INTRODUCTION Since 1970, lengthening of the rectosigmoid has been suspected to be a solitary manifestation of Chagas colopathy. METHODS To test this hypothesis, opaque enema was administered on 210 seropositive and 63 seronegative patients, and radiographs in the anteroposterior and posteroanterior positions were examined blind to the serological and clinical findings. The distal colon was me...

Lower gastrointestinal bleeding (LGIB) in patients with cirrhosis may be associated with life-threatening complications similar to upper GI bleeding (UGIB). The data on LGIB in patients with cirrhosis is surprisingly small. The true incidence, diagnoses, risks of bleeding and results of treatment remain poorly defined, since there are no large epidemiologic studies available. Much of the data a...

Background: The extensive education on contraceptive methods, particularly in rural areas of developing countries, play a pivotal role in preventing of induced abortion. The main purpose of this study was to determine the prevalence and major cause of induced abortion in women in northwestern Iran. Materials and Methods: The hospital documentary of 848 women encountering medical examinations du...

statement of problem: in recent years, numerous reports have been presented in the literature, about gingival overgrowth induced by nifedipine- a calcium antagonist- prescribed for hypertension and certain types of angina. purpose: the purpose of the present study was to investigate the prevalence rate of nifedipine induced gingival hyperplasia in patients and its probable relationship with age...

objective(s): intracerebroventricular injection of orexin-a (hypocretin-1) antagonist has been shown to inhibit stress-induced analgesia. however the locations of central sites that may mediate these effects have not been totally demonstrated. this study was performed to investigate the role of rostral ventromedial medulla (rvm) orexin receptor 1 in stress-induced analgesia (sia). materials and...

knowledge of the orientation of horizontal in situ stresses is important to some areas of oil and gas field development plans. borehole breakouts observed in image logs and drilling-induced fractures are the main parameters for the determination of the stresses’ directions in situ. in this work, the orientations of borehole breakouts were investigated as a function of depth in oil wells a and b...

recognition of relationship between the present day stress state and fractures is very important in fractured reservoirs. fractures that are parallel or oblique to maximum horizontal stress have more tendencies to tensile deformation and tensile deformed fractures will be more permeable. the dalan formation is one of the main gas reservoirs of iran witch most of the production from this formati...
