background: hepatic ischemia/reperfusion injury (i/ri) is a multifactorial pathophysiologic process which can lead to liver damage and dysfunction. this study examined the protective effect of dexamethasone on the gene expression of endothelial nitric oxide synthase (enos) and endothelin-1 (et-1) and on the liver tissue damage during warm hepatic i/r. methods: a total of 32 male wistar rats was...

Sustained downgaze mostly occurs in association with lesions affecting the dorsal midbrain. We report sustained downgaze in a patient with hepatic encephalopathy. The sustained downgaze existed for seven more days after she regained her consciousness. The persistent downgaze even after regaining full consciousness indicates localized pretectal dysfunction rather than diffuse encephalopathy as t...

A hallmark of the disease state following severe burn injury is decreased liver function, which results in gross metabolic derangements that compromise patient survival. The underlying mechanisms leading to hepatocyte dysfunction after burn are essentially unknown. The aim of the present study was to determine the underlying mechanisms leading to hepatocyte dysfunction and apoptosis after burn....

Non-alcoholic fatty liver disease (NAFLD) is the hepatic manifestation of the metabolic syndrome. Most morbidity associated with the metabolic syndrome is related to vascular complications, in which endothelial dysfunction is a major pathogenic factor. However, whether NAFLD is associated with endothelial dysfunction within the hepatic vasculature is unknown. The aims of this study were to expl...

A 56-year-old woman with Graves' disease presented with the complaints of diarrhea and palpitations. Physical examination and laboratory data revealed hypothermia and signs of mild hyperthyroidism, heart failure, hepatic dysfunction with jaundice, hypoglycemia, and lactic acidosis. The patient was diagnosed as having developed the complication of thyroid storm in the absence of marked elevation...

Backgrounds. VitB6 deficiency has been associated with a number of adverse health effects. However, the effects of VitB6 in metabolic syndrome are poorly understood. Methods. VitB6 (50 mg/kg/day) was given to Apoe (-/-) mice with hkdigh-fat diet (HFD) for 8 weeks. Endothelial dysfunction, insulin resistance, and hepatic lipid contents were determined. Results. VitB6 administration remarkably in...

Mitochondrial diabetes is characterized by diabetes and hearing loss in maternal transmission with a heteroplasmic A3243G mutation in the mitochondrial gene. In patients with the mutation, it has been reported that hepatic involvement is rarely observed. We demonstrated a case of hypertrophic cardiomyopathy and hepatic failure with mitochondrial diabetes. To clarify the pathogenesis we analyzed...

Advanced cancer in the setting of liver dysfunction poses a dilemma for physicians, as many cancer chemotherapeutic agents undergo hepatic metabolism. Most cytotoxic drugs have a narrow therapeutic index, and the administration of chemotherapy to patients with liver impairment results in complicated safety issues. We present a concise review of cancer chemotherapy dosing in the setting of liver...

Capecitabine (Xeloda) is a rationally designed oral, tumor-selective fluoropyrimidine carbamate aimed at preferential conversion to 5-fluorouracil (5-FU) within the tumor. Because capecitabine is extensively metabolized by the liver, it is important to establish whether liver dysfunction altered the pharmacokinetics of capecitabine and its metabolites. This was investigated in 14 cancer patient...

I N initial clinical trials of organ transplanta.tion, F~. 5~ has shown remarkable immunosuppressive activity. The drug is very lipophilic. metabolized in the liver, and predominantly eliminated through the bile. 2 Hepatic dysfunction was expected to alter the pharmacokinetics of FK 506. Hepatic dysfunction is also known to alter the absorption of lipid soluble drugs. 3 This is related to the l...
