Logáil Isteach / Cláraigh
The effect of hyperthermia on the activity and the messenger RNA levels of ornithine decarboxylase (ODC), which has a rapid rate of turnover in cultured cells, was studied in Ehrlich ascites tumor cells. When the cells were incubated at 42 degrees C, elevation of ODC activity by a change of the

Hyperthermia and polyamine biosynthesis: decreased ornithine decarboxylase induction in skin and kidney after heat shock.

The effect of hyperthermia treatments on ornithine decarboxylase (ODC) induction in mouse tissue was determined both in vitro and in vivo. In vitro, the addition of 12-0-tetradecanoylphorbol-13-acetate (TPA) to adult mouse skin pieces incubated at 37 degrees C in serum-free MEM led to a dramatic

Hyperthermia produced a decrease of ornithine decarboxylase activity in different tissues of adult rats. The fall in ornithine decarboxylase was dependent on time of exposure and temperature. The decay of ornithine decarboxylase activity in liver, brain, kidney, heart, spleen and testes was rather

In the rat, there are marked changes in ornithine decarboxylase activity in the fetuses and reproductive tissues during gestation. Exposure of pregnant rats to moderate hyperthermia (40 degrees C, 60 min) produced a marked decrease (about 80%) of ornithine decarboxylase activity in fetuses, uterus

Nitric oxide (NO) has been shown to be an important mediator of febrile response to lipopolisaccharide (LPS). To clarify the role of different isoforms of NO synthase (NOS) in febrile response to immune challenge, effects of selective iNOS and nNOS inhibitors on fever to LPS were examined in freely

Late onset of symptoms in a 12 1/2-year-old male with ornithine transcarbamylase (OTC) deficiency were associated with unusual histological features in the liver. The patient presented with an acute onset of hyperammonemia and altered mental status after a 2-day prodrome of vomiting and lethargy.

The purpose of these studies was to assess the involvement of nNOS and iNOS inhibitors on stress fever caused by exposure to an open field in freely moving biotelemetered rats. Vinyl-L-NIO (N(5) - (1-Imino-3-butenyl) - ornithine, a neural nitric oxide synthase (nNOS) inhibitor, and aminoguanidine,
Fever was induced in rabbits by i.v. administration of lipopolysaccharide (LPS) or administration of interleukin-1 beta (IL-1 beta) into the organum vasculosum laminae terminalis (OVLT). Intra-OVLT injection of IL-1 receptor antagonist (IL-lra), 1 h before LPS or IL-1 beta injection, inhibited the

Malignant hyperthermia developed in a 4-year-old Thoroughbred horse following 3 hours and 15 minutes of halothane anesthesia, with supplementary succinylcholine. Clinical signs included fever, sweating, hyperventilation, tachycardia, and decreased blood pressure followed by a rapid increase in blood

Hyperthermia caused an immediate decrease of DNA, RNA, and protein synthesis. The latter process was most sensitive. Initiation of DNA synthesis at the transition from G1-to S-phase and at the start of new replication units were inhibited. These effects were responsible for the growth delay of cells

1. Fever was induced in rabbits by administration of Escherichia coli endotoxin (lipopolysaccharide; LPS; 0.001-10 micrograms) into the organum vasculosum laminae terminalis (OVLT). Deep body temperature was evaluated over a period of 7 h. 2. The LPS-induced febrile response was mimicked by
