In this study,the structural characteristics of Semen coicis native starch,high-amylose maize starch,and heat-moisture treated Semen coicis resistant starch were investigated. The field emission scanning electron microscopy results indicated that compared to Semen coicis native starch and high-amylose maize starch,the surface of heat-moisture treated Semen coicis resistant starch was rough and full of irregular layered strips. The Fourier transform infrared spectroscopy measurements indicated the degree of ordered structure values of Semen coicis native starch,high-amylose maize starch,and heat-moisture treated Semen coicis resistant starch are 1.355,1.372,and 1.410,respectively,and the degree of double helix values is 1.931,1.942,and 2.027,respectively,indicating that the degree of ordered structure and double helix structure of heat-moisture treated Semen coicis resistant starch is both higher than those of Semen coicis native starch and high-amylose maize starch. ^(13) C nuclear magnetic resonance spectroscopy showed that Semen coicis native starch and high-amylose maize starch exhibited A-type crystal structures,while heat-moisture treated Semen coicis resistant starch displayed B-type crystal structures. The relative crystallinity of Semen coicis native starch,high-amylose maize starch,and heat-moisture treated Semen coicis resistant starch is 76.41,85.36,and 87.25,respectively,and the percentages of amorphous region are 5.78,4.72,and 4.39,respectively. Additionally,heat-moisture treated Semen coicis resistant starch could increase the proliferation of Bifidobacterium bifidum more than Semen coicis native starch or high-amylose maize starch. Bifidobacterium bifidum displayed a higher tolerance under simulated gastrointestinal tract conditions such as low p H,bile acid,pepsin,and trypsin in heat-moisture treated Semen coicis resistant starch medium than in Semen coicis native starch or high-amylose maize starch media.展开更多

In all but the normal and sham surgery groups the left half of Tlo was transected. Four hours after model induction, 5-Hz and 100-Hz electroacupuncture were used to stimulate the acupoints I-luantiao (GB 30), Zusan/i (ST 36), Zhiyan9 (DU 9) and Xuanshu (DU 5), or crude extract from semen coicis was intraperitoneally injected, for 8 consecutive weeks. The results indicated that electroacupuncture stimulation and intraperitoneal injection of semen coicis improved the morphology of spinal cord tissue, promoted the recovery of motion-evoked potentials, suppressed glial fibrillary acidic protein expression, and ameliorated motor function in rats with hemisection spinal cord injury. The effects of high-frequency (100 Hz) electroacupuncture ancl semen coicis were significant.展开更多
