Effect of amitriptyline on gastric ulceration   总被引:2,自引:0,他引:2  
Amitriptyline significantly inhibited alcohol, aspirin, indomethacin and cold-restraint stress-induced ulceration. Secretory studies conducted in pyloric-ligated rats revealed that the drug, at the doses employed, significantly reduced total acidity and protein content. However, significant reductions of the gastric volume were only observed at the highest dose of the drug. In another set of experiments, when 50% alcohol (v/v) was administered to the pyloric-ligated rats pretreated with amitriptyline, it was observed that the drug significantly reduced the pH, total acidity and protein content.  相似文献

The so-called learning factor has been disregarded for many years in analyzing the causes of surgical complications and post-operative mortality; it is also the case for OLT. In our center until April 2003, 209 OLT were performed in 196 patients. We evaluated the impact of experience of the transplantation team on the outcomes of liver transplantation. Thirty-four patients died (mortality rate, 16%) and 1-year survival rate, 64%. Mortality rates varied during different periods of observation due to increasing experience of the transplantation team. The causes of mortality were assessed for a series of 34 patients: it was 75% at the beginning of transplantation procedures while recent deaths have not recently exceeded 10% of cases.  相似文献

Abstract: Background : Women's preferences for type of maternity caregiver and birth place have gained importance and have been documented in studies reported from the developed world. The purpose of our study was to identify Syrian women's preferences for birth attendant and place of delivery. Methods : Interviews with 500 women living in Damascus and its suburbs were conducted using a pretested structured questionnaire. Women were asked about their preferences for the birth attendant and place of delivery, and an open‐ended question asked them to give an explanation for their preferences. We analyzed preferences and their determinants, and also agreement between actual and preferred place of delivery and birth attendant. Results : Only a small minority of women (5–10%) had no preference. Most (65.8%) preferred to give birth at the hospital, and 60.4 percent preferred to be attended by doctors compared with midwives (21.2%). More than 85 percent of women preferred the obstetrician to be a female. The actual place of delivery and type of birth attendant did not match the preferred place of delivery and type of birth attendant. Women's reasons for preferences were a perception of safety and competence, and communication style of caregiver. Conclusions : Most women preferred to be delivered by female doctors at a hospital in this population sample in Syria. The findings suggest that proper understanding of women's preferences is needed, and steps should be taken to enable women to make good choices. Policies about maternity education and services should take into account women's preferences.  相似文献
