Abstract
BACKGROUND The fetal brain is vulnerable to severe and sustained hypoxia during and after birth, which can lead to hypoxic-ischemic encephalopathy (HIE). HIE is characterized by clinical and laboratory evidence of acute or subacute brain injury. The role of cytokines in the pathogenesis of brain injury and their relation to neurological outcomes of asphyxiated neonates are not fully understood. In this study, we investigated cytokine profile related to cerebral palsy (CP) with neonatal hypoxic ischemic encephalopathy (HIE) and HIE severity. METHODS Eligible subjects were HIE newborns with a gestational age between 36 and 42 weeks. We included newborns who was born at our NICU and did not admit to NICU as healthy controls. The study comprised 52 newborns, including 13 with mild to severe HIE and 39 healthy control. Serum cytokine profiles were performed using a LUMINEX cytokine kit (R&D Systems). RESULTS VEGF, MCP-1, IL-15, IL-12p70, IL-12p40, IL-1Ra, IL-2, IL-6, IL-7, IL-8, IL-10, IFN-γ, G-CSF and eotaxin in the HIE patients were significantly increased compared with the healthy neonates. In the subgroup analysis, IL-6 and G-CSF were significantly increased in CP infants (n = 5) compared with non-CP infants (n = 8). Five and eight HIE patients were classified into the mild HIE and moderate-severe HIE groups, respectively. IL-6, 10, 1Ra, and G-CSF in the moderate-severe HIE group were significantly higher than those in the mild HIE group. CONCLUSION We demonstrated that higher serum IL-6 and G-CSF at birth in HIE patients were associated with CP and moderate-severe HIE.

Abstract
OBJECTIVES Dementia is common in people over the age of 65 years, with 80% of people with dementia older than 75 years. Previous studies have linked dementia to late-life depression, but the association between dementia and mid-life depression is poorly understood. Depression is a preventable and treatable medical condition, which means it is a modifiable factor that can potentially prevent or delay dementia. This study aimed to identify the association between dementia and depression within the life course. DESIGN A nationwide, retrospective propensity score matched cohort study associating dementia with depression. Depression diagnosed between the ages of 45 and 64 years was classified as 'mid-life' and 'late-life' if diagnosed at 65 years or older. Patients were considered to have depression when one or more International Statistical Classification of Diseases and Related Health Problems, 10th revision codes for depression were recorded as primary or secondary diagnosis. SETTING National Health Insurance Service-National Sample Cohort database of the National Health Insurance Service in South Korea, containing patient data from 2002 to 2013. PARTICIPANTS The study included 1824 and 374 852 patients in the case and control groups, respectively. A logistic regression analysis with complex sampling design was performed after adjusting for covariates, using the propensity score matching method without callipers, with a 1:1 nearest neighbour matching algorithm. PRIMARY AND SECONDARY OUTCOME MEASURES The association of mid-onset and late-onset depression with dementia in terms of sociodemographic characteristics, such as sex and age, within the Korean population. RESULTS Dementia was significantly associated with the presence of depression (OR=2.20, 95% CI=1.53-3.14); in particular, female patients with depression and patients aged 45-64 years with depression had increased odds of dementia (OR=2.65, 95% CI=1.78-3.93 and OR=2.72, 95% CI=1.41-5.24, respectively) CONCLUSION: Depression is an associated factor for dementia, especially among people aged 45-64 years (mid-life).

Abstract
We investigated whether cognitive decline could be explained by resting-state electroencephalography (EEG) biomarkers measured in prefrontal regions that reflect the slowing of intrinsic EEG oscillations. In an aged population dwelling in a rural community (total = 496, males = 165, females = 331), we estimated the global cognitive decline using the Mini-Mental State Examination (MMSE) and measured resting-state EEG parameters at the prefrontal regions of Fp1 and Fp2 in an eyes-closed state. Using a tertile split method, the subjects were classified as T3 (MMSE 28-30, N = 162), T2 (MMSE 25-27, N = 179), or T1 (MMSE ≤ 24, N = 155). The EEG slowing biomarkers of the median frequency, peak frequency and alpha-to-theta ratio decreased as the MMSE scores decreased from T2 to T1 for both sexes (-5.19 ≤ t-value ≤ -3.41 for males and -7.24 ≤ t-value ≤ -4.43 for females) after adjusting for age and education level. Using a double cross-validation procedure, we developed a prediction model for the MMSE scores using the EEG slowing biomarkers and demographic covariates of sex, age and education level. The maximum intraclass correlation coefficient between the MMSE scores and model-predicted values was 0.757 with RMSE = 2.685. The resting-state EEG biomarkers showed significant changes in people with early cognitive decline and correlated well with the MMSE scores. Resting-state EEG slowing measured in the prefrontal regions may be useful for the screening and follow-up of global cognitive decline in elderly individuals.

