Ghrelin and obestatin are a single gene products and are a multiple functional peptides that regulates energy homeostasis, and food intake. In the present work, we studied the secretion of ghrelin and its co-secreted peptide obestatin in 44 patients with ischemic heart disease with that of 27 healthy matched controls. Here we first conducted using an immunohistochemistry assay to screen whether human salivary glands have any obestatin immunoreactivity. Then, serum and saliva obestatin and acylated ghrelin levels were determined by using Radioimmunoassay. Our immunohistochemical analysis demonstrated that obestatin was localized in the striated and excretory duct of human salivary gland. We also report for the first time that obestatin, like ghrelin, is present in human salivary gland and saliva. No evidence of the role of obestatin or ghrelin saliva levels in the context of ischemic heart disease was found. Salivary ghrelin and obestatin levels are correlated in controls with the blood levels. Determination of salivary values could represent a non-invasive alternative to serum ones that can be useful in clinical practice. [BMB reports 2008; 41(1): 55-61]
Results represented in our study indicate that addition of aprotinin (2 million units) into the prime solution during CPB can reduce lung reperfusion injury.
Empyema is a serious complication of bacterial pneumonia in children. Between July 1992 and July 1998, 53 children aged 7 months to 12 years (mean age, 5.5 years) were treated for empyema complicating pneumonia. After diagnostic thoracentesis, closed tube drainage was carried out with appropriate antibiotic therapy and other treatment strategies such as pleural lavage, intrapleural enzymatic debridement, decortication, or pulmonary resection, according to the effectiveness of drainage and clinical status. There was one death from toxic shock. It was concluded that early decortication in the chronic stage of the disease is a safe and effective treatment modality.
Brucella endocarditis, although a rare complication of brucellosis, is the main case of death attributable to this disease. An atrial septal defect (ASD) presenting with endocarditis in an adult is also extremely rare. We report the case of a male patient who presented with an infective endocarditis and was found to have an ASD. The diagnosis was proven by means of positive serology and isolation of Brucella melitensis from blood cultures and excised vegetation arising from the border of the ASD. The patient was successfully treated by means of excision of the vegetation and specific antibiotic therapy for 3 months.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
