31P NMR spectroscopy was used in conjunction with conventional biochemical techniques to study metabolic abnormalities in normal rats, in rats with CCl4-induced acute liver failure and in rats with paracetamol-induced acute liver failure. Studies were carried out before and after a metabolic challenge in the form of a fructose infusion. Prior to fructose infusion the ATP levels in the groups with acute liver failure were significantly lower than in control rats, despite their having a similar ATP/Pi ratio.

Recently developed application of etched alpha track analysis using an automated image analyser is described. Experiences with this sensitive radiometric technique are reported and discussed.
View Article and Find Full Text PDFA low-intervention policy for Hickman catheter maintenance has been evaluated and found to be safe and cost effective. A simple, lightweight, disposable device has been used for 24-hour ambulatory home infusion. Implementation of this policy as part of a prospective randomized trial of single-agent chemotherapy in advanced breast cancer has demonstrated that slow intravenous infusion reduces the acute toxicity of epirubicin when compared with bolus injection.

Prepubescent male rats were kindled using hourly, suprathreshold stimulations. Two days later the kindled rats and their non-kindled controls received systemic injections of either 6, 10, or 17 mg/kg of kainic acid.

The 5-year survival results for patients with FIGO Stage I disease was 90%; with Stage II disease 60%; with Stage III disease 11% and none survived with Stage IV disease. All the patients, except one (Stage III), with well-differentiated tumours are alive and disease-free, irrespective of the type of treatment they received whereas only one patient out of the 13 who had poorly differentiated tumour is alive and disease-free.

All patients experienced a rapid relief of disease-related symptoms. Following SI the total lymphocyte count (TLC) was markedly reduced in 18 patients.

Results (with a minimum of 5 years follow-up on every patient) favour chemotherapy with a significant increase in the median time to recurrence from 31 to 50 months for all patients (P = 0.04) and from 26 to 49 months for node-positive patients (P = 0.

The profile of breath hydrogen concentration showed an early peak, that occurred soon after ingesting the test meal in 89% subjects. This was followed by a later more prolonged rise in breath hydrogen concentration.

The compounds were isolated from the biological specimen by extraction, the organic phase was evaporated to dryness, and the residue was redissolved in mobile phase [acetonitrile: 0.002 M H2SO4 (1:1)].

Medical and nurse training in palliative care, and pain control in particular, is poor and there is a great shortage of doctors trained in terminal care. Palliative care is detailed, complex care and includes many services both in the hospital and in the community.

Gall stones were identified as the cause of death in only 21 cases (0.26%) but in 291 subjects found to have gall stones or cholecystectomy at necropsy, the mortality was 3.

The hospital mortality was 5 per cent. Subsequent mortality was largely related to the stage of the tumour at presentation and was not higher than that to be expected after an elective resection.

The small bowel transit time of 100 ml of lactulose solution infused at the ligament of Treitz was measured by breath hydrogen excretion in paired studies carried out in 43 healthy volunteers during infusion (1.2 ml/min) of equal volumes (100 ml) of isotonic solutions of either fat emulsion (Intralipid, Prosparol, or Calogen), protein hydrolysate, glucose, or saline into either the jejunum (90 cm from the teeth), ileum (205 cm from the teeth), or colon (350 or 400 cm from the teeth). Ileal infusion of Intralipid or protein hydrolysate resulted in significant delays in small bowel transit time (125 +/- 21 min and 71 +/- 11 min, respectively) compared with infusion of saline (50 +/- 3 min; p less than 0.

It was suggested that this effect was due to the ability of cimetidine to block histamine activation of suppressor lymphocytes and hence allow host defence mechanisms to inhibit tumour growth. In the present studies, C3H/He mice were implanted with a C3H mouse mammary adenocarcinoma on Day 0.

Completed records of the 732 patients initially entered into the trial have now risen from 687 at the last report to 706. The data have been analysed in a manner similar to that adopted previously so as to measure the effects of the two regimes on both tumour and normal tissues, and some additional analyses have now also been made.
