Abstract
Stroke incidence and cognitive decline are related to progression of arteriosclerosis in intracranial DWLs. However, the relationships between DWLs and factors associated with their progression, including CKD, have not been fully elucidated using longitudinal MRI. Of 291 individuals (184 males, 107 females; age 66.9 ± 6.1 years) who had voluntarily participated in a hospital-based health check-up and underwent repeated brain MRI scans in 2003 and 2008, 273 were evaluated in this study. The DWL group included those having DWL without progression, and the DWL progression (DWLP) group included those having an increase in grade number according to the Fazekas classification. Unimpaired age-matched subjects with no brain MRI abnormalities constituted Group C. The Mini-Mental State Examination (MMSE) and verbal fluency tasks were used for objective cognitive evaluations according to the MR evaluation schedule in 2008. Associations between DWLs and vascular risk factors were examined. DWLP occurred in 9.2% of subjects. Compared to Group C subjects, DWL and DWLP group subjects had high odds ratios (ORs) for hypertension (HT) (2.23 and 2.92, respectively) and CKD (1.40 and 2.41, respectively). After adjustment for potential confounders, the ORs of CKD for DWLs remained significant (1.13 and 1.43, p<0.05). DWLs and DWLP were associated with low cognitive scale scores and increased CKD. In conclusion, CKD was associated with DWLs and DWLP as an independent risk factor and a lower level of cognitive function 5 years after CKD was identified. Successful CKD therapy may be expected to prevent DWLP.

Abstract
OBJECTIVE To elucidate the relationship between embryo grade and ART outcomes and determine how to decrease multiple pregnancy rates by assigning patients to single embryo transfer (SET) instead of dual embryo transfer (DET) according to embryo grade and/or availability. DESIGN Retrospective medical record review. SETTING IVF fertility center. PATIENTS 247 women undergoing day 5 DET after in vitro fertilization or intracytoplasmic sperm injection treatment. METHODS We retrospectively investigated embryo grade and outcomes on day 5 DET and calculated theoretical multiple pregnancy rates by assigning patients to SET instead of DET according to a combination of embryo grades and availability. MAIN OUTCOMES MEASURES Implantation, pregnancy, multiple pregnancy, expected pregnancy and expected multiple pregnancy rates. RESULTS Embryo grade affects implantation rates so that embryo transfer of at least one embryo with grade > or = 3BB resulted in high multiple pregnancy rates as well as high pregnancy rates. By performing DET, the clinical pregnancy rate was 39.9% with a multiple pregnancy rate of 33.3%; however, had SET been performed with an embryo graded 3BB or better, theoretical calculated pregnancy rates would have dropped to 35.8% but with a multiple pregnancy rate of 7.2%. CONCLUSIONS Our model showed that cases having at least one embryo with grade > or = 3BB might serve as suitable candidates for SET.

Abstract
Three patients with Alzheimer's disease of mild type received long-term treatment with THA at doses between 40 mg to 160 mg daily. This study describes the effects of THA on EEG, seen during long-term and high dose treatments. After short-term treatment, the changes of the mean frequency in the temporal and parieto-occipital regions varied between patients, but in the frontal region a significant increase of the mean frequency was seen in all patients. The EEG improvement seen in the frontal region was more significant than that for the other regions at low dose of THA (80 mg). During long-term treatment, we observed different types of EEG changes. The early improvement seen in two patients was temporary and reverted to the pre-treatment value. In a third patient who did not show marked improvement after short-term treatment, an improvement was seen in all regions after longer treatment. Treatment with high doses of THA (120 mg or 160 mg) induced a marked increase in the mean frequency not only in the frontal region but also in the temporal and parieto-occipital regions. Higher doses of THA seem to affect larger areas of the brain than lower doses of THA.

Abstract
We report a case of malignant pericardial effusion after lung cancer surgery treated with thoracoscopic pericardial fenestration. The patient was admitted to our hospital because of dyspnea. Computed tomography (CT) and ultrasound cardiography (UCG) revealed cardiac tamponade which was diagnosed as carcinomatous pericarditis by cytology. We attempted to inject 25 mg of cisplatin (CDDP) into the pericardial space twice. The response of the treatment was unexpectedly poor for the patient. The thoracoscopic pericardial fenestration was performed and the patient was discharged without a drainage tube on the 17th postoperative day. Malignant pericardial effusion is a common complication of advanced cancers and is often associated with significant morbidity. Thoracoscopic pericardial fenestration appears to be a safe, effective and minimally invasive treatment for patients with malignant pericardial effusion. This surgery might also have a favorable effect on the improvement of the quality of life for patients with malignant pericardial effusion resistant to chemotherapy.

