Abstract
Mycobacterium abscessus subsp. abscessus (MABA) is refractory and sometimes fatal especially in an immunocompromised patient. Also, MABA-associated pneumothorax is an extremely rare complication. We report a case of MABA pulmonary infection complicated pneumothorax treated successfully. A 69-year-old Japanese female with immunosuppressed systemic sclerosis-associated interstitial lung disease experienced left-sided secondary spontaneous pneumothorax. MABA was detected in the pleural effusion and blood culture. Microbial sensitivity test showed the MABA was sensitive to only amikacin, sitafloxacin, and clofazimine. Combination therapy with these antibiotics including azithromycin achieved remission within three weeks. In the treatment of MABA infection, compliance with microbial sensitivity test is crucial.

Abstract
X chromosome inactivation (XCI) is an essential mechanism for gene dosage compensation between male and female cells in mammals. The Okinawa spiny rat (Tokudaia muenninki) is a native rodent in Japan with XX/XY sex chromosomes, like most mammals; however, the X chromosome has acquired a neo-X region (Xp) by fusion with an autosome. We previously reported that dosage compensation has not yet evolved in the neo-X region; however, X-inactive-specific transcript (Xist) RNA (long non-coding RNA required for the initiation of XCI) is partially localized in the region. Here, we show that the neo-X region represents an early chromosomal state in the acquisition of XCI by analyses of heterochromatin and Barr body formation. We found no evidence for heterochromatin formation in the neo-X region by R-banding by acridine orange (RBA) assays and immunostaining of H3K27me3. Double-immunostaining of H3K27me3 and HP1, a component of the Barr body, revealed that the entire ancestral X chromosome region (Xq) showed a bipartite folded structure. By contrast, HP1 was not localized to the neo-X region. However, BAC-FISH revealed that the signals of genes on the neo-X region of the inactive X chromosome were concentrated in a narrow region. These findings indicated that although the neo-X region of the inactive X chromosome does not form a complete Barr body structure (e.g., it lacks HP1), it forms a slightly condensed structure. These findings combined with the previously reported partial binding of Xist RNA suggest that the neo-X region exhibits incomplete inactivation. This may represent an early chromosomal state in the acquisition of the XCI mechanism.

Abstract
We examined the efficacy of embryoid bodies from 6-day induced pluripotent stem cells an in vivo sepsis model. Injection of embryoid bodies to septic mice improved the condition of their lungs and significantly increased their survival rate. Although embryoid bodies secretedsphingosine-1-phosphate in vitro, its serum levels in mouse plasma were significantly reduced compared to that in the control (untreated mice receiving PBS). Low concentrations of sphingosine-1-phosphate protected endothelial cells, while high concentrations disrupted endothelial barrier integrity. Therefore, exogenous sphingosine-1-phosphate secreted by embryoid bodies during early stage of sepsis might down regulate endogenous production of sphingosine-1-phosphate. Inhibition of excessive sphingosine-1-phosphate release protects against endothelial injury and suppresses a vicious cycle of inflammatory reactions. The obtained results open new prospects in induced pluripotent stem cells-based therapy for sepsis.

Abstract
Nitric oxide produced by inducible nitric oxide synthase (iNOS) regulates sepsis-induced hypotension. During septic shock, interleukin (IL)-1β is synthesized in endothelial cells and smooth muscle cells by endotoxin. Ethanol (EtOH) suppresses endotoxin-induced hypotension. The present study aimed to elucidate the effect of EtOH on gradual relaxation and iNOS expression induced by IL-1β in isolated rat superior mesenteric arteries (SMAs). Exposure to IL-1β-induced contraction in SMA rings, followed by a gradual relaxation of phenylephrine precontracted tone. Contraction was abolished by indomethacin (IM), cycloheximide (Chx), and endothelium denudation. In contrast, the gradual relaxation was abolished by NOS inhibitors, Chx, endothelium denudation, and inhibited by EtOH (50 and 100 mM). However, IM had no effect on relaxation. Western blot analysis demonstrated that iNOS expression was induced by IL-1β and was inhibited by EtOH and endothelium denudation. Furthermore, messenger RNA expression of iNOS, but not endothelial NOS, was inhibited by EtOH. These data suggest that IL-1β-induced contraction is mediated by thromboxane A2, whereas IL-1β-induced relaxation occurs via NO derived from iNOS. The endothelium plays an important role in vasorelaxation. Taken together, EtOH inhibits IL-1β-mediated vasorelaxation by suppressing endothelium iNOS expression. This study provides the first evidence of EtOH -induced inhibition of IL-1β-mediated vasorelaxation.