Abstract
Phytoestrogens have been demonstrated to inhibit tumor induction; however, their molecular mechanisms of action have remained elusive. The present study aimed to investigate the effects of a phytoestrogen, apigenin, on proliferation and apoptosis of the human epidermal growth factor receptor 2 (HER2)-expressing breast cancer cell line SKBR3. Proliferation assay, MTT assay, fluorescence-activated cell sorting analysis, western blot analysis, immunocytochemistry, reverse transcription-polymerase chain reaction and ELISA assay were used in the present study. The results of the present study indicated that apigenin inhibited the proliferation of SKBR3 cells in a dose-and time-dependent manner. This inhibition of growth was accompanied by an increase in the sub-G0/G1 apoptotic population. Furthermore, apigenin enhanced the expression levels of cleaved caspase-8 and -3, and induced the cleavage of poly(adenosine diphosphate ribose) polymerase in SKBR3 cells, confirming that apigenin promotes apoptosis via a caspase-dependent pathway. Apigenin additionally reduced the expression of phosphorylated (p)-janus kinase 2 and p-signal transducer and activator of transcription 3 (STAT3), inhibited CoCl2-induced vascular endothelial growth factor (VEGF) secretion and decreased the nuclear localization of STAT3. The STAT3 inhibitor S31-201 decreased the cellular proliferation rate and reduced the expression of p-STAT3 and VEGF. Therefore, these results suggested that apigenin induced apoptosis via the inhibition of STAT3 signaling in SKBR3 cells. In conclusion, the results of the present study indicated that apigenin may be a potentially useful compound for the prevention or treatment of HER2-overexpressing breast cancer.

Abstract
Background Obesity, which is described as excessive or abnormal body fat, increases the risk of diet-related diseases. In Korea and around the world, the prevalence of obesity has grown annually from 1998 to 2008. This growth has continued despite various therapeutic efforts. The discovery of new and alternative treatments for obesity should be considered an important priority. Taeumjowi-tang (TJ001), a traditional Korean medicinal extract consisting of eight herbs, is a widely used herbal remedy for obesity in Korea. However, the efficacy and safety of TJ001 have not been fully investigated in a clinical trial. The purpose of this pilot study is to estimate obesity-related parameters and to assess the efficacy and safety of TJ001. Methods Our study is a randomised, double-blind, placebo-controlled, multicentre clinical trial of Taeumjowi-tang (TJ001). For this study, we will recruit obese Korean patients of both sexes, ages 18 to 65 years, from four university hospitals. A total of 104 subjects will be recruited. The participants will receive either 7 g of TJ001 or a placebo three times daily for 12 weeks. The primary end point will be the rate of subjects who lose at least 5% of their baseline body weight. The secondary end points will be changes in body weight, body mass index, waist circumference, hip circumference, waist/hip circumference ratio, lipid profiles, body fat composition, blood pressure, fasting glucose concentration, C-reactive protein and questionnaires related to the quality of life. The outcomes will be measured every 4 weeks. The study period will be 12 weeks and will include a total of five visits with each subject (at screening and at 0, 4, 8 and 12 weeks). Conclusions The results of our study will inform various estimates of TJ001 and will serve as the basis for a larger-scale trial. This study will assess the efficacy and safety of TJ001 as an alternative herbal remedy for obesity. Trial registration Current Controlled Trials ISRCTN87153759

Abstract
Telomere length is critical for chromosome stability that affects cell proliferation and survival. Telomere elongation by telomerase is inhibited by the telomeric protein, TRF1. Tankyrase-1 (TNKS1) poly(ADP-ribosyl)ates TRF1 and releases TRF1 from telomeres, thereby allowing access of telomerase to the telomeres. TNKS1-mediated poly(ADP-ribosyl)ation also appears to be crucial for regulating the mitotic cell cycle. In searching for proteins that interact with polo-like kinase-1 (Plk1) by using complex proteomics, we identified TNKS1 as a novel Plk1-binding protein. Here, we report that Plk1 forms a complex with TNKS1 in vitro and in vivo, and phosphorylates TNKS1. Phosphorylation of TNKS1 by Plk1 appears to increase TNKS1 stability and telomeric poly(ADP-ribose) polymerase (PARP) activity. By contrast, targeted inhibition of Plk1 or mutation of phosphorylation sites decreased the stability and PARP activity of TNKS1, leading to distort mitotic spindle-pole assembly and telomeric ends. Taken together, our results provide evidence of a novel molecular mechanism in which phosphorylation of TNKS1 by Plk1 may help regulate mitotic spindle assembly and promote telomeric chromatin maintenance.

Abstract
OBJECTIVES Our purpose was to evaluate interaction of green tea consumption and abdominal obesity as related factors for lacunar infarction in Korean women. DESIGN A hospital-based, incident case-control study. SETTINGS The Prevention and Managements of Stroke in Women study. PARTICIPANTS Cases (n=233) of first incident lacunar infarction were enrolled and matched by age to stroke-free hospital controls (n=204). MEASUREMENTS The data were collected through face-to-face interviews by well trained research assistants to assess demographic, medical, lifestyle, marital status, religions status, green tea consumptions, family history of stroke, smoking status, alcohol consumption, meat and vegetable intake frequency, and past history of hypertension. Biochemical analysis, fasting blood specimens for lipid, glucose, and cholesterol level were acquired. RESULTS Compared with the non green tea consumer and obese women group, only the green tea consumption and non obese women group had a protective effect of lacunar infarction when adjusted for age, and age plus diet factors (OR, 0.23; 95% CI, 0.09, 0.59; OR, 0.21; 95% CI, 0.08, 0.56 respectively), but lost their significance after adjustment for age, diet factors, vascular risk factors and full model included atherogenic index factors (OR, 0.32; 95% CI, 0.09 to 1.01; OR, 0.49; 95% CI, 0.12, 1.89 respectively). CONCLUSIONS The interaction of green tea consumption and non obesity have reduced risk of lacunar infarction, but not after adjustment for age, diet factors, vascular risk factors and atherogenic index. Also individually green tea consumption and abdominal obesity have failed to find an independent relationship with lacunar infarction after adjustment by all risk factors. Green tea consumption and green tea consumption with non obese group seemed to have a protective effect for lacunar infarction. In the results of our study, these results still remain controversial, and then we need further and larger study to get at the root of real causal effect of both relationships.

