Abstract:
ObjectiveTo observe the changes of uric acid level and lipid spectrum, and activities lipid metabolism related enzyme as well as uric acid metabolism-related enzymes on quail abdominal obesity model and then investigate the underlying mechanism of abdominal obesity combined with blood lipid spectrum disorder and hyperuricemia model. MethodsThe quail model of abdominal obesity was induced by feeding with high-fat diet.The body weight and abdominal fat content were measured and the abdominal fat index was calculated. The levels of total cholesterol (TC), high density lipoprotein cholesterol, low density lipoprotein cholesterol (LDL-C), triglyceride (TG), glucose, and uric acid in serum were determined. The changes of adenosine deaminase (ADA),xanthine oxidase (XOD), lipoprotein lipase (LPL), hepatic lipase (HL), and total esterase (TE) activities were also determined. ResultsOn the 7th day, the body weight, abdominal fat content, and abdominal fat index were not significantly different between the model group and control group ( all P ＞0.05 ). On the 14th day, the body weight was not significantly different between these two groups ( P ＞ 0.05 ), while the abdominal fat content [(3.91 ±2. 13) vs. (2.40±0.96) g, P=0.0468] and abdominal fat index (1.92％ ±0.97％ vs. 1.22％ ±0.45％, P =0.0447) were significantly higher in the model group. On the 7th and 14th day, the levels ofTC (P =0.0042 and P =0.0006, respectively), LDL-C ( P =0.0045 and P =0.0010, respectively) in the model group were significantly higher than those in control group, while the level of TG significantly decreased ( P =0.0006 and P =0.0024, respectively ). On the 7th day, compare with the control group, the activities of ADA ( P =0.0237 )and XOD (P =0.0142) in the model group significantly increased, while the activities of LPL, HL, and TE had no significant changes. On the 14th day, compared with the control group, the activities of ADA ( P =0.0060),XOD ( P =0.0071 ), and LPL ( P =0.0419) in the model group significantly increased, while the activities of HL and TE had no significant changes. ConclusionsHigh-fat diet can induce disorders in blood lipid profiles in quail model, but also may incur abdominal obesity and multiple metabolic disorders. Changes in the activities of uric acid and lipid metabolism related enzymes may be the underlying mechanism of disorders in blood lipid profile and its associated hyperuricemia and abdominal accumulation.
