to determine the prevalence of pituitary hormone deficiencies after moderate traumatic brain injury (tbi). we conducted a prospective cohort and included 75 patients with moderate tbi with gcs between 9 and 13 who referred to emergency department of shariati hospital, tehran/iran, during 2004-2007. pituitary hormones were assessed 3 and 6 months after injury. in 3rd month post-injury, 39 cases ...

seizure activity has been proposed to result in the generation of reactive oxygen species (ros), which then contribute to seizure-induced neuronal damage and eventually cell death. although the mechanisms of seizure-induced ros generation are unclear, mitochondria and cellular calcium overload have been proposed to have a crucial role. we aim to determine the sources of seizure-induced ros and ...

fracture of the proximal humerus associated with vascular injury has rarely been reported in children, and only two cases have been reported in the literature. in adults this combination has been reported more frequently. we present the case of a 14 year old boy with proximal humeral epiphyseal separation and axillary artery injury.

introduction: there are several different molecular pathways in tissue damage by ischemic brain injury. the use of antioxidants and free radical scavengers are a matter of attention by some researchers. crocus sativus (saffron) is used previously for protective effects in ischemia state by some researchers. to assess pathologic aspects of neuroprotection of saffron in some susceptible brain are...

conclusions penetrating trauma from wooden fragments provides a diagnostic challenge. a stubborn discharge from a wound must always raise the suspicion of retained fragment. early and appropriate surgical exploration is imperative. introduction in contrast with victims of major trauma, patients who suffer minor injuries receive little specialist input. in most cases, this causes no difficulty, ...

background most of the acid- burns are due to assault or accidental. the epidemiology of burns is diverse across the world and within a country. we evaluated the epidemiology and outcome of acid-burns in tertiary health care center in tehran, iran. methods this study was retrospective descriptive among patients referred for acid-burn injury that was done in a referral burn care center in tehran...

tomato is one of the sensitive fruits to mechanical impacts and physical tensions. the mostmechanical damages arise from handling which results in reducing tomato quality. in this study,impact energy effect has been studied in 3 different levels 0, 0.14 and 0.25 j by a pendulum impactapparatus, on changes of physicochemical properties of tomato, hybrid variety shiva f1, includingripening factor...

organ damage after reperfusion of previously viable ischemic tissues is defined as ischemia/reperfusion injury. the pathophysiology of ischemia/reperfusion injury involves cellular effect of ischemia, reactive oxygen species and inflammatory cascade. protection against ischemia/reperfusion injury may be achieved by preconditioning or postconditioning. in this review, we discuss basic mechanisms...
