglandin E2 synthesis in the normal gastric mucosa of the healed group was 60% higher than in that of the unhealed group, but the difference was not significant. However, prostaglandin E2 synthesis in the damaged gastric mucosa of the healed group was 117% higher than in that of the unhealed group. The same tendency was observed for prostaglandin D2 and 6-keto prostaglandin F1 alpha synthesis as for prostaglandin E2. In our study it was demonstrated that there is a good correlation of prostaglandin synthesis in the damaged mucosa with healing of chronic gastric ulceration. Furthermore, our study indicated that prostaglandin synthesis, especially in damaged mucosa, might be important in the healing of gastric ulceration.

Abstract
A total of 6,457 autopsy protocols were reviewed to identify 70 women who died of ovarian cancer. 1. Epithelial tumors were the most common tumor (74%). Twenty% were germ cell tumors. There were two cases each of sarcoma and stromal cell tumors. 2. The patients with germ cell tumors were younger than those with epithelial tumors. The duration of the epithelial tumor disease was longer than that of germ cell tumor. 3. The most common mechanism of death was carcinomatosis (69%). Eight of 70 patients (11%) had respiratory failure. One case of subacute cor pulmonale was due to tumor embolization. One case had a rupture of the portal vein. 4. The peritoneum was most frequently involved in every tumor (87%). The liver was the second most frequent site (73%). Other frequent metastatic sites included the lungs (44%), and spleen (47%). Lymph nodes including the paraaortic, pelvic and mesenteric were also very frequent metastatic sites. 5. CDDP containing regimens were used in 33 cases (47%). FAMT regimen was the second most common treatment (15.7%). Another common treatment is whole abdominal radiotherapy (14%). The patients treated with the CDDP containing regimen had a significantly longer survival time (23.4 months) than those treated with FAMT (19.2 months) and others (13.6 months). 6. For metastasis to the lungs, spleen and mesenteric lymph nodes the patients treated with the CDDP containing regimen were more numerous than those treated without CDDP. For metastasis to the kidneys, the patients treated without CDDP were more numerous than those treated with CDDP containing regimens.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
A 68-year-old woman presented a one-month history of lower abdominal pain and weight loss, and was admitted to our hospital. On physical examination, a large hard mass was palpated in her right lower abdomen. An ultrasonograph and computed tomographic (CT) scan revealed a right ovarian tumor that measured 6.9 x 4.9 cm in size. A total hysterectomy and bilateral salpingo-oophorectomy were performed. The postoperative diagnosis of the tumor was squamous cell carcinoma (SCC) of the ovary. She died of infection and disseminated intravascular coagulation 5 months after surgery. The clinical and autopsy examinations did not show the primary lesions of SCC except in the right ovary. Mature cystic teratoma, Brenner tumor and endometriosis, which are ordinary regarded as the histogenesis of ovarian SCC, were not found, but a few surface epithelial inclusion cysts with squamous metaplasia were observed in non-cancerous area of the right ovary, and the contiguous transition from the metaplastic cyst wall to SCC was confirmed by stepwise serial sections. The present case suggests that the surface epithelium of ovary could be the fourth possibility in the histogenesis of the ovarian SCC.