Abstract
OBJECTIVE To determine whether obesity is associated with surgical outcome in Japanese patients undergoing retroperitoneoscopic radical nephrectomy (RRN). PATIENTS AND METHODS Between November 1999 and March 2005, we performed 98 RRN procedures for patients with renal cell carcinoma. Patients with a body mass index (BMI) of 25.0 or more were defined as obese (group A, n=33) and those with a BMI of <25.0 were defined as non-obese (group B, n=65), in accordance with the criteria of the Japan Society for the Study of Obesity. Patient background, degree of surgical invasiveness, and period of convalescence were compared between groups A and B. RESULTS No statistically significant differences were observed between the groups in terms of age, gender, tumor laterality, tumor size, and time until resumption of oral intake and ambulation. However group A had a significantly longer insufflation time (172.1 vs. 137.4 min), greater blood loss (195.3 vs. 48.4 ml) and higher renal specimen weight (440.0 vs. 306.0 g) than group B. CONCLUSION Obesity is not a factor that affects patient eligibility for RRN, but is a risk factor for longer insufflation time and greater blood loss.

Abstract
The role of resistin in human biology remains uncertain. We measured serum resistin levels in Japanese patients with (n=111) and without (n=98) type 2 diabetes mellitus and investigated the significance of this hormone in the pathophysiology of diabetes. The levels of serum adiponectin and leptin were also measured. Resistin levels were increased significantly in patients with type 2 diabetes compared with non-diabetic subjects (24.7+/-2.6 vs. 15.0+/-1.2 ng/ml, p=0.0013). However, there was no correlation in either patient group between serum resistin levels and markers of insulin resistance, obesity or hyperlipidaemia. These results were in direct contrast to the data of leptin or adiponectin, both of which were closely related to these clinical markers of diabetes. Multivariate regression analysis on the combined data of the two groups demonstrated that the presence of diabetes and HDL cholesterol levels were significant predictors of serum resistin levels (diabetes: beta=0.159, p=0.035; HDL: beta=-0.172, p=0.039). No correlation was observed between C-reactive protein and resistin adjusted for BMI. Taken together, these findings demonstrate that serum resistin levels are increased in patients with type 2 diabetes, but this increase is not linked to markers of insulin resistance or adiposity. Further studies are necessary to elucidate the significance of serum resistin concentration in human pathophysiology.

Abstract
Vascular dementia (VaD) differs from Alzheimer's disease (AD) in larger fluctuations of cognitive impairment, hypothetically because of deteriorated vigilance control. Vigilance levels are reflected by locations of EEG sources. Transition from alertness to sleep might be particularly sensitive to degradations of vigilance control. Twelve AD and 12 VaD patients (medication free, mean age 75.6 and 77.6 years, respectively, difference = n.s.), and 12 healthy elderly subjects (mean age 70.6 years), who served as controls, were studied (each group comprised 2 males and 10 females). A twenty-one-channel EEG was recorded from full alertness to the onset of sleep stage 2. Dipole source modeling, based on Fast Fourier Transform dipole approximation, yielded 3D source localizations in 7 EEG frequency bands. For each brain axis, means of source location differences between successive 20-second periods were calculated (fluctuation magnitude). EEG band-wise MANCOVAs (3 brain axes, 3 subject groups, covariate: age) showed differences in fluctuation magnitude between groups in the 10.5- to 12-Hz alpha(2) frequency band (p=0.0066). Post hoc ANCOVAs for the axes (3 subject groups, covariate: age) were significant on the superior-inferior axis: VaD patients had higher fluctuations than AD patients and controls, without significant difference between the latter two. Thus, larger source fluctuations in VaD might reflect the patients' decreased vigilance control, accounting for their increased fluctuations of cognitive impairment.

Abstract
Large cell neuroendocrine carcinoma (LCNEC) is a rare type of lung cancer and it has the least favorable prognosis. We describe our experience with a patient in whom LCNEC was diagnosed. A 65-year-old man who was pointed out abnormal shadow on a chest X-ray film in the health screening was admitted to the hospital. Chest X-ray film and computed tomography (CT) scan showed a 4 x 3 cm mass in the left-S2. Poorly differentiated adenocarcinoma of the left lung was suspected based on CT guided cytology. An upper lobectomy of the left lung and dessection of the mediastinal lymph nodes were performed. This tumor showed light microscopic and immunohistochemical evidences of neuroendocrine differentiation. Further it showed positive responses in neuronspecific enolase (NSE), synaptophysin, and chromogranin-A stainings. Pathological diagnosis was stage IB (pT2N0M0) LCNEC. There have been no findings of tumor recurrence 22 months after the operation.

