RESUMEN
Objective To investigate the duodenum absorptive character of monosialotetrahexosylganglioside sodium (GM1) in rats.Methods The contents of phenolsulfonphthalein (as indicators) and GM1 were determined with ultraviolet-visible (UV) method and high performance liquid chromatography (HPLC) method in rats with in situ cycle intestinal perfusion model.Results The ratio of duodenum absorption of GM1 was 10％ in 2 h after cycle and 22％ in 6 h after cycle,respectively.The Ka was (0.030± 0.012)h,and absorption t1/2 was (25.50 ± 8.56)h in 8 h after cycle.Conclusions GM1 is absorption in rat duodenum,and the accumulate absorption of GM1 is almost linearly related to the cycle time.The absorption dynamics of GM1 may be first-order kinetic process.
RESUMEN
ObjectiveTo assess the relationship between central obesity and metabolic syndrome (MS) in community population.MethodsOne thousand and fifty-three individuals aged≥18 (mean,45.6),including 542 men and 511 women,were recruited for questionnaire survey and medical exarmnation from 4 communities of Hangzhou during March and November 2007.Their blood pressure,waist circumference,serum glucose,lipid profile,and other biochemical markers were measured.All data were used for variance analysis.ResultsThe prevalence of MS,central obesity,hypertension,and diabetes mellitus (DM) was 11.2%,23.6%,30.5%,and 8.5%,respectlvely.The prevalence of MS,DM,and hypertension was increased with waist circumference(P<0.05).Waist circumference was positively correlated to body mass index (BMI).systolic blood pressure(SBP),diastolic blood pressure(DSP),fasting blood sugar,total cholesterol,and triglyceride (r=0.812,0.649,0.712,0.657,0.598,and 0.676,respectively),although negativelv with high-density lipoprotein cholesterol(r=-0.578).Waist circumference also showed positive rclationship with the number of lipid metabolism abnormity(r=0.658,P<0.01).CondusionFor Hangzhou community population.central obesity might be one of the risk factors of MS.