Therefore, preventing diabetes at an earlier stage is very important. Despite advances in antidiabetic agents, we have not yet achieved any satisfying results in treating diabetes. Among various treatments, medicinal herbs and supplements for diabetes are reported to show generally good efficacy and safety data. In particular, PURIAM110, a compound from orange fruits and mulberry leaves, is supposed to prevent the progress of type II diabetes mellitus and improve diabetic symptoms. This is the first reported pilot study about the protective effect of the orange fruits and mulberry leaves mixture against pre-diabetes on Korean adults. Based on these positive results of herb-derived components, extended studies of dietary supplements have to be done to suggest confirmative evidences. Methods/Design The efficacy and safety study of PURIAM110 is a double-blinded, placebo-controlled, randomized, and multi-center clinical trial. A total of 45 subjects will participate in this study for 6 weeks. Discussion The present protocol will confirm the efficacy and safety of PURIAM110 for pre-diabetes, suggesting more basic knowledge to conduct further randomized controlled trials (RCT). In addition, PURIAM110 can be an alternative dietary supplemental remedy for diabetes patients. Trial Registration ISRCTN: ISRCTN44779824

Abstract
Aging is a progressive process related to the accumulation of oxidative damage and neuroinflammation. We tried to find the anti-amnesic effect of the Scutellaria baicalens Georgia (SBG) ethanol extract and its major ingredients. The antioxidative effect of SBG on the mice model with memory impairment induced by chronic injection of D-galactose and sodium nitrate was studied. The Y-maze test was used to evaluate the learning and memory function of mice. The activities of superoxide dismutase, catalase and the content of malondialdehyde in brain tissue were used for the antioxidation activities. Neuropathological alteration and expression of bcl-2 protein were investigated in the hippocampus by immunohistochemical staining. ROS, neuroinflammation and apoptosis related molecules expression such as Cox-2, iNOS, procaspase-3, cleaved caspase-3, 8 and 9, bcl-2 and bax protein and the products of iNOS and Cox-2, NO, PGE2, were studied using LPS-activated Raw 264.7 cells and microglia BV2 cells. The cognition of mice was significantly improved by the treatment of baicalein and 50 and 100 mg/kg of SBG in Y-maze test. Both SBG groups showed strong antioxidation, antiinflammation effects with significantly decreased iNOS and Cox-2 expression, NO and PGE2 production, increased bcl-2 and decreased bax and cleaved caspase-3 protein expression in LPS induced Raw 264.7 and BV2 cells. We also found that apoptotic pathway was caused by the intrinsic mitochondrial pathway with the decreased cleaved caspase-9 and unchanged cleaved caspase-8 expression. These findings suggest that SBG, especially high dose, 100 mg/kg, improved the memory impairments significantly and showed antioxidation, antiinflammation and intrinsic caspase-mediated apoptosis effects.

Abstract
The incidence of measles epidemics has decreased recently owing to the development and widespread use of measles vaccine in the United States of America and Europe. However, repeated measles epidemics have been reported in Japan. Here, the authors report a case of an extremely low body weight infant (ELBWI) whose mother had a measles virus infection. Real-time PCR was performed on the infant's blood and urine samples and skin, nasal secretion, and anal swabs, as well as on the mother's breast milk, blood samples and throat swabs. The infant was found to be positive for measles virus by PCR, but not immunoglobulin M positive. An earlier report showed that there were no such cases in which the patient was found to be positive for measles virus by real-time PCR but was not infected by the measles virus.

Abstract
KI0477959 (Herbkines) has been used for the purpose of development of physical strength in wasting diseases, like cancer. In the present study, apoptosis-inducing activities of butanol fraction of KI0477959 were studied in human leukemia cell line, HL-60 cells. KI0477959 increased cytotoxicity but had less effect on human peripheral blood mononuclear cells. KI0477959-induced apoptosis was accompanied by activation of caspase-3 and specific proteolytic cleavage of poly-ADP-ribose polymerase. Increased apoptosis was reduced by treatment with p38 and extracellular signal-regulated protein kinase (ERK) inhibitors. These results suggest that KI0477959 induces apoptosis through activation of caspase-3, p38, and ERK in HL-60 cells.