Abstract
Processing technology using an extreme ultraviolet light source, e.g., next-generation lithography, requires next-generation high-accuracy mirrors. As it will be difficult to attain the degree of precision required by next-generation high-accuracy mirrors such as aspherical mirrors through conventional processing methods, rapid progress in nanomeasurement technologies will be needed to produce such mirrors. Because the measuring methods used for the surface figure measurement of next-generation mirrors will require high precision, we have developed a novel nanoprofiler that can measure the figures of high-accuracy mirrors without the use of a reference surface. Because the accuracy of the proposed method is not limited by the accuracy of a reference surface, the measurement of free-form mirrors is expected to be realized. By using an algorithm to process normal vectors and their coordinate values at the measurement point obtained by a nanoprofiler, our measurement method can reconstruct three-dimensional shapes. First, we measured the surface of a concave spherical mirror with a 1000-mm radius of curvature using the proposed method, and the measurement repeatability is evaluated as 0.6 nm. Sub-nanometer repeatability is realized, and an increase in the repeatability would be expected by improving the dynamic stiffness of the nanoprofiler. The uncertainty of the measurement using the present apparatus is estimated to be approximately 10 nm by numerical simulation. Further, the uncertainty of a Fizeau interferometer is also approximately 10 nm. The results obtained using the proposed method are compared with those obtained using a Fizeau interferometer. The resulting profiles are consistent within the range of each uncertainty over the middle portions of the mirror.

Abstract
We studied the association between four novel single nucleotide polymorphisms (SNPs) in the promoter region of V1aR gene and essential hypertension in 620 Japanese subjects (365 hypertensives and 255 healthy). A significant association was found between one of the genotypes and alleles at SNP -6951 and hypertension in a subsample of nonobese individuals. This association demonstrated an independent risk for nonobese hypertension.

Abstract
We investigated maternal IgM secretion in the ovary and the absorption of IgM by fetuses in a viviparous fish, Neoditrema ransonneti (Embiotocidae). Serum IgM, whose molecular weight was approx. 820k, was purified by two steps of gel filtration chromatography. Immunohistochemistry and Western blotting revealed that IgM was secreted from the epithelia of the ovigerous lamellae of pregnant females into ovarian cavity fluid. The IgM-secreting activity of ovigerous folds showed notable changes according to the reproductive stage. In fetuses, IgM was absorbed as macromolecules by enterocytes of the hypertrophied hindgut. IgM in the fetal blood was also demonstrated, although its concentration remained low during gestation. These findings suggest that IgM was transported from the maternal tissues to embryos via a unique pathway in N. ransonneti.

Abstract
Intrauterine growth restriction (IUGR) has a multifactorial pathogenesis and is an important cause of perinatal mortality. The relationship between fetal weight and placental blood flow in an animal model of IUGR has been investigated, showing that fetal growth is regulated by placental blood flow. The aim of the present study was to determine whether ischemia-reperfusion (I/R) injury stimulates the prostaglandin E2 (PGE2) system or the vascular endothelial growth factor (VEGF) system in the placenta of a rat IUGR model. COX-2 is reported to be involved in ischemic damage in many organs. There are 4 types of PGE2 receptor (EP1, EP2, EP3 and EP4). It is well known that EP1 and EP3 is associated with vasoconstriction. In the present study, vessels were occluded in the right uterine horn on day 17 of pregnancy in rats, and the clamps were removed after 30 min of ischemia. At 24h, 48 h, and 5 days after I/R injury, the live fetuses and placentas were obtained by cesarean section. This study revealed that I/R injury caused IUGR 5 days after the treatment. COX-2 expression and EP3 receptor expression were significantly elevated at 24h after I/R injury, but VEGF mRNA expression was not altered in the placenta from the ischemic horn compared with the non-ischemic horn. These results suggested that induction of the COX-2-EP3 system in the placenta may be one of the causes of IUGR induced by uterine ischemia, because the EP3 receptor and PGE2 are well known to mediate vasoconstriction in many organs.