Abstract
In order to elucidate brain mechanisms that contribute to the increased tendency for vigilance dysregulation in the elderly, we examined the spatial organization of brain electric activity [electroencephalogram (EEG)] during decreasing vigilance from alertness to onset of sleep stage 2, comparing 7 old and 10 younger, healthy subjects (60-79 and 18-41 years old, respectively). Two features were analyzed: (1) change of location of the brain electric source gravity centers of the EEG frequency bands, and (2) magnitude of fluctuation of these locations over time. Multichannel EEG was analyzed into source gravity center localizations for seven EEG frequency bands, using fast Fourier transform (FFT) Dipole Approximation (first principal component-single source modeling in the frequency domain). Multivariate analysis of covariance (MANCOVA) showed: source localizations were more anterior in old than younger subjects for beta-1 and more superior for all three beta bands; from alertness to sleep, delta and theta EEG sources (inhibitory activity) changed to more posterior and superior areas, and alpha-1 and -2 (routine activity) and beta-1 and -2 sources (excitatory activity) towards anterior and superior areas. Fluctuations of the source locations of delta and beta-2 were larger on the superior--inferior axis, and of beta-2 smaller on the left-right axis in the old than younger subjects. The results suggest functional specifications (inhibitory, routine, excitatory) of cortical positron emission tomography (PET) changes reported in sleep. In sum, aging exhibits changes in spatial organization of EEG-generating neuronal assemblies; during the transition wakefulness-to-sleep, aging affects the spatial-temporal dynamics of this organization. The latter is suggested to contribute to the increased risk for consciousness disturbances in the elderly.

Abstract
We performed surgery for distal arch aneurysm in 22 patients; through a mediansternotomy in 11 patients (group M), and through a left thoracotomy approach in 11 patients (group L). If the distal position of an aneurysm was located at the pulmonary hilus without severe calcification of the ascending aorta, the mediansternotomy approach was chosen, whereas if we suspected that distal anastomosis would be difficult due to severe calcification of the descending aorta or aortic dissection type B, the left thoracotomy approach was selected. The mean cardiopulmonary bypass time (min.) was 229 +/- 56 in group M and 225 +/- 47 in group L, the mean circulation arrest time (min.) was 39 +/- 19 in group M and 31 +/- 5 in group L, and the mean lowest temperature (degree C) was 22 +/- 1 in group M and 20 +/- 2 in group L. No severe cerebral or cardiac complications developed in any patients. The hospital mortality was 9% (1/11) in group M and 9% (1/11) in group L. Following discharge, 8 (73%) patients from group M and 9 (92%) from group L resumed a normal lifestyle. There were no significant differences between the 2 groups and the operative results of both approaches proved satisfactory. Therefore our indications for each surgical approach to treat distal arch aneurysm seemed appropriate.

Abstract
Multicystic dysplastic kidneys (MCDK) and obstructive renal dysplasia (ORD) are two different phenotypes of dysplasia commonly associated with urinary tract obstruction. However, the mechanisms whereby obstruction in the developing kidney leads to each dysplasia are unknown. In the present study, 16 fetal MCDKs and 3 fetal ORDs (18-35 weeks of gestation) were analyzed with light microscopy, point-counting morphometry, immunohistochemistry with a podocyte marker, and scanning electron microscopy. Additionally, reconstructions of dysplastic nephrons were done via serial section analysis. Early stages of MCDK and ORD similarly revealed numerous cyst formations, predominantly in the subcapsular nephrogenic zone. Occasionally, glomerular tuft remnants with mature podocyte phenotypes were observed in cysts, suggesting the acquisition of filtration. Three dimensionally, basic nephron structures were installed in the cystic nephrons, namely the macula densa with a primary loop structure. Cysts developed in the once-induced nephrons due to fluid retention in both MCDK and ORD. In utero urinary tract obstruction may cause urine retention in functioning nephrons and lead to glomerular cysts in the nephrogenic zone. These findings were common to MCDK and ORD, albeit at different sites of obstruction. Expansion of glomerular cysts with tubular dilatation (cysts) disturbs the subsequent nephrogenesis and may contribute to the misdevelopment of fetal kidneys.

Abstract
PURPOSE This study was conducted to clarify the relationship between Bacille de Calmette-Guérin (BCG) inoculation and corticosteroid sensitivity. METHODS Lewis and WKAH rats were inoculated with BCG vaccine weekly beginning at six weeks of age. At 15 weeks, spleen cells were cultured with PHA and betamethasone for 24 hours. RNA was extracted and interleukin-2 gene expression was measured using a real-time PCR method. RESULTS BCG inoculation sensitized Lewis rats, but not WKAH rats, to PPD stimulation. In Lewis rats, IL-2 gene expression increased after BCG inoculation, while betamethasone suppressed IL-2 expression. In WKAH rats, the expression of IL-2 was not affected by repeated BCG inoculations and betamethasone had no effect on BCG-treated rats. CONCLUSION BCG inoculation may affect steroid sensitivity in some strains of rats.

