Following a single injection of 7.5 x 10(7) U kg-1 of human recombinant tumour necrosis factor-alpha (TNF-alpha) to female NMRI mice, marked hypoglycaemia was observed within a 2 h period, accompanied by a severe depletion of liver glycogen and a drop in rectal body temperature when compared with pair-fed controls. There was no alteration in plasma alanine,(More)
A comparison has been made of the cachectic effects produced by the transplantable murine adenocarcinoma of the mouse colon (MAC16) with tumour necrosis factor-alpha (cachectin). Tumour necrosis factor-alpha (TNF-alpha) produced a dose-related weight reduction that was accompanied by a decrease in both food and water intake. The degree of weight loss was(More)
A comparison has been made of the weight loss produced by tumour necrosis factor (TNF) (cachectin) with that produced by a restricted food and water intake (pair-fed controls), and by mitozolomide, a drug which in toxic doses induces weight loss with a similar decrease in nutrient and water intake. When administered as two separate injections over a 24 h(More)
Visceral hypersensitivity and an increased response to stress are two of the main symptoms of irritable bowel syndrome. Thus efforts to develop animal models of irritable bowel syndrome have centred on both of these parameters. The anticonvulsant gabapentin, which is widely used as an analgesic agent, also reduces anxiety. No data exists to our knowledge of(More)
Visceral pain is a significant and prevalent feature of several disorders including the functional gastrointestinal disorder, irritable bowel syndrome (IBS). Treatment strategies are limited and often unsatisfactory which has opened up new research avenues into the aetiology of visceral pain. This research has led to an increased appreciation of the role of(More)
Administration of either tumour necrosis factor alpha (TNF-alpha) or 16,16-dimethylprostaglandin E2 (PGE2) to female NMRI mice caused a decrease in body weight accompanied by a reduction in both food and water intake and a decrease in carcass water content. A single injection of TNF-alpha caused an enhanced production of PGE2 by spleen cells from treated(More)
