It causes progressive lesions as steatosis, fibrosis, necrosis, and apoptosis. Mechanisms of action such as direct hepatotoxicity, reduced immunity, inflammation and increased intestinal permeability are involved.<a class="elsevierStyleCrossRefs" href="#bib0005">1</a>–<a class="elsevierStyleCrossRef" href="#bib0015">3</a> Acetaldehyde, a major toxic metabolite, is responsible for trans-differentiate hepatic stellate cells (HSC) into collagen-secreting myofibroblasts (COLL) to perisinusoidal space, making the sinusoids to be highly capillarized. The acetaldehyde is converted to the acetate by aldehyde dehydrogenase (ALDH), producing reduced NAD (NADH). The increase in the ratio NADH/NAD promotes the synthesis of fatty acids (steatosis), reduces the activity of the Krebs cycle and leads to accumulation of acetyl CoA and acetaldehyde. The Microsomal Ethanol Oxidation System (MEOS) is another EtOH converter dependent on cytochrome P-4502E1 and important in the genesis of alcoholic liver disease (ALD) by producing reactive oxygen species (ROS) associated with tissue damage.<a class="elsevierStyleCrossRef" href="#bib0020">4</a> Steatosis may progress to perivenular fibrosis<a class="elsevierStyleCrossRef" href="#bib0025">5</a> and degeneration of hepatocytes.<a class="elsevierStyleCrossRef" href="#bib0030">6</a> The liver is at the same time, the main EtOH-metabolizing organ and the target of its deleterious effects.<a class="elsevierStyleCrossRef" href="#bib0035">7</a> The absence of parental care (maternal separation) represents a stress factor during early life and potentiate the risk for development of depression- and anxiety-like symptoms during adulthood.<a class="elsevierStyleCrossRef" href="#bib0040">8</a> Experiencing trauma in childhood may not only increase the risk of these neurological disorders, but also alter the effectiveness of the treatment under certain conditions.<a class="elsevierStyleCrossRef" href="#bib0045">9</a> The environment provided by the mother in the postnatal period produces psychological and neurobiological impacts on animals and humans.

It is well known that stress and EtOH intake share some effects on liver tissue such as oxidative damage and inflammation. Adverse experiences in childhood are associated to the vulnerability in developing abusive EtOH ingestion through alterations of HPA axis.<a class="elsevierStyleCrossRef" href="#bib0040">8</a> EtOH consumption reduces anxiety while it simultaneously activates the stress-related hormones through the HPA axis with the intensity and duration of glucocorticoid response being strictly dependent on the amount of EtOH consumed.<a class="elsevierStyleCrossRef" href="#bib0065">13</a> Therefore, this study was designed to test whether there is interaction of MS and EtOH consumption on the structure of UCh rat liver.Material and MethodsRat models and treatmentsThe UChA strain rats (rats selected for low voluntary 10% EtOH consumption with brother X sister mating, Wistar) and UChB (rats selected for high voluntary 10% EtOH consumption with brother X sister mating, Wistar) strains were obtained from the Anatomy Department Animal Facility at the Institute of Bioscience, Campus of Botucatu (IBB/UNESP). Twelve couples of each strain were used with two experimental groups (Control and Maternal Separation-MS). Adult females, after fertilization were accompanied during the gestational period. The birth date was stipulated as day zero, with the litter standardized with eight pups by selecting the largest number of males as possible. Each group used ten rats for 120 days of experimentation. The rats were kept in polypropylene cages measuring 40 x 30 x 15 cm with laboratory-grade pine shavings as bedding, under controlled conditions of brightness (12 h light and dark cycle), temperature (20 to 25 °C) with water and standard pellet food (Nuvital®) ad libitum. All animal experiments were performed under a protocol approved by the local ethical committee (IBB/UNESP) and in accordance with the Brazilian Animal Protection Legislation. Four groups were formed (<a class="elsevierStyleCrossRef" href="#t0005">Table 1</a>).