Two permanent cell lines, A7 and A10, were established from ascitic effusions obtained from patients with ovarian carcinomas. Cell growth characteristics, karyotyping, and morphological examinations by light and electron microscopy revealed the neoplastic nature of the lines. Desmosomes were found indicating an epithelial origin. Both lines showed G6PD type B. Ascites seemed to be a good source for cultivation of ovarian carcinoma cells. 相似文献

The fracture of the penis is an uncommon injury that is defined as a rupture of the tunica albuginea of the corpus cavernosum. We present our experience in 9 cases admitted to our department between 1989 and 1998. Most of the cases were caused by traumatism during sexual intercourse. Clinical presentation and physical examination were enough to make the diagnosis. The treatment was surgery in all cases, with evacuation of the hematoma and reconstruction of the rupture with absorbable suture. The result about penile function and curvature was excellent in all cases. There was no cases of penile incurvation nor erectil disfunction. CONCLUSIONS: In our experience, surgical management of the penile fracture has good results, with no erectil disfunction, nor penile incurvation. 相似文献

Objective
The purpose of this study was to evaluate the antioxidant status of plasma vitamin E and plasma and intracellular coenzyme Q10 in children with type 1 diabetes.Method
This case–control study was conducted on 72 children with type 1 diabetes and compared to 48 healthy children, who were age, sex, and ethnicity-matched. The diabetic children were divided according to their glycosylated hemoglobin (A1c %) into two groups: poor and good glycemic control groups. All children underwent full history taking, clinical examination, and laboratory measurement of complete blood count, A1c %, plasma cholesterol, triglycerides, and vitamin E levels and coenzyme Q10 levels in plasma, erythrocytes, and platelets.Results
Children with poor glycemic control showed significantly higher plasma vitamin E, coenzyme Q10, triglycerides, low-density lipoproteins, waist circumference/height ratio, cholesterol levels, and lower high-density lipoproteins and platelet coenzyme Q10 redox status in comparison to those with good glycemic control and the control group (p < 0.05). Plasma coenzyme Q10 showed a positive correlation with the duration of type 1 diabetes, triglycerides, cholesterol, vitamin E, and A1c %, and negative correlation with the age of the diabetic group (p < 0.05). The platelet redox status showed a negative correlation with the A1c % levels (r = ?0.31; p = 0.022) and the duration of type 1 diabetes (r = ?0.35, p = 0.012).Conclusion
Patients with type 1 diabetes, especially poorly controlled, had elevation of plasma vitamin E and coenzyme Q10 levels and decreased platelet redox status of coenzyme Q10, which may be an indicator of increased oxidative stress. 相似文献996.

Context In May 2002, the World Health Organization and the United Nations Children's Fund recommended that the formulation of oral rehydration solution (ORS) for treatment of patients with diarrhea be changed to one with a reduced osmolarity and that safety of the new formulation, particularly development of symptomatic hyponatremia, be monitored. Objective To measure the rates of symptomatic hyponatremia during treatment of patients with diarrhea with reduced osmolarity ORS. Design, Settings, and Patients A phase 4 trial conducted at the Dhaka hospital (December 1, 2002-November 30, 2003) and Matlab hospital (February 2, 2003-January 31, 2004) of the International Centre for Diarrhoeal Disease Research Bangladesh: Centre for Health and Population Research, Dhaka, Bangladesh. All patients admitted with uncomplicated watery diarrhea were treated with the newly recommended ORS and monitored. Patients developing neurological symptoms (seizure or altered consciousness) were transferred to the special care ward for treatment and investigated to identify the cause of the symptoms. Patient records of the Dhaka hospital were reviewed during the previous year when the old ORS formulation was used. Intervention Reduced osmolarity ORS. Main Outcome Measure Incidence rate of symptomatic hyponatremia in a 1-year period. Results A total of 53 280 patients, including 22 536 children younger than 60 months, were monitored at the Dhaka and Matlab hospitals. Twenty-four patients, none older than 36 months, developed seizures or altered consciousness associated with hyponatremia, with an overall incidence rate of 0.05% (95% confidence interval [CI], 0.03%-0.07%) at the Dhaka hospital and 0.03% (95% CI, 0.01%-0.09%) at the Matlab hospital. During the previous year, 47 patients at the Dhaka hospital had symptoms associated with hyponatremia, for an estimated incidence rate of 0.10% (95% CI, 0.07%-0.13%). The reduction in the rates was statistically significant (odds ratio, 0.50; 95% CI, 0.29-0.85; P = .009). Conclusion The risk of symptoms associated with hyponatremia in patients treated with the reduced osmolarity ORS is minimal and did not increase with the change in formulation. 相似文献

