Abdominal fat accumulation with hyperuricemia and hypercholesterolemia quail model induced by high fat diet.
OBJECTIVE
To establish abdominal fat accumulation with hyperuricemia and hypercholesterolemia quail model fed with high fat diet. And then to investigate the pathological characteristics of this quail model.


METHODS
Thirty Longcheng quails were randomly divided into two groups: control group and model group (n=15). The control group quails were fed with normal diet and model group quails were fed with high fat diet for 14 days. After a 12-hour overnight fast, liver and abdominal fat at euthanasia as well as serum were collected. The levels of serum uric acid, total cholesterol, high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), triglyceride, free fatty acid (FFA), and blood glucose were assayed. The activity changes of adenosine deaminase (ADA), xanthine oxidase (XOD), lipoprotein lipase (LPL), hepatic lipase (HL), and fatty acid synthetase (FAS) were analyzed.


RESULTS
Compared with control group, the abdominal fat content (0.74+/-0.63 vs. 1.36+/-0.65 g, P<0.05) and abdominal fat index (0.44%+/-0.30% vs. 0.85%+/-0.30%, P<0.01) as well as live lipid index (3.61%+/-0.65% vs. 11.33%+/-2.14%, P<0.01) in model group significantly increased; the levels of serum uric acid (210.61+/-94.76 vs. 304.25+/-141.94 micromol/L, P<0.05), total cholesterol (4.20+/-0.51 vs. 20.10+/-11.25 mmol/L, P<0.01), LDL-C (1.16+/-0.29 vs. 10.78+/-6.48 mmol/L, P<0.01), and FFA (0.39+/-0.14 vs. 0.55+/-0.15 mmol/L, P<0.01) in model group significantly increased; HDL-C (5.85+/-0.95 vs. 4.14+/-2.03 mmol/L, P<0.05) significantly decreased; the levels of triglyceride and blood glucose had no significant changes (P>0.05); the activities of ADA (9.71+/-3.05 vs. 17.19+/-5.10 U/ml, P<0.01) and XOD (10.58+/-6.88 vs. 19.22+/-9.44 U/L, P<0.01) in model group significantly increased; and FAS, LPL, HL had no significant changes (P>0.05).


CONCLUSIONS
High fat diet can induce abdominal fat accumulation with hyperuricemia and hypercholesterolemia quail model. The changes of uric acid and lipid metabolic enzyme activities may be the pathological mechanism of abdominal fat accumulation with hyperuricemia and hypercholesterolemia.
