| Abstract The aim of this study was to assess the hepatotoxicity cases described in the literature, attributed to the consumption of Herbalife(r) products, and to determine whether a causal relationship exists between the reported cases of liver injury and the use of these products. A literature search was performed on the PubMed, LILACS and PAHO databases. Seven publications reporting a total of 53 cases of hepatotoxicity linked to the use of Herbalife(r) products were retrieved. All of the studies lacked sufficient information to some degree, whether related to patients' history, concomitant use of medication and/or other compounds (including alcohol), observations on interrupted use (dechallenge), results found with markers, viral serology and... |

| Venom of the South American rattlesnake, Crotalus durissus terrificus (Cdt), presents myotoxic and neurotoxic outcomes, but reports on its effects on the liver are scarce. This study examined the hepatotoxicity resulting from Cdt venom administration (100, 200 and 300 µg/kg) in male Wistar rats. Animals were studies at 3, 6, 9 and 12 hours after venom injection. The hepatotoxicity was assessed through serum levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (AP), gamma glutamyl transferase (GGT), bilirrubin and also by histopathological evaluation. All the different concentrations of Cdt venom resulted in increased levels of hepatic enzymes, when compared with the control group, except for the 100 µg/kg dose,... |

| The aim of this study was to investigate the effect of bark extract Bathysa cuspidata (BCE) in the reconstitution of hepatic parenchyma and stroma after dysfunction induced by the CCl4. Liver lesions were induced by intraperitoneal administration of CCl4 (1 mL/kg) every 48 h for 12 days. The animals were treated with B. cuspidata extract (BCE) administered by gavage for another 12 days. Forty-nine rats were randomized into seven treatment groups with seven animals receiving CCl4, BCE (200, or 400 mg/kg) and the vehicle DMSO alone, or in different combinations. The extract alone showed no evidence of hepatic toxicity. In general, rats acutely exposed to CCl4 without the treatment with BCE presented high ALT and AST serum levels and high tissue content of... |

| Vancomycin (VCM) is indicated in combat against Gram-positive infections, but it is not considered a first-choice drug because of its adverse effects. It is believed that oxidative stress is the primary mechanism of endothelial injury and the consequent VCM toxicity, which varies from phlebitis to nephrotoxicity. Moreover, dose recommendations, dilution, rates and types of infusion are still controversial. The aim of this study was to determine the effect of different VCM dilutions in endothelial, liver and kidney injuries by biochemical parameters and histopathological analysis. Wistar rats were randomly divided into six groups and subjected to femoral vein cannulation for drug administration. Control groups received 0.9 ml of saline and the others... |

| ABSTRACT This study aimed to evaluate the teratogenic and hepatotoxic potential of the usnic acid encapsulated into PLGA-microspheres. In total, 12 female Wistar rats in pregnancy were randomly distributed in the control group (n= 6) that received 1.0 mL of physiological solution and treatment group (n= 6) that received 25 mg/kg of encapsulated usnic acid by oral administration. All females were euthanized at day 20 of pregnancy and their fetuses were removed and analyzed. During the pregnancy was observed a reduction in weight gain. There was no difference in serum transaminases levels analyzed as well as any difference in liver weight in both groups. The histomorphometric analysis of the liver from the treatment group revealed an increase in number of... |

| This study aimed on evaluating the possible effects of tetracycline administered to rats on the tenth day of pregnancy, on kidney and liver development of their offspring. The liver showed vacuolization, necrosis, inflammation and sinusoidal dilatations, more evident in the newborn. Mitosis, early increase of Kupffer cells population and hipertrophy of hepatocytes with greater synthesis of glycogen were present on the tenth and twentieth days of life. The kidney showed slight tubular vacuolizations and necrosis, more proeminent in the newborn, as well as signs of tubular regeneration on the tenth and twentieth days. These results suggested that the organs studied went through several transitory morphological changes during development but presented signs... |

| Nevirapine-based therapy is associated with increased frequency of adverse events among HIV-infected pregnant women. The aim of this article was to evaluate the incidence of adverse effects in HIV-infected women who started nevirapine during pregnancy. A retrospective study was performed in our center between January 2003 and December 2006 analyzing all women prescribed nevirapine during pregnancy. Women presenting any risk factor for hepatotoxicity were excluded from the analysis. Patients were divided into two groups according to the presence or absence of adverse effects, and a correlation to CD4 counts was performed. Liver function abnormality was graded according to the Division of AIDS toxicity guidelines. A total of 170 women initiated nevirapine... |

| Anti-tuberculosis drug-induced hepatitis (ATD- induced hepatitis) has been linked to polymorphisms in genes encoding drug metabolizing enzymes. N-acetyltransferase 2 (NAT2), cytochrome P450 2E1 (CYP2E1) and glutathione S-transferase (loci GSTM1 and GSTT1) are involved in the metabolism of isoniazid, the most toxic drug for the treatment of tuberculosis (TB). This study was designed to determine the frequency and to evaluate whether polymorphisms at CYP2E1, GSTM1 and GSTT1 genes are associated with drug response, as well as to identify clinical risk factors for ATD-induced hepatitis. A total of 245 Brazilian patients undergoing treatment for TB were genotyped using polymerase chain reaction and restriction fragment length polymorphism and sequencing... |

| BACKGROUND: The liver is an important organ for its ability to transform xenobiotics, making the liver tissue a prime target for toxic substances. The carotenoid bixin present in annatto is an antioxidant that can protect cells and tissues against the deleterious effects of free radicals. In this study, we evaluated the protective effect of bixin on liver damage induced by carbon tetrachloride (CCl4) in rats. RESULTS: The animals were divided into four groups with six rats in each group. CCl4 (0.125 mL kg-1 body wt.) was injected intraperitoneally, and bixin (5.0 mg kg-1 body wt.) was given by gavage 7 days before the CCl4 injection. Bixin prevented the liver damage caused by CCl4, as noted by the significant decrease in serum aminotransferases release.... |
