background: accidents are the second reason for mortality and morbidity in iran. among them, brain injuries are the most important damage. clarification of the effects of brain injuries on different body systems will help physicians to prioritize their treatment strategies. in this study, the effect of pure brain trauma on the cardiovascular system and lungs 24 hours post trauma was assessed. m...

objectives in order to provide a pharmacological profile for some newly synthesized dihydropyridines, we investigated their effects on the isolated rat colon segments and the isolated rat atrium contractility. the tested compounds include alkyl ester analogues of nifedipine, in which the ortho-nitrophenyl group at position 4 is replaced by 2-alkylthio-1-benzyl-5-imidazolyl substituent, and nife...

background : left ventricular (lv) dyssynchrony is a prevalent feature in heart failure (hf) patients. the current study aimed to evaluate the prevalence of inter and intraventricular dyssynchrony in hf patients with regard to the qrs duration and etiology. methods: the available data on the tissue doppler imaging (tdi) of 230 patients with refractory hf were analyzed. the patients were divided...

Rhododendron dauricum L. is an ancient Chinese traditional herb. The pharmacological effects of R. dauricum extract have been shown in chronic tracheitis. The aim of this study was to investigate the cardiovascular effects of Rhododendron dauricum L. flavonoids (RF) on rats and its mechanisms. This study was performed in isolated vascular rings and a rat model of myocardial infarction and isola...

Echocardiography was used to study left ventricular size and contraction in 90 patients with isolated mitral valve disease--47 patients with mitral stenosis, 26 with mixed mitral valve disease and 89 with mitral regurgitation. Left ventricular measurements included the end-diastolic internal dimension (LVIDd), mural thickness (PWTd), an index of circumferential myocardial contraction--fractiona...