Abstract
Progress during the past decade in non-linear dynamics and instability theory has provided useful tools for understanding spatio-temporal pattern formation. Procedures which apply principle component analysis (using the Karhunen-Loeve decomposition technique) to the multichannel electroencephalograph (EEG) time series have been developed. This technique shows localized changes of cortical functioning; it identifies increases and decreases of the activity of localized cortical regions over time while the subject performs a simple task or test. It can be used to demonstrate the change in cortical dynamics in response to a continuous challenge. Using 16 EEG electrodes, the technique provides spatio-temporal information not obtained with power spectrum analysis, and includes the weighted information given with omega complexity. As an application, we performed a pattern analysis of sleep-deprived human EEG data in 20 healthy young men. Electroencephalograph recordings were performed on subjects for <2 min, with eyes closed after normal sleep and after 24 h of experimentally-induced sleep deprivation. The significant changes in the eigenvector components indicated the relative changes of local activity in the brain with progressive sleep deprivation. A sleep deprivation effect was observed, which was hemispherically correlated but with opposite directional dynamics. These changes were seen in the temporo-parietal regions bilaterally. The application of the technique showed that the simple test task was performed with a limited unilateral hemispheric involvement at baseline, but needed a much larger cortical participation with decreased frontal activity and increased coherence and bilateral hemispheric involvement. The calculations performed demonstrated that the same weighted changes as those obtained with omega complexity were shown, but the technique had the added advantage of showing the localized directional changes of the principle eigenvector at each studied electrode, pointing out the cortical localized region affected by the sleep deprivation and toward which direction the environmental challenge induced the spatial change. This methodology may allow the evaluation of changes in local dynamics in brain activity in normal and pathological conditions.

Abstract
A spatio-temporal analysis has been employed on EEG signals recorded in groups of patients with Alzheimer's disease (AD). The so-called Karhunen-Loeve analysis method was applied to four groups of subjects: 12 patients who were diagnosed as having severe AD, 8 mild AD patients, 10 vascular dementia patients, and 10 normal aged controls, to obtain the spatio-temporal eigenpatterns. The local difference of the global EEG pattern in mild AD patients from that of normal controls was expanded to the frontal regions in the case of severe AD. The analysis showed significant bilateral temporal functioning differences and inter-hemispheric connection difficulty, along with remarkable intra-hemispheric correlation in severe AD patients. Compared to the normal controls, severe AD patients' brains exhibit only weak local connections and correlations, resulting into limited harmonious inter-hemispheric information processing. The results from the spatio-temporal EEG study of AD patients can be considered to be due to a change in the relative activity of the brain corresponding to the pathologic variation in AD, and the results are in accordance with reported clinical studies.

Abstract
A 39-year-old woman with type 1 genuine stress urinary incontinence was treated using a novel extraperitoneal laparoscopic bladder neck suspension procedure with a bone-anchor suture fixation system. Operative time and blood loss were 2.5 and 50 g, respectively. The patient showed a remarkable improvement on chain cystography and in subjective and objective well-being with no complications, even 12 months after surgery. Extraperitoneal laparoscopic bladder neck suspension using the bone-anchor suture fixation system is an easy and feasible procedure.

Abstract
Using differential hybridization technique, cDNA that was a partial sequence of rat ribosomal protein L41 was isolated from fos- and src-transfected rat fibroblast 3Y1. The cDNA was named #31. Subsequently, the human counterpart(named hm3168) was cloned from a human melanoma cell line(M14) and the amino acid sequence deduced from the cDNA proved to be identical to that of HG-12. The gene expression of hm3168 was inducible by serum-stimulation. It reveals the possible up-regulation of the transcription via fos-mediated signal transduction. Northern-blot and Western-blot analyses showed a large expression of the #31 gene in the rat transformed cell lines.

Abstract
OBJECTIVES To assess technical preferences and current practice trends of retroperitoneal and pelvic extraperitoneal laparoscopy. METHODS A questionnaire survey of 36 selected urologic laparoscopic centers worldwide was performed. RESULTS Twenty-four centers (67%) responded. Overall, 3988 laparoscopic procedures were reported: transperitoneal approach (n = 2945) and retroperitoneal/extraperitoneal approach (n = 1043). Retroperitoneoscopic/extraperitoneoscopic procedures included adrenalectomy (n = 74), nephrectomy (n = 299), ureteral procedures (n = 166), pelvic lymph node dissection (n = 197), bladder neck suspension (n = 210), varix ligation (n = 91), and lumbar sympathectomy (n = 6). Mean number of total laparoscopic procedures performed in 1995 per center was 41 (range 5 to 86). Major complications occurred in 49 (4.7%) patients and included visceral complications in 26 (2.5%) patients and vascular complications in 23 (2.2%). Open conversion was performed in 69 (6.6%) patients, electively in 41 and emergently in 28 (visceral injuries, n = 16; vascular injuries, n = 1 2). Retroperitoneoscopy/extraperitoneoscopy is gaining in acceptance worldwide: in 1993, the mean estimated ratio of transperitoneal laparoscopic cases versus retroperitoneoscopic/ extraperitoneoscopic cases per center was 74:26; however, in 1996 the ratio was 49:51. CONCLUSIONS Retroperitoneoscopy and pelvic extraperitoneoscopy are important adjuncts to the laparoscopic armamentarium in urologic surgery. The overall major complication rate associated with retroperitoneoscopy/extraperitoneoscopy was 4.7%.

