the stimulatory effect of the extract of portulaca oleracea (p. olerace) on β-adrenoceptor of tracheal smooth muscle was examined. to examine β-adrenoceptor stimulatory effect, concentration response curve to isoprenaline was obtained in pre-contracted tracheal smooth muscle in the presence of three concentrations of aqueous-ethanolic extract, propranolol and saline. values of ec50 (the effecti...
Background and purpose: Airway stenosis is one the most dangerous diseases. Anethum graveolens L.(Dill) has anti-spastic effect on smooth muscle. The aim of this study was to investigate the effect of the hydroalcoholic extract of this plant on male rat tracheal smooth muscle contractile activity. Materials and methods: In this experimental study, tracheas of healthy rats were dissected. We in...
Leiomyosarcoma in birds is relatively rare. This tumor as a muscle neoplasm was reported in captive and free ranging birds. Smooth muscle cells may develop to the leiomyosracoma, but splenic smooth muscle trabeculae is most common site of the tumor growth. Although budgerigars have an incidence of neoplastic diseases but smooth muscle tumors were rarely reported in this species. To the best o...
objective: asafoetida (ferula assa-foetida) is known as a valuable remedy for whooping cough, pneumonia, bronchitis in children and asthma treatment in folk medicine. in the present study the relaxant effects of the asafoetida on tracheal smooth muscle of guinea pigs and its probable mechanism(s) were examined. materials and methods: the relaxant effects of three cumulative concentrations of th...
objective(s): the study aimed to investigate the effects of adrenomedullin (adm) and proadrenomedullin n- terminal 20 peptide (pamp) on angiotensin ii (angii)-stimulated proliferation in vascular smooth muscle cells (vsmcs). materials and methods: thoracic aorta was obtained from wistar rats and vsmcs were isolated from aorta tissues and then cultured. in vitro cultured vsmcs were stimulated wi...

less than 5% of prenatal thymoctes express hla-dr before week 12 of gestation. however, the number of hla-dr- positive cells increases during the late second and third trimesters of development. to determine the role of alpha-smooth muscle actin in fetal thymic hla-dr signaling in different stages of development we examined and compared the immunohistochemical expression of alpha-smooth muscle ...
normal 0 false false false en-us x-none ar-sa microsoftinternetexplorer4 sir, leiomyoma is the most common tumor of uterus and female pelvis. leiomyosarcoma almost always arise de novo and almost it doesn’t results from sarcomatous transformation of a leiomyoma. one of the most controversial concepts on the subject of uterine smooth muscle tumors is smooth muscle tumor of uncertain malignant po...
