Abstract:
Objective To launch systematic research on long-term asymptomatic hyperuricemia (HUA) from hemorheological viewpoint,so as to provide references for clinical treatment of asymptomatic HUA.Methods Twenty rats were randomly and evenly divided into normal control group and model group.The rats were intraperitoneally injected with 250 mg/(kg · d) oxonate for 8 weeks to induce the model of asymptomatic HUA.The blood samples were obtained to measure the serum uric acid,hemorheological parameters,oxidative and anti-oxidative indices.Results The aggregation index,haemolysis rate,serum xanthine oxidase (XOD),plasma fibrinogen and blood viscosity significantly increased,while the orientation index,electrophoresis rate,serum superoxide dismutase (SOD),activated partial thromboplastin time (APTT) and prothrombin time (PT) significantly induced.Conclusions The asymptomatic HUA can lead to more serious oxidative stress,deteriorate the hemorheological parameters of red blood cells in rats,and induce higher blood viscosity and coagulation status.The research findings indicate that asymptomatic HUA should be correctly understood and timely intervened in clinical diagnosis.
