Sponge-induced exudate from the rat and saline extracts of normal rat liver and rat liver damaged in situ by dimethylnitrosamine have been assayed for putrescine, spermidine and spermine levels. The three physiological oligoamines have been examined for anti-inflammatory activity by the
Isoprenaline and salbutamol, two beta-adrenoceptor agonist drugs, and 3-isobutyl-methyl xanthine and thioacetamide have been shown to be anti-inflammatory. Their mode of action is probably due to an increase in the levels of the three endogenous substances adenosine-3',5'-cyclic monophosphate and
OBJECTIVE
To explore the influence of exogenous putrescine and cadaverine on pro-inflammatory factors in the peripheral blood of rabbits.
METHODS
Forty ordinary adult New Zealand rabbits were divided into saline, necrotic tissue homogenate (NTH), putrescine, and cadaverine groups according to the
Background
Polyamines are essential for cell growth and beneficial for intestinal maturation. To evaluate the effects of
putrescine on alleviating intestinal atrophy and underlying molecular mechanisms, both
in vivo feeding trial and
in vitro cell culture were
Histamine and putrescine (a precursor of polyamines) are formed by histidine decarboxylase (HDC) and ornithine decarboxylase (ODC), respectively. Within a few hours after injection of a lipopolysaccharide (LPS) into mice, HDC is induced in the liver, spleen, lung and bone marrow, and ODC is induced
The regulation of putrescine/polyamine export out of the cell was investigated during activation of monocytic-leukemic RAW 264 cells with LPS and IFN-gamma. The RAW 264 cells exported putrescine constitutively at a significant rate into the culture medium. This export process appeared to be
In human periodontal disease, there may be periods of exacerbation and remission. Definition of the homeostatic mechanisms in the periodontium may therefore be important in understanding the natural history of this disorder. The polyamines are biologically active amines involved in the regulation of
Polyamines (putrescine, spermidine and spermine) are aliphatic amines that are produced by the action of ornithine decarboxylase (ODC) in a rate-limiting and protein kinase C (PKC)-regulated step. Because high levels of polyamines are found in the synovial fluid of arthritic patients, the aim of the
Transglutaminase (TGase) activities were measured in rat tissues 1-7 days after intraperitoneal injection of saline or lipopolysaccharide (LPS) and in the cells and media from pre-confluent human fibroblasts cultured for two days in the presence or absence of LPS. epsilon (gamma-Glutamyl)lysine and
In the past decade, there has been growing public concern for the human health effects of exposure to environmental pollutants. Ozone (O3) is one of the most reactive components of photochemical air pollution. Despite extensive investigations by many laboratories on the functional, biochemical, and
Biogenic amines (BA) are a broad group of biologically active substances, the presence of which in the human body can provide important diagnostic information for many various pathologies, including chronic inflammation. In this work, a capillary electrophoresis (CE) hyphenated with tandem mass
The single nucleotide polymorphism (SNP) rs1893217 within the gene locus encoding PTPN2 represents a risk factor for inflammatory bowel disease (IBD). Our previous work demonstrated reduced PTPN2 activity and subsequently increased inflammatory signaling upon presence of SNP rs1893217. The effects of dietary proteins given as whole proteins (WP) or as a peptide hydrolysate (PH) on growth, nitrogen retention, and small bowel adaptation were assessed using two groups of male Wistar rats. Measurements were made 18, 42, and 66 h after acute inflammation induced by subcutaneous
Bacterial lipopolysaccharide (LPS) is an effective activator of the components of innate immunity. It has been shown that polyamines and their metabolic enzymes affect the LPS-induced immune response by modulating both pro- and anti-inflammatory actions. On the other hand, LPS causes changes in
