Ice received 3 series of images, including CT, PET, and a merge of CT and PET. The location of the liver is labeled by a dotted line where the crosssectioned images were obtained. (B) These images are cross-sections of the livers. At 8, 72 and 168 hr after treatment with Gh-rTDH, the uptake of 18 F-FDG in livers decreased in proportion to the dosage of Gh-rTDH. (C) The 18F-FDG uptake value was calculated using the ROI (liver/muscle, semiquantification) in each mouse. Higher doses of toxin indicated lower levels of 18F-FDG uptake. In the animal infection models, the 18F-FDG uptake levels 25033180 were clearly lower in mice that were fed (D) G. hollisae or (E) E. coli-TOPO-tdh than those fed (F) E. coli-TOPO. These decreases were in proportion to the levels of 1418741-86-2 site bacteria in the treatment. doi:10.1371/journal.pone.0056226.gincreased in a dose-dependent manner. The acute hemolytic status in vivo results in acute anemia, which would exacerbate tissue hypoxia and organ hypoperfusion. Therefore, septicemia caused by Vibrio species with the tdh gene might be more critical than that caused by the Vibrio species without the tdh gene. Clinically, the hepatotoxicity might be caused via hemolysis. However, the pathological findings revealed that the hepatic injury was mainly located at the periportal areas, and the injury was not diffused. It is suspected that the major etiology is toxin absorption and injury to the liver via the venous return of the portal system. Clinical 18F-FDG PET/CT scans have been reported as excellent tools to survey organ metabolism in small animals [30]. Damage in the liver caused by Gh-rTDH can be demonstrated by blood withdrawal and liver biopsy. However, the conditions of recovery and organ metabolism in living animals were difficult to analyze. Therefore, 18F-FDG PET/CT scans were performed forour assessment. We noted that the uptake of 18F-FDG in the livers decreased in proportion to the MedChemExpress 76932-56-4 administered dosages of Gh-rTDH, which indicate that the hepatic damage in the animals was dosedependent. In other non-hepatic organs, damage was not obvious. After exposure to Gh-rTDH, the uptake of 18F-FDG gradually increased in trend. We suggest that the livers could finally reconstruct from the destruction of Gh-rTDH exposure, and these liver cells had undergone repair and proliferation via increasing their uptake of glucose, which is well-known as an unavoidable material in metabolism. The metabolism of glucose in the livers damaged by Gh-rTDH almost recovered to a normal range in the 72nd hour after exposure to TDH. Furthermore, the metabolism of glucose crossed the normal range in the 168th hour after exposure to Gh-rTDH, and the recovery was more predominant in mice treated with low dosages than in those treated with a high dosage of Gh-rTDH. The level of glucose uptake crossing the normalHepatotoxicity of Thermostable Direct Hemolysinrange noted that the metabolism of glucose was notably robust in these damaged livers in addition to ongoing strong recovery. According to our findings from the liver biopsies, the construction might be mainly located in the periportal area, which has been labeled as a major location of glucose and amino acid metabolism [26?8]. Therefore, the construction in the periportal area might contribute to the high level of 18F-FDG intake in the liver during the recovery stage. Overall, this finding might provide strong evidence indicating that the reconstruction of liver continues for at least one week after a sing.Ice received 3 series of images, including CT, PET, and a merge of CT and PET.
