Abstract
AIM: To investigate the therapeutic effects of fistular onion stalk extract on nonalcoholic fatty liver (NAFL) in rats.
METHODS: Sixty-four Wistar rats were randomly divided into two groups: blank control group (n = 8) and fat milk group (n = 56). The fat milk group was intragastrically given fat milk once a day to induce NAFL. After induction of NAFL, eight rats from each group were killed. The remaining rats of the fat milk group were further randomly divided into six subgroups: model control subgroup, Jiaogulan subgroup, polyene phosphatidylcholine subgroup, and low-, medium- and high-dose fistular onion stalk extract subgroups. Except the model control subgroup, each of the other subgroups was given the corresponding drug. After 8 weeks, all the animals were sacrificed. The contents of plasma total triglyceride (TG), cholesterol (TC), high-density lipoprotein (HDL), and low-density lipoprotein (LDL) were determined. The levels of malondialdehyde (MDA) and superoxide dismutase (SOD) in liver tissue were measured by spectrophotometry. Enzyme-linked immunosorbent assay (ELISA) was used to determined the changes in the content of TNF-α in the liver.
RESULTS: Compared with the model control subgroup, serum lipid levels showed different degrees of improvement in the low-, medium- and high-dose fistular onion stalk extract, Jiaogulan and polyene phosphatidylcholine subgroups: the levels of TG, TC and LDL decreased significantly (TG: 0.57 mmol/L ± 0.05 mmol/L, 0.51 mmol/L ± 0.04 mmol/L, 0.58 mmol/L ± 0.05 mmol/L, 0.52 mmol/L ± 0.05 mmol/L and 0.50 mmol/L ± 0.03 mmol/L vs 0.73 mmol/L ± 0.06 mmol/L, all P < 0.01; TC: 2.04 mmol/L ± 0.18 mmol/L, 1.69 mmol/L ± 0.15 mmol/L, 2.03 mmol/L ± 0.41 mmol/L, 1.88 mmol/L ± 0.18 mmol/L and 1.70 mmol/L ± 0.39 mmol/L vs 3.42 mmol/L ± 0.42 mmol/L, all P < 0.01; LDL: 0.41 mmol/L ± 0.05 mmol/L, 0.36 mmol/L ± 0.12 mmol/L, 0.46 mmol/L ± 0.13 mmol/L and 0.40 mmol/L ± 0.15 mmol/L vs 0.81 mmol/L ± 0.24 mmol/L, all P < 0.01); the levels of MDA and TNF-α were reduced significantly (all P < 0.01); and SOD activity increased (61.79 U/mg ± 5.72 U/mg, 83.03 U/mg ± 7.47 U/mg, 70.51 U/mg ± 4.84 U/mg, 66.66 U/mg ± 9.23 U/mg and 73.12 ± 4.87 U/mg vs 49.50 U/mg ± 9.31 U/mg, all P < 0.01).
CONCLUSION: Fistular onion stalk extract may exert a protective effect on liver function by decreasing the levels of TG and TC and the activity of MDA and increasing the activity of SOD.
