This study was designed to determine whether nutritional folate depletion exerts hepatic oxidative stress in relation to elevated plasma homocysteine. To mimic various extents of folate depletion status in vivo, male Wistar rats were fed an amino acid-defined diet containing either 8 (control), 2, 0.5, or 0 mg folic acid/kg diet. After a 4-wk feeding(More)
1. In the present study, we used a low dose of propofol (5 mg/kg per h) to investigate its effects on the pro-inflammatory cytokines (tumour necrosis factor (TNF)-alpha, interleukin (IL)-1beta and IL-10) and changes in nitric oxide (NO) following lipopolysaccharide (LPS) for a period of 12 h in conscious rats. 2. Experiments were designed to induce(More)
Lipopolysaccharide is strongly associated with septic shock, leading to multiple organ failure. It can activate monocytes and macrophages to release proinflammatory mediators such as tumor necrosis factor-alpha (TNF-alpha), interleukin-1 beta (IL-1 beta), and nitric oxide (NO). The present experiments were designed to induce endotoxin shock by an(More)
Sepsis is the leading cause of death for intensive care patients. Lipopolysaccharide (LPS) administration to animals under anesthesia is a strategy for the study of uncontrolled release of proinflammatory cytokines. Anesthetics have been indicated that they can specially affect immune responses, such as the inflammatory response. Pentobarbital is an(More)
Nitric oxide (NO), tumor necrosis factor-alpha (TNF-alpha), and interleukin 1-beta (IL-1beta) are postulated to play a key pathophysiologic role during sepsis. In this study, we examined the time course of inducible NO synthase (iNOS) mRNA expression and the plasma TNF-alpha and IL-1beta in lipopolysaccharide (LPS)-treated conscious rats. The hemodynamic(More)
Effects of chronic ingestion of 2 levels of alcohol on selenium (Se) utilization were determined in initially Se-depleted rats. Male weanling rats were fed ad lib a Se deficient (0.012 mg/kg) basal diet for 4 weeks and then were meal-fed low or marginally adequate Se in the form of high Se yeast for 4 weeks. During Se repletion, ethanol, which replaced(More)
1. In the present study, we investigated the effects of the inducible nitric oxide (iNOS) inhibitors S-methylisothiourea (SMT) and l-N(6)-(1-iminoethyl)-lysine (l-Nil) on endotoxin-induced acute lung injury (ALI), as well as the associated physiological, biomedical and pathological changes, in anaesthetized Sprague-Dawley rats and in rat isolated perfused(More)
Pulmonary edema (PE) may occur with enterovirus 71 (EV71) infection. We monitored arterial pressure (AP) and heart rate (HR) in patients with EV71 infection and analyzed the variability of AP and HR. Sympathetic activity, AP, and HR increased with respiratory stress. Thereafter, parasympathetic activity increased with decreases in AP and HR. The lungs(More)
Alcohol intoxication and psychiatric medication overdoses, including antidepressants, are common emergency room events. Heavy alcohol and antidepressant exposure are able to induce changes in cytokines disturbing normal physiology. We examined the inflammatory and physiological effects of selective serotonin reuptake inhibitor (SSRI) medication after heavy(More)
