Multiprobiotic therapy from childhood prevents the development of nonalcoholic fatty liver disease in adult monosodium glutamate-induced obese rats

Abstract

Considering the association between microflora and obesity, and the significantly higher prevalence of non-alcoholic fatty liver disease (NAFLD) in obese people, the aim of our study was to investigate the preventive effect of multiprobiotics on the monosodium glutamate (MSG) induced NAFLD model, in rats. The work was carried out on 60 rats placed into three groups: the Control group, the MSG-group and the MSG-probiotic group. The MSG-group and the MSG-probiotic group were injected with 4 mg/g of MSG subcutaneously neonatally on the 2nd-10th days of life. The MSG-probiotic rats were also treated with 140 mg/kg of multiprobiotic “Symbiter” from the 4th week of life. In the 4-month-old rats, biochemical and morphological changes in liver were assessed, and steatosis was confirmed by the NAFLD activity score (NAS). Our results reveal that the multiprobiotic lowered total NAS, the degree of steatosis and the liver lobular inflammation caused by MSG. It also brought about decreased liver total lipids and triglycerids content, as well as decreased visceral adipose tissue mass. However, there was no difference in the liver serum biochemical indicators between all experimental groups. The obtained data does suggest the efficacy of probiotics in the prevention of NAFLD.

Hepatic stellate cells activation and liver fibrosis after chronic administration of ethanol

Abstract

Hepatic stellate cells (HSC) are a nonparenchymal population of liver cells. In normal conditions, they store vitamin A, control the turnover of the extracellular matrix, and regulate the contractility of the sinusoids. Acute and chronic damage such as that brought about by alcohol activates the stellate cells and they are then responsible for the liver's inflammatory fibrotic response. Hence, alcohol consumption leads to hepatitis, steatosis, fibrosis and cirrhosis of liver by way of different mechanisms depending on effect upon the nonparenchymal cells of the liver.

The aim of our study was to assess the histological changes in the liver of rats after chronic alcohol consumption. In our work, we evaluated the intensity of liver fibrosis and the number of Kupffer cells and active hepatic stellate cells present within a test population. In the experiment, we used 10 Wistar rats of 250 gram weight. The animals were placed within one of two groups: A (experimental) and C (control). Group A received alcohol for 4 weeks, while group C received just water. The rats of both groups were decapitated 24 hours after the end of the experiment. The samples of liver were then evaluated after H&E, Masson’s trichrome staining and an immunohistochemical reaction to desmin (a marker of quiescent HSC) and α-smooth muscle actin (marker of active HSC) antibody. In our work, we observed intensive fibrosis in the portal spaces and perivenular areas in group A samples. Moreover, Kupffer cells and stellate cells with positive α-SMA expression were more numerous in group A than in the group C, and these correlate with the area of intensive fibrosis. The expression of desmin in the HSC was seen in both groups to a similar level.

Conclusion: Chronic alcohol consumption activates the transdifferentiation of hepatic stellate cells into the positive α-SMA myofibroblast-like cells which are responsible for fibrogenesis.