Abstract
Bronchial hyperresponsiveness (BHR) produces the characteristic pathological abnormalities seen in asthma and clearly plays a central role in the pathophysiology of asthma. The presence of BHR has been demonstrated in infants with asthma, as has the possibility of BHR persisting through the childhood period. The level of BHR may not only reflect the state of the airways, as a marker of airway dysfunction, but may also predict the persistent prognosis of the disease. Thus, measurement of BHR may provide important information about the symptoms and lung function in children with asthma. In view of multiple pathophysiological mechanisms, BHR does not seem to have a single cause. Many potential confounding variables, such as age, gender and genetic status, and some environmental factors, such as allergens, infections, and pollutants, could be responsible for the establishment of childhood BHR. There may be differences between the mechanisms that induce transient BHR and the mechanisms that induce persistent BHR. Also, there may be differences between the causes that induce BHR in the infantile period and the causes that maintain persistent BHR during childhood asthma. There is also disagreement as to the most suitable method to measure BHR in children, especially in infants. The assessment of BHR in young children has not been uniformly successful, and measurements of BHR changes over the childhood period (are associated with a number of problems. To resolve these problems, there may be two ways to study childhood BHR. One is to use age-matched specific techniques to clarify the precise BHR in each age group; the other is to use simple techniques that can be performed over the childhood period on a large number of subjects. In studies of infantile respirator, dysfunction the ultimate goal is to establish a simple, noninvasive method by which measurements of respiratory function may be obtained in infants. Further investigations and acceptable methods will be needed to clarify, the mechanisms involved in the establishment of asthma throughout the childhood period.

Abstract
Donepezil was developed in order to overcome the disadvantages of physostigmine and tacrine. Its use is based on the cholinergic hypothesis. Donepezil is a piperidine-based, reversible acetylcholinesterase inhibitor, that is chemically unrelated to other cholinesterase inhibitors. It was developed for the symptomatic treatment of Alzheimer's disease (AD). Donepezil is highly selective for acetylcholinesterase with a significantly lower affinity for butyrylcholinesterase, which is present predominantly in the periphery. Phase I and II clinical trials demonstrated donepezil's favorable pharmacokinetic, pharmacodynamic and safety profile. There is no need to modify the dose of donepezil in the elderly or in patients with renal and hepatic failure. Pivotal phase-III trials in the US, European countries, and Japan showed that donepezil significantly improved cognition and global function in patients with mild to moderate AD. In long-term trials, donepezil maintained cognitive and global function for up to 1 year prior to the resumption of gradual deterioration. Donepezil is generally well tolerated; most of its adverse events are mild, transient and cholinergic in nature. Donepezil produces no clinically significant changes in laboratory parameters, including liver function. The drug is approved for the treatment of mild to moderate Alzheimer's disease, but donepezil therapy does not have to be discontinued if a patient continues to deteriorate. Possible new indications for donepezil in psychiatric and neurologic diseases, other than AD, include dementia with Lewy bodies, brain injury, attention deficit hyperactivity, multiple sclerosis, Down's syndrome, delirium, mood disorders, Huntington's disease and sleep disorders.

Abstract
Proliferative response of peripheral blood mononuclear cells (PBMC) to glutamic acid decarboxylase (GAD), which has been reported in patients with type 1 diabetes, was measured in type 2 diabetes, especially in patients with antibodies to GAD initially diagnosed as having type 2 diabetes (anti-GAD+ type 2 diabetes). We studied 12 patients with type 1 diabetes, 22 with anti-GAD+ type 2 diabetes, 31 with type 2 diabetes who were negative for anti-GAD (anti-GAD+ type 2 diabetes), and 30 healthy control subjects for cellular responses in vitro to GAD. The mean stimulation index (SI) in response to GAD was significantly higher in type 1 diabetes than in anti-GAD+ type 2 diabetes or healthy controls (1.47+/-0.35 vs. 1.11+/-0.35, P<0.05, and 1.06+/-0.07, P<0.05, respectively).

Abstract
OBJECTIVE To assess at what age bronchial hyperresponsiveness (BHR) is acquired in children with asthma. BACKGROUND A relationship between BHR and infantile wheezing diseases has been reported. Infants with a genetic predisposition to atopy are more likely to wheeze with respiratory viral infection or bronchiolitis, and it is suspected that the continued BHR after the first attack of asthma may be induced or triggered by some viral infections. Also, recent studies have reported the existence of atopic and BHR-related genes. However, whether BHR is congenital or acquired after asthma attacks, and when BHR in children with asthma is established or acquired remain unclear. METHODS We performed methacholine inhalation challenge using a transcutaneous oxygen pressure (tcPO(2)) monitoring system in 205 children without asthma from 6 months to 6 years of age. During follow-up, 18 of these participants were diagnosed with asthma (group N-A). This group and 15 age-matched children without asthma (group N-N) were tested twice using methacholine inhalation challenge. For comparison, 39 age-matched atopic-type asthmatic children (group A-A) were also given the inhalation challenge twice. Methacholine inhalation challenge using a tcPO(2) monitoring system was performed while the participants were asleep in the supine position. Sequential doses of inhaled methacholine delivered by oxygen mask were doubled until a 10% decrease in tcPO(2) from the baseline was reached. The cumulative dose of methacholine at the inflection point of tcPO(2) (minimal dose of methacholine [Dmin]-PO(2)) was considered to represent BHR. RESULTS In groups N-N and A-A, there was no difference in Dmin-PO(2) between the first and second challenge. However, the Dmin-PO(2) in group N-A significantly decreased from the first challenge to the second challenge. There was no significant difference between the Dmin-PO(2) in group N-N and the first Dmin-PO(2) in group N-A; or between the Dmin-PO(2) in group A-A and the second Dmin-PO(2) in group N-A. CONCLUSIONS These data suggest that BHR in many infants with asthma is acquired after several asthma attacks.bronchial hyperresponsiveness, childhood asthma, methacholine inhalation challenge, transcutaneous oxygen pressure.

