Background and Objective: Inflammatory pseudotumor  is a lesion composed of proliferating spindle cells with mixed inflammatory infiltrates. Some authors have proposed the name inflammatory myofibroblastic tumor as a proper descriptive term rather than the vague inflammatory pseudotumor. The aim of this study was to verify the myofibroblastic origin of spindle cells in idiopathic orbital inf...

smooth muscle tumors rather benign or malignant can arise wherever the muscular tissue presents but cutaneous leiomyoma is one of the rare benign tumors of the which even the diagnostic criteria from the malignant type of the tumor is still in doubt. this study was aimed to compare the subtypes of cutaneous leiomyoma from different histologic aspects in order to find unique criteria for better ...

introduction: thymol has negative ionotropic effect on heart and has direct effect on calcium release from sarcoplasmic reticulum. some of the herbal plants just like carum copticum consist of thymol. the postganglionic neurons of the gastrointestinal parasympathetic system are located mainly in the myenteric and submucosal plexuses. stimulation of these parasympathetic nerves causes general in...

Sphingolipid metabolism was examined in guinea-pig airway smooth muscle cells stimulated by platelet-derived growth factor (PDGF) and 4β-phorbol 12- myristate 13-acetate (PMA), as mitogens and bradykinin (BK) as non-mitogen. Stimulation of the cells by PMA and PDGF for 60 min. at 37°C induced the following changes in sphingolipid metabolites: in cells prelabeled with PH] palmitate, a 1.2 f...

Functionally contracting smooth muscle is an essential part of the engineered intestine that has not been replicated in vitro. The purpose of this study is to produce contracting smooth muscle in culture by maintaining the native smooth muscle organization. We employed intact smooth muscle strips and compared them to dissociated smooth muscle cells in culture for 14 days. Cells isolated by enzy...

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...
