Aim: Comparison of serum cholesterol values of obese with normal subjects and comparison of BMI of obese and normal individuals. Methods: Selection of obese subjects was according to the WHO (1998) criteria. A total of 40 subjects 18 - 55 years of age participated in the study, among which 30 subjects (Mean Age = 29.47 ± 1.99) were obese (Mean BMI = 35.41 ± 0.878) and 10 were controls with Mean age = 21.00 ± 0.547 and BMI = 19.96 ± 0.432. An overnight fasting blood sample was obtained and serum total Cholesterol (T-CH) level was estimated. Results: Obese persons having Mean T-CH = 202.6 ± 14.3 and controls having Mean T-CH = 173.3 ± 14.0. The data were further divided into males and females. Obese females were 11 with their BMI 31.836 ± 0.21, mean age ranged at 28.73 ± 4.04 and T-CH 191.8 ± 21.8, while that of control females were 6 in number with their BMI ranged at 19.183 ± 0.507, age 21.000 ± 0.894 and Cholester 148.7 ± 16.0 in controls. Total numbers of obese males were 19 with their BMI ranged at 37.49 ± 1.14, age ranged at 29.89 ± 2.19 and cholesterol level ranged at 208.89 ± 19.1. Control males were 4 in number with their BMI ranged at 21.125 ± 0.075, age 21.250 ± 0.479 and their T-CH 128.7 ± 8.72. Conclusion: The results of current study have reflected that BMI and total cholesterol concentration are higher in obese subjects.展开更多

文摘目的:分析Leber先天性黑矇(Leber congenital amaurosis,LCA)患者血清脂质浓度的变化。方法:采用回顾性序列病例研究方法,选取临床诊断为LCA的患者50例作为LCA组,选取52例正常人作为正常对照组,按盲法由专业技术人员测量两组受检者血清中低密度脂蛋白胆固醇(low density lipoprotein cholesterol,LDL-C)、高密度脂蛋白胆固醇(high density lipoprotein cholesterol,HDL-C)、甘油三酯(triglycerides,TG)、总胆固醇(total cholesterol,TC)含量,并对两组受检者的测量结果进行比较。结果:LCA患者50例中,血脂水平异常者占46%,其中低HDL-C血症者占26%,高TG血症者占48%,高TC血症者占17%,混合型高脂血症者占9%。LCA患者血清HDL-C浓度为1.221±0.317mmol/L,较正常对照组明显下降,差异有统计学意义(P<0.05);血清TG浓度(1.377±1.171mmol/L)和TC浓度(4.506±0.694mmol/L)与正常对照组相比均明显升高,差异有统计学意义(均P<0.01);LDL-C浓度与正常对照组相比,差异无统计学意义(P>0.05)。结论:LCA患者血清HDL-C、TG和TC浓度异常变化可能与LCA的发病相关。
