Effects of different periods of gastric ischemia on liver as a remote organ

Acta cir. bras; 33 (11), 2018
Abstract Purpose: To evaluate the hepatic changes associated with gastric ischemia. Methods: Thirty male rabbits were studied, distributed in 3 groups (n=10). Group 1: ligature and section of the gastric vasculature and removal of the liver after three hours; Group 2: ligature and section of the gast...

Experimental poisoning by Brachiaria decumbens in rabbits

Pesqui. vet. bras; 38 (10), 2018
Brachiaria spp. are important sources of forage for ruminants in Brazil, due to the easy cultivation, good resistance to drought, good adaptation to different soils and low maintenance cost. However, the ingestion of this grass has been related to photosensitization outbreaks in cattle and sheep with sig...

Topical hepatic hypothermia associated with ischemic preconditioning. Histopathological and biochemical analysis of ischemia reperfusion damage in a 24 hour model

Acta cir. bras; 33 (10), 2018
Abstract Purpose: To develop a new 24 hour extended liver ischemia and reperfusion (LIR) model analyzing the late biochemical and histopathological results of the isolated and combined application of recognized hepatoprotective mechanisms. In addition, we used a new stratification with zoning to classi...

Biópsia percutâneas de lesões hepática guiada por ultrassonografia: análise de 171 casos de um único centro oncológico

Arq. gastroenterol; 55 (3), 2018
ABSTRACT BACKGROUND: Though strongly suggestive of metastasis, focal lesions on liver scans of oncological patients require histological confirmation for the prescription of adequate treatment. OBJECTIVE: To evaluate the safety and efficacy of US-guided percutaneous core liver biopsy. METHODS: Desc...

Intravascular and intraparenchymatous hepatic segmentary sclerosis

Acta cir. bras; 33 (9), 2018
Abstract Purpose: To evaluate the morphological effects of injected sclerosing agents into the liver. Methods: This study was performed on twenty dogs, distributed into five groups: Group 1 (n = 5) - control, Group 2 (n = 5) - injection of 50% glucose solution inside hepatic parenchyma and animals fol...

Is the early or delayed remote ischemic preconditioning the more effective from a microcirculatory and histological point of view in a rat model of partial liver ischemia-reperfusion?

Acta cir. bras; 33 (7), 2018
Abstract Purpose: To compare early- and late-effect remote ischemic preconditioning (RIPC) by analysing the microcirculatory, hemodynamic and histological changes in partial liver ischemia-reperfusion of rats. Methods: 60-minute partial liver ischemia followed by 120-minute reperfusion was performed ...

Daño hepatocelular, proteinuria y autoinmunidad: ¿enfermedad multisistémica o coincidencia de enfermedades? Caso clínico

Rev. méd. Chile; 146 (6), 2018
We report a 19 years old male presenting with knee pain, elevated liver enzymes and proteinuria. Further investigation found positive antinuclear and anti-smooth muscle antibodies and a liver biopsy revealed the presence of an autoimmune hepatitis. Treatment with corticosteroids and azathioprine was star...

Capsiate treatment in liver surgeries may compromise its recovery

Acta cir. bras; 33 (5), 2018
Abstract Purpose: To investigate the effects of capsiate treatment on hepatic hyperplasia in partially hepatectomized rats. Methods: The animals were divided into a Capsiate group (CPH), a Capsiate Post-Partial Hepatectomy group (CPPH) and a Partial Hepatectomy Control group (PH). CPH and CPPH animal...

Bioimpedância: nova abordagem para detecção não invasiva da fibrose hepática - estudo piloto

Arq. gastroenterol; 55 (1), 2018
ABSTRACT BACKGROUND: Fibrosis are common structural hepatic change in patients with chronic hepatitis. Liver biopsy is the gold standard for determining the extent of liver fibrosis. Considering the technical difficulties and cost, improvements in non-invasive screening tools are greatly needed. Bioimpe...

Thermal effect of acute and chronic stress on hepatic and renal tissue of the pacific sardine, Sardinops sagax caeruleus (Jenyns, 1842)

Int. j. morphol; 36 (1), 2018
SUMMARY: In the thermal range of the Pacific waters, known for the geographical distribution of Sardinops sagax caeruleus(Jenyns, 1842) (Pacific sardine), could be exposed to a stressing temperature environment with dilated effect. This work examines the liver and kidney of sardines acclimated at differe...