Abstract
A method for demonstrating whether a gene of Staphylococcus aureus is essential for growth in a rich medium is described. We have used this method to determine whether the murE gene, which encodes the UDP-N-acetylmuramyl tripeptide synthetase required for peptidoglycan synthesis, is essential for growth in S. aureus. In this study, strain CYL368 was constructed from S. aureus RN4220 by placing the murE gene in the chromosome under the control of the spac promoter (a hybrid promoter of the Escherichia coli lac operator and the Bacillus subtilis SPO1 phage promoter). To regulate the murE gene in CYL368, the E. coli lacI gene was expressed from the B. licheniformis penicillinase gene (pcn) promoter in plasmid pMJ8426. Strain CYL368(pMJ8426) grew normally in the presence of isopropyl-beta-d-thiogalactopyranoside but could not grow in the absence of the inducer. These results indicate that the murE gene expressed from the spac promoter in CYL368(pMJ8426) is needed for bacterial growth. We concluded that murE is an essential gene of S. aureus.

Abstract
The zona pellucida (ZP) of mammalian oocytes forms an extracellular matrix composed of three major glycoproteins and plays an important role in sperm-zona interactions. As ZP had a strong organ-specific but species-cross-reactive antigenicity and passive or active immunization with ZP antigens could impair fertilization, the possibility of developing a immunocontraceptive vaccine has been extensively studied. Studies on active immunization with porcine ZP (pZP) that contain B cell epitopes and T cell epitopes demonstrated that a temporary infertility could be induced along with the elevation of antibody titers, but it was always associated with ovarian failure. This could be due to the oophoritis by activation of pathogenic T cell immunity. It is the general consideration that any adverse effects by vaccination should be avoided for an immunocontraception. From this point of view, the analysis of B cell epitopes of pZP protein would be helpful for construction of a safe immunocontraceptive vaccine with zona antigens. We determined the amino acid sequence of the B epitope in the pZP1 protein by using a monoclonal antibody (MAb-5H4) that possesses a fertilization blocking ability. In addition, antiserum raised to the epitope sequence was revealed to block in vitro fertilization of homologous animal species.

Abstract
The present study evaluated the clinical course of patients with mild cognitive impairment (MCI), the pattern of electroencephalography (EEG) changes following cognitive deterioration, as well as the potential of neurophysiological measures in predicting dementia. Twenty-seven subjects with MCI were followed for a mean follow up period of 21 months. Fourteen subjects (52%) progressed (P MCI) to clinically manifest Alzheimer's disease (AD), and 13 (48%) remained stable (S MCI). The two MCI subgroups did not differ in baseline EEG measures between each other and the healthy controls (n = 16), but had significantly lower theta relative power at left temporal, temporo-occipital, centro-parietal, and right temporo-occipital derivation when compared to the reference AD group (n = 15). The P MCI baseline alpha band temporo-parietal coherence, alpha relative power values at left temporal and temporo-occipital derivations, theta relative power values at frontal derivations, and the mean frequency at centro-parietal and temporo-occipital derivations overlapped with those for AD and control groups. After the follow-up, the P MCI patients had significantly higher theta relative power and lower beta relative power and mean frequency at the temporal and temporo-occipital derivations. A logistic regression model of baseline EEG values adjusted for baseline Mini-Mental Test Examination showed that the important predictors were alpha and theta relative power and mean frequency from left temporo-occipital derivation (T5-O1), which classified 85% of MCI subjects correctly.

Abstract
Using an experimental in vitro culture system, we investigated the effect of clarithromycin on biofilm formation by a leucine-requiring Pseudomonas aeruginosa mutant strain (HU1). Biofilm formation on celldesks in a chemically defined medium was assessed by viable cell count as well as by measurement of glycocalyx production and scanning electron-microscopic observation. Cells proliferated exponentially until day 3 and remained stationary afterwards. The amount of glycocalyx, simultaneously semiquantified, showed a linear increase from day 1 to day 12. Scanning electron microscopy revealed firm biofilms on day 5. Three different concentrations of Clarithromycin (CAM) (minimum inhibitory concentration MIC 64 microg/ml) were added continuously at the early and late phases of biofilm formation, and the antibiofilm effect of CAM was evaluated by the changes in cell count and glycocalyx production. CAM was effective on biofilms at 100 microg/ml but neither at 1 nor at 10 microg/ml. It is suggested that glycocalyx production started following bacterial multiplication and continued even after the cells had entered the stationary phase to form mature biofilms. No antibiofilm effect of CAM was observed at sub-MIC.