<elsevierMultimedia ident="t0005"></elsevierMultimedia>Hyperresponsivity induction by MSPups were separated daily from their mothers, during the SHRP, between four and 14 days-old, always at the same time. During MS, the pups were isolated for 4 h in a cage containing eight subdivisions, one for each pup. The rats were kept in a neighboring room at 30 °C and over 50% humidity. Afterwards, the pups were brought back to their mothers that had been removed from their respective cages before meeting their litter again. Control pups were not separated from their mothers and were only subjected to the standard procedures used for laboratory animals. Rats were handled by only one researcher during the whole experiment. The animal facility room was isolated as much as possible from external noise. The researcher’s hands were washed in running water, dried and rubbed on the wood of the litter cage roof in order to eliminate smells that could make mothers reject their offspring. The male pups were housed in boxes with a minimum of two and a maximum of four rats after weaning to 21 days, avoiding stress by social isolation. The male pups were individualized and received standard procedures during their development.Selection of EtOH consuming ratsAt 65 days-old, UChA and UChB rats started receiving a 10% (v/v) EtOH solution and water ad libitum for 15 days, being the bottles alternated periodically (water and EtOH) positions in the cage during the measurements. Rats that presented the highest (UChB) and the lowest (UChA) EtOH consumption were selected to the experiment. Both EtOH (10%) and water were provided ad libitum to UChA and UChB rats until the end of the experiment (120 days) (<a class="elsevierStyleCrossRef" href="#f0005">Figure 1</a>). UChA and UChB strains were selected and standardized according to Mardones and Segovia-Riquelme.<a class="elsevierStyleCrossRef" href="#bib0070">14</a><elsevierMultimedia ident="f0005"></elsevierMultimedia>Biological materialsAll biological samples were harvested at 120 days of age under two distinct procedures: five rats were undergoing euthanasia by decapitation for evaluation of blood plasma hormonal concentrations. Five rats were submitted to transventricular infusion with Bouin’s solution after anesthesia. The liver was collected to histological routine for morphometric and stereological analyses, weighed and fixed by immersion in Bouin’s solution during 24 h. After washing in the increased ethanol series, the tissue fragments were dehydrated and embedded in paraplastic (Oxford Labware, St. Louis, USA). The blocks were sectioned at four mm thickness (LEICA 2145 microtome) and stained with Hematoxilin-Eosin (HE) (focal necrosis, microvesicular steatosis and sinusoid’s diameter) and Picrosirius red (COLL fiber bundle under polarized light microscope, μm<a class="elsevierStyleCrossRef" href="#bib0010">2</a>, AxioVision, Zeiss, Hamburg, Germany). The slides were analyzed and captured by digital photomicroscope Axiophot II (Zeiss). The area occupied by COLL was measured around vessels with approximately 50 mm diameter. The microvesicular steatosis was evaluated by the ratio of positive cells and the total hepatocytes. The focal necrosis was quantified by the amount of necrotic foci. The diameter of hepatic sinusoid was expressed in im (software AxioVision Zeiss, Hamburg, Germany). In all measurements we utilized 10 microscopic fields (x 400) per rat.ImmunohistochemistrySections of liver tissue (n = 10/group) were deparaffinized in xylene based on the areas previously identified during the morphological characterization. Thereafter, tissue sections were microwaved while immersed in 0.01 M sodium citrate buffer, pH 6.0, for 3 x 5 min for antigen retrieval. After blocking endogenous peroxidase activity with 3% hydrogen peroxide and 97% MeOH, the tissues were incubated in 3% bovine serum albumin (BSA) for 1 h to eliminate non-specific binding. Subsequently, liver tissues were incubated with primary polyclonal antibodies diluted in PBS (1:100), anti-a-smooth muscle Actin (Anti-aSMA, Abcam, Cambridge, MA, UK), anti-transforming growth factor beta (Anti-TGF-Beta, Abcam, Cambridge, MA, UK) and mouse monoclonal anti-proliferating cell nuclear antigen (Anti-PCNA, Dako, CA, USA 0879) at 4 °C overnight. After washed in PBS, sections were incubated with Novolink Polymer Detection Systems (Leica Microsystems, Wetzlar, Germany) for 1 h. Then, the slides were reacted with chromogen diaminobenzidine (DAB; Sigma, St. Louis, MO, USA) for 5 min. Apoptotic cells were quantified by TUNEL assay through terminal deoxynucleotidyl transferase (TdT) using the FragELTM DNA Kit (Calbiochem, La Jolla, CA, USA). The apoptotic nuclei were identified with DAB. After these procedures, the sections were counterstained with Harris hematoxylin and photographed on a Zeiss Axiophot light microscope (Zeiss, Hamburg, Germany). The apoptosis and mitosis were expressed by the ratio of stained and non-stained nuclei. The quantification of TGF-Beta was made by counting the number of immunoreacted stellate cells and the SMA was determined by calculating the size