TNF- has been reported to have striking effects on IL-1 release and activation of neutrophils, and to play a pivotal role in the expression of the other pro-inflammatory cytokines. Our data show that endogenously-derived TNF- does play a key role in the renal dysfunction during moderate haemorrhage. These results should be useful to forensic pathologists to explain the pathogenesis of renal dysfunction induced by a moderate haemorrhage and to identify the cause of death where there are no significant morphological changes after moderate haemorrhage. = 5 in each group) by loss of blood through the carotid Imidafenacin catheter or a cardiac puncture, and the blood samples and tissue samples were collected. The blood taken during the early stage of bleeding and pretreated with saline in the haemorrhage group was estimated as pre samples for both sham and haemorrhage groups, and those from the FR group were estimated as pre samples for both the FR and FR + haemorrhage groups. Therefore, the data of pre in the sham and haemorrhage groups are identical, and those in FR and FR + haemorrhage groups are also identical. For the assessment of TNF- mRNA expression changes in the kidney after the bleeding, rats were sacrificed by the method described above, before bleeding and 30 min, 1, 3 and 5 h after the bleeding (= 1 at each time point) and tissue samples were collected. Serum was separated by centrifuging the collected blood at 500 for 20 min and stored at ?80 C, and tissue samples were stored at ?80 C until the assay. “type”:”entrez-nucleotide”,”attrs”:”text”:”FR167653″,”term_id”:”258093044″,”term_text”:”FR167653″FR167653, 1-[7-(4-fluorophenyl)-1,2,3,4-tetrahydro-8-(4-pyridyl) pyrazolo [5,1-c][1,2,4] triazin-2-yl]-2-phenylethanedione sulphate monohydrate (a gift from Fujisawa Pharmaceutical Co.
