Evaluation of the therapeutic effect of methylene blue on the liver of rats submitted to ischemia and reperfusion

Acta cir. bras; 33 (12), 2018
Abstract Purpose: To analyze the effect of methylene blue (MB) therapy during the liver ischemia-reperfusion injury (I/R) process. Methods: Thirty-five male Wistar rats were used, (70%) submitted to partial ischemia (IR) or not (NIR) (30%) were obtained from the same animal. These animals were divided ...

Prevention of rocuronium induced mast cell activation with prophylactic oleuropein rich diet in anesthetized rabbits

Acta cir. bras; 33 (11), 2018
Abstract Purpose: The effect of a prophylactic oleuropein-rich diet before anesthesia accompanied by the widely-used steroid-based neuromuscular drug rocuronium on mast cell activation was investigated in the study. Methods: 14 rabbits used in the study. The rabbits in the oleuropein group were given ...

Rivastigmine prevents injury induced by ischemia and reperfusion in rat liver

Acta cir. bras; 33 (9), 2018
Abstract Purpose: To evaluate whether pre-treatment with rivastigmine is able to attenuate the I/R induced lesions in rat liver. Methods: SHAM animals or those submitted to I/R, non-treated or pre-treated with rivastigminine (2mg/kg) either 50 or 15 minutes before ischemia, were used. After I/R proto...

The effect of AST/ALT (De Ritis) ratio on survival and its relation to tumor histopathological variables in patients with localized renal cell carcinoma

Int. braz. j. urol; 44 (2), 2018
ABSTRACT Purpose To assess the relationship between De Ritis (aspartate aminotransaminase [AST]/Alanine aminotransaminase [ALT]) ratio and pathological variables and whether it is an independent prognostic factor. Materials and Methods We analyzed 298 consecutive patients who underwent radical or parti...

The role of oxymatrine in regulating TGF-β1 in rats with hepatic fibrosis

Acta cir. bras; 33 (3), 2018
Abstract Purpose: To investigate whether oxymatrine (OMT) prevents hepatic fibrosis in rats by regulating liver transforming growth factor β1 (TGF-β1) level. Methods: Hepatic fibrosis was induced in rats by thioacetamide (TAA). Blood was collected at the end of week 12 to determine the leve...

Lychee (Litchi chinensis Sonn) peel flour: effects on hepatoprotection and dyslipidemia induced by a hypercholesterolemic diet

An. acad. bras. ciênc; 90 (1), 2018
ABSTRACT Dyslipidemias are associated with the incidence of cardiovascular diseases, obesity, diabetes, hypertension and hepatic steatosis, being the cause of morbidity and mortality. This study investigated the effects of lychee peel flour (PF) on serum levels of total cholesterol (TC), low-density lipo...

Prophylactic application of laser light restores L-FABP expression in the livers of rats submitted to partial ischemia

Clinics; 73 (), 2018
OBJECTIVES: The objective of the present study was to evaluate the protective effect of pre-conditioning treatment with laser light on hepatic injury in rats submitted to partial ischemia using mitochondrial function and liver fatty acid binding protein as markers. METHODS: Rats were divided into four g...

Resultados preliminares de hipotermia tópica do fígado em modelo de isquemia/reperfusão hepática em ratos

Arq. gastroenterol; 54 (3), 2017
ABSTRACT BACKGROUND Ischemia/reperfusion causes organ damage but it is mandatory in hepatic transplantation, trauma and other complex liver surgeries, when Pringle maneuver is applied to minimize bleeding during these procedures. It is well known that liver ischemia/reperfusion leads to microcirculator...

Razão da contagem de plaquetas ao quadrado/diâmetro do baço-aspartato aminotransferase: avaliação de um novo método não-invasivo para a predição de varizes esofágicas

Arq. gastroenterol; 54 (3), 2017
ABSTRACT BACKGROUND - Variceal bleeding has a high mortality among cirrhotics, and screening with endoscopy is indicated at the diagnosis of cirrhosis. Screening with endoscopy implies discomfort, risks and considerable costs. OBJECTIVE - To evaluate platelet count squared/spleen diameter-aspartate a...
