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)
A highly regulated crosstalk exists between the immune and neuroendocrine systems with the altered immune responses in stress-related disorders being a valid example of this interaction. The Wister Kyoto (WKY) rat is an animal model with a genetic predisposition towards an exaggerated stress response and is used to study disorders such as depression and(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)
