BACKGROUND Excess production of nitric oxide (NO) by the inducible NO synthase (iNOS) has been implicated in the pathophysiology of septic shock. Using methaemoglobin (metHb) and the stable NO metabolite nitrate as markers of NO formation, we assessed the effect of iNOS blockade by aminoguanidine (AG) on hypotension and NO formation in endotoxaemic rats.

This study demonstrated that chronic aspartame consumption in rats can lead to altered T-maze performance and increased muscarinic cholinergic receptor densities in certain brain regions. Control and treated rats were trained in a T-maze to a particular side and then periodically tested to see how well they retained the learned response. Rats that had(More)
Lymphocele is a complication which will be familiar to the gynaecological surgeon, particularly the oncologist. It is also well recognised in association with urological pelvic surgery and renal transplantation. Occurrence of lymphocele has been described in relation to surgery in a wide variety of other areas including the mediastinum, axilla, neck, aorta(More)
OBJECTIVE To investigate whether the location and extent of the CT hyperdense artery sign (HAS) at presentation affects response to IV alteplase in the randomized controlled Third International Stroke Trial (IST-3). METHODS All prerandomization and follow-up (24-48 hours) CT brain scans in IST-3 were assessed for HAS presence, location, and extent by(More)
A randomised phase III trial was conducted to assess the role of interferon-alpha (INFalpha) 2a as maintenance therapy following surgery and/or chemotherapy in patients with epithelial ovarian carcinoma. Patients were randomised following initial surgery/chemotherapy to interferon-alpha 2a as 4.5 mega-units subcutaneously 3 days per week or to no further(More)
BACKGROUND AND OBJECTIVES It has been suggested that the potency of epidural morphine might be explained by spinal metabolism to the active and potent metabolite morphine-6-glucuronide (M6G). The main objective of this study was to describe the early pharmacokinetics of epidurally administered, morphine with special attention to the appearance of the(More)
Four cytology sampling methods were compared in 1063 patients referred for colposcopy with a recent abnormal smear. A dyskaryotic smear of any grade was considered a positive result, though comparisons were limited to cases with a subsequent biopsy confirming CINII or III. There were no differences between the abilities of any of the four methods to detect(More)
BACKGROUND It is unclear whether activation of the inducible nitric oxide synthase (iNOS) increases or decreases the extravasation of plasma. METHODS Chloralose anaesthetised male Wistar rats received E. coli lipopolysaccharide (LPS), 3 mg kg-1 i.v., or the corresponding volume of saline, 3 or 5 h before the end of the experiment. Mean arterial pressure(More)
BACKGROUND It is generally maintained that protein and fluid are lost from the circulation under septic conditions. The role played by an increased production of nitric oxide, by the inducible nitric oxide synthase (iNOS), in this process is unclear. METHODS Chloralose anaesthetised male Wistar rats received E. coli lipopolysaccharide (LPS), 3 mg kg(-1)(More)