Abstract
PURPOSE We examine how the level of experience acquired by the laparoscopist affects the outcome of laparoscopic adrenalectomy and nephrectomy, and what is necessary to avoid complications in these surgeries. MATERIALS AND METHODS We retrospectively evaluated the experience levels of 8 urological laparoscopists between 1991 and 1995. In addition, other cases that were converted to open surgery were collected from the institutes with which the 8 laparoscopists were affiliated. RESULTS The rates of conversion to open surgery were 6.4% in 204 cases of adrenalectomy and 14.3% in 63 of nephrectomy. Conversion rates were related to blood loss volume but not operative time. The major causes of conversion were bleeding in 45% of cases and adhesion in 34%. There were no mortalities. Mean operative time decreased significantly, reaching that of open surgery as the number of procedures increased up to 20 adrenalectomies and 10 nephrectomies. The volume of blood lost remained low from the early experience. Blood transfusion rates were 4.4% for adrenalectomy and 11.1% for nephrectomy. CONCLUSIONS Operative time of these procedures decreased significantly with surgeon experience and reached that of open surgery. Cases in which adhesion is anticipated should be restricted to avoid conversion. These laparoscopic procedures are acceptable as a standard operative techniques for adrenal and renal diseases.

Abstract
After a single dose of cisplatin, the ability of peripheral blood mononuclear cells (PBMC) to generate lymphokine-activated killer (LAK) cells was significantly augmented in cancer patients. Based on this clinical finding, the patients with locally advanced esophageal carcinoma were thus treated with a combination of cisplatin and low-dose interleukin-2 (IL-2) in a neoadjuvant setting. Four patients with squamous cell carcinoma of the esophagus (T3 or T4 disease) were preoperatively treated with a regimen consisting of 50 mg/m2 cisplatin on day 1, followed by IL-2 from day 4 through day 8, when the ability of PBMC to generate LAK cells had been shown to be significantly augmented. After two to four courses of the preoperative therapy, one patient achieved a histologic CR, one showed PR and one MR. No severe toxicity was encountered. All patients thereafter underwent surgery. The median survival of these patients was 47.5 months and three of the patients had been disease free for 43 to 62 months after the initiation of the therapy. The combination of cisplatin and low-dose IL-2 administered in a neoadjuvant setting seems to result in an improved survival of locally advanced squamous cell carcinoma of the esophagus.

Abstract
The antigenic peptides encoded by tumor-rejection antigen genes, MAGE-1 and -3, have been identified, and various methods have been utilized for the in vitro induction of MAGE-specific, cytotoxic T lymphocytes (CTL) from peripheral blood mononuclear cells (PBMC) using synthetic peptides. However, all of these methods are technically demanding and thus have a relatively limited usefulness. We herein report a simple and efficient method for the vitro induction of specific CTL by using the HLA-A2-restricted MAGE-3 peptide from the PBMC of a healthy donor. CTL responses could thus be efficiently induced from unseparated PBMC by stimulation with freshly isolated, peptide-pulsed PBMC as antigen-presenting cells and by using interleukin-7 and keyhole limpet hemocyanin for the primary culture. The induced CTL could thus recognize and lyse not only HLA-A2 target cells pulsed with the peptide but also HLA-A2 tumor cells expressing MAGE-3, in an HLA-class-I-restricted manner. This simple method may, therefore, become a useful tool for investigating the potential peptides for tumor antigens as well as for developing various immunotherapeutic approaches for human malignant tumors.

Abstract
PURPOSE We attempted to confirm the possibility and feasibility of laparoscopic adrenalectomy via the retroperitoneal approach, and to compare results of the transperitoneal and retroperitoneal approaches. MATERIALS AND METHODS Three men and 8 women (mean age 39.6 years) with functioning adrenocortical tumors (primary aldosteronism in 5 and Cushing's syndrome in 6) underwent laparoscopic adrenalectomy via the retroperitoneal approach using a balloon dissection technique and a newly developed ultrasonic aspirator. Results were compared to those of 27 cases of transperitoneal laparoscopic adrenalectomy. RESULTS Although the retroperitoneal approach was successful in all 5 patients with primary aldosteronism, it succeeded in only 2 of the 6 cases of Cushing's syndrome. In 3 Cushing's syndrome cases the retroperitoneal approach was changed to the transperitoneal laparoscopic approach due to difficulty in exploration. Open laparotomy was required in 1 case of left Cushing's syndrome because of an inadvertent pancreatic injury. Subcutaneous emphysema developed in 6 patients without hypercapnia or prolonged postoperative symptoms. Mean operative time and blood loss, and time to oral intake and ambulation were 248.3 minutes, 151.4 ml., and 1.55 and 2 days, respectively. There was no difference between retroperitoneal and conventional transperitoneal laparoscopic adrenalectomy in regard to these factors or to convalescence. CONCLUSIONS Retroperitoneal laparoscopic adrenalectomy is feasible for primary aldosteronism. However, Cushing's syndrome is presently a much more difficult indication than primary aldosteronism for this new operative technique.