Abstract
PURPOSE Intracytoplasmic sperm injection (ICSI) has been validated as a useful treatment in severe male-factor patients who could not achieve fertilization and live births by conventional in vitro fertilization treatment. To examine the impact of male factors on ICSI outcome, clinical laboratory data were retrospectively analyzed. METHODS One hundred two cycles of ICSI treatment indicated by severe male-factor infertility were entered into this study. Sperm parameters including sperm motility, sperm concentration, and sperm motility index assessed by the Sperm Quality Analyzer were evaluated. RESULTS Five hundred seventy-six metaphase II oocytes retrieved were manipulated. The normal fertilization (2 PN) rate per oocyte was 64.9 +/- 26.0% (mean +/- SD). Of the 99 transfers, 31 clinical pregnancies were obtained, yielding an average pregnancy rate of 31.3% per transfer. The mean sperm motility, sperm concentration, and sperm motility index were 20.3 +/- 16.1% (range, 0 to 50%), 18.2 +/- 25.1 x 10(6)/ml (range, < 1 to 150 x 10(6)/ml), and 31.2 +/- 45.0 (range, 0 to 220), respectively. Sperm concentration did not have a significant impact on fertilization rate by ICSI. In four cases, ICSI was performed using totally immotile sperm and the fertilization rate was 43.5%, which was significantly lower than that of some of the other sperm motility groups, and no pregnancy could be achieved. In 14 cases in which the sperm motility index assessed by the Sperm Quality Analyzer was 0, the fertilization rate (50.0%) was significantly lower than in most of the other sperm motility index groups. CONCLUSIONS These findings suggest that in severe male-factor cases with totally immotile sperm or a sperm motility index of 0, the selection of good-quality sperm should be verified before injection.

Abstract
OBJECTIVE To study the progression of Alzheimer's disease (AD) at a very early stage and to evaluate clinical markers of presymptomatic AD. SETTING Longitudinal study at a university hospital. SUBJECTS A Swedish family harboring a double mutation at codons 670/671 of the APP gene on chromosome 21 was followed longitudinally for 3 years. Both mutation carriers and noncarriers participated. OUTCOME MEASUREMENTS Results from clinical investigations, electroencephalography, neuropsychological and neuroradiological examinations including magnetic resonance imaging, single-photon emission computed tomography and positron emission tomography were assessed and compared on two or more occasions. MAIN OUTCOME During follow-up, 1 initially asymptomatic mutation carrier who was near the expected age of onset for this family, developed cognitive symptoms, and at the end of the follow-up fulfilled the diagnostic criteria for AD. One mutation carrier with cognitive symptoms at the first examination showed clinical deterioration and was diagnosed with AD. One demented mutation carrier died and was shown to have typical AD neuropathology at autopsy. The two remaining asymptomatic mutation carriers, as well as all the noncarriers were asymptomatic. These mutation carriers who were near the expected age of onset of AD but without clinical signs of the disease, did not show changes in either electrophysiological parameters or volumes of the temporal lobes. However, in these 2 individuals the blood flow in the temporal lobe showed intermediate values between the symptomatic mutation carriers and healthy noncarriers. Two neuropsychological tests showed a deterioration that paralleled clinical symptoms in 1 of the mutation carriers who was close to the expected age of onset and who at the end of the follow-up had clinical signs of AD. In the same subject, brain glucose metabolism was pathologically reduced in the temporal lobes before other clinical symptoms were obvious. CONCLUSION In this familial form of AD a reduced temporal lobe glucose metabolism was indicative of AD before the expected clinical onset. Reduced glucose metabolism even preceded the development of subjective or objective cognitive dysfunction and might therefore serve as a clinical marker for AD before the onset of clinical symptoms. Reduced cerebral blood flow in the temporal lobes and cognitive deterioration paralleled the clinical decline in the early stage of the disease. Copyrightz1999S.KargerAG,Basel

Abstract
The purpose of this study was to investigate if the outcome of ICSI was influenced by epididymal sperm motility in frozen-thawed specimens. A total of 18 ICSI treatment cycles using spermatozoa retrieved by microsurgical epididymal sperm aspiration (MESA) were analysed retrospectively. Cryopreservation of epididymal spermatozoa was performed when enough epididymal aspirates were collected. Sixty-nine out of 126 oocytes injected with spermatozoa retrieved by MESA were fertilized, giving a fertilization rate of 54.8%. Out of 18 embryo transfer cycles, 6 (33.3%) achieved pregnancies. Fresh epididymal spermatozoa were used in 5 cycles while frozen-thawed epididymal spermatozoa were used in 13 cycles for ICSI. The fertilization rates were 68.6% (35/51) in the former group and 45.3% (34/75) in the latter group, respectively. There was a significant difference between the two groups (p < 0.05). In ICSI treatments using fresh epididymal spermatozoa, the cells used for injection were all motile. However, motile epididymal spermatozoa could be used in only five ICSI treatment cycles after freeze-thawing. In 6 cycles, only immotile sperm were used for injection of frozen-thawed spermatozoa. The fertilization rate in each group was 68.4% (13/19) and 31.6% (12/38), respectively. There was a significant difference between these groups (p < 0.01). These results indicate that the outcome of ICSI was influenced by sperm motility in frozen-thawed epididymal specimens. When no sperm motility could be recovered after freeze-thawing even with chemical treatments, consideration should be given to retrieving fresh epididymal spermatozoa again to achieve a better fertilization rate in such patients.

