摘  要:目的研究青稞中β-葡聚糖对高脂膳食诱导的c57小鼠血糖、血脂的影响。方法取C57BL/6雄性小鼠40只,采用随机数字表法,按体重分层随机分为4组(每组10只):β-葡聚糖高剂量组(4%β-葡聚糖+高脂饲料)、低剂量组(2%β-葡聚糖+高脂饲料)、高脂组及基础组。观察其摄食量及体重变化情况。干预的第11周末,进行葡萄糖耐量试验,并测定空腹血糖。第12周末测其体重,处死小鼠,留取血液标本测定血液相关生化指标。结果β-葡聚糖高剂量组、β-葡聚糖低剂量组、高脂组和基础组体重分别为(32.8±1.5)、(40.4±1.9)、(40.7±2.1)、(33.5±1.3)g(F=55.26,P〈0.05);平均摄食量分别为(3.48±0.56)、(3.69±0.76)、(3.66±0.81)、(3.54±0.61)g/d(F=0.26,P〉0.05);空腹血糖分别为(5.29±1.59)、(6.13±1.75)、(7.63±1.09)、(4.24±0.98)mmol/L(F=9.54,P〈0.01);血清胰岛素水平分别为(1.97±0.10)、(2.44±0.24)、(3.02±0.36)、(1.48±0.28)ng/ml(F=47.58,P〈0.01);葡萄糖耐量试验曲线下面积分别为(25.81±1.44)、(30.42±2.01)、(35.17±1.20)、(21.03±1.24)mmol·L-1·h-1(F=64.98,P〈0.05);胰岛素抵抗指数分别为(9.84±3.78)、(13.69±4.48)、(21.54±3.27)、(5.81±1.59)(F:30.18,P〈0.01);血清TC水平分别为(4.05±0.88)、(4.30±0.48)、(4.73±0.66)、(3.37±0.40)mmol/L(F=6.70,P〈0.01);血清TG水平分别为(0.90±0.09)、(0.98±0.09)、(1.05±0.06)、(0.76±0.26)mmol/L(F=6.75,P〈0.01);血清HDL-C水平分别为(2.91±0.59)、(3.34±0.46)、(4.89±0.42)、(3.24±0.37)mmol/L(F=31.73,P〈0.01);血清LDL—C水平分别为([ Abstract] Objective Study the effects of [3-glucan in highland barley on blood glucose and serum lipid in high fat diet induced C57 mouse. Methods Using table of random number,40 male C57BL/6 mice were randomly divided into 4 groups (10 mice in each group) by weight: high dosage group (4% 13-glucan and high fat diet ), low dosage group (2% 13-glucan and high fat diet ), high fat diet group and normal control group. Food-intake and body weight of C57 mouse were observed. Glucose tolerance tests and examinations of fasting blood glucose were performed at the end of 11 weeks of intervention. Mice were sacrificed after 12 wk of treatment, and serum specimens were obtained to test relevant biochemical indicators. Results After 12 weeks raise, among high dosage group, low dosage group, high fat diet group and normal control group, the weight was ( 32. 8± 1.5 ), (40.4±1.9 ) , (40. 7±2. 1 ) and ( 33.5±1.3 ) g, respectively ( F = 55.26, P 〈 0.05); average food intake was (3.48±0.56),(3.69±0.76),(3.66+0.81) and (3.54±0.61) g/d respectively ( F = 0. 26,P 〉 0. 05 ) ; fasting blood-glucose was ( 5.29±1.59 ), ( 6. 13±1.75 ), ( 7.63±1.09) and (4. 24±0. 98 ) mmol/L respectively ( F = 9.54, P 〈 0. 01 ) ; serum insulin level was ( 1.97±0. 10 ), ( 2. 44±0. 24), ( 3.02±0. 36 ) and ( 1.48±0. 28 ) ng/ml respeetively( F = 47.58, P 〈 0. 01 ) ; the area under blood glucose concentration curve was (25.81±1.44) , (30. 42±2.01 ) , (35.17±1.20) and (21.03 ±1.24) mmol· L-1 . h-1 , respectively ( F = 64. 98, P 〈 0. 05 ) ; insulin resistance index was (9.84±3.78),(13.69 ±4.48),(21.54±3.27) and (5.81±1.59) respectively (F=30.18,P〈 0.01); serum total cholesterol (TC) level was (4.05 +0.88), (4.30 -+0.48), (4.73±0.66) and (3.37±0.40) mmol/L respectively (F = 6.70, P 〈 0.01); serum triglyceride (TG) level was (0. 90±0. 09 ) , (0. 98±0
