This study was carried out to determine whether concentrationsof the brain monoamines noradrenaline (NA), dopamine (DA), and5-hydroxytryptamine or serotonin (5-HT) are different in threeinbred strains of mice (C57BL/6J, C3H/He and DBA/2Cr) knownto differ in their preference to alcohol, when they were givena free choice of 10% (v/v) ethanol and tap water to drink for4 weeks. Mice of these three strains showed mean ethanol intakesof 4.41, 1.76 and 0.77 g/kg/day respectively. Levels of theabove brain monoamines did not change in the alcohol-preferringC57BL/6J mice, but in those with less preference for alcohol,C3H/He and DBA/2Cr, there were significant increases in DA and5-HT levels respectively during the 4-week experiment. Thesefindings suggest that inbred strains of mice show genetic differencesof susceptibility to ethanol and that the strains with a lowpreference for alcohol undergo neurochemical changes after exposureto 10% ethanol and water even by free choice. 相似文献

Pancreatic pseudocyst after pancreatic surgery is a relatively rare condition and conservative therapy is the common treatment of choice. When symptoms persist or complications follow, however, surgical treatment is considered. There have been reports on endoscopic cystoenterostomy since the early 1980s. We herein describe a case of postsurgical pancreatic pseudocyst treated successfully by endoscopic cystogastrostomy. A nineteen-year-old female showing left hypochondralgia and back pain with elevation of her serum amylase level, who had undergone enucleation of a solid cystic tumor in the body of the pancreas, was referred to our department. She was diagnosed as having a pseudocyst of the pancreas 5.8×4.5 cm in size at the site of enucleation by US and CT. Endoscopic retrograde pancreatography and endoscopic ultrasonography performed simultaneously revealed obstruction of the main pancreatic duct and a cystic change in the body-tail of the pancreas just behind the gastric wall of the upper body. An extrinsic compression was seen in the posterior wall of the upper body of the stomach endoscopically. An incision was made using a sphincterotome. A pigtail stent, 7.2 Fr in size, was placed to keep the patency of the fistula, which was removed one and a half months later. Her symptoms showed great improvement immediately after the procedure. Follow-up CT demonstrated no recurrence of the pseudocyst. 相似文献

Problem drinking is a serious public health problem in the workplace. However, few
Japanese epidemiological studies have investigated the occupational characteristics of
problem drinking. The purpose of this study is to clarify the occupational risk factors
for problem drinking among a Japanese working population. We used data from a
random-sampling survey about mental health and suicide, conducted among Hamamatsu City
residents aged 15 to 79 yr old during May and June in 2008. The relation between
occupational factors and problem drinking was analyzed with multiple logistic regression
models stratified by gender. CAGE questionnaire was used to assess problem drinking. With
regard to employment types, problem drinkers were more prevalent among self-employed
women. With regard to occupational types, clerical and service professions had more
problem drinkers of either sex, while administrative/managerial and sales professions had
more women with such problem. With regard to company size, male problem drinkers were more
prevalent in smaller companies than in larger ones. These results indicate that the
prevalence of problem drinkers in the workplace depends on where one works. It is
necessary to consider these characteristics to provide effective measures to address
problem drinking in the workplace. 相似文献

Background and objective: Bronchiolitis obliterans (BO) has been reported to develop following ingestion of Sauropus androgynus (SA), a leafy shrub distributed in Southeast Asia. Little is known about direct effects of SA on airway resident cells or haematopoietic cells in vitro. Identification of the SA component responsible for the development of BO would be an important key to elucidate its mechanism. We sought to elucidate the direct effects of SA on airway resident cells or haematopoietic cells and identify the SA element responsible for the pathogenesis of BO. Methods: SA dry powder was partitioned into fractions by solvent extraction. Human and murine monocytic cells, epithelial cells and endothelial cells were cultured with SA solution or fractions eluted from SA. We also investigated the effect of SA in vivo using a murine BO syndrome (BOS) model. Results: The aqueous fraction of SA induced significant increases of inflammatory cytokine and chemokine production from monocytic lineage cells. This fraction also induced significant apoptosis of endothelial cells and enhanced intraluminal obstructive fibrosis in allogeneic trachea allograft in the murine BOS model. We found individual differences in tumour necrosis factor α (TNF‐α) production from monocytes of healthy controls stimulated by this aqueous fraction of SA, whereas it induced high‐level TNF‐α production from monocytes of patients with SA‐induced BO. Conclusions: These results suggest that an aqueous fraction of SA may be responsible for the pathogenesis of BO. 相似文献