Abstract
Between 1989 and 2002, 28 patients with locally advanced cervical adenocarcinoma (bulky IB-IIIB) were recruited for a pilot study aimed at evaluation of the effectiveness of neoadjuvant chemotherapy with cisplatin, aclacinomycin-A, and mitomycin-C (PAM), followed by radical surgery. This regimen was administrated intra-arterially or intravenously. In addition to patients treated with PAM, we retrospectively analyzed the prognoses of 26 patients in stage I and II, who had been treated between 1975 and 1981 with radical surgery with/without radiation therapy. Twenty-eight patients received PAM therapy as neoadjuvant chemotherapy, and 75.0% of the 16 intra-arterially infused patients showed a response, as did 66.7% of the 12 intravenously infused patients. There was a significant difference in the 5-year prognosis of stage II (PAM group, 72.9%; without-PAM group, 36.4%). The results suggest that, as the free space in the parametrium is widened by neoadjuvant chemotherapy with PAM, it is possible that the tumor could be completely resected by radical hysterectomy. Thus, neoadjuvant chemotherapy with PAM is expected to improve the survival rate of patients with advanced cervical adenocarcinoma by the preliminary study. However, the survival rates of stage II with lymph node metastasis in the without-PAM group seem low, and we must also consider that the various technologies to evaluate and treat the cervical adenocarcinomas, e.g. computed tomography, magnetic resonance imaging, and surgical equipments, had improved during 1989-2002 than was the scenario during 1975-1981, and these improvements contributed to better prognosis. A prospective-randomized study is needed to assess the value of this approach compared with standard management.

Abstract
The purpose of this study was to review magnetic resonance imaging (MRI) and pathologic features of primary malignant melanoma (melanoma) in the female genital tract. We retrospectively evaluated MRI in six women with melanoma of the genital tract. The signal intensity of the tumor on T1-weighted images (WI) was compared with the amount of melanin granules in hematoxylin-eosin stained sections of resected specimen. On T1WI, four melanomas showed a high signal intensity, one intermediate, and one low. The four melanomas with a high signal intensity on T1W1 were rich in melanin granules, while the one intermediate tumor had few granules. The other one was amelanotic. We believe that a high signal on T1WI is characteristic of primary melanotic melanoma of the female genital tract. Our findings suggest that it is strongly influenced by the presence of melanin granules.

Abstract
We experienced a case of hemorrhagic infarction of the ovarian fibroma and that indicated the characteristic following appearance: exhibiting a high signal intensity area observed at the periphery of mass on T1-weighted MRI (magnetic resonance imaging). It was thought that this appearance developed because hemorrhagic infarction was caused by subacute ovarian torsion. This is a useful finding for suspecting hemorrhagic infarction preoperatively.

Abstract
We reported previously that 7-hydroperoxycholesterols, 7 alpha- and 7 beta-hydroperoxycholest-5-en-3 beta-ol (7 alpha-OOH and 7 beta-OOH), indicated lipid peroxidation. In the present study, we measured not only 7-hydroperoxycholesterols but also oxysterols (7 alpha- and 7 beta-hydroxycholesterol, 7 alpha-OH, and 7 beta-OH) and 3 beta-hydroxycholest-5-en-7-one (7-keto) in the brains of rats that underwent either a sham operation (control), hypoxia, or CO inhalation (1005 ppm) at 37 degrees C for 90 min followed by 48 h of recovery. The levels of 7-hydroperoxycholesterols, 7 beta-OH, and 7-keto were low in the hypoxia group, while the levels were unaltered in the CO group compared with the controls. Among the three groups of CO inhalation, these levels were high in the hyperthermia group (39 degrees C), and the 7-hydroperoxycholesterols were low in the hypothermia group (32 degrees C), compared with the control group. The blood O(2) saturation was almost normal in the hypothermia group, while it was similarly low in the hyperthermia and normothermia groups. The temperature-dependent lipid peroxidation in the brain after CO inhalation and recovery can not be explained by hypoxia due to CO-hemoglobin formation, but may contribute to the delayed neuronal death following CO inhalation. Hypothermia may be applicable to treat patients after CO inhalation.

Abstract
OBJECTIVE To detect clinical factors and biomarkers which affect a new grading system for ovarian epithelial cancer that was proposed by Shimizu et al. and to analyze the impact of those factors on malignant behaviors of the tumor. METHODS Review and scoring of specimens of paraffin embedded tissues of epithelial ovarian cancer were carried out according to the new universal grading system in 110 women who underwent initial treatments including the primary operation in our university hospital between January 1990 and June 1999. As biomarkers, expression of Bcl-2, Bax, Bcl-X, and the accumulation of P53 protein were also studied immunohistochemically. RESULTS This grading system functioned as a prognostic indicator. Five-year survivals of the patients was 77.6, 36.3, and 17.4%, for Grade 1, Grade 2, and Grade 3, respectively. The grade was also correlated with clinical stages, histologic subtypes, operative completeness, para-aortic lymph nodes metastasis, and the expression of Bax protein, with univariate analysis. Multivariate analysis revealed histological subtypes and para-aortic lymph nodes metastasis to be important factors which affected the grading system. CONCLUSION These results demonstrate that the new universal grading system is useful, and that this grading system might reflect potential of metastasis or dissemination of the ovarian cancer.