Abstract
BACKGROUND Removal of adrenal adenoma of Cushing's syndrome is believed to be more troublesome than primary aldosteronism because of large amount of retroperitoneal adipose tissue and bleeding from the fat. The objective of the present study was to evaluate the feasibility of laparoscopic adrenalectomy for Cushing's syndrome and comparison of the results of laparoscopic adrenalectomy between primary aldosteronism and Cushing's syndrome. METHODS From January 17, 1992, to July 31, 1993, laparoscopic adrenalectomies for functioning adrenal lesions were performed in 14 patients (five men, nine women), three of whom had Cushing's syndrome and 11 of whom had primary aldosteronism. RESULTS Operative times (mean +/- SD) for primary aldosteronism and Cushing's syndrome were 269.0 +/- 100.9 minutes and 253.7 +/- 57.9 minutes, respectively. No difference was noted in operative time, operative bleeding, and postoperative recovery between them. However, the weight of removed tissue from patients with Cushing's syndrome (20.00 +/- 8.17 gm) was greater than that from those with primary aldosteronism (6.64 +/- 2.01 gm). No operative complications occurred in patients with Cushing's syndrome. Ultrasonic aspiration and argon-beam coagulation were useful for laparoscopic adrenalectomy in patients with Cushing's syndrome. CONCLUSIONS Cushing's syndrome may be a good indication for laparoscopic operation.

Abstract
Between January 17, 1992 and July 31, 1993, 11 patients with primary aldosteronism, 3 with Cushing's syndrome and 3 with a nonfunctioning adrenal tumor underwent laparoscopic adrenalectomy at our university hospital. In every patient adrenal tumor was removed successfully with adjacent normal adrenal tissue. The initial 10 operations were performed without use of an ultrasonic aspirator or argon beam coagulator, and the subsequent 7 procedures were done with those items. There was no difference between the groups in intraoperative blood loss or operative time. However, the tumors in the former group were significantly smaller than those of the latter group (mean 6.70 gm. versus 13.43 gm., respectively, p < 0.05, t test). For right tumors the argon beam coagulator was useful to resect or coagulate the liver, since adrenal tumors were sometimes tightly attached to the liver and upward retraction sometimes caused liver laceration. In obese patients or those with Cushing's syndrome the ultrasonic aspirator was useful to remove retroperitoneal fat surrounding the adrenal tumor without injury to the small vessels. The mean hospital stay for these 17 patients (11.63 days) was significantly shorter than that of 16 patients with corresponding adrenal tumors undergoing open removal during the last 5 years (17.32 days, p < 0.05 t test). In conclusion, laparoscopic adrenalectomy is feasible for the surgical treatment of primary aldosteronism, Cushing's syndrome and nonfunctioning adrenal tumors. The ultrasonic aspirator and argon beam coagulator may be useful for laparoscopic adrenalectomy.

Abstract
In this series, we investigated the efficacy and advantage of laparoscopy for management of nonpalpable testis. Laparoscopic examination was performed in 10 boys, involving one with bilateral nonpalpable testis and 9 with a unilateral nonpalpable testis and a contralateral normal one, between August 1991 and September 1993 in our institution. Three testis were diagnosed as intraabdominal and 8 testis were diagnosed as probably intracanalicular with laparoscopy. Two boys with 3 intracanalicular testis underwent laparoscopic clipping of testicular vessels, and about 6 months later, they underwent the second stage of 2-stage Fowler-Stephens orchiopexy. Eight boys, diagnosed as probably intracanalicular type by laparoscopy, underwent surgical exploration with inguinal incision. Of 8 patients, only 1 boy underwent 1-stage orchiopexy, and the other 7 boys underwent orchiectomy because their gonads were extremely hypoplastic. About 1 year after orchiopexy, 3 testes were normal in both size and location. Laparoscopy seems to be useful for both evaluation and treatment of the nonpalpable testis.

Abstract
To assess the value of endothelin-1 (ET-1) in estimating renal injury in patients receiving high doses of cisplatin, urinary excretion of ET-1-like immunoreactivity (U-ET-1), beta 2-microglobulin (U-beta 2-MG), and N-acetyl-beta-d-glucosaminidase (NAG) were measured before, 1 week after, and 2 weeks after the administration of cisplatin in eight patients with testicular cancer (mean age, 33.3 years). Levels of U-ET-1/creatinine (Cr) during and 1 week after cisplatin treatment were significantly higher than before cisplatin treatment. There were no differences in U-ET-1/Cr levels during, 1 week after, and 2 weeks after cisplatin treatment. The level of U-beta 2-MG/Cr during cisplatin treatment was significantly higher than levels before, 1 week after, and 2 weeks after treatment. However, there were no differences in U-beta 2-MG/Cr levels before, 1 week after, and 2 weeks after cisplatin treatment. The level of U-NAG/Cr during cisplatin treatment was higher than levels before, 1 week after, and 2 weeks after treatment; U-NAG/Cr during cisplatin treatment was higher than levels before, 1 week after, and 2 weeks after treatment; U-NAG/Cr gradually decreased after cisplatin treatment. Among the three parameters, only U-ET-1/Cr maintained a higher level after cisplatin treatment. The U-beta 2-MG/Cr level returned most rapidly to normal after cisplatin treatment. Although U-ET-1/Cr did not show any significant correlation with U-NAG/Cr (r = 0.282, P = NS), it showed a significant correlation with U-beta 2-MG/Cr (r = 0.454, P < 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
1. Urinary excretion of endothelin-1-like immunoreactivity and urinary excretion of other parameters (beta 2-microglobulin, N-acetyl-beta-D-glucosaminidase and microalbumin) were measured before, within 1 week after and 2 weeks after the administration of cis-platinum in five young male patients with testicular cancer (mean age 33.0 years) and were compared. 2. Urinary endothelin-1-like immunoreactivity/creatinine during, 1 week after, and 2 weeks after cis-platinum treatment was significantly higher than before cis-platinum. There was no difference in urinary endothelin-1-like immunoreactivity/creatinine during, 1 week after and 2 weeks after cis-platinum. 3. Among the four parameters, urinary endothelin-1-like immunoreactivity/creatinine showed the highest level after cis-platinum treatment. Urinary beta 2-microglobulin/creatinine most rapidly returned to normal levels after cis-platinum. 4. Although urinary endothelin-1-like immunoreactivity/creatinine did not show any significant correlations with urinary N-acetyl-beta-D-glucosaminidase (r = 0.291, not significant) or urinary microalbumin/creatinine (r = 0.076, not significant), it showed a significant correlation with urinary beta 2-microglobulin/creatinine (r = 0.475, P < 0.05). 5. These results suggest that endothelin-1 may be a sensitive urinary parameter in detecting cis-platinum-induced renal tubular injury.