Although percutaneous transluminal balloon aortic valvuloplasty (PTAV) has been performed for congenital aortic stenosis in infants and children for several years, its efficacy and the associated aortic regurgitation (AR) have not been widely discussed. Percutaneous transluminal balloon aortic valvuloplasty using an Inoue balloon catheter was performed for congenital aortic stenosis in 12 patients (4–16 years old) in this study. The systolic aortic valve pressure gradient ranged from 42 to 111 mmHg before PTAV and became < 50 mmHg immediately after PTAV in 10 cases (83%). Eight of these 10 patients had no increase in the gradient during subsequent observation for a period of 9–40 months. Aortic regurgitation increased immediately after PTAV in nine cases (75%). It increased from grade 1 to grade 2 in eight cases and from grade 1 to grade 3 in one patient; no significant enlargement of the left ventricular end-diastolic diameter and no significant change in the left ventricular end-diastolic pressure (LVEDP) or the cardiac index was observed during follow-up in these patients. There was a correlation between the diameter of the balloon and efficacy; an appropriate diameter was considered to be about 90% of the aortic annular diameter. Changes in the hemodynamic parameter after PTAV with an Inoue balloon were small in most patients and this procedure is considered to be a treatment that should be attempted prior to surgery for congenital aortic stenosis. 相似文献

In order to investigate the physiological changes produced by the treatment of acrophobic patients body movement and Microvibration were measured before and after treatment. Eighteen acrophobic patients were assigned at random to 1 of the 2 groups: a treatment group (n= 8) and a non-treatment group (n= 10). The control group consisted of 16 healthy volunteers. Body movement area while viewing a slide of a high place or imagining a high place in the treatment group decreased significantly after treatment. Body movement of the control group showed almost no changes, and that of the non-treatment group was situated between the above-mentioned 2 groups. Simple body movements of the acrophobic patients without any stimulation of height were bigger than those of the control subjects. MV pattern of the treatment group had a tendency to improve under psychotherapy. Acrophobic patients had more abnormal MV patterns than the normal subjects. 相似文献

In the treatment of metastatic breast cancer, trastuzumab, a recombinant monoclonal antibody against human epidermal growth factor receptor 2 (HER2), is effective when tumor cells overexpress HER2 protein. Although some cases of extramammary Paget's disease (EMPD) also express HER2 protein, no case of EMPD has been reported to be treated with trastuzumab. A 75-year-old man who suffered from EMPD of the scrotum and inguinal region underwent a local excision and lymph node dissection. Tumor cells invaded the dermis and lymph nodes. Although he was postoperatively treated with adjuvant chemotherapies, metastatic skin lesions appeared and spread over his left thigh, rapidly and widely. Tumor cells disseminated along lymph vessels in the dermis and overexpressed HER2 protein. We administered paclitaxel and trastuzumab according to a protocol for HER2-positive metastatic breast cancers. The skin metastasis dramatically decreased during the regimen and a histopathological examination showed that most of HER2-positive tumor cells diminished. Six months later, metastases were found in the central nervous system (CNS), but no other metastases were found in the skin, visceral organs or lymph nodes. Trastuzumab and paclitaxel-combination with the assessment of central nervous system lesions should be considered as an option for the treatment of HER2-positive EMPD. 相似文献

The right subclavian artery was inadvertently punctured during attempted preoperative insertion of a right subclavian venous catheter in a 59-yr-old woman undergoing radical hysterectomy. Large supraclavicular swelling became apparent soon after the arterial puncture. The postoperative chest X-ray obtained approximately 24 h after the catheterization revealed significant elevation of the right hemidiaphragm, which was further augmented on the 2nd to 4th postoperative days; oxygenation was concurrently impaired during these days. It was clinically judged that the hemidiaphragmatic paralysis was responsible for the elevated diaphragm. Both chest roentogenogram and arterial blood gas analyses started to improve on the 5th day, finally returning to normal on the 6th day. It is unlikely that the surgical procedure caused the paralysis, because it dealt only with the lower abdomen. Rather, the attempts at the subclavian venous catheterization probably caused the phrenic nerve paralysis, because the phrenic nerve travels very close to the subclavian vessels. Both the large haematoma formation following the arterial puncture and the time course of the paralysis suggest that compression of the right phrenic nerve by the haematoma, rather than needle trauma, was responsible for the paralysis. 相似文献