Abstract
STUDY OBJECTIVE To examine the difference in the mechanisms of bronchial hyperresponsiveness (BHR) in nonatopic asthma and in atopic asthma, we studied bronchial reactivity against nonspecific stimuli in children with atopic asthma and nonatopic asthma. DESIGN AND PARTICIPANTS Fourteen children with nonatopic asthma, 24 children with atopic asthma, and 20 age-matched controls participated in this study. MEASUREMENTS Inhalation challenge was performed by administering progressively doubling doses of methacholine with a continuous inhalation provocation method. The speed of bronchoconstriction to methacholine (Sm) and the speed of reversal of bronchoconstriction to methacholine after inhalation of a beta2-agonist (r-Sm), which was considered to represent the effect of the beta2-agonist, were calculated from the dose-response curve. RESULTS The value of Sm was higher in the nonatopic asthma group than in the atopic asthma group and the control group. The value of r-Sm was also higher in the nonatopic asthma group than in the atopic asthma group, but did not differ from that in the control group. CONCLUSION These results indicate that bronchial reactivity against methacholine and the beta2-agonist was greater in nonatopic asthma than in atopic asthma, and that the mechanism of BHR in children with nonatopic asthma may differ from that in children with atopic asthma.

Abstract
A rare case of successful pregnancy in a woman with early-stage endometrial adenocarcinoma conservatively treated is presented. The patient, having polycystic ovaries, was initially diagnosed with hyperplasia of the endometrium and treated with several cycles of ovulation induction following intrauterine insemination. Then dilatation and curettage were carried out when hysteroscopy was performed. The histology report identified a well-differentiated adenocarcinoma of the endometrium. After repeated endometrial curettage, in-vitro fertilization and embryo transfer were introduced for immediate treatment of the patient's infertility in order to avoid the risk of recurrence of neoplastic endometrial lesions by oestrogens. A single pregnancy was achieved after transfer of the embryos obtained after intracytoplasmic sperm injection. This was performed due to the poor semen characteristics (asthenozoospermia). The patient delivered a healthy normal male infant at term. A transvaginal ultrasound examination 2 months after delivery showed a smooth, linear endometrium. Moreover, the histology report after endometrial biopsy was free of any malignancies. The patient now desires another pregnancy. We conclude that conservative treatment of early-stage endometrial adenocarcinoma in young women wishing to preserve fertility should be considered in carefully selected cases. Assisted reproductive technologies may be helpful for immediate achievement of pregnancy in such patients.

Abstract
Here we report the first case of prenatally diagnosed fetal renal mesoblastic nephroma occurring after transfer of a cryopreserved embryo. A 37 year old woman, having immunological infertility, was treated by in-vitro fertilization (IVF) and embryo transfer. Following unsuccessful IVF using fresh embryos, the patient conceived after transfer of cryopreserved-thawed embryos. The chromosomal analysis identified a normal karyotype at 16 weeks' gestation when amniocentesis was performed. The pregnancy course was uneventful until 28 weeks' gestation when polyhydramnios associated with fetal renal tumour was detected using ultrasonography. A male infant weighing 2564 g was born via Caesarean section at 34 weeks' gestation. A left nephrectomy was performed 5 days after delivery and the tumour was identified histologically as a mesoblastic nephroma. The postoperative course was uncomplicated to this point.

Abstract
PURPOSE The aim of the present study was to investigate the reason residual fragments from upper urinary tract calculi failed to clear after successful extracorporeal shock wave lithotripsy (ESWL). METHODS Risk factors were analyzed in 161 patients with residual fragments (< or = 4 mm) that had remained for more than 3 months after ESWL. The factors examined in the present study were gender, a history of urolithiasis, the number, location and size of stones, hydronephrosis 3 months after ESWL and bacteriuria before ESWL. The mean follow-up period was 20.0 months (range 6-69 months). RESULTS The overall stone-free rate was 14.3%. The stone-free rate in patients with multiple stones or hydronephrosis 3 months after ESWL was significantly lower than that in patients without these conditions (P < 0.05 and P < 0.01, respectively). The cumulative non-clearance rate in patients with hydronephrosis was significantly higher than in patients without this condition (P < 0.05). Results of Cox's proportional hazards model indicated that hydronephrosis was the most important and only significant factor for failure to clear of the seven factors investigated (P < 0.05). CONCLUSION Hydronephrosis was most highly correlated with the fate of residual fragments after ESWL.

