From February to November 2006, 100 central venous catheters (CVCs) were collected from patients admitted consecutively to the medical and surgical intensive care units (ICUs) of Colombo South Teaching Hospital (CSTH), who had temperature >38°C. Before removal of the venous catheter, two blood culture samples were collected, one through the central venous line and the other from a peripheral ve...

Klumbies & Kleinsorge (1950) and Fox & Fox (1969) recorded blood pressure, heart rate and respiratory changes during ejaculation elicited by masturbation and natural coitus. Jakubowski (1966) reported that a rise in the heart rate occurred and Wierzcho\l=s'\(1970) observed a rise in blood pressure, heart rate and respiratory rate during copulation in the boar. According to W\l=o'\jcik(1969), th...

Introduction: The use of cord stem cells, as a cell source for bone marrow reconstruction in patient under hematopoietic stem cell transplantation is enhancing. The amount of CD34+cells collected from cord blood compared to peripheral blood and bone marrow are less, but their collectionprocesure is easier. Delay in freezing has negative effect on cells surveillance and reduce their ability in ...

BACKGROUND Critical macromolecules of cells such as DNA are in exposure to damage of free radicals that induced from the interaction of ionizing radiation with biological systems. Selenium and vitamin-E are natural compounds that have been shown to be a direct free radical scavenger. The aim of this study was to investigate the radioprotective effect of selenium and vitamin-E separately and syn...

BACKGROUND Extracorporeal circulation used during coronary artery bypass grafting triggers systemic inflammatory response with neutrophil activation which adversely affects ischaemic/reperfused myocardium. One method of myocardial protection during cardiac surgery is the use of blood cardioplegia. Its protective effect is related to cardiac cooling and metabolism reduction, oxygen supply from e...

BACKGROUND Previous study has demonstrated the efficacy of hemodialysis in reducing blood glutamate levels. The purpose of the present study is to investigate whether peritoneal dialysis (PD) may be effective in lowering blood glutamate levels, which may serve as a potential tool for improving neurological function after brain injury. METHODS Two liters of dialysis solution were infused over ...

Salivary oxidative stress markers represent a promising tool for monitoring of oral diseases. Saliva can often be contaminated by blood, especially in patients with periodontitis. The aim of our study was to examine the impact of blood contamination on the measurement of salivary oxidative stress markers. Saliva samples were collected from 10 healthy volunteers and were artificially contaminate...