Abstract
Recently, cholesterol hydroperoxides have been shown to be sensitive pathogenic markers of reactive oxygen species (ROS)-mediated damage though they have never been measured in heart tissue. We hypothesized that cholesterol hydroperoxides and oxysterols, putative cardiotoxic products of cholesterol oxidation, are elevated in the hearts of alcoholics as a consequence of ROS-mediated reactions. To test this, we measured 7alpha- and 7beta-hydroperoxycholest-5-en-3beta-ol (7alpha-OOH and 7beta-OOH) by HPLC with postcolumn chemiluminescence as well as 7alpha- and 7beta-hydroxycholesterol (7alpha-OH and 7beta-OH) and 3beta-hydroxycholest-5-en-7-one (also termed 7-ketocholesterol; 7-keto) by HPLC-UV in cardiac muscle of alcohol-fed rats. Alcohol feeding was carried out using a pair-feeding protocol with 35% of total dietary energy as ethanol; controls were pair-fed isocaloric glucose. After 6-7 wk treatment with alcohol, heart 7alpha-OOH, 7beta-OOH and 7beta-OH were significantly greater than in controls. Levels of heart phospholipid 16:0 and 18:1 were lower than in controls, while 18:0 and 18:2 were greater. This is the first report of the presence of 7alpha-OOH, 7beta-OOH and 7alpha-OH in cardiac tissue. The elevations in 7alpha-OOH and 7beta-OOH as well as 7beta-OH are evidence of increased oxidative stress and possible membrane changes. Alterations in the proportions of 16:0, 18:1, 18:2 and 18:0 in heart phospholipids provide further evidence of an altered membrane domain.

Abstract
This report describes the discovery of two new virulence plasmid types from a crossbred foal with Rhodococcus equi pneumonia in Kumamoto died with severe R. equi pneumonia and ulcerative enteritis. R. equi was isolated in large numbers and isolates from the foal were investigated for the presence of virulence-associated 15-17 kDa antigens (VapA) by colony blotting, using the monoclonal antibody 10G5, and by gene coding for VapA by PCR. Plasmid DNAs extracted from the isolates were digested with restriction endonucleases BamHI, EcoRI, EcoT22I, and HindIII. The digestion patterns that resulted divided the plasmids of these isolates into two closely related types. The digestion patterns were then compared with eight representative virulence plasmid types (85 kb types I, II, III and IV, 87 kb types I and II, 90 kb types I and II), which have already been reported. None of the EcoRI and EcoT22I digestion patterns of the eight representative plasmids matched those of the two plasmid types. We tentatively designated these new plasmid types as 90 kb type III and type IV, since HindIII and BamHI digestion patterns of the two plasmid types were identical with those of a 90 kb type I plasmid. This study, demonstrated that there are at least 10 distinct but closely related plasmids present in isolates from horses in the world.

Abstract
OBJECTIVE To evaluate the expression of mRNA of vascular endothelial growth factor (VEGF), its receptors Flt-1 and KDR/Flk-1, and Ets-1 in human corpora lutea. DESIGN Prospective laboratory study. SETTING University hospital in Japan. PATIENT(S) Women with regular menstrual cycles who underwent hysterectomy. INTERVENTION(S) Fifteen corpora lutea were obtained during hysterectomy (5 in the early luteal phase, 5 in the mid-luteal phase, and 5 in the late luteal phase). MAIN OUTCOME MEASURE(S) Expression of VEGF, Flt-1, KDR/Flk-1, and Ets-1 in human corpora lutea on northern blot analysis or immunohistochemistry. RESULT(S) Human corpora lutea in early luteal phase and mid-luteal phase had high VEGF mRNA expression. Expression of VEGF mRNA was significantly reduced in the late luteal phase. Immunohistochemistry showed that VEGF protein was expressed mainly in granulosa lutein cells and faintly in thecal lutein cells. Staining of VEGF protein was decreased in human corpora lutea in the late luteal phase. Expression of Flt-1 and KDR/Flk-1 mRNA was increased in the early luteal phase and mid-luteal phase and decreased in the late luteal phase. Immunohistochemistry showed that Flt-1 and KDR/Flk-1 proteins were expressed mainly in granulosa lutein cells and faintly in thecal lutein cells and endothelial cells in the early luteal phase and mid-luteal phase; their protein staining was reduced in the late luteal phase. Expression of Ets-1 mRNA changed similarly to VEGF and its receptor mRNA in human corpora lutea during the luteal phase. CONCLUSION(S) Levels of mRNA of VEGF and its receptors Flt-1 and KDR/Flk-1 in human luteal cells may be related to luteal function.

