objective: stevioside is a natural non-caloric sweetener which has been reported to have anti-inflammatory activity.  the aim of  the present study was to examine in vitro and in vivo effects of  stevioside on rats  plasma levels of tumor necrosis factor- α (tnf-α),  interleukin-1β (il-1β), tnf-α and il-1β release from lipopolysaccharide(lps)-stimulated rat peripheral blood mononuclear cells (p...

estrogen (e2) has neuroprotective effects on blood-brain-barrier (bbb) after traumatic brain injury (tbi). in order to investigate the roles of estrogen receptors (ers) in these kind of effects, er-α antagonist (mpp) and, er-β antagonist (phtpp), or non-selective estrogen receptors antagonist (ici 182780) were administered as regulators of cns cytokines levels and neuroinflammation after tbi. m...

objective(s): the present study was aimed to investigate the influence of thoracic epidural blockade on hypoxia-induced pulmonary hypertension in rats. materials and methods: forty eight wistar rats were randomly divided into 4 equal groups, named normoxia hypoxia hypoxia/ ropivacaine and hypoxia/saline. animals were placed in a hypoxia chamber and instrumented with epidural catheters at the th...

objective(s):dependence and tolerance to opioid analgesics are major problems limiting their clinical application. a-terpineol is a monoterpenoid alcohol with neuroprotective effects which is found in several medicinal plants such as myrtus communis, laurus nobilis, and stachys byzantina. it has been shown that some of these medicinal plants such as s. byzantina attenuate dependence and toleran...

background: hepatitis-c infection is a major problem in chronically transfused patients. we compared interferon-α (inf-α) monotherapy with combination of inf-α and amantadine in the treatment of β-thalassemia major patients who were chronically infected with hcv.materials and methods: forty six thalassemia major patients who were chronically infected with hcv were randomly divided into two grou...

inflammatory bowel disease (ibd) is a chronic disease of unknown etiology, in which genetic factors, seem to play an important role in the disease predisposition and course. assessment of tumor necrosis factor (tnf-α) gene polymorphisms in many populations showed a possible association with ibd. considering the genetic variety in different ethnic groups, the aim of the present study was to inve...

background: we aimed to determine the incidence of co-inheritance as well as interaction of sickle cell trait (sct) and α thal /β thal mutations in south and south central of iran. method: we employed a pcr and restriction fragment length polymorphism techniques to confirm diagnosis of sickle cell trait. all subjects were screened for any α/β -thalassemia mutations using a gap-polymerase chain ...

(compositae) with small yellow flowers and several times pinnately divided leaves in worm shape is known for many years in the folk medicine. it has been used to reduce sweating and to stop bleeding. it helps regulation of the menstrual cycle and reduces heavy bleeding and pain. materials and methods: plant material (flower, leaf and stem) was collected in k...

in an endeavor to find a novel series of antihyperglycemic agents, new benzimidazole and pyrimidine derivatives were successfully synthesized efficiently in high yield with high purity, starting from amino acids in the presence of phosphorus oxychloride (pocl3). the synthesized compounds were identified by 1h-nmr, 13c-nmr, ft-ir spectroscopic techniques and elemental analysis. all products were...
