Hypoxic-ischemic lesions of the brain cardiac surgery patients as a leading factor in stroke have been studied. The importance prolonged thrombosis, embolism, which exacerbate general degenerative changes central nervous system is recognized.
 aim research – to study morphological vessels with postoperative on background hypoxic-ischemic complications.
 Materials and methods. Pieces c...
nitric oxide (no) is a small molecule synthesized by most of mammalian cells with diverse biological activities including vasodilatation, host defense and wound healing. impaired wound healing is a common occurrence among diabetics and patients receiving glucocorticoid therapy. on the other hand the application of laser in biomedical area have been increased. thus, the current studies were desi...
abstract previous studies on willingness to communicate (wtc) have shown the influence of many individual or situational factors on students’ tendency to engage in classroom communication, in which wtc has been viewed either at the trait-level or situational level. however, due to the complexity of the notion of willingness to communicate, the present study suggests that these two strands are ...
background: central renin angiotensin system has an important role on the cerebral microcirculation and metabolism. our previous work showed that inhibition of angiotensin converting enzyme (ace) activity prior to induction of ischemia protected the brain from severe ischemia/reperfusion (i/r) injuries. this study evaluated the impacts of post-ischemic inhibition of ace, enalapril, on brain inf...
The effect of pentobarbital and hypothermia on the development of ischemic brain edema was studied in 23 rhesus monkeys undergoing transorbital middle cerebral artery occlusion. Fifteen additional animals served as unclipped controls. Regional cortical cerebral blood flow (rCBF), arteriovenous oxygen content difference (AVDO2), and regional cortical metabolic rate of O2 (rCMRO2) were measured h...
INTRODUCTION Blood pressure (BP) measurement is essential for epidemiological studies and clinical decisions. It seems that tissue characteristics can affect BP results and we try to find edema effect on BP results taken by different methods. METHODS BP of 55 children before open heart surgery were measured and compared according to three methods: Arterial as standard and reference, oscillome...
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 signs...
learning a second or foreign language requires the manipulation of four main skills, namely, listening, reading, speaking, and writing which lead to effective communication. it is obvious that vocabulary is an indispensible part of any communication, so without a vocabulary, no meaningful communication can take place and meaningful communication relies heavily on vocabulary. one fundamental fac...
The histologic description of cerebral ischemia is complex, and within most lesions there are regional variations in degrees of neuronal cell injury, edema, and neuropil disruption. These parameters of tissue injury were analyzed histopathologically in transient and permanent experimental cerebral ischemia in 15 rabbits and the results were spatially correlated with MR images of pre- and postmo...