Abstract
To examine whether and at which stage of endometrial carcinogenesis decreased connexin expression occurs, we investigated changes in the expression of the gap junction proteins, connexin 26 (Cx26), Cx32 and Cx43, in human endometrial hyperplasia and cancer samples. Forty-eight endometrial tissue samples (15 endometrial hyperplasias and 33 endometrial cancers) were subjected to immunofluorescence and RT-PCR analysis. In endometrial hyperplasia, Cx26 was aberrantly expressed in all samples as revealed immunohistochemically. There was weak or negative expression in 12 samples (80.0%) and diffuse expression in cytoplasm in 3 samples (20.0%). Cx32 expression in those samples was similar to that of Cx26; there was weak or negative expression in 11 samples (73.3%) and diffuse expression in 4 samples (26.7%). In endometrial cancer, Cx26 was expressed weakly or negatively in 25 samples (75.8%), diffusely in 6 samples (18.2%) and normally in 2 samples (6.1%), while Cx32 was expressed weakly or negatively in 26 samples (78.8%), diffusely in 5 samples (15.2%) and normally in 2 samples (6.1%). It was confirmed that weak staining of Cx26 and Cx32 was due to poor expression of their mRNA. All samples showed weak Cx43 protein expression as revealed by immunohistochemical analysis. In the majority of samples, concomitant expression levels of Cx26 and Cx32 protein were observed, confirming our long-term hypothesis that Cx26 and Cx32 are both abnormally regulated in a coordinated fashion in the endometrium. Our results indicate that during endometrial carcinogenesis, loss of gap junctional intercellular communication (GJIC) may occur due to the suppressed expression and the aberrant localization of connexin at relatively early stages.

Abstract
The patient was a 59-year-old woman with recurrent ovarian cancer. A CT scan of the abdomen showed enlargement of abdominal para-aortic lymph nodes (PAN) after the primary operation and 8 cycles of the combination chemotherapy with paclitaxel (TXL) and carboplatinum (CBDCA). As a second line chemotherapy for the patient, weekly administration of TXL (60 mg/m2/week x 3 weeks) was given. The toxicity was acceptable and less pronounced than with the standard TXL + CBDCA therapy. Peak blood TXL concentration, about 90 ng/ml, was achieved 4 hours after the administration of TXL. The blood TXL concentration was below the detectable limit 48 h after the administration of TXL. An almost 50% shrinkage in the size of the PAN was obtained after 2 cycles of treatment. Good QOL is being maintained without any repeated aggravation of the tumor.

Abstract
Beta-casein-like protein (BCLP) is a putative protein on cervical cancer and exhibits immunological characteristics similar to those of bovine beta-casein. We evaluated if BCLP mRNA detection in the blood is useful in gynecologic malignancies. We examined 30 patients with uterine cancer, nine cultured cancer cell lines and 26 healthy women volunteers. From these study populations and samples, total RNA was obtained. Reverse transcriptase-PCR (RT-PCR) of BCLP was performed on each sample. Eighteen (60.0%) patients and 4 (15.4%) volunteers were positive for BCLP mRNA. The RT-PCR reached sensitivity and specificity of 60.0% and 84.6%, respectively. Of eight patients having diagnosed recurrence, 7 (87.5%) were positive for BCLP mRNA. In patients with recurrence, sensitivity and specificity were 87.5% and 50%, respectively. The expression of mRNA showed a correlation with recurrence, but no correlation with metastasis or histological type. BCLP was specifically expressed in cancer cells and might be an aid in clinical diagnosis.

Abstract
Monoclonal antibody (MAb) 1C5 reacts with 87% of uterine cervical adenocarcinoma and bovine beta -casein, but not with squamous cell carcinoma. To clarify the characteristics of the antigen (beta-casein-like protein; BCLP) recognized by MAb 1C5, molecular cloning was performed using 5' rapid amplification of the cDNA ends (5' RACE) and the oligo-capping method. The protein predicted from the cDNA consisting of 937 nucleotides comprises 222 amino acids. The BCLP gene and deduced amino acid sequences were novel and showed no similarity to known cancer-associated genes in the database. Northern blot analysis showed that a 1.1 kb transcript was ubiquitously expressed in cancer cell lines and was predominantly expressed in uterine cervical adenocarcinoma. To clarify the function of BCLP, BCLP cDNA was transfected into L929 cells, resulting in a significant increase in cell area, a downregulation of cell growth rate and a decrease in cell attachment. We conclude that BCLP might be associated with cell morphology and a regulation of growth pattern of tumor.

