25. Alterações celulares, moleculares e funcionais de fígados de ratas Wistar tratadas com fatores hepatotróficos / Cellular, molecular and functional alterations in rat liver treated with hepatotrophic factors
Fatores hepatotróficos (FH) possuem a capacidade de promover aumento de massa hepática em ratos e diminuição da fibrose em animais cirróticos. Os FH podem ser importantes nos casos de ressecção e transplantes hepáticos no qual o fígado remanescente necessita de um volume considerável para exercer suas funções após a cirurgia. Objetivou-se neste

26. Modulation of extracellular matrix by nutritional hepatotrophic factors in thioacetamide-induced liver cirrhosis in the rat
Nutritional substances associated to some hormones enhance liver regeneration when injected intraperitoneally, being denominated hepatotrophic factors (HF). Here we verified if a solution of HF (glucose, vitamins, salts, amino acids, glucagon, insulin, and triiodothyronine) can revert liver cirrhosis and how some extracellular matrices are affected. Cirrhosi

27. Study of nuclear texture of Wistar rats after lead poisonig / Estudo da textura nuclear em ratos Wistar intoxicados por chumbo
Lead (Pb) is one of the most important naturally occurring and ubiquitous heavy metals, with toxic effects after acute or chronic exposure on liver, the nervous system, hematopoesis, and, especially the kidneys. The aim was to study the time course of the renal tubular sodium handling during chronic experimental lead poisoning in rats comparing it with the m

28. Glycyrrhizin attenuates endotoxin- induced acute liver injury after partial hepatectomy in rats
Massive hepatectomy associated with infection induces liver dysfunction, or even multiple organ failure and death. Glycyrrhizin has been shown to exhibit anti-oxidant and anti-inflammatory activities. The aim of the present study was to investigate whether glycyrrhizin could attenuate endotoxin-induced acute liver injury after partial hepatectomy. Male Wista

29. The use of light-emitting diodes to stimulate mitochondrial function and liver regeneration of partially hepatectomized rats
The biostimulating effect of laser radiation has been observed in many areas of Medicine. However, there are still several questions to be answered, among them the importance of light coherence in the stimulatory process. In the present study, we used light-emitting diodes (LED) to promote the stimulation of liver regeneration after partial hepatectomy in ra

30. Experimental models of liver regeneration in growing animals. Histological and molecular studies, and evaluation of the effects of immunosuppressants / Modelos de regeneração hepática em animais em crescimento: estudos histológicos, moleculares e avaliação de efeitos de imunossupressores
INTRODUCTION: Partial liver transplantation has been performed in children with increasing frequency, and this emphasizes the importance of the studies of hepatic regeneration and the effects of immunosuppressive drugs on this phenomenon. Liver regeneration is controlled by the balance between cell proliferation and apoptosis (defined as a programmed cell de

31. Hepatic stereology of schistosomiasis mansoni infected-mice fed a high-fat diet
High-fat diets induce weight gain and fatty liver in wild-type mice. Schistosomiasis mansoni infection also promotes hepatic injury. This study was designed to quantify hepatic alterations in schistosomiasis mansoni-infected mice fed a high fat-rich chow compared to mice fed a standard rodent chow, using stereology. Female SW mice fed each either high-fat di

32. Omega-3 and omega-6 fatty acids, dimethylsulfoxide and ternatin on hepatic regeneration and oxidative stress in rats / Ácidos graxos ômega-3 e ômega-6, dimetilsulfóxido e ternatina na regeneração hepática e no estresse oxidativo em ratos
The liver exhibits a remarkable regenerative capacity after tissue damage, including partial hepatectomy. Reactive oxygen species and lipid peroxidation have been implicated as control mechanisms of cellular growth and proliferation. Dimethylsulfoxide (DMSO) and ternatin (TRT), known free radical scanvengers, and the w-3 and w-6 polyunsaturated fatty acids (

33. Effect of hepatotrophic factors on thioacetamide-induced cirrhosis in rats / Efeito do tratamento com fatores hepatotróficos em ratas (Wistar) induzidas experimentalmente à cirrose por Tioacetamida
Cirrhosis is characterized by fibrosis and regenerative nodules, which result in the disorganization of the hepatic architecture, being considered an irreversible situation. The administration of exogenous hepatotrophic factors (EHF) could stimulate hepatic regeneration in hepatocytes cells and reduce the cirrhosis induced in rats. The aim of this work was t

34. Effect of the hepatotrophics factors on liver in rats Wistar (Rattus norvegicus) / Efeitos de fatores hepatotróficos no fígado em ratos Wistar (Rattus norvegicus)
O fígado é um órgão que apresenta grande capacidade regenerativa após injúria. Contudo, é possível desencadear os processos regenerativos sem injúria, pelo uso de fatores hepatotróficos exógenos (FHE) injetados intraperitonealmente. Ainda há controvérsias em relação a essa via de administração. Neste trabalho foram testados dois protocolos d

35. Effect of hyperbaric oxygenation on the regeneration of the liver after partial hepatectomy in rats
The aim of the present study was to assess the influence of hyperbaric oxygenation (HBO) on rat liver regeneration before and after partial hepatectomy. Rats were sacrificed 54 h after 15% hepatectomy, liver and body weights were measured, and serum alanine transaminase (ALT) and aspartate transaminase (AST) activity and albumin levels were determined. The l

36. Hepatic regeneration in african catfish (Clarias gariepinus) after partial hepatectomy. / Regeneração hepática em bagre africano (Clarias gariepinus) após hepatectomia parcial.
The liver is an important organ in studies aimed to the verification of animals reactions to chemical injuries. The partial hepatectomy (PH) is one of the methods that are usually employed in hepatic regeneration experiments. Our objectives in this work were to verify the influence of 30% and 70% PH on the hepatic cells proliferation index as it is measured
