Vardenafil is a selective phosphodiesterase-5 inhibitor used for erectile dysfunction treatment. The hepatoprotective role of vardenafil against acute hepatitis is not reported yet. Hence, this study aims to explore the protective role of vardenafil against concanavalin A (Con A) induced acute liver injury. Mice were pretreated with vardenafil (0.17 mg/kg/day) for seven consecutive days, and then subjected to a single IV injection of Con A. The results demonstrated that the vardenafil pretreatment significantly reduced the elevated serum levels of transaminases and alkaline phosphatase...

Acute kidney injury (AKI) is associated with high perioperative mortality. A series of AKI research breakthroughs are worth mentioning. First, in 2003, serum and urine biomarkers specific to AKI were identified. These biomarkers have contributed to early detection, prevention, and treatment of AKI. In 2004, AKI severity was defined with the Risk, Injury, Failure, Loss, and End-stage kidney disease (RIFLE) criteria, which was developed by the International Consensus Conference Workgroup of the Acute Dialysis Quality Initiative...

Vildagliptin is a potent, orally active inhibitor of dipeptidyl peptidase-4 (DPP-4) for the treatment of type 2 diabetes mellitus. It has been reported that vildagliptin can cause hepatic dysfunction in patients. However, the molecular-mechanism of vildagliptin-induced liver dysfunction has not been elucidated. In this study, we employed an expression microarray to determine hepatic genes that were highly regulated by vildagliptin in mice. We found that pro-inflammatory S100 calcium-binding protein (S100) a8 and S100a9 were induced more than 5-fold by vildagliptin in the mouse liver...

BACKGROUND: It has been observed that patients with liver dysfunction need lower dose anesthetic compared patients with normal liver function. The minimum amount of volatile anesthetic to achieve an optimal depth of anesthesia for these patients is still unclear. In this study, Minimum alveolar concentration (MAC) of the sevoflurane was determined using an electric stimulation and the effect of severity of liver dysfunction on the MAC was observed in cirrhotic patients. METHODS: Thirty patients undergoing upper abdominal surgery were divided into the following groups: group N (normal liver function), group A (Child-Pugh grade A) and group B (Child-Pugh grade B-C)...

Liver failure is a frequent and serious complication that causes morbidity and mortality in haematopoietic stem cell transplantation (HCT) recipients. Liver dysfunction in these patients can be related to infectious causes, most common viral hepatitis. We report a case of disseminated acyclovir-resistant herpes simplex virus (HSV) infection following HCT that led to acute liver failure and death. Although rare, HSV hepatitis leads to high morbidity and mortality and should be considered in the differential diagnosis of HCT recipients with marked elevation of hepatic transaminase...

Low-grade systemic inflammation in adipose tissues or liver, is an important etiologic factor in insulin resistance. LPS is an important element causing such metabolic inflammation, and intestinal flora is considered a major source of systemic LPS. We studied changes of intestinal microbiota associated with high-fat diet (HFD) that causes insulin resistance and metabolic stress. 16S rRNA gene sequencing showed that HFD significantly decreased the abundance of a mucin-degrading bacterium Akkermansia muciniphila compared to control diet...

Reactive oxygen species (ROS) have been shown to have a role in inflammation. We investigated whether Forsythia suspensa extract (FSE) could exert its antioxidant potential against lipopolysaccharide (LPS)-induced inflammatory liver injury in rats. Rats were orally fed FSE once daily for 7 consecutive days prior to LPS (Escherichia coli, serotype O55:B5) injection. LPS treatment caused liver dysfunction as evidenced by massive histopathological changes and increased serum alanine aminotransferase and aspartate aminotransferase activities which were ameliorated by FSE pretreatment...