Abstract
The endometrium is a uniquely dynamic tissue in that it undergoes monthly cycles of proliferation and secretory activity, and is regulated by ovarian steroid hormones. In this study, we focused on retinoic acid receptors (RAR and RXR) which are ligand-dependent transcription factors belonging to the large family of steroid hormones and are expected to affect to cell growth and differentiation in the endometrium. We analysed the expression and subcellular localization of the RA receptors in 57 samples of human endometrium by immunohistochemistry and Western blotting. In the nuclei of the endometrial epithelium, the RA receptors were expressed strongly in the proliferative phase. However, RAR were drastically reduced in the epithelial nuclei during the secretory phase in association with changes in serum oestradiol and in the expression of the oestrogen receptor. The expression of RXR was localized in the epithelial nuclei throughout the menstrual cycle. Confocal laser scanning microscopical observation clearly showed the difference in the localization between RAR and RXR in the secretory phase. Furthermore the findings of immuno-electron microscopy showed pooled RAR around the rough endoplasmic reticulum, suggesting that transport of these receptors to the nuclei is inhibited. These findings suggest that RAR and RXR work mainly in the proliferative phase and that in the endometrium RXR may play a different role to RAR during the secretory phase.

Abstract
We have previously shown that the subcellular localization of beta-catenin changes according to the cell proliferation status of the human endometrium, suggesting a role of intercellular transduction in cell growth control in human endometrium not only in the physiological but also in the carcinogenic condition. To further study the possible role of heat shock proteins (HSPs) in growth control, we immunohistochemically analyzed 92 endometrial samples, 30 of normal endometrium, 20 of endometrial hyperplasia and 42 of endometrial cancer, for expression of HSP27, HSP70, HSP90, estrogen receptor (ER) and progesterone receptor. HSP27 and HSP90 were detected in endometrial epithelium strongly in the proliferative phase and weakly in the secretory phase during the menstrual cycle according to the serum estradiol level. However, they were over-expressed in endometrial hyperplasia, especially HSP27. In endometrial cancer, HSP27 expression was heterogenic among the glands and lower than that in the proliferative phase and endometrial hyperplasia. HSP27 over-expression was also observed in samples including endometrial cancer and associated hyperplasia. Results of Western blotting followed those of immunohistochemistry. HSP70 was not changed during the menstrual cycle, as HSP27 and HSP90 were, and was rather stably expressed in endometrial hyperplasia and cancer. Our results suggest that HSP27 and HSP90 contribute to cell proliferation in endometrial epithelium and that over-expression of HSP27 in endometrial hyperplasia occurs as a result of the activated condition of ER, though in cancer it decreases according to the loss of function of ER.

Abstract
OBJECTIVE To compare maternal serum levels of two markers of collagen synthesis, procollagen I carboxy-terminal peptide (PICP) and procollagen III amino-terminal peptide (PIIINP), in patients with pre-eclampsia and in controls. METHODS PICP and PIIINP were measured by radioimmunoassay in maternal serum samples from patients diagnosed with pre-eclampsia at 32 weeks' gestation or later and in controls from the same period of gestation. For PICP, 37 cases and 36 controls were studied; for PIIINP, 12 cases and 19 controls were studied. RESULTS Both PICP and PIIINP levels were significantly elevated in patients with pre-eclampsia. PICP and PIIINP levels were, on average, 20% and 80% higher than in controls, respectively. CONCLUSIONS These results are in agreement with previous findings that maternal serum levels of PICP and PIIINP are mildly elevated in patients with pre-eclampsia. These markers are unlikely to be useful in the prediction of pre-eclampsia.

Abstract
A 69-year-old type 2 diabetic man was admitted due to diabetic gangrane. He had a history of subtotal gastrectomy. During hospitalization, he was treated with regular insulin and 300 mg/day of acarbose. He developed a low grade fever, cough and nasal discharge, and was given a compound "cold" remedy with anticholenergic properties. The next day, he suffered from a paralytic ileus. Oral intake and acarbose were withheld and the ileus spontaneously resolved after 2 days. These finding indicate the possibility that the ileus was triggered by drugs with anticholinergic properties in this elderly diabetic patient treated with alpha-glucosidase inhibitors.

