primary sarcomas of the kidney are exceptional. among renal sarcomas, leiomyosarcoma is the most common histologic subtype amounting to 50-60% of all cases. the tumor usually arises from either the renal capsule or smooth muscle tissue in the renal pelvic wall. in this paper, we report a patient with leiomyosarcoma of the kidney presented with non-specific abdominal pain and a palpable mass. hi...

the seed of croton tiglium l. (sct) is a well known folk medicine. in china, it has used to treat gastrointestinal disorders, intestinal inflammation, rheumatism, and so on. previous studies established its purgative and inflammation properties. in addition, the effects of essential oil of sct on intestinal transit and gastrointestinal tract has been studied. in the present study, we evaluated ...

conclusions these results showed an inhibitory effect for the extract of asafetida on muscarinic receptors of tracheal smooth muscle. results the ec50 obtained in the presence of higher concentration of the extract muscle was significantly higher compared to saline (p < 0.01). the maximum responses to methacholine in the presence of higher concentration of the extract (10 mg/ml) was significant...

bronchial asthma is the common chronic inflammatory disease and is characterized by chronic airway inflammation, airway remodeling, and airway hyperreactivity (ahr). aim of this study was to investigate the effects of mitochondrial atp-sensitive potassium channels (mitokatp) on the proliferation and secretion of human airway smooth muscle cells (hasmcs). hasmcs were treated with the serum from ...

objective(s): in the present study, the effect of tissue incubation with propranolol on functional antagonism of zataria multiflora boiss (z. multiflora) at muscarinic receptors of tracheal smooth muscle was examined.  materials and methods: the effects of three concentrations of aqueous-ethanolic extract, 10 nm atropine, and saline on muscarinic receptors were tested on incubated tracheal smoo...

Up to date, there are four pharmacologically characterized subtypes of muscarinic receptors (M1, M2, M3 and M4). In our study we have investigated muscarinic receptor subtypes in smooth muscle layers of human stomach. Isolated preparations of longitudinal and circular muscle layers from human stomach were used. Acetylcholine, bethanechol, carbachol, pilocarpine and AHR -602 produced concen...

Introduction: We did this study because there were a few studies about aorto-branch junction. Methods: Four light microscope and electron microscope study, the abdominal aorta, renal&nbsp;artery, and the adjoining right and left renal arteries were dissected out from 4 neonate dogs. Results: Based on the results, there is only one cell type in the tunica intima of endothelium in&nbsp;both art...