PURPOSE: To study the processes involved in mediating conjunctival remodelling in vernal keratoconjunctivitis (VKC) by investigating the expression of integrin receptors, epidermal growth factor receptor (EGFR), vascular endothelial growth factor (VEGF), transforming growth factor-beta(TGF-beta), basic fibroblast growth factor (bFGF), platelet-derived growth factor (PDGF), and Ki67 antigen, which is a marker for cell proliferation. METHODS: Conjunctival biopsy specimens from 16 patients with active VKC and nine control subjects were studied by immunohistochemical techniques using monoclonal and polyclonal antibodies directed against the integrin alpha3 and alpha6 subunits, EGFR, VEGF, TGF-beta, bFGF, PDGF, and Ki67 antigen. The phenotype of inflammatory cells expressing growth factors was examined by double immunohistochemistry. RESULTS: In the normal conjunctiva, very weak immunoreactivity was observed for EGFR and VEGF in epithelial cells, and for alpha3 and alpha6 integrin subunits on basal epithelial cells, and on vascular endothelial cells in the upper substantia propria. There was no immunoreactivity for the other antibodies. In VKC specimens, strong staining for alpha3 and alpha6 integrin subunits was observed on the membranes of basal and suprabasal epithelial cells, and all vascular endothelial cells. Immunoreactivity for Ki67 antigen was observed in the nuclei of the basal and suprabasal epithelial cells. Strong immunoreactivity was observed for EGFR in the deeper layers of the epithelium, and for VEGF in all epithelial cells. Inflammatory cells expressing EGFR, VEGF, TGF-beta, bFGF, and PDGF were noted in 8, 9, 11, 10, and 10 specimens, respectively. The majority of inflammatory cells expressing growth factors were eosinophils (45+/-4%) and monocytes/macrophages (35+/-4%). CONCLUSIONS: Chronic conjunctival inflammation in VKC is associated with increased staining of alpha3, and alpha6 integrin subunits, EGFR, VEGF, TGF-beta, bFGF, and PDGF that might mediate conjunctival remodelling. 相似文献

This study was designed to evaluate the health and economic benefits of a workplace vaccination programme against influenza funded by the employer. Employees of a Malaysian petrochemical plant volunteered to take part in this prospective, non-randomised, non-placebo-controlled study. Demographic and health information, including influenza-like symptoms, sick leave and post-vaccination adverse events were collected via questionnaires. Cost-benefit analyses were performed from the employer's perspective. Results: A total of 1,022 employees took part in the study, with 504 choosing to be vaccinated against influenza, and 518 remaining unvaccinated. The rate of influenza-like illness (ILI) was lower among vaccinated (8.13%) than non-vaccinated subjects (30.31%). Fever and respiratory symptoms were associated with all ILI cases. ILI-related sick leave was taken by 58.54% of vaccinated employees with ILI and 71.34% of non-vaccinated employees with ILI. Vaccination was financially beneficial, with the employer saving up to US dollar 53.00 per vaccinated employee when labour costs only were considered. Savings rose to up to US dollar 899.70 when the operating income of each employee was also considered. Workplace vaccination of healthy adults against influenza had a clear impact on ILI rates, absenteeism and reduced productivity in this Malaysian company. The health benefits translated into financial benefits for the employer, with cost savings significantly outweighting the costs of the vaccination programme. 相似文献

Based on several surveys during 1997-2005 and visits of a medical team to Eruani village, Laksham upazila, Comilla district, Bangladesh, the arsenic contamination situation and consequent clinical manifestations of arsenicosis among the villagers, including dermatology, neuropathy, and obstetric outcome, are reported here. Analysis of biological samples from patients and non-patients showed high body burden of arsenic. Even after eight years of known exposure, village children were still drinking arsenic-contaminated water, and many of them had arsenical skin lesions. There were social problems due to the symptoms of arsenicosis. The last survey established that there is a lack of proper awareness among villagers about different aspects of arsenic toxicity. The viability of different options of safe water, such as dugwells, deep tubewells, rainwater harvesting, and surface water with watershed management in the village, was studied. Finally, based on 19 years of field experience, it was felt that, for any successful mitigation programme, emphasis should be given to creating awareness among villagers about the arsenic problem, role of arsenic-free water, better nutrition from local fruits and vegetables, and, above all, active participation of women along with others in the struggle against the arsenic menace. 相似文献

In the Middle East, the major sources of lead exposure have been leaded gasoline, lead-contaminated flour from traditional stone mills, focal exposures from small battery plants and smelters, and kohl (blue color) in cosmetics. In 1998-2000, we measured blood lead (PbB) levels in children 2-6 years of age in Israel, Jordan, and the Palestinian Authority (n = 1478), using a fingerstick method. Mean (peak; percentage > 10 microg/dL) PbB levels in Israel (n = 317) , the West Bank (n = 344), Jordan (n = 382) , and Gaza (n = 435) were 3.2 microg/dL (18.2 ; 2.2%) , 4.2 microg/dL (25.7; 5.2%), 3.2 microg/dL (39.3; < 1%) , and 8.6 microg/dL (> 80.0; 17.2%), respectively. High levels in Gaza were all among children living near a battery factory. The findings, taken together with data on time trends in lead emissions and in PbB in children in previous years, indicate the benefits from phasing out of leaded gasoline but state the case for further reductions and investigation of hot spots. The project demonstrated the benefits of regional cooperation in planning and carrying out a jointly designed project. 相似文献
