To study the protective effect of Blueberry against rat hepatic fibrosis and the effect of Blueberry on HO-1 expression patterns.


A total of 45 SD rats were randomly divided into five groups namely control group (group A), model group (group B), blueberry group (group C), Dan-shao-hua-xian (DSHX) capsule group (group D) and blueberry +Dan-shao-hua-xian group (group E). Fibrous liver models in rats were induced by subcutaneous injection of CCl4 and high-lipid/low-protein diet for 8 weeks except the control group which accepted saline alone. The level of alanine aminotransferase (ALT) in serum was examined. The activities of superoxide dismutase (SOD) and malondialdehyde (MDA) in liver homogenates were determined. by the xanthine oxidase method and the thiobarbituric acid method. The pathology of hepatic fibrosis was evaluated by hematoxylin and eosin (H and E) staining. The Expression of HO-1 was detected by real-time RT-PCR, immunohistochemical techniques and western blotting.


Serum ALT levels in every prevention group was lower than the group B [(149.44+/-16.51), (136.88+/-10.07), (127.38+/-11.03) vs (203.25+/-31.62) U/L, F = 92.498, P < 0.05], the SOD of liver homogenate in prevention group was significantly higher and the MDA was lower compared with the group B [SOD: (1.36+/-0.09), (1.42+/-0.13), (1.50+/-0.15) vs (1.08+/-0.19) U/mg, F = 13.671, P < 0.05; MDA: (0.294+/-0.026), (0.285+/-0.025), (0.284+/-0.028) vs (0.335+/-0.056) nmol/mg, F = 20.809, P < 0.05]. The pathological stages of hepatic fibrosis were all significantly reduced in prevention group (Chi2 test = 24.956, P < 0.05). Compared with group A, the mRNA and protein expressions of HO-1 were elevated (F = 4.549, 22.926, P < 0.05) in group B and increased in group C-E, but there is no significant difference existed.


Blueberry may have preventive and protective effects on CCl4-induced hepatic fibrosis by reducing lipid peroxidation. However, these effects may not be related to the activation of HO-1 during long-term of CCl4.
