Aquaporin 4 (AQP4) is a widely distributed membrane protein, which is found in glial cells, ependymocytes and capillary endothelial cells in the brain, and particularly in the choroid plexus. AQP4 is a key regulator of water metabolism, and changes in its expression following brain injury are associated with pathological changes in the damaged side of the brain; however, the effects of brain in...
Background and Objective: One of the major side effects of cerebral ischemia is the water content enhancement in brain tissues which leads to mortality enhancement. Recently, therapeutic strategies have been focusing on preconditioning mechanisms. Erythropoietin as a glycoprotein hormone with anti-inflammatory and antioxidant effects on brain may be effective on brain edema reduction. Mate...
BCNU wafers are a form of interstitial chemotherapy that is expected to improve the survival of patients with malignant glioma. However, their adverse events, especially brain edema, sometimes cause significant clinical symptoms. In this study, we performed a volumetric analysis of brain edema after the implantation of BCNU wafers and reported on the clinical course, and exacerbation factors of...
Objective(s) Opioid abuse is still remained a major mental health problem, a criminal legal issue and may cause ischemic brain changes including stroke and brain edema. In the present study, we investigated whether spontaneously withdrawal syndrome might affect stroke outcomes. Materials and Methods Addiction was induced by progressive incremental doses of morphine over 7 days. Behavioral si...
Introduction: Development of brain edema following focal cerebral ischemia exacerbates primary ischemic injury. Blood brain barrier (BBB) opening is an important part of edema named as vasogenic brain edema. In this study, quantitative alterations of BBB permeability is experimentally evaluated using transient focal cerebral ischemia in the rat. Methods: Two groups of male rats (ischemic and sh...
Introduction: Milliary metastasis to the brain is absolutely rare and there are few reports in the medical literature. These reports were cases with calcified and well known origin milliary metastases. Case Report: In this paper we report a 42-year-old man with milliary metastasis to cerebral and cerebellar hemispheres and brain stem from an unknown etiology without any mass effect edema or ...
Brain edema is a potentially fatal pathological state that occurs after brain injuries such as stroke and head trauma. In the edematous brain, excess accumulation of extracellular fluid results in elevation of intracranial pressure, leading to impaired nerve function. Despite the seriousness of brain edema, only symptomatic treatments to remove edema fluid are currently available. Thus, the dev...

Objective(s): Brain edema is one of the most serious causes of death within the first few days after trauma brain injury (TBI). In this study we have investigated the role of Shilajit on brain edema, blood-brain barrier (BBB) permeability, intracranial pressure (ICP) and neurologic outcomes following brain trauma. Materials and Methods: Diffuse traumatic brain trauma was indu...