Abstract
BACKGROUND Although laparoscopic technique has become popular in the surgical field, the value of laparoscopy in the removal of adrenal gland is unknown. The objective of this study was to examine the feasibility of laparoscopic adrenalectomy. METHODS Between January 17, 1992, and March 16, 1993, 10 patients (four men, six women; mean, 48.2 years of age) with primary aldosteronism underwent laparoscopic adrenalectomy (seven of left adrenal gland and three of right adrenal gland) with almost the same devices as laparoscopic cholecystectomy. RESULTS Adrenal tumors were successfully removed with adjacent normal adrenal gland in every patient. The operative time ranged from 165 to 572 minutes (mean, 295 minutes), and the operative bleeding ranged from 50 to 920 ml (mean, 270.5 ml) without requiring blood transfusion. Only one patient required open hemostasis because of uncontrollable bleeding complicated by dislocation of vascular clip in spite of successful laparoscopic removal of adrenal tumor. There was no major complication except for this case. CONCLUSIONS Laparoscopic adrenalectomy is a relatively safe, alternative operative method for primary aldosteronism, but application of this technique to other types of adrenal lesions remains to be studied.

Abstract
We report two cases of left nephrectomy and one case of left adrenalectomy with our new laparoscopic procedure. We treated the left renal vein first using trans-duodenal-recess approach. The left renal vein could be detected after an incision into the parietal peritoneum on the left side of the duodenojejunal flexure (duodenal-recess) was performed. When the nephrectomy was performed, the renal artery and vein were transected using endoGIA. When the left adrenalectomy was performed, the adrenal vein was clipped and divide after lysis of the left renal vein. Our new method allowed the renal vein to be treated first, so the remainder of the operation could be performed without the risk of bleeding.

Abstract
To assess the value of endothelin-1 (ET-1) as a parameter of renal functional overload and the process of hyperfiltration, urinary excretion of ET-1-like immunoreactivity (U-ET-1) and urinary excretion of other parameters [beta 2-microglobulin (beta 2-MG), N-acetyl-beta-D-glucosaminidase (NAG), albumin (Alb) and 24-hour creatinine clearance (Ccr24)] were measured before, 1, 2 and 7 days after unilateral nephrectomy in 15 patients with unilateral renal lesions (renal cell cancer, renal pelvic cancer, ureteral cancer and renal tuberculosis) and after unilateral adrenalectomy in 5 patients with adrenal lesions. In the nephrectomy group (NX), Ccr24 significantly decreased at 1 and 2 days after the operation, but the other 4 parameters significantly increased after the operation as compared to preoperative values. In the adrenalectomy group (ADX), neither Ccr24 nor ET-1/Cr showed any change after the operation, but the other 3 parameters (beta 2-MG/Cr, NAG/Cr and Alb/Cr) significantly increased. Comparing the NX and ADX groups, both ET-1/Cr and beta 2-MG/Cr in NX were significantly higher than in ADX after the operation. On the other hand, neither NAG/Cr nor Alb/Cr in NX differed from values in ADX. Comparing ET-1/Cr and other parameters, only beta 2-MG showed a positive significant correlation. These results suggest that U-ET-1 may be an indicator of functional overload of the kidney.

Abstract
Urinary risk factors and inhibiting factors for urolithiasis, such as oxalate, calcium, phosphate, uric acid, citrate, and magnesium, were examined in 12 patients receiving continent urinary diversion, neobladder, or augmentation cystoplasty using intestine. These data were compared with the incidence of pouch stone formation. Ten (83.3%) of 12 patients had at least one risk factor, and 5 (41.7%) of 12 had two or more risk factors. Pouch stone developed in 4 (80%) of 5 patients with two or more risk factors, and in none of 7 patients with one or zero risk factors. The incidence of pouch stone in the former group was significantly higher than in the latter group. These results suggest that urinary reservoir operations should not be performed in patients with two or more risk factors for urolithiasis.