Abstract
Polycystic ovary syndrome (PCOS) is characterized by cystogenesis; however, the cause of this cystogenesis is unknown. At ovulation, preovulatory collagenolytic activities in the ovarian follicles increase and various proteinases are needed to degrade the tissues surrounding the follicles. To clarify the roles of enzymes in collagen degradation of the follicular wall of polycystic ovary (PCO) in relation to the cystogenesis, we examined expression of lysyl oxidase (LOX), which initiates cross-link formation of the collagen and elastin in the extracellular matrix, and expression of matrix metalloproteinases (MMPs) in ovaries of model rats with PCO induced by dehydroepiandrosterone (DHEA) compared with MMP expression in control rats. DHEA treatment increased LOX mRNA expression to more than three times the control value (P: < 0.01). MMP-2 mRNA expression in control rats was threefold greater than that in the DHEA-induced group (P: < 0.05). Expression of both latent and active forms of MMP-2 in controls was more than twice that in the DHEA-induced group (P: < 0.05) as shown by Western blotting, and expression of the active form of MMP-2 was also twice as high in the controls as in the DHEA-treated group (P: < 0.05) as shown by zymography. Our results suggest that depression of MMP-2 activity and increased LOX expression may be one of the causes of the cystogenesis of PCO.

Abstract
Increased vascular sensitivity to vasoconstrictors, such as angiotensin II and epinephrine, is observed in preeclampsia (PE). Recently, it was suggested that abnormal endothelial function might contribute to the pathophysiologic changes in PE. We investigated vasoconstrictor (angiotensin II and epinephrine)-induced endothelin-1 (ET-1) release from human umbilical vein endothelial cells incubated with sera from women with PE compared with normotensive pregnant and nonpregnant women. Moreover, inositol 1,4,5-trisphosphate production and endothelin-converting enzyme (ECE) expression in human umbilical vein endothelial cells were also evaluated. There were no significant differences in ET-1 release without vasoconstrictors among the three groups (nonpregnant, normotensive pregnant, and PE). No significant differences in basal inositol 1,4,5-trisphosphate production and ECE expression without vasoconstrictors were detected among the three groups. Vasoconstrictor-induced ET-1 release was significantly increased by PE sera. No significant difference was detected in vasoconstrictor-induced inositol 1,4,5-trisphosphate production among the three groups. However, ECE expression after incubation with vasoconstrictor was significantly increased by PE sera. Our results suggest that ET-1 release from endothelial cells may contribute to the increased vascular sensitivity to vasoconstrictors observed in PE, and that vasoconstrictor-induced ET-1 release may be related to enhanced ECE expression.

Abstract
OBJECTIVE To review 10,016 cases of total vaginal hysterectomy (TVH) performed in our department by a method without ligation of the paracervical ligaments. METHODS From 1955 to 1997, a total of 10,016 TVHs without ligation of the paracervical ligaments were performed at the Department of Obstetrics and Gynecology, Sapporo Medical University Hospital. RESULTS Of all 22,509 gynecological operations, 44.5% were TVHs, and 8.7% were total abdominal hysterectomies (TAHs). The operative time of our TVHs ranged from 31-60 minutes in 44.1% of the cases, and from 61-90 minutes in 35.3% of the cases. Blood loss was less than 300 ml in 85% of the cases. Abdominal conversion from the vaginal approach occurred in 110 cases (1%). Operative complications also occurred only in 0.7% (69) of the cases. CONCLUSION TVH without ligation of the paracervical ligaments is a safe and convenient method that has very few complications and that can be utilized by many gynecologists.

Abstract
A case of uterine endometrial carcinoma 15 months post-partum, who did have none of typical risk factors of uterine endometrial carcinoma, is presented. The occurrence of post-partum uterine endometrial carcinoma is extremely rare condition probably due to anti-carcinogenic effects of progesterone. Progesterone refractory cells in the uterine endometrium, which could be an origin of the endometrial carcinoma, might have existed.

