Background & Aims
Resveratrol, a polyphenol found in a variety of fruits, exerts a wide range of beneficial effects on the endothelium, regulates multiple vasoactive substances and decreases oxidative stress, factors involved in the pathophysiology of portal hypertension. Our study aimed at evaluating the effects of resveratrol on hepatic and systemic hemodynamics, hepatic endothelial dysfunction, and hepatic fibrosis in CCl4 cirrhotic rats.
Resveratrol (10 and 20 mg/kg/day) or its vehicle was administered to cirrhotic rats for two weeks and hepatic and systemic hemodynamics were measured. Moreover, we evaluated endothelial function by dose-relaxation curves to acetylcholine, hepatic NO bioavailability and TXA2 production. We also evaluated liver fibrosis by Sirius Red staining of liver sections, collagen-1, NFκB, TGFβ mRNA expression, and desmin and α-smooth muscle actin (α-SMA) protein expression, as a surrogate of hepatic stellate cell activation.
Resveratrol administration significantly decreased portal pressure compared to vehicle (12.1 ± 0.9 vs. 14.3 ± 2.2 mmHg; p <0.05) without significant changes in systemic hemodynamics. Reduction in portal pressure was associated with an improved vasodilatory response to acetylcholine, with decreased TXA2 production, increased endothelial NO, and with a significant reduction in liver fibrosis. The decrease in hepatic fibrosis was associated with a reduced collagen-1, TGFβ, NFκB mRNA expression and desmin and α-SMA protein expression.
Resveratrol administration reduces portal pressure, hepatic stellate cell activation and liver fibrosis, and improves hepatic endothelial dysfunction in cirrhotic rats, suggesting it may be a useful dietary supplement in the treatment of portal hypertension in patients with cirrhosis.
This is really interesting, thank you so much for posting. There used to be a member on here HepatitisResearcher, an MD who said that resveratrol would help us. Nice to see that it is being documented. Thank you Dee
Thank you for posting it. It seems like a catch 22. There is resveratrol in the skin of red grapes, in red wine. Yet drinking too much wine will give you cirrhosis.
I guess snacking on red grapes doesn't hurt anyone and could be beneficial.:)
i am waiting to see liposomal curcumin, there is a study reporting super anticancer and antinflammatory properties, dont remember if vivo or vitro
this is what they have under development:
• Intra-Cellular Curcumin Cu (ll)
• Intra-Cellular Full Spectrum Omega
• Intra-Cellular CoQ10
• Intra-Cellular Alpha Lipoic Acid with Magnesium
• Intra-Cellular Multi-Vitamin (The world's first)
it would be interesting to ask if they can develop this:
Polyunsaturated liposomes are antiviral against hepatitis B and C
