We examined for myocardial ischemia induced by continuous inhalation of fenoterol in children with severe acute asthma. Thirty children with severe acute asthma were evaluated for signs of myocardial ischemia when treated with 0.5 mg kg dose (maximum 15 mg) of inhaled fenoterol for one hour. The heart rate was measured before and after inhalation. Cardiac enzymes (creatine kinase, creatine kina...

BACKGROUND AND PURPOSE Perfusion imaging sequences are an important part of imaging studies designed to provide information to guide therapy for treatment of cerebrovascular disease. The purpose of this study was to perform a meta-analysis of the medical literature on perfusion imaging to determine its role in clinical decision making for patients with acute cerebral ischemia. MATERIALS AND M...

BACKGROUND Epidemiology data for lower-extremity arterial thromboembolism (LET) are limited and may result from either acute limb ischemia or an acute exacerbation of critical limb ischemia. Given marked changes in both diagnosis and therapy over the last 2 decades, we hypothesized that this time period would have witnessed reductions in both the incidence and in-hospital mortality of LET. ME...

Summery. The aim — analysis of preliminary experience treatment COVID-19-associated acute lower limbs ischemia in elderly and senile patients.
 Materials methods. We examined 48 patients (age 60- 84 years). First group 16 with ischemia, second 32 chronic limb without coronavirus infection. .
 Results discussion. group’s had extended blood clotting time (more than 13-15 min). Other ind...

in the current study, effects of acute short term administration of fructose on cardiac arrhythmias and myocardial infarction size following ischemia/reperfusion were investigated in isolated rat heart. the hearts were subjected to 30 min zero flow global ischemia followed by 120 min reperfusion. in the control group, the hearts were perfused by normal drug free krebs-henseleit (k/h) solution t...

Cardiovascular diseases, particularly coronary artery disease (CAD), continue to occupy a prominent position with regard morbidity and mortality in the modern world. Acute myocardial infarction (AMI), main pathology resulting from acute ischemia, persists significant rates both developed developing countries, despite advances established protocols aimed at reperfusion. Diagnosis of AMI, as well...

renal ischemia-reperfusion (ir) contributes to the development of acute renal failure (arf). oxygen free radicals are considered to be principal components involved in the pathophysiological tissue alterations observed during renal ir. the purpose of this study was to investigate the combination effect of melatonin (mel) and erythropoietin (epo), which are a potent antioxidant and anti-apoptoti...

Our findings demonstrate the pivotal importance of caspase-3 in regulating renal microvascular dysfunction, fibrogenesis, and long-term impairment after acute kidney injury induced by ischemia-reperfusion injury. Furthermore, this study establishes predominant role peritubular capillary integrity as a major contributor to progressive dysfunction

BACKGROUND AND PURPOSE Inflammation and hypercoagulability contribute to the development of acute cerebral ischemia. Both can be mediated by the CD40 system. This study investigated whether the CD40 system and related mediators are upregulated in patients with transient ischemic attack (TIA) or stroke. METHODS Seventeen patients with TIA, 60 patients with complete stroke, and 15 control subje...