Abstract
OBJECTIVE To report the results of prenatal triple marker screening on a population of Japanese pregnant women. METHODS From April 1994 through March 1999, a total of 32,925 native Japanese women with singleton pregnancies requested a triple marker-screening test. Multiples of the median values for 3 markers and individual risks for each patient were calculated following adjustment for the Japanese weight correction factor. The risk cut-off values used for Down syndrome (T21), open spina bifida (OSB) and trisomy 18 (T18) were 1: 295, 1: 290, and 1: 100, respectively. Follow-up information was collected postpartum and statistically analyzed. RESULTS Detection rates (DR) of T21 for women less than 35 years, over 35 years and overall were 58, 94, and 83%, respectively. DR of T18 for women less than 35 years, over 35 years and overall were 75, 79, and 79%, respectively. DR of open neural tube defects (ONTD) was 100%. CONCLUSIONS The first cumulative data of an intervention program and prospective follow-up studies in Japan have proven to be similar to other published reports. Individual risk values were calculated for each pregnancy for T21, T18 and ONTD. This screening program is more effective than age-dependent screening for detecting T21, T18 and ONTD pregnancies.

Abstract
BACKGROUND Malignant melanoma in the vagina is very rare, but its diagnosis is usually easy if a melanin pigment is present. With cytodiagnosis, however, it is difficult to differentiate amelanotic melanoma or scantily pigmented melanoma from other conditions. In the present case, monoclonal antibody HMB-45, the efficacy of which has been established in histologic studies, was used in the cytodiagnosis of amelanotic melanoma in the vagina. CASE A woman, aged 78 years, presented with a brownish, nodular tumor, diameter 3 cm, in the vagina. Scraping smears with Papanicolaou staining showed nonepithelial malignant cells without granules suggesting melanin. Smears stained with HMB-45 showed positive immunoreactivity. The diagnosis underwent histologic confirmation of amelanotic melanoma on the initial biopsy. CONCLUSION Cytodiagnosis was made with HMB-45, which proved very effective in the differential cytodiagnosis of amelanotic melanoma and scantily pigmented melanoma, particularly because it obviated the need for tissue invasion.

Abstract
OBJECTIVES The aim of our study was to determine the important molecules responsible for the invasive activity of ovarian cancer cells. METHODS We compared the biological characteristics, that is, growth rate, motility, and invasive activity, of five ovarian cancer cell lines with the gene expression of various matrix proteases (matrix metalloproteinase-1 [MMP-1], MMP-2, MMP-9, membrane-type MMP type 1 [MT1-MMP], MT2-MMP, MT3-MMP, urokinase plasminogen activator [uPA]), their inhibitors (tissue inhibitor of metalloproteinase type 1 [TIMP-1], TIMP-2, plasminogen activator inhibitor type 1, [PAI-1], and PAI-2), and the potential transcriptional regulators E1AF and Ets-1. RESULTS There was no clear correlation in the growth rate, motility, and invasion, suggesting that there are independent properties for malignant potential in ovarian cancer cells. However, HTBOA, a poorly differentiated cancer cell line, exhibited highly invasive activity, rapid growth, and increased motility. This cell line also expressed both Ets transcriptional factors, E1AF and Ets-1, and many matrix-degrading enzymes. Three cell lines that expressed E1AF showed rapid cell growth. The highly invasive cell lines, HTBOA and HTOA (well-differentiated serous cystadenocarcinoma), produced either MMP-2 or MMP-1, and both cell lines expressed MT1-MMP and uPA. Furthermore, the active forms of pro-MMP-2 and pro-MMP-1 were detected in HTBOA and HTOA by zymography. CONCLUSION We conclude that activated MMP-2 and MMP-1 are important in the invasive activity of these ovarian cancer cells.

Abstract
The regulatory mechanism of the recognition and cytotoxicity by natural killer (NK) cells in placental tissue remains unclarified. Previous reports indicated that monoclonal antibody Cho-1-defined molecule (Cho-1 molecule) may act as the negative regulator in the cytotoxicity by human NK cells. The Cho-1 molecule is composed of non-covalently associated cell surface molecules of approximately 200 kDa and 40 kDa. In the present study we analyzed the expression of this novel molecule in extravillous cytotrophoblast cells, which are presumed to be exposed to the cytotoxic action by maternal NK cells, from clinical cases of successful pregnancy and spontaneous abortion. By using monoclonal antibody Cho-1, our immunohistochemical data indicated that the Cho-1 molecule is clearly expressed in the cytotrophoblast cells of the early phase of successful pregnancy, but only weakly expressed in those from spontaneous abortion. The cytotrophoblast cells in the late phase (9-10 months) of pregnancy also expressed this molecule. Fluorescence-activated cell sorter analysis also showed that it is expressed on the cytotrophoblast cell surface of successful pregnancy but not on that of spontaneous abortion, suggesting that Cho-1 antigen may act as a negative regulator of the cytotoxicity by NK cells in successful pregnancy of the fetus.
