“…Na análise estatística, os resultados não relevaram correlação significativa entre os níveis de ferro sérico e o hábito etilista dos universitários (p > 0,05), em ambas as coletas (C1, r = -0,286; C2, r = -0,085). Embora os resultados não sejam significativos entre esses dois parâmetros, alguns estudos evidenciam que o consumo de álcool aumenta a absorção de ferro pelo organismo (SABINO et al, 2010;CIROLINI, 2010). Em contrapartida, os mesmos autores apontam que a redução desse mineral ocorre quando o indivíduo apresenta deficiência nutricional, que associada à prática do etilismo, diminui sua absorção pelo organismo, fatores que podem culminar em anemia.…”

O estudo avaliou os níveis de ferro sérico correlacionando com IMC, hábitos alimentares e etilismo em estudantes universitários de um Curso de Ciências Biológicas, Ituiutaba, MG, com idade média de 22 ± 2,88 anos. Os participantes responderam questionário semiestruturado auto responsivo online e foram submetidos a coleta de sangue para análise clínica. Os resultados revelaram que apenas 10% dos estudantes avaliados tinham níveis de ferro sérico abaixo do recomendado. Não houve correlação significativa entre os níveis de ferro sérico e o hábito etilista dos universitários ou o IMC, apesar de outros estudos evidenciarem que hábitos não saudáveis, como o consumo de álcool e a má alimentação, influenciam a absorção do ferro. Sendo assim, os resultados obtidos são importantes para nortear outros estudos, além de ações de caráter extensionista a fim de melhorar a qualidade de vida desses jovens universitários.

“…Furthermore, alcoholism is associated with atherosclerosis and thromboembolism. [13][14][15][16][17][18]34,35,37,38 Previous studies have shown that alcohol consumption tends to increase the stability of atheromatous plaques in large arteries, such as the aorta and the common iliac and femoral arteries, but this benefit has not been demonstrated in small and medium-sized arteries, including the coronary and hepatic arteries. [39][40][41][42] In the present study, the arterial wall defects of two groups of patients who underwent liver transplantation because of severe cirrhosis, the first because of alcoholism and the second because of other causes, were compared.…”

Objective We aimed to characterize the relationship between severe chronic alcoholism and hepatic arterial wall disorders in humans. Methods We obtained hepatic arteries from 165 patients undergoing liver transplantation who were placed into two etiological groups: an Alcoholism group and a Non-alcoholism group. We compared the age, sex, lipid profile, and histologic characteristics of the hepatic arteries (normal, reduction in luminal diameter of ≤10%, or atherosclerosis) of the participants in the two groups using multifactor analyses. Results The Alcoholism group comprised 58 men and 40 women and the Non-alcoholism group comprised 63 men and 4 women. The mean ages of the groups were 52.5 ± 9.6 years and 44.2 ± 13.8 years, respectively. There were no circulating lipid abnormalities in any of the participants. In women, arterial disorders were found at a younger age than in men. Hepatic arterial disorders were more frequent in the non-alcoholic participants, and women with alcoholism showed less arterial narrowing. Conclusion The heavy consumption of alcoholic beverages is associated with a lower incidence of atherosclerosis of the hepatic artery in humans.

“…This work is part of an experimental research line related to trauma and hepatic operations [5][6][7][11][12][13][14][15][16][17][18] . Initially, this study was carried out on rats and rabbits, but results achieved on that preliminary step were inconclusive, due to the lack of specificity in hepatic sclerosis and necrosis because the livers were too small.…”

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 followed during seven days, Group 3 (n = 10)-injection of ethanol inside hepatic parenchyma and animals distribution into two subgroups Subgroup 3A (n = 5)-followed during 24 hours and subgroup 3B (n = 5)-followed during seven days (group 3B), Group 4 (n = 5)-ethanol injection inside left portal vein branch and followed during 24 hours. Livers were macroscopically evaluated, submitted to hepatic arteriography and portography, then histology. Results: All animals in Group 4 died within 23 hours due to diffuse hepatic necrosis. The animals of groups 2 and 3 had a satisfactory evolution. Fibrosis formed in the segment reached by the sclerosant solution and interruption of the contrast flow injected into the portal system. Conclusion: Intrahepatic parenchymal ethanol injection is well tolerated and causes sclerosis restricted to a specific segment; however, intraportal ethanol injection causes massive hepatic necrosis and can lead to death.