Abstract
Plasma endothelin-1 (ET-1)-like immunoreactivity in selective renal venous blood and peripheral venous blood was measured and compared with plasma renin activity and aldosterone level in a 26-year-old woman with suspected renovascular hypertension due to stenosis of the left renal artery. Although there was no significant step-up in plasma renin activity between the right and the left renal vein, left/right ratio of plasma ET-1 in the renal vein was 2.18. This case suggests that ET-1 may be one of the hypertensive mechanisms of suspected renovascular hypertension in addition to the renin-angiotensin system.

Abstract
Thirty-two elderly male patients with benign prostatic hypertrophy complaining of urinary retention were treated by polyurethane intraurethral stents. All of them were unfit for prostatic surgery due to the presence of several complications, and had been indwelt with a urethral balloon catheter. Cystometry before stent insertion was performed in 23 of the 32 patients. Eleven patients showed overactive bladder, 5 patients normal bladder, and 7 patients underactive bladder. Duration of stent indwelling ranged from 2 days to 22 months (mean 6.7 months), and stent could successfully function for more than 6 months in 20 of the 32 patients (62.5%). Nine of these 20 patients (45%) could keep continence of urine, and urinary tract infections improved in 7 of these 20 patients (35%). The stent failed in 4 of the 5 patients who had had previous operations for prostatic hypertrophy. In a comparison of the findings of urodynamic study prior to insertion of stent with the results of the stent, the results were significantly better in the patients with overactive or normal bladder than in those with underactive bladder (p < 0.05, chi-square test). Bladder stone formation was found in one patient and was the only complication among the 32 patients. In conclusion, stent placement without incontinence or urinary tract infection can be successful for more than 6 months in patients who do not have an underactive bladder and who had not had a previous prostatic operation.

Abstract
From January 17, 1992 to January 16, 1993, laparoscopic adrenalectomy was performed in 7 patients (3 men, 4 women) with primary aldosteronism ranging in age from 35 to 65 years (mean 48.7 years). Five of the adrenal lesions were on the left side and two were on the right. Five to six trocar-sheath units were used, and adrenal tumors were successfully removed with adjacent normal adrenal glands in all patients. The operative time ranged from 165 to 572 min (mean 302 min), operative blood loss was between 50 and 450 ml (mean 217.2 ml), and there was no major complication. In conclusion, laparoscopic adrenalectomy is a safe alternative operative method for primary aldosteronism, although application of this technique to other types of adrenal lesions remains to be examined.

Abstract
Intraurethral catheters (IUC) were used for elderly male patients with prostatic urethral obstruction (PUO) due to malignancy (MA) and benign prostatic hypertrophy (BPH). Thirty-three men complaining of urinary retention in spite of medical therapy at the risk for prostatic surgery underwent insertion of IUC (16Fr Puroflex, Angiomed Co., Ltd., Germany). Six of 33 were patients with PUO due to MA (5 prostatic cancer, and 1 urethral invasion of rectal cancer, mean 82.7 years old), and the other 27 were patients with BPH (average 80.1 years old). Follow-up period of the former ranged from 2 to 9 (mean 6.5) months, and that of the latter ranged from 6 to 23 months. Water filling cystometry (CMG) before the insertion of IUC and fluoroscopic voiding cystourethrography (VCU) just after insertion of IUC were performed. We defined normal CMG and normal VCU as normal bladder, overactive CMG and normal VCU as overactive bladder, and normal or poor sensitive CMG and underactive VCU as underactive bladder. Five of 27 BPH patients had previous prostatic operations (TUR-P, and/or balloon dilation), but 6 MA did not. All of MA (3 normal bladder, 2 overactive bladder, and 1 underactive bladder) voided satisfactorily, and average duration of IUC in place was 6.5 months without exchange of IUC. Although sixteen of 27 (59.3%) BPH patients voided satisfactorily, and average duration of IUC in place was 12.1 months without exchange of IUC, in the other 11 of these 27 BPH patients were removed IUC, and average duration of IUC in place was 4.7 weeks.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Since January, 1992, 8 patients with adrenal disease have been treated by laparoscopic surgery. There were 4 males and 4 females (35-65 years old), seven patients had primary aldosteronism and one non-functioning adrenal tumor. Six trocar-sheath units were placed in the upper abdomen. In case of the lesion being on the right side, the posterior layer of the peritoneum was incised at the point of the hepatic flexure of the colon and on the left side, the dissection was begun by dividing the peritoneal reflection over the lateral aspect of the descending colon, adrenal tumors were removed with normal adrenal gland. In all cases adrenal tumors were removed successfully. The operative time was from 165 to 572 (293 min., average) minutes and there was no major complication.

Abstract
Urinary risk factors and preventive factors for infectious calcium (Ca) urolithiasis formation, such as citrate, oxalate, Ca, phosphate, magnesium, and uric acid were examined more than 2 months after performing a urinary reservoir in 12 patients (R group) and ileal conduit in 10 patients (C group). There was no difference in the positive rate of risk factors between the two groups and also no difference in the positive rate of more than two risk factors between the two groups. Although four patients with more than two risk factors in the R group suffered from reservoir stones all of which included Ca-urolithiasis, none in the C group did. In the R group, the incidence of stone formation in patients with 2 or more risk factors was significantly higher than those in patients with 1 or no risk factor. In conclusion, the urinary reservoir operation should not be carried out in patients with more than two risk factors for urolithiasis formation, and urinary risk factors should be examined before reservoir operation.