of the area marked (Zeiss AxioVision, Hamburg, Germany). All measures were made in 10 microscopic fields (X 400) per rat.Hormonal assaysAfter decapitation, trunck blood samples were obtained into heparinized tubes to verify Testosterone (T), 5α-di-hidrotestosterone (DHT), and Corticosterone (CORT) hormone levels using ELISA kits (Maia, BioChem Immuno Systems, Italia SPA). The LH and FSH plasma concentrations were achieved by double antibody radioimmunoassay method (RIA, Harbor-UCLA, USA). All samples were run in the same assay for each hormone to avoid interassay variations.Biochemical assayThe biochemical levels: total cholesterol (TC), high density lipoprotein-cholesterol (HDL-C), low density lipoprotein-cholesterol (LDL-C), very low density lipoprotein-cholesterol (VLDL-C), and triglycerides (TG) were measured using the spectrophotometric method according to the manufacturer’s (Bioclin, Belo Horizonte, MG, Brasil). Results were expressed as mg.dL-1.Statistical analysesKolmogorov-Smirnov test was used to determine parametric distribution of data. Two-tailed Student’s t-tests were used for comparisons involving only two groups. All data were presented as mean ± standard deviation (SD) and P < 0.05 was considered significant.<a class="elsevierStyleCrossRef" href="#bib0075">15</a>ResultsEthanol intake, body and liver weight<a class="elsevierStyleCrossRef" href="#t0010">Table 2</a> shows increase of body and liver weight in the UChBMS.<elsevierMultimedia ident="t0010"></elsevierMultimedia>Focal necrosis, microvesicular steatosis and sinusoidal capillarie<a class="elsevierStyleCrossRef" href="#t0015">Table 3</a> shows decrease of focal necrosis (<a class="elsevierStyleCrossRef" href="#f0010">Figures 2C, 2D</a>) and sinusoidal capillarie diameter (<a class="elsevierStyleCrossRef" href="#f0010">Figures 2G, 2H</a>) in the UChBMS, and increase of microvesicular (<a class="elsevierStyleCrossRef" href="#f0010">Figures 2A, 2B</a>) steatosis in the UChAMS.<elsevierMultimedia ident="t0015"></elsevierMultimedia><elsevierMultimedia ident="f0010"></elsevierMultimedia>Immunohistochemistry<a class="elsevierStyleCrossRef" href="#t0020">Table 4</a> shows an increase in the area of perilobular vessels by the presence of a-SMA (<a class="elsevierStyleCrossRef" href="#f0010">Figures 2I, 2J</a>) and in the number of immunostaining HSC (<a class="elsevierStyleCrossRef" href="#f0010">Figures 2K, 2L</a>) in the UChBMS.

The interaction of MS decreased necrosis, possibly due to increased programmed cell death<a class="elsevierStyleCrossRef" href="#bib0095">19</a>.EtOH alters the metabolic pathways to increase the activity of nuclear receptors related to the synthesis and release of lipoproteins and decrease the β-oxidation of fatty acids, leading to steatosis with progressive loss of hepatocytes.<a class="elsevierStyleCrossRef" href="#bib0095">19</a> The UChA rats increased microvesicular steatosis associated with MS, so it is more sensitive to variations in EtOH intake.The sinusoid vascular congestion has direct dependence of MS and EtOH amount. The sinusoidal dilatation suggests elimination strategy of hepatic metabolites. Alterations on sinusoidal flow or small increases in portal pressure, may cause circulatory stasis<a class="elsevierStyleCrossRef" href="#bib0100">20</a> that may increase hypoxia and aggravate the liver injury since this is the place of biotransformation activity related to EtOH metabolism.

We designed to test whether there is interaction of maternal separation (MS) on the ethanol-preferring rats liver structure. The UCh rat pups were separated daily from their mothers during the stress hyporesponsive period (SHRP), between four and 14 days-old, always at the same time for four hours in a cage containing eight subdivisions, one for each pup. Subsequently, rats that presented the highest (UChB) and the lowest (UChA) ethanol (EtOH) consumption were selected to the study. Both UChB and UChA rats received 10% (v/v) EtOH and distilled water ad libitum until the end of the experiment (120 days-old). The liver was collected to histological routine for morphometric and stereological analyses, and immunohistochemistry.Results. There was an interaction of MS and EtOH on the liver: increased liver mass, peritubular vessels, stellate cell numbers, steatosis and cell death, decreased necrosis, sinusoidal capillary diameters and cell proliferation. While there was a decrease in FSH, testosterone and 5a-di-hidrotestosterone, and increasing corticosterone and cholesterol.Conclusions. There is interaction of MS and EtOH on the liver structure, dependent on the amount of EtOH intake.