Abstract
In the central nervous system, many cell adhesion molecules are known to participate in the establishment and remodeling of the neural circuit. Some of the cell adhesion molecules are known to be anchored to the membrane by the glycosylphosphatidylinositol (GPI) inserted to their C termini, and many GPI-anchored proteins are known to be localized in a Triton-insoluble membrane fraction of low density or so-called "raft." In this study, we surveyed the GPI-anchored proteins in the Triton-insoluble low density fraction from 2-week-old rat brain by solubilization with phosphatidylinositol-specific phospholipase C. By Western blotting and partial peptide sequencing after the deglycosylation with peptide N-glycosidase F, the presence of Thy-1, F3/contactin, and T-cadherin was shown. In addition, one of the major proteins, having an apparent molecular mass of 36 kDa after the peptide N-glycosidase F digestion, was found to be a novel protein. The result of cDNA cloning showed that the protein is an immunoglobulin superfamily member with three C2 domains and has six putative glycosylation sites. Since this protein shows high sequence similarity to IgLON family members including LAMP, OBCAM, neurotrimin, CEPU-1, AvGP50, and GP55, we termed this protein Kilon (a kindred of IgLON). Kilon-specific monoclonal antibodies were produced, and Western blotting analysis showed that expression of Kilon is restricted to brain, and Kilon has an apparent molecular mass of 46 kDa in SDS-polyacrylamide gel electrophoresis in its expressed form. In brain, the expression of Kilon is already detected in E16 stage, and its level gradually increases during development. Kilon immunostaining was observed in the cerebral cortex and hippocampus, in which the strongly stained puncta were observed on dendrites and soma of pyramidal neurons.

Abstract
A fetus was diagnosed with prune-belly syndrome (PBS) found by ultrasound demonstration of cystomegaly at 12 weeks' gestation. Fetal urinary electrolyte and beta2-microglobulin concentrations at 14 weeks' gestation indicated a poor renal prognosis. The pregnancy was therefore terminated. An autopsy showed defects of the abdominal wall muscles and megalocystis caused by severe urethral obstruction. However, the kidneys were histologically normal. Together with previous reports, the present case suggests that renal dysplasia in PBS with severe uretheral obstruction may develop after 14 weeks' gestation. We discuss the possibility of preventing the development of renal dysplasia in PBS by early prenatal decompression of the obstructed fetal urinary tract.

Abstract
The growth rate of biofilm bacteria of a leucine-requiring mutant Pseudomonas aeruginosa HU1 was regulated by the leucine concentration in a chemically-defined medium. The semiquantitative measurement of glycocalyx and scanning electron microscopy revealed that the kinetics of HU1-biofilm formation were dependent on the incubation time and the leucine concentration in the medium. The effect of the growth rate of biofilm cells on their susceptibility to antimicrobial agents, three beta-lactams and four fluoroquinolones, was evaluated. beta-Lactams showed weak bactericidal activity to biofilm cells; the activity was greater in younger biofilm cells growing in high concentrations of leucine. Fluoroquinolones revealed strong bactericidal activity to biofilm bacteria regardless of the growth rate. The following is suggested: the bactericidal action of beta-lactams against biofilm cells is affected by the cell growth rate, while that of fluoroquinolones is considerably greater and independent on the growth rate.

Abstract
Nerve growth factor (NGF) is important for the survival and maintenance of central cholinergic neurons, a signalling system impaired in Alzheimer's disease. We have treated 3 patients with Alzheimer's disease with a total of 6.6 mg NGF administered continuously into the lateral cerebral ventricle for 3 months in the first 2 patients and a total of 0.55 mg for 3 shorter periods in the third patient. The patients were extensively evaluated with clinical, neuropsychological, neurophysiological and neuroradiological techniques. Three months after the NGF treatment ended, a significant increase in nicotine binding was found in several brain areas in the first 2 patients and in the hippocampus in the third patient as studied by positron emission tomography. A clear cognitive amelioration could not be demonstrated, although a few neuropsychology tests showed slight improvements. The amount of slow-wave cortical activity as studied by electroencephalography was reduced in the first 2 patients. Two negative side effects occurred with NGF treatment: first, a dull, constant back pain was observed in all 3 patients, which in 1 patient was aggravated by axial loading resulting in sharp, shooting pain of short duration. When stopping the NGF infusion, the pain disappeared within a couple of days. Reducing the dose of NGF lessened the pain. Secondly, a marked weight reduction during the infusion with a clear weight gain after ending the infusion was seen in the first 2 patients. We conclude from this limited trial that, while long-term intracerebroventricular NGF administration may cause certain potentially beneficial effects, the intraventricular route of administration is also associated with negative side effects that appear to outweigh the positive effects of the present protocol. Alternative routes of administration, and/or lower doses of NGF, perhaps combined with low doses of other neurotrophic factors, may shift this balance in favor of positive effects.
